Description

[Detailed description of the invention] In the suspension of automobiles, this invention is for stopper rubber and stopper rubber that are attached to each other on the body frame side or the leaf spring side so that the leaf spring and the body frame do not contact each other when bouncing. The present invention relates to a suspension stopper device equipped with a catch seat.

Conventionally, the stopper rubber receiving seat in this type of device is made of metal such as a steel plate with a slippery surface, so when the tip of the stopper rubber comes into contact with the receiving seat, the rolling of the vehicle body causes the stopper rubber tip to slide into the receiving seat. There was a risk that the stopper rubber would slide on the top surface and fall.

For this reason, there is a possibility that the original purpose of the stopper rubber, which is to prevent mutual contact between the leaf spring and the vehicle body frame, cannot be achieved, and therefore, it is necessary to design the width of the stopper rubber to be wider than necessary.

In view of the above, an object of this invention is to provide a stopper device for a suspension in which there is no fear that the stopper rubber will fall down due to rolling of the vehicle body when the tip of the stopper rubber comes into contact with the receiving seat.

The gist of this invention is that in a suspension stopper device that has a stopper rubber on one side of the leaf spring side and the body frame side and a receiving seat on the other side that the tip of the stopper rubber makes contact with, the friction coefficient is A stopper device for a suspension is provided with an elastic member having a large diameter, and at least one of the abutment surfaces of the elastic member and the tip of the stopper rubber is formed into an uneven surface.

An embodiment of this invention will be described below with reference to figures.

Fig. 1 is a partial front view of a suspension with a receiving seat attached according to an embodiment of this invention, and Fig. 2 is a section II-II of Fig. 1.
The line sectional view and FIG. 3 are schematic perspective views showing how this invention is used.

The stopper rubber 1 is bolted to the vehicle body frame 2 or the like.

Further, the stopper rubber 1 is also provided with horizontal through holes 3 and 4 in the vertically intermediate portion thereof so as to obtain the required spring characteristics.

Corresponding to the stopper rubber 1, a catch seat 7 is fixed to a leaf spring 8 with a screw or the like.

This receiving seat 7 has an elastic member 6 made of rubber or the like having a large coefficient of friction attached to the part of the body 5 made of a steel plate or the like that contacts the tip of the stopper rubber 1 by adhesive or other means. .

Both or one of the contact surfaces of the tip of the stopper rubber 1 and the elastic member 6 are formed with an uneven surface.

Next, the operation of the above embodiment will be explained.

When the tip of the stopper rubber 1 comes into contact with the elastic member 6 of the catch seat 7 during bounce, etc., even if the vehicle body rolls,
The receiving seat 7 is provided with an elastic member 6 having a large coefficient of friction, and since at least one of the contact surfaces having a large coefficient of friction is in mutual contact with the elastic material, the tip of the stopper rubber 1 touches the receiving seat. There is almost no slipping on the elastic member 6 of 7.

Therefore, there is no fear that the stopper rubber 1 will fall and the leaf spring and the vehicle frame will come into contact with each other.

Further, in the above embodiment, since the elastic member 6 is provided on the receiving seat 7, the tip of the stopper rubber 1 and the receiving seat 7
It is possible to reduce the spring constant at the initial stage of contact with the vehicle body, and it is possible to reduce the shock when the vehicle body bounces.

The suspension stopper device of this invention has the above-mentioned structure, so when the tip of the stopper rubber comes into contact with the receiving seat, there is no risk of the stopper rubber falling down due to rolling of the vehicle body, and the relationship between the vehicle body frame and the leaf spring is reduced. Contact can be completely prevented, and furthermore, the spring constant at the initial stage of contact between the spring rubber and the receiving seat can be made small, so that the shock when the vehicle body bounces can be alleviated.
