Also disclosed is a corresponding sensor unit (10) for a roll stabilizer (1) of the aforementioned type.

A chassis component for a wheel suspension which has a strut arrangement with at least one strut which is in the form of a profile component with an open cross-section. The at least one strut has a profile base and two wall sections that extend away from the profile base. An articulation point is provided, at least at one end of the strut, for receiving two joint components movably connected to one another, namely, a first joint component having a spherical joint body and a second joint component that rotatably and/or pivotably holds the joint body. In the area of the at least one articulation point, the wall sections have first and second joint accommodation apertures arranged opposite one another. A cylindrical sleeve is pressed in between the first joint accommodation aperture and the second joint accommodation aperture and keeps the opposite wall sections apart from one another.

A shock absorber for a vehicle having a damper and a first and second springs mounted coaxially around the damper and a preload adjuster for partially compressing at least one of the springs independently of the compression stroke. In one embodiment the preload adjuster is remotely controllable. In another embodiment the shock absorber includes an additional mechanism for preloading at least one of the springs.

A joint (10) with first and second joint components (12, 26; 19) are movably connected to one another. The first joint component (12, 26) has a spherical joint body (14, 28) and the second joint component (19) rotatably and pivotably holds the joint body (14, 28). A sensor device, for determining the position of the first and second joint components (12, 26; 19) relative to one another, is arranged on the joint (10). The sensor device has at least one sensor element (21, 31) which can be integrated in a housing (18) that is produced by an assembly overmolding process. The joint housing (18) forms the second joint component (19) in which the joint body (14, 28) is directly supported.

A simple and robust suspension arrangement is provided for taking into account different suspension modes without the need for excessive sensoring or electronics. The novel suspension arrangement includes a first suspension element, which directly suspends the object to the frame, and a second suspension element, which suspends the object to the frame through a magnetic coupling between the object and the second suspension element. The magnetic coupling provides a magnetic coupling force (F.sub.h) to act as a threshold such that the suspension arrangement is designed to magnetically decouple the second suspen-sion element from the object when the excitation force (F.sub.e) transmitted be-tween the frame and the object exceeds the magnetic coupling force (F.sub.h).

The present disclosure relates to a system for control of front and/or rear suspensions of a bicycle. The system comprises at least one sensor and one control unit. The at least one sensor is connected to the control unit and the control unit is configured to receive information from the sensor, determine a ride state of the bicycle from the information and send a suspension setting signal to the front and/or the rear suspension corresponding to the ride state. The control unit is further configured to establish an event, the event comprising information about said ride state of the bicycle and a suspension setting signal to the front and/or the rear suspension corresponding to the ride state and defining a minimum duration in time for the event.
