Abstract

PURPOSE:To simplify a mechanism which is response at selecting operation of a change lever, by providing a plunger which is elastically pressed against a groove provided in the side face of a member making reciprocating motion at selecting operation of the change lever from the direction normal to the groove. CONSTITUTION:When the selecting operation of a change lever is executed and a detecting body 2 is slid in the direction shown by the arrow A in a cylinder 4, the tip 5c of a responsive plunger 5 receives large reaction force at the location of the step 3c of a V-shaped groove 3, since the tip 5c must cross over the step 3c. Therefore, it can be sensed that the change lever is shifted to a prescribed position from the response of the change lever. When the detecting body 2 is slid in the direction B, the tip 5c of the plunger 5 is smoothly pushed up along the 1st slope 3b of the groove 3 and no crossing-over force, which is required in the initial stage, is not required and the direction of the selecting operation can be sensed by means of a hand.

Description

[Detailed Description of the Invention] Technical Field The present invention relates to a remote control device for a transmission in a vehicle, and in particular, it simplifies the mechanism that applies reaction force to a change lever to reduce the number of manually applied parts, and the control device differs depending on the direction of the select operation. The present invention relates to a remote control device that allows users to respond in a timely manner.

BACKGROUND TECHNOLOGY 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. This method required a click pole for moderation and a coil spring for pressure, which required a large number of parts to achieve the desired response, and the structure was complicated. . In addition, as the structure becomes more complex, more man-hours are required for assembly, and maintainability is also poor.
There were drawbacks such as increased cost.

Purpose The present invention has been made to eliminate the drawbacks of the prior art described above, and its purpose is to provide a V-shaped groove on the side surface of a member that reciprocates at least when a change lever is selected. By providing a plunger that is elastically pressed by a coil spring or the like from a direction perpendicular to the liquid groove, the tip of the plunger is V-shaped no matter which direction the member is moved by the select operation of the change lever. A reaction force is generated by being pushed up from the deepest part of the groove along the slope, simplifying the mechanism that provides a response when selecting the change lever, reducing the number of parts and simplifying assembly. , to improve maintainability and reduce costs. Another purpose is to make it possible to obtain different reaction forces depending on the direction of the select operation by forming a step near the deepest part of one of the slopes forming the single-shaped groove, so that the select position can be adjusted. - Make it easy to distinguish by touch.
That is.

In short, the present invention provides automatic gear shifting in a transmission using an actuating device using electricity, air, etc. as a power source, and in which the actuating device is remotely controlled. A hand-applied plunger is provided on the side surface of a cylinder that slidably accommodates the V-shaped groove and is elastically pressed in a direction perpendicular to the V-shaped groove so as to be slidable; The V-shaped groove has a first groove that slopes flat from the deepest part.
and a shape I in the direction opposite to the first inclined surface.
and a second inclined surface having a step formed near the deepest part, and is characterized in that the reaction force at the time of the selection operation is configured to vary depending on the direction of the selection operation.

The present invention will be explained below based on embodiments shown in the drawings. A transmission remote control device 1 according to the present invention is configured to automatically shift a transmission (not shown) using an actuating device (not shown) powered by electricity, air, etc., and to remotely control the actuating device. In this device, a V-shaped groove 3 is provided on the side surface 2a of the detecting body 2 at the select operation position, which is a member that moves reciprocally when a change lever (not shown) is selected, so that the detecting body can be slid freely. A manual plunger 5 is provided on the side surface 4a of the cylinder 4 to be accommodated, and is configured to be elastically pressed in a direction perpendicular to the HvV-shaped groove 3 so as to be slidable. Further, the V-shaped groove 3 is formed with a first slope 3b sloped flat from the deepest part 3a and in a direction opposite to the first slope 3b, and a step 3C is formed near the deepest part 3a. Second inclined surface 3d
It consists of. The reaction force upon the selection operation is configured to vary depending on the direction of the selection operation.

