Abstract

The present invention relates to a running gear chain (2), in particular a bogie chain (2), having a flexible body (20), preferably an elastomer body (20), which is closed in endless fashion, or closable in endless fashion, in a running direction (A). The running gear chain (2) according to the invention is characterized by a multiplicity of rigid transverse elements (24) which are connected to the outer side of the flexible body (20) and extend substantially transversely with respect to the running direction (A), wherein at least some of the rigid transverse elements (24), preferably all of the rigid transverse elements (24), are arranged so close together in the running direction (A) that, with a planar extent of the flexible body (20), two immediately adjacent rigid transverse elements (24) make contact in the running direction (A).

First claim

The invention claimed is:

1. A running gear bogie chain, comprising:
a flexible elastomer body, which is closed in an endless fashion and in a running direction;
a multiplicity of rigid transverse elements connected to an outer side of the flexible elastomer body and which extend substantially transversely with respect to a running direction and are arranged together in the running direction
the multiplicity of rigid transverse elements comprise a multiplicity of receptacles, wherein the multiplicity of receptacles are outwardly pointing;
the multiplicity of rigid transverse elements are connected to the outer side of the flexible elastomer body by vulcanization;
the rigid transverse elements designed as a U-shaped steel profile;
one or more profiled elements inserted into one or more of the multiplicity of receptacles; and
the multiplicity of rigid transverse elements are arranged close together in the running direction (A) that two immediately adjacent rigid transverse elements make contact in the running direction (A).

2. The running gear bogie chain as claimed in claim 1 , wherein the multiplicity of rigid transverse elements are connected to the outer side of the flexible elastomer body so as to be rowed up in the running direction without intervals.

3. The running gear bogie chain as claimed in claim 1 , wherein the individual rigid transverse elements are each designed to be short in the running direction such that the running gear chain is bendable around a running gear of a vehicle.

4. The running gear bogie chain as claimed in claim 1 , wherein the flexible elastomer body has a multiplicity of tension members that extend in the running direction and are embedded into the flexible elastomer body.

5. The running gear bogie chain as claimed in claim 4 , wherein the multiplicity of tension members comprise a cable, wherein the cable is selected from a group comprising a steel cable, a glass fiber cable and/or an aramid cable.

6. The running gear bogie chain as claimed in claim 1 , wherein an individual tension member of the multiplicity of tension members is formed over the entire width of the running gear chain or only over part of the width of the running gear chain, wherein at least one edge region in the transverse direction is/are formed free of the multiplicity of tension members.

7. The running gear bogie chain as claimed in claim 1 , wherein the flexible elastomer body has an inner profiling on its inner side at least partially in the transverse direction and/or in the running direction, wherein the inner profiling is formed in one piece with an elastomer material of the flexible elastomer body.

8. The running gear bogie chain as claimed in claim 1 , wherein at least one rigid transverse element comprises a material selected from the group consisting of aluminum, steel, and a glass-fiber-reinforced plastic.

9. The running gear bogie chain as claimed in claim 1 , wherein the multiplicity of receptacles are designed to receive a multiplicity of profiled elements.

10. The running gear bogie chain as claimed in claim 9 , wherein a longer profiled element of the multiplicity of profiled elements has a longer profile than adjacent profiled elements of the multiplicity of profiled elements.

11. The running gear bogie chain as claimed in claim 9 , wherein only a portion of the multiplicity of receptacles include the multiplicity of profiled elements.

12. The running gear bogie chain as claimed in claim 9 , wherein a first portion of the multiplicity of profiled elements are made of steel and a second portion of the multiplicity of profiled elements are made of an elastomer material.

13. The running gear bogie chain as claimed in claim 9 , wherein the multiplicity of profiled elements are made of glass-fiber-reinforced plastic.

14. The running gear bogie chain as claimed in claim 1 , the one or more profiled elements comprising elastomer to protect ground for travel on a concreted road.

15. The running gear bogie chain as claimed in claim 1 , the one or more profiled elements comprising steel to increase adhesion to the ground for off-road use.

16. The running gear bogie chain as claimed in claim 1 , the one or more profiled elements comprising elastomer profiled elements and profiled elements made of steel.
