A driven disk assembly of torsional shock absorber without coil spring based on torsional vibration damping belt

Abstract

The invention discloses a spiral-spring-free torsion damper driven disc assembly based on torsion damping belts. The multiple torsion damping belts are adopted to replace original spiral springs to serve as torsion damping elements, abnormal abrasion of the damping elements and clamping components of the damping elements is avoided, the torsion damping curve is perfectly matched with the pressingforce curve of a pressing disc, and the torsion damping performance is more comfortable, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of a shock absorber driven disk assembly, in particular to a torsional shock absorber driven disk assembly without a coil spring based on a torsional vibration damping belt. Background technique [0002] At present, the torsional vibration damping clutches of traditional automobiles all use coil springs for torque transmission and vibration damping, and the coil spring transmission torque vibration damping driven discs have become the mainstream products in the clutch market and are growing rapidly. [0003] After analyzing the force mode and fracture form of the coil spring in the existing torsional shock absorber structure, it is found that the coil spring is subjected to the centrifugal force in the direction of the outer diameter during high-speed rotation, which will cause the spring to appear outward. Waist-drum shape, at this time, the window holding the spring is seriously deviated from the geometric...

Problems solved by technology

Angular movement of the spring and eccentric loading during movement Severe wear and tear Spring installation window of the clamp

Secondly, the current status of spring steel wire material composition and heat treatment process cannot meet the requirements of clutch torsional vibration damping, so the life of the shock absorber is greatly limited

[0004] Although the torsion angle of the damping spring and the linear characteristics of the torque load can meet the needs of torsional vibration damping, the coil spring uses a spring steel wire wound damping element, and its fatigue life is generally difficult to reach 5 million times (strengthened test 100 million times) national standard

The clutch driven disc assembly often breaks the vibration damping spring within the specified service life, and the spring loosens due to the wear of the clamping parts, causing the clutch to be scrapped

[0005] Moreover, for long-distance transport vehicles, the reliability and comfort requirements for torsional vibration reduction are relatively high, and the existing clutches do not specifically consider the comfort requirements of automobiles. Commonly known as "secondary or third-stage vibration reduction" driven plate assembly