The cylinder 4 may be attached directly to a part of a change lever of a command unit that generates a command signal for a gear change operation to an actuating device that automatically changes gears of a transmission, or it may be installed separately from a part of the change lever, for example. The detection body 2, which is housed in the dash board of the driver's seat of the vehicle and may be mechanically connected to a part of the change lever by a push-pull cable or the like, is slidably housed in the hollow part 4b of the cylinder 4. It is for electrically detecting the operating position, and has a pair of magnets 6 embedded therein, and a pair of Hall elements 8 on the inner surface of the cylinder 4 facing the magnets.
is fixed. The plunger 5 is attached to the side 4 of the cylinder 4.
It is slidably disposed within a hollow portion 9a of a protruding portion 9 formed to protrude at point a, and its head portion 5a is constantly biased to the left in the figure by a coil spring 10. A retaining ring 11 is attached to one end 5b that protrudes from the protrusion 9 to the right in the figure. The tip 5c of the plunger 5 is connected to the detection object 2.
When is in the position shown in FIG. 1, that is, when the select position is at the neutral position N, it is always in contact with the vicinity of the deepest part 3a of the single-shaped groove 3.

Function The present invention is constructed as described above, and its function will be explained below. When the change lever is moved from the neutral position of the select operation to any select position and the select operation is performed, the detection body 2 slides in the cylinder 4 in either the up or down direction. In this case, for example, if the change lever is operated to select the reverse and first gear positions, the detection body 2 will slide in the direction of arrow A in FIG. Then, the tip 5C of the plunger 5 must first get over the step 3C of the V-shaped groove 3, and therefore receives a large reaction force at this step.

To explain this using the reaction force curve 13 shown in FIG.
As the detection object 2 slides in the direction of the arrow A, the reaction force shows the maximum value 13a of the curve 13 at the initial stage, and as the tip 5C passes through the step 3C, it moves onto the second inclined surface 3d. The reaction force decreases and becomes a normal reaction force at the inflection point 13b. As a result, it is easy to detect that the driver is about to select the reverse and first gear positions by the large response of the change lever. In this case, if the second inclined surface 3d is formed exactly the same as the first inclined surface 3b, the detection object 2 will move from the neutral point N in the direction of arrow A, as shown in FIG. Even in the case of sliding, only a reaction force as shown by curve 14 is obtained, and the feeling of overcoming cannot be obtained.

Next, when the change lever is operated to select, for example, the fourth and fifth gear positions, the detection body 2 slides from the neutral position N in the direction of arrow B, and the tip 5c of the plunger 5 Since it is pushed up smoothly along the first inclined surface 3b of the V-shaped groove 3, the initial overcoming force is not given. A strong reaction force is obtained, and the response is smooth without any feeling of overcoming.
The driver can easily sense that the change lever is about to be operated to select the fourth and fifth gear positions.

Note that in the structure shown in FIG.
3 and a single plunger and a single coil spring can give a reaction force to the selection operation in two directions, and since the step 3c is provided, different reaction forces or responses can be obtained depending on the direction of the selection operation. It is something that can be done. Therefore, it is clear that the number of manually applied parts is reduced and the structure is simplified compared to the conventional example.

Effects Since the present invention is configured and operates as described above, V-shaped grooves are provided on the side surfaces of the members that reciprocate by the selection operation of the change lever, and Since a plunger is provided that is elastically pressed by a coil spring or the like, no matter which direction the member is moved by the select operation of the change lever, the tip of the plunger will move from the deepest part of the figure-7 groove to the inclined surface. It is possible to generate a reaction force by being pushed up by the change lever, and it is possible to simplify the mechanism that obtains the response when selecting the change lever, reducing the number of parts and making it easier to assemble. This has the effect of facilitating maintenance, improving maintainability, and reducing costs.Also, since a step is formed near the deepest part of one of the slopes forming the V-shaped groove, the slope differs depending on the direction of the select operation. This has the effect that a reaction force can be obtained, and the selection position can be easily determined by the touch.
