The present disclosure relates to a damper system for a vehicle. The damper system may have an electrically adjustable hydraulic shock absorber including a rod guide assembly, a pressure tube, a reserve tube and an electromechanical valve. The electromechanical valve may be disposed in a valve cavity within the shock absorber. An integrated electronic system may be included which has a power drive electronics. The power drive electronics is electrically coupled to the electromechanical valve. The integrated electronic system is disposed along an axis parallel to a longitudinal axis of the pressure tube, and at a location radially outwardly of the pressure tube adjacent the rod guide assembly.

A damper system and method for a vehicle includes a shock absorber and a damper module. The shock absorber includes a plurality of digital valves. The shock absorber is operable at one of multiple damping states based on a valve state of the digital valves. The damper module is coupled to each of the digital valves and controls each of the digital valves to a desired state based on a damper setting. The damper module determines a target damping state, where the target state is one of the multiple damping states. The damper module performs a switch operation to control the valve state of the plurality of digital valves to a given desired state when the target damping state is different from a present damping state.

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.

Disclosed is a method for measuring height in a vehicle by determining a distance between a vehicle chassis and a vehicle axle or parts connected thereto. In the method, a first device (12) with a first transmitter (13) and a first receiver (14) and a second device (15) with a second transmitter (16) and a second receiver (17) interact. In particular, the first transmitter (13) produces an electromagnetic field, and the second receiver (17) detects the electromagnetic field. The second device (15) with the second transmitter (16) produces a signal from the detected field and transmits the signal, which correlates with the distance from the first transmitter (13) to the second receiver (17). The first device (12) with the first receiver (14) receives the signal. A system, an electronically controlled pneumatic suspension, an electronic control unit, and a vehicle are also disclosed.

A damper system for a vehicle comprises an electrically adjustable hydraulic shock absorber and a damper control module. The damper control module is disposed with and coupled to with the shock absorber. The damper control module determines a target damping state of the shock absorber based on data received from a plurality of sensors. Furthermore, the damper control module controls the shock absorber, such that the shock absorber operates at the target damping state.

Disclosed is a chassis component (1, 38) having a measuring device (9) for determining a relative position of two chassis components connected movably with one another. For example, a first chassis component is a joint (2) with at least one rotation axis (8) and a second chassis component is a structural component (3), the structural component (3) being mounted by means of the joint (2) so that it can pivot around the rotation axis (8) of the joint (2). The measuring device (9) has a signal emitter (13) and a sensor device (10, 28) with a signal receiver (21), where the sensor device (10, 28) is arranged on the structural component (3) and the signal emitter (13) is arranged on the joint (2). To improve an arrangement of the sensor device (10, 28) on the structural component (3), the sensor device (10, 28) extends through a through-opening (11).

A shock assembly is disclosed. The assembly includes a damper chamber having an outer wall with a first inner diameter (ID). A secondary chamber within the damper chamber, the secondary chamber comprising an exterior wall with an external diameter (ED) less than the ID of the outer wall to form an annular region therebetween. A damping piston coupled to a piston rod, the damping piston disposed in the secondary chamber and axially movable relative to the secondary chamber, the damping piston to bifurcate the secondary chamber into a compression side and a rebound side. A valve to control a flow of a working fluid between the annular region and the secondary chamber.
