Independent suspension system for mining vehicle

摘要

An independent suspension for a steerable wheel of a mining vehicle and a suspension unit. The wheel of the mining vehicle is mounted to a frame via the suspension unit alone. The suspension unit comprises an outer tube attached to the frame and an inner tube arranged partly inside the outer tube, the hub of the wheel being attached to the lower part of the inner tube. The inner tube may move in a longitudinal direction as required by suspension movements and, further, the inner tube may be rotated about its longitudinal axis to steer the wheel. The suspension unit is further provided with hydropneumatic members for producing suspension movement and dampening.
