    In addition, the vibrations generated from the control arm and the differential gear are transmitted to the body because the crossmember cannot absorb the vibration more effectively, and as the vibration is transmitted to the body, the riding comfort is lowered and the quality of the car is deteriorated. There were various problems such as poor stability.
    That is, in the conventional rear wheel drive suspension system, since the control arm and the differential gear are attached to the cross member via the bushing, the vibration generated from the differential gear is not dispersed, but the vibration is transmitted to the body so that the vibration is transmitted to the body. There are various problems such as deterioration and stability deterioration.
    The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to disperse the vibration generated by the differential gear to effectively dissipate or mitigate the vibration, thereby improving the riding comfort and ensuring stability. To provide a rear wheel drive suspension that can be.
    In order to achieve the above object, the rear wheel drive suspension device according to the present invention includes a control arm for controlling a wheel, a cross member mounted in a transverse direction of a vehicle so as to connect the control arm, and a skeleton in the longitudinal direction of the vehicle body. Rear wheel drive suspension system consisting of a frame for holding a frame, a body cross member for holding a frame in a lateral direction of the vehicle body, and a differential gear that gives a differential rotational speed to the left and right wheels against a difference in rotation generated by driving conditions. The bracket member for connecting the body cross member and the differential gear via a bush so that a part of the vibration generated in the deflection gear is transmitted to the body cross member and extinguishes. The bracket member is fixed to the bracket member. Some other vibrations generated by the differential gear are transmitted to the cross member to mediate the bush. And first and second torque tubes connecting the differential gear and the cross member.
    According to the rear wheel drive suspension according to the present invention, the differential gear is supported by the body cross member and the cross member at three support points through the bush so that the vibration generated from the differential gear is distributed to the cross member and the body cross member. By being extinguished, the vibration can be more efficiently alleviated or eliminated, thereby improving the riding comfort and securing stability.
