Definitions
- This invention generally relates to an air dryer and more specifically to a method and system for mounting a remote purge air dryer used in an air braking system.
- an air dryer In compressed air braking systems, such as those used on commercial vehicles, an air dryer is typically placed in line after the compressor and prior to the rest of the components, such as the compressed air reservoir or air brake units.
- the air dryer removes harmful contaminants, such as dirt, oil, oil vapor, water and water vapor, from the compressed air, and thus provides clean, dry air to the components of the brake system. Clean dry air increases the reliability and life of the brake system, thereby reducing maintenance costs.
- a typical air dryer used in air braking systems contains a desiccant canister, which includes an oil separator and a desiccant material that adsorbs water as the compressed air passes through it.
- the desiccant material can be regenerated by reversing the air flow and purging the material with dry air supplied from a purge air volume. As the dry air passes through the desiccant material the moisture that was previously adsorbed from the compressed air is transferred back to the air and expelled through an exhaust port.
- the purge volume may be either coupled with the brake system reservoir or contained in a separate purge air reservoir.
- Air dryers with a separate purge air reservoir may be either integrated or remote.
- An integrated air dryer system such as the Bendix AD-IS air dryer, has an air dryer with a self contained purge reservoir tank.
- a remote purge volume air dryer has the purge air reservoir located remotely from the air dryer.
- Remote purge volume air dryers are typically preferred over integrated air dryers, since integrated air dryers tend to be larger and more expensive to make.
- the size of an integrated air dryer limits the available mounting areas on the vehicle.
- the air dryer must be located far enough away from the compressor so that the temperature at which the air dryer will effectively remove moisture is not exceeded.
- the air line from the air compressor to the air dryer must slope downward and have as few bends as possible to prevent water from being trapped in the air line and freezing.
- air dryer canisters have a limited useful life and can only be regenerated a certain number of times before requiring replacement. To facilitate the periodic replacement of the air dryer canister, a convenient mounting location is desirable.
- a method and apparatus for mounting an air dryer assembly to a vehicle in one of several possible mounting orientations is provided.
- a air dryer manifold is secured to an air dryer canister with a bracket located therebetween.
- orientation pegs located adjacent to the sealing surface of the air dryer manifold and are received by a set corresponding indented regions located in a cut away region of the mounting bracket.
- Another aspect of the present invention is a method of mounting an air dryer to a vehicle.
- a mounting bracket having a recess therein is placed over a protrusion on an air dryer manifold.
- the mounting bracket is rotated to a desired mounting orientation and secured into such orientation by a set of orientation pegs located adjacent to the sealing surface of the air dryer manifold.
- An air dryer canister is then fastened to the air dryer manifold protrusion, sealing the mounting bracket therebewteen.
- Figure 1 is a perspective view of an air dryer incorporating a desiccant canister and a mounting bracket.
- Figure 2 is an exploded view of an air dryer incorporating a desiccant canister and a mounting bracket.
- Figure 3 is a perspective view of a mounting bracket.
- Figure 4 is a perspective view of an air dryer of the present invention.
- Figure 5 is a perspective view of an air dryer of the present invention wherein the sealing surface of the air dryer is shown.
- an air dryer assembly generally referenced as 10, includes an air dyer canister 20, a mounting bracket 30, and an air dryer manifold 40.
- the air dryer canister 20 is a conventional canister with a set of threads running through an opening on the underside of the cartridge that receives a set of mating threads 42 protruding from the center of the air dryer manifold 40.
- the threads 42 are between 36 mm and 50 mm.
- the threads 42 are 41 mm, while in another embodiment, the threads are 42 mm.
- an adapter can be used to make the canister 20 with 50 mm threads 42 adapt to 39mm standard threads, for example.
- the air dryer manifold 40 can have any number of inlet and outlet ports 45, four such ports are shown in Figure 2.
- the air dryer manifold 40 includes a purge valve 50, a check valve 54, a safety release valve 58, or some combination thereof.
- the air dryer manifold 40 can be made entirely from plastic or it can be made from plastic with metallic inserts. Examples of the plastic that can be used to make the air dryer manifold 40 include Nylon 6, Delrin or accetel.
- the mounting bracket 30, is fastened to a vehicle frame in the desired location.
- the mounting bracket 30 is formed from stamped steel and is bolted to the frame through mounting holes 60 located on the side surface 61 of the mounting bracket 30.
- the mounting bracket 30 has a cut out portion 64 along the top surface 65 that receives the protruding threads 42 from the air dyer manifold 40.
- the side surface 61 and the top surface 65 are connected to form an approximate right angle. However, one skilled in the art should appreciate that the angle may be more or less than 90°, depending on the desired mounting orientation of the air dryer assembly 10.
- the cut out portion 64 contains a number of indented portions 66 for receiving orientation pegs 69 located adjacent to the sealing surface 70 of the air dyer manifold 40. Each of the orientation pegs 69 are secured against a corresponding indented portion 66, thereby defining and securing the rotative orientation of the mounting bracket 30 relative to the air dryer manifold 40.
- the orientation pegs 69 and corresponding indented portions 66 of the mounting bracket 30 are uniformly positioned about the cut out portion 64 of the mounting bracket 30, the air dryer manifold 40 can to be oriented in a plurality of rotative positions with respect to the mounting bracket 30.
- the ability to rotate the mounting bracket 30 relative to the air dryer manifold 40 permits the inlet and outlet ports 45 to be positioned in a plurality of positions, thereby expanding the possible mounting locations for the air dryer assembly 10. Since the preferred positioning of the air dryer assembly 10 is often dependent upon the vehicle manufacture, it is desirable to allow for a plurality of mounting orientations for the air dryer assembly 10.
- the cut out portion 64 is provided with eight uniformly-spaced indented portions 66, thereby defining an octagonal cut out portion.
- the air dryer manifold 40 can be secured to the mounting bracket 30 in eight different orientations, each separated by 45 degrees.
- the number of orientation pegs 69 located on the sealing surface 70 of the air dyer manifold 40, and the number of corresponding indented portions 66, may vary depending on the number of mounting orientations that are desired. Additionally, it should be appreciated that the mounting bracket 30 could have the orientation pegs 69 located on the bottom side 72 that are received in uniformly spaced holes in the sealing surface 70.
- the sealing surface 70 of the air dyer manifold 40 is preferably substantially flat with a recess 75 that accepts a seal (not shown) therein.
- the air dryer canister 20 has a recess to accept a seal along the sealing surface 74.
- the cut out portion 64 of the mounting bracket 30 is slipped over the protruding threads 42 of the air diyer manifold 40 such that the orientation pegs 69 located on the manifold sealing surface 70 are fit into the corresponding indented portions 66 of the cut out portion 64 to provide to desired rotative orientation of the air dryer manifold 40 to the valve mounting bracket 30.
- the air dyer canister 20 is then threaded onto the protruding threads 42 of the air dryer manifold 40.
- the mounting bracket 30 is clamped between the sealing surfaces 70 and 74 of the manifold and canister, respectively.
- the seals located along the sealing surfaces 70 and 74 compress on the mounting bracket 30 and form an air tight seal.
