Problems solved by technology

As a result, disadvantageous situations arise because of the thermal effect on the damping tube caused by the welding process, especially if the working piston is guided directly on the inside of the damping tube
Here, it should be noted that even if the welding process introduces minimal heat, for example by using laser radiation, the thermal effect of the damping tube is still so high that the permanent operation of the vibration damper will likely be interrupted, especially in the event of thermal deformations or effects on the structure in the case of
Even if only surface damage occurs on the inner side of the damping tube, the long-lasting operation of the vibration damper cannot be guaranteed

Embodiment Construction

[0019] figure 1 with figure 2 The lower part of the vibration damper 1 , which forms part of a wheel attached to a vehicle, is shown in half section. The vibration damper 1 has a damper tube 10 in which a working piston 11 is guided along a longitudinal axis 13 . The inner side 12 of the damping tube 10 is used for guiding the working piston 11 . Due to the guiding task of the inner side 12 , it is necessary for the inner side 12 to be non-destructive, especially with regard to dimensional accuracy and surface quality. The working piston 11 is connected to a piston rod 23 and the piston rod 23 is used for attachment to a vehicle structure.

[0020] To produce the attachment of the vibration damper 1 to the wheels of the vehicle, among other components, a receiving fork 16 is used, which is attached to the lower end of the vibration damper 1 and, for example, A containment fork 16 is connected to the journal. The accommodating fork 16 is located on a reinforcing sleeve 15...

Abstract

The invention relates to a vibration damper (1), in particular for a chassis of a vehicle, comprising a damping tube (10) and comprising along a longitudinal axis on the inner side (12) of said damping tube (10) (13) Guided working piston (11). A reinforcing sleeve (15) is arranged on the outer side (14) of the damping tube (10), on which a accommodating fork (16) for attachment to the chassis can be arranged. A reinforcement sleeve (15) is delimited in the direction of the longitudinal axis by an outer peripheral edge (17). According to the invention, the sealing element ( 18 ) surrounding the outer side ( 14 ) of the damping tube ( 10 ) is accommodated in the reinforcement sleeve ( 15 ) in the region of the peripheral edge ( 17 ), wherein the peripheral edge ( 17 ) has a surrounding A plastically deformable reshaped section (19) of the sealing element (18). The invention also relates to a method for arranging a reinforcing sleeve (15) on the outer side (14) of said damping tube (10).

Description

technical field [0001] The invention relates to a vibration damper, in particular for a chassis of a vehicle, comprising a damping tube and a working piston guided along a longitudinal axis on the inner side of the damping tube, and a reinforcement sleeve arranged on the outer side of the damping tube On the reinforcing sleeve, a receptive fork for attachment to the chassis can be arranged and the reinforcing sleeve is delimited in the direction of the longitudinal axis by a peripheral edge. Background technique [0002] In order to create a mechanical reinforcement for holding the containment fork, the arrangement of reinforcing sleeves on the outside of the damping tube is known. Due to the limited wall thickness, the wall of the damping tube cannot in principle be loaded mechanically enough to arrange the receiving fork directly on the outside of the damping tube, so reinforcing sleeves are provided on the damping tube for mechanical reinforcement. Furthermore, in a mann...
