Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a compression type hydraulic vehicle body suspension with high reliability and excellent shock absorption performance. Background Art

[0002] In recent years, with the upgrading of consumption, non-load-bearing hard-core SUVs have become more and more popular. Therefore, the use of body suspension parts used to connect the body and the frame (chassis beam) has increased. Figure 1 and Figure 2 As shown in the figure, the traditional body suspension adopts a separate structure design with upper suspension cushion, lower suspension cushion and center tube. This design has the problem of assembly rotation during the actual assembly process, resulting in poor assembly consistency. Since the center tube and the suspension of the body suspension are separate structures, there is relative rotation between the suspension and the center tube diameter during the assembly and locking process, which affects the assembly effect. It affects the NVH effect of the whole vehicle and the assembly effect during the manufacturing process.
