Abstract

The invention relates to agricultural and tractor engineering. The purpose of the invention is to increase operational reliability by obtaining a variable center-to-center distance along the ridges of the track. This goal is achieved by the fact that in the caterpillar tractor including the casing 6, the articulated caterpillar trolley 5, the rigidly mounted final drive 2, the articulated caterpillar track 3, the spring-loaded track rollers 4 and the drive wheel 1, removable movable bushings 7 are installed in the sockets of the wheel 1, moreover, a clearance is provided in each slot for mounting the resilient member. 2 ill.

Description

The invention relates to agricultural and tractor engineering.

The aim of the invention is to increase operational reliability by obtaining a variable center-to-center distance along the ridges of the track

In FIG. 1 is a side view of a track wheel; in FIG. 2 is a section AA in FIG. 1.

The wheel 1, placed on the final drive 2, interacts with the caterpillar belt 3, on which the rollers 4 are mounted, mounted on the caterpillar truck 5, hingedly connected to the housing b.

A removable movable guide 7 is installed in the peripheral cavities of the wheel rim 1, between which there is a gap for installing an elastic element 8, which is limited from axial movement by the shoulder of the guide 7 and the washer 9 fixed by the spring ring 10. The ridge B of the track 4 enters the hole B removable guide rail 7.

The caterpillar wheel works as follows.

Torque from the final drive 2 enters the wheel 1, on the rim of which in the peripheral cavities there are removable movable guides 7 with elastic elements 8, fixed by washers 9 and spring rings 10. In the process of movement, the track ridge B

enters the hole of the removable movable guide 7 of the wheel 1.

In operation, due to the extension of the track 3, the center-to-center distance between the ridges B of the track 3 is violated, these disturbances are compensated by the movement of the removable guide 7, which provides the elastic member 8. Thus, the gearing of the wheel with the track is corrected. In case of wear of the guide 7 or other element 8, they can be easily replaced.

The proposed caterpillar track wheel, which provides correction of the center-to-center distance of gearing with the caterpillar track, can be widely used in agricultural and tractor engineering and will reduce operating costs.
