Description

A multifunctional vehicle refers to vehicles and can be used in difficult terrain, in mines for transporting goods or storage facilities.

A universal tracked chassis on a single platform is known (see patent RU 2433934 C2, publication date 01/20/2011), containing a thin-armored hull with three compartments. The traffic control department contains traffic controls, instrumentation, instruments and main armament units, surveillance devices and three seats in the front of the compartment for the driver, commander and operator, cabinets of the main armament units and one seat for the operator in the rear branches. The middle compartment with the equipment of the main weapons. Sealed engine and transmission compartment located in the rear of the chassis. The engine-transmission compartment contains a mid-flight engine with a high-speed output shaft, a mechanical transmission, two final drives, a cooling system, a drive for backup generators, a gas turbine engine with traction generators. The undercarriage includes a caterpillar mover, hydraulic shock absorbers, a suspension mechanism, and a track tension mechanism. In the housing between the middle compartment and the engine-transmission compartment, an additional intermediate compartment is formed to the width of the entire chassis with a gearbox for backup generators and internal fuel tanks. Marching internal combustion engine is perpendicular to the longitudinal axis of the chassis. A high-speed output shaft is kinematically connected to an input gearbox having an additional power take-off shaft passing through the transverse motor baffle to the intermediate compartment for connecting backup generators. The fuel system is composed of internal and external tanks according to the scheme of sequential production of fuel. Unification of the tracked chassis on a single platform is achieved. The disadvantage of the design of the well-known multifunctional vehicle is the large mass and high cost of production.

The disadvantage of the design of the known caterpillar conveyor is the large mass and the swivel mechanism, leading to the destruction of the fertile soil layer when used in agricultural work and asphalt pavement when moving in urban conditions.

A known design of a caterpillar tractor (see patent RU 2385249 C1, publication date 03/27/2010), comprising an engine, a transmission with mechanical and hydraulic drives for the rotation and braking mechanisms of the right and left tracks via final drives, and also a steering wheel that is kinematically connected via a power steering with a link-regulator of the working volume of a reversible axial-plunger pump, the drive shaft of which is kinematically connected with the transmission, and the pump is connected by oil pipes with a reversing motor, the shaft of which connected to the caterpillar rotation mechanism, characterized in that the steering wheel is connected to the steering axle of the reversible axial plunger pump by means of the power steering and the linearity stabilizer so that the position of the steering wheel corresponding to the linear motion of the caterpillar tractor corresponds to zero pump displacement, moreover, the shaft of the reversible hydraulic motor is kinematically connected with two coaxial sun gears of planetary gears with the possibility of rotate them in opposite directions at the same time, while each sun gear through the satellites of the carrier, separate for each sun gear, is kinematically connected also with a common epicycle rigidly connected to the driven gear of the main gear of the mechanical drive, and the shaft of each carrier is connected through the final drive final drive gear with a drive sprocket of a track, the braking control mechanism of which contains a sensor for switching on and off the differential connection between the tracks. The disadvantage of the invention is the complexity of the manufacture of the structure.

The construction of a tracked vehicle is known (see patent RU 2305045C1, publication date 08/27/2007), consisting of a housing with independent rotation drives of motor sprockets and levers and tracked carts connected inside the housing, rotatably relative to the housing around axes aligned with axes of rotation of motor sprockets meshed with a caterpillar bypass, characterized in that the caterpillar carts consist of levers attached to the vehicle body with the possibility of swinging In the case around the axes, combined with the rotation axles of the motor sprockets, between the ends of the levers not connected to the motor sprocket, an axis is fixed parallel to the axis of rotation of the motor sprockets, on which a connecting rod is mounted for swinging, the cheeks are pivotally attached to the arms nearest to a roller is mounted rotatably to the side surface of one of the cheeks, wheels are fixed to the end of the levers, connecting rod and cheeks, and the rails are located on the side surfaces of the vehicle of the roller, in the middle part of the connecting rod, the ends of the rods are fixed with the possibility of rotation, the opposite ends of which are fixed on the cheeks with the possibility of free movement within the groove of the cheeks, the swing axis of the connecting rod, cheeks, the rotation of the roller, wheels and rods are parallel to the axes of rotation of the motor stars. The drawback of the design is the possible problems when using a trailer: the towing mechanism in turns can touch the tracks.

