Technical Field
[0001] This utility model relates to the field of commercial vehicle chassis bracket technology, specifically a combined bracket for commercial vehicle chassis. Background Technology
[0002] Chinese utility model patent CN216842875U discloses a combined chassis support for commercial vehicles, comprising a chassis support, a connecting block fixedly connected to the front of the chassis support, a first magnet fixedly installed in the middle part of the front of the connecting block, a shock absorber fixedly installed along the edge of the front of the connecting block, a shock absorber spring fixedly installed inside the shock absorber, a telescopic column movably sleeved on the left side of the shock absorber, a crash plate fixedly installed on the left side of the telescopic column, a second magnet fixedly installed in the middle part of the right side of the crash plate, mounting seats fixedly connected to the front and back of the chassis support, a stud threadedly connected to the upper surface of the mounting seat, a screw head fixedly connected to the upper surface of the stud, the stud having an inner cavity, and an inner column fixedly connected to the inner cavity of the stud.
[0003] The above-mentioned technical solution uses shock absorbers, shock absorber springs, and telescopic columns at both ends of the chassis bracket to dampen impacts. However, since the shock absorbers and anti-collision plates are located on the outside of the chassis bracket, they are prone to bending when impacted and shaking during vibrations, increasing vehicle noise and reducing their damping effect. Furthermore, the use of inner columns inside the studs reduces the strength of the studs, thus affecting the stability of the chassis bracket and resulting in low practicality.
[0004] Therefore, this utility model provides a combined bracket for commercial vehicle chassis. Utility Model Content
