[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift operation input device for an automatic transmission, and more particularly, to an automatic shift range for automatically changing a gear position based on a preset shift characteristic.
A shift operation input device of an automatic transmission provided with a manual shift range in which a gear is switched by a swing operation of a shift lever by a driver, particularly, a hydraulic supply state for each range is selectively selected by moving in an axial direction. The present invention belongs to the technical field of a shift operation input device of an automatic transmission provided with a manual valve.

[0002]

2. Description of the Related Art In recent years, as an automatic transmission for a vehicle, in addition to an automatic shift range in which an automatic shift that automatically switches gears based on a preset shift characteristic is achieved,
An automatic transmission having a manual shift range in which a manual shift in which a shift stage is switched by swinging a shift lever in a predetermined direction is being put into practical use. There is one disclosed in the gazette.

In this automatic transmission, P (parking), R (reverse), and N (reverse) are performed by swinging a shift lever in a first shift gate extending in the vehicle longitudinal direction.
(Neutral), D (drive), and other ranges can be selected. Automatic shifting is achieved in the D range, and the shift lever is moved through a communication gate extending laterally from the selected position in the D range. Switching to a second shift gate for a manual shift range (M range) in which manual shifting is achieved in parallel with the first shift gate, and in this second shift gate, the shift lever is rocked forward from a neutral position. The shift operation shifts the gear up by one step, and the swinging operation shifts the gear to one step.
It is configured to shift down by one step.

In this type of automatic transmission, clutches and brakes are generally used to selectively engage or disengage in response to supply and discharge of operating pressure, thereby switching a power transmission path between an engine and driving wheels. A plurality of friction elements are provided, and a valve member (manual) for switching a hydraulic oil passage in the circuit in accordance with each range to a hydraulic control circuit for controlling the supply and discharge of the operating pressure to the friction elements. Valve). And
A cable is arranged between the valve member and the shift lever via, for example, a mechanical interlocking mechanism. It is transmitted to the valve member in the hydraulic control circuit via a cable via a mechanical interlocking mechanism,
The valve member is moved in accordance with the range selected by the shift lever, whereby an oil passage for the range is realized, and a hydraulic pressure supply state for the range is achieved.

[0005] In such a case, if the above-described manual shift range is provided along with the automatic shift range, the following problem may occur. That is, P, R, N,
Since the first shift gate for switching between each range such as D and the second shift gate forming the M range are arranged in parallel with each other, the second shift gate (for manual shifting) is provided. The swing direction of the shift lever in the (M range) is the same as the swing direction of the shift lever in the first shift gate for switching between the other ranges. Also, the valve member moves in the hydraulic control circuit via the mechanical interlocking mechanism.

Accordingly, there is a possibility that the oil passage or the hydraulic pressure supply state for the forward travel range set via the valve member may not be properly realized by the movement of the valve member. In the case where the selection position of the N range is arranged in front of the M range, the swing operation of the shift lever from the neutral position of the M range to the upshift position of the front can be performed by shifting the shift lever from the D range to the front N range direction. This is the same operation as performing the swinging operation so as to approach, and as a result, the oil path approaches the direction in which the oil path switches to the N-range oil path, and the operating pressure on the friction element that is fastened during forward running decreases or becomes insufficient. Such troubles may occur.

Therefore, in the above publication, when the shift lever is swung from the selected position of the D range to the selected position of the M range via the communication gate, the link between the lever and the cable is disconnected. Conversely, shift lever to M
When swinging in the direction from the range selection position to the D range selection position, the linkage between the lever and the cable is restored so that range selection within the range from the P range selection position to the D range selection position is performed. As for the swing of the shift lever, the movement of the shift lever is transmitted to the valve member. On the other hand, the swing of the shift lever for manual shifting within the M range selection position is not transmitted to the valve member. Are disclosed.

[0008]

However, according to the technique disclosed in this publication, the link between the cable and the shift lever is disconnected when switching from the D range to the M range, and switching from the M range to the D range is performed. Sometimes it is necessary to have a mechanism for connecting and holding when switching between other ranges, which complicates the mechanical structure of the shift operation input device around the shift lever and increases the number of parts, weight, and cost. .

According to the present invention, there is provided a valve member which is provided with a manual shift range for switching a gear position by swinging a shift lever, and which achieves a hydraulic pressure supply state for each range in conjunction with swinging of the shift lever. In order to cope with the above-mentioned problem in the speed change operation input device provided with a cable member for transmitting the range selection movement of the shift lever to the valve member, the mechanical structure around the shift lever is complicated. It is another object of the present invention to avoid a change in the hydraulic pressure supply state due to the swing of the shift lever in the manual shift range.

[0010]

In order to solve the above problems, the present invention uses the following means.

First, the invention described in claim 1 of the present invention (hereinafter referred to as "first invention") is as follows.
The range selected by the swing operation of the shift lever includes a non-travel range, a forward range, and a reverse range, and the forward range includes an automatic shift range for performing a shift based on a preset shift characteristic. A manual shift range in which a shift is performed by swinging a shift lever is provided, and among the selected positions of these ranges, the selected position of the non-travel range and the selected position of the automatic shift range are adjacent to each other in the first direction. The automatic transmission range selection position and the manual transmission range selection position are disposed adjacent to each other in a second direction orthogonal to the first direction, and the automatic transmission range selection position is within the manual transmission range selection position. A gear shift is performed by swinging a shift lever in a first direction, and a manual switch for switching a hydraulic pressure supply state by moving in an axial direction. A shift operation input device for an automatic transmission, wherein the manual valve is used for a non-travel range, wherein the shift valve is operated via a mechanical interlocking mechanism by swinging a shift lever in a first direction. It is configured such that three hydraulic pressure supply states for the forward range and the reverse range can be selectively achieved, and the manual valve is set between the automatic shift range selected position and the manual shift range selected position. A manual valve operating means for maintaining the hydraulic pressure supply state for the forward range within the swing range of the shift lever in the first direction is provided.

Further, the invention according to claim 2 (hereinafter referred to as “second
Invention ". In the first aspect, the manual valve operating means is provided in the mechanical interlocking mechanism so as not to transmit the swing of the shift lever in the swing range within the selected position of the manual shift range to the manual valve. It is characterized by having been done.

Further, according to a third aspect of the invention (hereinafter referred to as a "third invention"), in the first invention, the manual valve operating means rotates in conjunction with the swinging of the shift lever, and the manual valve operating means rotates. A plate member provided with an engagement groove that engages with an engagement portion provided on the valve; and the manual valve is moved in the axial direction by moving the engagement portion in the engagement groove by rotation of the plate member. When the manual valve is in a position for achieving the hydraulic pressure supply state for the forward range, the portion of the engagement groove with which the engagement portion engages is formed by the manual shift range of the shift lever. Is formed in a concentric arc shape with respect to the rotation center of the plate member within the rotation range of the plate member accompanying the swing in the selected position.

According to a fourth aspect of the invention (hereinafter referred to as a "fourth invention"), a parking range and a neutral range are set as non-traveling ranges in any of the first to third inventions. In both of these ranges, the manual valve is configured to achieve a hydraulic supply state for the non-traveling range at the same position.

