HYDRAULIC HYBRID POWERTRAIN SYSTEM

摘要

A hydraulic hybrid powertrain system includes a power plant generating a high pressure fluid at an output, at least one drive motor responsive to the high pressure fluid for generating rotary motion at an output, a mode selection means connected to the power plant output and the at least one drive motor for selecting a mode of operation of the at least one drive motor. The system also includes a control means connected to the power plant and the at least one drive motor for controlling operation of the at least one drive motor and a selectively actuated brake means for interrupting a flow of the high pressure fluid to the at least one drive motor.
