Problems solved by technology

[0004] The control arm of the front suspension of the automobile is connected to the vehicle body through the rubber bushing components at both ends. In order to effectively control the vibration caused by the excitation from the uneven road surface, it is hoped that the rubber bushing components have greater damping. However, the commonly used rubber bushings It is difficult for the components to provide the required large damping, which affects the handling and comfort of the vehicle
In addition, the front and rear suspension control arms are connected to the vehicle frame with rubber bushing components. On the premise of ensuring longitudinal flexibility, the lateral stiffness of the vehicle's front suspension cannot be effectively improved, thereby affecting the operational stability of the vehicle.

Embodiment Construction

[0021] Such as Figure 1 to Figure 6 As shown, the front suspension control arm of the automobile is a sheet metal part stamped and formed from a sheet metal, and includes a control arm main body 6. At the rear connection end F of the frame, a flange 3 is arranged at the edge between each two ends, and a ball stud assembly 4 is fixed with a bolt 1 on the connection end G of the control arm main body 6 and the steering knuckle; the control arm main body 6 is on its A flange hole 7 is opened on the front connection end E of the vehicle frame and a ball stud assembly 4 is fixed therein. The ball stud assembly 4 is located in the flange hole 7 and is interference fit with the control arm main body 6; A fixing groove 9 is arranged on the rear connection end F of the vehicle frame and a hydraulic bushing 5 is fixed therein. The hydraulic bushing 5 is welded in the fixing groove 9 through a fixing shaft 8 .

[0022] The control arm main body 6 is provided with a reinforcing rib 2 at...

Abstract

The invention relates to a vehicle front suspension control arm which comprises a control arm main body, wherein the control arm main body is provided with a connecting end with a steering knuckle, a front connecting end with a vehicle frame and a rear connecting end with the vehicle frame, a ball head pin assembly is fixed at the connecting end with the steering knuckle through a bolt, a ball head pin assembly is fixed at the front connecting end with the vehicle frame, and a hydraulic lining is fixed at the rear connecting end with the vehicle frame. The front suspension control arm can improve the cushioning effect of a vehicle, thereby improving the drivability and the comfort of vehicle driving.

Description

technical field [0001] The invention relates to a front suspension system of an automobile, in particular to a front suspension control arm in the automobile front suspension system. Background technique [0002] The control arm of the front suspension of the car belongs to the suspension guide part, which connects the wheel and the body, plays the role of transmitting the force and moment between the wheel and the body, and ensures that the wheel bounces relative to the body with a certain trajectory. [0003] At present, in the structure of the front suspension system of most vehicles, the connection and installation of the front suspension control arm of the car to the vehicle body and the wheel is a three-terminal connection, that is, one end of the front suspension control arm is connected to the wheel, and the other two connected to the body. Such as Figure 7 As shown, the automobile front suspension control arm includes a control arm main body 6, which has a connect...
