Abstract

The invention discloses a frequency-adjustable vibration damping ring and a drive shaft assembly. The frequency-adjustable vibration damping ring includes: a vibration damping ring body, at least one notch is arranged on the vibration damping ring body; Both detachable connections have at least one spacer. The invention provides a frequency-adjustable vibration damping ring and transmission shaft assembly, which can precisely control and change the frequency of the vibration damping ring, reduce the time taken for disassembly and assembly in the evaluation process, and solve the problem that the evaluation result is affected by different installation positions.

Description

technical field [0001] The invention relates to the technical field of transmission shaft accessories, and more specifically, to a frequency-adjustable vibration damping ring and a transmission shaft assembly. Background technique [0002] After installing the vibration damping ring on the transmission shaft of the car, it can block the transmission path of abnormal vibration. The vibration damping ring can significantly improve the NVH (noise, vibration, abnormal sound) performance of the transmission shaft of the car, and improve the comfort of the car ride. It is a solution Effective means for vehicle NVH problems. [0003] Due to the single structure of the existing vibration damping ring, after the shape and material are fixed, the frequency it has is also relatively fixed. In the NVH debugging process, it takes a lot of time and cost to install vibration damping rings with different frequencies on the drive shaft and conduct vehicle debugging in order to find the vibr...
