Abstract

The invention discloses a circular-arc spring shock absorber. The circular-arc spring shock absorber comprises a drive disc as well as a flange and a cover plate which are fixedly arranged on the drive disc, wherein a slide slot is formed between the drive disc and the cover plate; an arc-shaped spring is arranged in the slide slot; and the two ends of the arc-shaped spring are connected with the flange. According to the circular-arc spring shock absorber disclosed by the invention, the arc-shaped spring is arranged in the slide slot between the drive plate and the cover plate, power of the drive disc is transmitted to the arc-shaped spring, power is transmitted to the flange through the arc-shaped spring, and the flange is used for transmitting power to a driven disc; when the arc-shaped spring is compressed to twist in the slide slot, a twisting angle which is twice that of a common shock absorber can be obtained, and torque is as large as that of the common shock absorber, so that twisting rigidity which is only one half that of the common shock absorber is obtained. The invention provides the shock absorber capable of simultaneously meeting requirements of low rigidity and large torque, so that a car transmission system has large torque and low rigidity, and therefore, the NVH problem of the car transmission system is solved.

Description

technical field [0001] The invention relates to the field of automobile transmission system, in particular to a shock absorber. Background technique [0002] The shock absorber of the automobile transmission system has two important functions in the use of the automobile transmission system: good vibration reduction effect and sufficient torque transmission capacity. The transmission system achieves the effect of reducing the vibration and noise of the car engine through the torsional shock absorber, and the torsional shock absorber transmits the torque of the engine to the gearbox at the same time. In practical applications, lower stiffness has better vibration damping effect, and to obtain lower stiffness, a larger torsion angle must be designed; The coil spring is limited by the design structure of the shock absorber, and the torsion angle cannot be larger, so the stiffness cannot be smaller. Contents of the invention [0003] In order to overcome the deficiencies of ...