According to the present invention, the following effects can be obtained by using the above means.

First, according to the first aspect of the present invention, a non-travel range, a forward range, and a reverse range are provided as ranges to be selected by the swing operation of the shift lever. And a selection position of the automatic transmission range as the forward range is disposed adjacent to each other in the first direction, and the selected position of the automatic transmission range and the selection position of the manual transmission range also as the forward range are different from each other. Since it is arranged adjacently in the second direction orthogonal to the first direction and furthermore, the swing of the shift lever for achieving the manual shift in the manual shift range is the first direction, After all, the direction of the swing of the shift lever for switching the range between the automatic shift range and the non-travel range, and the direction of the swing of the shift lever for the manual shift. Not only in parallel with each other and both along the above-mentioned first direction, but also in an operation of swinging the shift lever when switching from the automatic transmission range to the non-traveling range, and One of the operation of swinging the shift lever to shift up or the operation of swinging the shift lever to shift down is the same operation as the above-described swing operation along the first direction. Therefore, if the manual valve for selectively switching the hydraulic pressure supply state according to each range is always operated by swinging the shift lever in the first direction, the manual shift range selection position When the shift-up operation or the shift-down operation is performed in the above, the hydraulic supply state achieved for the forward range is changed to the oil for the non-travel range. Close to the supply state, whereby the actuating pressure supplied to the friction element to be fastened is reduced at the time of forward traveling, so that the trouble such as the fastening force of the friction element is insufficient arises.

However, according to the first aspect, the manual valve operating means is provided, and the manual valve allows the manual valve to select not only when the automatic shift range is selected but also when the manual shift range is selected. ,
Even when the shift lever is swung in the first direction so that the manual shift is achieved in the manual shift range, as long as the shift lever is within the swing range, the hydraulic pressure supply state for the forward range is provided. Therefore, even if the shift lever is swung along the first direction for upshifting or downshifting within the manual shift range achieving position, the hydraulic pressure supply state for the forward range is maintained, whereby In addition, problems such as a decrease in the operating pressure supplied to the friction element that is fastened during forward running and an insufficient fastening force of the friction element can be avoided, and the shift lever can be moved from the automatic shift range attainment position by the same operation. When swinging along the first direction toward the travel range achievement position, the hydraulic pressure supply state is switched from the forward range to the non-travel range.

In this case, the manual valve operating means holds the manual valve in the hydraulic pressure supply state for the forward range, and does not mechanically disconnect the shift lever and the cable, for example. Therefore, the mechanical structure around the shift lever is not complicated, and increases in the number of parts, weight, and cost can be avoided.

On the other hand, according to the second invention, the manual valve operating means is provided in a mechanical interlocking mechanism provided as a necessary device from the beginning, and the manual operation of the shift lever as a manual shift operation is performed. No movement is transmitted to the manual valve, so no matter how much the shift lever is swung to shift up or down within the position where the manual shift range is achieved, the manual valve moves in the axial direction Therefore, the switching of the hydraulic pressure supply state is reliably avoided.

Further, according to the third invention, in particular, the manual valve operating means has a plate member, and the engagement groove of the plate member and the engagement portion of the manual valve are engaged, so that the shift lever When the plate member rotates in conjunction with the swing, the engaging portion moves in the engaging groove, whereby the manual valve is configured to move in the axial direction. When the hydraulic pressure supply state is achieved, the portion of the engagement groove with which the engagement portion engages is within the rotation range of the plate member accompanying the swing of the shift lever at the time of manual gear shifting. Since it is formed in a concentric arc shape with respect to the rotation center, no matter how much the plate member rotates within this range,
The manual valve does not move in the axial direction in conjunction therewith, whereby switching of the hydraulic supply state is reliably avoided.

Further, by forming the engagement groove of the plate member in such a shape, for example, the automatic transmission range is not provided, and instead of the D range, an S range or an L range is provided as a forward range. Even in an automatic transmission in which the range selection positions are arranged adjacent to each other to maintain the hydraulic pressure supply state for the forward range in each of these D, S, and L ranges, the plate member or the mechanical transmission An interlocking mechanism or a manual valve can also be used, and parts can be shared, which can contribute to an improvement in productivity.

According to the fourth invention, in particular, the parking range and the neutral range are non-traveling ranges, and regardless of which range is selected, the manual valve moves to the same position and the non-traveling range is used. Since the hydraulic pressure supply state is achieved, the manual valve moves to a different position between when the parking range is selected and when the neutral range is selected, and the same hydraulic pressure supply for the non-travel range is used in both positions. As compared with the case where the state is achieved, the shapes of the manual valve, the hydraulic control circuit, and the oil passage do not have to be complicated.

3. More specifically, it comes into contact only with the edge of the shift gate 13, but not with the opening 2a of the cover 2. Therefore, the swing of the shift lever 3 is restricted by the contact between the shift lever 3 and the shift gate 13, whereby the swing path of the shift lever 3 is substantially determined by the shape of the shift gate 13. The swing path of the shift lever 3 is the first to ninth communication paths G1 to G

Then, as shown in FIG. 1, the position of the shift lever 3 in the figure, that is, the start end of the first communication path G1 is P
The selection positions of the range are set in the order from the rear to the rear, and the selection positions of the R range, the N range, and the D range are arranged along the swing path of the shift gate 13 or the lever 3. The end of the third communication path G3 and the start end of the fourth communication path G4 are at the R range selection position, the end of the fifth communication path G5 and the start end of the sixth communication path G6 are at the N range selection position, End of sixth communication path G6 and seventh communication path G
The start end of 7 is a selection position of the D range.

The automatic forward shift is achieved by switching the gear position based on the following, but an M range is provided separately from the D range as the same forward travel range,
When the M range is selected, a manual shift for changing the gear position according to the swing of the shift lever 3 is achieved. The position for selecting the M range is also arranged along the swing path of the shift gate 13 or the lever 3, and specifically, as shown in FIG. The end of the seventh communication path G7 and the start ends of the eighth and ninth communication paths G8, G9 are in the neutral position of the M range, and the end of the eighth communication path G8 is shifted up in the M range to shift the gear by one step.

The swing operation of the shift lever 3 in the “select direction” is appropriately referred to as “select operation”. ), And swing back along the second communication path G2 (hereinafter, shift lever 3).
This direction in which is pivoted is appropriately referred to as a “shift direction”, and the swing operation of the shift lever 3 in the “shift direction” is appropriately referred to as a “shift operation”. Then, the R range is selected by swinging to the right in the select direction along the third communication path G3, and after further swinging backward in the shift direction along the fourth communication path G4, The N range is selected by swinging to the right in the select direction along the fifth communication path G5, and the D range is selected by further swinging back in the shift direction along the sixth communication path G6.

As will be described later, the shift lever 3 is always urged right in the select direction. Therefore, for example, when switching from the P range to the R range,
The operation performed by the driver is to swing the shift lever 3 leftward in the select direction against the above-mentioned biasing force, and then swing backward in the shift direction. When reaching the terminal end of the passage G2, the urging force causes the third communication passage G3 to swing alone to the terminal end.

