Problems solved by technology

[0004] The spline shaft end (A7) and the drive shaft yoke (A2) are locked together with the nut (A1) in the middle of the existing universal joint transmission shaft. There is no relative movement. The vibration of the engine is absorbed by the deformation of the rubber, and there is pull-off and risk of excessive deformation and tearing

Abstract

The invention relates to a novel universal joint transmission shaft intermediate support. The novel universal joint transmission shaft intermediate support comprises a transmission shaft fork, a first sealing ring, a snap spring, a cylindrical roller bearing, an outer framework, an inner framework with a rubber sleeve, a second sealing ring and a spline shaft end. The spline shaft end and a first transmission shaft are welded together. The transmission shaft fork is assembled with a cross shaft and connected with a second transmission shaft. An enough space needs to be reserved for spline fit so that displacement generated by vibration of an engine can be absorbed, the situation that a spline fixedly abuts against the transmission shaft fork and is pulled away from the transmission shaft fork is avoided, and the strength of the spline is taken into account. According to the novel universal joint transmission shaft intermediate support, the transmission shaft fork is fixed, the spline shaft end can slide on the transmission shaft fork in the axial direction, axial displacement caused by vibration of the engine is absorbed, and tearing or pull off phenomenon caused by large rubber sleeve movement amount due to vibration of the engine is avoided. The novel universal joint transmission shaft intermediate support is suitable for the mode that a universal joint transmission shaft is connected with a gearbox through a flange face or a flexible universal joint.

Description

technical field [0001] The invention relates to the field of intermediate supports of automobile universal joint transmission shafts, in particular to a novel intermediate support of universal joint transmission shafts. Background technique [0002] In the universal joint transmission shaft structure, usually when the total length of a single transmission shaft is greater than 1.5 meters, it will be fixed in the middle of the transmission shaft, and the transmission shaft will be divided into two sections to increase the critical speed of the transmission shaft and reduce the vibration caused by resonance. Caused failures such as drive shaft fracture. The current intermediate support structure of the transmission shaft is usually composed of an outer skeleton, an inner skeleton, an intermediate rubber bush, an intermediate bearing, an oil seal, and a shaft joint of the transmission shaft. Among them, the transmission shaft joint can be divided into single welding type and d...
