The invention relates to mechanical engineering and can be used in wheeled vehicles.

A device SU 292A.30.05.1925.

The disadvantage is the inconvenience of control.

The aim of the present invention is to eliminate this drawback.

The device consists of a collapsible casing in the form of a sector covering a particular sector of the wheel.

Management of the casing is carried out by means of the handle from the driver's cab through a system of levers by means of an adjustable gearing, in which the rear axle freely planted sleeve, rigidly connected with the said casing having a ring gear, at offset along which axis is its coupling with a ring gear rigidly mounted on the rim of the wheel for rotating the wheel casing, and in another position of the sleeve are available on one of its sides, the teeth engage with the teeth of the rear axle to secure the cover on top of the wheel.

Figure 1 shows a General view of the casing. On the rear axle 1 freely planted collapsible sleeve 2 having teeth 3 for engagement with the teeth 4 of the rear axle. The groove 5 for connection with the lever system 6 control from the cab handle 7. On the axis of the wheel freely setting sleeve 8, is rigidly connected with the casing 9, the second sector which is rigidly connected to the sleeve 2, with the teeth 10, 10 a and 3 for coupling with the teeth of the and 11, a ring gear 12 and the gear engages the rear axle 4.

Figure 2 shows a variant of fastening of a casing with two simple pins. Under POS shows the surface underfoot.

The control is performed as follows. When submitting the handle "forward" sleeve with cover moves along the axis and engages with the axle and wheel and unlinked with the rear axle in the casing rotates with the wheel. When the position of the handle back cover unlinked with the axle and the wheel and is now in gear engages the rear axle.

The advantage is that the device is easily controlled from the cab of the vehicle, which provides a higher throughput of vehicles.

Device for improving the patency of vehicles containing casing in the form of a sector covering the wheel, mounted rotatably around the axial line of the wheel, characterized in that the control casing is carried out by means of the handle from the driver's cab through a system of levers by means of an adjustable gearing, in which the rear axle freely planted sleeve, rigidly connected with the said casing having a ring gear, at offset along which axis is its coupling with a ring gear rigidly mounted on the rim of the wheel for rotating the wheel casing, and in another position the Institute bushings available on one of its sides, the teeth engage with the teeth of the rear axle to secure the cover on top of the wheel.
