RU170878U1 - Articulated two-link high-cross-country vehicle snow and swamp vehicle on ultra-low pressure tires with a wheel arrangement of 16x16 - Google Patents

Abstract

The utility model relates to transport engineering, in particular to multi-purpose transport vehicles on ultra-low pressure tires, designed for use in various conditions, having a high level of patency due to the low mover pressure on the ground, high traction and traction characteristics, and designed for transporting goods and people in especially difficult climatic conditions (swamp, snow virgin lands, open water obstacles). The task to be solved is to increase vehicle performance when driving on soils with low bearing capacity, increased payload. The technical result is an increase in the number of drive wheels, the use of the layout according to a two-link articulated scheme with a rotary hitch. This technical result is achieved in that to the front link of the machine, which has a wheel formula 8x8, by means of a rotary hitch, a second link is connected, which also has an 8x8 wheel arrangement. Torque to the second link is transmitted from the power plant installed on the first link. The rotary hitch has three degrees of freedom, allowing you to change the position of the links relative to each other in horizontal and vertical planes and to carry out mutual rotation about the longitudinal axis.

Description

The utility model relates to transport engineering, in particular to multi-purpose transport vehicles on ultra-low pressure tires, designed for use in various conditions, having a high level of patency due to the low mover pressure on the ground, high traction and traction characteristics, and designed for transporting goods and people in especially difficult climatic conditions (swamp, virgin snow, open water obstacles).

Known snow and swamp vehicles on ultra-low pressure tires with a wheel arrangement of 8x8: "Shaman" manufactured by Avtoros LLC (www.avtoros.info); The "Prospector" of Vorobyov Design Bureau (www.komz.ru), the 4x4 Mamontenok snow and swamp vehicle with the breaking frame of Arktictrans LLC (arctictrans.ru). Snow-and-ice vehicles “Shaman” and “Staratel” consist of a displacement casing, a power plant installed in it, transmitting torque to the drive wheels with ultra-low pressure tires through mechanical gears (gearboxes, driveshafts, final drives) and have a wheel arrangement of 8x8. The Mamontenok snow and swamp vehicle has a 4x4 wheel arrangement, consists of a breaking frame, which has one degree of freedom (for turning in a horizontal plane), on which a power unit, a gearbox, a transfer case, a cabin, a front drive axle with a suspension are mounted and installed ultra-low pressure tires; a cargo platform, a rear drive axle with suspension and installed ultra-low pressure tires are installed on the rear of the frame.

The closest to the claimed technical essence and the achieved result, selected as a prototype, is the Shaman snow and swamp vehicle Avtoros LLC, consisting of a displacement casing mounted on the chassis, which is a wheel with ultra-low pressure tires mounted on an independent hydropneumatic double wishbone suspension double wishbones. The torque from the internal combustion engine installed in the front of the machine body is transmitted through a mechanical gearbox, the driveshaft to the five-way transfer case, which distributes torque to the main gears and then to the wheel gearboxes, which rotate the machine wheel.

The disadvantages of the prototype in relation to the proposed snow and swamp path include lower throughput due to fewer drive wheels, lower carrying capacity, passenger capacity, the absence of a rotary hitch that provides additional degrees of freedom and increases the geometric throughput of the machine

The problem to be solved is to increase the maneuverability of the car when driving on soils with low bearing capacity, and increasing the carrying capacity.

The technical result is an increase in the number of driving wheels, the use of a layout according to a two-link articulated scheme with a rotary hitch.

This technical result is achieved by the fact that to the front link of the machine, which has an 8x8 wheel arrangement, a second link is connected by means of a rotary hitch device, which also has an 8x8 wheel arrangement. Torque to the second link is transmitted from the power plant installed on the first link. The rotary hitch has three degrees of freedom, allowing you to change the position of the links relative to each other in horizontal and vertical planes and to carry out mutual rotation about the longitudinal axis.

Figure 1 shows the front link of the machine 1 with the installed power plant 2. The second link 3 is connected to the first by means of a rotary hitch 4. The mover of the machine is sixteen drive wheels 5 with installed ultra-low pressure tires.

Figure 2 shows various options for the position of the links relative to each other (a - rotation in the horizontal plane, b - rotation in the vertical plane, c - rotation relative to the longitudinal axis).

Claims (1)

Snow and swamp vehicle on ultra-low pressure tires with a 16 × 16 wheel arrangement, characterized in that it has two driving links interconnected by a rotary coupling device, each of which has an 8 × 8 wheel arrangement, the torque is transmitted to the second link propulsors from the power plant mounted on the first link, the hitch has three degrees of freedom, allowing mutual rotation of the links in three planes, while the front link can be operated separately from the rear, disconnecting rotary hitch.
