Removable device to increase the patency of the car

 

(57) Abstract:

The device includes a chain bracelets. Each bracelet semicircle covers the tire of the wheel. Bracelets are evenly spaced on the wheel due to the equal length of the screed. One plate sliding. Each bracelet contains two base - connecting the nodes of the elements of the device. For each basis set two fungal castle. The technical result - the simplicity of construction, compactness and reliability of the device. 5 C.p. f-crystals, 3 ill.

Usage: in the operation of the vehicle to increase its cross-road, on muddy dirt road, in the snow, in the sand.

The inventive device includes five removable chain bracelets Fig. 1, evenly spaced on the wheel, and each bracelet includes a semicircle bus wheels on the inner side of the wheel bracelets are interconnected with five removable couplers Fig. 2 through fungal locks 1 Fig. 1, located on the grounds 2 Fig. 1, the presence of hard walls 3 of Fig. 1 on the basis of blocking the possibility of inadvertent disconnection of the device when it is installed on the wheel; the outer side of the wheel bracelets are interconnected by four tie-rods Fig. 2, the STS-skid [2] , [3] and [4] with one-sided mounting on the tire of the wheel. Such design incorporates one major drawback: during operation resulting shock load disturb the geometry of the brackets, covering bus, the design of the device cumbersome that it is not possible to constantly carry them in the trunk of a car.

In the patent literature there is a close analogue, which can be considered the prototype of the invention [1]. Its essential elements are chained bracelets are attached to two pairs of arcs and attached to the lid. As at the time of stopping the tension device on the wheel relaxes, then stops and reverses possible separation arcs. This device is also difficult to place in the trunk of a car as complete removable equipment.

The proposed device is removable all - terrain much easier the considered structures, dismantling of the element that allows to compactly stow in your pack and use constantly as a removable component equipment of the car.

The difference of the proposed device from existing analogues in connection node of the base of the bracelet 2 Fig. 1 and coupler of Fig. 2 or Fig. 3.

To connect bracelet with stablestate the axis of the hole in the coupler and lock the base of the bracelet, press the coupler to the base of the bracelet and the groove in the plate to move the plate to lock groove ties at the neck of the castle, to expand the coupler around the castle grounds bracelet, blocking the possibility of its removal. To turn the tie around the castle, it is necessary in the manufacture of couplers to combine the center of the circle groove couplers and diameter of the rounded end portion of a rod, the width of the screed.

During removal of the device after the pre-rotation coupler parallel to the thrust wall, installed on the base of the strap, as in other positions screed separation impossible to press the longitudinal side of the screed resistant to the wall, pressing the plate toward the base of the bracelet beveled stop 6 Fig. 2 on the plate 5 of Fig. 2 rests on the base of the bracelet, which leads to the rise of the screed above the base, as well as fungus castle, set on the basis of the bracelet and the hole on the coupler is made oblique, combination lock and holes on the coupler of the last disconnected with the bracelet.

Thus, in the proposed device solved the problem of release: i.e., ease of mounting and quick disassembly.

The purpose of the invention: simple design, the device is disassembled and the storage device as a removable component equipment of the car.

This goal is achieved by the fact that in the device chain bracelets 4 Fig. 1 is fixed on the base 2 of Fig. 1, the nodes connecting device.

On the basis of set: two fungal castle 1 Fig. 1 for mounting the unit, hard wall 3 of Fig. 1 to block spontaneous separation device when it is mounted on the wheel and the orientation of the coupler for combining the castle and the holes on the plate during removal.

The bracelet of Fig. 1 in a semi-circle covers the tire of the wheel.

Bracelets are evenly spaced on the wheel at the expense of the same length removable couplers Fig. 2, five on the inner wheel side, four on the outside, the fifth coupler sliding Fig. 3.

By sliding the plate 7 Fig. 3 welded nuts 8 Fig. 3 with a protective stockings for prevention of the thread sliding studs 9 Fig. 3.

The pin is selected of such length that it is possible to fix the device on the bus in different sizes for this type of car and permissible wear of the tread.

The use of the device five chain bracelets allows its installation on the wheel without lifting the wheels and additional maneuvers of the vehicle, ensures even distribution of pressure on the Tob with the ground.

Offered for bracelets chains kruglozerny trucks and traction GOST 2319-70, chain gauge depends on the traction force of the vehicle, the traction force depends the size of other elements of the device.

On the figures welding not shown in order not to obscure the relative positions of the parts.

1. Removable device to increase the patency of the car, including chain bracelets, each bracelet semicircle covers the tire of the wheel, bracelets evenly spaced on the wheel due to the equal lengths of the couplers, one coupler sliding, characterized in that each bracelet contains two base - connecting nodes of device elements, each basis set two fungal castle.

2. The device under item 1, characterized in that each base bracelet set resistant wall so arr is on p. 1, characterized in that each coupler has two oblique stop so that when pressed oblique emphasis screed at the base of the bracelet there is a force aimed at separation of the screed with a bracelet.

4. The device under item 1, characterized in that the fungal castle grounds bracelet, hard wall at the base of the bracelet and oblique emphasis on the screed is installed so that when pressed against a longitudinal side of the screed to the hard wall at the base of the bracelet and the promotion of ties to touch base with slanting emphasis on the coupler combining axes fungal castle and the holes on the plate.
