Abstract:
A piston damper assembly (10) includes a piston damper (12) and a relative velocity sensor (14). The piston damper includes a damper body (16), a piston rod (18), and a dust tube (20) which is attached to the piston rod. The relative velocity sensor incudes an axially extending first magnet (24) supported by the dust tube, a flux collector (28), and a first sensor coil (30). The flux collector is supported by the dust tube, includes an axially-extending first prong (34) in axially-extending proximity with the first magnet, includes an axially-extending second prong (36), and includes a joining member (38) connecting the first and second prongs. The first sensor coil surrounds the joining member and/or one of the first and second prongs. A piston-damper dust tube subassembly (42) includes the dust tube and the relative velocity sensor.

Abstract:
A damper device (50) comprising a first mode having a first level of damping, a second mode having a second level of damping corresponding to a predetermined function, a sensor system (84) having a first output corresponding to a normal position and a second output corresponding to an end stop approaching position, and a control system (88) operable for receiving the first output and the second output and executing the first mode and the second mode. The damper device (50) is operable in the first mode when the control system (88) receives the first output and is operable in the second mode when the control system (88) receives the second output. A controllable suspension system (48) comprising a damper device (50), a magnetic probe, a sensor system (84) comprising at least one position sensor (214) operable for sensing the position of the magnetic probe, and a control system (88) electronically connected to the sensor system (84) and the damper device (50), wherein the control system (88) is operable for receiving an output from the sensor system (84) and executing a predetermined function to control the damper device (50). Electric signals are supplied to the damper device (50) from the control system (88) during system operation to provide damping sufficient to prevent end stop collisions.

Abstract:
The invention relates to an arrangement for a gas spring. The arrangement comprises a cylinder (1). At its one end, this is delimited by a fixed end wall (2), and at its other end there is a first guide (3) sealed against the inner wall of the cylinder (1) and against a piston rod (4) capable of axial movement within the cylinder (1). The piston rod (4) has a second guide (8) mounted in such a way as to be capable of sliding against the inner wall. An annular piston (9) sealed against the inner wall and against the piston rod (4) is mounted on the piston rod (4) between the guides (3; 8) in such a way that it is free to slide. This divides the inner space of the cylinder (1) into a first and a second part space (12; 13). In an initial position, in which the gas spring is unaffected, there is present in the first part space (12) a pressure which is greater than the pressure present in the second part space (13). The annular piston (9) is retained between the guides (3; 8) through the effect of the pressure acting upon, on the one hand, one surface (9a) of the annular piston (9) and, on the other hand, the other surface (9b) of the annular piston (9) and the end surface (4a) of the piston rod (4).
Abstract:
The apparatus (20) comprises a pressure cylinder (40) forming a working chamber (42) having first and second portions operable to store damping fluid. The apparatus (20) further comprises the first valve (84) for controlling the flow of damping fluid between the first and second portions of the working chamber (42) during compression of the apparatus (20). In addition, the apparatus (20) further comprises a pressure chamber (90) in fluid communication with the first portion of the working chamber and the first valve (84). A solenoid (124) is also provided for regulating the flow of damping fluid between the pressure chamber and the second portion of the working chamber. A second valve (86) is further provided for controlling the flow of damping fluid between the first and second portions of the working chamber (42) during rebound of the apparatus (20).
