Abstract
Pneumatic mattress track system to be used as a construction element in vehicles. A soft air filled mattress formed for instance by mattress bags (5) is automatically rolled out and serves as running surface and means of propulsion. The hull (1) of the system is disposed over the mattress on an air cushion (4) and thus without mechanical friction. The mattress formed for instance by the mattress bags (5) is not air tight and filled once, but it is filled automatically when it runs under the system hull (1) and is kept under constant pressure in the carrying position. The air for the mattress is supplied from the air cushion (4) through inlet orifices (7) provided in the wall of the mattress facing the hull (1). The main area of use is transport in difficult and vulnerable terrain.
Claims8
A pneumatic mattress track system used as a construction element of a vehicle, comprising a hull, front and rear roller means, endless, hollow mattress means running around said roller means, said mattress means having a plurality of discrete bag arrangements, each bag arrangement having a band surface facing the hull during entire operation of the system, the band surface having at least one opening for feeding a pressurized gas into the bag arrangement, a gas cushion space being defined between the hull and the band surfaces of the plurality of bag arrangements, the gas cushion space having a substantially thin configuration to enable to use a bottom of the hull and the band surfaces as the only sealing means for the gas cushion space, the gas being fed into the gas cushion space through a plurality of orifices in the bottom of the hull, a number of the orifices being at least equal to a number of the bag arrangements upon which the system rests during the operation.
