Driven steered wheel units for independent suspension

The wheel hub reductions are designed for the assembly on the swing arms of the suspension of the chassis frame of military vehicle. They have an in-built one-stage reduction gear of the rotation speed. The wheel carrier made from casted steel creates supporting part of the units. Grooved pin is pressed and welded in the wheel carrier on which the reduction gear is fixed by means of the connecting screws for the drum of KNOTT brake. The pinion gear drives the reduction gear. Connecting hub with flange is fixed on its grooved end. The cast made from aluminium alloy creates cover of the reduction housing. Brake drum of the KNOTT brake is closed by means of the drum cover that is also made from the aluminium alloy. The drum cover is modified for the air distribution – the units are designed for the central system of the tyre blowing during the driving. The reduction housing is partly filled by fully synthetic oil for lubrication and cooling of the reduction gear set. Parts of the front wheel hub reduction suspension are created aside others by ball pin placed on the upper part of the wheel carrier – for the suspension into the upper suspension arm. They further consist of the king pin with axial bearing and horizontal pin for connecting of the wheel hub reduction to the bottom front arm of the suspension to the vehicle frame by means of rubber silent blocks. The horizontal pin has grease filling for continuous lubrication of the king pin of the wheel hub reduction by means of the pressure pistons.
