Problems solved by technology

However, this leads to a possible impact of the guide element on the piston rod during certain actuations of the shock absorber, for example during transverse actuation, resulting in undesired noise formation.
However, reducing the play on the piston rod, for example by means of an interference fit that would reduce such noise formation, would lead to increased friction between the piston rod and the guide element

Embodiment Construction

[0021] exist figure 1 A chassis shock absorber 10' for a vehicle is shown in . The chassis damper 10' has a damper cylinder 12', in which a piston is movably mounted, which is coupled to a piston rod 14' protruding from the damper cylinder 12'. A first fastening element 16' is arranged on the damper cylinder 12'. A second fastening element is arranged on the piston rod 14'. The chassis damper is mounted in the vehicle with these fastening elements, one fastening element being mounted on the movable chassis element and the other fastening element being fixedly mounted to the vehicle.

[0022] If the components connected to the chassis damper 10' are moved relative to each other, the piston moves in the longitudinal direction L' in the damper cylinder 12'. The movement of the piston can be damped by a damping medium, for example oil, in the damping cylinder 12 ′, and thus the movement of the connected components relative to one another can be damped.

[0023] In order to pre...

Abstract

In a guide element (28) for a buffer spring (20) in a chassis shock absorber (20) which is slidably mounted on a piston rod (14) of the chassis shock absorber (10), with a guide (32) that has a cylindrical receiving space (36) for the piston rod (14) and a receptacle (34) for an end (26) of the buffer spring (20), there is provided on the guide (32) at least one spring element (42) which extends into the receiving space (36) and can be resiliently seated against the piston rod (14).

Description

technical field [0001] The invention relates to a guide element for a buffer stop spring of a chassis shock absorber, which is movably mounted on a piston rod of the chassis shock absorber, the guide element having a guide and a buffer stop Receptacle for the end of the retaining spring, the guide has a cylindrical receptacle for the piston rod. Background technique [0002] The chassis shock absorbers in vehicles have damper stop springs. The damping stop spring is installed in the cylinder of the chassis shock absorber and can cooperate with a stop element arranged on the piston rod, and thus damps at the end face of the cylinder or at the end stop of the piston or piston rod Collision on the stop face of the end face. [0003] The buffer stop spring is fastened, for example, on the cylinder side and is supported on the piston rod with a guide element. This is achieved by clamping the buffer stop spring inside the cylinder. Alternatively, the damper stop spring can be ...
