Abstract

A transmission side cover assembly includes a transmission side cover carrying completely there on one or more filters and/or a cooler. Fluid flow channels are formed integrally in the material of the cover and provide fluid flow communication paths to the filters and/or cooler carried by the cover. The filters and/or cooler carried by the cover are accessible externally of the cover, for servicing thereof without removing the cover.

First claim

What is claimed is:

1. A transmission side cover assembly, comprising:
a side cover including formations that are configured to connect with a transmission, said side cover defining a fluid manifold;
one or both of at least one filter or a cooler retained by said side cover;
at least one fluid channel integrally formed in said side cover establishing fluid flow communication to said one or both of said at least one filter or said cooler;
a filter element cap connected to said side cover and in fluid flow communication with said fluid manifold; and
a filter element disposed in said filter element cap;
said side cover configured to provide external accessibility to said one or both of said at least one filter or said cooler when said side cover is connected to said transmission,
wherein said one or both of said at least one filter or said cooler are configured to be removed from said side cover without removing said side cover from said transmission.

2. The transmission side cover assembly of claim 1 , said side cover defining a filter compartment having an inlet and an outlet;
said at least one filter including a transmission fluid filter body disposed in said filter compartment; and
said at least one fluid channel including filter compartment fluid channels integrally formed in said side cover establishing fluid flow communication to said filter compartment inlet and from said filter compartment outlet.

3. The transmission side cover assembly of claim 2 , said transmission fluid filter body including a first filter element, a second filter element and a fluid barrier between said first and second filter elements.

4. The transmission side cover assembly of claim 1 , said at least one filter including a first filter retained by said side cover and said at least one fluid channel having first filter fluid channels connected thereto in fluid flow communication, said first filter fluid channels being integral with said side cover.

5. The transmission side cover assembly of claim 4 , said at least one filter further including a second filter retained by said side cover and said at least one fluid channel having second filter fluid channels connected thereto in fluid flow communication, said second filter fluid channels being integral with said side cover.

6. The transmission side cover assembly of claim 5 , further including said cooler attached to said side cover, and fluid channels to and from said cooler integral in said side cover.

7. The transmission side cover assembly of claim 5 , one of said first filter and said second filter including a filter compartment formed in said side cover, and a filter body contained in said filter compartment.

8. The transmission side cover assembly of claim 7 , said filter body including a first filter element, a second filter element and a fluid barrier disposed between said first and second filter elements.

9. The transmission side cover assembly of claim 1 , said at least one filter including a first filter element secured to said side cover by threaded fasteners.

10. The transmission side cover assembly of claim 9 , said side cover defining a suction side filter compartment, and said first filter element being disposed in said suction side filter compartment.

11. The transmission side cover assembly of claim 1 , including:
a suction side filter compartment formed in said side cover;
said at least one filter including a suction side filter body disposed in said suction side filter compartment;
said cooler connected to said side cover; and
said at least one fluid channel including fluid channels integrally formed in said side cover establishing fluid flow communication to said suction side filter compartment, said pressure side filter, and said cooler.

12. The transmission side cover assembly of claim 11 , said side cover defining flange through holes for receiving torque limiters and fasteners connecting said transmission side cover assembly to said transmission.

13. The transmission side cover assembly of claim 11 , said suction side filter body including a mechanical pump suction element, an electric pump suction element and a fluid flow barrier between said suction elements.

14. The transmission side cover assembly of claim 13 , said suction side filter compartment defining an internal slot, and said fluid flow barrier being disposed in said internal slot.

15. The transmission side cover assembly of claim 13 , including separate fluid inlet and outlet paths for said mechanical pump suction element and said electric pump suction element.

16. A transmission side cover assembly, comprising:
a side cover including formations that are configured to connect with a transmission;
one or both of at least one filter or a cooler retained by said side cover, said at least one filter including a first filter retained by said side cover and a second filter retained by said side cover;
at least one fluid channel integrally formed in said cover establishing fluid flow communication to said one or both of said at least one filter or said cooler, said at least one fluid channel having first filter fluid channels and second filter fluid channels connected thereto in fluid flow communication, said first filter fluid channels and said second filter fluid channels being integral with said side cover,
said side cover configured to provide external accessibility to said one or both of said at least one filter or said cooler when said side cover is connected to said transmission,
wherein said one or both of said at least one filter or said cooler are configured to be removed from said side cover without removing said side cover from said transmission.

17. The transmission side cover assembly of claim 16 , further including said cooler attached to said side cover, and fluid channels to and from said cooler integral in said side cover.

18. The transmission side cover assembly of claim 16 , one of said first filter and said second filter including a filter compartment formed in said side cover, and a filter body contained in said filter compartment.

19. The transmission side cover assembly of claim 18 , said filter body including a first filter element, a second filter element, and a fluid barrier disposed between said first and second filter elements.

20. A transmission side cover assembly, comprising:
a side cover including formations that are configured to connect with a transmission, said side cover defining a filter compartment having an inlet and an outlet;
one or both of at least one filter or a cooler retained by said side cover, said at least one filter including a transmission fluid filter body disposed in said filter compartment, said transmission fluid filter body including a first filter element, a second filter element, and a fluid barrier between said first and second filter elements ;
at least one fluid channel integrally formed in said cover establishing fluid flow communication to said one or both of said at least one filter or said cooler, said at least one fluid channel including filter compartment fluid channels integrally formed in said side cover establishing fluid flow communication to said filter compartment inlet and from said filter compartment outlet,
said side cover configured to provide external accessibility to said one or both of said at least one filter or said cooler when said side cover is connected to said transmission,
wherein said one or both of said at least one filter or said cooler are configured to be removed from said side cover without removing
