Abstract
The utility model provides an automobile transmission shaft assembly. A transmission shaft pipe weldment in the automobile transmission shaft assembly is provided with a collapse spline safety device. The collapse spline safety device comprises a spline shaft fork, a spline sleeve, an obturating ring and a safety connector, and the spline shaft fork and the spline sleeve compose a spline pair. The safety connector can be a safety pin or a non-metal safety retainer ring or a metal safety retainer ring. The spline shaft fork and the spline sleeve are connected into a spline pair entirety through the safety connector. Once the automobile bears a head-on collision to generate supernormal shaft direction impact load, the safety pin and the non-metal safety retainer ring as the safety connectors can be cut off, the metal safety retainer ring as the safety connector can be pressed into a corresponding safety retainer ring groove, making the spline pair generate the collapse. The impact energy is absorbed, and thereby, the personal casualty can be avoided or reduced.
