Description

Tripod Constant Velocity Joint is used in driveshafts. The thrust force of the joint causes lateral vibration in front drive vehicles. To analyze the thrust force, we construct a detailed model based on multibody dynamics approach. This model includes all main parts of the joint as rigid bodies and considers all force components of contact and friction acting among these parts. In this model, we utilize a new contact modeling method of needle roller bearings for both more precise analysis and faster computation. By comparing the computational results with the experimental ones, we verify this model and clarify the main factors of 2nd and 3rd rotating order components of the thrust force. Moreover, we show the influence of the skew of needle rollers on the thrust force and evaluate the contribution of friction forces at each contact region to the thrust force.
