Description

The invention relates to the field of transport engineering, and in particular to vehicles (all-terrain vehicles) of cross-country ability, used as passenger or freight vehicles when driving in off-road conditions, sand, wetlands, water obstacles, deep snow, mountainous terrain, light forests, rocky surfaces, as well as dirt roads and paved roads.

Famous off-road vehicles (all-terrain vehicles) have a number of disadvantages: large mass, large dimensions, limited movement on a slope of up to 20 °, low speeds of movement on rough terrain and afloat, low capacity, lack of comfort with universal vehicle design, limited patency, limited range of movement in the fuel reserve and single-fuel engines. As a result, well-known all-terrain vehicles cannot provide constant and reliable transport links between settlements located at great distances from each other, in year-round off-road conditions and in difficult climatic conditions, especially in the northern regions. Such vehicles are not suitable for long, long-distance traveling at high speeds on impassable roads, for example, for transporting people by public transport or geological exploration expeditions, or providing emergency assistance.

An all-terrain vehicle is known, including a waterproof housing, a running gear, an engine with a gearbox, and low pressure wheels, the running gear being made in the form of two final drives, each of which contains a caliper with a brake disc, which is connected via a shaft to the main angular gearbox, which in turn, through cardan shafts it is connected to angular gears that provide torque transmission to the wheels (see RF patent for utility model No. 53226, IPC B60F 3/00, publ. May 10, 2006).

The disadvantages of the known all-terrain vehicle are low operational reliability due to the use of separate onboard drives, since in the event of failure of one of them, further movement of the vehicle is impossible; the lack of a power structure for mounting the engine and mechanisms also reduce reliability; mechanical energy transfer using angular gears of equal angular gears reduce patency in off-road conditions; low pressure tires have low permissible speeds of 50-80 km / h, which limits the use of an all-terrain vehicle.

Also known is an all-terrain vehicle containing a primary jet engine and propulsion device, an aerodynamic lift of a secondary jet propulsion device and a wheel-blade propulsion device, with more than 90% of the mass of the all-terrain vehicle when moving is perceived by an aerodynamic lift using the effect of ekranole, and during movement through snow and ice up to 10% of the mass of the all-terrain vehicle is perceived by its runners (see application for the grant of a patent of the Russian Federation for invention No. 93048260, IPC B60F 3/00, B60V 1/14, publ. 11/27/1996).

The disadvantages of this all-terrain vehicle are its high cost, large mass, large dimensions and low passability (mountainous and rocky obstacles are not available), as well as environmental insecurity, since the use of jet engines that create strong noise and emit a huge amount of harmful products of aviation fuel combustion will cause the surrounding fauna and flora is a huge harm.

The closest technical solution, selected as a prototype, is a well-known amphibious all-terrain vehicle, containing a body riveted from sheets of light metals and divided into volumes, each of which is designed to perform certain functions, including for placing units, placing crew, heating the passenger compartment cabins equipped with berths, a bathroom and a kitchen, supported through an elastic suspension on wheels with low pressure tires, having an internal combustion engine as a power unit, while torque transmission from the engine to the main gears of the driving axles is carried out through the gearbox, cardan gears and transfer gears arranged in series, the first transfer gearbox having one forcibly disconnected output flange connected to a gearbox, the output flange of which is connected to a shaft that drives the propeller a screw, and the second output flange is connected to the input flange of the second transfer case having a two-stage transmission and a differential lock, output flanges to Torah flanges are connected with the input of the third and fourth transfer boxes having the same construction as the second transfer box (see. RF patent for utility model No. 64140, IPC B60F 3/00, publ. June 27, 2007).

