摘 要：This paper aims to study an optimization design for reducing the vertical transmission force of ball-type constant velocity joint(CVJ),in order to improve vehicle idle *** the vertical transmission force of ball-type CVJ is measured by bench equipment so the correlation between vertical transmission force amplitude and excitation amplitude,loaded torque,shaft length is *** transmission force amplitude of ball-type CVJ has a positive correlation with excitation amplitude and loaded torque,while negative with shaft *** vertical transmission force resultant in wheel sides in idle condition is calculated and a vehicle experiment is proceeded to measure cabin floor vertical vibration acceleration in the same ***,an example is given to validate there is a strong linear correlation between the estimated values of vertical transmission force in wheel sides and the measured results of vehicle idle *** major factors affecting vertical transmission force of ball-type CVJ are *** transmission force can be restrained by using low friction grease,reducing ball-cage window interfere and enlarging ball pitch circle diameter(PCD)to optimize vehicle idle *** methods for vehicle idle vibration presented in this paper apply to both the oil-fueled and hybrid electric vehicles with engine.
