Abstract

The invention relates to an axle mount for utility vehicles, comprising a carrier unit and a protective unit, wherein the carrier unit has a first fastening region for the fixing of a utility vehicle axle thereto and has, arranged adjacent to said fastening region, a receiving region for receiving chassis systems, and wherein the protective unit is arranged on the carrier unit such that the receiving region is enclosed transversely with respect to an axial direction by the carrier unit and by the protective unit, in such a way that the ingress of foreign bodies into the receiving region is prevented.

First claim

1 . An axle mount for commercial vehicles, comprising:
a carrier unit; and a protective unit; wherein the carrier unit has a first fastening region for the fixing of a vehicle axle thereto and has, arranged adjacent to said fastening region, a receiving region for receiving chassis systems; and wherein the protective unit is arranged on the carrier unit such that the receiving region is enclosed transversely with respect to an axial direction by the carrier unit and by the protective unit, in such a way that the ingress of foreign bodies or foreign matter into the receiving region is prevented or obstructed; and wherein the protective unit is positively and frictionally fixed at the carrier unit.

2 . The axle mount of claim 1 ,
wherein the protective unit is fixed at the carrier unit at at least two fastening regions, which fastening regions are spaced apart.

3 . The axle mount of claim 1 , wherein the protective unit has a surface area and a support area reinforcing the surface area,
wherein the support area has a higher bending stiffness transversely with respect to the axial direction than the surface area, and wherein the surface area preferably has an extension along the axial direction, which is at least as large as the extension of the carrier unit in the axial direction.

4 . The axle mount of claim 3 ,
wherein the surface area of the protective unit is arranged on that side of the support area opposite the receiving region, and wherein the surface area is an expendable part and is fixed at the support area by a releasable connection.

5 . The axle mount of claim 3 ,
wherein the support area comprises a safety bar, which protects the surface area against the influence of large bodies or matter and against ground contact.

6 . The axle mount of claim 1 ,
wherein the protective unit at least over certain portions encloses the receiving region in a plane lying transversely with respect to the axial direction.

7 . The axle mount of claim 1 ,
wherein the carrier unit comprises a second fastening region for fixing the carrier unit at the vehicle frame of a commercial vehicle, and a third fastening region, at which a spring element may be brought into engagement, and wherein the receiving region and the protective unit are arranged between the first fastening region and the second fastening region of the carrier unit.

8 . The axle mount of claim 7 ,
wherein the protective unit is adapted to at least partially absorb forces and bending moments acting between the receiving regions.

9 . The axle mount of claim 1 ,
wherein the protective unit is designed such that it envelops the receiving region so as to lower the air resistance of the commercial vehicle.

10 . The axle mount of claim 1 ,
wherein the protective unit has cavities which allow the passage of cooling air into the receiving region so as to avoid overheating of the chassis systems.

11 . The axle mount of claim 1 ,
wherein the protective unit comprises a combination of a metal and a fiber-reinforced composite material.

12 . The axle mount of claim 3 ,
wherein the surface area of the protective unit comprises a plurality of surface segments fixed at the support area.

13 . The axle mount of claim 1 , having a cross-sectional shape, which in the area of the protective unit at the height of the receiving region differs from the cross-sectional shape in the area of the protective unit at the height of the first fastening region.
