Hingeless rubber-reinforced track

FIELD: transport.

SUBSTANCE: hingeless rubber-reinforced track contains reinforcing elements (1) performed conjointly with guides (2), steel-wire cord made as cable (3) and supporting surface (6) with grousers (7). The guides (2) are located at certain distance from each other longwise. Reinforcing element (1) is made of resilient material in the form of cramp with turned in one direction ends (8), with straight segment (9) between them and is made of bar spring steel by hot forming. Turned in one direction ends (8) of reinforcing element is not conjointly cured in rubber (4) in single endless belt.

EFFECT: higher pneumatic tire traction.

The invention relates to a transport machine-building, namely the suspension systems of wheeled tractors and harvesting machines converted half-tracks (caterpillar) stroke.

Known rubber-metal caterpillar to re-equip the tractor TEF-20 semi-caterpillar (Department of mechanization and electrification of agriculture of the Ministry of agriculture of the USSR. "New tractors and agricultural machines. The results of the tests 1957. Issue I. M., 1959, p.63-65), containing a rigid metal U-shaped povazay, envelopes of cross-section profile pneumatic tyres drive wheel of the tractor, and a tension wheel, riveted on both sides focusarea endless rubber belts, forming an endless rubber-metal caterpillar.

One of the drawbacks of this caterpillar is the slip of the drive wheel of the tractor relative to the rubber-metal caterpillar due to the weak coupling between them.

In addition, in the area between the leading and idler wheels at the base of insufficient bearing surface caterpillars because there is space between pokozachene that offer waterlogged soil, contributing to the immersion of the tractor to the ground, destroying it.

Also known rubber-metal caterpillar for retrofitting tracto is and MTZ-5LC on semi-caterpillar (Brasero, Bpetersen, Negrepelisse. Domestic tractors. The Handbook. State scientific and technical publishing house of the engineering literature. M.-L., 1962), consisting of two rubber-metal tracks and two idler wheels with tensioning devices.

Tractor MT3-5LC compared to tractor TEF-20, equipped with a similar rubber-metal caterpillar has a larger diameter and the width of the drive wheel, so his grip pneumatic tires of rubber-metal caterpillar will be significantly higher, but not enough for tractor MTZ-5LC without spinning the drive wheels relative to the caterpillar.

The free space between pokozachene caterpillars allows waterlogged soil to penetrate through them, contributing to the immersion of the tractor to the ground, destroying it.

The purpose of the invention is to increase the adhesion of the pneumatic tire of the drive wheel of the vehicle, such as tractor or harvesting machine, a converted half-tracks (caterpillar) stroke.

This objective is achieved in that the reinforcing element is made of elastic material in the form of a bracket with a curved one-side ends with a straight section between them, and made, for example, from a strip of spring steel, hot-stamping, while curved in one direction the ends of the reinforcing element, doing what their role napravila, not vulcanized for one in rubber in a single endless belt, and the lug is made at the base of the circular cone and located on the lines forming on a support surface of an endless belt of the figure in the form of a "Christmas tree".

Thus, the claimed caterpillar hingeless rubber meets the criterion of "novelty"

The features distinguishing the claimed technical solution to the prototype, in other technical solutions in this field of technology have been identified that leads to the conclusion that the claimed caterpillar hingeless rubber meets the criterion of "substantial differences".

Figure 1 shows the proposed caterpillar in part of a converted vehicle PA Halftrack (caterpillar) stroke, left side view; figure 2 is a reinforcing element, General view, in perspective view; figure 3 is a section a - a of figure 1; figure 4 is a cross - section In figure 1; figure 5 is a General view in the context of the proposed caterpillars from the side of the tracks, in a perspective view; figure 6 is a General view in the context of the proposed caterpillars from the side of the lug, in a perspective view.

Caterpillar hingeless rubber (figure 1) contains reinforcing elements 1 (figure 2), made in one with napraviteley 2 and placed at a certain distance from each other along the length of the steel cord (figure 3, figure 4), covering the reinforcing elements 1 SN is Rui, vulcanized for one in rubber 4 in a single endless belt having a running track 5 (figure 5) and the support surface 6 (6) lug 7.

The reinforcing element 1 (figure 2) is made of elastic material in the form of a bracket with a curved one-side ends 8 direct 9 plot between them and made, for example, from a strip of spring steel, hot-stamping, while curved in one direction, the ends 8 of the reinforcing element 1, the role of napravila 2, not vulcanized for one in rubber 4 in a single endless belt, and the lugs 7 (6) made in the base of the circular cone and located on lines 10, forming on a support surface 6 of an endless belt of the figure in the form of a "Christmas tree".

In part of a converted vehicle, such as tractor or harvester, half-tracks (caterpillar) stroke, (1) caterpillar hingeless rubber around the pneumatic tire 11 of the drive wheel 12 and the pneumatic tire 13 idler wheel 14.

When the vehicle, such as tractor or harvesting machine, a converted half-tracks (caterpillar) stroke, caterpillar hingeless rubber (figure 1) around the pneumatic tire 13 idler wheel 14 and the pneumatic tire 11 of the drive wheel 12, which result is in motion caterpillar due to the friction surfaces running tracks 5 and bent to one side of the ends 8, role of napravila 2, which are pressed against the side surface of the pneumatic tire 11 (figure 3) due to the fact that the straight section 9 of the reinforcing element 1 (figure 2) under the action of the tension caterpillars and weight of the vehicle, together with rubber 4 and treadmills 5 (figure 5), caves in and takes the form of the cross section of the outer surface of the pneumatic tire 11 (3), "forcing" bent to one side, the ends 8 role of napravila 2, not vulcanized for one in rubber 4 in a single endless ribbon, snuggle up to the side surface of the pneumatic tire 11.

After the termination of the interaction of the pneumatic tire 11 of the drive wheel 12 with caterpillar reinforcing element 1 together with rubber 4 and treadmills 5 take the initial position (figure 4), and curved in one direction, the ends 8 role of napravila 2, away from the side surface of the pneumatic tire 11 of the drive wheel 12.

On the ground the caterpillar rests via the supporting surface 6 and the lugs 7.

The host 12 and the tensioning wheel 14 roll on treadmills 5 (figure 4, figure 5), pressing the caterpillar to the soil, providing the movement of the vehicle, a converted half-tracks (caterpillar) stroke.

The presence of the metal cords in the form of a cable 3, and the reinforcing elements 1 made of the other material in the form of a bracket with a curved one-side ends 8, direct area 9 between them, provide additional force clutch pneumatic tire 11 of the drive wheel 12 with caterpillar, to save her strength.

Due to the fact that curved in one direction, the ends 8 role of napravila 2, not vulcanized for one in rubber 4 in a single endless belt, helps to reduce the overall weight of the caterpillar.

The implementation of the lug 7 at the base of the circular cone and the location of their lines 10, forming on a support surface 6 of an endless belt of the figure in the form of a "Christmas tree", do not hinder the deformation of the crawler belt in cross-section under the action of the pneumatic tire 11 of the drive wheel 12, and also improves the grip lug 7 with the soil.

The use of the proposed caterpillars hingeless rubber will increase the grip pneumatic tyres drive wheel of the vehicle, such as tractor or harvesting machine, a converted half-tracks (caterpillar) stroke, with caterpillar hingeless rubber.
