Abstract
The present disclosure relates to a suspension element for maintaining a wheel on a frame of a vehicle. The suspension element can be attached to the frame via a fixed support. The wheel can be mounted to an arm that is pivotably connected to the fixed support. A hydraulic strut resists a pivoting movement of the arm in relation to the fixed support. A pressure accumulator comprises a gas chamber and a fluid chamber separated by a diaphragm. The fluid chamber is in fluid connection with the hydraulic strut. A movement of the arm relative to the fixed support causes a change of pressure in the pressure accumulator. An independent suspension comprising two such suspension elements is also disclosed. The two suspension elements comprise extensions of the fixed support mounted on the frame so that two wheels are coaxial when mounted on the frame.
