a torsional shock absorber

Abstract

The invention discloses a torsional vibration absorber, which comprises a mass block, a connecting flange, and a natural frequency rubber block arranged between the mass block and the connecting flange along the outer periphery of the connecting flange. The connecting flange is coaxially arranged in the mass block, and an axial limiting device, a radial limiting device and a torsion limiting device are arranged between the connecting flange and the mass block, and the axial limiting device The number of the device, the radial limiting device and the twist limiting device is at least one. The torsional shock absorber of the present invention is simple in structure, and on the premise of satisfying the working performance of automobile parts, it is limited to the occurrence of loads beyond the working range of the parts during the road test of the whole vehicle, improves the torsional fluctuation of the transmission shaft, and improves the overall use of the parts Long life, reduce car maintenance cost.

Description

technical field [0001] The invention relates to a shock absorber, in particular to a torsional shock absorber for a vehicle body. Background technique [0002] The shock absorber structure sold and used in the existing market is as shown in the accompanying drawing figure 1 As shown, a natural frequency rubber block is filled between the mass block and the connecting flange to reduce the vibration caused by the vibration of the engine. However, in actual application and testing, the vibration of the transmission shaft is relatively serious, which is mainly caused by the vibration of the engine, the fluctuation of the output torque, and the arrangement and structure of the transmission shaft; during the road test of the whole vehicle, four natural frequencies appear Rubber, which mainly plays the role of absorbing torsional vibration, but in the actual operation process, due to the harsh working conditions of the natural frequency rubber, it will tear and fail early, so the ...
