BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure for a vehicle pedal and a clevis in which a vehicle pedal and a clevis are mounted on a collar and then pin-connected with a clevis pin.

[0002]

2. Description of the Related Art In a vehicle pedal, for example, a so-called suspension type brake pedal,
The clevis and the brake pedal provided at the tip of the push rod protruding from the master cylinder are pin-coupled by a clevis pin. This type of structure is disclosed in Japanese Utility Model Laid-Open No. 64-27516, and a conventional connecting structure between a brake pedal and a clevis will be described below using the configuration disclosed in this publication.

FIG. 4 is a perspective view showing the coupling structure of the brake pedal 100 and the clevis 102. In this structure, the brake pedal 100 is formed to have a U-shaped cross section, and the U-shaped clevis 102 attached to the tip end portion of the push rod 104 is inserted into the longitudinal middle portion of one side portion 100A thereof. ing.

More specifically, as shown in FIG. 5, one side portion 100A and the other side portion 100B of the brake pedal 100 are formed with coaxial insertion holes 106 and 108, respectively, and these insertion holes are further inserted. An insertion hole 110 is formed in the clevis 102 coaxially with the holes 106 and 108.
A reinforcing plate 112 is provided on the outer surface of one side portion 100A of the brake pedal 100.
12 also has an insertion hole 114 coaxial with the insertion hole 110 of the clevis 102. Then, these insertion holes 10
The clevis pin 116 is inserted into each of 6, 108, 110 and 114, and the E-ring 118 is fitted to the insertion end portion, so that the brake pedal 100 and the clevis 102 are pin-connected.

Here, the insertion hole 108 formed on the other side portion 100B of the brake pedal 100 has a larger diameter than the insertion hole 106 formed on the one side portion 100A, and the insertion hole 108 is formed. A resin collar (bush) 120 is fitted inside. The collar 120 includes a cylindrical base 120A fitted into the insertion hole 108, a stopper 120B provided at one end of the base 120A and extending in the radial direction, and elastically deformed at the other end of the base 120A. It is composed of a possible claw portion 120C and a holding portion 120D which is integrally extended from the stopper 120B and is bent like a hook.

According to the above construction, when the collar 120 is fitted into the insertion hole 108 of the brake pedal 100, the claw portion 120C elastically deforms, and after the fitting, the claw portion 120C elastically returns to the position between the collar 120 and the stopper 120B. On the brake pedal 10
The other side 100B of 0 is clamped. Furthermore, color 1
When the clevis pin 116 is inserted into the clevis pin 120, the pressing portion 120D is elastically deformed by the head portion 116A of the clevis pin 116, and then the pressing portion 120D elastically returns to contact the head portion 116A to contact the clevis pin 116.
To prevent slipping out.

However, looking at the above-described structure in detail, as shown in FIG. 6, the claw portion 120 of the collar 120 is shown.
The elastic deformation of C causes the insertion hole 108 of the brake pedal 100.
To pass through the claw portion 120C means that the claw portion 120C passes through the insertion hole 108 in the state shown by the chain double-dashed line and then elastically returns (rotates) in the direction of the arrow in the figure to reach the state shown by the solid line. Therefore, in the state in which the collar 120 is assembled, a gap 122 having a gap dimension P is formed between the tip of the claw portion 120C of the collar 120 and the inner side surface of the other side portion 100B of the brake pedal 100. As a result, the collar 120 rattles in the axial direction by the gap dimension P, and the rattle of the collar 120 also rattles the clevis pin 116 in the axial direction.

In consideration of the above facts, the present invention is caused by the backlash of the collar by eliminating the backlash in the axial direction of the collar in the structure in which the vehicle pedal and the clevis are mounted with the collar and then pin-joined with the clevis pin. An object of the present invention is to obtain a connecting structure for a vehicle pedal and a clevis that can prevent the clevis pin from rattling.

