Abstract

The invention relates to an automotive front Macpherson suspension and an automobile comprising the same. A control arm of the automotive front Macpherson suspension comprises a control arm body, a ball pin, a front frame bushing and a rear frame bushing, wherein the ball pin is positioned on the control arm body and is connected with a steering joint; the front frame bushing and the rear frame bushing are positioned on the control arm body and are connected with a frame; at least one of the front frame bushing and the rear frame bushing is made of a rubber material, and the radial rigidity is greater than the axial rigidity. Moreover, the invention also provides an arrangement relationship between key hard points of the control arm. According to the automotive front Macpherson suspension and the corresponding automobile, the rigidity characteristic of front and rear automobile reinforcing bushings on the control arm is perfectly designed, the relationship between the key hard points of the control arm is advantageously designed, the dynamic unbalance of a tire assembly when a vehicle runs at high speed and the vibration transferred to a driver by the frame are reduced, and the driving control and the driving comfort are improved.
