Problems solved by technology

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 natural frequency rubber will often be damaged and cracked

Embodiment Construction

[0025] The following with attached Figure 2 to Figure 4 A torsional vibration damper of the present invention is further described in detail.

[0026] A kind of torsional shock absorber of the present invention, please refer to Figure 2 to Figure 4 , including a mass block 1, a connecting flange 2, and a natural frequency rubber block 3 arranged between the mass block 1 and the connecting flange 2 along the outer periphery of the connecting flange 2, the connecting flange 2 Coaxially arranged in the mass block 1, an axial limit device, a radial limit device and a torsion limit device are arranged between the connecting flange 2 and the mass block 1, and the axial limit The number of the device, the radial limiting device and the twist limiting device is at least one. In this way, during the operation of the vehicle, the axial limit device reduces the axial tearing of the natural frequency rubber block 3 of vibration damping, improves its life, and it also has a limit prote...

Abstract

The invention discloses a torsion damper which comprises a mass block, a connecting flange and inherent frequency rubber blocks arranged between the mass block and the connecting flange and along the outer circumference of the connecting flange. The connecting flange is coaxially arranged in the mass block, 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 number of the axial limiting device, the number of the radial limiting device and the number of the torsion limiting device are all at least one. The torsion damper is simple in structure, the phenomenon that the load of parts exceeds the operation range is limited in the finished vehicle road testing process on the premise that the operation performance of the vehicle parts is satisfied, the torsion fluctuation condition of the transmission shaft is improved, the overall service life of the parts is prolonged, and the maintenance cost of the vehicle is reduced.

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 ...
