A damper system includes an electromagnetic damper 10 including: (i) an electromagnetic motor 46 which operates in association with motions of a sprung portion and an unsprung portion toward and away from each other; and (ii) an external circuit 90 which i...

An actuator apparatus controls a valve mechanism of a suspension system. The apparatus includes a valve actuating assembly and an adjuster assembly. The valve actuating assembly is operatively connected to the valve mechanism and is operable between at lea...

The invention relates to transportation machinery engineering and, in particular, to shock absorber systems in a suspension. It can be used in front and rear shock absorbers of automobiles and in other technical applications. [0002] The proposed technical ...

The hydraulic vibration damper for use in vehicles has an orifice plate (16) with linear characteristics which is mounted in the overflow channel (11). The pressure difference across the plate is regulated by a control valve (12). A throttle valve (13) is ...

The damping controller adjusts the damping of the vehicle according to the weight difference from a first wheel load to a second wheel load by using two damping coefficients. The damping controller adjusts the damping for different driving situations e.g. ...

The arrangement has a spring characterized by the maximum spring stroke with a level regulation device together with a height sensor for determining and setting the spring height between the two end positions. The damper is provided with a regulation devic...

The axle is held in bearings (8) on the ends of piston rods (4) protruding from the shock absorber cylinders (32,33). The pistons (3) slide in inner cylinders (34) which act as pistons in the shock absorber cylinders, and have piston rods connecting them t...

The method involves restricting the permissible change in current per time interval using a limit. Starting from a defined current value a different current limit is specified for a positive current change than for a negative current change. Both current l...
