Sliding and tipping preventing vehicle wheel

Abstract

The invention belongs to the field of agricultural machinery and particularly relates to a sliding and tipping preventing vehicle wheel. The vehicle wheel comprises a tyre, a vehicle wheel hub (2) and a sliding and tipping preventing device; the vehicle wheel hub (2) is provided with a boss protruding out of the outer side of the tyre, and the outer diameter of the boss is smaller than the inner diameter of the tyre; and the sliding and tipping preventing device comprises a hydraulic oil cylinder (1), a supporting circular ring (4), connection rods (5), soil entry rods (6) and a transverse connection rod (8). According to the sliding and tipping preventing vehicle wheel, the magnitude of the sliding and tipping preventing force can be adjusted at any moment according to the actual farm working condition, when sliding and tipping need to be prevented, the soil entry rods are stretched out to work, when sliding and tipping does not need to be prevented, the soil entry rods are drawn back, and additional resistance is avoided; the structure is simple, assembling and disassembling are both very convenient, the manufacturing cost is low, and maintaining is convenient; and the sliding and tipping preventing device is installed on the outer side of the tyre, a working area has no intersection with the tyre, so that the tyre is not damaged.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and relates to an agricultural machinery wheel, in particular to an anti-skid and anti-tilt wheel. Background technique [0002] In the process of agricultural operations, due to the influence of ground factors, dangerous situations such as agricultural machinery slipping, rollover, forward tilting, and backward tilting often occur, which poses a greater threat to the personal safety of operators and also affects the quality of operation and agricultural machinery. service life. There are multiple tire anti-skid devices on the market, mainly containing anti-skid chains, anti-skid belts, anti-skid claws, anti-skid teeth, automatic retractable blade wheels, anti-skid nails and the like. Anti-skid chains are the most commonly used and are generally made of iron chains, tendon chains or rubber chains. Its working principle is to concentrate the gravity of the vehicle on several points of the a...

AI Technical Summary

Problems solved by technology

This kind of scheme mainly has the following disadvantages: compared with anti-skid chains, it is bulky and inconvenient to carry with the vehicle; manual installation is required, which is inconvenient to install; fastening bolts need to carry a large load, which limits the service life of the device

These kinds of anti-skid devices generally have problems such as short service life, loud noise, inconvenient installation, and worn tires.
