A motor (M1) is provided with a hollow rotor shaft (3), an output shaft (T) inserted into the rotor shaft (3) and connected to an inner periphery of one end of the rotor shaft (3), and a detecting device which detects a torsion angle of the output shaft va...

An active wheel suspension for suspending a wheel assembly (12,14) from a sprung body of a wheeled vehicle (10), and adapted to permit a centre (68) of the wheel assembly (12,14) to move relative to the sprung body through a jounce and rebound travel and d...

An actuator (10) for an active suspension system includes an armature (16) and a housing (18) enclosing an interior. The interior has a volume that varies in response to movement of the armature (16). A wall of the housing (18) forms a first aperture (30) ...

The present invention provides a stabilizer apparatus for a vehicle which can improve the responsiveness of output torque of a motor-driven actuator to current flowing through an electric motor during periods in which the current decreases. An electronic c...

An electromagnetic suspension apparatus for an automotive vehicle employs an electromagnetic actuator interposed between a sprung mass and an unsprung mass and arranged in parallel with a suspension spring element, and an electric motor built in the electr...

Vehicle suspension device, ensuring control of vertical travel between a suspended mass and an unsprung mass, comprising an elastic linkage (1) mounted between the suspended mass and the unsprung mass, said elastic linkage (1) comprising a spring (4) and c...

The suspension unit (1) is mounted between the wheels (2) and bodywork (3) using a vertical sliding wheel connection (7). It consists of a helical spring (4) and reversible electric jack (5) which are connected in parallel. The jack uses a rack and pinion ...
