Description

[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to an actuator that operates each pedal in a vehicle during vehicle testing and the like.

B. Summary of the invention This invention relates to an operating device for operating the pedals of a vehicle, in which an arm that is swung by an actuator is attached to a rod connected to the pedal so that it can swing freely in the axial direction of the rod. The arm and rod are brought into contact with each other by a stopper that can be fixed at any position on the rod, and the pedal is depressed by the swinging of the arm, making it easy to install the actuator in the vehicle. This simplifies the installation work and adjustment during the return operation, and since the arm can move forward by leaving engagement with the stopper during the return operation, the return operation of the rod can be performed naturally and effortlessly. I made it.

C. Prior Art In vehicle tests, etc., an actuator is installed inside the vehicle, each pedal such as an accelerator pedal or a clutch pedal is connected to the actuator, and these pedals are operated by operating the actuator from the outside. was.

D Problems to be Solved by the Invention However, in the past, an arm attached to an actuator and actuated by the arm was directly connected to a rod attached to a pedal or the like using a pin joint or the like. Therefore, it is necessary to adjust the position of the actuator and pedal, and to adjust the attachment of the rod and arm so that the amount of actuation of the rod sufficiently satisfies the amount of stroke of the pedal, which is a problem in that it takes a lot of effort and time. It was hot. Furthermore, since the arm and rod are connected with a pin,
In the return movement of the rod, the pedal is connected to the actuator as in the depression movement.
The return action of the actuator forces the pedal back. Therefore, there was a problem in that pedals, especially clutch pedals, etc., could not return naturally, making it impossible to reproduce the conditions in actual use.

E. Means for Solving the Problems The present invention solves the above problems, and in order to make installation and adjustment easy and to obtain a natural return movement of the pedal, the actuating device is configured as follows. It is. That is, the actuating end of the actuator is connected to an arm swingably attached to the main body, a rod is attached to the rotating end of the arm so as to be swingable in the axial direction of the rod, and the The pedal operating device is constructed by providing a rotatable grip portion for gripping the pedal, and a stopper that can be locked at any position in the axial direction of the rod and can be engaged with the arm.

F Function The actuator is installed inside the vehicle, and the rod is installed on the pedal of a clutch, etc. An arm attached to an actuator is slidably connected to the rod, and a stopper is fixed to the rod at an appropriate position so that the stroke of the clutch pedal is within the operating range of the actuator. This allows easy setting of the actuating device. When the actuator is actuated, the arm engages the stopper and the pedal is actuated via the rod. When the actuator is pulled back, the arm can slide ahead of the rod if the actuator actuation is faster than the pedal's own return speed, the pedal returns with its own return force, and the actuator forces the pedal back. There is no such thing.

G. Embodiment Hereinafter, an embodiment of the pedal actuating device according to the present invention will be described.

FIG. 1 is a side view of the actuating device 2, showing a state where it is installed inside a vehicle (not shown). The actuating device 2 includes an actuator 4 and a link mechanism 6, the end of which is connected to a clutch pedal 8. The actuator 4 consists of a motor 10, a potentiometer 12, etc. When the motor 10 is operated, an operating shaft 14 reciprocates in the axial direction, and the potentiometer 12 measures the amount of operation. This actuator 4 is fixed at a suitable position in the vehicle by a screw 16, and by removing this screw 16, the actuator can be removed together.

The link mechanism 6 is described below. The link mechanism 6 comprises an arm 18 that swings and a clutch pedal 8.
The arm 18 is made up of two parallel plate-like members as shown in FIG. 2, and is rotatably attached to a support portion 22 that is continuous with the outer frame body of the actuator 4 by a pin 24. The rotating end of the arm 18,
That is, three mounting holes 29 are formed at the upper part of the figure, and the joints 26 are attached to the mounting holes 29. The joints 26 are cylindrical, slidably fitted on the rod 20, and rotatably attached to the arm 18 by a pin 27. Furthermore, a pin 28 is provided on the arm 18 between the joints 26 and the pivot point, and this pin 28 is inserted into an elongated hole 30 in the operating shaft 14 of the actuator 4. The rod 20 is rod-shaped, and a pedal grip 32 is rotatably attached to one end. A stopper 34 is slidably fitted to the outer periphery of the rod 20, and when a set screw 36 on the side of the stopper 34 is screwed in, the stopper 34 comes into contact with the outer periphery of the rod 20 inside the stopper 34, and is fixed to the rod 20. The joints 26 are attached to the rear end of the rod 20.
A ring 38 is attached to prevent the pedal grip portion 32 from coming off. The pedal grip portion 32 is folded back at its upper portion so as to be hooked onto the upper end of the stepping portion 40 of the clutch pedal 8, and a set screw 42 is attached to fix the pedal grip portion 32 in place.

Next, the procedure for attaching the actuating device 2 to the vehicle and its operation will be described. Place the actuator 4 in the vehicle compartment in front of the clutch pedal 8, and tighten the screw 16.
Tighten and secure. A pedal grip part 32 is attached to the clutch pedal 8 and fixed with a set screw 42. Attach the arm 18 to the central mounting hole 29 of the mounting holes 29 with the pin 27, and then attach the rod 2.
0 and arm 18 are connected. Furthermore, arm 18
The joint 26 may be connected in advance before the actuator 4 is fixed. Then, move the stopper 34 along the rod 20, and move the stopper 34 along the rod 20.
Then, fix it to the rod 20 with the screw 36. At this time, if the distance between the joint 26 and the retaining ring 38 is small, the stopper 3
4 toward the pedal 8 side, and fix the stopper 34 by leaving a distance between the next hand 26 and the stopper 34. By doing so, the actuation start position of the clutch pedal 8 can be set. Next, when the actuator 4 is actuated to swing the arm 18, the rod 20 is pushed and the clutch pedal 8 is depressed.
Such a state is shown by a chain double-dashed line in the figure. When the clutch pedal 8 is not fully depressed even when the actuator 4 is operated to the maximum, the pin 27 is removed and the connecting hand 26 is moved to the mounting hole 29 on the rotation end side of the arm 18.

Due to this mounting and operation, installation is very easy since the mounting of the actuator 4 does not require a precise position in relation to the clutch pedal 8. Further, the connection adjustment work of the link mechanism 6 can be easily performed. Further, since the rod 20 and the arm 18 are connected to the rod 20 by a slidable joint 26, the return movement of the actuator 4 is quick and the clutch pedal 8 is fast.
Even if the natural return speed of the clutch pedal 8 were to be exceeded, the arm 18 would slide and lead the rod 20, allowing the clutch pedal 8 to return with its own natural repulsive force.

Although the above example deals with operating the clutch pedal 8, the actuating device of the present invention is not particularly limited to the clutch pedal.

H Effects of the present invention According to the actuating device of the present invention, since a sliding structure is adopted between the arm and the rod, there is no need for strict position adjustment during installation, and it can be installed in the vehicle interior. , adjustment work can be done easily. In addition, since the arm can separate from the rod during the return motion and move independently, even if the actuator's return speed is fast, no unreasonable force is applied to pull back the pedal, allowing the pedal to move naturally with its own natural return force. It can be returned at speed.
