A SUV has the problem of body lateral vibration and steering wheel vibration during acceleration. By using the transfer path analysis, the axial derived force produced by the tripod constant velocity universal joint is the main excitation source. Then the fundamental cause of axial generation force is analyzed theoretically. It is concluded that the factors affecting the axial force include driving torque, included angle of transmission shaft, grease lubrication coefficient and ball joint form. And four improvement schemes are given. The research results show that, by reducing the included angle of the transmission shaft, the body lateral vibration is improve effectively and the measured vibration at the seat rail is reduced by 10dB.
