CONSTITUTION:When a change lever 2 is not selectively controlled in any direction, a point end 9a of a plunger 9 engages with the deepest part 4c is a V-shaped groove 4b. And a detecting member 4, in whichever direction it vertically moves, lifts the point end 9a of the plunger 9 by a slope 4b against tension of a coil spring 28, causing reaction force from the plunger 9 to act on the detecting member 4. A remote control device, obtaining action of this reaction force as a similar response in whichever direction the change lever 2 is selectively controlled, enables the construction to be simplified while the number of part items to be decreased.

Description

TECHNICAL FIELD The present invention relates to a remote control device for a transmission in a vehicle, and more particularly to a remote control device in which a mechanism for applying a reaction force to a change lever is simplified to reduce the number of manually operated parts.

BACKGROUND ART Conventionally, various automatic transmissions have been proposed in which a manual transmission is operated by an actuating device powered by air or electricity, and a command unit equipped with a change lever for remotely controlling the actuating device. In the conventional command unit, when applying a predetermined reaction force to a shift/select operation of the change lever to obtain a response, air cylinders are installed on both sides of the member that reciprocates due to the shift or select operation. Because the system required a click ball for moderation and a coil spring for pressing, it required a large number of parts to obtain a response, and the structure was complicated. Ta. In addition, as a result of the complicated structure, many man-hours are required for assembly, and there are also drawbacks such as poor maintainability and high cost.

Purpose The present invention has been made in order to eliminate the drawbacks of the prior art described above, and its purpose is to provide a 7-shaped groove on the side surface of a member that reciprocates by the shift/select operation of a change lever. By providing a plunger that is elastically pressed by air pressure or a coil spring or the like from a direction perpendicular to the groove, the plunger can be moved in any direction by the shift/select operation of the change lever. The tip is inclined from the deepest part of the V-shaped groove.
By creating a reaction force by being pushed up along the surface, we simplified the mechanism that responds to the shift/select operation of the change lever, reducing the number of parts, making assembly easier, and improving maintainability. The aim is to improve the quality of products and reduce costs.

In summary, the present invention provides automatic gear shifting for a transmission using an actuating device using electricity, air, etc. as a power source, and in which the actuating device is remotely controlled. A V-shaped groove is provided in the cylinder, and a manual plunger configured to be elastically pressed in a direction perpendicular to the seven-shaped groove so as to be slidable is provided on the side surface of the cylinder that slidably accommodates the member. , characterized in that the tip of the plunger is pushed up from the deepest part of the 7-shaped groove to the slopes on both sides thereof, thereby applying a predetermined reaction force to the shift/select operation of the change lever. It is.

The present invention will be described below based on embodiments shown in the drawings. A transmission remote control device 1 according to the present invention is a transmission remote control device (not shown) that uses electricity, air, etc. as a power source for a transmission (not shown). This system is designed to automatically shift gears, and the actuating device is remotely controlled.

A detection body 3 for detecting a shift operation, which is a member that reciprocates in response to a shift/selection operation of the change lever 2, and a side surface 3a of a detection body 4 for detecting a selection operation;
4a each have a V-shaped groove 3b.

4b, and V-shaped grooves 3b,
A manual plunger 8.9 is provided which is elastically pressed in a direction perpendicular to 4b and configured to be slidable.

The tips 8a, 9a of the plunger 8.9 extend from the deepest parts 3c, 4c of the V-shaped grooves 3b, 4b to the slopes 3 on both sides thereof.
d and 4d, a predetermined reaction force is applied to the shift/select operation of the change lever 2.

In FIG. 1, the change lever part 10 and the signal part 11 are separated from each other and are mechanically connected by a push-pull cable 12.13. The change lever part 10 includes a case 13, a shift plate 14 that is slidably disposed within the case and is orthogonal to each other, a select plate 15, and a guide plate 16 that engages with these.
The guide plate 16 has a hole 16a in the center, and the ball portion 2a of the change lever 2 is engaged with the hole. The guide plate 1 is attached to the shift plate 14.
A downward groove 14a into which the change lever 6 is slidably fitted and an elongated hole 14b which allows movement of the change lever 2 in the select direction are formed, and a guide plate 16 is slidably fitted into the select plate 15. an upward groove 15a that allows the change lever 2 to move in the shift direction;
5b is formed. One end of the push-pull cable 12 is connected to the shift plate 14 by a pin 18, and the other end of the push-pull cable is connected to one end 3e of the detection body 3 by a pin 19. Further, one end of the push-pull cable 13 is connected to the select plate 15 by a pin 20, and the other end of the push-pull cable is connected to one end 4e of the detection body 4 by a pin 21. The push-pull cables 12,13 are each attached to the case 13 by hollow bolts 22,23, respectively.

