Abstract
A transmission including first and second input shafts rotatable about a first axis of rotation; at least one output shaft rotatable about at least one second axis of rotation, the at least one second axis of rotation non-collinear with the first axis of rotation; a plurality of lay shafts; a plurality of gears; and a plurality of half synchronizer clutches arranged to non-rotatably connect at least a portion of the plurality of gears to the plurality of lay shafts to transmit respective torque from the first and second input shafts to the at least one output shaft and disconnect the at least a portion of the plurality of gears from the plurality of lay shafts.
Claims20
A transmission, comprising:
- first and second input shafts rotatable about a first axis of rotation;
- at least one output shaft rotatable about at least one second axis of rotation, the at least one second axis of rotation non-collinear with the first axis of rotation;
- a plurality of lay shafts;
- a plurality of gears;
- and,
- a plurality of half synchronizer clutches arranged to:
- non-rotatably connect at least a portion of the plurality of gears to the plurality of lay shafts to transmit respective torque from the first and second input shafts to the at least one output shaft;
- and,
- disconnect the at least a portion of the plurality of gears from the plurality of lay shafts, wherein:
- the at least one output shaft includes:
- a first longitudinal end:
- extending past the plurality of gears in a first direction parallel to the at least one second axis of rotation;
- and,
- arranged to transmit torque from the transmission to at least one first component located outside of the transmission;
- a second longitudinal end:
- extending past the plurality of gears in a second direction, opposite the first direction;
- and,
- arranged to transmit torque from the transmission to at least one second component, different from the at least one first component, located outside of the transmission.
A transmission, comprising:
- a casing;
- a first input shaft rotatable about a first axis of rotation;
- a second input shaft, different from the first input shaft,
- a plurality of lay shafts located within the casing;
- a plurality of gears located within the casing;
- a plurality of half synchronizer clutches located within the casing and arranged to:
- non-rotatably connect at least a portion of the plurality of gears to the plurality of lay shafts;
- and,
- disconnect the at least a portion of the plurality of gears from the plurality of lay shafts;
- first and second output shafts;
- and,
- a differential gear assembly located within the casing and arranged to transmit respective torque from the first or second input shafts to the first and second output shafts.
A transmission, comprising:
- a casing;
- first and second input shafts rotatable about a first axis of rotation;
- first and second output shafts;
- a differential gear assembly wholly located within the casing and arranged to transmit respective torque from the first and second input shafts to the first and second output shafts;
- first and second planetary gears sets arranged to transmit the respective torque to the differential gear assembly;
- a plurality of lay shafts located within the casing and including:
- a first lay shaft arranged to transmit the respective torque to the first planetary gears set;
- and,
- a second lay shaft arranged to transmit the respective torque to the second planetary gears set;
- and,
- a plurality of half synchronizer clutches located within the casing and arranged to:
- non-rotatably connect at least a portion of the plurality of gears to the plurality of lay shafts to transmit the respective torque to the plurality of lay shafts;
- and,
- disconnect the at least a portion of the plurality of gears from the plurality of lay shafts.