As described above, in the shift operation input device 1, the shift lever 3 is used as the swing position of the shift lever 3.

The operation width of the lever 3 in the select direction is shorter and more compact than in the conventional case, so that the driver does not feel cramped in the swinging operation of the shift lever 3, and in particular, the manual shift operation in the M range selection position. Feeling cramped during operation is avoided.

Here, as shown in FIG. 3, a slide sheet 14 is sandwiched between the cover 2 and the upper plate 9 so as to close the opening 2a and the shift gate 13. The sliding movement of the slide sheet 14 is enabled only in the front-rear direction.
When the shift lever 3 is engaged with the shift lever 3 through the elongated hole 15 (see FIG. 1) extending in the width direction, and the shift lever 3 is swung in the select direction, the lever 3 is
When the lever 3 is swung in the shift direction, the slide sheet 14 slides in the front-rear direction in conjunction with the swing.

Next, the structure of the portion of the speed change operation input device 1 disposed below the cover 2 will be described in detail.

First, the structure for attaching the shift lever 3 to the base member 6 will be described. As described above, the shift lever 3 can swing on the base member 6 via the case member 12 in the vehicle longitudinal direction and the vehicle width direction. It is supported by.

As shown in FIG. 3, the base member 5 constituting the lower half of the shift lever 3 includes a substantially quadrangular prism-shaped main body 21 into which the columnar member 4 constituting the upper half enters. 2

Then, as shown in FIG.
The lower protruding portion 11 is provided with a support shaft 31 inserted between the left and right side surfaces of the protrusion portion 11.
In addition, the case member 12 is swingably supported in the front-rear direction with respect to the base member 6 and, as shown in FIGS. The support shaft 32 is inserted, and the lower end boss 25 of the base member 5 is rotatably supported by the support shaft 32 in a state where the base member 5 of the shift lever 3 is housed in the case member 12. The shift lever 3 is provided on the case member 12 so as to be swingable in the left-right direction.

Accordingly, the case member 12 is swingable only in the front-back direction with respect to the base member 6, and the shift lever 3 is swingable in the left-right direction with respect to the case member 12. Thus, the shift lever 3 is swingably supported by the base member 6 in the vehicle longitudinal direction and the vehicle width direction.

For example, when the lever 3 is swung in the shift direction, the case member 12 is also swung in the left-right direction with the swing.
When the lever 3 is swung in the select direction while the lever 3 is swung in the front-rear direction around the center 1, only the lever 3 moves in the left-right direction about the second support shaft 32 erected in the front-rear direction. The case member 12 swings and does not swing in the left-right direction in the same manner.

An operation mechanism of a shift-up switch and a shift-down switch that detects an up-operation and a down-shift operation. When the shift lever 3 is not at the P-range selection position, the removal of the engine start key from the key cylinder in the key operation section of the driver's seat is restricted. Key interlock mechanism, more specifically, in the key interlock mechanism P of the shift lever 3 Kkukeburu
A cable moving mechanism that moves in conjunction with the movement to the range selection position, a shift lock mechanism that regulates the selection operation of the shift lever 3 from the P range selection position and the N range selection position, and the like are provided. The structure of each of these mechanisms provided in the shift operation input device 1 will be described in order, and the actions obtained by each mechanism will also be described with respect to the operation of the shift gate 13 or the operation of the shift lever 3 along the swing path. It will be described in connection with the above.

First, the lever biasing mechanism will be described. As shown in FIG. 4, FIG.
And a leaf spring member 42 screwed to the rear surface of the square pillar-shaped main body 21 of the base member 5 of the shift lever 3.

The surface of the standing wall portion 41 on the side of the shift lever 3 is a flat surface that is continuous with the inner surface on the right side of the above-mentioned downward protruding portion 12, but the surface of the wall portion 41 on the side opposite to the shift lever 3. That is, the right outer surface has an arcuate surface 4 formed in the front half thereof so as to be narrower upward and wider downward.
1a.

The leaf spring member 42 is connected to the shift lever 3.
Extends from the base member 5 to the right and passes through an opening 43 formed in the right side surface of the case member 12, and the distal end thereof is engaged with the arc-shaped surface 41 a of the right outer surface of the standing wall portion 41.

In this case, the shift lever 3 is swung to the left in the select direction by the arc-shaped surface 41a of the upright wall portion 41 to which the leaf spring member 42 is locked, so that the leaf spring member 42 is When moving away from the standing wall portion 41 in the left direction, the distal end of the leaf spring member 42 is lifted up along the arcuate surface 41a, and as a result, the leaf spring member 42 tries to push back downward. The upright wall 41 and the leaf spring member 42 are engaged so that a rightward urging force always acts on the shift lever 3 by the engagement between the upright wall 41 and the leaf spring member 42. Has become. The arcuate surface 41a formed in such a shape is erected so that the leaf spring member 42 is locked in a range where the shift lever 3 is between the P range selection position and the N range selection position. It is provided in the front half of the wall 41.

Therefore, when the shift lever 3 is at the P range selection position located at the shift gate 15 or at the rightmost end of the swing path, the lever 3 is stably moved by the rightward urging force. When the shift lever 3 is moved to the R range selection position from the P range selection position, the first communication path G1, the second communication path G2, and the third communication path which are mutually orthogonal between these range selection positions. Passage G
3, it is necessary to first select the lever 3 to the left along the first communication path G1 against the urging force, and the shift lever 3 is operated while the urging force is acting.
Is shifted backward along the second communication path G2. Thereafter, the rightward swing of the lever 3 along the third communication path G3 is performed by the above-described urging force. When the shift lever 3 is located at the R range selection position, the lever 3 is still in a state where a slight urging force is still applied to the right.

On the other hand, the shift lever 3 is moved from the R range selection position to the N range selection position by moving the fourth communication path G4 and the fifth communication path G orthogonal to each other between these range selection positions.
However, since the swing of the lever 3 along the fifth communication path G5 is performed by the above-described urging force, the operation is simply that the lever 3 is still somewhat applied with the urging force. The shift lever 3 can be shifted rearward along the fourth communication path G4 in the state in which the shift lever 3 is moved from the N range selection position to the D range selection position in the shift direction between these range selection positions. Since there is only the sixth communication path G6 extending, the shift lever 3 may be simply shifted backward. When the shift lever 3 is swung to the D range selection position, the leaf spring member 42 of the lever 3 and the arcuate surface 41a of the front half of the wall 41 are formed.
Has been engaged.

Next, the lever operation moderation mechanism will be described. As shown in FIGS. 3, 4, 6, and 7, the mechanism has the opening 43 through which the leaf spring member 42 passes, and a right side surface of the fan-shaped case member 12 in a side view. As shown in FIGS. 2 and 3, a second leaf spring member 44 is provided to extend forward at a position on the rear right side of the shift lever 3.

