Description

Technical Field

[0001] The utility model relates to the technical field of bracket equipment, in particular to a rear control arm bracket for an automobile. Background Art

[0002] Some models have subframes, and 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 perspective 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 shape, requiring multi-layer plate welding, resulting in insufficient strength of the body beam, increased weight, increased costs, and difficulties in mass production precision and quality control.

[0003] The application number is CN201922420349.1, which discloses a mounting bracket for a control arm, including a frame beam connecting bracket and a control arm supporting bracket, wherein the frame beam connecting bracket is U-shaped, and the frame beam connecting bracket includes a left vertical plate, a bottom plate and a right vertical plate, and the tops of the left vertical plate and the right vertical plate are respectively extended outwards with a beam flange, and the frame beam connecting bracket is fixedly connected to the frame beam through the beam flange, and the control arm supporting bracket is in an inverted L-shape, and the control arm supporting bracket includes a control arm supporting bracket vertical plate and a control arm supporting bracket cross plate, and the upper left side of the control arm supporting bracket vertical plate is fixed to the outer side of the right vertical plate, and 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 can be rotatably connected in the U-shaped structure. The utility model has a simple structure, is lightweight, and has a low design cost, and 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] The above document discloses a control arm mounting bracket having the following defects: when the mounting bracket is in use, when the rear control arm drives the wheel to swing and tilt, the two rear control arms need to synchronously drive the two wheels to rotate at the same frequency to make the vehicle run more stably. The bracket does not connect the two rear control arms and cannot ensure the synchronization of the two rear control arms.

[0005] It can be seen from this that the existing control arm mounting bracket does not have the function of making the two rear control arms swing synchronously, and it is necessary to improve the existing deficiencies and provide a function that can make the two rear control arms swing synchronously.
