The invention relates to the agricultural industry, in particular for vehicles intended for transportation. Known vehicle (A.S. USSR №927618, B62D 53/00), containing two-axle chassis with wheels, comprising a frame on which is mounted a motor-gear unit, cabin, remote control, and a platform pivotally connected to the chassis and located underneath the cylinder with lever system. The disadvantage of this device is that it lacks a mechanism for lowering and lifting the platform from the ground, due to the reduction of the list of types of freight and increase the complexity of handling operations that are performed during operation.

The closest to the proposed invention is a technical solution (prototype) is the vehicle by A.S. USSR №1142322, WR 1/02. It is a device that contains two-axle chassis with wheels and a frame in the form of two rigidly interconnected side members, which is equipped with an engine-transmission unit, cabin with remote control and swivel arm platform, equipped with a hydraulic cylinder and a mechanism for lifting and lowering. The disadvantage of this vehicle is also no mechanism for lowering the platform to the ground, making it difficult operation due to the high labor input handling, and when you need such as transportation, for example, farm animals, makes it impossible to perform them without any additional devices.

The basis of the invention is the task of expansion during operation of the sphere of use of vehicles in the national economy and reduce the complexity of handling during transportation.

To achieve the technical result of the hinged levers platform of the vehicle installed with the possibility of rotation around their common axis, which is hinged at the base, welded to the side members of the rear semi-frames with the possibility of overturning of the platform around the specified common axis. Thus, the mechanism of lifting and lowering the platform represents fixedly mounted on said General axis of brackets pivotally connected to the rods of the two cylinders of the hydraulic mechanism for raising and lowering the platform associated with the remote control, in this case each of the hydraulic cylinders mounted on the rear section and to the edges of the common axis rigidly attached two rope with the axes of the rear wheels. These distinctive features allow the platform stated the vehicle not only to fall and rise, but its edge to lie on the ground, i.e. nahodatsa is a causal relationship to achieve the stated technical result.

The claimed technical solution is illustrated by drawings:

figure 1 shows a General view of the vehicle;

figure 2 is a top view of the vehicle depicted in figure 1 (without platform);

figure 3 is a view As in figure 2;

figs.4 - made item B in figure 1.

The vehicle contains two-axle chassis with the front 1 and rear 2 wheels and the frame, which consists of front and rear semiframes interconnected by means of two hydraulic cylinders 3 and the rotating hinge 4, the front end of which is rigidly attached to the two front spar 5 front semi-frames, and to the rear two spar 6 rear semi-frames. On the front floor frame is fitted with cabin 7 with remote control and engine-transmission unit 8 with the engine and transmission, a body which by means of two sleeves connected to the onboard drives and driving the front wheels. The remote control contains a single hydraulic system, the valve with two handles 9 for tilting, raising and lowering the rear portion of the platform 10, and the control lever 11 to secure the platform in the transport position.

The platform 10 is placed on the rear section with two rigidly interconnected side members 6. Moreover, the platform is mounted on the pivot levers 12, which are installed with the possibility of rotation around their common about the and 13, hinged at the base 14, which is welded to the side members 6 and tilt platform around the specified common axis. Under the platform 10 is rigidly associated with it a frame 15, which rests on the rails 6. With the help of hydraulic cylinder 16 platform with sub-frame may be removed around the axis 13.

In addition, the platform 10 is equipped with a mechanism for lifting and lowering her to the ground and lock in transport position. The mechanism is designed in such a way. On the common axis 13 is rigidly mounted brackets 17, pivotally connected with two rods connected with the control cylinders 18 of the hydraulic mechanism for raising and lowering the platform, each of which is fastened his body to the cross-bar 19 of the rear semi-frames. To the edges of the common axis 13 is rigidly attached two yoke 20 with the axes 21, on which are mounted the rear wheels 2.