The upper edge of the fan-shaped right side surface 29 is formed in a substantially arcuate surface centered on a first support shaft 31 which is a pivotal support point of the shift lever 3 in the front-rear direction. Detent recesses p, r, n, and d for positioning for R, R, N, and D / M ranges
Is provided.

The second leaf spring member 44 has a rear end fixed to the rear lower surface of the upper plate 9 using a bolt 45 and a detent pin 46 and extends forward, and has a front end. Are bent engagement portions, which are engaged with the concave portions corresponding to the swing position of the shift lever 3 among the range concave portions p, r, n, and d of the fan-shaped right side surface 28. Thereby, when the shift lever 3 is positioned at each range selection position and the shift lever 3 is swung in the shift direction in a range between the P range selection position and the D range selection position, the shift selection operation is performed. The moderation is given.

On the other hand, as shown in FIG. 4, FIG. 6, and FIG. 7, the rear half of the upright wall portion 41 which constitutes the above-described shift lever urging mechanism has the arcuate shape of the front half for urging the lever. Face 41
a is interrupted, and instead, a curved surface 41b is formed which is also narrower upward and wider downward, the upper end of which is the arcuate surface 4 of the front half for urging the lever.
1a is formed lower than the upper end. When the shift lever 3 is swung to the D range selection position, the first leaf spring member 42 provided on the lever 3 is locked to the bent surface 41b at the rear half of the shift lever 3, and the shift lever 3 Is swung in the select direction between the D range position and the M range selection position disposed on the left side of the D range position, the first leaf spring member 42 resists its elastic restoring force. In this way, it is possible to get over the middle mountainous part of the curved surface 41b in the latter half. Thereby, when the shift lever 3 is swung in the select direction between the D range selection position and the M range selection position,
A moderation feeling is given to the range selection operation.

During the selection operation between the D and M ranges, the shift lever 3 is swung in the select direction as described above, but the lever 3 and the case member 12 are moved in the select direction. Since it does not swing together, the engagement between the fan-shaped right side surface 29 of the case member 12 and the second leaf spring member 44 remains in the D and M range dual-purpose detent recess d.

As described above, for the range selection operation in the shift direction within the range between the P range selection position and the D range selection position, the fan-shaped right side surface 29 and the second leaf spring member 4
4 provides a sense of moderation, and the range selection operation between the D range selection position and the M range selection position in the selection direction orthogonal to the shift direction is performed in the latter half of the upright wall portion 41. The moderation feeling is given by the engagement between the bent surface 41b of the portion and the first leaf spring member 42.

Next, the neutral biasing mechanism of the shift lever 3 in the M range selection position, the operating mechanism of the M range switch, and the operating mechanisms of the shift up switch and the shift down switch will be described together.

As shown in FIGS. 3, 5, 6 and 7,
The first support shaft 31 provided on the lower projecting portion 11 of the base member 6 and swingably supporting the case member 12 has a notch 50a at the upper edge on the left side of the case member 12. The formed long lever body 50 is pivotally supported to be swingable in the front-rear direction. Further, the rear end of the third leaf spring member 51 is provided with the bolt 52 and the detent at the left lower position on the rear lower surface of the upper plate 9 so as to be arranged in parallel with the second leaf spring member 44. The third leaf spring member 51 extends forward toward the upper edge of the lever body 50.

The front end of the leaf spring member 51 is bent to form an engagement portion 51a, and a detent recess 50b is formed at the upper edge of the lever body 50 behind the notch 50a. The engagement portion 51a of the leaf spring member 51 and the detent recess 5 of the lever body 50
0b is engaged with the lever body 50.
Is biased and held at a predetermined position by the leaf spring member 51.

On the other hand, as described above, as the range is selected in order from the P range to the R range, the N range, and the D range, the shift lever 3 is swung rearward in the shift direction. Lever 3 is in the sixth communication path G6
When the lever 3 is swung from the selection position of the N range to the selection position of the D range along the arrow, the base member 5 of the lever 3 is biased and held at a predetermined position by the third leaf spring member 51. More specifically, the shift lever 3 is positioned so as to substantially overlap the body 50 in a side view, and the shift lever 3 is shifted leftward in the select direction along the seventh communication path G7 from the selected position of the D range to the selected position of the M range. When the lever is pivoted to the neutral position of the M range, the above-mentioned rectangular pin member 22 formed on the base member 5 of the lever 3 fits into the notch 50a of the lever body 50 at the predetermined position. It has become.

Therefore, when the shift lever 3 is swung back and forth in this state, the lever body 50 is accordingly moved.
Similarly, the swinging of the lever body 50 causes the engaging portion 51a at the tip of the third leaf spring member 51 to be lifted upward. As a result, the shift within the M range selection position is performed. The manual transmission operation of the lever 3
The urging force acts on the neutral position of the range (neutral urging mechanism of the shift lever 3).

As shown in FIGS. 3 and 8, at the rear end of the lever body 50, substantially at the middle in the up-down direction, there is provided an M for detecting that the shift lever 3 has been moved to the M range selection position. A range switch 54 is attached. In this case, the M range switch 54 is arranged such that the section pressed by the on / off operation is arranged on the shift lever 3 side, and the shift lever 3 tilts in the left and right direction when the shift lever 3 is turned to the M range selection position. Correspondingly, the upper part is provided in a state inclined to the left.

Therefore, when the shift lever 3 is swung from the D range selection position to the left in the selection direction along the seventh communication path G7 to the M range selection position,
The left side surface of the quadrangular prism-shaped main body 21 of the base member 5 of the lever 3 presses the section of the M range switch 54, whereby the M range switch 54 is turned on. Therefore, when swinging back and forth, as described above, the lever body 50 also swings integrally, so that the pressing of the shift lever 3 against the M range switch 54 is not released, and the M range switch 5
Reference numeral 4 denotes a switch which is continuously turned on even during manual shifting (operation mechanism of the M range switch).

On the other hand, on the base plate 6 on the left side of the shift lever 3, there is provided a left vertical wall portion 55, which extends in the front-rear direction and whose upper end projects into the lower surface of the upper plate 9. In the relatively rear portion of the left vertical wall portion 55,
An arc-shaped elongated hole 55a (see FIG. 8) extending in the front-rear direction is formed, and the neutral urging mechanism is formed on the left side surface of the lever body 50 facing the left vertical wall portion 55. At a position below the detent recess 50b, a pressing pin 50c projecting leftward is provided, and the pressing pin 50c protrudes into the arc-shaped long hole 55a, and the shift lever 3 or the lever body 50 is moved. When swinging back and forth, it moves back and forth along the elongated hole 55a.

Then, with the position of the pressing pin 50c when the shift lever 3 is at the neutral position of the M range,
A pair of front and rear shift-up switches 56 and shift-down switches 57 are arranged on the inner surface of the left vertical wall portion 55, that is, on the right side surface on the shift lever 3 side.

