Description

Spring automatic assembly device of clutch driven disc

Technical Field

The utility model relates to the technical field of automobile part assembly, in particular to an automatic spring assembly device of a clutch driven disc.

Background

The clutch ensures the transmission of engine power, and has good engagement smoothness and complete separation. However, resonance phenomenon is caused by the fact that the natural vibration frequency of the driving performance and the working frequency of the engine are mutually heavy, so that all parts of the automobile are damaged early. In order to avoid resonance and to alleviate the impact load to which the drive train is subjected, torsion dampers are fitted into some automobile clutch driven discs.

The torsional vibration damper is characterized in that 4-8 rectangular window holes are formed in a driven disc, an outer disc hub and a vibration damping disc, vibration damping springs are arranged in each window hole, the driven disc, the outer disc hub and the vibration damping disc are riveted into a whole by rivets or limiting pins, gaps matched with rivet spacers are formed in the outer disc hub, and a certain gap is reserved between the gaps and the spacers. Allowing a corresponding angle between the driven disc and the outer hub.

When the engine works, torque must pass through a plurality of vibration reduction springs arranged along circumferential tangents, after the vibration reduction springs are compressed to a certain stroke, the limiting pins collide with the notches of the vibration reduction hubs, and the maximum deformation of the vibration reduction springs is limited. Friction damping sheets are riveted on two sides of the movable disc and float between the driven disc and the vibration damping disc. Due to the action of the springs and the friction damping sheets, the amplitude of torsional vibration is effectively reduced, and the torsional amplitude is attenuated.

In connection with the assembly shown in fig. 1, the spring needs to be assembled into the window of the driven disc, but the rigidity of the spring is high, the manual assembly can take a long time, and the semi-automatic assembly using a tool can still occur due to unsafe factors of jumping out of the assembly of the spring, so that an automatic assembly device for the spring of the driven disc is needed.
