The embodiment of the invention provides a rear non-independent integral axle suspension system. The rear non-independent integral axle suspension system comprises a rear axle, a shock absorber assembly and a control arm assembly. The two ends of the rear axle are connected with hub supports, and the shock absorber assemblies are connected to the hub supports. The control arm assembly comprises a V-shaped thrust rod and two lower longitudinal arms; the two lower trailing arms are arranged in the longitudinal direction of the automobile body and connected to the two ends of the rear axle, and the two lower trailing arms are located on the inner sides of the hub supports. The V-shaped thrust rod is arranged between the two lower trailing arms, and the V-shaped vertex of the V-shaped thrust rod is in flexible connection with the middle of the rear axle. In the embodiment of the invention, the suspension system is composed of the rear axle, the shock absorber assembly and the control arm assembly which are formed by hot gas bulging, the V-shaped thrust rod is mainly formed by cutting, bending and welding a round pipe, the process is simple and few, and forming is easy. Compared with a traditional five-connecting-rod and three-connecting-rod mechanism, a Panha rod is omitted, space and material cost are saved, and meanwhile the same lateral supporting performance is guaranteed through optimization of the control arm assembly.

This utility model discloses an adjustable chandelier balancer, including a mounting base, a winding wheel movably mounted within the mounting base, a cable wound on the winding wheel, a spring winding wheel mounted on one side of the winding wheel, and a spring mounting wheel movably mounted on the mounting base corresponding to the spring winding wheel. A constant force spring is wound on the spring mounting wheel, one end of which is fixed to the spring winding wheel. A gravity braking mechanism is also installed within the mounting base. When the chandelier is adjusted, the constant force spring provides a stable basic recovery force through an S-shaped winding method, while the gravity braking mechanism provides dynamically adjustable additional braking force, which is increased when pulling down and released when rising, finding a perfect balance point that matches the weight of the chandelier, thereby achieving dynamic balance throughout the entire stroke. This utility model greatly reduces the reliance on on-site fine adjustment of the spring preload, avoids the technical problems of chandelier rebound or slippage, is simple to operate, and provides consumers with a better user experience.
