Abstract

This invention can be used for transport vehicles to enhance tire traction.The suggested antiskid device (fig.1) ensures tire-road adhesion by means of two contours that enfold wheels (9). The links (1) of these contours are mutually fixed with flexible ties 2 and 3. The ties (2) are of certain fixed length and positioned on the opposite side of the wheel (9), while the tie (3) equipped with the tightening device (4, 5, 6) is on the outer side of the wheel. Each contour link can be fitted with supplementary connection straps (8) to enhance the road grip of the tire.The suggested device is safely attached to the wheel and is simple to make and maintain. It takes up little room when folded and put away.<IMAGE>

Description

VEHICLE WHEEL ANTI - SLIDING DEVICE

The invention can be applied to vehicles to increase the adhesion of wheel tires to the road surface.

I t

Known anti-slip device - USSR aut. From 1643194 adopted as a prototype. In this device, the ground grip contours are mounted on radially positioned sections of the housing and are designed as articulated link pieces. Access to the tread contours is ensured by a system of tensioning mechanisms, which consists of a series of articulated joints, which are covered by flexible ropes.

The known drawbacks of the device are its complexity, insufficient grip on the wheel treads on the tire tread, laborious installation and removal of the device on the wheel.

»

The purpose of the proposed solution is to simplify the installation and removal of the anti-slip device. This purpose is achieved by the formation of the ground grip contour as two connected, longitudinally extending sections which span the surface of the wheel and are interconnected by three flexible tensioners, two of which are fixed on opposite sides of the wheel and the third pulling mechanism. In order to increase the traction of the tires on the ground, each section may have a linkage adjacent to the wheel surface, connecting the longitudinal edges of the sections.

The anti-skid device consists of two interconnected sections (1) covering the surface of the wheel. They are made, for example, of a steel bar with a diameter of 10 -12 cm. The sections (1) are interconnected by two fixed-length clamps (2) and a third clamp (3), equipped, for example, with a screw-tightening mechanism consisting of a handle (4) with a screw (5) and a nut (6) ( possibly also a mechanism for tightening the bullet - not shown in the drawings). The sections (1) have loops (7) in which the flexible tensioners (2) and (3) (rope or chain) are hooked. The section (1) may also have a coupling (8) (in one embodiment) that fits on the wheel surface (9) with an axle (10) when the section is mounted on the wheel. If the coupling 8) is made up of two elements as shown in Fig. 4, in addition to welding with the section (1), they are also welded to each other at their connection point.

To overcome difficult roads, the device is mounted on the guide wheels of the vehicle in this manner.

The two sections (1) with the previously released clamps (3) are tightly fitted from top to bottom - on the wheel (9) so that there is one clamp (2) with a fixed length on the outside and a clamp (3) with a clamping mechanism. In this case, the shortest clamps (2), one on the outside of the wheel (9) (Fig. 2) and the other on the inside (Fig. 3), will be at the top of the wheel and the clamp (3) below the axle (10). By tightening the clamp (3) with the rotary handle (4), screw (5) and nut (6), the sections (1) are firmly fixed and fixed on the wheel (9), preventing the device from slipping on the wheel surface. To remove the device from the wheel, only the retaining mechanism of the clamping device (3) must be released by unscrewing the screw (5) from the nut (6) with the handle (4), flipping the sections (1) sideways and removing the device from the wheel. This can be easily done if the wheel (9) is in the position relative to the ground as shown in Fig. 2, i.e., if the wheel contact point with the ground is at the greatest distance between the sections (1).

If the device has optimum dimensions, it is possible that, when mounted on the wheel (9), the clamps (2) are within 2/3 of the wheel radius (10) and the clamp (3) is within 1/3 of the axle ( 10). By using the steps (1) as shown in Fig. 4, the number of ground adhesion points is increased compared to the variant of Fig. 1 and the device can be used for trucks. The device can be easily and quickly mounted (also removed) on the vehicle wheel and securely mounted on its surface. The device provides a good grip on the road surface and leaves little space when folded.
