Abstract
An automotive drive shaft is used in a front drive transmission vehicle for transmitting rotary movement from the gearbox output shaft to the wheels with a constant velocity. This paper presents the kinematic model of ball joint and tripod joint with consideration of clearance and proposes a simplified dynamics model of the drive shaft. The simulation of the dynamics model is given by the measured data. Also, the abrasive wear of the ball type joint is tested on the experimental setup with consideration of full loading. The results show that the dynamics of the motion will be affected by the clearance when the loading changes its direction. The motion will be stable due to the damping. It can be found that the abrasive wear of ball joint largely depends on the relative sliding velocity from the experiments. This will probably affectthe dynamics performance and the impact force, which will also cause the other type of failures.
Highlights
An automotive drive shaft is used in a front drive transmission vehicle for transmitting rotary movement from the gearbox output shaft to the wheels with a constant velocity
The plunging tripod joint is close to the gearbox, while the ball joint is close to the wheel
As the drive shaft assembly is composed of three parts: a fixed ball type joint, a plunging type tripod joint, and a shaft, it is required to model the assembly in detail for the investigation of the dynamics performance
Summary
An automotive drive shaft is used in a front drive transmission vehicle for transmitting rotary movement from the gearbox output shaft to the wheels with a constant velocity. It is composed of three parts: a fixed type joint, plunging type joint, and intermediate shaft. Serveto et al [3] showed that the sixth component of the secondary torque generated by the ball joint model during torque transmission could produce acoustic beats with the vibration of the engine.
