Plug-in type automobile transmission shaft

The utility model belongs to the technical field of transmission shafts, and particularly relates to a plug-in type automobile transmission shaft which comprises a transmission shaft tube, and a pair of universal joint forks is installed at the end of the transmission shaft tube. The universal joint forks are symmetrically arranged on the two sides of the transmission shaft pipe. A cross bearing is arranged on the inner wall of the universal joint fork; in the using process, the universal joint fork and the cross bearing collide with each other in the operation process, at the moment, the cross bearing makes contact with the surface wall of the annular baffle firstly in the process of colliding with the universal joint fork, a first spring is squeezed to make contraction motion, and therefore the collision force of the cross bearing to the universal joint fork is relieved; therefore, the situation that in the using process of the universal joint fork and the cross-shaped bearing, the cross-shaped bearing cann
