Abstract

The invention discloses an automobile transmission shaft. The automobile transmission shaft comprises a universal joint fork, a transmission shaft pipe, a center shaft and eccentric shafts, wherein one end of the universal joint fork is provided with a first flange, a first center hole is formed in the first flange, and the side wall of the first center hole is provided with a semi-circular ring groove; and the center shaft can move in the axial direction of the transmission shaft pipe, a penetrating hole is formed in the center shaft in the axial direction, a spring and two steel balls are installed in the penetrating hole, the two steel balls are located at the two ends of the penetrating hole, the two ends of the spring abut against the two steel balls correspondingly, and the parts, stretching out of the penetrating hole, of the two steel balls are embedded in the semi-circular ring groove. Due to the fact that the center shaft and the eccentric shafts can move in the transmissionshaft pipe, the requirements for relative position change between a speed changer and the input end of a driving shaft, the eccentric shafts can transmit output power of the speed changer to the inputshaft end of the driving shaft. Reliable torque transmitting is ensured, in addition, by adopting the mode that the center shaft is fixed through cooperation of the steel balls and the spring, the structure complexity is reduced, and the transmission efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile transmission shaft. Background technique [0002] The automobile transmission shaft is an important part connecting the transmission and the drive axle in the automobile transmission system. It is connected between the transmission of the power unit and the input shaft of the drive shaft, and is mainly used to transmit the output power of the transmission to the input shaft of the drive shaft. . According to the impact from the road surface or the operating state of the vehicle, the relative position between the transmission and the input shaft of the drive shaft will change. Therefore, the transmission shaft is required to be able to transmit torque, and the length can be expanded to meet the needs of the transmission and the drive shaft. Relative positional change requirements between input shafts. [0003] In the prior art, the transmission shaft of automob...
