Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement of a shift device in a power transmission system of a vehicle.

[Prior Art] A shift device for shifting a transmission gear in a vehicle power transmission system uses a vertical shaft that is directly connected to a shift lever to swing two-dimensionally in the X-axis direction and the Y-axis direction. Many of them were mechanical types in which the displacement of the gear 17, etc. was directly switched by swinging displacement in the axial direction and the transverse direction.

However, in recent years, devices have been proposed in which this learning operation is performed via an electrical device.

In this case, two sets of switches are provided, one switch corresponding to positioning by swinging in the vertical axis direction, and the other switch corresponding to positioning by swinging in the horizontal axis direction. These two sets of switch contacts f7i1m
In combination I, several types of shifts corresponding to shift 1 to lever 1 are performed via an electric drive device.

[Problems to be Solved by the Invention] However, such a shift H"&33 has a configuration in which two sets of switches are combined, one corresponding to vertical displacement and the other corresponding to lateral displacement. Naturally, the switch circuits will be multiplexed.

Therefore, this shift device requires extra costs in the design and manufacturing stages, and is also disadvantageous in terms of maintenance and inspection during the use stage.

Furthermore, a considerable amount of space is required to install the 211 switches, and two sets of mechanisms for operating these switches are naturally required, making installation and adjustment cumbersome.

The present invention has been proposed by considering the above-mentioned conventional problems, and by means of a structural ingenuity, the swing displacement operation of the shift lever is converted into a positioning VJ operation that combines reliable movement in both vertical and horizontal directions with little play or rattling. The purpose of this invention is to provide a shift device that requires only one switch.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a vertical shaft connected below the shift lever, a horizontal shaft mounted substantially orthogonally to the vertical shaft 1-, split positioning means for performing positioning by dividing and converting a swinging displacement operation of the vertical shaft in the vertical and horizontal directions by the shift lever into a circumferential displacement and an axial displacement of the horizontal shaft;
A guide mechanism is provided by combining a pin protruding laterally from the vicinity of the mounting portion of the horizontal shaft 1 to the shaft, and a plate with a through groove that is engaged through the pin, and which compensates for and guides the swinging displacement operation of the shift lever. This guide comprises a switch disposed so as to open and close the contact by engaging with the tip of the structure where the pin extends.

[Operations] Therefore, each swinging operation of the shift lever in the vertical and horizontal directions of the shift device of the present invention is performed under conditions where each swing center is different, and the rotational direction of the lateral shaft near the swing center is The conversion is divided into displacement and axial displacement, resulting in compact and reliable operation.

The movement of the pin protruding from the vicinity of the horizontal shaft mounting portion near the center of sliding is similarly compact and reliable.

Furthermore, since this pin protrudes from the mounting portion of the horizontal shaft that is not directly involved in the shift operation, it can be of small diameter.

As a result, the guide mechanism combined with the plate with the through-hole IG for regulating the movement of the pin becomes small. The switch, which opens and closes the contact by engaging with the tip of the pin extending through the groove of the through-grooved plate, is also small and extremely reliable in operation. This is because the pin has a small diameter and its movement is small and reliable.

[Example] Hereinafter, an example of the shift device of the present invention will be described based on the drawings.

A shift device 1 for shifting a transmission gear (not shown) that is part of a power transmission system in a vehicle is provided on the floor on the side of a driver's seat (not shown).

The shift device 1 includes an extended vertical shaft 5 connected to the lower part of the shift lever 3, and a short rectangular cylinder 7 is installed near the center of the vertical shaft 1-5 in the form of dividing the vertical shaft 5 into upper and lower parts. ing.

Inside the rectangular cylinder 7, a horizontal shaft 9 facing in the vehicle width direction is disposed to cross the vertical shaft 5 at a substantially right angle, and is pivotally supported on the rectangular cylinder 7 by a pin 11.

Both ends of the horizontal shaft 9 extend through the left and right side walls of the bracket 13 of the shift device 1 fixed to the floor surface of the vehicle, and are supported by both side walls of the bracket 13 so as to be rotatable and movable. There is. Further, in this case, four annular grooves 17 are cut in one end 15 of the transverse shaft 1-9 in parallel along the outer periphery.

A check ball mechanism 19 with a spring that engages with these annular grooves 17 is attached to the side wall of the bracket 13, and the annular grooves 17 and the check ball mechanism 19 constitute a lateral positioning device 21 for the horizontal shaft 9. There is.

A check ball Bi+M23 with a spring is also attached to the lower end of the vertical shaft 5 extending below the rectangular cylinder 7. And the vertical shaft 5 is the shift lever 3
With this operation, one movement in the vertical direction is made with the horizontal shaft 9 as the center of one movement. At this time, the check ball mechanism 23 at the lower end of the vertical shaft 5 is fitted into an arcuate groove 27 provided in an arcuate plate 25 disposed below.

Therefore, the longitudinal swing of the vertical shaft 5 is performed with the lower end of the vertical shaft 5 limited to the arc of the arcuate groove 27. Further, when the shift lever 3 is swung in the horizontal direction, it oscillates around the ball portion fitted into the arcuate groove 27 of the check ball mechanism 23.

Enlarged recesses 29 with increased depth are provided at the center and both ends of the arcuate groove 27 for positioning these three locations.

That is, an arcuate plate 2 having an arcuate groove 27 with an enlarged recess 29
5 and the check ball mechanism 23 constitute a vertical positioning device 31 for the vertical shaft 5.

