An active damper system for damping high-frequency vibration excitation of the vehicle body, includes a damper bearing to support a vehicle chassis component on the vehicle body, wherein the damper bearing includes a first bearing element for fastening to the vehicle body and a second bearing element for fastening to the vehicle chassis component; an active actuating element connecting the first and second bearing elements; a first acceleration sensor for measuring an acceleration of the vehicle body; a control unit connected to the acceleration sensor and receiving a vertical acceleration of the vehicle body as input variable from the acceleration sensor, wherein the control unit influences the active actuation element. The active damper system includes a second acceleration sensor arranged on the second bearing element.

A gas spring seal cap secured a first end member of a gas spring and damper assembly such that a substantially fluid-tight connection is formed therebetween. Seal cap includes a seal cap body with a first end surface portion and a second end surface portion. An electrical conductor extends through seal cap body that includes a first terminal end conductively accessible from along the first end surface portion and a second terminal end that is conductively accessible from along the second end surface portion of seal cap body. Electrical conductor includes a substantially impermeable portion having a substantially fluid-tight connection with seal cap body. The substantially impermeable portion of electrical conductor substantially inhibits fluid communication across seal cap body through electrical conductor. Gas spring and damper assemblies as well as methods of assembly are also included.

An arrangement for a sensor system for vehicles, in particular motor vehicles, for detecting the vehicle speed, the vehicle level and/or the state of the vehicle suspension, having a sensor for measuring the level of a point on a vehicle body and a vibration damper, the vibration damper comprising a first part and a second part which are movable relative to each other, and wherein the level sensor has an excitation coil, at least one receiver coil and at least one electrically conductive element, wherein the excitation coil and the at least one receiver coil are arranged on the second part of the vibration damper and the electrically conductive element is arranged on the first part of the vibration damper or the first part comprises or forms the electrically conductive element.

An airshock assembly is disclosed. The airshock assembly includes a shock absorber an airspring, and an air compressor assembly. The airspring is axially coupled with a portion of the shock absorber and used to modify a ride height of the shock absorber. The air compressor assembly is coupled with a portion of the shock absorber. The air compressor assembly is used to modify an air pressure in the airspring without requiring the airshock assembly to utilize an air reservoir.

An object of the present invention is to provide a shock absorber that can use a single bracket regardless of difference in thickness of a knuckle bracket. A shock absorber according to the present invention includes: a shock absorber main body having an outer shell and a rod movably inserted into the outer shell; a knuckle bracket attached to an outer circumference on a bottom end side of the outer shell; and a bracket including a curved piece curved along a circumferential direction of an outer circumference of the outer shell and an attachment piece extending from the curved piece and to which a mounting component is attached, the curved piece including a bracket attached to the outer shell by being welded to the outer circumference of the outer shell and within a range from a top end to a bottom end of the knuckle bracket in an axial direction of the outer shell.

A shock assembly includes a damper chamber; a piston rod received in the damper chamber; a damping piston connected to the piston rod, moveable within the damper chamber, and defining first and second chamber portions; an internal floating piston defining a third chamber portion, being disposed between the second and third chamber portions, and being axially moveable between first and second positions; a fluid received in the first and second chamber portions; a pressuring unit received in the third chamber portion; a magnetic element connected to the internal floating piston; first and second hall sensors configured to respectively provide first and second position readings of the internal floating piston based on a position of the magnetic element; and a processor communicatively connected to the first and second hall sensors and being configured to determine a position of the internal floating piston based on the first and second position readings.
