Definitions
- the invention relates to wheeled vehicles of high cross-country ability, able to reliably navigate rough terrain, including land, water, sand, ice and swamp, as well as to overcome hills and pits, and can be widely used in wheeled cross-country vehicles.
- a light wheel all-terrain vehicle with an onboard turn comprising a frame, a steering and a power transmission, in which, according to the invention, the power transmission consists of an engine, a clutch, a gearbox, a chain drive, a differential, a differential lock mechanism, two brakes, two semi-axles, four on-board chain transmissions, allowing to transmit torque from the engine to the left and right driving wheels independently of each other and to create a difference in their angular speeds due to braking of the axles ["Light wheeled all-terrain vehicle with on-board rotation" RU134484U1, ⁇ 60 ⁇ 9 / 00; 11/20/2013] [1].
- a disadvantage of the known all-terrain vehicle is the low reliability caused by the use of chain transmissions for its onboard turning, which under heavy loads during on-board turning of the all-terrain vehicle can lead to chain breaking.
- the closest in technical essence is an all-terrain vehicle containing a body, a hollow frame, an internal combustion engine with an intake manifold, a transmission including a gearbox, drive shafts, wheels with low-pressure tires, a tire pressure regulation system, and an on-board braking control system ["Everywhere and that shvydyuka all the way” UA117376C2 B60F3 / 00; B60G17 / 04; B60G21 / 06; B60C23 / 10; 07/26/2018) [2].
- the control system of the known all-terrain vehicle side braking contains shafts with sprockets connected by chain transmissions with sprockets mounted on shafts connected to wheels with low pressure tires.
- a disadvantage of the known all-terrain vehicle is also the low reliability caused by the use of chain transmissions for its onboard turning, which under heavy loads during the onboard turning of the all-terrain vehicle can lead to rupture of the chains.
- an onboard braking control system for an all-terrain vehicle that contains chain transmissions does not allow the use of a more powerful engine, since chain transmissions cannot provide high reliability to a more powerful all-terrain vehicle.
- the technical problem to which the invention is directed is to increase the reliability of the all-terrain vehicle.
- the on-board braking control system for an all-terrain vehicle contains on-axis differential gears and wheel gears symmetrically located between the front and rear pairs of wheels, on the axles of the cross-wheel differential gears there are brake mechanisms of the left and right sides of the hydraulic brake circuits of the left and right sides connected to the working hydraulic cylinders of the left and right sides for braking one of the sides of the all-terrain vehicle when turning, and on the axles of the wheel gears, wheels with tires fixed to the bearing assemblies on the hollow frame, with cross-axle differentials Special gearboxes are kinematically connected to the drive shafts of the front and rear axles of the all-terrain vehicle with the engine through the
- cross-country braking control system uses cross-axle differential gears and wheel gears containing more powerful gears, reliable transmission of torque from the engine gearbox through the drive shafts to the center differential gears, the axes of which are connected to the brake mechanisms, is ensured and further through the wheel gears to the wheel shafts, significantly increases the reliability of the all-terrain vehicle, especially in off-road conditions.
- the on-board braking control system of the vehicle which contains gears, allows the use of a more powerful engine to increase the power of the all-terrain vehicle.
- FIG. 1 shows an all-terrain vehicle, front view, axonometry.
- FIG. 2 shows a kinematic diagram of an all-terrain vehicle braking control system.
- FIG. 3 shows a diagram of a tire pressure control system of an all-terrain vehicle.
- the all-terrain vehicle (Fig. 1-3) contains a body 1, a hollow frame 2, an internal combustion engine 3 with an intake manifold 4, a transmission including a gearbox 5, drive shafts 6 and 7, wheels 8 with low-pressure tires 9, and a pressure control system in tires 9 wheels 8, as well as an all-terrain vehicle control system with onboard braking.
- the all-terrain vehicle control system for side braking (Fig. 2) contains symmetrically located between the front and rear pairs of wheels 8, the cross-axle differential gears 10 and the wheel gears 11.
- Cross-axle differential gears 10 are kinematically connected by drive shafts 6 and 7 of the front and rear axles of the all-terrain vehicle with the engine 3 through the gearbox 5.
- the body 1 of the all-terrain vehicle is made of composite materials.
- the system of regulating the pressure in the tires of the wheels of an all-terrain vehicle contains a hollow frame 2 made with an internal circuit 18 of a closed circuit connected to a source of supply of working air and with all tires 9 of the wheels 8.
- a turbocharger 19 of the engine 3 with an intake manifold 4 of an all-terrain vehicle is used to supply clean atmospheric working air.
- the intake manifold 4 of the engine 3, connecting the turbocharger 19 and the all-terrain vehicle 3, is equipped with a shutter 21 and connected on one side through a valve 22 to the internal circuit 19 of the closed loop of the hollow frame 2 and to all tires 9 of the wheels 8, and on the other hand is connected through the valve 23 and filter 24 with atmosphere.
- the pressure of clean atmospheric working air is increased or decreased in the inner line 19 of the closed loop of the hollow frame 2 and in the tires 9 of the wheels 8, depending on the terrain.
- torque with a distribution of 50: 50% (forward and backward) from the gearbox 5 is transmitted to the front and rear cross-axle differential gears 10, and then through the front and rear wheel gears 11 it is transmitted to the axles fixed in the bearing assemblies 18, and front and rear wheels 8 mounted on these axles.
- the driver moves the left lever towards himself, while the working cylinder of the left side 16 is pressed, as a result of which the brake forces are transmitted to the front and rear wheels 8 of the left side through the hydraulic brake circuit of the left side 14 and the brake mechanisms of the left side 12.
- the torque is reliably transmitted to the starboard side through the front and rear cross-axle differential gears 10, the front and rear wheel gears 11 and their shafts to the right side wheels 8, which begin to rotate faster than the left side wheels 8, due to which the all-terrain vehicle turns to the left.
- the pressure in the low-pressure tires is regulated by the tire pressure regulation system of the wheels of the all-terrain vehicle.
- the shutter 21 is always normally open, and the valves 22 and 23 are closed.
- the clean atmospheric working air after the turbocharger 20 through the open valve 22 enters the inner line 19 of the closed loop of the hollow frame 2, from where it is redistributed to the tires 9 of the wheels 8, and clean air from the atmosphere enters the engine 3 through the open valve 23 and the filter 24.
- the flap 21 opens and the valves 22 and 23 are simultaneously closed.
- an active system is used, in which, when the engine 3 is running, the valve 22 is opened and due to rarefaction in the intake manifold 4, clean atmospheric air from the inner line of the closed circuit 19 of the hollow frame 2 enters the engine 3 for further combustion.
- a quick change in tire pressure of 9 wheels 8 allows you to quickly respond to changes in terrain, which increases the reliability of the off-road vehicle.
- the claimed all-terrain vehicle provides a significant increase in its reliability during operation, especially on the roads.
- the claimed all-terrain vehicle has a high cross-country ability and is able to reliably navigate rough terrain, including on land, water, sand, ice and swamp, as well as to overcome hills and pits.