Therefore, the shift lever 3 is moved to the M range selection position, and the shift lever 3 and the lever 5
When the shift lever 3 is swung back and forth integrally, the pressing pin 50c also moves back and forth in the long hole 55a of the left vertical wall portion 55, whereby the shift lever 3 is moved forward from the neutral position. When the shift lever 3 is swung from the neutral position to the rear side when the shift lever 3 is swung rearward from the neutral position, the section of the front upshift switch 56 is pressed by the pressing pin 50c. The section of the down switch 57 is pressed by the pressing pin 50c to be turned on (operation mechanism of a shift up switch and a shift down switch). During this time, the M range switch 54 is kept turned on by the M range switch operating mechanism, and the shift up switch 56 or the shift down switch 5 is turned on while the M range switch 54 is on.
When the switch 7 is turned on, the gear shift operation is performed.

Next, the key interlock mechanism will be described. In this embodiment, the key interlock mechanism and the shift lock mechanism are provided under substantially the same configuration. Will be explained.

That is, in the driver's seat of the vehicle on which the shift operation input device 1 is mounted, the steering wheel 6
On the lower surface of a relatively upper portion of the steering column 62 which rotatably supports the steering column 1, an engine start key K is LOCK (shift lock), Acc (accessory), ON (engine electric system on), START (engine). A key operation unit 60 that is operated to be rotated at a plurality of rotation positions such as a start operation is arranged.
As shown by B, it is arranged movably in the axial direction.

When the shift lever 3 of the shift operation input device 1 is shifted from another range selection position to the P range selection position, the lock cable 70 moves in the direction of arrow A (forward for the shift operation input device 1). Conversely, when the shift lever 3 is moved from the P range selection position to another range selection position, the arrow B direction (the shift operation input device 1
Move backward).

The lock cable 70 is connected to the arrow A.
When the key K is moved in the direction, the start key K is moved from the other rotation position by the key operation unit 60 to a position where the key K can be removed.
When the lock cable 70 moves in the direction of arrow B, the start key K can be rotated from the other rotation position to the LOCK position by the key operation unit 60. I cannot do it.

As a result, if the shift lever 3 is not put into the P range selection position, a key interlock that inhibits removal of the start key K is realized, and the start key K
In the state in which the shift lever 3 is removed, a shift lock that prevents the shift lever 3 from swinging from the P range selection position to another range selection position is realized.

The speed change operation input device 1 is provided with a cable moving mechanism for moving the cable in the A and B directions in the key interlock mechanism. This mechanism is, as shown in FIG.
And a plate-like member 81 extending forward from the front surface of the main body 21 of the base member 5 of the lever 3.

The columnar member 81 includes a support shaft (not shown) projecting from the upper surface of the base member 6 and an upper plate 9.
The upper and lower ends are rotatably supported by a boss 82 formed on the lower surface of the base member 6, and extend over the base member 6 and the upper plate 9 and are close to the upper plate 9. An upper extension 83 extending rearward toward the shift lever 3 is provided above the base member 6.
A lower extension 84 extending rightward is provided at a lower portion near the lower end, and the other end of the lock cable 70 is connected to a horizontally extending end of the lower extension 84.

The columnar member 81 is always urged in the clockwise direction in FIG. 2 by a helical spring 85 having both ends locked to the lower extending portion 84 and the base member 6, respectively. The upper extension 83 moves leftward, and the lower extension 84 moves rearward.

When the shift lever 3 is swung from the range selection position other than the P range to the P range selection position, the shift lever 3 is moved rightward in the selection direction along the first communication path G1. The front plate 2 protrudes forward from the base member 5 of the shift lever 3 by swinging.
3 presses the upper extending portion 83 to the right, and as a result,
Upon receiving the pressing force, the columnar member 81 is moved
And the cable 70 moves forward, that is, in the direction A, so that the starting key K can be extracted from the key operation unit 60, and conversely, When the shift lever 3 is swung from the P range selection position to another range selection position, the left side swing in the selection direction along the first communication path G1 causes the front side plate to move. The pressing force against the upper extending portion 83 of the body 23 is removed, and as a result,
The columnar member 81 receives the urging force of the crane spring 85.
Rotates clockwise, whereby the cable 70 moves rearward, that is, in the direction B, so that the starting key K cannot be removed from the key operation unit 60.

In this case, the columnar member 81 for rotating the lock cable 70 between a position where the key K can be removed and a position where the key K cannot be removed is vertically extended, The extension part 83 constituting the input part to which the pressing force of No. 3 is input is arranged at the upper part, and the extension part 84 constituting the coupling part to which the cable 70 is coupled is arranged at the lower part, and are separated from each other. , Lock cable 70
To the front end of the upper plate 9 or the slide sheet 14.
Can be disposed between the key operation unit 60 with good layout without causing interference with other members such as
Since the extended portion 83 to which the pressing force of the shift lever 3 is input is arranged at a position relatively close to the upper plate 9 relatively upward from the pivot point of the shift lever 3, the switch in the aforementioned M range is used. Similarly to the mechanism, the upper extension 83 is pressed and rotated by a large stroke with respect to the swing of the lever 3 at a fixed angle in the select direction.

Therefore, even if a slight dimensional accuracy error occurs in the columnar member 81 and the upper and lower extending portions 83 and 84, the columnar member 81 is surely large due to the swing of the shift lever 3. By rotating the lock cable 70 by the swing width, the lock cable 70 can be reliably moved in the A and B directions by an effective length, and the reliability of the key interlock mechanism is achieved. Then, the mutually different purposes in the two extending portions 83 and 84 are respectively achieved in this way, and both of the purposes are achieved.

The upper and lower ends of the columnar member 81 are supported by the upper plate 9 and the base member 6.
Since these two members 6 and 9 are erected vertically, the support rigidity is enhanced, and the cover 2 is further provided above the upper plate 9. Since the beverage is spilled in the passenger compartment, for example, and accidentally enters the interior through the opening Y of the console X, the beverage travels along the upper surface of the cover 2 because it is disposed below the overlapped area of the consoles 2 and 9. It is possible to avoid such a problem that the columnar member 81 is contaminated by dropping on the base member 6.

On the other hand, as described above, while the start key K is in the LOCK position, the movement of the cable 70 in the direction B is prevented, so that the shift lever 3 is moved from the front P range selection position to the other position. Swinging in the shift direction to the range selection position is restricted. In addition, as shown in FIG. 9, a detection unit 72 for detecting depression of a brake pedal 71, and a detection unit 72
When the depression of the brake pedal 71 is detected by
A solenoid 73 which is excited by an ON signal from the unit 72 is provided. If the brake pedal 71 is not depressed, the solenoid 73 is not turned on. Movement is prevented.

Next, the shift lock mechanism linked to the foot brake will be described. That is, as shown in FIG. 3, the left vertical wall 55 of the shift lever 3 to which the above-mentioned shift-up switch 56 and shift-down switch 57 are attached has a pair of front and rear portions on its inner surface at a relatively forward portion. Are rotatably supported. Each of the lever members 90, 95 is composed of a lower circular body 91, 96 having a rotation support shaft and an extending body 92, 97 extending upward from the circular body 91, 96 and having a predetermined thickness in the width direction. And the above-mentioned circular bodies 91, 96
Gear teeth are formed on the peripheral surface of the.

