Embodiment Construction

[0026] figure 1 Shown is a shock absorber 1 with a damping adjustment system 2 , which is actuated so that it can be moved back and forth along a movement axis 4 in a damper tube 6 , which is formed as an outer cylinder. A damping medium 8 in the form of damping oil is located in the outer cylinder 6 . The damping adjustment system 2 has a housing 10 , a guide tube 12 arranged in the housing 10 and formed as a pole tube, and an armature 14 guided in the pole tube 12 so that it is movable along the displacement axis 4 . The armature 14 is guided such that it can move back and forth within the lumen 16 of the pole tube 12 between the bottom 18 of the pole tube 12 and the support surface 20 .

[0027] In the intermediate space between the housing 10 and the pole tube 12 is arranged a magnetic coil 22 capable of electromagnetically actuating the armature 14 when it is energized. Between the housing 10 and the damping tube 6 there is an outer space 24 which, like the inner space ...

Abstract

The application provides a damping adjusting system having a guide tube which is arranged in an outer housing and which comprises a lateral outer wall. The interior of the guide tube being delimited at the end face by a base part. The guide tube can also have a magnet coil; an electromagnetically movable armature which is guided in the guide tube along a movement axis; an exterior which surrounds the outer housing; and a ventilation bore which connects the interior to the exterior and which is guided through the base part and the outer housing. The ventilation bore has two interconnected sections. A first section is guided through the base part and the first section has a first opening arranged on the base part on the interior side and a second opening arranged on the lateral outer wall, and a second section is guided through the outer housing.

Description

technical field [0001] The invention relates to a damping adjustment system according to the preamble of claim 1 and to a shock absorber with a damping valve unit designed as a damping adjustment system. Background technique [0002] Adjustable damping systems or damping adjustment systems are currently available in many vehicles and offer motorists a high degree of driving comfort and increased driving safety. To this end, the suspension controller's control unit can use data, especially from acceleration and distance sensors for each wheel, to individually adjust the damping force within milliseconds. . In this way, the occupants are protected as much as possible from road disturbances and the shock absorbers are activated in such a way that the movement of the body is stabilized in the best possible manner. [0003] In this case, the shock absorber usually has a shock tube or outer cylinder in which an integrated adjustment system moves back and forth in the shock fluid...