According to the present invention, there is provided a vehicle pedal which is swingably supported around a support shaft and has a first insertion hole having a predetermined diameter dimension, and a tip of a push rod protruding from a master cylinder. A clevis that is provided in the portion and that has a second insertion hole of a predetermined diameter dimension, and a tubular collar that is inserted into the first insertion hole and the second insertion hole and that has a through hole in the shaft core portion,
A coupling structure for a vehicle pedal and a clevis, which is inserted into the through hole of the collar and includes a clevis pin for pin-coupling the vehicle pedal and the clevis, wherein one of the axial direction of the collar is By inserting a predetermined amount of the collar into the first insertion hole and the second insertion hole, the end portion is brought into contact with the outer surface of one side portion of the clevis, and a stopper that prevents further insertion of the collar is provided. At the other end of the collar in the axial direction, the collar is elastically deformable around the base point so that the collar can swing, and in the non-swinging state, the outer end portion has a reduced diameter and an inner end portion located near the base point. The diameter of the clevis is expanded and separated from the outer surface of the other side of the clevis.In the rocking state, the outer end of the clevis expands and the inner end of the clevis contracts to contact the outer surface of the other clevis. An oscillating portion that comes into contact with the clevis pin is provided. Maintaining HiYurado state in the previous state to be inserted, the swing state is elastically deformed by the clevis pin is inserted, it is characterized in that.

[0010]

The operation of the present invention will be described below by explaining the assembly procedure.

First, the collar is inserted into the first insertion hole of the vehicle pedal and the second insertion hole of the clevis from the other end side in the axial direction (the side where the swinging portion is provided). The collar is inserted until the stopper comes into contact with the outer surface of the one side of the clevis. At this time, since the clevis pin has not yet been inserted into the through hole provided in the shaft core portion of the collar, the swinging portion of the collar is in the non-swinging state, and the inner end portion of the clevis pin is also on the other side of the clevis. It is separated from the outer surface of the part.

Next, in this state, the clevis pin is inserted into the through hole of the collar from the other end side in the axial direction of the collar. When the clevis pin is inserted, the clevis pin presses the rocking portion of the collar. As a result, the swinging portion of the collar is elastically deformed from the non-swinging state to the swinging state around the base point. In this state, the outer end of the oscillating portion expands in diameter and the inner end contracts in diameter to come into contact with the outer surface of the other side of the clevis.

As a result, when the clevis pin is completely inserted into the through hole of the collar and mounted, the stopper of the collar contacts the outer surface of one side of the clevis, and
The inner end of the swinging portion of the collar contacts the outer surface of the other side of the clevis. Therefore, the collar does not rattle in the axial direction after the collar is assembled. Therefore, the clevis pin does not rattle due to the axial movement of the collar.

When the clevis pin 34 is not inserted into the collar 46, the second elastically deforming portion 54 is in the state shown by the chain double-dashed line in FIG. That is, this state is the second
In the natural state of the elastically deforming portion 54, the outer end portion 54B is located in the diameter reducing direction and the inner end portion 54C is located in the diameter expanding direction. Therefore, in this state, the outer surface of the extending portion 54A is an inclined surface. In this state, the tip of the inner end portion 54C is separated from the outer surface of the other side portion 32B of the clevis 32.

On the other hand, when the clevis pin 34 is inserted in the collar 46, the second elastic deformation portion 54 is in the state shown by the solid line in FIG. That is, this state is a state in which the second elastically deformable portion 54 elastically deforms and swings, the outer end portion 54B is displaced in the radial expansion direction, and the inner end portion 54C is displaced in the radial contraction direction. Therefore, in this state, the extension portion 54

The clevis 32 comes into contact with the outer surface of the other side portion 32B and presses it.

Looking at the above-mentioned four pieces of the second elastically deforming portions 54 as a whole, the shape thereof is substantially the same as the shape of the head 42 of the clevis pin 34, that is, the shape capable of gripping the head 42 of the clevis pin 34. ing.

The operation of this embodiment will be described below through the assembly procedure. First, the insertion hole 38 of the one side portion 32A of the clevis 32 and the insertion hole 3 of the brake pedal 10

The entire deforming portion 54 does not swing, but only the outer end portion 54B is pushed and expanded in the radial direction. This allows the clevis pin 3
The four heads 42 are mounted inside the second elastically deforming portion 54 while being gripped.

In this state, that is, in the state in which the second elastically deforming portion 54 is returned to the state shown by the solid line, as described above, the stopper 50 abuts on the outer side surface of the one side portion 32A of the clevis 32, and the collar Since the inner end portion 54C of the second elastically deformable portion 54 of 46 abuts on the outer surface of the other side portion 32B of the clevis 32, the collar 46 does not move in the axial direction with respect to the clevis 32. Also, in this state,
Since the head 42 of the clevis pin 34 is held in a form gripped by the second elastic deformation portion 54, and the elastic restoring force of the second elastic deformation portion 54 acts on the head 42. The clevis pin 34 does not move in the axial direction with respect to the collar 46.

