Description

Technical Field

[0001] The utility model relates to the technical field of control arm mounting brackets, in particular to a rear mounting bracket for a front suspension lower control arm. Background Art

[0002] The suspension system is an important part of the vehicle, which has a great impact on the vehicle's ride smoothness and handling stability. The control arm, as the guide and force transmission element of the vehicle suspension system, transmits various forces acting on the wheel to the body, while ensuring that the wheel moves along a certain trajectory. The control arm can be directly installed on the subframe, which is relatively simple and convenient to install. However, due to limitations of space or cost and other factors, some models do not have a subframe structure, and the control arm assembly needs to be installed on the body beam. From the analysis of the hard points of the whole vehicle, there is a large height difference between the control arm and the body beam, and the control arm requires a large installation plane, resulting in a complex body structure and complex shape. Multi-layer plate welding is required, which causes insufficient strength of the body beam, increased weight, increased costs, and difficulties in mass production precision and quality control.

[0003] The existing patent (Announcement No.: CN211567577U) discloses a mounting bracket for a control arm, including a frame beam connecting bracket and a control arm supporting bracket, the frame beam connecting bracket is U-shaped, the frame beam connecting bracket includes a left vertical plate, a bottom plate and a right vertical plate, the tops of the left vertical plate and the right vertical plate are respectively extended outwards with a beam flange, the frame beam connecting bracket is fixedly connected to the frame beam through the beam flange, the control arm supporting bracket is in an inverted L-shape, the control arm supporting bracket includes a control arm supporting bracket vertical plate and a control arm supporting bracket cross plate, the upper left side of the control arm supporting bracket vertical plate is fixed to the outer side of the right vertical plate, the control arm supporting bracket cross plate and the bottom plate of the frame beam connecting bracket form a horizontal U-shaped structure, and the control arm is rotatably connected in the U-shaped structure. The utility model has a simple structure, is lightweight, and has a low design cost, realizes the connection of the control arm with the vehicle body and solves the problem of the height difference between the control arm and the vehicle body.

[0004] In the above patent technology, although the frame beam connecting bracket is U-shaped and the tops on both sides extend outward to provide beam flanges to provide a support surface for the upper end of the control arm, and the beam flanges are connected to the frame beam in a reliable surface contact connection, it is U-shaped and extends to both sides in an inverted "X" shape, so that the tension generated by the up and down swinging of the control arm during the driving of the vehicle may pull the frame beam mounting bracket, causing the beam flanges to be subjected to greater force, resulting in deformation due to pulling, affecting the stability of the structure. Therefore, a rear mounting bracket for the lower control arm of the front suspension is proposed. Utility Model Content
