Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a manual shift operation device for an automatic transmission that is manually operated via a shift lever to change the range of the automatic transmission.

[Prior Art] In an automatic transmission installed in a car, a shift lever (also called a select lever) placed inside the vehicle is operated by the driver to select a shift position, and the shift position is selected from forward range to neutral range. Range, reverse range, parking range, etc. can be selected.

As shown in FIG. 7, the conventional floor-type shift lever 10 is designed to be rotated in one direction in the direction of arrow A using a shaft 12 as a fulcrum.
The rotational motion at this time is mechanically transmitted to the automatic transmission as linear motion via cables and rods. (Japanese Unexamined Patent Publication No. 59-206918, etc.) Also, as shown in FIG. 8, the shift lever 10 is
A model in which the shift lever 10 can be moved in two directions, vertically and horizontally in the figure, has also been put into practical use, but in this type, the transmission is transmitted to the automatic transmission only when the shift lever 10 is moved in the vertical direction in the figure. It is only the movement when moving.

Furthermore, as shown in FIG. 9, a shift lever 10 that is movable in two directions along a substantially H-shaped guide path 16 has been proposed.
This is a combination of electric and mechanical systems, and only the movement in one direction is mechanically transmitted to the automatic transmission (Special Publications No. 48-
No. 211).

In this way, in the conventional manual gear shift operation device for automatic transmission, what is mechanically transmitted to the automatic transmission is:
It is only a movement of the shift lever 10 in one direction.
This is because the manual valve of the hydraulic control device provided in the automatic transmission is a spool valve that is moved in one direction to switch ports, and the shift lever 10 is mechanically connected to this manual valve. .

For this reason, in conventional manual shift operating devices for automatic transmissions, shift positions are limited to those aligned in one direction, resulting in a problem in that the degree of freedom in design is low.

[Problems to be Solved by the Invention] In view of the above, the present invention provides a manual shift operation device for an automatic transmission that can increase the degree of freedom in design by making it possible to arrange shift positions in multiple directions. With the goal.

[Means for Solving the Problems] In the manual shift operating device for an automatic transmission according to the present invention, there is a shift lever that is movable in multiple directions, and a movement path of the shift lever between shift positions arranged in multiple directions. a limiting means for limiting the
The present invention is configured to include a conversion means that mechanically converts movement of the shift lever in multiple directions into movement in one direction and transmits the movement to the automatic transmission.

[Operation] In the present invention having the above configuration, movements of the shift lever in different directions when moving between shift positions are transmitted to the automatic transmission as movements in one direction.

[Embodiment] FIGS. 1 and 2 show an embodiment of a manual gear shift operation device for an automatic transmission according to the present invention. In the figure, the direction of arrow BC is the front-rear direction of the vehicle interior, and the direction of arrow DE is the left-right direction of the vehicle interior.

As shown in FIG. 1, the shift lever 20 is provided with a ball joint 22 at its lower end, and a shift lever 24 is attached to its upper end.
The ball joint 22 consists of a ball portion 22A formed at the lower end of the shift lever 20 and a case member 22B that supports the ball portion 22A.
B is fixed to the housing 26. Thereby, the shift lever 20 is rotatable in the radial direction with respect to the axis using the ball joint 22 as a fulcrum. That is, when the shift lever 20 is viewed from above, the shift knob 24 is movable in all directions.

Note that a tightening margin is set for fitting the ball portion 22A and the case member 22B so that the shift lever 20 can stand on its own without being supported by others.

A first detent plate 28 is fixed to the upper part of the housing 26. The first detent plate 28 has an elongated hole 30A extending in the left-right direction of the vehicle interior and a long hole 30A extending parallel to each other from both ends and the center of the elongated hole 30A toward the front and rear of the vehicle interior. A guide passage 30, which is a restricting means, is formed from the six elongated holes 30B to 30G. Guide passage 3
A shift lever 20 is inserted through the shaft 0. As a result, the movement direction of the shift lever 20 is limited to two directions: the front-rear direction of the vehicle interior and the left-right direction of the vehicle interior, and the path of movement is also restricted.

A second detent plate 32, which is a converting means, is arranged below the first detent plate 28. The second detent plate 32 is guided by a guide rail 33 fixed to the housing 26 and is movable in the longitudinal direction of the vehicle interior. A long hole 34 is bored in the second detent plate 32. The long hole 34 is arranged at an angle with respect to any of the long holes 30A to 30G. The shift lever 20 is inserted into the elongated hole 34.