The objective of the invention is to facilitate excavation and handling operations, namely:

- development of the design of the vehicle, which remains stable on soils with a weak bearing surface, as well as providing high traffic and excellent maneuverability.

The technical result achieved by the invention is to implement the following technical solutions:

- a trolley with a rotary hydraulic cylinder;

- suspension of a multifunctional chassis;

- caterpillar mover.

To achieve the technical result, the following design of a multifunctional vehicle is proposed. The design of the chassis of the vehicle (Fig. 1) consists of an engine 1, a cab 2 (Fig. 2), a caterpillar mover 3 (Fig. 2), a trolley 4 (Fig. 3), a platform 5 (Fig. 2) that protects against deep immersion in the ground.

The torque from the engine 1 is transmitted through the transmission to the drive shaft 6 (Fig. 4), which drives the drive wheel 7, which is connected via a track 8 to the driven wheel 9, so the multifunction chassis is driven. The drive 7 and the driven wheel 9 are connected using the tracks 8 (Fig. 5) and traction 10 (Fig. 6). The shock absorber 11 (Fig. 7) is fixed at one end to the drive wheel 7, and at the other with a link 10, thereby damping vibrations that occur when the multifunction chassis is moving. To the drive wheel, the rod 10 is attached using the earring 12 (Fig. 7).

The design of the driven wheel is shown in FIG. 8 and FIG. 9. Using the flanges 13 (Fig. 8), the wheel bearing 14 is fixed and protected from dirt (Fig. 9).

The shaft of the driven wheel 15 (Fig. 10) by means of bearings 14 is fixed in the hub 16, but allows the wheel 9 to rotate freely.

Using bolts 17 and nuts 18, the hub of the wheel rim 19 (FIG. 11) is attached to the hub 16, and the tire 20 is put on the rim (FIG. 13).

Flanges 21 with bolts 22 (Fig. 12) are attached to the hub of the drive wheel 23, and also fix the bearings 24 from axial movement (Fig. 13).

Two bearings 24 are installed in the housing of the hub of the driving wheel 23 (Fig. 14). The drive shaft 25 on the thrust bearings 24 (Fig. 15) is located in the housing of the lever 26.

The shock absorber 27 (Fig. 16) by means of a bolted connection 28 is attached to the bracket 29, which is welded to the trolley 4.

The design of a multifunctional vehicle uses a torsion independent suspension, which allows you to more dynamically respond to uneven road surfaces and is more stable in turns.

The shaft 30 through a spline connection, the flange 31 and the guide sleeve 32 (Fig. 17) interacts with the torsion 33 and the suspension arm 26. When moving one of the caterpillar propellers in a vertical plane, the torsion bends and tends to return the propeller to its original position (Fig. 18).

The cart of the multifunctional chassis 4 consists of two half-frames 34 and 35, which are pivotally connected to each other. The rotation is carried out using the hydraulic cylinder 36 (Fig. 19).

The hydraulic cylinder 36 is secured by bolting to the brackets 37 welded to the trolley 4 (Fig. 20).

The proposed chassis design allows it to be used with the following attachments: with a body (Fig. 21), with a tipper body (Fig. 22), a chassis with a body and a loading bucket (Fig. 23), with a fork (Fig. 24), a crane-manipulator (Fig. 25), with a concrete mixer (Fig. 26), with an electric generator (Fig. 27), with a submersible pump (Fig. 28), with a hoist (Fig. 29), with a manipulator (Fig. 30).
