Abstract

The invention provides a transmission shaft and an automobile applying the transmission shaft. The transmission shaft comprises a flange and a cross-shaped shaft which are connected in a matching way, wherein the cross-shaped shaft is connected with a shaft fork; the shaft fork is in butt joint with a transmission block in a matching way; a torsion spring is arranged on the outer sides of the shaft fork and the transmission block in a sleeving way; a shaft tube is arranged on the outer side of the torsion spring in a sleeving way through the transmission block; the shaft fork can rotate relative to the transmission block, and is used for driving the torsion spring to be deformed in the shaft tube. By adopting the transmission shaft and the automobile applying the transmission shaft, the problem that the torsion vibration of the transmission shaft cannot be effectively lowered in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a transmission shaft and an automobile using the same. Background technique [0002] The transmission shaft is an important part of power transmission in the automobile transmission system. It can work together with the gearbox and drive axle to transmit the power of the engine to the wheels, so that the car can generate driving force. [0003] Among them, since the drive shaft is a part of the vehicle that transmits torque and rotates at high speed, it is very prone to NVH (Noise, Vibration, Harshness) problems such as vibration, which affects the overall performance of the vehicle . In the prior art, the transmission shaft is mainly composed of a shaft tube, a telescopic sleeve and a universal joint, and the shaft system composed of the shaft tube, the universal joint and the engine is designed by matching to avoid the generation of resonance, thereby reducing the NVH prob...
