Abstract
An example mechanical transmission assembly receives an input rotating at a first rotational speed and provides an output rotating at a second rotational speed. The mechanical transmission selectively adjusts the second rotational speed. The input is provided by a prime mover. The output is provided to a hydraulic pump assembly that rotatably drives a motor-generator.
Claims22
A mechanical transmission assembly, comprising:
- a mechanical transmission that receives an input rotating at a first rotational speed and provides an output rotating at a second rotational speed, the mechanical transmission selectively adjusting the second rotational speed, wherein the input is provided by a prime mover, and the output is provided to a hydraulic pump assembly that rotatably drives a motor-generator.
A prime mover and motor-generator gearing arrangement comprising:
- a hydro-mechanical transmission having differential assembly and a hydraulic pump;
- a motor-generator rotatably driven by the hydro-mechanical transmission;
- and
- a mechanical transmission rotatably driven by a prime mover at a first rotational speed, the mechanical transmission selectively adjustable to rotatably drive the hydraulic pump at the first rotational speed or a second rotational speed different than the first rotational speed.

A method of driving a motor-generator with a prime mover, comprising:
- driving a mechanical transmission with an input from a prime mover, the input rotating at a first rotational speed;
- driving a hydraulic pump with a first output from the mechanical transmission, the first output rotating at a second rotational speed;
- driving the motor-generator with a second output from the hydraulic pump;
- and
- selectively adjusting the mechanical transmission so that the first rotational speed is different than the second rotational speed.
