Abstract

A connection bridge device is suggested for connecting a multipoint link to a vehicle axle, particularly a multipart vehicle axle. The connection bridge device comprises at least one base body for receiving and dissipating forces and/or torques transmitted between the vehicle axle and the multipoint link, at least one axle fastening unit for fastening the base body to the vehicle axle, and at least one link coupling unit for coupling the base body to the multipoint link, which link coupling unit is intersected by a main extension plane of the base body.

First claim

The invention claimed is:

1. A connection bridge device for connecting a multipoint link to a multipart vehicle axle, comprising:
at least one base body for receiving and dissipating forces and/or torques transmitted between the multipart vehicle axle and the multipoint link;
at least one axle fastening unit configured to fasten the at least one base body to the multipart vehicle axle; and
at least one link coupling unit configured to couple the at least one base body to the multipoint link, wherein the at least one link coupling unit is intersected by a main extension plane of the at least one base body.

2. The connection bridge device according to claim 1 , comprising at least two link coupling units configured to couple the at least one base body to at least two coupling units of the multipoint link.

3. The connection bridge device according to claim 2 , wherein the at least one base body in a middle area remote of the at least one axle fastening unit extends perpendicular to the main extension plane farther than the at least two link coupling units.

4. The connection bridge device according to claim 1 , wherein the at least one base body has a maximum transverse extension perpendicular to the main extension plane in a middle area remote of the at least one axle fastening unit.

5. The connection bridge device according to claim 1 , wherein the at least one base body is formed at least partially as a hollow profile component.

6. The connection bridge device according to claim 5 , wherein the at least one base body has at least one stiffening rib.

7. The connection bridge device according to claim 6 , wherein the at least one base body has at least two stiffening ribs which together form an undercut.

8. A process for producing the connection bridge device according to claim 1 , wherein the connection bridge device is cast.

9. A connection system comprising:
at least one vehicle axle, configured as a multipart vehicle axle;
at least one connection bridge device configured to connect a multipoint link to the multipart vehicle axle, comprising:
at least one base body for receiving and dissipating forces and/or torques transmitted between the multipart vehicle axle and the multipoint link;
at least one axle fastening unit configured to fasten the at least one base body to the multipart vehicle axle; and
at least one link coupling unit configured to couple the at least one base body to the multipoint link, wherein the at least one link coupling unit is intersected by a main extension plane of the at least one base body,

wherein the multipart vehicle axle has at least one connection unit arranged separate from a central portion of the multipart vehicle axle for fastening the at least one connection bridge device.

10. The connection system according to claim 9 , wherein the multipart vehicle axle is a motorized axle, and the central portion comprises at least one drive unit.

11. The connection system according to claim 9 , wherein at least one multipoint link, is configured as a three-point link or a four-point link.

12. A vehicle, comprising:
at least one connection bridge device comprising:
at least one base body for receiving and dissipating forces and/or torques transmitted between a vehicle axle and a multipoint link;
at least one axle fastening unit configured to fasten the at least one base body to the vehicle axle; and
at least one link coupling unit configured to couple the at least one base body to the multipoint link, wherein the at least one link coupling unit is intersected by a main extension plane of the at least one base body;

or
at least one vehicle axle, configured as a multipart vehicle axle; and
the at least one connection bridge device,
wherein the multipart vehicle axle has at least one connection unit arranged separate from a central portion of the multipart vehicle axle for fastening the at least one connection bridge device.
