FIELD: transport. SUBSTANCE: invention relates to automotive industry, particularly, to propulsors and may be used in construction of higher flotation vehicles. Proposed vehicle comprises main propulsors and extra auger-type propulsor. The latter is arranged under vehicle body, in its lengthwise axis, and controlled from driver cabin. With vehicle bottom adhered to soil, auger propulsor is used to drive the vehicle forward or backward unless stable contact of main propulsors with soil that allows to move in usual way. EFFECT: improved cross country capacity.
The invention relates to the transport industry, in particular to the propellers, and can be used in the manufacture of vehicles terrain. Self-propelled land vehicles terrain (hereafter TC), intended for driving in off-road conditions, mainly used wheeled or tracked propulsion. Off-road machine with caterpillar propulsion exceed wheeled cross-country, but when driving through deep ruts in the case hangs on the bottom, when the propellers are not touching the ground, both TC lose the ability to further independent movement. In such a situation, used tractor, if it is nearby, or winch, but to strengthen its cable required fixed support or TC greater mass than evacuated. In any case, the required output of the driver from the cab TS right into the mud. Given the conditions under which such vehicle may get stuck, this procedure is not very pleasant and can adversely affect health. In patents GB 2300842 (A) from 20.11.1996, B62D 57/036 and EN 2229997 C1 from 10.06.2004, B62D 57/036 presents the design of the vehicle, in which the propulsion ground screw machines are used. These machines are not widely used because they have low efficiency. Technical task saleemul the invention is to improve the patency of the self-propelled off-road vehicle subject relative comfort control. This goal is achieved by using an additional screw propulsion, located under the bottom of the vehicle along its longitudinal axis. This arrangement of the auger can be used not only for tracked vehicle terrain, but for the wheel. Hang TC on the bottom of the claimed device is connected by the driver without leaving the cockpit and rotating, moves the specified vehicle forward or backward in the direction of travel until the emergence of a stable contact of the main propulsion with the soil and the appearance of motion in the usual way. The short duration of use of the claimed device will not have a significant impact on the overall efficiency of the vehicle. In the inventive device can be used hollow speck, placed inside the drive shaft of the TC, or rod, in stowing retractable in a special niche in the bottom. The essence of the invention lies in the fact that to improve cross-propelled off-road vehicle use additional screw propulsion, located under the bottom along its longitudinal axis, which is operated by the driver from the cab. Hang TC on the bottom of the specified mover rotates, moves it forward or backward in the direction of travel until the emergence of a stable contact of the main propulsion with the soil and the appearance of movement on icnam way. Closest to the technical nature of the claimed invention are device proposed in patent SU 918162 And from 07.04.1982, B62D 57/00, B60F 3/00, WM 27/02 and SU 477033 And from 15.07.1975, B62D 57/00, using a combined propulsion containing crawler truck and auger, but this design is applicable only in TC with tracked vehicles and cannot be used for wheeled vehicles terrain. The technical result of the invention is to increase the patency of the self-propelled off-road vehicle. This technical result is achieved due to: - use in case of freezing TC on the bottom, additional screw propulsion, located under the bottom along its longitudinal axis, which allows to use it not only for tracked vehicle, but also for wheeled; - management of the specified device driver from the cab of the vehicle; - move the vehicle during the rotation of screw propulsion forward or backward in the direction of travel until the emergence of a stable contact of the main propulsion with the soil and the appearance of motion in the usual way. The device is designed to improve cross-propelled off-road vehicle due to the use, hang it on the bottom, additional screw propulsion, located under the bottom along its u who dolinoy axis and controlled by the driver from the cab. Screw propeller, rotating, moves the vehicle forward or backward in the direction of travel until the emergence of a stable contact of the main propulsion with the soil and the appearance of motion in the usual way. New the essential features of the claimed invention are: - improved terrain self-propelled off-road vehicle; - use for this purpose in case of freezing TC on the bottom, additional screw propulsion, located along the longitudinal axis under the bottom of the vehicle, which allows to use it not only for tracked vehicle, but also for wheeled; - management of the specified device driver from the cab of the vehicle; - moving vehicle during the rotation of screw propulsion forward or backward in the direction of travel until the emergence of a stable contact of the main propulsion with the soil and the appearance of motion in the usual way.
