Abstract
A powertrain system is provided that includes a prime mover and a change-gear transmission having an input, at least two gear ratios, and an output. The powertrain system also includes a power shunt configured to route power applied to the transmission by one of the input and the output to the other one of the input and the output. A transmission system and a method for facilitating shifting of a transmission system are also provided.
Claims50
A powertrain system, comprising:
- a prime mover;
- a change-gear transmission including an input, at least two gear ratios, and an output;
- and
- a power shunt configured to route power applied to the transmission by one of the input and the output to the other one of the input and the output.

A powertrain system, comprising:
- a prime mover;
- a change-gear transmission that includes an input, at least two gear ratios and an output;
- a first motor-generator connected to the input and a second motor-generator connected to the output, a first power path between the input and the output of the transmission, the first power path defined by the gear ratios of the transmission;
- and
- a second power path between the input and the output of the transmission, the second power path defined by the first and second motor-generators.

A transmission system, comprising:
- a change-gear transmission including an input, at least two gear ratios, and an output;
- and
- a power shunt configured to route power applied to the transmission by one of the input and the output to the other one of the input and the output.
A method for operating of a transmission, comprising:
- providing a change-gear transmission including an input, at least two gear ratios, and an output;
- and
- shunting power applied to the transmission by one of the input and the output to the other one of the input and the output.
A powertrain system, comprising:
- a change-gear transmission including an input, at least two gear ratios, and an output;
- a prime mover connected to the input and configured to apply power to the transmission;
- and
- a motor-generator connected to the output and adapted to absorb or apply power to the output in conjunction with a corresponding increase or decrease, respectively, in the application of power by the prime mover to the transmission to facilitate a gear ratio change in the transmission.
