Abstract

An improved engine oil pan and transfer case assembly is provided wherein an oil reservoir and a first transfer case housing portion are unitarily combined. The first transfer case housing portion is adapted to combine together with a second transfer case housing portion to form a complete transfer case housing.

Claims (13)

1. A combination engine oil pan and transfer case housing assembly, the combination comprising:

an engine oil pan having a reservoir unitarily formed with a first transfer case housing portion; and

a second transfer case housing portion adapted to be secured to said first transfer case housing portion, wherein said first and second transfer case housing portions combine to form a complete transfer case housing.

2. The oil pan and transfer case housing assembly of claim 1 , wherein

said first transfer case housing portion includes an open-ended hollow semi-cylinder-shaped mating portion, said second transfer case housing portion includes an open-ended hollow cylinder-shaped mating portion, and said mating portion of said first transfer case housing portion mates with said mating portion of said second transfer case housing portion in form-fitting fashion.

3. The one-piece transfer case housing and engine oil pan assembly of claim 1 , wherein

said first transfer case housing portion includes an open-ended hollow semi-cylinder-shaped mating portion, said second transfer case housing includes an open-ended hollow semi-cylinder-shaped mating portion, and said mating portions of said first and second transfer case housing portions combine with each other in a complementary fashion such that their combination forms an open-ended hollow cylinder.

4. The engine oil pan and transfer case housing assembly of claim 3 , wherein each of said open-ended hollow semi-cylinder-shaped mating portion of said second transfer case housing portion and said open-ended hollow semi-cylinder-shaped mating portion of said first transfer case housing portion has a variable radius.

5. The engine oil pan and transfer case assembly according to claim 1 , wherein said first transfer case housing portion and second transfer case portion are bolted together to form a complete housing.

6. A combination engine oil pan and transfer case adapted to be secured to an automotive vehicle, said engine oil pan comprising:

a resevoir portion unitarily formed with a first housing portion; and

said transfer case including;

a second housing portion, wherein said first housing portion of said engine oil pan and said second housing portion of said transfer case are bolted together to define a complete housing provided to retain a set of gears for differentially transferring torque between and input shaft and an output shaft.
