Abstract

A device is provided for the detachable fastening of a drying agent cartridge to a housing of a compressed-air treatment installation of a vehicle, in particular of a utility vehicle. The device includes a crimped formation on the cartridge base of the drying agent cartridge, which crimped formation has an abutment surface, and an insertion opening on the housing of the compressed-air treatment installation, into which insertion opening the crimped formation can be inserted at least in sections, and in which insertion opening the crimped formation, in the inserted state, is secured in an axial direction by way of a form fit.

First claim

The invention claimed is:

1. A device for the detachable fastening of a drying agent cartridge to a housing of a compressed-air treatment installation of a vehicle, comprising:
a crimped formation on the cartridge base of the drying agent cartridge, wherein the crimped formation has an abutment surface; and
an insertion opening on the housing of the compressed-air treatment installation, wherein the crimped formation can be inserted into the insertion opening at least in sections and, in the inserted state, is secured in an axial direction by way of a form fit;
wherein the connecting seam between the cartridge base and a cartridge housing cover includes a widening, the widening formed by a radially extending crimped lug which circumferentially surrounds the crimped region between the cartridge base and the cartridge housing cover and formed by a 180° crimped formation of a crimped plate of the cartridge base, wherein the insertion opening is arranged such that the crimped lug can be inserted at least in sections into the insertion opening.

2. The device according to claim 1 , wherein the crimped formation that can be inserted into the insertion opening is a crimped connecting seam between the cartridge base and a cartridge housing cover.

3. The device according to claim 2 , wherein the connecting seam is formed by a U-shaped crimped formation of a crimped plate of the cartridge base and by a standing seam, arranged in the U-shaped crimped formation, of the cartridge housing cover, wherein limbs of the U-shaped crimped formation extend in a radial direction.

4. A device for the detachable fastening of a drying agent cartridge to a housing of a compressed-air treatment installation of a vehicle, comprising:
a crimped formation on the cartridge base of the drying agent cartridge, wherein the crimped formation has an abutment surface; and
an insertion opening on the housing of the compressed-air treatment installation, wherein the crimped formation can be inserted into the insertion opening at least in sections and, in the inserted state, is secured in an axial direction by way of a form fit;
wherein a crimped plate of the cartridge base forms a hook-like crimped formation, having a first section which extends away from a cartridge housing cover in an axial direction, and having a second section which adjoins the first section and which extends in a radial direction, wherein the insertion opening is arranged on the housing such that the second section can be inserted into the insertion opening and, in the inserted state, secures the cartridge in the axial direction by way of the form fit.

5. The device according to claim 1 , wherein the crimped formation, which can be inserted at least in sections into the insertion opening, has a relative-rotation prevention means.

6. The device according to claim 5 , wherein the relative-rotation prevention means is formed by a hole in the crimped formation and by a locking element, in particular a locking pin, which is seated in the hole.

7. The device according to claim 5 , wherein the relative-rotation prevention means is formed as a flattened portion, in sections, of the crimped formation.

8. The device according to claim 1 , wherein the drying agent cartridge can be fastened to the housing of the air treatment installation only by way of a form fit.

9. The device according to claim 1 , wherein the drying agent cartridge has no thread for the purposes of screwing the cartridge to the housing of the air treatment installation.

10. A motor vehicle comprising:
a device for the detachable fastening of a drying agent cartridge to a housing of a compressed-air treatment installation of the utility vehicle, the device comprising:
a crimped formation on the cartridge base of the drying agent cartridge, wherein the crimped formation has an abutment surface; and
an insertion opening on the housing of the compressed-air treatment installation, wherein the crimped formation can be inserted into the insertion opening at least in sections and, in the inserted state, is secured in an axial direction by way of a form fit;

wherein the connecting seam between the cartridge base and a cartridge housing cover includes a widening, the widening formed by a radially extending crimped lug which circumferentially surrounds the crimped region between the cartridge base and the cartridge housing cover, and is formed by a 180° crimped formation of a crimped plate of the cartridge base, wherein the insertion opening is arranged such that the crimped lug can be inserted at least in sections into the insertion opening; or
wherein a crimped plate of the cartridge base forms a hook-like crimped formation, having a first section which extends away from a cartridge housing cover in an axial direction, and having a second section which adjoins the first section and which extends in a radial direction, wherein the insertion opening is arranged on the housing such that the second section can be inserted into the insertion opening and, in the inserted state, secures the cartridge in the axial direction by way of the form fit.

11. The device according to claim 1 , wherein the drying agent cartridge has no thread arranged on the cartridge base for the purposes of screwing the cartridge to the housing of the air treatment installation.