This vertical positioning device 31 and the lateral shaft lateral positioning device 21 control the swinging displacement operation of the shift lever 3 in the vertical and lateral directions to the circumferential displacement and axial displacement of the lateral shift V-shift 9. It constitutes a divided positioning means 33 that performs positioning by dividing and converting into two parts.

Further, the tip end 35 of the pin 11 that pivotally supports the lateral shifter 9 in the rectangular cylinder 7 is attached to the bracket 1 as shown in FIG.
It extends through the front wall 37 of No. 3. and pin 1
A through groove 39 in the form of facing comb teeth is cut into the front wall 37 of the bracket 13 so that the vicinity of the front end of the bracket 1 is engaged with the front wall 37 of the bracket 13. That is, a part of the front wall 37 of the bracket 13 is a plate 41 with a through groove, and the groove width is approximately the same as the diameter of the pin 11.

In this state, the pin 11 engages with each part of the through groove 39 in which comb teeth are opposed in accordance with the circumferential and axial displacements of the lateral shift V-shift 9, thereby adjusting each displacement of the lateral shift V-shift 9. regulate. That is, the through-grooved plate 41 and the pin 11 constitute a guide mechanism 43 that supplements and guides the swinging displacement operation of the shift lever 3.

This pin 11 is connected to the front wall 37 of the bracket 13 as described above.
That is, it extends further through the through-grooved plate 41, and its tip 35 engages with the operating lever 47 of the switch 45. The switch 45 is located on the front wall 3 of the bracket 13.
7 through a small bracket 49 at an accurate position.

The contacts are opened and closed according to the movement of the pin 11 engaged with the operating lever 47. In this embodiment, the switch 45
A circuit with 8 circuits and 16 contacts was used.

Each contact point is arranged so as to correspond to each positioning displacement in the circumferential direction and axial direction of the horizontal shaft 9, that is, each longitudinal groove portion of the through-grooved plate 41 shown in FIG. Therefore, the contacts at each shift position are accurately opened and closed by the movement of the pin 11 in accordance with each positioning displacement.

When the shift lever 3 is operated in the shift device 1 configured as described above, first, when the shift lever 3 is swung in the vertical direction (left-right direction in FIG. make a move.

The check ball mechanism 23 at the lower end of the vertical shaft 5 moves while being guided by the arcuate groove 27 of the arcuate plate 25.
It is positioned in an enlarged recess 29 therein.

Next, move shift lever 3 horizontally (left and right in Figure 1) by 1
When it is moved ffi, it swings around the bottom end of the check ball mechanism 23 at the bottom end of the vertical shaft 5 as the center of swing. Then, the horizontal shaft 9 moves in the axial direction and positions in one horizontal direction Vtl2.
1, positioning is performed at four points during the axial movement S1 to ROK.

The vicinity of the extending tip 35 of the pin 11 that pivotally supports the horizontal shaft 9 is compensated and guided by the three through-grooved plates 41 of the front wall 37 of the bracket 13, and is guided in the vertical and horizontal directions of the shift lever 3. The movement of the pin 11 accompanying each positioning and swinging operation is regulated extremely accurately. That is, when the shift lever 3 swings in the vertical and horizontal directions, excessive or insufficient movements and movements that may lead to malfunctions are reliably regulated to enable only accurate shifting operations.

The reliably regulated operation moves the tip 35 of the pin 11 accurately and similarly operates the operating lever 47 of the switch 45 correctly, thereby opening the contact point corresponding to the shift position.
make it move. Therefore, the operating lever 47 of the switch 45 is moved extremely accurately and reliably, so that no excessive force is applied to the contacts or other components of the switch 45. Therefore, the durability and reliability of the switch 45 are maximized.

Further, since the switch 45 is disposed near the front of the front wall 37 of the bracket 13 as described above, the space of the entire shift device including the switch 45 can be made extremely small.

Further, since the member to be engaged with the operating lever 47 of the switch 45 extends from the connecting pin 11 of the horizontal shaft 9 and uses its tip 35, the number of parts is minimized.

The shift device of the present invention is not limited to the one embodiment described above, but can be modified in various ways. For example, in the above embodiment, the pin 11 connecting the horizontal shaft 9 to the rectangular cylinder 7 is extended and used for the guide mechanism 43 and the switch 45, but the penetrating portion of the pin 11 with respect to the horizontal shaft 9 is tapered. engage as

This also makes it possible to almost eliminate looseness between the horizontal shaft 1 and the pin 11.

Further, a pin other than the connecting pin 11 is provided on the horizontal shaft 9 in this vicinity, and this pin is connected to the guide mechanism 43 and the switch 4.
It is also possible to use the connecting pin 11 for the purpose of reducing rattling even more than the connecting pin 11.

[Effect] As is clear from the above description, according to the shift device of the present invention, the vertical and horizontal shift swinging operations of the shift lever cause a circumferential displacement of a single horizontal shaft near the rotation center. Since the position is determined by dividing and converting into axial displacement and axial displacement, the movement is small but extremely clear.

Moreover, as mentioned above, there is almost no play or wobbling due to the structure. Therefore, it is possible to electrically drive a multi-stage shift operation with one set of switches, and the configuration of the switch itself and the circuit is much simpler than in the case of two sets of switches.

Therefore, it is possible to reduce the loss by 1 or more in terms of designing and manufacturing the electric circuit. Furthermore, in terms of use, the failure rate can be significantly reduced, reliability can be improved, and maintenance and inspection can be made extremely easy. Furthermore, the switch itself can be made small, and the switch is mounted close to the bracket surface of the shift device as described above. As a result, the entire shift device including the switch can be made smaller.
