Description

Technical Field

[0001] This utility model relates to the field of automotive component technology, and in particular to a control arm bracket. Background Technology

[0002] The control arm is a key component of a car's suspension system. Typically made of metal, it comes in various shapes such as A-frame or L-frame, with its ends connected to the body and wheel steering knuckles via ball joints or bushings. It acts as a guide, directing the wheels along a specific trajectory to ensure appropriate steering angles during cornering and smooth steering. It also transmits and cushions road impacts, braking forces, and driving forces, reducing direct impact on the vehicle body. Control arm brackets are used because they provide a stable mounting point and support structure for the control arm, precisely positioning it and maintaining the correct position and angle for proper function. They also enhance the stability and strength of the suspension system, preventing excessive deformation or displacement of the control arm under load, ensuring reliability and safety. Furthermore, they facilitate the installation, maintenance, and replacement of the control arm, improving maintenance efficiency and reducing complexity. Finally, they precisely limit and guide the movement of the control arm, optimizing vehicle handling, driving stability, and comfort, resulting in less body roll during cornering and smoother straight-line driving.

[0003] A search revealed a control arm mounting bracket in publication number CN211567577U, comprising a frame beam connecting bracket and a control arm support bracket. The frame beam connecting bracket is U-shaped and includes a left vertical plate, a base plate, and a right vertical plate. The top ends of the left and right vertical plates each have outwardly extending beam flanges. The frame beam connecting bracket is fixedly connected to the frame beam via these beam flanges. The control arm support bracket is inverted L-shape and includes a control arm support bracket vertical plate and a control arm support bracket horizontal plate. The upper left side of the control arm support bracket vertical plate is fixed to the outside of the right vertical plate. The control arm support bracket horizontal plate and the base plate of the frame beam connecting bracket form a horizontal U-shaped structure, within which the control arm is rotatably connected. This utility model has a simple structure, is lightweight, and has low design cost. It achieves the connection between the control arm and the vehicle body and solves the problem of the height difference between the control arm and the vehicle body. Although this application achieves a simple structure, is lightweight, has low design cost, achieves the connection between the control arm and the vehicle body and solves the problem of the height difference between the control arm and the vehicle body;

Reinforcing components, including reinforcing plates 4, reinforcing blocks 5, reinforcing blocks 6, and reinforcing ribs 8, are installed on the outer wall of the bracket body 1. These components strengthen the bracket body 1, improving its overall strength and load-bearing capacity, ensuring it can withstand significant mechanical loads during use. The connection between reinforcing block 5 and the bracket body 1 provides stable support for reinforcing plate 4, enhancing the bracket's stability. A fixing plate 9 is installed on one side of the outer wall of the bracket body 1, containing a limiting groove 17 and a slidingly connected limiting block 18. The limiting groove 17 is used for precise limiting... The movement of the limiting block 18 ensures that the fixed plate 9 and its connecting plate 11 remain in the predetermined position during adjustment, avoiding unnecessary offset or loosening. The cooperation between the connecting plate 11 and the mounting boss 12 further enhances the installation stability of the control arm. The positioning component achieves precise positioning through the limiting hole 10 and the mounting hole 13 on the connecting plate 11 using the positioning bolt 14. The positioning bolt 14 is fastened to the fixing bolt 16 by threads, ensuring that the connecting parts do not loosen during fixing, and the shim 15 reduces friction and improves connection stability. The sliding connection function of the positioning bolt 14 makes the adjustment process more flexible and can adapt to the needs of different installation angles and positions. Through these mutually cooperating designs, the control arm bracket can provide precise and stable adjustment functions while maintaining strong load-bearing capacity, ensuring the reliability and safety of the control arm during operation.
