Systems for a drive unit

A master drive unit (MDU) of an off-highway vehicle, comprising:

• a housing containing a gear reduction set, a hypoid pinion, and a hypoid gear arranged on an output shaft coupled to a wheel, wherein the housing comprises a housing projection having a support end to which a cap is coupled;
• wherein the hypoid pinion is supported by a first bearing, a second bearing, and a third bearing;
• wherein the third bearing is arranged between the cap and the support end;
• and
• wherein the third bearing supports an end of the hypoid pinion proximal to the output shaft.

A housing for a master drive unit (MDU), comprising:

• a housing projection comprising a first linear portion supported by a housing support, a bend extending from the first linear portion into a space between surfaces of the housing, and a second linear portion extending from the bend and coupled to a support end;
• wherein the second linear portion is normal to the first linear portion;
• wherein a triangular brace is in face-sharing contact with each of the first linear portion, the bend, and the second linear portion;
• wherein a bearing is arranged between the support end and a cap and receives an extreme end of a hypoid pinion supported by a plurality of bearings arranged in a bore of the housing, the plurality of bearings including the bearing and at least two further bearings;
• wherein the support end and the cap each comprise a U-shape including a body from which a first arm and a second arm extend, the body coupled to the first arm at a first extreme end and coupled to the second arm at a second extreme end opposite the first extreme end;
• wherein the body of the cap includes a first 90-degree corner at the first extreme end of the cap and a second 90-degree corner at the second extreme end of the cap;
• and
• wherein the body of the support end includes a third 90-degree corner at the first extreme end of the support end and a machined corner comprising a curvature at the second extreme end of the support end.