The signal section 11 consists of a cylinder 5 for obtaining a response for a shift operation and a cylinder 6 for obtaining a response for a select operation, and a sub-cylinder 25 is formed protruding from the side surface 5a of the cylinder 5. , hollow part 25a of the sub-cylinder 25
A plunger 8 is slidably housed in the hollow portion, and an air port 25b for sucking and discharging air is formed in the hollow portion.

A protruding portion 26 is formed on the side surface 6a of the cylinder 6, and a plunger 9 is slidably housed in a hollow portion 26a of the protruding portion. It is pressed and biased. Note that detection object 3
A pair of magnets 29 are embedded in the side surfaces of the cylinder 5, and a pair of Hall elements 30 are fixed to the inner surface of the cylinder 5.

Further, a pair of magnets 31 are embedded in the side surface of the detection body 4, and a pair of Hall elements 32 are fixed to the inner surface of the cylinder 6.

Note that what is shown by the imaginary line in FIG. 1 is the regulation plate 35 for the change lever 2 fixed to the upper part of the case 13,
A so-called H-shaped guide groove 35a is formed in each of the regulating plates.

Function The present invention is constructed as described above, and its function will be explained below. As shown in FIG. 1, a transmission remote control device 1 according to the present invention is separated into a change lever part 10 and a signal itt, which are mechanically connected by a push-pull cable 12.13. Therefore, a more compact change lever part 1
0 is installed in the driver's seat of the vehicle (not shown), and the signal section 1
1 can be stored in a dash board (not shown). Accordingly, the space around the driver's seat becomes wider, the degree of freedom in design increases, and the ease of getting in and out of the vehicle is improved.

Next, to explain the shift operation and selection operation of the remote control device 1 of the transmission, first, when the change lever 2 is rocked in the left and right direction in FIG. The plates 16 reciprocate in the same direction, which causes the select plate 15 to reciprocate in the same direction. Therefore, the push nibble cable 13 reciprocates, and the detecting body 4 in the cylinder 6 connected thereto reciprocates in the vertical direction in FIG. 3. In this case, if the change lever 2 is not operated in any direction from the position shown in FIG. 1, the tip 9a of the plunger 9 is engaged with the deepest part 4C of the V-shaped groove 4b. When the detection body 4 moves in either direction, the tip 9a of the plunger 9 is pushed up by the slope 4d against the force of the coil spring 28. A reaction force acts. This reaction force acts on the change lever 2 because the shape of the V-shaped groove 4b is the same in the vertical direction in the figure.
The same response will be obtained no matter which direction is selected.

Therefore, it is no longer necessary to provide a pair of plungers and coil springs on both sides of the detection body 4 as in the conventional case, and the structure can be simplified and the number of parts can be reduced.

Next, in FIG. 1, when the change lever 2 is operated to shift in the vertical direction, the guide plate 16 reciprocates in the same direction, thereby causing the shift plate 14 to reciprocate in the vertical direction. As a result, the push-pull cable 12 reciprocates, and the detection body 3 in the cylinder 5 connected thereto reciprocates in the vertical direction in FIG. 2. In this case, when the change lever 2 is in the neutral position, the tip 8a of the plunger 8 is located at the deepest part 3C of the V-shaped groove 3b, and air at a predetermined pressure is supplied to the hollow part 25a from the air port 25b. The air pressure acts on the plunger 8, and the plunger is always pressed and biased to the left. Therefore, no matter which direction the detection object 3 tries to move up or down by the push-pull cable 12, the tip 8a of the plunger 8 is pushed up by the slope 3d, so that a reaction force is exerted from the plunger on the detection object. . In the case of a shift operation, the shift operation is completed when the detection body 3 moves up or down and the magnet 29 comes to a position facing either Hall element 30. is discharged, and the pressing force of the plunger B against the detection body 3 disappears. Therefore, the response to the change lever 2 disappears, and the driver can sense that the shift operation has been completed.

Even in the cylinder 5 which provides a shift response in this way, there is no need to provide a pair of plungers and sub cylinders 25 on both sides of the upper and lower sides of the detection body 3 as in the conventional example, and the structure thereof is simplified.

In addition, in the above, the V-shaped grooves 3b and 4b of the detection body 3.4
In Figs. 2 and 3, the grooves have been explained as having the same shape in the vertical direction, but this is not limited to having the same shape. It goes without saying that the response during the shift operation and selection operation can be changed.

Effect Since the present invention is configured and operates as described above, a V-shaped groove is provided on the side surface of the member that reciprocates by the shift/select operation of the change lever, and air is supplied from a direction perpendicular to the groove. Since a plunger is provided that is elastically pressed by pressure or a coil spring, the tip of the plunger does not move from the deepest part of the V-shaped groove no matter which direction the member is moved by the shift/select operation of the change lever. Since a reaction force is generated by pushing up along the slope, the mechanism that obtains the response during shift/select operation of the change lever can be simplified, and the number of parts can be reduced. This has the effect of facilitating assembly, improving maintainability, and reducing costs.
