Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a remote control device for a transmission in a vehicle, and in particular, it smoothes the movement of a change lever in the select direction and provides a tactile response at each select position. The present invention relates to a remote control device in which the change lever is always held at the center position when the user's hand is removed from the control device, and furthermore, the change lever is made difficult to move to a specific select position, thereby improving operability.

Conventionally, as shown in Fig. 1, an electric signal for gear shift operation is supplied to an actuating device operated from the driver's seat to shift the gear of the engine transmission, which is located far from the driver's seat of the vehicle. In a transmission remote control device 31, a sliding hole 33a of a cantilevered bearing 33 protrudes from one side of a casing 32 fixed to a vehicle body (not shown).
The guide rod 3 to which the change lever 34 is fixed
Since the rod 5 is slidably and rotatably inserted and the rod is supported in a cantilevered state, there is a disadvantage that the movement of the change lever 34 in the selection direction is not smooth. If an attempt is made to make the stroke longer, the entire device becomes longer, and the length of the engagement between the guide rod 35 and the bearing 33 becomes shorter, resulting in a further deterioration in operability. In addition, in the conventional example, there was no positioning mechanism for operating the change lever in the select direction, so when the change lever was operated in the select direction, it was determined by the response whether or not it was set to the select position or not. The drawback was that I couldn't do it. Furthermore, since the guide rod that slides in the select direction did not have a spring action, when you let go of the change lever, the change lever would stop at that position, making it difficult to find where the change lever would be the next time you move it. It is difficult to understand, and there is no tactile response when the change lever moves to a specific select position such as the reverse position, making it easy to make operational errors.

The present invention has been made to eliminate the above-mentioned drawbacks of the prior art, and its purpose is to remotely control the transmission of an engine by means of an electro-pneumatic or hydraulic actuation device. The object of the present invention is to improve the operability of a remote control device in which a change lever slides in a select direction and swings in a direction perpendicular to the select direction, that is, in a shift direction. To ensure that the guide rod to which the change lever is fixed is supported with an extremely long fitting length, so that the change lever can be operated smoothly in the selection direction at any position. It is in. Another object is to make the remote control device more compact by making the overall length of the remote control device shorter even though the stroke of the change lever in the select direction is longer. Another purpose is to provide a sense of moderation in the operation of the change lever in the select direction, so that when the change lever is set at each select position, it can be felt by the response, thereby improving the operation feel. The aim is to improve the Another purpose is to keep an equal spring force constantly acting on both ends of the guide rod that slides in the select direction, so that when the change lever is released, the change lever is held in the central position. The purpose is to make the starting position clear for the next operation. Another purpose is to apply a larger resistance force when the change lever moves to a specific select position, thereby making it easier to determine the select position based on the feel of the change lever, thereby improving gear shifting. This is to prevent operational errors from occurring.

In short, the present invention provides an electric signal for shifting an engine transmission disposed far from the driver's seat, which is operated at the driver's seat to provide an electric signal for shifting the engine transmission.

A fitting portion is formed with one end fixed to the guide rod and having two parallel surfaces that can be slidably fitted into the slit of the guide cylinder, and an actuator for operating a select position detection switch is protruded from the side surface. and a pair of neutral compression springs interposed between the ends of the pair of hollow bearings and both ends of the guide rod so as to press and urge the guide rod with equal force from both sides. and a selection confirmation compression spring which is interposed together with at least one of the pair of neutral compression springs and which applies a greater resistance force to the guide rod when moving to a specific selection position. The present invention is characterized in that the setting to the select position and the transition to the specific select position can be confirmed by the feel of the change lever.

The present invention will be explained below based on embodiments shown in the drawings. 2 and 3, the transmission remote control device 1 according to the present invention is installed in a position far from the driver's seat (not shown), for example, for an engine (not shown) disposed in the rear of the vehicle. This device is designed to give an electrical signal for gear shifting to an electro-pneumatic or hydraulic actuating device (not shown) for shifting the transmission (not shown) of the vehicle, and is operated from the driver's seat. It's becoming like that.

The housing 2 is fixed to a part of the vehicle body (not shown), and has a rectangular shape as shown in the figure, for example, and has a so-called H-shaped groove 3 in its upper opening 2a.
A speed change guide plate 3 having a portion a is fixed thereto. Three select position detection switches 4 capable of detecting, for example, three select positions are arranged on the upper part of one side wall 2b, and the other side wall 2b
At the bottom of c, there are three shift position detection switches 5 that can detect, for example, three shift positions.
is installed.

A pair of hollow bearings 6, 6 are fixed to opposing side walls 2c, 2d of the casing 2 in a concentric manner facing each other, and sliding holes 6a, 6a are formed in the center, respectively. .

The guide cylinder 8 is rotatably supported with both ends 8a, 8a restrained in the axial direction by the enlarged holes 6b, 6b of the pair of hollow bearings 6, 6, and the hollow bearing 6 is provided in the center of the guide cylinder 8. A through hole 8b having the same diameter as the sliding hole 6a is formed. Further, a slit 8c having a predetermined width is formed in the upper part and is elongated in the axial direction, and an actuator 8d for operating the shift position detection switch 5 is integrally extended in the lower part.

The guide rod 9 is slidably fitted into the guide cylinder 8 and the hollow bearing 6.

