Abstract

A mounting arrangement is provided for mounting the air cleaner for an internal combustion engine in a vehicle. The air cleaner generally includes a casing having air inlet and outlet openings and an open side, a pot-shaped housing containing a filter element and having an open side selectively attachable to the open side of the casing. The mounting arrangement provides two substantially parallel and horizontal rods upon which the air cleaner can be placed. The air cleaner can be held to the rods by a variety of techniques, including hooks and guide rings. The mounting structure allows the housing to be detached and slid away from the casing for cleaning or replacement of the filter element, then be accurately realigned with the casing so that an accurate seal can be engaged.

Claims

1. A mounting arrangement for an air cleaner of an internal combustion engine of a vehicle, where the air cleaner has:

(i) a casing open on one side which is provided with at least one of a raw air inlet and a clean air outlet; and

(ii) a pot-shaped housing open on one side, and enclosing a filter element; and

(iii) attachment means for selectively attaching the open side of the housing to the open side of the casing;

characterized in that at least two generally horizontal guide rods are mounted to the vehicle structure substantially parallel to each other such that the housing and the casing can be placed on the guide rods in axial alignment with each other and such that at least one of the housing and the casing can be moved axially with respect to the other of the housing and the casing into a position in which the attachment means can attach the housing and the casing together.

2. The mounting arrangement of claim 1, characterized in that the housing and the casing are generally cylindrical.

3. The mounting arrangement of claim 1, further characterized in that guide means are mounted to at least one of said housing and said casing, said guide means being supported on said guide rods.

4. The mounting arrangement of claim 3, further characterized in that said guide means comprises concentric rings of equal outside diameters mounted on the outside of said at least one housing and casing, where said outside diameters are larger than the distance between said two guide rods.

5. The mounting arrangement of claim 3 further characterized in that at least one of said guide rods has a threaded section on at least one end thereof to which fastener means can be applied to fasten said air cleaner to a component of the vehicle structure.

6. The mounting arrangement of claim 5, further characterized in that said at least one threaded guide rod extends through the component of the vehicle structure to which it is mounted, and in that said fastener means comprises two nuts threaded onto said threaded section to clamp said component and at least a portion of said guide means on said casing therebetween.

7. The mounting arrangement of claim 3, further characterized in that said guide means comprises at least one hook-shaped projection mounted to said at least one element, the opening of said hook-shaped projection opening downward and engaging the associated guide rod from above when the air cleaner is assembled.

8. The mounting arrangement of claim 7, further characterized in that said at least one hook-shaped projection is mounted to said housing and the downward-directed opening thereof is provided with a cylindrical recess on the side facing the casing that is concentric with the associated guide rod when the air cleaner is assembled and in that a rubber cylinder is mounted to the associated guide rod and engages said recess when the air cleaner is closed and assembled.

9. The mounting arrangement of claim 1, further characterized in that said attachment means comprises a bayonet lock.

10. The mounting arrangement of claim 9, further characterized in that said bayonet lock comprises bayonet cams mounted around the open side of said housing and a bayonet ring rotatably mounted around the open side of said casing which can be rotated to interact with said cams in the manner of a bayonet connection.

11. The mounting arrangement of claim 9, further characterized in that said bayonet lock comprises bayonet cams mounted around the open side of said casing and said housing, and wherein said housing can be rotated to engage said cams in the manner of a bayonet connection.

12. The mounting arrangement of claim 11, further characterized in that at least one hook-shaped projection is mounted to said housing to selectively engage a corresponding one of said guide rods and extends to such a length that said guide rod is located in the engagement region of the hook-shaped projection during rotation of the housing to engage the lock.

13. The mounting arrangement of claim 12, further characterized in that said corresponding guide rod is provided with rubber sleeves in the region thereof which will be engaged by the hook-shaped projection.
