Abstract

Use The invention relates to tractor engineering and can be used in industrial tractors. The invention allows to increase the traction and coupling properties by providing a more uniform pressure diagram. The essence of the device is a support 8 mounted in a carriage and supporting 2 rollers, a tension device with a spring shock absorber and a track mechanism 7 of the track 6, the drive wheel 5 and the track 6 enclosing it, while the tensioning device is made in the form of a block 10 carrying at least three rollers 11, the axes of which are located in an arc of a circle. The device allows for rigid installation of the support rollers p place one additional roller 9, and with an elastic installation of the support rollers - two additional rollers 11, 12, one of which is included in the sprung tension unit 10 The rollers of the tension device and the additional ones can be unified with the supporting ones 1 z p, 2 il. /; fe 00 go from 00 vi to

Description

Figure 1

The invention relates to mechanical engineering and can be used in i

mainly in the field of industrial tractors.

The aim of the invention is to remedy these drawbacks, namely, increasing the traction and coupling properties with a constant longitudinal base of the vehicle by providing a more uniform pressure plot

In FIG. 1 schematically shows a running system with rigidly mounted track rollers; Fig. 2 is a running subject with resiliently mounted questionable rollers.

The device (FIG. 1) comprises a housing 1 in the form of either a vehicle frame or a running carriage frame; two supporting rollers 2; a compression mechanism in the form of a spring shock absorber 3 with an emphasis 4 in the housing 1, a drive wheel 5, a track 6, a track tensioning mechanism 7, p the support rollers rigidly mounted on the housing 8, an additional rigidly mounted (similar to the support rollers 8) support roller 9, a tension device in the form of a tension unit 10 consisting of four rollers 11. whose axes are located at the circumference in the support bracket 12, connected ohm with a movable carriage 13, which is mounted on the guides 14 of the housing 1

The device (FIG. 2) comprises a housing 1 in the form of either a vehicle frame or a running carriage frame, two supporting rollers 2, a spring shock absorber 3 with a stop 4 in the housing 1, a drive wheel 5, a track 6, a track tensioning mechanism 7, five sprung supporting rollers 8 mounted on balancers 9, in the axes of swing of which torsiogs 10 are mounted, two additional sprung supporting rollers 11 and 12, one of which (pos. 11) is installed similarly to the supporting rollers 8. the second supporting additional roller (pos. 12) is installed in the support sprung tensioning block 13, consisting of three rollers 14 and an additional support roller (key 12), the axes of which are located around the circumference, and installed in the support bracket 15. the axis of the latter is mounted in a movable carriage 16 installed in the guides 17 of the housing 1 (or undercarriage), and a torsion 18 is installed in the axis of the support bracket 15, and the movable carriage 16 through the tensioning mechanism 7 abuts against the spring shock absorber 3 with the stop 4 in the housing 1