The gear teeth of the lever members 90 and 95 are meshed with each other, and the intermediate portion of the upwardly extending body 92 of the front lever member 90 is provided on the upper surface of the base member 6. The plunger 99 of the provided solenoid 73 is connected, and when the solenoid 73 is not energized, the plunger 99 pops out, and the upper extending body 92 of the front lever member 90 turns the rotation shaft of the circular body 91. While being swung rearward about the center, the upper extension body 97 of the rear lever member 95 is swung forward about the rotation support shaft of the circular body 96 through the meshing of the gear teeth, On the other hand, when the solenoid 73 is excited,
When the plunger 99 is retracted, the upwardly extending body 92 of the front lever member 90 swings forward, and the upwardly extending body 97 of the rear lever member 95 swings backward.

In this shift lock mechanism, as described above, when the shift lever 3 is at the P range selection position, when the brake pedal 71 is depressed, the solenoid 73 is excited and In addition, when the shift lever 3 is at the N range selection position, when the vehicle speed falls below a predetermined speed, the solenoid 7
3 is configured to be excited. Then, in a state where the upper extension body 92 of the front lever member 90 is swinging rearward, the extension body 92 advances on the first communication path G1 of the shift gate 13 and swings forward. In the state, the extension body 92 retreats from the first communication path G1. On the other hand, when the extension body 97 above the rear lever member 95 swings forward, the extension body 97 13th fifth communication path G
5, the extension body 97 is retracted from the fifth communication path G5 in a state of swinging rearward.

Thus, when the shift lever 3 is at the P range selection position, the solenoid 73 is not excited unless the brake pedal 71 is depressed, so that the plunger 99 continues to protrude and the front lever member 9
0, the upper extension 92 is swung rearward, and as a result, the extension 92 has advanced onto the first communication path G1 of the shift gate 13, so that the shift lever 3 is selected in the P range. 3 and 5 when a select operation is performed from the position.
As shown in FIG. 7, the contact member 24 protruding from the left side surface of the lever 3 comes into contact with the upper extension body 92 of the front lever member 90, thereby moving the shift lever 3 from the P range selection position to the rear R position. Operation to the range selection position side is prevented (P range shift lock).

In the case where the vehicle is turned back and forth during traveling, the solenoid 73 is not excited unless the vehicle speed falls below a predetermined vehicle speed. The upper extension member 97 of the first position is swung forward, and as a result, the extension member 97 has advanced onto the fifth communication path G5 of the shift gate 13, so that the shift lever 3 is moved to the N range selection position. 3 and 5, the contact member 22 protruding from the left side surface of the lever 3, as shown in FIGS.
The upper lever 97 abuts on the upper extension body 97 of the rear lever member 95, thereby preventing the shift lever 3 from operating from the D range selection position side to the front R range selection position side via the N range selection position. (N range shift lock).

In particular, when the former P range shift lock operation is combined with the above-mentioned key interlock operation, the engine cannot be started unless the range is in the P range at the time of starting. After starting the engine, the shift lever 3 cannot be moved to the travel range unless the brake pedal 71 is depressed. As a result, unexpected sudden jumping at the time of starting can be effectively avoided.

In this case, the contact member 24 on the left side of the base member 5 of the shift lever 3 and the upper extending bodies 92 and 97 of the respective lever members 90 and 95 come into contact with each other to select the lever 3. Because operation is blocked,
The impact at the time of the abutment at the time of the shift lock is applied to these lever members 90 and 95, particularly to the upper extending bodies 92 and 97. However, the lever members 90 and 95 are supported by the left vertical wall 55 erected on the base member 6, and the left ends of the upwardly extending bodies 92 and 97 are connected to the vertical wall 55.
However, the lever members 90 and 95 receive the abutting force from behind the left vertical wall 55, that is, the shift lever 3 from the shift lever 3 even though the shock at the time of the shift lock is applied. With the help of the left side opposite to the right side to be applied, the impact force is received by the vertical wall 55, whereby the lever member 9 is received.
It is possible to suppress the problem of deterioration in durability, such as the outward extension of the 0,95 or upper extension bodies 92,97 around the rotation support shaft, and as a result, breakage.

Further, gear teeth are provided on the two lever members before and after the lever member 90 for the P range shift lock and the lever member 95 for the N range shift lock so as to mesh with each other, so that a single solenoid is provided. Since the both lever members 90 and 95 are operated in conjunction with each other at 73, the gearshift operation input device is compared with a case where each lever member 90 and 95 is provided with a dedicated solenoid and individually operated. The number of parts, weight, cost, etc. of one can be reduced.

In addition to the above-described mechanisms, the shift operation input device 1 switches the oil passage of the hydraulic control circuit in the automatic transmission in accordance with the range selected by the shift lever 3. An operation mechanism of the manual valve 26 for achieving the hydraulic supply state for the range is provided. Next, the manual valve operating mechanism will be described.

That is, as shown in FIG. 10, a manual valve 26 is provided in the hydraulic control circuit of the automatic transmission of the vehicle equipped with the shift operation input device 1. In this circuit, an oil pump (not shown)
Is regulated to a predetermined line pressure by a regulator valve, and the regulated predetermined line pressure is supplied to the main line L1. On the other hand, this circuit includes an oil passage L2 to which the operating pressure is supplied in the D range, the M range and the R range, an oil passage L3 to which the operating pressure is supplied in the D range and the M range, and an R range and an N range ( An oil passage L4 to which the operating pressure is supplied in the P-range is provided, and the manual valve 26 is arranged between these oil passages L2 to L4 and the main line L1.

For example, in the forward running range such as the D range or the M range, the manual valve 26 (more specifically, the spool of the valve) moves in the axial direction to the position shown by the solid line in FIG. As a result, the main line L1 and the oil passages L2 and L3 communicate with each other through the valve 26, and the operating pressure is guided to these oil passages L2 and L3. The working pressure is supplied to a hydraulic chamber of a friction element (not shown) such as the above, and the friction element is fastened.

In the non-traveling range such as the N range or the P range, the manual valve 26 moves rightward to the position shown by the chain line in FIG. 10, whereby the oil passage is switched, and the main line L1 and the oil pressure are switched. The passage L4 communicates through the valve 26, and the operating pressure guided to the oil passages L2 and L3 is drained. As a result, the friction element that has been engaged until then is released, and the neutral state is realized. Will do.

The circuit is provided with an oil passage L5 through which the operating pressure is guided in the D range, the M range, and the N range. When the operating pressure is led to the oil passage L5, the operating pressure is fed back to the regulator valve, so that the generated line pressure is reduced as compared with the case of the R range.

The manual valve 26 is configured to move in the axial direction as described above in conjunction with the swing of the shift lever 3 in the shift direction. That is, as described above, the upper extending portion 28 is provided at a position on the front left side of the case member 12 that supports the shift lever 3 so as to swing in the left-right direction.
Is connected to one end of an operation cable 27. At this time, the shift lever 3 and the case member 12 swing integrally as to the swing in the front-rear direction.
When the shift lever 3 is swung forward, the case member 12
Also swings forward, and the operation cable 27 moves forward with the swing. Conversely, when the shift lever 3 swings backward, the case member 12 also swings backward. And the operation cable 27 moves rearward with the swing.

