Abstract

A crawler web for crawler belts of crawler vehicles, in particular for ski slope vehicles or cross-country trackers, is proposed, which is fastened, transversely to the running direction, to mutually parallel bands oriented in the direction of travel. The bands being an elongate basic body which has a sheet-like support connected in the direction of the bands. The object of the invention is to provide a crawler web which can be adapted individually for different applications and can be produced at comparatively low costs. The object is achieved in that the basic body encompasses, in cross section, two side legs with a connecting web arranged between them, at least one side leg approaching the other in such a way that a cutting edge can be inserted between the legs.

Claims

1. A crawler web for use in a crawler belt on a crawler vehicle having at least two mutually parallel bands oriented in the direction of travel of the vehicle, the crawler web oriented transversely to the direction of travel and comprising:

a cutting member having a cutting edge; and

an elongated body member defining a cross sectional shape having;

a first side leg having a first portion;

a second side leg having a second portion oriented relative to said first portion such that at least one side leg approaches the other; and

a connecting web that connects said first side leg to said second side leg,

wherein, after the at least one side leg approaches the other, said side legs merge into a first and second side leg portion, respectively, in which each respective portion runs at a distance from the other portion and said cutting edge is insertable between the legs.

2. A crawler web according to claim 1, wherein, after the at least one side leg approaches the other, each respective side leg portion runs essentially parallel to the other portion.

3. A crawler web according to claim 1, wherein the connecting web serves to support the bands of the crawler belt.

4. A crawler web according to claim 2, wherein the respective side leg portions are oriented perpendicularly to the connecting web.

5. A crawler web according to claim 2, wherein the two side legs merge into said respective side leg portions through at least one bend.

6. A crawler web according to claim 2, wherein the respective side legs are arranged in a U-shaped manner, and said first side leg is guided through a first bend in said first side leg portion and merges with said second side leg through a second bend in said second side leg portion.

7. A crawler web according to claim 1, wherein said cutting edge is inserted fixedly between said first and second portions by at least one of riveting, welding, and screwing.

8. A crawler web according to claim 1, wherein the cutting edge runs continuously through the elongate body member, from said respective side leg portions to said connecting web.

9. A crawler web according to claim 8, wherein the cutting edge is fastened to the connecting web through a screw connection arranged in a region of said connecting web and in a prepared portion of said cutting edge.

10. A crawler web according to claim 1, wherein a connector for fastening the crawler web to the bands of the crawler belt is provided in a region of the connecting web.

11. A crawler web according to claim 10, wherein the connector comprises threaded bores in the connecting web.

12. A crawler web according to claim 10, wherein said cutting edge is fastened to the connecting web by a fastener and said fastener for the connecting web also serves as the connector for the crawler web.

13. A crawler web according to claim 8, wherein said cutting edge is fastened through retention by the connecting web.

14. A crawler web according to claim 13, wherein said cutting edge is fastened through a longitudinal groove in the connecting web the cutting edge being at least partially guided in said longitudinal groove.

15. A crawler web according to claim 10, wherein the connector comprises a threaded strip inserted into the elongated body with corresponding orifices adaptable for introduction of a screw thread in the connecting web.
