Abstract

The invention relates to a bearing block assembly for hinging of a coupling rod to a carriage body. The bearing block assembly includes a bearing shell unit and a bearing block with a flange for connecting the bearing block assembly to the carriage body and has an open bearing shell receiving region for at least partial reception of the bearing shell unit. The bearing block assembly has at least one guide extending in a longitudinal direction over at least a section of the extension of the bearing block. The bearing shell unit connects to the bearing block via at least one tear-off element and/or at least one shear-off element and is movably guided on the at least one guide in a longitudinal direction relative to same when the connecting element is actuated, thereby releasing the connection between the bearing shell unit and the bearing block.

First claim

What is claimed is:

1. A bearing block assembly for hinging a coupling rod to a carriage body of a track guided vehicle, comprising:
a flange for connecting the bearing block assembly to the carriage body;
a bearing shell unit connected at least indirectly with the flange, the bearing shell unit including two retainers being arranged in horizontal vertically offset planes and configured for accommodating a vertically progressing common pivot pin or for accommodating respectively one vertically progressing rotary pin that is accordingly allocated to the respective retainer;
a bearing block including the flange and an open bearing shell receiving region in at least a longitudinal direction, the open bearing shell receiving region configured for at least partial reception of the bearing shell unit;
at least one guide extending in the longitudinal direction over at least a section of an extension of the bearing block;
wherein the bearing shell unit is connected to the bearing block via at least one of at least one tear-off element and at least one shear-off element, the bearing shell unit being movably guided on the at least one guide on the bearing block in the longitudinal direction when at least one of the at least one tear-off element and the at least one shear-off element is actuated, thereby releasing the connection between the bearing shell unit and the bearing block;
wherein the bearing shell unit includes at least one guidance region or at least one guide element for interaction with the at least one guide that extends in the longitudinal direction of the bearing block, thereby forming a guide system; and
wherein the connecting region and the guidance region on the bearing shell unit are formed by a solid profile element formed integral with the bearing shell unit extending in the longitudinal direction, wherein an outside circumference of the solid profile element includes a plurality of guide surfaces for guiding on the at least one guide of the bearing block, wherein the at least one tear-off element extends and the bearing shell unit is arranged in connection to the bearing block about the solid profile elements.

2. The bearing block assembly according to claim 1 , wherein the bearing shell unit is connected with the bearing block via at least one tear-off element that is aligned in the longitudinal direction of the bearing block.

3. The bearing block assembly according to claim 1 , wherein the flange includes at least one flange surface arranged at least partially in a horizontal plane and extending in the longitudinal direction and configured to connect with a plurality of complimentary contact surfaces on the carriage body.

4. The bearing block assembly according to claim 1 , wherein at least one of the bearing shell unit and the bearing block are configures as a single component.

5. The bearing block assembly according to claim 1 , wherein at least one of the bearing shell unit and the bearing block are a cast component.

6. The bearing block assembly according to claim 1 , wherein the bearing shell unit includes at least one connecting region for connection with the bearing block, the at least one connecting region having at least one single tear-off element arranged therein.

7. The bearing block assembly according to claim 6 , wherein at least one of the at least one connecting region, the at least one guidance region and the at least one guide element are angularly offset relative to one of the two retainers located in the bearing shell unit.

8. The bearing block assembly according to claim 7 , wherein a plurality of connecting sections of the connecting region are formed by a plurality of guidance sections of the at least one guidance region.

9. The bearing block assembly according to claim 1 , wherein the at least one guide on the bearing block includes at least one of a first guide surface, a second guide surface and a third guide surface, wherein the first guide surface limits an upward movement of the bearing shell unit in a vertical direction with a directional component perpendicular to the longitudinal direction, the second guide surface limits a downward movement of the bearing shell unit in the vertical direction with a directional component perpendicular to the longitudinal direction and the third guide surface limits a movement in a width direction of the bearing shell unit in a horizontal direction with a directional component perpendicular to the longitudinal direction of the bearing block.

10. The bearing block assembly according to claim 1 , wherein the guide system is formed by a positive connection between the bearing block and the bearing shell unit, wherein the positive connection has a clearance fit and a degree of freedom in the longitudinal direction.

11. The bearing block assembly according to claim 1 , wherein a length of the at least one guide on the bearing block is configured to prevent complete separation of the bearing shell unit from the bearing block after a maximum shift of the bearing shell unit relative to the bearing block in the longitudinal direction and actuation of at least one of the at least one tear-off element and the at least one shear-off element.

12. The bearing block assembly according to claim 1 , wherein the bearing shell unit is braced with the bearing block with at least one of the at least one tear-off element and the at least one shear-off element.

13. The bearing block assembly according to claim 1 , wherein the bearing block includes a tension stop formed integral with or connected to for support of the bearing shell unit when it is under a tensile stress, wherein the bearing shell unit is braced relative to the tension stop with at least one of the at least one tear-off element or the at least one shear-off element.

14. The bearing block assembly according to claim 1 , wherein the at least one tear-off element is at least one tear off bolt or at least one rivet.

15. The bearing block assembly according to claim 1 , wherein the at least one shear-off element is at least one bolt or at least one rivet.

16. The bearing block assembly according to claim 1 , wherein at least one of the bearing shell unit and the bearing block are symmetrical about a vertical plane along the longitudinal direction.
