Abstract
The subject of the present invention is an axle system for the articulated arrangement of vehicle axles in motor vehicles, comprising an axle strut body (1) and at least one joint body (2), with said axle strut body (1) having recesses (7, 8) that are formed in the end regions (5, 6) to receive the joint body (2). To create an axle system that can be produced cost-effectively and without additional work steps and that has a low rate of wear even under high dynamic and static loads, the present invention proposes that the axle strut body (1) and the joint bodies (2) each be made as a one-piece closed hollow section, with the joint bodies (2) being pivot type and set into the recesses of the axle strut body (1) in a form-fit and/or friction-locked manner.

Axle system for an articulated arrangement of vehicle axles in motor vehicles, comprising an axle strut body (1) and a joint body (2), wherein the axle strut body (1) has a recess (7) formed in an end region (5) for receiving the joint body (2),
- characterized in that
- the axle strut body (1) and the joint body (2) are each made as a one-piece closed hollow section, wherein the joint body includes a first portion that is inserted into the recess (7) of the axle strut body (1) in form-fit or friction lock manner and a second portion that extends outwardly of the recess (7) to form a pivot,
- the recess (7) of the axle strut body (1) having flanged collar-shaped edges (12).
An apparatus for an articulated arrangement of vehicle axles in motor vehicles, the apparatus comprising:
- an axle strut body having a longitudinally extending central region and first and second end regions, a first recess extending laterally through the first end region and a second recess extending laterally through the second end region, the axle strut body being formed from a one-piece, hollow tubular member and including a cavity that extends from the first end region to the second end region;
- and
- first and second joint bodies, each of the first and second joint bodies having a central region and first and second end regions, each of the first and second joint bodies being formed from a one-piece, hollow tubular member and including a cavity that extends from the first end region to the second end region,
- the first joint body being received in the first recess of the axle strut body, the central region of the first joint body being secured within the first recess and at least one of the first and second end regions of the first joint body extending outwardly of the first recess,
- the second joint body being received in the second recess of the axle strut body, the central region of the second joint body being secured within the second recess and at least one of the first and second end regions of the second joint body extending outwardly of the second recess,
- a buffer separating the central region of the first joint body from the first recess, the buffer being formed from a resilient material,
- the first recess receiving at least one ring for maintaining the buffer in the first recess.
