[0002] The core function of the bracket connector in the rear suspension system is to connect various components of the rear suspension, ensuring the stable operation of the entire suspension system.

[0003] There are three main types of common bracket connectors. First, there are subframe suspension brackets, which connect the subframe to the vehicle body and install the suspension. Some designs use a combination of connecting plates and sleeves to improve the overall rigidity of the brackets and the subframe itself. Second, there are shock absorber brackets, used to fix the shock absorbers. Some light trucks combine them with rear stabilizer bar support brackets, using a main body, pads, and other structures to connect to the frame and install the shock absorbers. Third, there are spring seat brackets, mainly used to connect and fix the springs, preventing spring displacement or vibration and ensuring the normal operation of the springs.

[0004] Currently, most of the bracket connectors used in automotive rear suspension systems are made of steel and are fixed to the vehicle body and suspension components by welding or bolts. However, the lack of a positioning structure during installation necessitates multiple adjustments, resulting in low positioning accuracy, low installation efficiency, and the significant weight of the steel components, which is detrimental to vehicle weight reduction.

A plastic-coated inner frame 204 is installed at the center of the rubber body 203. The upper end cover 205 is riveted to the upper side inside the aluminum bracket body 1 by a riveting process.

[0018] There are two connecting ear plates 2. The two connecting ear plates 2 are respectively inclined and mounted on the left and right sides of the aluminum bracket body 1. The top of the two connecting ear plates 2 are inclined and have mounting holes 21. There are two positioning pins 3, which are fixedly installed on the front side of the two connecting ear plates 2 respectively.

[0019] In the initial state, the bushing assembly 201 is installed inside the aluminum bracket body 1, wherein the outer frame 202 cooperates with the aluminum bracket body 1, the rubber body 203 and the plastic-coated inner frame 204 play a buffering and shock absorption role, and the upper end cover 205 is fixed to the upper side of the aluminum bracket body 1 by riveting process. During installation, the bracket is quickly aligned with the body and suspension components by cooperating with the two positioning pins 3 and the holes on the vehicle body.
