Description

Tensioning wheel assembly of crawler tractor

Technical Field

The utility model relates to an agricultural machinery technical field particularly, relates to a track tractor's take-up pulley assembly.

Background

Unlike a wheeled tractor, a track is supported on the ground by a coiled endless track. The caterpillar belt contacts the ground, the caterpillar spike is inserted into the soil, and the driver is not grounded. The driving wheel continuously rolls up the crawler from the rear under the action of driving torque through the engagement between the gear teeth on the driving wheel and the track shoe joint pin. The ground engaging portion of the track imparts a rearward force to the ground and correspondingly imparts a forward reaction force Pk to the track, which Pk reacts the driving force urging the tractor forward. The driving force of the wheeled tractor is directly transmitted to the walking wheels, while the driving force Pk of the crawler tractor is transmitted to the wheel axle of the driving wheels through the crawler belt wound on the driving wheels and then transmitted to the driving wheels through the tractor body by the wheel axle. When the driving force is sufficient to overcome the rolling resistance and the traction resistance of the attached agricultural implement, the thrust wheels roll forward on the upper surface of the track, thereby causing the tractor to travel forward. The track is continuously rolled to the front by the driving wheel and then laid on the ground by the guide wheel, so that the thrust wheels can continuously roll on the track laid by the track. It is known that a track-type tractor performs work by interaction between a track and the ground through a driving wheel by a driving torque, and the driving force is larger than the sum of rolling resistance and traction resistance.

Nowadays, more and more crawler tractors are applied to industrial and agricultural production, and a hub assembly of a driving wheel requires high strength, rigidity, ductility, wear resistance and system reliability and needs special design and processing.
