Abstract
A power train assembly includes an input member drivingly engaged by a power source, at least one output member and at least one gear assembly. The output member is driveably connected to the input member through the gear assembly. A brake assembly is engaged with the output member and a casing is configured to enclose the gear assembly and the brake assembly. The casing includes a main chamber in communication with at least one storage chamber and a reservoir. The storage chamber is adapted to receive a flow of lubrication fluid from the reservoir.
Claims36
A power train assembly comprising:
- an input member drivingly engaged by a power source;
- at least one output member;
- at least one gear assembly, said at least one output member being driveably connected to said input member through said at least one gear assembly;
- a brake assembly operative to modify a speed of said at least one output member;
- and
- a casing configured to enclose said at least one gear assembly and said brake assembly, said casing comprising:
- a main chamber in communication with at least one storage chamber and a reservoir, said at least one storage chamber being adapted to receive a flow of lubrication fluid from said reservoir,
- wherein said brake assembly is adapted to receive said fluid from said at least one storage chamber.
A method for operating a power train assembly, the power train assembly comprising:
- an input member;
- at least one output member;
- at least one gear assembly, said output member being driveably connected to said input member through said at least one gear assembly;
- a brake engagable with the at least one output member and being operative to modify a speed of the output member;
- a fluid reservoir;
- and a casing comprising:
- a main chamber configured to enclose said at least one gear assembly and a storage chamber, the method comprising:
- storing an amount of fluid in the fluid reservoir;
- directing fluid from the reservoir into the storage chamber of the casing;
- and
- causing fluid to be directed from the storage chamber to the at least one brake assembly.
A differential and final drive assembly comprising:
- a driveably engageable drive member;
- at least one output member;
- at least one gear assembly, said output member being driveably connected to said input member through said at least one gear assembly;
- a brake assembly operative to modify a speed of said at least one output member;
- a casing configured to enclose said at least one gear assembly and said brake assembly, said casing comprising:
- a main chamber in communication with at least one storage chamber;
- and
- a reduction gear assembly disposed between said brake assembly and said storage chamber, said reduction gear assembly being structured and arranged with said brake assembly to direct a flow lubrication fluid toward said brake assembly.
A power train assembly comprising:
- an input member drivingly engaged by a power source;
- at least one output member;
- at least one gear assembly, said at least one output member being driveably connected to said input member through said at least one gear assembly;
- a brake assembly operative to modify a speed of said at least one output member;
- a casing configured to enclose said at least one gear assembly and said brake assembly, said casing comprising:
- a main chamber in communication with at least one storage chamber and a reservoir;
- and
- fluid circulation means for directing fluid through said brake assembly to carry away heat generated by said brake assembly., said at least one storage chamber being adapted to receive a flow of lubrication fluid from said reservoir.
