MULTI-MODE POWER TRAINS

摘要

A power train and related vehicle are described for multi-mode power transmission. A first continuously variable power source (“CVP”) may convert rotational power received by the engine for transmission to a second CVP. A variator assembly may receive rotational power from the second CVP at a first input and directly from the engine at a second input. A control assembly may include one or more output components and a plurality of clutch devices arranged between the one or more output components and the variator assembly and engine. In a first state of the control assembly, the plurality of clutch devices may collectively provide direct power transmission between the engine and the one or more output components. In a second state of the control assembly, the plurality of clutches may collectively provide power transmission between the variator and the one or more output components.

1. A power train for a vehicle including an engine, the power train comprising:
a variator assembly configured to receive rotational power directly from the engine at a first input component of the variator assembly; a first continuously variable power source configured to receive rotational power from the engine and convert the received rotational power to a different form; a second continuously variable power source configured to receive the converted power from the first continuously variable power source, convert the received converted power to rotational power, and provide rotational power to a second input component of the variator assembly; and a control assembly with one or more output components and a plurality of clutch devices, each clutch device arranged between the one or more output components and at least one of the variator assembly and the engine, the control assembly configured to receive power from the variator assembly and the engine and to transmit the received power to the one or more output components via at least one of the plurality of clutch devices; wherein, in a first state of the control assembly, the plurality of clutch devices collectively provides direct transmission of power between the engine and the one or more output components; and wherein, in a second state of the control assembly, the plurality of clutch devices collectively transmits to the one or more output components power that is received, via the variator assembly, from both the engine and the second continuously variable power source.
