Vehicle hanging system

Abstract

The invention discloses a vehicle hanging system. The vehicle hanging system comprises a damper and a rocker arm and further comprises a bracket and a pull rod, the bracket comprises a bracket fixingpoint, a damping mounting pint, and a pull rod mounting point, one end of the damper is rotatably connected with the damping mounting point, one end of the pull rod is rotatably connected with the pull rod mounting point, and the other end of the pull rod is connected with the rocker arm; and the first distance from the damping mounting point to the bracket fixing point is less than the second distance from the pull rod mounting point to the bracket fixing point. According to the vehicle hanging system, through the connection relationship between the rocker arm, the bracket, the pull rod and the damper, meanwhile, through the distance relationship of the three mounting points on the bracket, the larger displacement on the pull rod is converted into the smaller displacement on the damper accordingly, so that the stroke of the rocker arm is effectively increased under the premise without increasing the damping stroke so as to adapt the driving road condition of all terrains and vehicles,meanwhile, the deformation of the rocker arm or a vehicle frame due to the dead jacking of the upward jumping of the rocker arm as the damping stroke is small is avoided, and in addition, as the pullrod is forced by the pulling force, the force limit can be effectively improved.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a vehicle suspension system. Background technique [0002] The driving conditions of the all-terrain vehicle are usually rough, and the wheels bounce greatly when the vehicle is running. Existing all-terrain vehicles mostly use a shock absorber device with a coil spring and a damper. Due to the large wheel runout, the required stroke of the shock absorber increases, and the size and quality of the shock absorber will increase accordingly, which is not conducive to the overall vehicle. lightweight design; in order to meet the driving requirements, the performance of the shock absorber needs to be improved accordingly, and the cost of the vehicle will also increase accordingly; If the wheel jumps beyond the highest point, it will easily cause the deformation of the rocker arm.

Problems solved by technology

Existing all-terrain vehicles mostly use a shock absorber device with a coil spring and a damper. Due to the large wheel runout, the required stroke of the shock absorber increases, and the size and quality of the shock absorber will increase accordingly, which is not conducive to the overall vehicle. lightweight design; in order to meet the driving requirements, the performance of the shock absorber needs to be improved accordingly, and the cost of the vehicle will also increase accordingly; If the wheel jumps beyond the highest point, it is easy to cause the deformation of the rocker arm

At the same time, the shock absorber is directly installed on the rocker arm. Due to the large radial dimension of the shock absorber, it is easy to cause the installation space to be too compact and increase the difficulty of assembly.
