Abstract
A high-pressure gas spring for vehicle suspension systems includes an integral gas damping system and an integral counter spring to reduce spring residual force at suspension rebound. The gas spring includes an inverted piston feature that reduces the overall length of the device. Additionally, there are other innovative features incorporated in the gas spring to improve performance, reduce cost and minimise weight.
Claims22
A vehicle suspension gas spring for mounting between a vehicle chassis and a vehicle wheel suspension member comprising:
- a cylinder closed at one end;
- a piston assembly slidably mounted within the cylinder and sealingly engaging with a bore of the cylinder to form a gastight seal between the piston and the cylinder bore;
- a piston rod attached to the piston and projecting outwardly of the cylinder, the piston rod passing through and being slidably mounted in an end cover of the cylinder;
- connector means for attachment of the cylinder to one of the vehicle chassis and the vehicle suspension member and for attachment of the piston rod to the other of the vehicle chassis and the vehicle suspension member;
- a gas working medium within the cylinder;
- and
- a first gas chamber formed by the swept volume of the cylinder and an associated second gas chamber communicating with the first gas chamber through a gas passageway which restricts the flow of gas therebetween.
