Abstract

FIELD: transportation.

SUBSTANCE: vehicle flotation improvement device consists of grousers located along tire wheel tread surface. Each of grousers is made in form of bent bracket. Grooves acting as grousers are made on grouser surface in contact with road bed. Lateral surfaces of grousers have bends repeating bends of tire wheel side surfaces. On the external lateral surface of the grouser there is a mechanism for fastening the grouser, consisting of a pressure insert, in which there is a bolt fixed in the pressure insert with a spring ring. During bolt rotation, pressure liner moves, clamping device on wheel tire tread and locked by locking nut.

Description

The invention "Device for increasing the cross-country ability of the vehicle" relates to additional equipment and is intended to increase the cross-country ability of cars equipped with single-wheel and double-wheel wheels.

Numerous devices are known for eliminating wheel slippage, for example: traction chains, traction control devices called lugs, rubber chains, 4WD anti-skid bracelets, Tplus and Nordis. etc.

However, some of these devices are ineffective on the road covered with dirt or snow (spikes and their analogues), others are characterized by a small area of contact with the road, and therefore are ineffective. At the same time, many of the listed devices have a common drawback, the installation of these devices is impossible in situations of a car stop: on a slippery, icy and snowy road, on an ascent uphill, in holes, i.e. in those situations when traction control devices are absolutely necessary.

Closest to the claimed device for increasing the cross-country ability of the car is a device (see RF patent No. 2394694), (1) selected as a prototype, containing a chain, an arcuate strip with an eye, with two holes in which are inserted the studs with nuts, to which the chain is attached, while the arcuate bar is made with the possibility of fastening to the rim of the wheel with a stud.

The disadvantage of this device is the time-consuming installation, in addition, when installing this device requires drilling regular wheel rim.

The invention is illustrated by drawings.

In FIG. 1, 2, 3 shows a single-wheel wheel with a metal lug and a mechanism for securing it. In FIG. 4, 5, 6, a single-wheel wheel with three metal lugs and mechanisms for their fastening is shown. In FIG. 7, 8 shows a gable wheel with three metal lugs and mechanisms for their fastening. In FIG. 9, 10, 11, a single-wheel wheel with three grousers made of plastic with spikes (for example, polypropylene) and their fastening mechanisms is shown. In FIG. 12, 13 shows a gable wheel with three grousers made of plastic with spikes and mechanisms for their fastening.

A device for increasing the patency of the car consists (see Fig. 1 ... 13) of the lugs 1, the fastening mechanisms of the lugs 2, consisting of a liner 3, a spring ring 4 and a bolt 5 with a locking nut 6.

Grouser 1, made in the form of a bent bracket, has a bend on both sides, repeating the bending of the side surfaces of the wheel tire. A hole 7 is made on the surface of the lug 1 in contact with the roadbed, and along the edges of the ribs 8, this allowed to reduce the mass of the device, increase the grip of the wheel and the road, and increase the passability of the car.

The lug 1 is mounted on the tread of the wheel tire, and the attachment mechanism of the lug 2 is mounted on the outer side surface of the wheel, when the bolt 5 is rotated, the liner 3 is moved and pressed to the side surface of the wheel tire, thereby securing the lug 1 on the tread of the wheel tire. After fixing, the lug 1 is fixed with a lock nut 6.

Grouser 1, as well as mechanisms for securing the grouser 2, can be made of carbon steel, followed by galvanic coating, alloyed stainless steel, alloys with high abrasion resistance.

Grouser 1 (see Fig. 9 ... 13) can be made of plastic (for example, polypropylene), on the surface of the grouser 1 in contact with the roadway, ribs 8 and spikes 9 are made.

A device to increase the cross-country ability of the car as follows.

Option 1 (see Fig. 1, 2, 3).

If the car stops and cannot move further due to wheel slippage, for example in a pit or on a slippery and snowy road, the engine is muffled and the tire protector is mounted on the drive wheel, the lug 1 is installed, when the bolt 5 rotates, the liner 3 is pressed against the side surface of the tire wheels, securing the lug 1 on the tread of the tire wheels. Bolt 5 is locked with nut 6. The same is done with the second drive wheel.

Option 2 (see Fig. 4 ... 13).

Three drive lugs 1 are mounted on the driving wheels evenly around the tire tread perimeter, the installation of the lugs does not differ from the installation described in option 1.

With continuous operation of the car, depending on the complexity of the road conditions, the number of lugs mounted on wheels can be different, it is recommended to install from 3 to 7 lugs on one wheel, and their number on the right and left wheels of one axle should be the same and evenly distributed along the perimeter wheels. To achieve a relatively smooth uniform movement on off-road, loose and compacted snow, in most cases 7-8 grousers per wheel are sufficient.

To install "Devices for increasing the patency of the car" does not require raising the wheel of the car with a jack. The possibility of installing the lugs, in any quantity, is ensured by the fact that after installing one lug in any convenient place, the wheel is turned (by the engine) by a certain angle and the following lugs are installed in the same way.

During the operation of the “Device for increasing the cross-country ability of a car”, the fastening of the lugs may be loosened, in this case, the lock nut 6 is loosened, and when the bolt 5 is rotated, the lug is fixed to the tread of the wheel tire and locked with the nut 6.

The big advantage of this device is that it can be installed without problems in any situation, both on a single wheel and a double wheel, even if the car is stuck in the mud.

After passing a difficult section of the road, the device can also be easily removed by loosening the lock nut 6 and unscrewing the bolt 5, while the liner 3 moves away from the side surface of the tire and the lug loosens freely from the tread of the wheel tire.

Installation and removal of the dirt track 1 takes no more than 1-2 minutes.
