The invention relates to the field of transport engineering, namely to wheel propulsion terrain off-road, such as soils, swamps and snowy tundra.
The low permeability of the known vehicles is characterized in that the wheel when driving on liquefied highways that do not have special coatings that is buried down to more of a solid support base. Machine slows down and gets stuck. The driver for the resumption of the movement, to have a car to demcratic, put under the wheels of various solid lining, such as boards, etc, which are not held under the slipping wheel and take off from there, and then to resume the movement until the next failure that reduces the maneuverability of the vehicle.
The aim of the invention is to increase the maneuverability of the vehicle.
This object is achieved in that during the movement of the vehicle between the wheel and the road is closed undulating flexible membrane having an enlarged shape of the wheel and contacted him through the weight of the vehicle. The shell acts as a lining between the road and the wheel. The shell is a flexible design of variable stiffness along its length. Variable stiffness is achieved by periodically pri�proposed along the entire length inserted in the thickness of the flexible membrane in undulating areas, having an internal wave, turned to the wheel, flat springs. Increasing the contact area with the road and differentiation specific pressure acting on the road.
The work method is that when the internal interaction of the wheel with the wave of a flexible membrane under the weight of the vehicle occurs, the wave rectification of the flexible sheath. This leads, on the one hand, to increase the contact surface of the mover with the road, on the other hand, the differentiation of the specific pressure on the road precluding slippage of the flexible sheath.
Fig.1 shows a diagram of the base element of the vehicle wheels. It contains the tire 1, the rim 2, the hub 3, the side wheels 4, 5 discs closed shell 8, which is a flexible sheath wave form, in the internal wave which flooded flat spring 7.
The operation of the device is that during rotation of the inner wheel of his bus rolls inside the casing 8, thus there is straightening of the springs 7, which increases the area of contact of the shell with the road and increase the pressure on the road in places in the final and initial lengths of the springs.
Fig.2 shows a cross-section of the tire 1 of the wheels of the vehicle. The tire 1 on the periphery has a rim of the tire 6 wave form.
Work wheels �transport means, with bus with wavy rim, is that when rotated external reference wave of the rim due to the weight of the vehicle and decrease between wave thickness of the rim of the tire is pressed into the volume of the tire. This increases its internal pressure, leading to an increase of the contact surface with the road and differentiation of the specific pressure on the road. Adjusting the tire pressure and the thickness of the waves, it is possible to achieve the optimal propulsion of the vehicle.
When traveling on dirt roads the vehicle is fitted with propulsion, eliminates the formation of hollows, and also provides a seal point road, which is a positive factor for future traffic and leads to significant increase the service life of roads and vehicles.
The proposed propulsion of the vehicle can be used both in military technology, and the wide peaceful purposes.
