RU2607009C2 - Anti-skid for vehicle wheels - Google Patents

Abstract

FIELD: transport; machine building.

SUBSTANCE: invention relates to transport engineering, particularly large vehicles with drive rear wheels. Anti-skid consists of disc and rim. Rim is made of separate parts with rigidly fixed pins, installed on periphery of disc with possibility of radial movement and spring-loaded relative to disc by rigid springs working in compression. Anti-skid is detachable to be secured between drive rear dual wheels by means of fasteners of wheels.

EFFECT: effective anti-skid of wheels on icy and snowy road with minimum damage of asphalt road coating.

Description

The invention relates to transport equipment and is intended for vehicles with leading rear dual wheels.

Known anti-skid for passenger car wheels, made in the form of spikes rigidly fixed to the tire cover.

Their disadvantages:

the need to replace studded winter tires with winter tires, damage to studs on asphalt and concrete roads and the unsuitability of mounting studs on the tire cover for heavy vehicles, as possible lateral displacement of the spikes followed by falling out of the tire.

The aim of the invention is to provide an anti-skid for vehicle wheels, devoid of the above disadvantages.

The specified goal is achieved by the following constructive solution.

Antiskid for wheels of vehicles, hereinafter briefly: antiskid contains a disk with movably mounted spring-loaded parts of the rim with spikes. The anti-slip disk is made with holes for fastening, slots for fasteners of the rim and springs. The rim consists of separate parts on which the spikes are rigidly fixed, fixed along the edges of the disk.

The invention is illustrated by drawings.

In FIG. 1 shows a non-slip disk, side view, with fasteners and springs, cross section; in FIG. 2 - a disk with a rim fixed on it; in FIG. 3 - rim, cross section, in FIG. 4 - view from above, from the outside; in FIG. 5 - anti-slip assembly, side view, outside.

The disk 1 (Fig. 1) of the anti-skid is made with a hole 2 for attaching to the wheels. In the longitudinal slots 3, fasteners 4 of the rim 5 (Fig. 2) and a rigid compression spring 6 (Fig. 1) are installed. The rim 5 (Fig. 2, 3) consists of separate parts fixed to the disk by pins 7 with flared ends located in flush holes made flush with the side surfaces of the rim. All parts of the rim are made with a cavity 8 (Fig. 3) for the springs 6. On the rim 5 (Fig. 4) the studs are rigidly staggered staggered 9. The optimal length, cross-section of the studs, the distance over which the parts of the rim with the studs extend are determined by the calculated or experimentally.

The springs are made with stiffness, which provides effective anti-skid wheels on an icy and snowy road with minimal damage to harder asphalt and concrete roads compared to ice and snow. The necessary degree of spring stiffness is also determined by calculation or experimentally.

The anti-skid is installed between the paired rear drive wheels and is fixed with fasteners, with which the two wheels are connected together.

Antiskid for wheels of vehicles works as follows.

When driving in icy conditions on snowy roads, anti-skid spikes prevent the wheels from slipping and, thanks to the presence of springs, reduce damage to asphalt and concrete roads. When traveling long distances, it is advisable to carry a pair of anti-skid vehicles in vehicles, fixing them on the side surfaces of the spare wheel.

Claims (1)

Anti-skid for vehicle wheels, containing spikes, characterized in that it consists of a disk and a rim made of separate parts with rigidly mounted spikes mounted on the edges of the disk with the possibility of radial movement and spring-loaded relative to the disk with hard, compressive springs, the anti-skid is removable between the driving rear dual wheels using wheel fasteners.
