Abstract

An assembly has a bearing bracket and a coupler or connection rod. The bearing bracket has an adapter to which the rod can be connected. A joint allows the adapter to swivel relative to the bracket, and the rod is attached to the adapter. The rod has a surface that extends in a plane at an angle relative to the longitudinal axis of the rod. The rod surface is held spaced apart from a surface of the bearing bracket by an elastic element. The surface of the rod contacts the surface of the bearing bracket, if a pushing force of a predetermined strength is applied to the rod. A group of parts of the bearing bracket are connected to the bracket such that the parts are set free to move relative to the bracket, if a pushing force of a predetermined strength is applied to the rod.

First claim

The invention claimed is:

1. An assembly with a bearing bracket and a rod, the bearing bracket comprising:
an adapter that is adapted such that the rod can be connected to it,
a bracket, wherein the bracket is one of a bracket for forming part of a car and a bracket configured for connection to a car of a multi-car vehicle,
a joint arranged in such manner that it allows the adapter to swivel relative to the bracket about at least one swivel axis, whereby the rod is attached to the adapter or is formed as one piece with the adapter and wherein the rod has at least one surface that extends in a plane that is at an angle relative to the longitudinal axis of the rod and
wherein the at least one surface of the rod is:
held spaced apart from a surface of the bearing bracket by an elastic element arranged between a first element and a second element of elements in the line of flow of force for transmitting forces acting along the longitudinal axis of the rod to the bracket that by its resilience keeps the first element spaced apart from the second element and whereby the surface of the rod comes into contact with the surface of the bearing bracket when a pushing force of a first predetermined strength is applied to the rod that overcomes at least a part of the resilience of the elastic element; and
wherein a group of parts of the bearing bracket, including at least the adapter and the joint, are connected to the bracket by at least one connection element adapted to shear off responsive to a pushing force of a second predetermined strength in such a manner that the group of parts is set free to move longitudinally relative to the bracket when the pushing force of the second predetermined strength is applied to the rod;
wherein the rod is one of a coupler rod and a connection rod.

2. The assembly according to claim 1 , further comprising an energy absorbing element that is deformed by the movement of a part of the group of parts set free to move longitudinally relative to the bracket when the pushing force of the second predetermined strength is applied to the rod.

3. The assembly according to claim 1 , wherein the surface that extends at an angle relative to the longitudinal axis of the rod is arranged above and/or below the horizontal plane that contains the longitudinal axis of the rod and/or left or right of the vertical plane that contains the longitudinal axis of the rod.

4. The assembly according to claim 1 , wherein a part of the group of parts set free to move longitudinally relative to the bracket has a cut-out that engages with a guide-bar that guides the movement of that part.

5. A bearing bracket for connecting a rod to a car, comprising:
an adapter that is adapted such that the rod can be connected to it,
a bracket forming part of a car or being a bracket suitable for being connected to a car of a multi-car vehicle,
a joint arranged in such manner it allows the adapter to swivel relative to the bracket about at least one swivel axis,
wherein the joint connects the adapter to a joint receiving part in such a manner that the adapter is set free to move relative to at least some parts of the joint receiving part in at least one direction when a pushing force of a first predetermined strength is applied to the adapter that points into this at least one direction, and
wherein the joint receiving part is connected to the bracket by at least one connection element adapted to shear off responsive to a pushing force of a second predetermined strength in such a manner that the joint receiving part is set free to move longitudinally relative to the bracket when the pushing force of the second predetermined strength greater than the first predetermined strength is applied to the joint receiving part; and
wherein the rod is one of a coupler rod and a connection rod.

6. The bearing bracket according to claim 5 , wherein the joint has at least one joint pin that is partially held in a receptacle of the joint receiving part, wherein the receptacle is provided by at least two parts of the joint receiving part, each of the at least two parts forming a part of a wall that delimits the receptacle, wherein the two parts are connected to each other by the at least one connection element that upon application of the force of the second predetermined strength can shear off.

7. The bearing bracket according to claim 5 , wherein the joint receiving part has at least one flange that is connected to the bracket by the at least one connection element that upon application of the force of the second predetermined strength can shear off.

8. The bearing bracket according to claim 5 , wherein the joint has a vertically extending joint pin that is connected to the joint receiving part and has a horizontally extending joint pin that is connected to the vertically extending joint pin and to the adapter.

9. The bearing bracket according to claim 5 , wherein the joint receiving part has at least two vertically extending flanges and whereby the two vertically extending flanges each have a horizontally extending cut-out that engages with the respective one of two guide-bar that are arranged facing inward into a hole formed in the bracket, through which hole the joint receiving part can move once it is set free to move longitudinally relative to the bracket, when the pushing force of the second predetermined strength is applied to the joint receiving part.

10. The bearing bracket according to claim 9 , whereby the cut-outs on the two vertically extending flanges and the two guide bars are arranged in such a manner that they can take up a momentum around a horizontal axis perpendicular to the longitudinal axis of the rod.

11. The bearing bracket according to claim 5 , further comprising an elastic element which connects the adapter to the joint receiving part in such a manner that the adapter is set free to move relative to at least some parts of the joint receiving part in at least one direction when the pushing force of the first predetermined strength is applied to the adapter that points into this at least one direction to overcome at least a part of a resilience of the elastic element.

12. The bearing bracket according to claim 5 , further comprising at least one first connection element which connects the adapter to the joint receiving part in such a manner that the adapter is set free to move relative to at least some parts of the joint receiving part in at least one direction when the pushing force of the first predetermined strength is applied to the adapter that points into this at least one direction to break the at least one first connection element.

13. An assembly, comprising:
a bearing bracket for connecting one of a coupler rod and a connection rod to a car, comprising
an adapter that is adapted such that the rod can be connected to it,
a bracket, the bracket either (a) forming part of a car or (b) being suitable for being connected to a car of a multi-car vehicle,
a joint arranged to allow the adapter to swivel relative to the bracket about at least one swivel axis,
wherein the joint connects the adapter to a joint receiving part in such a manner that the adapter is set free to move relative to at least some parts of the joint receiving part in at least one direction when a pushing force of a first predetermined strength is applied to the adapter that points into this at least one direction, and
wherein the joint receiving part is connected to the bracket by at least one connection element adapted to shear off responsive to a pushing force of a second predetermined strength in such a manner that the joint receiving part is set free to move longitudinally relative to the