The change lever 10 has a threaded portion 10a formed at one end fixed to the longitudinal center of the guide rod 9, and has a parallel threaded portion 10a that can be slidably fitted into a slit 8c of the guide cylinder 8. A fitting portion 10b having two surfaces S is formed, and the change lever 10, the guide rod 9, and the guide cylinder 8 are restrained from each other in the direction of rotation by the fitting portion 10b and the slit 8c. , configured to be slidable only in the axial direction. An actuator 10d for operating the select position detection switch 4 is protruded from one side of the change lever 10.

Further, in a part of the outer periphery of the guide cylinder 8, there is a hollow chamber 14 for accommodating a ball 12, which is an example of a select position confirmation member, and a spring 13 for biasing the ball.
is formed. On the other hand, the guide rod 9 has a select position confirmation recess 9 in which a ball 12 is pressed by a spring 13 and engaged with the outer peripheral surface facing the hollow chamber 14 of the guide cylinder 8 to obtain moderation.
A is formed at three locations.

Furthermore, in the present invention, hollow portions 9b are formed at both ends of the guide rod 9, and an equal force is applied to the guide rod from both sides between the ends 6c of the pair of hollow bearings 6 and both ends of the guide rod 9. A pair of neutral compression springs 15, 15 are interposed so as to be biased by the guide rod 9 when moving to a specific select position. A compression spring 16 for selection confirmation is interposed to provide a larger resistance force.

The setting of the change lever to each select position and the transition to a specific select position can be confirmed by the response of the change lever.

The present invention is configured as described above, and its operation will be explained below. Change lever 10
is integral with a guide rod 9, and the guide rod 9 is supported with a very long fitting length across the guide cylinder 8 and the through hole 8b and sliding hole 6a of the pair of hollow bearings 6, 6, respectively. This fitting relationship does not change at all no matter what position the guide rod moves, so it always slides smoothly, and the change lever 10 can be operated smoothly in the selection direction. In this case, the fitting part 10 of the change lever 10
b slides smoothly within the slit 8c of the guide cylinder 8. When the actuator 10d reaches one of the positions of the select position detection switch 4, an electric signal is output from the switch, and the transmission actuator is activated to move the transmission select shaft to the specified position. let

Next, when the change lever 10 is operated to shift, the fitting portion 10b is inserted into the slit 8 of the guide cylinder 8.
Since the guide cylinder is rotated via the shift lever 10c, the change lever 10 and the guide cylinder 8 rotate together, and when the actuator 8d reaches the position of one of the shift position detection switches 5, the switch is activated. An electrical signal is issued from the transmission unit, which activates the transmission actuator to move the transmission shift fork to the position where one of the gears is selected, completing the shift operation.

Further, in the selection operation of the change lever 10, when the guide rod 9 slides and reaches a predetermined selection position, one of the recesses 9a of the guide rod comes to a position facing the ball 12.
The ball 12 engages with the recess, and the change lever 1
0 conveys a sense of moderation, and the change lever 10 indicates that selection has been completed at any select position.
You can clearly feel the response, and the selection operation feels better. Also guide rod 9
Since the switch 4 always stops at the same position with high precision at each select position, the operation of the select position detection switch 4 is also made more stable.

Furthermore, in the present invention, when the change lever 10 is released, the compression spring 15 presses the guide rod 9 toward its center with equal force from both sides, so that it automatically returns to the neutral position as shown in FIG. and remains stationary. For example, when the change lever 10 is selectively operated to the left in the figure from the neutral position shown in FIG.
5 extends and the pressing force gradually decreases, so the change lever 10 becomes harder to operate as the amount of displacement increases. Finally, the end 9c of the hollow chamber 9b of the guide rod 9 comes into contact with one end 16a of the selection confirmation compression spring 16 and begins to compress the compression spring 16 as well, so the resistance of the spring increases rapidly and this This is felt through the change lever 10,
The selection operation of the change lever 10 can be made heavy only when the leftmost selection position, for example, the reverse gear selection position, is selected.

Note that it is clear that the compression spring 16 can also be interposed within the compression spring 15 on the right side, if necessary.

Since the present invention is constructed and operates as described above, it is a remote control device that remotely controls the speed change of an engine transmission using an electro-pneumatic or hydraulic actuating device. , the change lever slides in the select direction,
Moreover, the operability of a remote control device having a structure that swings in a direction perpendicular to this direction, that is, in the shift direction, can be improved, and in particular, the guide rod to which the change lever is fixed is supported with an extremely long fitting length. Therefore, it is possible to obtain the effect that the change lever can be operated smoothly in any position at any time. Further, even if the stroke of the change lever in the select direction is made long, the overall length of the remote control device can be shortened, thereby achieving an effect of making it more compact. Furthermore, since it is possible to give a sense of moderation to the operation of the change lever in the select direction, when the change lever is set at each select position, this can be felt by the response, improving the operation feeling. It has the effect of being Also, since equal spring force is always applied to both ends of the guide rod that slides in the select direction, when you release your hand from the change lever, the change lever will be held in the center position, and next This has the effect of making the starting position clear during operation. Furthermore, when the change lever moves to a specific select position, greater resistance is applied, so
Since the select position can be easily determined based on the response of the change lever, it is possible to prevent mistakes in gear change operation.