The positional relationship between the elongated hole 34 and the shift lever 20 is as shown in FIG. That is, the shift lever 20 is located at the left end of the elongated hole 30A (hereinafter referred to as position M1) in the first detent plate 28.
That's what I say. ) When located in the elongated holes 30B and 30C, it is located at the left end of the elongated hole 34 in the left-right direction of the vehicle interior (position on line F in FIG. 2). In the first detent plate 28, the central part of the elongated hole 30A (hereinafter referred to as position M2), the elongated hole 30D, and the elongated hole 30
When the shift lever 20 is located at position E, the shift lever 20 is located at the center of the elongated hole 34 in the left-right direction of the vehicle interior (see Fig. 2G).
line position). In the first detent plate 28,
When located at the right end of the elongated hole 30A (hereinafter referred to as position M3), the elongated hole 30F, and the elongated hole 30G, the shift lever 20 is located at the right end of the elongated hole 34 in the left-right direction of the vehicle interior (position M3). Figure 2 H line position).

Further, the shift lever 20 is arranged in the first detent plate 28 at the positions M1, M2,
M3, and the ends of the long holes 30B to 30G on the side away from the long hole 30A (as shown in FIG. 1 corresponding to each long hole 30B to 30G, positions L, 2, and D, N, R, P), it is set so as to come into contact with the front hole wall 34A or rear hole wall 34B of the elongated hole 34.

The length of the elongated hole 34 in the longitudinal direction of the vehicle interior is determined by the length of the elongated hole 34 when the shift lever 20 is operated to move from one position to the next position in the longitudinal direction of the vehicle interior (hereinafter, the movement operation in this direction is referred to as a shift operation). 34, the length is set to such a length that it comes into contact with the front hole wall 34A or the rear hole wall 34B when the hole is moved a distance S through the hole 34.

The inclination of the elongated hole 34 is such that when the shift lever 20 is operated to move in the left-right direction of the vehicle interior (hereinafter, the operation to move in this direction is referred to as a select operation), the shift lever 20 moves toward the front hole wall 34A or the rear hole. It is provided to move the front hole wall 34A or the rear hole wall 34B in the longitudinal direction of the vehicle interior by the force in the longitudinal direction of the vehicle interior of the force that presses the wall 34B in the left-right direction of the vehicle interior. This angle of inclination is such that when the shift lever 20 is selectively operated from a certain position to the next position in the first detent plate 28, the shift lever 20 moves toward the front hole wall 34A or the rear hole wall 34A.
If you move without being separated from 4B (2nd
(as indicated by the dashed arrow in the figure), the front hole wall 3

It is set at an angle that can be moved 2S. At this angle of inclination, the shift lever 20 is selectively operated in relation to the length of the elongated hole 34 in the longitudinal direction of the vehicle interior, and the front hole wall 34A or the rear hole wall 34B is selected.
When it moves so that it comes into contact with the rear hole wall 34B or the front hole wall 34A after once separating from the
The rear hole wall 34B or the front hole wall 34A can be moved a distance S in the longitudinal direction of the vehicle interior.

As shown in FIG. 1, the upper end of a lever 36 is pivotally supported at the end of the second detent plate 32 on the front side of the vehicle compartment. This lever 36 has a shaft 38 fixed to its intermediate portion, and the housing 26
It is pivoted on. One end of a push-pull cable 40 is locked to the lower end of the lever 36.

The other end of the push-pull cable 40 is locked to one end of a lever 42. The other end of the lever 42 is pivoted to one end of a shaft 44.
The shaft 44 is pivotally supported by a valve body of a hydraulic control device for an automatic transmission (not shown), and a manual valve lever 46 is pivotally attached to the other end.
The manual valve lever 46 has six notches 48A to 48F continuously formed on the arcuate outer periphery of one end. A roller 52 pivotally supported by one end of a leaf spring-like detent spring 50 is fitted into one of the notches 48A to 48F, depending on the swing angle of the manual valve lever 46. . The other end of the detent spring 50 is attached to the valve body (not shown), and urges the roller 52 in the direction of pressing it against the manual valve lever 46. As a result, the manual valve lever 46 can be moved with moderation to the notches 48A to 48A.
It is possible to stop at six positions corresponding to 48F.

A pin 54 is pivotally attached to the manual valve lever 46, and this pin 54 is connected to a pair of flanges 58 formed at one end of the manual valve 56.
It is located between 60 and 60. The other end of the manual valve 56 is inserted into the valve body (not shown), and when moved in the direction of the arrow, ports are switched inside the valve body to select a hydraulic circuit for a predetermined speed range. is being used. That is, when the roller 52 is fitted into the notch 48A, the manual valve 56 is moved to the deepest position inside the valve body, and in this state, the L range hydraulic circuit is selected. When the manual valve range 46 is oscillated from this state and the roller 52 is fitted into the notch 48B, the pin 54 that is oscillated together during this oscillation presses the flange 58 and moves the manual valve 56. , In this state, the 2-range hydraulic circuit is selected. Thereafter, the hydraulic circuits of the D range, N range, R range, and P range are sequentially selected in the same manner. Furthermore, when the manual valve lever 46 is swung in the opposite direction to the above,
The pin 54 presses the flange 60 to move the manual valve 56 in the opposite direction.

Note that when the P range hydraulic circuit is selected, a parking lock mechanism (not shown) operates in conjunction with the swinging of the manual valve lever 46 to lock the output shaft of the automatic transmission (not shown). has been done.