A disadvantage of the well-known amphibious all-terrain vehicle is its low operational reliability, since the riveted hull made of light metal is a supporting structure and does not have structural elements for mounting and securing the engine and power transmission mechanisms, and frames and stringers are a system that determines the shape of the hull of a vessel and cannot serve for direct attachment of power mechanisms to them, in addition, the large presence of hinges of equal angular speeds determines the low reliability of the transmission in difficult x climatic conditions of the northern regions. The use of low-pressure tires, designed for maximum speeds of 50-80 km / h, limits the use in off-road conditions for long distances, and the propeller for a known craft as a propulsion system is ineffective, prone to winding algae and other objects. The all-terrain vehicle has a heavy displacement design with wheels, the transmission consists of metal-intensive units and mechanisms, which also leads to an increase in weight. The displacement of the engine and transmission from the longitudinal center of the structure leads to trim on one side, and the steering system does not provide a turn in place, which reduces maneuverability and poor control. A single-fuel engine limits the use, if necessary, of other fuel, and a two-section non-separable design limits the scope, i.e. and in the event of a serious emergency with the second section, it can lead to a decrease in the operational reliability and safety of people in the harsh northern climate.

The objective of the present invention is to provide a vehicle with increased operational reliability, high traffic when operating in off-road conditions on land and in water.

The technical result achieved in solving this problem is to expand the operational capabilities of the vehicle and improve maneuvering conditions by improving the layout of the chassis, the location of the wheel suspensions on traverses with lifting mechanisms for both their synchronous and separate control and on-board cornering.

The specified technical result is achieved by the fact that in an all-terrain vehicle containing a boat hull, an internal combustion engine, wheels, lever-spring suspension of wheels, a winch, a hydraulic drive of a vehicle propulsion device on the water, a driver's cab with a transport control system, a passenger compartment, doors in the rear of the passenger compartment, according to the invention, a power frame is placed inside the boat hull, on which there is a multi-fuel diesel engine with a hydraulic pump station, power units and a water cannon, outside the left and right sides of the boat mustaches are installed and fixed to the power frame front and rear mechanisms for radial lifting of the wheel blocks, driven by hydraulic motors for lowering and raising the wheel blocks, the left and right wheel blocks are identical structures consisting of bearing traverses pivotally mounted on the radial lifting mechanisms, while each traverse has four independent spring-hydraulic wheel suspensions, consisting of a system of levers parallel to the traverse, and on the base of the lower lever the case of a centrifugal hydraulic motor with a wheel hub is attached, while the power transmission of torque is carried out by hydraulic fluid through a piping system to the hydraulic motors of all wheels, to the hydraulic motor of the water jet, the hydraulic motors of the actuators, and the distribution, intensity and direction of flow of the hydraulic fluid to the hydraulic motors of the executive mechanisms is carried out by the system control with computer programming.

The centrifugal hydraulic motor contains a housing in which a ball bearing, a high pressure seal, a thrust washer are sequentially pressed, while a shaft is inserted into the ball bearing, which is a single design with a hub, and a turbine is pressed on the shaft splines on the opposite side of the housing, a cover is attached to the housing, in which is pressed into the high-pressure seal, a tapered bearing is pressed onto the shaft, which is pressed by the adjusting nut, and the housing has two threaded holes for mounting flexible high pressure hoses for the working fluid located on two opposite sides at a level above the axis of the shaft in the area of the working part of the turbine.

It is advisable that the hull of the boat was made of polypropylene.

The location of the wheel suspensions on the traverses having lifting mechanisms of both synchronous and separate control and on-board control of turns, allows to expand the operational capabilities of the vehicle and improve the conditions for maneuvering the all-terrain vehicle.

The lifting of the wheel blocks provides automatic transformation from a land vehicle into a planing boat, as well as the possibility of using rubber tracks if necessary, which ensures the highest degree of cross-country ability.

The all-terrain vehicle is made in the form of a hull 1 of a boat, for example, of polypropylene, made, for example, by molding, which provides increased resistance to deformation and damage to the bottom when in contact with solid objects. The housing 1 can be made of any other materials, for example, by welding. The hull 1 is the forming shell of the planing boat and does not carry other functions (Fig. 1-4).

