Hydraulic-electric drive arrangement for work vehicles
First Claim
1. A hydraulic-electric drive assembly for a work vehicle having a prime mover, comprising:
- a hydraulic pump drive having;
a manifold housing;
a power input interface configured to couple with the prime mover for receiving rotational input power; and
a plurality of power output interfaces coupled to the power input interface to transmit the input power from the prime mover mechanically at a first drive speed;
at least one hydraulic pump mounted to at least one of the power output interfaces to be driven by the input power from the prime mover; and
at least one electric generator coupled to at least one of the power output interfaces to be driven by the input power from the prime mover, the at least one electric generator configured to convert the input power from the prime mover into electric powerwherein the at least one electric generator includes at least one electric machine and at least one gear set coupled to the associated one of the plurality of power output interfaces;
wherein the manifold housing defines a common mounting pad for each of the power output interfaces; and
wherein the at least one hydraulic pump and the at least one gear set each includes a housing defining a common mounting interface of a complementary configuration for mating with the associated mounting pad.

Abstract
A hydraulic-electric drive assembly for a work vehicle has a hydraulic pump drive including a manifold housing, a power input interface configured to couple with a prime mover for receiving rotational input power, and a plurality of power output interfaces coupled to the power input interface to transmit the input power from the prime mover mechanically at a first drive speed. At least one hydraulic pump is mounted to at least one of the power output interfaces to be driven by the input power from the prime mover. At least one electric generator is coupled to at least one of the power output interfaces to be driven by the input power from the prime mover. The at least one electric generator is configured to convert the input power from the prime mover into electric power.
