Description

A wheel-driven rubber track

technical field

The invention 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.

The technical problem solved by the present invention adopts following technical scheme to realize:

A wheel-driven rubber crawler, including a crawler body, wherein a steel wire layer for strengthening the stiffness of the crawler body is arranged in the crawler body, and the steel wire layer makes the crawler body not have compression and tensile properties, and prevents deformation and fracture of the crawler body at the same time , to improve the service life of the crawler main body; and drive teeth are provided on the outer layer of the crawler main body, while the inner surface of the crawler main body is provided with wheel cogging and wheel drive belts, which are used for the main body of the crawler to be set on the crawler vehicle, and the cogging of the wheel is in line with the farmland The driving teeth of the transfer vehicle are set in a corresponding relationship, which is convenient for quick replacement; in addition, the wheel driving belt is a porous foam rubber structure, and the wheel cogging includes the side elevation of the wheel cogging and the driving surface of the wheel cogging, and the driving wheel is installed on the wheel tooth. 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 present invention, the cross section of the drive tooth is a trapezoidal structure.

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

In the present invention, the side elevation of the wheel cogging and the driving surface of the wheel cogging are arc-shaped structures, which facilitate the rotation of the driving wheels of the farmland transfer vehicle and improve the driving efficiency of the crawler belt.

In the present invention, the oblique angle provided 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 present invention, 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, reduces the movement resistance moment, and prolongs the service life of the track.

Beneficial effects: in the present invention, 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 vehicle, and the wheel tooth grooves and the drive teeth of the farmland transfer vehicle are arranged in a corresponding relationship. It is easy to replace quickly to meet the needs of multiple purposes; at the same time, 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 at the ring, reducing the movement resistance moment and extending the track service life.