In the front of the housing 1 is the driver’s cabin 2 (Fig. 1-4), in which the following controls and control devices (not shown) are convenient for the driver: pressure indicators in the hydraulic system (give readings only when the hydraulic station is running) : oil pressure gauge in the diesel engine lubrication system; liquid temperature gauge in the diesel engine cooling system; interior ventilation system switch; cabin light and taillight switches; cockpit light; ammeter; wiper switch; sound button; joystick, for example, type BDU-4 / 01.P hydraulic system; lever for turning on the water jet hydraulic motor; steering wheel (when turning in any direction until the latch clicks, it corresponds to the pressure gauge); handle of the central light switch and direction indicators; lever for manual control of the diesel engine fuel pump; control lamp for emergency coolant temperature, next to which there is a button for checking the status of control lamps for emergency coolant temperature and emergency oil pressure in the engine lubrication system; mountain and parking brake switch; pedal for controlling the fuel pump of the engine; brake pedal; control levers of the trailer hydraulic system; lever for activating the drive of the hydraulic pump station; warning lamp for emergency oil pressure in the engine lubrication system; clutch control lever; draft of control of the air damper for heating the passenger compartment; engine radiator shutter control handle.

In the driver's cab 2, there are also two joysticks of the positions of the wheel blocks containing the wheels 3 (the switching pattern of the joysticks is shown in Fig. 5). Each joystick when controlling the position of the wheel blocks can occupy the following positions: 0 - neutral position; 1 - synchronous lifting of wheel blocks; 2 - synchronous lowering of the wheel blocks; 3 - rise of the right wheel block; 4 - rise of the left wheel block.

Hydraulic system control devices and all-terrain vehicle controls located in the driver’s cab 2 are connected by high pressure pipelines to the power hydraulic pump station and power actuating hydraulic mechanisms. The hydraulic pump station is connected to the diesel engine through a clutch assembly and consists of three hydraulic pumps of various capacities. Various combinations of control of these pumps provides both high-speed modes and power transmission to the wheels. To heat the passenger compartment 4 and the driver's cab 2, the heat generated by the engine is used; at low temperatures, a fuel-gas heater is also used.

In the housing 1 is placed a bearing power welded frame 5, which is a three-dimensional structure (Fig. 6). Frame 5 consists of special pipes, for example thin-walled with an ellipsoidal profile made of carbon steel.

On the frame 5, in the middle or rear part, there is a diesel engine with a hydraulic power pump station, consisting of a carrying capacity of the working fluid, a block of control devices, regulating and control systems, three oil gear pumps of various capacities and a pneumohydraulic accumulator (not shown). The hydraulic pumping station is a power unit that ensures the operation of all actuators.

Inside the hull 1 on the power frame 5 in the aft of the boat there is a water cannon 6 (Fig. 1, 3), driven by a hydraulic motor (not shown). Outside the left and right sides, front and rear radial rotation (lifting) mechanisms (Fig. 2, 4), driven by hydraulic motors 7 (Fig. 6) of the drive mechanism for lifting the wheel blocks 8 (Fig. 2, 4), are mounted and fixed to the power frame )

The left and right wheel blocks are identical structures, consisting of bearing traverses 9, pivotally mounted on radial lifting mechanisms 8. Each traverse 9 has four independent spring-hydraulic wheel suspensions consisting of a system of levers parallel to the traverse 9, a spring, and a hydraulic shock absorber. On the basis of the lower lever is fixed to the body of a centrifugal hydraulic motor 10 having a wheel hub.

Independent suspension of the wheel (Fig. 7) contains a centrifugal hydraulic motor 10 of the wheel 3, wheel 3, the fixed lever 11, the attachment point 12 of the fixed lever 11 to the beam 9, the movable lever 13, a hydraulic spring shock absorber 14, kingpin 15, wheel disk 16, hydraulic motor 7 drive mechanism for lifting the wheel block, emphasis 17 of the upper fixed arm 11.

