Unless defined otherwise, all technical terms used in the examples of the present application have the same meaning as commonly understood by one of ordinary skill in the art. In order to facilitate understanding of a usage scenario of a control arm on a rear suspension of a vehicle provided in an embodiment of the present application, some technical terms involved in the embodiment of the present application are described below.

Vehicle suspension system: the assembly of the frame and all force-transmitting connecting devices in front of the axle (or wheel). The function of the device is to transmit vertical reaction force (supporting force), longitudinal reaction force (traction force and braking force) and lateral reaction force acting on wheels by a road surface and moment caused by the reaction forces to a frame so as to ensure normal running of the automobile.

A vehicle suspension system comprising at least: elastic element, shock absorber and direction power transmission element. Vehicle suspension systems may include front and rear suspensions, depending on the position in the vehicle.

An elastic element: and a member for relieving the up-and-down vibration of the vehicle caused by the unevenness of the ground. For example, a spring. The spring can take place deformation after receiving ground impact, and then can avoid the automobile body to appear vibrating by a wide margin. However, the spring tends to rebound after being deformed, and the vehicle body tends to vibrate continuously. Therefore, the elastic element is generally installed in parallel with the shock absorber to suppress the back-and-forth oscillation of the spring by the damping action of the shock absorber.

The shock absorber: and the component is used for reducing the vibration of the vehicle frame and the vehicle body. For example, a hydraulic damper. The general principle of a hydraulic damper is described here by way of example for a damper: when the frame and the axle reciprocate relatively and the piston inside the shock absorber reciprocates inside the cylinder, oil inside the shock absorber casing flows repeatedly from one cavity to the other cavity via some narrow holes. At the moment, the friction between the hole wall and the oil liquid and the liquid intramolecular friction form damping force to vibration, so that the vibration energy of the vehicle body and the vehicle frame is converted into heat energy to be absorbed by the oil liquid and the shock absorber shell, and then the heat energy is dissipated into the atmosphere, and the vibration is reduced.

Guiding the force transfer element: and a member for transmitting various forces acting on the wheel to the vehicle body while ensuring the wheel to move in a certain trajectory. In particular, an upper control arm and a lower control arm may be included.

The upper control arm of the rear suspension according to the embodiment of the present application means a control arm mounted on the rear suspension of the vehicle and located on the upper side.

In order to make the technical solutions and advantages of the present application clearer, the following will describe the embodiments of the present application in further detail with reference to the accompanying drawings.

Specifically, in fig. 1, the two bushes 2 are in the mounted state, that is, the two bushes 2 are mounted on both ends of the control arm body 1 through the bush mounting portions 12, respectively. With continued reference to fig. 2, fig. 2 illustrates an exploded view of a control arm on a rear suspension of a vehicle according to an embodiment of the present application, with the bushing 2 in an uninstalled state in fig. 2. As can be understood by referring to fig. 1 and 2, in the actual use of the control arm on the rear suspension, the two bushings 2 may be respectively mounted on the control arm body 1 by means of the bushing mounting portions 12, and then the two bushings 2 are respectively connected with other components of the vehicle (specifically, a vehicle steering knuckle and a vehicle subframe), so that the control arm body may be connected with other components of the vehicle, and then the control arm on the rear suspension may play a role in guiding and transmitting.

Alternatively, the portion of the cross-sectional shape that is T-shaped may be the portion of the main body extension 11 that is required to withstand the larger bending moment. In specific implementation, the bending resistance (such as bending strength) required to be achieved by each part in the transverse direction of the control arm on the rear suspension of the vehicle can be analyzed and calculated by means of Computer Aided Engineering (CAE for short) according to the axle load of the whole vehicle, and the part (such as the part required to achieve the preset threshold value for the bending strength) required to bear larger bending moment in the control arm body is determined through topological operation. By providing these portions with a T-shaped cross-sectional shape in the extending direction (wherein the wider side in the cross-sectional shape is the upper side of the control arm body), structural reinforcement of these portions can be achieved. The reinforced control arm body has higher transverse bearing capacity.
