Abstract
A driveline product including first and second inputs having input rotational axes, first and second outputs having output rotational axes, a transfer coupling between at least one of the input rotational axes and at least one of the output rotational axes, and at least two selective couplings operatively coupled between the inputs and the outputs for operation selective between at least two drives powered by at least one of two prime movers.
Claims27
A driveline product comprising:
- a first input to receive first prime mover torque and having a first input rotational axis;
- a second input to receive second prime mover torque having a second input rotational axis, wherein the first and second input rotational axes are laterally spaced apart from one another;
- a first output to transmit first driveline torque and having a first output rotational axis;
- a second output to transmit second driveline torque and having a second output rotational axis, wherein the first and second output rotational axes are laterally spaced apart from one another;
- a transfer coupling to couple at least one of the input rotational axes to at least one of the output rotational axes, wherein the transfer coupling includes a cross-axis transfer coupling to couple at least one of the input rotational axes to at least one of the output rotational axes, wherein the cross-axis transfer coupling includes a first sprocket selectively coupled to the first output and a second sprocket fixedly coupled to the second input and an endless torque transmitting element coupled to the first and second sprockets;
- a first selective coupling to couple the first input to the first output;
- and
- a second selective coupling to couple the second input to the second output.
