Problems solved by technology

[0007] Recently, external torsional dampers have been applied in batches on some models due to their simple structure and moderate cost. The dynamic balance of the vibrator and the transmission shaft assembly adds a lot of extra cost; in addition, the external torsional vibration Affect the life of the torsional vibration damper
[0008] The built-in torsional damper can solve the above problems well; but at present, the built-in type is mainly used to deal with high-frequency resonance problems; if the built-in type is used to deal with low-frequency problems, the durability of elastic components (built-in type is mainly rubber) sex is a serious test

Embodiment Construction

[0033] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0034] In the present invention, unless stated otherwise, the orientation words used such as "axial, radial and circumferential" are usually relative to the axial, radial and circumferential directions of the torsional shock absorber, "Inside and outside" refer to the inside and outside of the outline of the corresponding part.

[0035] Such as Figure 1 to Figure 5 As shown, the present invention provides a torsional shock absorber, which can be installed on the transmission shaft of the transmission system, specifically, the torsional shock absorber includes a tubular skeleton 10 for being installed inside the shaft tube, and is set The damping shaft core 20...

Abstract

The invention discloses a torsion shock absorber, a transmission shaft and a vehicle. The torsion shock absorber comprises a tubular skeleton and a damping shaft core arranged in the tubular skeletonand further comprises a plurality of elastic parts connected between the tubular skeleton and the damping shaft core. The elastic parts are arranged along the outer surface of the damping shaft core at intervals. The elastic part axial projections located at the end of the torsion shock absorber are distributed and arranged in the circumferential direction at intervals. In this way, normal twisting of the damping shaft core relative to the tubular skeleton can be ensured, friction between the elastic parts and the tubular skeleton and the damping shaft core is reduced, and heat effect on the elastic parts is weakened; and in addition, gaps between the elastic parts provide deformation spaces of the elastic parts, the fact that the elastic parts are forced to be plastic-deformed or damageddue to no deforming spaces is prevented, the durability of the elastic parts is improved, and the service life of the torsion shock absorber is prolonged.

Description

technical field [0001] The invention relates to the field of shock absorption and noise reduction, in particular to a torsional shock absorber, a transmission shaft including the torsional shock absorber and a vehicle including the torsional shock absorber. Background technique [0002] The torque transmitted from the engine to the transmission system of the vehicle changes periodically, so that the transmission system produces torsional vibration. In a certain speed range of the engine, the vibration frequency may be close to or coincide with the natural frequency of the transmission system. Resonance not only has a great impact on the life of parts in the transmission system, but also some vibrations will be transmitted to the body, resulting in the vibration of the whole vehicle, or transmitted to the driver and passengers in the cabin in the form of low-frequency noise, seriously affecting the driving experience . In addition, with the increasing popularity of passenger...
