Abstract
A vehicle includes a wheel assembly, a chassis, and a damper assembly coupling the wheel assembly to the chassis. The damper assembly includes a housing including a wall defining a first aperture and a second aperture, a first tubular member coupled to the housing, a second tubular member slidably coupled to the housing and extending between the wall and the first tubular member, a piston coupled to the second tubular member, the piston engaging an inner surface of the wall and an outer surface of the first tubular member, and a conduit fluidly coupling the first aperture and the second aperture.
Claims20
A vehicle, comprising:
- a wheel assembly;
- a chassis;
- and
- a damper assembly coupling the wheel assembly to the chassis, the damper assembly comprising:
- a housing including a wall defining a first aperture and a second aperture;
- a first tubular member coupled to the housing;
- a second tubular member slidably coupled to the housing and extending between the wall and the first tubular member;
- a piston coupled to the second tubular member, the piston engaging an inner surface of the wall and an outer surface of the first tubular member;
- and
- a conduit fluidly coupling the first aperture and the second aperture.
A vehicle, comprising:
- a wheel assembly;
- a chassis;
- and
- a damper assembly coupling the wheel assembly to the chassis, the damper assembly comprising:
- a housing including a wall that defines an inner volume, a plurality of first apertures, a second aperture, a third aperture, and a fourth aperture;
- a piston disposed within the inner volume and configured to move along a length of the housing;
- a first conduit fluidly coupling the first apertures to the second aperture;
- and
- a second conduit fluidly coupling the third aperture to the fourth aperture.
A vehicle, comprising:
- a wheel assembly;
- a chassis;
- and
- a damper assembly coupling the wheel assembly to the chassis, the damper assembly comprising:
- a tubular member;
- a housing that receives the tubular member, the housing defining a first pair of apertures that are part of a first flow path and a second pair of apertures that are part of a second flow path, a volume between the housing and the tubular member defining an annular chamber;
- and
- a piston positioned within the annular chamber,
- wherein the damper assembly is configured to provide a damping force that varies based on a position of the piston within the annular chamber.
