Problems solved by technology

[0004] Since the first-order natural frequencies of the drive shafts of different models are not equal, the number of models to be produced requires a corresponding number of shock absorbers. Each type of shock absorber must be molded separately, and the production cost is quite high; in addition, the overall The vibration frequency change caused by the loss of the vehicle will cause the vibration frequency of the transmission shaft vibration absorber to not match the vibration frequency of the transmission shaft, which will affect the NVH (Noise, Vibration, Harshness, noise, vibration and harshness) performance of the vehicle

Abstract

The invention discloses a transmission shaft vibration absorber, and relates to the field of automobiles. The transmission shaft vibration absorber is designed to enable the matching frequency of the vibration absorber to be adjusted conveniently. The transmission shaft vibration absorber comprises an annular rubber block and a quality block arranged outside the annular rubber block, wherein a plurality of through holes are formed in the circumferential direction of the quality block, adjusting bolts are fastened in the through holes, springs are further arranged between the adjusting bolts and the rubber block, one end of each spring is connected with the annular rubber block in a butting mode, and the other end of the corresponding spring is connected with the corresponding adjusting bolt in a butting mode. The transmission shaft vibration absorber can be used in automobile manufacturing.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a transmission shaft vibration absorber. Background technique [0002] When the car is running, the power system always applies various exciting vibrations to the transmission shaft, especially the reciprocating inertial force of the engine and the inertial force impact caused by the imbalance of the transmission shaft. These excitations will cause the transmission shaft to vibrate, and the vibration of the transmission shaft will transmit the excitation energy to the vehicle body through the outer universal joint, wheel hub and suspension. Resonance, producing a low-frequency roar. [0003] In order to avoid the influence of transmission shaft resonance on the performance of the vehicle, a vibration absorber is installed on the shaft of the transmission shaft. The traditional shock absorber is composed of a rubber body and an iron core, wherein the rubber body is a hollow sleeve str...