The centrifugal hydraulic motor 10 of the wheel 3 (Fig. 8) contains a base 18, a housing 19, in which a ball bearing 20, a high-pressure seal 21, a thrust washer 22 are successively pressed, while a shaft 23 is inserted into the ball bearing 20, which is a single design with the hub 24 On the opposite side of the housing 19, a turbine 25 is pressed onto the splines of the shaft 23. A cover 26 is fastened to the housing 19, into which the high pressure seal 21 is pressed, a tapered bearing 27 is pressed onto the shaft 23, which is pressed by the adjusting nut 28. The housing 19 has t Two threaded holes (not shown) for fixing the flexible high pressure hoses for hydraulic fluid, arranged on two opposite sides at a level above the axis of shaft 23 in a working zone of the turbine 25.

The hub 24 of each wheel 3 is a single structure with the shaft 23 of the centrifugal hydraulic motor 10, the housing 19 of which is connected to the base of the wheel suspension, as a result of which the wheel hydraulic motor 10 is located inside the wheel 3. This design of the wheel block provides each wheel 3 with an independent suspension and independent supply of working hydraulic fluid through a flexible high pressure hose.

The lifting mechanism of the wheel blocks (Fig. 6) contains a hydraulic motor 7, a pinion gear 29, a driven gear 30, an upper suspension bracket 31, a centrifugal hydraulic motor 10 of a wheel, a disk 16 of a wheel 3, a hub 24, a lower suspension bracket 32, a shock absorber 33, a traverse 9.

On the all-terrain vehicle, there are four mechanisms for radial lifting of wheel blocks located in the front and rear parts of the left and right sides, which are identical structures. A hydraulic motor 7 is installed on the inner side of the power bearing frame 5 and the boat hull 1, on the shaft of which, on the outer side of the bead, a pinion gear 29 is pressed in, which engages with the driven gear 30, which has its attachment to the power bearing frame 5. In a special thickening driven gear 30, an axis is pressed in, on which a traverse 9 is mounted on a sliding bearing, on which wheel suspensions are mounted.

Each wheel block by radial movement provides clearance in the lower position of up to 500 mm, and in the upper position of the wheel 3 are above the water level, which provides free gliding when moving on water, resulting in high speeds.

Wheel blocks can be raised and lowered, both synchronously and each independently of each other, in addition, they can change their position horizontally, which allows the driver of the vehicle to choose the optimal position of the wheel or caterpillar movers depending on the terrain and other factors the setting. The all-terrain vehicle has standard 15-inch car wheels with universal tubeless tires. The number of wheels is eight, the formula of the wheels is 8 × 8.

The all-terrain vehicle can be equipped with rubber tracks, which, if necessary, can easily be put on the raised wheels and pulled by the rear drive tensioners 34 and the front guide tensioners 35 (Fig. 1). An on-board turn allows the all-terrain vehicle to make a U-turn on the spot.

The hydraulic system provides reliable braking both to reduce speed and stop, and on slopes during a stop on an ascent or ascent.

All-terrain vehicle modifications can be represented by a wide range of models depending on the destination, for example, special for the Ministry of Emergencies, ambulance, resuscitation, passenger, postal, freight, etc.

The base vehicle is intended for: transportation of people and goods on impassable roads at speeds up to 120 km / h, on paved roads up to 150 km / h and on water at speeds up to 60 km / h. All-terrain vehicles are not an obstacle: swamps, light forests, climbs of up to 50 ° and slopes of 35 °, downhills of 55 °, obstacles up to 0.5 m high. The all-terrain vehicle has such capabilities, including due to the wide range of control of wheel blocks. The engine of the all-terrain vehicle is a multi-fuel diesel engine, which makes it possible to refuel it with any fuel. Power reserve of 600 km without reserve fuel.

The transformation of the all-terrain vehicle is carried out by the driver through the inclusion of appropriate programs that are most effective for the current conditions for the movement of the all-terrain vehicle.

