SU1229114A1 - Hingeless track of vehicle - Google Patents

Description

FIELD: transport engineering; namely to tracked vehicles.

The purpose of the invention is to increase the reliability of the track.

FIG. 1 shows a hingeless caterpillar, butonoidal section; in fig. 2 is a section A-A and FIG. one; in fig. 3 - not shown, side view; pas figs. 4 - section BB in FIG. 3; in fig. 5 top part Poner chips, top view.

The caterpillar caterpillar consists of three flexible elements connected by lines 2 installed on the upper side of the flexible elements. At the same time, the flexible element consists of an average flat belt 3, an upper belt 4 with elastic pushes in height, a large crossbar cross section, a lower mite 5 with groups, exceeding TOJinuiny linings 6. Flexible elements are tilted to a crossbar with a number of bolts 7 and pads 6 and 8. At the same time, the bridges are angled with rounded edges. Each pad 6 has recesses 9 for bolt heads. Each cross member 2 is formed by two parts 10 and 11 of a U-shaped cross section, facing each other with an open side and forming an equal strength element, due to the variable cross section of both parts. Transverse ends 2 are bent upwards. In addition, the ends of the upper part 11 of the cross member 2 form directions 1OH1, and ridges 12, for which they are bent upward, rounded and rigidly attached to the pinch part 10 of the cross member 2 (Fig. 3 and 4).

The caterpillar works the following 11, in the image.

forming together a treadmill. When moving along the soil, due to the absence of developed ground chains and the presence of bent upward ends of crossbars, its mechanical destruction is insignificant.

When driving on paved roads, the caterpillar acts with it by protruding belt lugs of the belt 5, which ensures smooth, quiet movement without any damage to the surface. The rounded edges of the plates 6 do not damage the belt 5 when they are bent. The presence of the recesses 9 on the plates 6 prevents the heads of the bolts 7 from wear. The guide ridges 12 of the upper part 11 of the cross member, rigidly attached to the lower part of the cross member 10, ensure reliable operation of the caterpillar during maneuvers with low energy consumption for friction of the rollers 13 against the ridges 12 due to rounding; the latter.

The application of the proposed caterpillar makes it possible to increase the reliability and durability of the caterpillar through the implementation of ridges and a flexible element, which consists of several ribbons, inside of which contains nodushki, and outer - hand ties, which eliminates wear and deformation of linings and bolt heads, improves d) capability The absence of contact between the pavement and the metal parts of the caterpillar eliminates the possibility of damage to the pavement, and also makes it possible to simultaneously increase the speed of movement during transport operations and, consequently, the performance. In addition, the shape of the guide ridges helps to reduce the metal consumption of the caterpillar.
