A suspension strut for a vehicle has an air spring unit and a damper unit. The damper unit has a damper tube, which extends into a rolling tube of the air spring unit. The damper tube has supporting geometries distributed over its circumference, against which supporting geometries a radially expanded end of the rolling tube is supported. In order to support the rolling tube on the supporting geometries of the damper tube, a torsion element is provided. The torsion element is arranged between the radially expanded end of the rolling tube and the supporting geometries of the damper tube. The torsion element forms a form fit with the supporting geometries for the purpose of torque transmission.

The present disclosure relates to an air spring apparatus for use with a cabin of a vehicle. The apparatus has an upper assembly, a lower assembly, a shock absorber, a bladder, a flexible bumper element and a control element. The shock absorber has a piston rod protruding therefrom and extending through the other one of the upper and lower assemblies. The bladder is attached to the upper and lower assemblies. The flexible bumper element is secured to the piston rod adjacent one of the upper and lower assemblies, and secured to the other one of the upper and lower assemblies. The control element is secured to the flexible bumper element at a first end, and to a valve at a second end, and controls operation of the valve. The flexible bumper element can flex in response to torsional or tilting forces experienced by the one of the upper and lower assemblies, to thus help to limit these forces from being imparted to the control element.

A suspension apparatus includes a main body, a first arm configured to support a wheel with respect to the main body, a second arm spaced apart from the first arm and having a guide rail, a shock absorber disposed between the second arm and the main body, a first support member disposed on one side of the shock absorber and rotatably connected to the main body, a second support member disposed on another side of the shock absorber and seated on the guide rail, and a driver configured to adjust a height of the main body by moving the second support member along the guide rail.

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 air spring assembly is disclosed. The air spring assembly includes an upper fork tube having a base lug on one end, a lower fork tube having an opening to receive the upper fork tube in a first axial end, and a fork tube gas seal to form a gas seal between the upper fork tube and the lower fork tube. A partial cartridge tube within a portion of the upper fork tube, the partial cartridge tube including a partial cartridge tube gas seal between an outer diameter (OD) of the partial cartridge tube and an inner diameter (ID) of the upper fork tube. An annular volume formed between the ID of the upper fork tube, the OD of the partial cartridge tube, the partial cartridge tube gas seal, and the base lug of the upper fork tube.
