Abstract

The invention provides a universal-joint crossing shaft. The universal-joint crossing shaft comprises a cross-shaped universal-joint base body. The four tail ends of the universal-joint base body areprovided with ends. The universal-joint base body is internally provided with a longitudinal oil channel and a transverse oil channel. The longitudinal oil channel penetrates the center portion of theuniversal-joint base body and a pair of ends, in the longitudinal direction, of the universal-joint base body. The transverse oil channel penetrates the center portion of the universal-joint base body and a pair of ends, in the transverse direction, of the universal-joint base body. The ends are further provided with radial oil holes communicating with the longitudinal oil channel or the transverse oil channel. By means of the universal-joint crossing shaft, the flowing path, resistance and the oil consumption are reduced, the lubrication effect is improved, the clamping phenomenon, caused bydry friction, of a transmission shaft in the running process is reduced, automobile accidents are avoided, and the service life of a universal-joint crossing shaft assembly is prolonged.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a universal joint cross shaft. Background technique [0002] The universal joint cross shaft is the universal joint, which is a part that realizes variable-angle power transmission. It is used to change the position of the transmission axis direction. It is the "joint" part of the universal transmission device of the automobile drive system. The combination of the universal joint cross shaft and the transmission shaft is called the universal joint cross shaft transmission device. On vehicles with front-engine rear-wheel drive, the universal joint cross shaft transmission device is installed between the output shaft of the transmission and the input shaft of the drive axle final drive; while the vehicle with front-engine front-wheel drive omits the drive shaft, the cardan The joint cross shaft is installed between the front axle half shaft and the wheel, which is responsible for both dr...
