Suspension system and pallet truck with suspension system

Abstract

The invention discloses a suspension system. The suspension system comprises a driving system and an auxiliary wheel assembly arranged on the side face of the driving system, wherein a driving bracketis arranged between the driving system and a vehicle body, a hinge is arranged between one end of the driving bracket and the vehicle body, a buffer element is arranged between the other end of the driving bracket and the vehicle body and used for alleviating vertical vibration of the driving bracket, and an elastic element is arranged between the auxiliary wheel assembly and the vehicle body. According to the suspension system, the auxiliary wheel assembly is elastically connected with the vehicle body, and the elastic element is semi-rigid and has the characteristic of rigidity after beingcompressed, so that the driving system is semi-rigid; the buffer element has certain compression amount when being impacted, so that the driving system also has elasticity and a buffering and dampingeffect and can be effectively protected from the influences of impact and vibration, and the service life of the driving system is effectively prolonged. The invention also discloses a pallet truck comprising the suspension system.

Description

technical field [0001] The invention relates to the technical field of shock absorption, and more specifically, to a suspension system. In addition, the present invention also relates to a pallet truck comprising the above-mentioned suspension system. Background technique [0002] The existing pallet truck suspension system generally adopts a rigid connection between the drive system and the vehicle body, and the auxiliary wheels installed on both sides of the drive system are elastically connected to the vehicle body. Although this system can prevent the driving wheels from slipping, due to the The body is rigidly connected, and there is no buffer and shock absorption function. The components of the drive system are easily damaged by vibration, which affects the service life. [0003] To sum up, how to prolong the service life of the drive system is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] In view of this, the object...
