Problems solved by technology

[0006] Since the sealing element, typically a square seal ring, when fastened between the cartridge bottom plate and the housing of the compressed air production unit as is known from practice, must rotate together during tightening, due to different frictional influences during tightening Large fluctuations in the torque occur and damage or twisting of the sealing element occurs, which in turn leads to leakage

Embodiment Construction

[0030] The same elements are denoted by the same reference numerals in all figures.

[0031] figure 1A detailed view of a section of a desiccant cartridge according to an exemplary embodiment of the invention is shown here. figure 1 In particular, a section of the radially outer lower region of the desiccant cartridge 1 is shown. The interior of the desiccant cartridge 1 can be constructed in a manner known per se, for example as described in the laid-open documents DE 10 2013 103 066 A1, DE 10 2012 105 137 A1 and DE 10 2007 034 435 A1. For example, the reference numeral 13b designates an oil filter formed by a fleece and the reference numeral 13 designates an inner container for a desiccant, of which only a small part can be seen.

[0032] In a manner known per se, the cartridge housing of the desiccant cartridge has a basin-shaped or cup-shaped cover 5 , which delimits the cartridge housing upwards, and a cartridge bottom 2 , which delimits the cartridge housing downwards....

Abstract

The invention relates to a device for releasably fastening a desiccant cartridge on a housing of a compressed air production device of a vehicle, in particular a commercial vehicle. The device comprises at least one fixing piece (7) having a first section (8) and a second section (9; 29; 39; 49), the first section and the flanged piece ( The end region (4a) of 4) and the end region (5a) of the cartridge cover (5) are rolled into connecting folds (6), from which the second section protrudes outwards.

Description

technical field [0001] The invention relates to a device for the detachable fastening of a desiccant cartridge to a housing of a compressed air production device of a motor vehicle, in particular a truck. Background technique [0002] In particular, compressed air systems in commercial vehicles require so-called air preparation systems if they are connected downstream of the air compressor. In particular, the air is dried and filtered, and the oil components are separated off. These processes all take place in so-called desiccant cartridges, roughly speaking, consisting of a bottom plate with openings for the flow of air through and a cup-shaped or basin-shaped cover, the bottom plate and the The covers are fixedly connected to each other. Moisture-adsorbing granules are present therein, which draw moisture away from the air flowing through. Such pellets have only a limited service life when used in commercial vehicles. The reason for this is that the oil mist contained ...
