Vehicle and torsion damper thereof

Abstract

The invention discloses a torsion damper which comprises a driving side and a driven side. The driving side and the driven side are elastically connected through an elastic piece, and the pre-tightening stroke of the elastic piece is adjustable. By means of the torsion damper, the pre-tightening stroke of the elastic piece is changed, and the torsional rigidity of the torsion damper is changed. As the torsional rigidity is directly related to the frequency of the torsion damper, the frequency of the torsion damper is further changed. When the torsion damper is applied to different vehicle types and the frequency of the torsion damper needs to be adjusted, a new product does not need to be developed, only the pre-tightening stroke of the elastic piece needs to be adjusted, and therefore the frequency of the torsion damper meets the new requirement. Furthermore, the universality of the torsion damper is good, the development cost of the product is better reduced, quick adjustment can be achieved, and the production cost is saved. The invention further discloses a vehicle comprising the above torsion damper.

Description

technical field [0001] The present invention relates to the technical field of vehicles, more specifically, to a torsional shock absorber, and also to a vehicle comprising the aforementioned torsional shock absorber. Background technique [0002] Cars are a very common means of transportation for people's daily travel. At present, automobiles are prone to transmission system excitation resonance, or vibration of the transmission system caused by factors such as the fluctuation of the output torque of the transmission shaft and the layout of the transmission shaft. To solve this problem, a torsional shock absorber is usually added to the transmission system to counteract the torsional vibration of the transmission system. [0003] see figure 1 , figure 1 It is a structural schematic diagram of a common torsional vibration damper in the prior art. The torsional vibration damper in the prior art mainly includes a mass ring 01 , a connecting rubber 02 and a mounting ring 03 ...
