Description

[Detailed description of the invention] Caterpillar track plates for tracked vehicles The invention belongs to the track technology and the track as defined in the independent claim Regarding vehicles.

Caterpillars for tracked vehicles are rectangular and mutually tilt along their longitudinal side edges. Consisting of possible individual steel plates (caterpillar track plates). This type of track plate is used for example in International patent application No. PCT/CH39/'00057 describes their manufacturing method. Disclosed. The caterpillar track plate is formed as a rectangular plate, and its running direction is Crosswise to the long edge, e.g. protrusions at regular intervals and penetrations parallel to the edge In a perforated and interconnected track plate, one protrusion overlaps the protrusion on the adjacent plate. Interposed between them, the two plates are connected so that they can tilt relative to each other. Between the caterpillars or has many recesses formed inside it into which the teeth of the vehicle's drive wheels fit. Ru.

The caterpillar track plate has a flat surface facing the direction of the driving wheel, a driving plane, and is conveyed. One of the planes oriented toward the base includes a bottom surface. The driving plane is the caterpillar It has conventional guides to help orient the running rolls of the guiding struts. bottom The surface can be smooth or given a special shape, and its shape is mainly cross-shaped or tongue-like. , i.e., as an “active shape”. This rung or tongue is usually small. extending at least partially in a common direction to the direction of travel of the caterpillars, often with protrusions Since it is formed in a shape that protrudes between It protrudes in almost the same shape throughout.

The above-mentioned shaped portion is particularly thick in the running direction of the tracked vehicle (constructed so as to intersect with the running direction of the tracked vehicle). In the case of driving on a hard road surface, the holding performance is insufficient. Such a road surface is an example For example, it is a stepped road surface, which is neither smooth nor almost caterpillar. It is not a caterpillar board with a shape that extends in the direction of travel of the car, but it is anything else. Some kind of assistance is required. The graspability of the caterpillar is determined by the fact that the caterpillar plates are inside each other. This is particularly insufficient when the surface protrudes over the surface and forms a continuous running surface. However, this continuous run The running surface also has the advantage that contamination does not penetrate into other road surfaces. On the other hand, that depending on the area where the caterpillar descends onto the road surface or where it rises from the road surface. However, no support is obtained in the structure of the road surface that intersects the direction of travel over its entire length. A caterpillar was developed that could form a continuous running plane in places where it was impossible to There it was.

The object of the invention is to provide a rigid road surface with a structure oriented particularly towards the direction of travel and on a solid road surface. Caterpillars have improved grip on smooth road surfaces and have the advantage of a continuous plane. It consists in composing the la.

This problem is solved by the caterpillar feature description of the independent ring of claims. This will be explained below with reference to the drawings.

FIG. 1 is a bottom view of an embodiment of the caterpillar track plate according to the present invention; FIG. An elevational view of the track plate shown in the figure in the running direction: An elevational view of the track plate in the direction perpendicular to the running direction; FIG. FIG. 7 is a bottom view of another embodiment of the Tapira track plate.

The central idea of this invention is that the bottom surface of the caterpillar track plate faces the running direction of the caterpillar. at least one bottom groove formed at right angles to the long edge of the groove and substantially parallel to the long edge thereof. Therefore, it is divided. This bottom groove is preferably in the shape of a waterway. , is formed in a ``negative contour'' instead of the ``positive contour'' mentioned above, and is formed approximately in the center of the bottom surface. has been done. The bottom part formed on both sides of this groove may be smooth or have a shaped part. , the same depth as the negative contour extending over both sides of the groove, or deeper. That is appropriate.

Figure 1.2.3 shows an embodiment of the present invention, and Figure 1 shows the bottom of the caterpillar track plate. A top view of the surface, FIG. 2, a side view in the direction of travel showing the bottom surface 2 facing upwards; and Figure 3 are side views transverse to the direction of travel, again with the bottom surface facing upwards. 2 is shown.

The caterpillar track plate l in Fig. 1 moves the forward running direction of the vehicle from the bottom to the top in Fig. 1. The case is shown in the direction of arrow I. Each of the longitudinal edge lines of the track plate 1 has an edge line. Two protrusions 10.1.2 with through holes 11.3 parallel to The tracks are protruded from each other in staggered positions, and the individual caterpillar track plates are connected to a series of tracks. It serves to connect to Tapira. As shown in Figure 3, the bottom surface is not flat and approximately 15 ~20” slope and such a shape of the bottom surface 2 allows the caterpillar track plate to A continuous running plane in the tilting area is achieved.

A bottom groove 2 in the form of a straight water channel is provided approximately in the center over the entire length of the bottom surface of the crawler plate. 0 is formed, and the bottom surface portions 21.1 and 2 formed on both sides thereof are It is shaped like a crossbar or beam over its length.

In still other embodiments, other shaping elements are added to the bottom surface, typically this shape. The depth of the bottom groove is not parallel to the bottom groove (the depth of the bottom groove is at least corresponds to the depth of the shaped element.

FIG. 4 illustrates the bottom surface of this type of embodiment. In addition to the channel-shaped bottom groove 20, The bottom surface portion has a shaped portion extending from the bottom groove to the protrusions 10.1 to 10.4.

Further, the shaped grooves 22.1 to 8 are inclined at, for example, 45° with respect to the running direction, and is oriented in a direction towards the central area of the bottom surface 2. This allows the bottom groove to The bottom surface portions divided into 20 sides are polygonal in shape and completely separated from each other. The island-shaped part 23.1 becomes 23.11, and its side line is parallel to and perpendicular to the running direction. , and each sloped edge.

The caterpillar made of the above-mentioned caterpillar track plate has various advantages, and at least Although it has the basic surface of a conventional crawler plate, it has the advantage that the surface pressure does not become excessive. Ru.

The caterpillar of the present invention is particularly suitable for small and medium-sized tractors.

The material of the caterpillar track plate is preferably metal, but synthetic resin, preferably reinforced Synthetic resins can also be used.
