Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention mainly relates to a steering force measuring device used for steering force inspection on a steering inspection stage of a completed vehicle.

(Prior Art) Conventionally, as this type of device, according to Japanese Utility Model Laid-Open No. 60-134132, as shown in FIG. 4, an engagement sleeve fitted to a nut c on the top of a steering shaft b connecting a steering wheel a. A mounting arm e having d fixed thereto, an elastically deformable handle arm g having one end fixed to the mounting arm e and a handle f attached to the other end, and a pointer h for detecting an elastic deformation amount of the handle arm g. It is known that the steering force is measured by including the scale plate i and the elastic deformation amount of the handle arm g when the handle f is steered.

(Problems to be solved by the invention) In the above-mentioned one, the members such as the horn switch cover attached to the central portion of the steering wheel a are removed one by one,
It is necessary to fit the engagement sleeves d to the nuts c, and it takes too much time to inspect all the completed vehicles, and the measuring device becomes large due to the presence of the arms e and g and the scale plate i, and the steering wheel a is When the steering device is operated to perform other steering inspections such as a corner angle inspection, it is necessary to remove the measuring device so as not to disturb the measuring device, and a series of steering inspections at the inspection stage cannot be continuously and efficiently performed.

An object of the present invention is to provide a small measuring device capable of measuring the steering force without changing the steering wheel in order to solve such a problem.

(Means for Solving the Problems) In order to achieve the above object, the present invention includes a base frame that can be fixed to a part of a grip ring of a steering wheel, and an outer surface of the base frame in a tangential direction of the grip ring. An extending seat is provided, and a slider having a handle attached to the outer surface of the seat is slidably supported in the tangential direction, and pressure is applied to the tangential direction opposing portion of the seat and the slider. It is characterized in that a sensor is provided.

(Operation) The base frame is fixed to the grip ring of the steering wheel, and the handle of the slider is gripped to rotate the wheel.

According to this, the slider slides in the tangential direction of the grip ring by the steering force, and the pressing force according to the steering force acts on the pressure-sensitive sensor provided in the tangential direction opposing portion of the slider and the seat. Then, the steering force is detected by the sensor.

Further, the measuring device of the present invention is attached to a part of the grip ring, and the steering wheel can be operated by holding the other part of the grip ring. It can be obtained continuously without removing.

(Embodiment) Referring to FIGS. 1 to 3, (1) is a grip ring of a steering wheel, and (2) is a groove (3) which can be fitted in a part of the grip ring (1). Shows the base frame that was made, in the base frame (2),
In a pair of guide bolts (4a) (4a) in which a clamp piece (4) which is located on one side of the concave groove (3) and is opposed to the grip ring (1) and which is long in the circumferential direction is planted Tightening bolts (5) that slidably support and contact the back surface of the clamp piece (4).
And the clamp bolt (5) pushes the clamp piece (4) to the other side of the recessed groove (3), that is, the closed side, so that the base frame
(2) can be clamped and fixed to the grip ring (1).

In the drawing, (6) is the friction material attached to the inner surface of the groove (3) and the front surface of the clamp piece (4), and (4b) is the clamp piece (4) attached to the outer end of each guide bolt (4a). The return spring urged to the opening side is shown.

In addition, the seat (7) extending in the tangential direction of the grip ring (1) is bolted (8) to the outer surface of the base frame (2), and the seat (7) has a concave groove for receiving this. The slider (9) is slidably supported in the tangential direction via the cross roller bearings (10) (10) on both sides of the inner surface of the groove, and the bolt (1
1) Attach the handle (12) to the fixed mounting plate (9a) with the mounting bolts (12a) that pivotally support the handle (12), and further attach the handle (12) to both ends of the slider (9) at opposite ends of the seat (7) Plates (9b) (9b) with screws (1
3) Stop and form an opposing portion that tangentially faces each of the end plates (9b) and the end surface of the seat (7).
Each pressure-sensitive sensor consisting of a load cell assembled in (9b)
A cord (14a) provided with (14) and connected to each pressure-sensitive sensor (14)
Is connected to an appropriate indicator (not shown) through the collective cable (14b) attached to the base frame (2).

Next, a method of using the above embodiment will be described.

After the finished vehicle is loaded onto the steering inspection stage, first place the base frame in the proper position on the grip ring (1) of the steering wheel.
(2) is fitted in the groove (3) and the tightening bolt (4b) is tightened, the base frame (2) is fixed to the grip ring (1), and then the handle (12) is gripped. Rotate the steering wheel.

According to this, the slider (9) slides in the tangential direction of the grip ring (1), and the pressure-sensitive sensor (1
4) comes into contact with the end surface of the seat (7) opposed to this, and a pressing force according to the steering force acts on the sensor (14), and the sensor (14)
The steering force is displayed on the display by the output signal from the.

After inspecting the steering force as described above, the steering wheel is operated with the base frame (2) attached, and a series of other steering inspections such as a corner angle inspection are continuously performed.
After the inspection is completed, the base frame (2) is removed from the grip ring (1) and the completed vehicle is transported to the next inspection stage. Although the pressure sensor (14) is attached to the end plate (9b) of the slider (9) in the above embodiment, it may be attached to the end face of the seat (7).

(Effects of the Invention) As described above, according to the present invention, the steering force can be measured by a small measuring device attached to a part of the steering wheel. It is not necessary to remove a member such as a switch cover, the steering wheel can be operated even with the measuring device attached, and a series of steering inspections can be continuously and efficiently performed, which has the effect of improving work efficiency.
