FIELD OF THE INVENTION The invention relates to self-propelled land vehicles with hoisting-and-transport equipment mounted on them (winch, turntable, dump truck, etc.).

The purpose of the invention is to increase the patency of the vehicle,

Figure 1 shows a vehicle with an auxiliary (emergency) drive to the driven or driving wheels from the winch; on fig.2 - a variant of the device of the vehicle with auxiliary drive on the driven wheels from the rotary cargo platform; in Fig. 3 - a variant with an auxiliary drive to drive wheels from a rotary cargo platform; figure 4 is the same, a fragment of a plan view: figure 5 is a block diagram of a chassis with a winch under various design options and operating modes.

The vehicle contains (see Fig. 1) a self-propelled chassis 1 with wheels (in the examples presented, driving 2 and driven 3), an engine 4 and a main drive (transmission) 5 of wheel rotation 2. On the chassis 1 is installed hoisting-and-transport equipment (PTO) ) in the form of a winch 6 with a drum 7 (PTO moving body) and a drive 8 from a transmission 5. A cable 9 with a load-gripping element 10 is wound on the drum 7. On the outer sides of the disks of at least two wheels of the same name, - driven 3 or driving 2, - coaxio mounted coils 11 via detachable connections 12 (see figure 5). The drum 7 and the coil 11 are interconnected by a cable 9 or two parts connected by a detachable connection 13, in this case including a load gripping element 10 and a reciprocal part 14. In this case, the cable 9 or its part with the element 14 is wound on a coil 11 and can be stored in guide rollers 15 mounted on the chassis 1 (on its frame).

The variant in FIG. 2 is characterized by the presence of an autonomous (independent of engine 4 and transmission 5 (engine 16 VET, the implementation of the VET in the form of a cargo platform (dump body) 17, rotatable in a vertical plane by means of a hinge 18 and a power cylinder 19. Platform 17 is a rotary element of the PTO.

The embodiment of Figs. 3, 4 differs from the previous one by the coaxial arrangement of the rollers 15 on the outer sides of the wheel disks 3 and the connection of the ends of the cable 9, respectively, to the coil 11 of the wheel 2 and the movable part of the platform (body) 17.

Other device variants are possible within the scope of the claims.

The device operates as follows.

In case of insufficient coupling of the driving wheels 2 with the ground or failure of the transmission 5 or engine 4. (in the presence of engine 16), drive 8 is turned on. Powered PTO 6-7 (see Fig. 1.5) or 17 (see Fig. 2 -4)

0 t there is no cable 9, thereby rotating the coil 11 together with wheel 3 (see, Fig. 1, 2) or wheel 2 (see Fig. 1 with a dotted image of cable 9. Fig. 3-4). When realizing the clutch torque of said wheel

5 with the ground, the vehicle moves in a direction corresponding to the direction of winding of the cable 9 on the reel 11 (in this case, forward).

If there is no need for the described device, the PTO 6-7 or 17 are disconnected from the coils 11: the elements 10 are disconnected from the mating parts 14 (see Fig. 1) or directly from the coils 11 (see Fig. 1 with a dotted image of the cable 9 and Fig.2-4).

5 Thus, the increase in the cross-country ability of the vehicle is due to the temporary provision of the main or additional torque on the driven 3 or driving 2 (in case of failure of their main drive) wheels due to the onboard anti-theft vehicle ..

The greatest positive effect from the use of the invention is in carrying out. NII device as an option with a standalone

5 engine 16 PTO, with an auxiliary drive to the driven wheels 3 and the use of an additional drive load-gripping element 10, because the first sign, in combination with the main ones, allows increasing

0 total pulling force and carry out movement when the main engine 4 is idle; the second sign, in conjunction with the main ones, is to temporarily turn the vehicle into an all-wheel drive and provide self-pulling out with insufficient adhesion of the drive wheels to the ground; the third sign, in conjunction with the main ones, is to simplify the device, facilitate and accelerate the change of operating modes.

0 Formula and sampling.
