Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings of the embodiments.

[0024] Such as figure 1 , figure 2 with image 3 As shown, a shock-absorbing and buffering device for a leaf spring suspension includes a frame 22 and a leaf spring 23. One end of the leaf spring 23 is connected to the frame 22. The frame 22 is provided with a shock-absorbing and buffering device. An elastic cantilever beam 14 is provided below, and the front end of the elastic cantilever beam 14 and the leaf spring 23 are in a corresponding suspension relationship.

[0025] The front end of the elastic cantilever beam 14 and the leaf spring 23 are correspondingly suspended with a rubber buffer block 15.

[0026] The damping and buffering device includes a spiral spring upper bracket 4 and a spiral spring lower bracket 1. The spiral spring upper bracket 4 and the spiral spring lower bracket 1 form a frame structure, and the side of the frame stru...

Abstract

The invention relates to a shock absorbing and buffering device for a leaf spring suspension, comprising a frame and a leaf spring, one end of the leaf spring is connected to the frame, a shock absorbing and buffering device is arranged on the frame, and an elastic cantilever is arranged under the shock absorbing and buffering device The beam, the front end of the elastic cantilever beam and the leaf spring form a corresponding suspension relationship; the front end of the elastic cantilever beam and the leaf spring form a corresponding suspension with a rubber buffer block; when the leaf spring is excessively deformed or subjected to upward impact, the leaf spring will first The rubber buffer blocks on the elastic cantilever beam are in contact; when the leaf spring continues to move upward, the elastic cantilever beam is squeezed by the leaf spring, deforms, and transmits the force to the coil spring; the coil spring is deformed by force and absorbs the kinetic energy of the leaf spring , converted into its own potential energy, so as to ease the impact of the leaf spring, play the effect of shock absorption and buffering and protect the rubber stopper.

Description

Technical field [0001] The invention relates to the field of automobile suspension, and belongs to a shock-absorbing buffer device of a leaf spring suspension. Background technique [0002] When the vehicle is overloaded or impacted by the road, the leaf spring suspension will be excessively deformed or jumped. Therefore, vehicles using leaf spring suspensions are generally equipped with rubber limit blocks to prevent the leaf spring suspension from colliding with the frame, protect the leaf springs, and improve the service life of the leaf springs, such as patents CN203793060U and CN105059074A A rubber limit block device in a suspension is disclosed. However, in practical applications, the rubber limit block often falls off after a period of use, causing the limit device to lose its function. Therefore, if a shock-absorbing buffer device is used to relieve the impact of the leaf spring suspension before the leaf spring suspension collides with the limit block, the use time of ...
