Embodiment Construction

[0034] The biggest difference from the prior art is that this specific embodiment mainly uses a liquid substance with a certain viscosity, such as lubricating oil with a certain viscosity, to absorb vibration and noise with different damping at different vibration frequencies. After a large number of tests, it has been shown that this kind of noise reduction and vibration reduction method can better absorb the vibration and noise transmitted by the vehicle drive shaft in a wide frequency range due to the application of the damping characteristics of lubricating oil during vibration to absorb vibration and noise. , which can greatly improve the ride comfort of the car.

[0035] The shock absorber of the entire vehicle drive shaft is in the form of a ring. figure 1 shown, press-fit on the drive shaft tube 2. The vehicle transmission shaft shock absorber of this specific embodiment is as follows: figure 2 As shown, an inner member 51 is included, as well as a damper housing 52...

Abstract

The invention discloses a method for reducing the vibration of a vehicle driving shaft, which comprises the following steps: measuring the main vibration frequency of the vehicle driving shaft; designing the size of each part of a shock absorber of the vehicle driving shaft; manufacturing a shock absorber shell, a shock absorber cover and middleware; installing the middleware in the shock absorber shell; filling the gap between the middleware and the shock absorber shell with lubricating oil; buckling the shock absorber cover on the shock absorber shell; and finally assembling the components on the vehicle driving shaft together. The invention also discloses the shock absorber for the vehicle driving shaft, which comprises the middleware, the shock absorber shell and the shock absorber cover, wherein the shock absorber shell is buckled with the shock absorber cover to form an annular enclosed space to receive the middleware; and the lubricating oil is filled between the middleware and the shock absorber shell. With the technical proposal of the invention, the method for reducing the vibration of the vehicle driving shaft and the shock absorber for the vehicle driving shaft can better absorb vibrations and noises transmitted by the vehicle driving shaft in a wider frequency range due to the application of the damping characteristic of the lubricating oil in vibrating to absorb the vibrations and the noises, thereby greatly improving the riding comfort of the vehicle.

Description

technical field [0001] The invention relates to the technical field of vehicle vibration reduction, in particular to a vehicle transmission shaft vibration reduction method and a vehicle transmission shaft vibration damper. Background technique [0002] The vehicle drive shaft is used to transmit the rotational power generated by the engine to the input shaft of the axle device to rotationally drive the wheels of the vehicle. Today's vehicle driveshafts are generally such as figure 1 As shown, it mainly includes a sliding fork 1 and a drive shaft tube 2 . One end of the drive shaft tube 2 is welded with a welding fork 3 . The welding fork 3 dynamically connects the drive shaft tube 2 and the sliding fork 1 through the universal joint 4, and allows a certain amount of angular deviation between the axis of the drive shaft tube 2 and the axis of the sliding fork 1. A problem often encountered with vehicle driveshafts is that they tend to transmit and amplify unexpected noise...
