Description

A wheel-driven rubber track

technical field

The utility model relates to the technical field of crawlers, in particular to a wheel-driven rubber crawler.

Background technique

The vehicle driving system mainly has two forms: tires and crawlers. The tire is a circular elastic rubber product that is grounded and purely rolling. It is installed on the rim to form a wheel. It supports the body, buffers external impact, and realizes contact with the road surface and ensures The role of vehicle driving, and because of the long service life of the wheel, strong bearing capacity, and small frictional resistance, it is widely used in vehicles running on the road; the track is a ground-sliding endless chain belt, mainly through the driving wheel, road wheel, induction wheel, etc. Due to the large ground area of the track, the small ground specific pressure, good passability, and little damage to farmland and roads, it is widely used in off-road vehicles, such as excavators, bulldozers and other construction machinery, tanks, etc. , Armored vehicles and other military machinery are also commonly used in combine harvesters, tractors, farmland transfer vehicles and other agricultural machinery. Rigid crawlers are usually used for engineering machinery and military machinery, which have large mass, fast running speed and heavy load; rubber crawlers are often used for agricultural machinery due to their small total mass and low driving speed. However, in actual application, for driving Farmland transfer vehicles between farmland and farmers require not only high speed and maneuverability when driving on the road, but also good driving anti-skid performance in the field. At present, these vehicles usually use four-wheel drive or multi-wheel drive. Wheel drive, but even with multi-wheel drive, once the farmland transfer vehicle enters the relatively soft farmland, it is still particularly prone to slipping and vehicle trapping.

Above the driving surface of the groove, at the same time, there is an oblique angle between the side elevation of the wheel tooth groove, the driving surface of the wheel tooth groove and the wheel tooth of the driving wheel, which is not only beneficial to the meshing of the wheel tooth and the wheel tooth groove, but also conducive to the discharge of the track when the track is driven. Mud, water, etc. that enter the main body of the track.

In the utility model, the cross-section of the driving tooth is a trapezoidal structure.

In the utility model, the tooth grooves of the wheels are symmetrically distributed on the inner surface layer of the track main body.

In the utility model, the side elevation of the wheel cogging and the driving surface of the wheel cogging are arc-shaped structures, which are convenient for the driving wheels of the farmland transfer vehicle to rotate, so as to improve the driving efficiency of the crawler belt.

In the utility model, the inclined angle set between the side elevation of the wheel tooth groove, the driving surface of the wheel tooth groove and the wheel teeth of the driving wheel is 5°-30°.

In the utility model, the wheel drive belt is a porous foam rubber structure, which has strong compression and tensile properties, which is conducive to the smooth transition of the track in the ring, reduces the movement resistance moment, and prolongs the service life of the track.

Beneficial effects: in the utility model, the inner surface of the crawler main body is provided with wheel tooth grooves and wheel driving belts, which are used for the crawler main body to be set on the crawler vehicles, and the wheel tooth grooves and the driving teeth of the farmland transfer vehicle are set in a corresponding relationship. It is convenient for quick replacement in the center to meet the needs of various purposes; at the same time, the wheel driving belt is a porous foam rubber structure, which has strong compression and tensile properties, which is conducive to the smooth transition of the track at the ring, reducing the movement resistance moment and extending the service life of the track.