The control lever 11 by the fixing platform 10 is attached to the axis 22. The axis 22 is installed on the key (not shown) to the pulley 23. The pulley 23 is attached one end of a cable 24 (figure 4). The axis 22 of the control lever 11 is attached to the bottom of the cab 7 can be rotated in two brackets 25 with the slots 26. The latch 27, which engages with the grooves 26, with the button 28 and rod 29 secures the lever 11 in the "transport" and "lowering-lifting" (figure 4). The other end of the cable 24, which is attached to W is willow 23, connected to the pulley 30, which is located on the rear section. The pulley 30 by means of two rods 31 connected with the right and left locking devices. Each of the fixing devices are made in the form of a stop 32 mounted on the axis 33 can be rotated in the base 34, attached to the side member 6. The lugs 32 by means of springs 35 is permanently installed perpendicular to the side members 6 in position "fixed" and hinder the movement of the rails in the direction of their descent. This position stops responding "transport" position of the platform 10 and lever 11. The position of the stops 32 "raspikirovki" responsible position "lowering-lifting" of the control lever 11 (shown in figure 2 by the dotted line) and does not interfere with the movement of the rope 20 relative to the side members 6 when lowering the platform 10 to the ground because the lugs are pressed against the rails.

The control of the hydraulic system is hydrographically crane, which contains two arm 9 with the provisions of the "ascent", "neutral" and "floating". One arm 9 controls the hydraulic cylinder 16 for tipping, and the other by the cylinders 18 and lowering the lifting platform 10. Hydrographically faucet is connected by piping with pump and tank (not shown)and the hydraulic cylinders 16 and 18, forming a single hydraulic system.

Depending on the direction the movement of the cylinders 18 of the rear edge of the frame of the vehicle when lifting-lowering and tilting on the platform 10 can occupy three positions, turning in a vertical direction relative to the transverse axis of the front wheels:

- top, when the cylinders are fully extended and the rear portion of the platform is at some angle to the horizon, which corresponds to position the lifting arm 9 and the position of the "lower-rise" of the control lever 11 (figure 4 shown dotted);

lower, when the cylinders are fully engaged and the rear portion of the platform 10 is lowered to the ground, which corresponds to the position of the floating lever 9 and the position of the lowering-lifting" of the control lever 11 (figure 4 are shown by the dotted line). In this case the angle between on the ground platform and the horizontal axis of the rear wheels is equal to the angle of rotation of the vertical axis of the cab and horizontal axes of the PowerPack unit relative to, respectively, the vertical and horizontal axes of the front wheels;

- secondary (horizontal), fixed stops 32 and corresponds to the position of the floating lever 9 and the position of the "transport" of the control lever 11 (figure 4 shows the main lines).

The vehicle operates as follows. When you commit to the platform 10 in the transport (horizontal) position of the arm 9 gidroraspredeliteli crane are in a "floating" position, the control lever 11 is in the "transport" position (see figure 4), and the lugs 32 of the springs is mi 35 is rotated in position "fixed", i.e. are perpendicular to the rails, preventing the movement of the rope 20 around the axis of the rear wheels 2 and lowering the rear edge of the frame with the platform 10.

If necessary, the loading (or unloading) of the vehicle should the platform 10 to be lowered to the ground. For this purpose, the handle 9, which controls the hydraulic cylinders 18, switch on the supply of oil to the cylinders (position "up"). As a result, the cylinders 18 a few POPs, turning the rope 20 around the axis of the rear wheels and picking up on some angle from the horizon platform 10 with the sub-frame 15, release the lugs 32, which fix the position of the platform. Next you need by clicking on the button 28, move the control lever 11 to the position "lowering-lifting" (see figure 4), affecting thus, by means of the cable 24, the pulley 30 and rod 31 on the lugs 32, returning them in raspikirovki" (stops clamped to the rails). After that, the handle 9 of the valve that controls the hydraulic cylinders 18, transferred to the "floating" position, causing the rear edge of the platform, moving under their own weight horns 20 around the axis of the rear wheels and the common axis 13, is lowered to the ground. With all the vehicle frame is rotated in the vertical direction around the axis of the front wheels. This position of the platform with the least difficult is AMI manual labor to carry out the loading (unloading) of the vehicle.