Next, the operation of this embodiment will be explained.

First, a case where the shift lever 20 is operated and the shift position is sequentially changed in the direction of L→2→D→N→R→P will be described with reference to FIG. 3.

When the L range hydraulic circuit is selected, the shift range 20 is shifted to the guide passage 3 of the first detent plate 28, as shown in Fig. 3 No. 1.
0 and is located at position L. Also,
The shift lever 20 has a second detent plate 32
It is located at the lower left corner of the elongated hole 34. In this state, as described above, the manual valve 56 has been moved to the deepest position inside the valve body.

When the shift position is changed from position L to position 2, the shift lever 20 passes through position M1 as shown at No. 2 in FIG. 3 during the shift operation. shift lever 2
0 moves in the elongated hole 34 until it reaches position M1, the second detent plate 32 is not moved and the manual valve 56 remains in the L range hydraulic circuit selection. shift lever 2
After passing through position M1, the second detent plate 32 is moved in the direction of arrow B by pressing the front hole wall 34A of the elongated hole 34 to reach the state shown in No. 3 in FIG. At this time, the movement of the second detent plate 32 causes the lever 36 to swing in the direction of arrow J, and the lever 42 to swing in the direction of arrow J via the push-pull cable 40. The valve lever 46 is also swung in the direction of arrow J. As a result, the manual valve 56 is moved as described above, and the two range hydraulic circuits are selected.

When the shift position is changed from position 2 to position D, the shift lever 20 is shifted to position M1 as shown in Figure 3 No. 4, and then selected and moved to position M1 as shown in Figure 3 No. 3. It reaches position M2 as shown in Figure 3, and is further shifted to position D as shown in Figure 3, No. 6. The second detent plate 32 is not moved in the process from No. 3 to No. 4 in Figure 3 because the shift lever 20 only moves within the elongated hole 34, but it does not move from No. 4 to No. 5 in Figure 3. In the process, the shift lever 20 touches the front hole wall 34A.
is pushed in the left-right direction of the vehicle interior, and is moved by the component force in the vehicle longitudinal direction at this time. Therefore, the D range hydraulic circuit has already been selected at position M2 shown in No. 5 in Figure 3, and the second detent plate 32 is not moved during the process from No. 5 to No. 6 in Figure 3. .

The hydraulic circuits for each range are selected as shown in No. 7 to No. 13 in FIG. 3 below.

In Figure 4, the shift position is P→R→N→
A case is shown in which the direction is sequentially changed from D to 2 to L. As is clear from a comparison with FIG. 3, the positional relationship between the elongated hole 34 and the shift lever 20 is the same in both figures at positions L, 2, D, N, R, and P, but at positions M1, This positional relationship is different for M2 and M3, and there are cases where the ranges of the selected hydraulic circuits are also different (Nos. 2, 7, and 12). This corresponds to the fact that in actual operation, the shift position is not changed sequentially as shown in FIGS. 3 and 4. That is, for example, when the shift lever is changed directly from position L to position P, the shift lever does not pass through positions 2, D, N, and R, so even in this case, the hydraulic circuit changes to positions 2, D, N, and R. It is designed so that the hydraulic circuit changes to the P range after going through the range, and no matter what happens to the shift lever, the shift position L, 2, D, N, etc.
For R and P, the hydraulic circuit always selects a range that correctly corresponds to the shift position. This is possible because, as explained in FIG. 2, when the shift lever 20 is operated to select, the second detent plate 32 is moved a distance S even if the amount of operation is the same. This is because there are cases where it is moved by a distance of 2S and cases where it is moved by a distance of 2S.

In this way, in this embodiment, the shift positions arranged in two directions can be changed by the shift operation and the selection operation, so the stroke of the shift lever 20 in the longitudinal direction of the passenger compartment can be reduced, which saves space. And the degree of freedom in design increases.

Further, since the movement locus of the shift knob 24 can be concentrated in a narrow range, the distance between the shift knob 24 and the driver is shortened, and the operability of the shift lever 20 is improved.

Furthermore, since the shift pattern is based on the H-shape similar to that of a manual transmission, it is possible to make the shift pattern the same as that of a manual transmission, and it is possible to reduce the sense of incongruity between the two.

Furthermore, since the attitude of the shift lever 20 clearly changes at each position, the position of the shift lever 20 can be easily determined visually.

In the above embodiment, the first detent plate 28 is placed at the top and the second detent plate 32 is placed at the bottom, but the vertical relationship between the two may be reversed.

5 and 6 show the shape of the guide passage 30 of the first detent plate 28 and the hole 62 formed in the second detent plate 32, respectively, which can make the shift pattern different from that of the previous embodiment.
(corresponding to the elongated hole 34 of the previous embodiment) is shown.

[Effects of the Invention] As explained above, in the manual shift operation device for an automatic transmission according to the present invention, shift positions can be arranged in a plurality of directions, so that the degree of freedom in design is increased.
