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.
Claims13
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, wherein the mechanical transmission receives the input rotating at the first rotational speed and provides an output rotating at a third rotational speed, the third rotational speed different than the first rotational speed and the second rotational speed.
A mechanical transmission assembly, comprising:
- a mechanical transmission configured to be rotatably driven by a prime mover at a first rotational speed, the mechanical transmission selectively adjustable to provide a rotatable output that drives a hydraulic pump at the first rotational speed or a second rotational speed different than the first rotational speed, wherein the mechanical transmission is further selectively adjustable to rotatably drive the hydraulic pump at a third rotational speed that is different than both the first rotational speed and the second rotational speed.