The other end of the operation cable 27 is connected to a manual shaft 102 of a mechanical interlocking mechanism 101 shown in FIG.
When the cable 27 moves forward, the manual shaft 102 rotates clockwise in the drawing,
Conversely, when moving backward, the manual shaft 102
Rotates counterclockwise in the drawing.

The manual shaft 102 is provided near the lower opening of the transmission case 103 by a support bracket 1 bolted to the front side of the case 103 on the front side in the drawing.
A manual plate 106 having a guide groove 105 having a predetermined shape, which will be described later, is attached to the manual shaft 102 while being rotatably supported by the case 04 and a side surface of the case 103 on the upper side in the drawing. The manual plate 106 is configured to rotate integrally with the manual shaft 102.

In this case, the manual plate 10
6, a detent recess 106d... 106d is formed corresponding to each range selected by the shift lever 3, and a detent arm 107 is provided on a support shaft 107 provided at the upper end of the support bracket 104. 108 is rotatably supported, and the roller 109 at the tip of the detent arm 108 is rotated by the detent recess 106d.
06d, and the roller 109 is connected to the support shaft 10
7 is always urged toward the manual plate 106 side by the helical spring 110 wound around, thereby positioning the manual plate 106 for rotation.

Further, a swing arm 112 having a pin 111 engaged with the guide groove 105 of the manual plate 106 is rotatably supported on the support shaft 107. An engagement pin 26a formed at the end of the manual valve 26 is slidably engaged with an engagement groove 113 formed at the lower end of the 112.

The manual plate 106 has P
In the range, the cam body 114 advances from the opening 103a of the transmission case 103 and the cam body 114 at the tip thereof
Lift up along the tapered surface of No. 5 and park pole 1
16 is lifted upward, and a parking rod 118 for engaging the projection 116a formed on the pawl 116 with the parking gear 117 of the output shaft to lock the output shaft is connected.

With this configuration, when the shift lever 3 and the case member 12 are swung in the shift direction by the driver's range selection operation, the operation cable 27 connected to the case member 12 is operated in conjunction therewith. The manual shaft 102 and the manual plate 106 of the mechanical interlocking mechanism 101 rotate in the front-rear direction with respect to the shift operation input device 1. The rotation of the manual plate 106 causes the swing arm 11 to rotate.
The second pin 111 is driven along the guide groove 105 of the manual plate 106, whereby the swing arm 1
12 swings about the upper support shaft 107 of the support bracket 104. The swing motion of the swing arm 112 is applied to the manual valve 26 disposed below the position of the pin 111 by the engagement pin 26 a and the engagement groove 11.
3 through the engagement with the manual valve 26.
Moves to the position for each range, and the oil path of the hydraulic control circuit is switched according to the range selected by the shift lever 3.

Here, not only when the driver swings the shift lever 3 in the shift direction to select a range, but also when the driver swings the shift lever 3 in the shift direction to perform manual shifting within the M range selection position. Also when moving, the manual shaft 102 and the manual plate 106 of the mechanical interlocking mechanism 101 rotate in conjunction with the swing of the lever 3, and the guide formed on the manual plate 106 accordingly. The position of the groove 105 changes.

In this case, the guide groove 105 is used until the shift lever 3 is switched from the P range selection position to the M range selection position via the D range selection position, and reaches the downshift position within the M range selection position. The manual plate 10 is moved so that the pin 111 of the swing arm 112 can be engaged even if the swing arm 112 swings from the front to the rear.
6 is provided so as to extend along the detent recesses 106d... 106d at the peripheral edge of the manual plate 106, and has a linear shape in the first half extending toward the peripheral edge of the manual plate 106 from the start end to the end. 1 engagement groove 10
5a, an intermediate linear second engaging groove 105b extending from the end of the first engaging groove 105a toward the center of the manual plate 106, and a second engaging groove 105b.
The center of rotation of the manual plate 106, that is, the third engagement groove 105c of the rear half portion extending concentrically with the axis O of the manual shaft 102 from the terminal end of the manual shaft 102 is continuous.

When the shift lever 3 is at the selected position of the P range, the pin 111 of the swing arm 112 is
However, as shown by the chain line in the figure, the first engagement groove 105
a at a position corresponding to the position indicated by the symbol a,
When it is at the R range selected position, it is located at a position corresponding to the position indicated by the reference numeral A in the first engagement groove 105a, as indicated by the chain line, and when it is at the N range selected position, it is a solid line in the figure. As shown in FIG.
b, when it is located at the selected position of the D range and at the neutral position of the M range, as shown by the dashed line in the figure, the position shown by the symbol d in the third engagement groove 105c in the rear half. And when it is in the shift-up position of the M range, as indicated by the chain line,
In the third engagement groove 105c, it is located at the position corresponding to the position indicated by the reference symbol o, and when in the M range shift-down position, it is also indicated by the reference character f in the third engagement groove 105c, as also indicated by the chain line. It is located at a position corresponding to the position.

Further, in this case, the distance between the position A of the pin 111 in the P range and the rotation center O of the manual plate 106, and the distance between the pin 1 in the N range and
11 and the rotation center O of the manual plate 106
Are set to be equal to each other, and compared to these distances, the pin 111 in the R range is
Is set so that the distance between the position A and the rotation center O of the manual plate 106 is increased.

On the other hand, the positions D, E, and K of the pins 111 in the D range and the M range are all concentric arc-shaped third engagement grooves 1 with respect to the rotation center O of the manual plate 106.
05c, the distances between these positions D, O, and C and the center O of rotation of the manual plate 106 are all equal. The distance between the position c of the pin 111 in the range and the rotation center O of the manual plate 106 is set to be large.

With the guide groove 105 having such a shape, the pin 111 of the swing arm 112 when the shift lever 3 is swung between the range selection positions is
The manual valve 26 moves to three different distances from the swing center O of the manual plate 106. Accordingly, the manual valve 26 also moves through the engagement between the engagement pin 26a and the engagement groove 113. Move to three different positions
As a result, three types of hydraulic pressure supply states are achieved.

The third engagement groove 105c with which the pin 111 engages when the shift lever 3 is swung to the D range selection position or the M range selection position is used to shift the shift lever 3 within the M range selection position. Even if the swing operation for up or downshift is performed, the pin 111
Is formed so as to form a concentric arc having the same distance from the swing center O of the manual plate 106. Therefore, even if the swing operation is performed while the shift lever 3 is in the M range selection position, the D range Alternatively, the hydraulic pressure supply state for the M range is maintained. Therefore, when the shift lever 3 is swung to the shift-up position, the pin 1
When the position 11 approaches the position in the N range, the manual valve 26 approaches the position for the N range, and the hydraulic supply state approaches the supply state for the N range, and the friction that is fastened when the vehicle travels forward. Problems such as a shortage of the fastening force of the friction element due to a decrease in the operating pressure supplied to the element are avoided, and the shift lever 3 swings from the D range achievement position to the N range achievement position with the same operation. Then, the hydraulic pressure supply state is switched from the D range to the N range.

