Hydraulic pump drive assembly and rotary machine fixture

A rotary machine fixture to couple a first rotary machine to a second rotary machine and to fix the first rotary machine and the second rotary machine to a work vehicle, the fixture comprising:

• a first rotary machine interface configured for mounting the first rotary machine,
• a second rotary machine interface configured for mounting the second rotary machine;
• a work vehicle interface configured for mounting the fixture to the work vehicle such that the first rotary machine and the second rotary machine are rigidly fixed to the work vehicle through the work vehicle interface;
• a cover portion disposed axially between the first rotary machine interface and the second rotary machine interface and defining an internal coupling area configured to accommodate a coupling to couple the first rotary machine to the second rotary machine;
• wherein the first rotary machine interface is configured such that the first rotary machine is rigidly fixed to the fixture only through the first rotary machine interface;
• and
• wherein the first rotary machine interface is disposed at a first fixture side, and wherein the second rotary machine interface is disposed at a second fixture side opposite from the first fixture side.

A hydraulic pump drive assembly to supply hydraulic fluid for a work vehicle, the assembly comprising:

• an electric machine configured to convert electrical energy from an electrical supply line to rotary motion;
• a hydraulic pump operably coupled to the electric machine and configured to circulate the hydraulic fluid through a hydraulic supply line from the rotary motion of the electric machine;
• and
• a fixture having a first rotary machine interface configured to mount the electric machine to the fixture, a second rotary machine interface configured to mount the hydraulic pump to the fixture, and a work vehicle interface configured to mount the fixture to the work vehicle such that the hydraulic pump and the electric machine are fixed to the work vehicle through the fixture;
• wherein the hydraulic pump and the electric machine are rigidly fixed to the work vehicle only by the fixture.
