Description

Technical Field

[0001] The utility model relates to the technical field of control arm equipment, in particular to a control arm for a front suspension of an automobile. Background Art

[0002] The control arm (triangle arm) on the automobile suspension is a guide and force transmission element of the automobile suspension system. It transmits various forces acting on the wheel to the body and ensures that the wheel moves along a certain trajectory. The control arm assembly consists of three parts: the housing, the ball pin and the arm shaft. The wheel and the body are elastically connected together through the suspension ball pin (hinge) or the arm shaft bushing. The control arm assembly (including the suspension ball pin and arm shaft connected thereto) should have sufficient rigidity, strength and service life.

[0003] The application number is CN202320882233.3, which discloses a control arm assembly for a front suspension of an automobile, including a main body mechanism, a ball pin assembly mechanism and a rear bushing mechanism, wherein the ball pin assembly mechanism is located at the lower end of the main body mechanism, and the rear bushing mechanism is located at the upper right end of the main body mechanism, wherein the main body mechanism includes a body, a weight-reducing hole, a first connecting through hole, a front liner and an avoidance hole, wherein the outer wall of the weight-reducing hole is fixedly connected to the inside of the body, the outer wall of the avoidance hole is fixedly connected to the inside of the body, the bottom of the first connecting through hole is fixedly connected to the top of the body, the outer wall of the front liner is movably connected to the inner wall of the first connecting through hole, the inner wall of the rubber tube is movably connected to the outer wall of the front liner, and the outer wall of the rubber tube is movably connected to the inner wall of the first connecting through hole. The control arm assembly for the front suspension of an automobile, through the structure of the weight-reducing hole and the avoidance hole, is convenient for the control arm assembly to be subjected to less pressure during actual use.

[0004] The above document discloses a control arm assembly for a front suspension of an automobile with the following defects: when the control arm swings, the control arm will drive the wheel assembly to swing together. Since brakes and other components are installed on the wheels, the wheels are generally heavy. The control arm is not provided with a connection structure with the wheel assembly, and the two are not stably fixed, so it is impossible to ensure that the control arm can drive the wheel to rotate normally.

[0005] It can be seen from this that the existing control arm assembly does not have the function of strengthening the connection with the wheel assembly, and it is necessary to improve the existing deficiencies and provide a function that can strengthen the connection with the wheel assembly.
