Detailed Description

For a better understanding of the present invention, reference is made to the following description taken in conjunction with the accompanying drawings and examples.

As shown in figures 1-2, the bracket for the air suspension of the mid-damper is in a Z-shaped plate strip shape, one end of the bracket is provided with a hinge pin hole 6, the other end of the bracket is bent downwards and then provided with an air bag bottom support 3, one side of the middle part of the bracket, which corresponds to the hinge pin hole, is provided with a middle hole cavity 1, the lower end of the middle hole cavity is provided with a hinge hole seat 2, and the other side of the middle part of the bracket, which is close to the bending part, is provided.

The middle hole cavity is long and narrow, is symmetrically arranged on the longitudinal center line of the bracket and is communicated up and down, and the two sides of the lower end of the middle hole cavity are provided with hinge hole seats adjacent to the side of the connecting seat. The middle hole cavity is arranged along the longitudinal center of the whole bracket, and the shock absorber is installed relative to the longitudinal center, so that the road vibration can be effectively absorbed, the vibration braking smoothness of the vehicle is improved, the torque on the bracket is reduced, and the structure of the whole suspension is stable. And hinged hole seats are arranged on two sides of the lower end of the middle hole cavity, which are adjacent to the connecting seat.

The lower end face of the connecting seat is of an inwards concave U-shaped structure and is configured with the outline of the top of the wheel shaft, bolt holes 7 are formed in four corners of the connecting seat, and the connecting seat is tightly connected with the wheel shaft through connection of the two U-shaped bolts.

Gasbag collet both sides evagination is fan-shaped, also can be racket shape or palm shape, has increased the holding area of gasbag collet for air bag's erection joint is more firm, prolongs air bag's life, avoids the atress inequality to lead to air bag to take place to break. The center of the air bag bottom support is provided with an air bag mounting hole 5 for connecting an air bag.

The bracket is a whole forging piece, and the hinge pin hole at one end of the bracket and the hinge hole seats at the bottoms of the two sides of the lower end of the middle neutral position are integrated with the bracket, so that the structure is stable, and the bearing capacity is high.