As described above, in this embodiment, the clevis pin 3 is used.

It is possible to prevent rattling of the No. 6 clevis 32. Therefore, it is possible to prevent the clevis pin 34 from moving in the axial direction (causing the rattling) due to the axial movement (rattle) of the collar 46.

Not only according to this embodiment, the color 4
Since the head 42 of the clevis pin 34 is held by the second elastically deforming portion 54 of No. 6 and the elastic restoring force of the second elastically deforming portion 54 acts on the head 42. It is also possible to prevent the clevis pin 34 from moving in the axial direction with respect to the collar 46, and thereby to prevent the clevis pin 34 from rattling with respect to the collar 46.

In general, the former effect (even if the clevis pin 34 itself does not rattle against the collar 46)
Clevis pin 34 dragged by rattling of collar 46
It is possible to prevent the clevis pin 34 from rattling against the collar 46 (even if the collar 46 itself does not rattle against the clevis 32). By virtue of both of them, the rattle of the clevis pin 34 with respect to the clevis 32 can be completely eliminated.

Further, conventionally, a hole is provided at the tip of the clevis pin 34, and a beta pin is inserted into this hole so as to prevent the clevis pin 34 from coming off. According to the present embodiment, the clevis pin 34 is formed by the second elastic deformation portion 54.
Since it is prevented from coming off, the above-mentioned work becomes unnecessary and the workability can be improved.

In this embodiment, the brake pedal 10
Although the present invention is applied to the above, the present invention is not limited to this, and the present invention may be applied to a clutch pedal.

Further, in this embodiment, the shaft portion 40 and the head portion 4
2, the clevis pin 34 in which the locking portion 44 is integrally formed is used, but the present invention is not limited to this. It is also possible to adopt a configuration such as forming a male screw, and in this case as well, the effects described above can be obtained.

Further, in this embodiment, the collar 46 is the second
In addition to the elastically deforming portion 54, the first elastically deforming portion 52 is provided,
Although the first elastically deformable portion 52 is elastically deformed at the time of insertion, the first elastically deformable portion 52 is not necessarily an essential element, and may be configured as follows, for example. For example, the collar 46 is divided into two parts at the axially intermediate portion of the shaft portion 48, and the portion including the stopper 50 and the portion including the second elastic deformation portion 54 are inserted into the clevis 32 from mutually opposite sides. Then, both can be integrated by engaging with each other by the inserting operation. Engagement can be achieved by providing a claw that is elastically deformable in the circumferential direction at the end of one part and providing a claw or a protrusion that engages with this claw at the end of the other part, or the end of one part. L-shaped leaf springs are attached to the sides at regular intervals in the circumferential direction.

In a swinging state in which the clevis pin is inserted, the outer end portion has a larger diameter and the inner end portion has a smaller diameter, and the second elastic deformation portion comes into contact with the outer surface of the other side portion of the clevis. And further, the head of the clevis pin is gripped by the second elastically deforming portion being in a swinging state. " In addition to the effects, the following actions and effects can be obtained.

That is, when the clevis pin is inserted into the collar, the second elastically deformable portion oscillates about the base point, and the second elastically deformable portion is in an oscillating state so that the head of the clevis pin is gripped. Therefore, in this state, the clevis pin cannot move axially with respect to the collar. Therefore, not only does the clevis pin play due to the axial play of the collar, but also the clevis pin play due to the relative movement of the clevis pin with respect to the collar does not occur.

A clevis having a second insertion hole, a cylindrical collar inserted into the first insertion hole and the second insertion hole, and having a through hole in the shaft core, and inserted into the through hole of this collar. And a clevis pin for pin-connecting the vehicle pedal and the clevis, and a connecting structure for the vehicle pedal and the clevis, which comprises: By inserting a predetermined amount of the collar into the hole and the second insertion hole, the collar is brought into contact with the outer surface of one side portion of the clevis, and a stopper is provided to prevent further insertion of the collar. Elastic deformation around the base point on the other end The outer end is reduced in diameter and the inner end located near the base point is expanded in the non-oscillated state and is separated from the outer surface of the other side of the clevis. In the rocking state, the outer end part has a larger diameter and the inner end part has a smaller diameter, and a rocking part is provided which comes into contact with the outer surface of the other side of the clevis. In the state before it is kept in a non-swinging state, when the clevis pin is inserted, it is elastically deformed into a swinging state, which is a coupling structure between a vehicle pedal and a clevis.