After loading the vehicle the handle 9, which controls the hydraulic cylinders 18 are set to the position "up", a lifting platform 10 with the load in position slightly above horizontal, then fix it, put the handle 9 in the "neutral" position. Further, by setting the lever 11 in the "transport" position, the handle 9 is transferred from the "neutral" position in "floating". After that, the platform 10 under its own weight is lowered until it touches the two clips 20 lugs 32, settles in the horizontal (transport) position. The vehicle is ready for shipping.

Unloading of the vehicle is performed in the order specified above for the case of loading (unloading) of the vehicle with the lowering of the rear part of the platform to the ground.

If it was delivered, for example, bulk material (sand, grain, etc), his obligation is carried out by tilting the platform 10 without lowering her to the ground. For this purpose, the handle 9 of the control cylinder 16 is transferred from the "floating" position "up", after which the rod of the hydraulic cylinder 16 is retracted tilting the platform 10 with the load around a common axis 13. Upon reaching the platform, in the process of raising, a position at an angle to the horizon, cargo slides under its own weight on the bottom platform. Further transport is the main means move forward in low gear when the handle 9 of the control cylinder 16 is switched to the "floating" position. Exempt from the cargo platform 10 under its own weight, turning around the axis 13 on the lever 12 moves the piston rod of the hydraulic cylinder 16 into the cylinder and is lowered until it touches your frame 15 with the side members 6.

Pivot levers platforms are installed with the possibility of rotation around their common axis, which is hinged at the base, welded to the side members of the rear semi-frames with the possibility of overturning of the platform around the specified common axis. Thus, the mechanism of lifting and lowering the platform represents fixedly mounted on said General axis of brackets pivotally connected to the rods of the two cylinders of the hydraulic mechanism for raising and lowering the platform associated with the remote control. The case of each of the hydraulic cylinders mounted on the rear section and to the edges of the common axis rigidly attached two rope with the axes of the rear wheels, and raising and lowering the platform to the ground is performed by turning of the vehicle in the vertical direction around the transverse axis of the front wheels. In this case the angle between the lowered platform and the horizontal axis of the rear wheels is equal to the rotation angle of the vertical axis of the cab and horizontal axes of the PowerPack unit relative, relevant to the military, the vertical and horizontal axes of the front wheels (i.e. α=α'). Using the vehicles of this design expands the scope of their use and reduces the complexity of handling operations in connection with the possibility of loading directly from the ground without additional lifting equipment.

At the Kharkov tractor plant design study the possibility of creating a vehicle of this design.

The vehicle containing two-axle chassis with front and rear wheels and a frame consisting of front semi-frames where you installed the PowerPack and cabin with remote control and rear semi-frames, which are installed on an articulated arm platform, equipped with a hydraulic cylinder and the mechanism of its lifting and lowering, characterized in that the said pivot levers are installed with the possibility of rotation around their common axis, hinged at the base, welded to the side members of the rear semi-frames and tilt platform around the specified common axis, and the mechanism for lifting and lowering of the platform is a tough mounted on said General axis of brackets pivotally connected to the rods of the two cylinders of the hydraulic mechanism for raising and lowering the platform is RMI, associated with the remote control, in this case each of the hydraulic cylinders mounted on the rear section and to the edges of the common axis rigidly attached two rope with the axes of the rear wheels, while lowering and lifting the platform is carried out with the rotation of the vehicle around the axis of the front wheels in a vertical direction, and the angle between on the ground platform and the horizontal axis of the rear wheels is equal to the angle of rotation of the vertical axis of the cab and horizontal axes of the PowerPack unit relative to, respectively, the vertical and horizontal axes of the front wheels.
