Description

Technical Field

[0001] This utility model relates to the field of automotive parts, specifically to a detachable and lightweight control arm. Background Technology

[0002] During vehicle operation, the control arm is an important component of the vehicle's suspension system, typically used to connect the wheels to other parts of the vehicle body (such as the frame or chassis). Its main function is to control the movement trajectory of the wheels, ensuring the stability and comfort of the vehicle while driving.

[0003] Conventional control arms and bushings are connected by welding. Welding is susceptible to thermal deformation, making it difficult to guarantee the positional accuracy of the core. Furthermore, if the bushing is damaged, it cannot be replaced. Utility Model Content

[0020] Figure 3 This is a cross-sectional schematic diagram of one embodiment of the present invention. Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings: As shown in the figures, a detachable lightweight control arm includes an arm body 1, on which a bushing 2 is mounted, and a mounting hole 11 located on the arm body. A connector 3 includes a connecting rod 31 and a connecting ring 32. The bushing is mounted on the connecting ring. The connecting rod is threadedly connected to the mounting hole. An operating part 33 for holding a disassembly / reassembly tool is provided on the portion of the connecting rod protruding from the mounting hole. The disassembly / reassembly tool can be an external hex wrench. After holding the operating part with the disassembly / reassembly tool, the connecting rod can be easily rotated to remove it from the threaded mounting hole for easy replacement. The bushing can be mounted on the inner wall of the connecting ring using a press-fit method.

[0022] In this embodiment, as shown in the figure, the operating part is a protrusion provided on the circumferential outer wall of the connecting rod.

[0023] In this embodiment, as shown in the figure, the cross-section of the protrusion is a regular polygon. It can be designed as a regular hexagon or octagon, etc., depending on the actual situation.

[0024] In this embodiment, as shown in the figure, the arm body is made of cast aluminum. The original arm body was a top and bottom SPHC welded structure, which was large and heavy, and limited the connection between the arm body and the bushing to welding. Using an optimized cast aluminum machined arm body effectively solves the problems of uncontrollable tolerances in the welding of the arm body itself and uncontrollable installation dimensions due to thermal deformation after welding with the bushing, improving tolerance control by an internal order of magnitude. Using a cast aluminum arm body structure allows the entire control arm to have better mechanical properties, while reducing the overall weight by 30% compared to the original control arm. This will result in better vehicle handling, better acceleration performance, and better fuel economy.

[0025] In this embodiment, as shown in the figure, the connecting rod includes a first rod 311 and a second rod 312. The connecting ring has a C-shaped structure, with one end connected to the first rod and the other end connected to the second rod. The connecting ring has a C-shaped structure, with a bushing installed in the middle slot. The two ends connect the first rod and the second rod. When the first rod and the second rod are spread apart (using a wedge tool to insert into the gap between them), the bushing is inserted, making assembly and disassembly more convenient.

[0026] In this embodiment, as shown in the figure, a gap groove 313 is provided between the first rod and the second rod.

[0027] In this embodiment, as shown in the figure, a shim 314 is installed in the clearance groove. The structure of adding the shim ensures that the control arm provides sufficient friction force during vehicle operation to prevent the bushing from falling off.

[0028] In this embodiment, as shown in the figure, the bushing includes a rubber sleeve with an annular opening groove 211 on it, which serves as a buffer.

[0029] In this embodiment, as shown in the figure, the arm body is provided with a second mounting hole 12, and a second bushing 121 is press-fitted into the second mounting hole.
