Wheeled vehicle anti-skid and anti-sinking caterpillar band

Abstract

A wheeled vehicle antiskid and anti-sinking caterpillar band comprises a roller frame body (1) which is used for placing wheels and is through up and down, at least four roller shafts (2) which transversely penetrate through assembling holes in the roller frame body, rollers which are installed on the roller shafts and located in the roller frame body, and an annular caterpillar band body (6) which wraps the roller frame body, the rollers and the wheels. At least two of the roller shafts are installed at the two ends of the upper portion of the roller frame body. At least two roller shafts aremounted at the lower part of the roller frame body and are positioned on the inner sides of the two roller shafts at the upper part. The rollers mounted on the upper roller shafts are caterpillar band corner rollers (5), and the rollers installed on the lower roller shafts are load-bearing positioning rollers (3). The outer side rims of the caterpillar band corner rollers protrude out of the roller frame body to support the annular caterpillar band, the load-bearing positioning rollers are located in the roller frame body, and the bottoms of the wheels penetrate through the roller frame bodyfrom the position between the two load-bearing positioning rollers and are pressed on the annular caterpillar band. The anti-skid and anti-sinking caterpillar band is good in anti-skid and anti-sinking effects, simple in structure, light and low in manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of tire antiskid devices. Background technique [0002] When the car is running on an ice-snow road or a muddy road, if no preventive measures are taken, the tires will easily slip and fall into the snow or mud, causing serious driving safety and difficulties. Existing solution has multiple, and the most common is to install automobile anti-skid chain on tire, and this measure is simple and easy, but anti-skid ability is not strong, and road surface and tire wear and tear are serious, and can not solve the problem that tire gets stuck in mud. The prior art also has slipper-type anti-skid crawlers, which have better anti-skid and anti-sinking functions, but this anti-skid crawler and automobile tires are two separate bodies. It is easy to be hanged off by external objects, so it is not suitable for driving in woods and muddy ground. In addition, in the prior art, triangular crawler tires are used to replace...

Problems solved by technology

[0002] When the car is driving on icy or muddy roads, if no preventive measures are taken, the tires will easily slip and fall into the snow or mud, causing serious driving safety and difficulties.

There are many existing solutions, the most common is to install automobile anti-skid chains on the tires. This measure is simple and easy to implement, but the anti-skid ability is not strong, the road surface and tires are severely worn, and it cannot solve the problem of tires getting stuck in mud.

The prior art also has slipper-type anti-skid crawlers, which have better anti-skid and anti-sinking functions, but this anti-skid crawler and automobile tires are two separate bodies. It is easy to be hanged off by external objects, not suitable for driving in woods and muddy ground

In addition, in the prior art, triangular crawler tires are used to replace the original tires of the vehicle. This kind of triangular crawler tires has good anti-slip and anti-sinking effect, but its structure is complicated, the cost is high, the volume and weight are large, and it is inconvenient to carry. Difficult to install, all the original tires must be dismantled when using, and only professionals can install and disassemble with special equipment

The Chinese patent CN208118877U applied by the applicant of the present invention discloses the anti-slip and anti-sink track of the wheeled vehicle and the wheeled tractor, which solves the problems of the aforementioned technology well, and has a good anti-slip and anti-sink effect, and its structure is relatively Simple, but in the face of modern people's demand for automobile anti-skid devices with simpler structure, lighter weight and lower price, further improvement is still needed