The specifications given are for the base model. To ensure larger transportation tasks of the all-terrain vehicle with all the structural foundations preserved, all-terrain vehicles of large capacities, dimensions, capacity and carrying capacity can be produced. A multifunctional vehicle can be created on the basis of an all-terrain vehicle. Due to the presence of ball coupling with an automatic hydraulic connection unit, an additional transport section (second section) can be connected and disconnected automatically, with duplication of all functions of the first section, except for an engine with a hydraulic pump.

The transformation of the car provides the following functions: Salon 4 for transporting people (Figs. 1-3), with the seats removed it is used as a van, automatic removal of Salon 4 on a flyover turns the car into a truck, a dump truck, the ability to install attachments, as in the front of an all-terrain vehicle the special shape of the bucket on the retractable design of the U-shaped boom ensures self-loading of bulk cargoes; behind the driver's cab, a hinged type hydraulic crane can be folded S 250 kg.

The all-terrain vehicle can be equipped with other mounted hydraulic mechanisms, for example, the automated shift of the passenger compartment 4 turns it into a cargo dump truck, the presence of a transformable bucket provides the function of a light bulldozer and a forklift truck, the presence of a compact hydraulic crane (manipulator) ensures self-loading of loads up to 250 kg, easy removal of seats from passenger compartment turns it into a van.

Various modifications of the all-terrain vehicle are designed to transport people, various cargoes, to ensure constant transport communication at any time of the year when off-road, and can also be used for various special purposes, for example, in the Ministry of Emergencies, ambulance, for geological reconnaissance, in the development of hard-to-reach areas, for hunting, fishing and widespread use in the private sector. Various modifications of the all-terrain vehicle can be widely used in the armed forces.

All-terrain vehicle is used as follows.

The operation of the all-terrain vehicle is ensured by the governing bodies of various systems that carry out movement, turns, transformation of the all-terrain vehicle from a land vehicle to a water vehicle and vice versa, as well as the operation of all auxiliary and mounted mechanisms of the all-terrain vehicle.

Management of the base model of an all-terrain vehicle is not much different from modern vehicles with an automatic transmission system.

The kinematic model of hydraulic power transmission of torque provides a reliable easily-controlled possibility of multivariate combinations of choosing the necessary modes of power use when driving an all-terrain vehicle.

When the all-terrain vehicle is parked before the hydraulic pumping station is turned off, the brake lever is set to the “stop” position, while the hydraulic fluid supply valve and the selection valve are activated, while the pressure on the blades of the hydraulic motors of the wheels is simultaneously fixed by pressure from both sides, thereby ensuring reliable braking of all eight wheels of the all-terrain vehicle. During engine start-up and warm-up, the clutch is disengaged and the hydraulic pump station does not work.

During long-term parking or, if necessary, the all-terrain vehicle can be in the parking mode with the raised wheel blocks on the bottom of the boat hull.

After the engine has warmed up, the driver uses the clutch lever of the drive of the hydraulic pump station to connect it to the diesel engine, when it is working in the hydraulic system, working pressure is maintained, supported by pressure regulators and hydraulics, all levers and switches are in the neutral position. After setting the parking brake lever to the zero position, the entire hydraulic system is ready for further work.

The hydraulic pump station begins to work from the moment the clutch is turned on, and until the bypass valves receive a command to turn them off, the working fluid circulates through the internal system of the pump station. In a hydraulic pumping station, three gear pumps, which receive torque from a diesel engine through a clutch and a three-shaft gearbox, are the converting mechanism of mechanical energy to hydraulic. Various combinations of connecting and switching hydraulic fluid flows allow the most efficient use of the kinetic energy of the hydraulic pump station.

The presence of a high-pressure pneumatic accumulator (for example, a steel high-pressure cylinder is filled with compressed air from a diesel engine compressor, a cylinder is installed directly at the pump station, and its operation is controlled by the critical load automatic system of the power system) compensates for the possible lack of power during critical loads that may occur in extreme situations, for example, when climbing too steep uphill.