Further, as described above, the guide groove 105
Is formed in such a shape and does not mechanically separate the shift lever 3 from the cable 27, so that the mechanical structure around the shift lever 3 is not complicated, An increase in the number of parts, weight, and cost can be avoided.

Further, regardless of which of the P range and the N range is selected, the manual valve 26 moves to the same position to achieve the same hydraulic pressure supply state. When the range is selected,
Compared to the case where the manual valve 26 is moved to a different position and then the same hydraulic supply state is achieved in both ranges, the manual valve 2
6 and the shape of the oil passage do not have to be complicated.

For example, the M range is not provided, but the S range and the L range are provided as the forward range in addition to the D range. These range selection positions are arranged adjacent to each other, and the D, S, L A manual valve and the like can also be used with an automatic transmission configured to maintain the same hydraulic pressure supply state in each range, and parts can be shared, thereby contributing to improved productivity. Will be.

Then, the rotation of the manual plate 106 is regulated at each range position by the detent mechanism constituted by the concave portions 106d... 106d of the plate 106 and the detent arm 108.
The swing amount of 2, that is, the movement amount of the manual valve 26 is determined for each range. Further, in the P range, the output shaft is locked, and self-traveling during parking is prevented.

It should be noted that, even if the shift lever 3 is swung within the selected position of the M range, the hydraulic pressure supply state is maintained at the D range or the M range hydraulic supply state. For example, the third engagement groove 105c of the guide groove 105 provided in the manual plate 106 is not formed in an arc shape, and the shift up position or the shift down position is centered on the position at the neutral position of the D range or the M range. As described above, the pin 111 is configured to move back and forth, and even if the manual valve 26 moves at the shift-up position or the shift-down position,
The shape or configuration of the spool of the manual valve 26 and the arrangement of the oil passage may be determined so that the hydraulic pressure supply state does not change.

Further, in this embodiment, the manual valve 26 is configured to be linked with the rotation of the manual plate 106 via the swing arm 112, but the manual valve 26 is moved in the axial direction. When it is not necessary to amplify, the engaging pin 26 a of the manual valve 26 is connected to the guide groove 1 of the manual plate 106.
Needless to say, it may be directly engaged with the 05.

In this embodiment, the shift direction is the front-rear direction and the select direction is the left-right direction.
It goes without saying that the shift direction or the select direction is set independently of such a direction of the vehicle body.

[0113]

According to the first aspect of the present invention, a non-travel range, a forward range, and a reverse range are provided as ranges selected by the swing operation of the shift lever. The traveling range selection position and the automatic transmission range selection position as the forward range are disposed adjacent to each other in the first direction, and the automatic transmission range selection position and the manual transmission range selection position also as the forward range. Are arranged adjacent to each other in a second direction orthogonal to the first direction, and the swing of the shift lever for achieving manual shifting in the manual shifting range is set to the first direction. And, in the end, the direction of swing of the shift lever for switching the range between the automatic shift range and the non-drive range, and the direction of swing of the shift lever for manual shift. But mutually parallel, first both the
Not only that, the operation of swinging the shift lever when switching from the automatic shift range to the non-traveling range, and swinging the shift lever to shift up the gear during manual shifting. One of the operation of causing the shift lever to swing down or the operation of swinging the shift lever to shift down is the same as the above-described swinging operation along the first direction. If the manual valve for selectively switching the state is always operated by swinging the shift lever in the first direction, a shift-up operation or a shift-down operation is performed within the manual shift range selection position. The hydraulic supply state that has been achieved for the forward range approaches the hydraulic supply state for the non-travel range, Susumu operating pressure supplied to the friction element to be fastened during driving is reduced, so that the trouble such as the fastening force of the friction element is insufficient arises.

However, according to the first aspect of the invention, the manual valve operating means is provided. By this operating means, the manual valve is selected not only when the automatic shift range is selected, but also when the manual shift range is selected. ,
Even when the shift lever is swung in the first direction so that the manual shift is achieved in the manual shift range, as long as the shift lever is within the swing range, the hydraulic pressure supply state for the forward range is provided. Therefore, even if the shift lever is swung along the first direction for upshifting or downshifting within the manual shift range achieving position, the hydraulic pressure supply state for the forward range is maintained, whereby In addition, problems such as a decrease in the operating pressure supplied to the friction element that is fastened during forward running and an insufficient fastening force of the friction element can be avoided, and the shift lever can be moved from the automatic shift range attainment position by the same operation. When swinging along the first direction toward the travel range achievement position, the hydraulic pressure supply state is switched from the forward range to the non-travel range.

In this case, the manual valve operating means holds the manual valve in the hydraulic pressure supply state for the forward range, and does not mechanically separate the shift lever and the cable, for example. Therefore, the mechanical structure around the shift lever is not complicated, and increases in the number of parts, weight, and cost can be avoided.

On the other hand, according to the second invention, the manual valve operating means is particularly provided in a mechanical interlocking mechanism provided as a necessary one from the beginning.
Because it is configured not to transmit the swing of the shift lever as a manual shift operation to the manual valve,
No matter how much the shift lever is swung for shifting up or down within the manual shift range attainment position, the manual valve does not move in the axial direction in conjunction therewith, thereby switching the hydraulic supply state. Is surely avoided.

Further, according to the third invention, in particular, the manual valve operating means has a plate member, and the engagement groove of the plate member and the engagement portion of the manual valve are engaged, so that the shift lever When the plate member rotates in conjunction with the swing, the engaging portion moves in the engaging groove, whereby the manual valve is configured to move in the axial direction. When the hydraulic pressure supply state is achieved, the portion of the engagement groove with which the engagement portion engages is formed in a concentric arc shape within the rotation range of the plate member accompanying the swinging of the shift lever during manual shifting. Therefore, within this range, no matter how much the plate member rotates, the manual valve does not move in the axial direction in conjunction with the rotation of the plate member, thereby reliably switching the hydraulic pressure supply state. It is is will be.

Further, by forming the engagement groove of the plate member in such a shape, for example, the automatic transmission range is not provided, and instead of the D range, an S range and an L range are provided as a forward range. The plate member or the machine is arranged between the automatic transmission configured to arrange the range selection positions adjacent to each other and to maintain the hydraulic supply state for the forward range in each of the D, S, and L ranges. It becomes possible to use the automatic interlocking mechanism or the manual valve, and the parts can be shared, which can contribute to an improvement in productivity.

According to the fourth invention, in particular, the parking range and the neutral range are non-traveling ranges, and regardless of which range is selected, the manual valve moves to the same position and the non-traveling range is used. Since the hydraulic pressure supply state is achieved, the manual valve moves to a different position between when the parking range is selected and when the neutral range is selected, and the same hydraulic supply for the non-traveling range is used in both positions. As compared with the case where the state is achieved, the shapes of the manual valve, the hydraulic control circuit, and the oil passage do not have to be complicated.
