Description

Light suspension upper support assembly Technical Field The application relates to the technical field of automotive suspensions, in particular to an upper support assembly of a lightweight suspension. Background The conventional suspension upper support assembly usually adopts a metal structure, such as cast iron or steel brackets, and has higher strength but larger weight, so that the requirement of light weight of the new energy automobile is not met. In addition, existing suspension support structures often suffer from stress concentration during vibration transmission, affecting durability and ride comfort. At present, part of the light weight proposal adopts aluminum alloy to replace part of metal parts, but the problems that 1, the structure is complex, the traditional suspension support assembly is usually welded or bolted by adopting multiple layers of metal, so that the assembly is complex and the weight is difficult to further reduce, 2, the vibration reduction performance is insufficient, the combination mode of the rubber vibration reduction part and the metal framework is single, the relative displacement is easy to occur, the vibration reduction effect is influenced, 3, the stress distribution is uneven, the connection mode between the rubber body and the framework possibly causes local stress concentration, and the service life is reduced. Therefore, there is a need for a new lightweight suspension upper support assembly that optimizes damping performance and reduces overall weight while maintaining structural strength. Disclosure of utility model The utility model mainly aims at solving the problems of high weight, insufficient vibration damping performance and complex structure of the existing suspension upper support assembly and provides a lightweight suspension upper support assembly. The aim of the utility model is mainly achieved by the following scheme: The upper support assembly of the lightweight suspension comprises a support with hollow inner portions and openings at the upper end and the lower end, wherein a circle of first boss is arranged on the inner side wall of the support, the first boss divides the inner portion of the support into an upper installation cavity and a lower installation cavity, an rubber body is installed in the upper installation cavity, an outer skeleton is installed between the outer side wall of the rubber body and the inner side wall of the upper installation cavity, a first inner skeleton and a second inner skeleton are installed in the rubber body, an upper baffle is installed above the rubber body, a clamping groove for installing the upper baffle is formed in the top of the inner side wall of the upper installation cavity, the upper surfaces of the outer skeleton and the rubber body are in contact with the lower surface of the upper baffle, and through holes penetrating up and down are formed in the middle portions of the first boss, the rubber body, the first inner skeleton, the second inner skeleton and the upper baffle. Preferably, a circle of wing plates are arranged on the outer side wall of the bracket, and a plurality of bolts are vertically arranged on the wing plates. Preferably, the inner side wall of the outer framework is vertically provided with a guide sliding groove, and the outer side wall of the rubber body is provided with a guide sliding strip corresponding to the guide sliding groove. Preferably, a plurality of first limiting grooves are uniformly formed in the middle of the rubber body along the axis of the rubber body, and a plurality of first limiting plates corresponding to the first limiting grooves are uniformly formed in the outer side wall of the first inner framework along the axis of the rubber body. Preferably, the upper surface or/and the lower surface of the rubber body is/are uniformly provided with a plurality of second limiting grooves along the axis, and the outer side wall of the second inner framework is/are uniformly provided with a plurality of second limiting plates corresponding to the second limiting grooves along the axis. Preferably, one end of the second inner framework is provided with a circle of second boss, and the outer side wall of the second boss is contacted with the inner side wall of the rubber body. In summary, compared with the prior art, the utility model has the following beneficial technical effects: (1) According to the utility model, the weight of the suspension system is reduced through the bracket, the upper baffle, the first inner framework, the second inner framework, the outer framework and the rubber body, and the overall strength and the stability of the suspension system are improved; (2) According to the utility model, the installation flow is simplified through the guide sliding chute and the guide sliding strip, the first limit groove and the first limit plate, and the second limit groove and the second limit plate, so that the installation of each component is more accurate