The hydraulic system has an automatic blocking of the flow of working fluid to the hydraulic motors in the event of an emergency, which makes it possible for the all-terrain vehicle to move even when several wheel hydraulic motors fail.

During the rotation of the steering wheel, the kinetic energy transmitted by the hydraulic fluid proportionally changes with respect to its effect on the turbines 25 of centrifugal hydraulic motors 10 of the wheels 3, i.e. when the steering wheel is turned to the left, large kinetic energy acts on the starboard hydromotors, and proportionally less on the left, which provides the all-terrain vehicle with maneuverability right up to a turn on the spot.

All-terrain vehicle clearance is from 0 to 500 mm, the clearance is changed due to the radial raising and lowering of the wheel blocks. Mechanisms for changing the position of wheel blocks driven by hydraulic motors can change their position both synchronously and independently.

Driving into the water, the driver lifts the wheel blocks, as a result of which the all-terrain vehicle is afloat, the hydro-motor of the jet 6 is turned on, and the all-terrain vehicle continues to move in planing mode.

If necessary, the all-terrain vehicle can be put on a caterpillar track. In case of such a need, the wheel blocks are lifted onto the wheels and rubber tracks are put on their tensioners, the driver turns on the track tensioner hydraulic motors, after tensioning the tracks, the driver joystick turns on the wheel block radial lowering motors, while the all-terrain vehicle, standing on the tracks, can continue to move. Track removal is performed in the reverse order.

The design of the basic model of an all-terrain vehicle is designed to carry passengers in the fixed-route taxi mode over long distances, usually off-road: the all-terrain vehicle has a comfortable all-terrain vehicle with permanent mounting on the chassis with fixed seats and seat belts.

The design of the cabin with the sides opening upwards provides a quick landing of passengers (lifeguards, an option for the Ministry of Emergencies).

Modifications of the all-terrain vehicle differ from the base model by the specifics of the designs of equipment installed on the chassis, for example, ambulance, emergency situations, etc., one of the options is with a movable cabin on a flyover (in this case, transformation into a light dump truck).

The on-board computer programs of the control system with computer programming as a result of processing control readings of the various systems of the entire mechanism determine the optimal working solutions for all vehicle systems and control the critical moments of their operation.

Some modifications of the all-terrain vehicle, for example, the Ministry of Emergencies, for hunting, fishing, etc., can be equipped with special searchlights.

The main technical characteristics of the all-terrain vehicle are as follows:

- car (all-terrain vehicle of unlimited cross-country ability) floating, wheeled, tracked - modifications passenger, cargo, specialized - scope of off-road of any category, water obstacles - wheel formula 8 × 8 + tracks - full mass 2.25 t

- capacity 10 people - carrying capacity up to 1.5 t - engine multi-fuel diesel - power 120 h.p. - turning radius 8 m control of all wheels - U-turn on-board - clearance 0 to 500 mm - maximum speed on the highway up to 160 km / h cross country up to 120 km / h afloat up to 70 km / h - power reserve without reserve 600 km - overcoming climb more 40 ° - movement on a slope 30 ° - overcoming obstacles to 0.5 m

When connecting the second section to the all-terrain vehicle, a coupling device (not shown) is used, which has high flexibility due to the presence of additional horizontal and vertical hinges.

The reliability of the hydraulic system of the second section is ensured by a special coupling of increased reliability.

Sufficient diesel engine power and high efficiency of the hydraulic energy transfer system to the executive hydraulic motors provide reliable all-terrain vehicle overcoming obstacles in any climatic conditions. The presence of the contours of a planing boat and a water cannon make it possible to achieve high speeds on water.

The all-terrain vehicle carries out a turn on the spot, provides the ability to control the lifting of the wheel traverses, both synchronously and separately for each, allows you to balance the center of gravity vector when overcoming slopes.
