A non-drive dynamic stabilizer includes a damper and an actuator. The dynamic stabilizer provides multiple states of support to a solar tracker structure. These states may include 1) flexible movement and/or damping during normal operation (i.e. tracking) and/or 2) rigid or locked, whereby the dynamic stabilizer acts as a restraint. The dynamic stabilizer is actuated by a control system according to the real-time demands on the structure. Sensors to provide input to the control system may include wind speed sensors, wind direction sensors, snow sensors, vibration sensors and/or displacement sensors.

The present disclosure relates to a motor vehicle, comprising a leaf element, which is movably held at a bearing point of the motor vehicle, and an adjusting device by means of which the leaf element can be moved between a closed position, in which the leaf element closes an opening of the motor vehicle, and an open position, wherein the adjusting device comprises a spring component which, on the one hand, is coupled at least indirectly to the leaf element and, on the other hand, at least indirectly to a holding region of the motor vehicle, and which comprises a sleeve element and a piston element which is inserted into a sleeve interior of the sleeve element in certain regions and is displaceable relative to the sleeve element during the movement of the leaf element between the closed position and the open position. The spring component is designed as a spring strut and comprises a damping device for damping during the displacement of the piston element relative to the sleeve element during the movement of the leaf element between the open position and the closed position. A further aspect of the present disclosure relates to an adjusting device.

A blocking device for a shock absorber of a motor vehicle includes a first blocking member which has an insertion opening that is open-ended in a radial direction, for attachment of a piston rod of the shock absorber, and which has a receptacle. A second blocking member can be placed in a formfitting manner in the receptacle of the first blocking member in axial and radial directions to thereby close the insertion opening in the radial direction, while being held in the first blocking member.

A door component has a controllable damping device and contains a magnetorheological fluid. Two connection units are movable relative to one another. One of the two connection units is connected to a support structure and the other one to a pivotable door unit. The device damps a movement of the door unit between a closed position and an open position in a controlled manner by way of a control unit. The magnetorheological damping device has a piston unit and a cylinder unit surrounding the piston unit. The piston unit divides a cylinder volume into two chambers. The piston unit is equipped with a first one-way valve. The two chambers are connected together, via an external return channel equipped with at least one controllable magnetorheological damping valve, to form a one-way circuit. When the piston unit moves in and out, the magnetorheological fluid flows through the piston unit in the same flow direction.

A vehicle height adjustment device includes a changer, a detector, a vehicle height controller, and a malfunction detector. The changer is configured to change a relative position of a body of a vehicle relative to an axle of a wheel of the vehicle. The detector is configured to detect the relative position of the body of the vehicle relative to the axle of the wheel of the vehicle. The vehicle height controller is configured to control the changer based on a detection value detected by the detector to change the relative position to control a vehicle height, which is a height of the body. When the detection value detected by the detector changes by a predetermined amount or more in a predetermined period of time, the malfunction detector is configured to determine that there is a possibility of a malfunction occurring in the detector.

A vehicle height adjustment device includes a changer, a vehicle height controller, and a malfunction detector. The changer is configured to change a relative position of a body of a vehicle relative to an axle of a wheel of the vehicle. The vehicle height controller is configured to change the relative position based on a detection value detected by a detector configured to detect the relative position so as to control a vehicle height, which is a height of the body. The malfunction detector is configured to detect a malfunction in at least one of the changer and the detector, the malfunction causing the vehicle height controller to continue to control the vehicle height to increase.

A damper assembly includes a tubular member including a sidewall and a shoulder. The damper assembly includes a rod and a piston coupled to the rod. A secondary piston has a second contact surface, an opposing second surface, an inner cylindrical face defining a central aperture that receives the rod, and an outer cylindrical face. The opposing second surface includes one or more surface grooves, extending between the inner cylindrical face and the outer cylindrical face along the opposing second surface, and one or more bypass orifices disposed about the body member. The bypass orifices extend along the inner cylindrical face between the second contact surface and the opposing second surface. The secondary piston defines a channel extending between the inner cylindrical face and an outer periphery of the body member. The channel and bypass orifices form a fluid flow path when the piston contacts the secondary piston.

A suspension device includes a spring, a jack, a reservoir chamber which reserves the oil, a first pump, a second pump an opening and closing unit. The second pump is configured to cause the oil to flow into the housing chamber and to cause the oil to flow out from the housing chamber.
