Hydraulic device for adjusting the minimum ground clearance of an automobile and a suspension damping device including such a device

摘要

The present invention comprises an automobile chassis (50) and an automobile suspension damping device (2) spring (60) comprising a piston (21) inserted through a first end (32) of an outer cylinder (10). It is related with the hydraulic device (1) which adjusts the minimum ground clearance of a motor vehicle suitable for inserting between. According to the present invention, the outer cylinder (10) has a folded portion (11) at the second end (34) opposite to the first end (32) of the outer cylinder (10), The folded portion defines the boundary of the annular groove (14) together with the outer cylinder (10), and the piston (21) can slide in the axial direction inside the annular groove (14). A suspension damping device (2) comprising such a device is also described. [Selection] Figure 1
