The invention relates to transport, namely, devices for increasing the permeability of vehicles when driving on a slippery road, off-road conditions in bad weather conditions.

You know the anti-skid device for a wheel, temporarily attached thereto (U.S. Pat. Of the Russian Federation No. 2092328, IPC VS 27/40), consisting of a hollow rod of rectangular cross section, embedded in one another and rigidly attached to the hooks of the rods with hooks, spring and interconnected with the Cam, comprises a base in the form of two tubes with longitudinal grooves, bonded plate and the ends of the tubes attached slidably in the slots tips too from tubes, curved radius at the ends with the holes and can be rotated on their axes shoes, made of plates having radial protrusions and ribs, with one Shoe is spring-loaded in a compressed state of the wheel, the second freely movable in the longitudinal direction and interconnected hand drive.

The disadvantage of this device is the complexity of design and manufacture, the great weight of the structure and a small lifetime of used parts and components.

Known wheel with retractable hooks (U.S. Pat. Of the Russian Federation No. 2176602, IPC7WV 15/26), including retractable hooks attached to the faceplate installed on the drive wheels, the hooks are located n the periphery of the shroud, fixed rotatably on the rim by means of the clamping ring, and have holes for fasteners installed on prijemnom ring intended for fixing of hooks, while the terminals of the latches kinematically connected with the established in-cab control lever connected to the brake holder.

The disadvantage of this device is the complexity of design and manufacture.

Closest to the present invention is a wheel with retractable hooks that contains the hooks located on the periphery of the shroud installed on the wheel rim, some of which are curved and hinged to the faceplate installed on the drive wheels (German patent No. 1159295, CL 63d 22/02, 1963, taken as a prototype).

The disadvantage of this device is the fact that the nomination of hooks depth is not adjustable and held in extended condition occurs constantly in the process of movement of the tractor with hydraulics, which increases energy costs.

An object of the invention is to increase the patency of the vehicle in a fairly simple design assistive devices, his small force specific ground pressure in the works, the ease of fabrication, high reliability, ease of maintenance and operation.

Technical solution to the problem is to establish what trojstva controlled from the cab depth extension lug using pnevmostartery and to change depending on operating conditions.

This object is achieved in that the device is made in the form of additional alloy, raverdiago hollow wheel drum type when applying pneumatic pressure through the expansion internally located pneumatic camera on the shoulder of the hinge is attached at a point on the inner side of the outer periphery region of the shoulder wheel lever, a spring-loaded at the point 1/3 of the total length, retractable hooks on the inside of the wheel rim opposite the guide holes, is the radial extension of the latter by an amount proportional to the transmitted pressure. Wheel rim and the lugs with openings in which are inserted pins for fixing hooks. The Central part of the wheel-drum cover is closed.

1 shows an auxiliary wheel to increase the patency of the vehicle (in section), figure 2 - scheme of work lug and cut the rim of the auxiliary wheel in figure 3 - view of the auxiliary wheel on the side in the section.

The device comprises a wheel 1, is made of alloy material in the form of a hollow raverdiago wheel drum type, which consists of the pneumatic chamber 2, the protective metallized rubber ring 3, the outer pneumatic chamber 2 before the shoulder lever 4, the shoulder growling is 4 with hinge mounting 5 is fixed on the inner side of the outer periphery of the wheel 1, at a point 1/3 of the total length of the shoulder arm set return spring 6, the sliding lugs 7 are located opposite the guide holes 8 on the wheel rim 1 with holes 9 of the fixing retractable lug 7, the wheel 1 is fixed to the main drive wheels of the tractor 10 by means of structural holes 11 and bolts 12, the Central outer part of the wheel 1 is made technological cover 13, the wheel 1 is connected to the tractor cab using pneumotropica, which features pneumogram regulation and supply air pressure.

The device operates as follows.

When entering on a soft surface (on the field) through pneumogram located in the tractor cab, served the pressure in the pneumatic chamber 2, which when the extension affects the shoulder hinge is attached at a point on the inner side of the outer periphery region of the wheel 1 shoulder of the lever 4, the spring at a point 1/3 of the total length with the help of the return spring 6, the shoulder, the arm 4 is in turn radially pushes the retractable lug 7, the inside of the wheel rim 1, opposite the guide holes 8, at length, without allowing slippage to move and to carry out agricultural work. Retractable lugs 7 may be fixed by the stud into the hole 9 in order to make the system more elastic the tee.

When going on a road paved through pneumogram located in the tractor cab, reducing the pressure in the pneumatic chamber 2, which narrows the return spring 6, attached at a point 1/3 of the total length of the shoulder of the lever acts on the shoulder hinge is attached at a point on the inner side of the outer periphery region of the wheel 1 shoulder of the lever 4 and radially pushes the lug 7, the inside of the wheel rim 1, opposite the guide holes 8.

The use of the invention will increase the maneuverability of the vehicle to increase its traction properties when inhaled intensive work with significantly less slipping of the wheels, and regulation of penetration of the lugs will provide optimum movement, convenience and reliability.

Auxiliary wheel with retractable lug containing a wheel with retractable hooks, characterized in that the wheel is made in the form of a hollow raverdiago wheel drum type of alloy material, which is attached to the main wheel and contains a pin-jointed at points on the inner side of the outer periphery of the wheel shoulder arms, the spring at a point 1/3 of the total length, retractable hooks on the inside of the wheel rim opposite the guide holes, the pneumatic chamber located within the Central part of the drum and is connected by pneumoperitoneum with pneumogram, located in the vehicle cab, between the pneumatic chamber and the upper arm of the lever lugs installed protective rubberized metallic ring thickness not less than 1.5 cm, a width corresponding to the width of the drum wheel, wheel rim and the lugs with openings in which are inserted pins for fixing the hooks, the Central part of the wheel-drum cover is closed.
