Problems solved by technology

Although various tests were performed by changing both the mounting directions of the parts and the assembly order of the parts, a combination of the mounting directions and the assembly order of the parts that can realize automatic and continuous assembly of the travel stopper could not be found
[0012] In addition, due to the specific geometry of the components of the travel stop and the inherent clearances in the travel stop formed by these components, in actual use, the rattling of the parts will eventually generate noise; In vehicles with restraints, this noise can affect the comfort of the driver and passengers

Abstract

The invention relates to a hydraulic shock absorber for a suspension system and to the corresponding improved hydraulic stop, the hydraulic shock absorber comprising a tubular shell, a tubular body (20) and an axially movable, reciprocating rod provided with an elastomeric, stroke-limiting annular element. The stroke-limiting element (6) comprises a retention ring (7), a locking ring (8) and a sealing ring (9), the retention ring (7) partially enclosing the locking ring (8) and defining, together with the locking ring (8), a groove (91) for accommodating the sealing ring (9).

Description

technical field [0001] The present invention relates to an improved hydraulic shock absorber for vehicle suspensions, such as for damping vibrations in the suspension of motor vehicles and the like. More particularly, the present invention relates to an improved hydraulic shock absorber including an improved hydraulic stop, and a corresponding improved hydraulic stop. Background technique [0002] The shock absorber of the vehicle suspension mainly includes a telescoping device having a reciprocating rod installed along an inner cylinder in a housing of the telescoping device. The telescoping device has on its outer side an end connectable to the vehicle structure and an opposite end connectable to a suspension arm of the vehicle. [0003] When the movement of the vehicle suspension relative to the vehicle body causes the reciprocating rod to reciprocate, fluid communication is achieved between the inner cylinder and the housing through at least one fluid passage valve moun...
