Abstract
A vehicle transmission using a gearset. Multi-mode clutches selectively couple components of the gearset. The transmission operates in and shifts between a first forward gear and a second forward gear using a change in input rotation. An electric motor coupled to the input may be used to change the input rotation direction.
Claims19
A transmission comprising:
- an input;
- a gearset having a first forward speed and a second forward speed;
- the input movable in a first direction and a second direction wherein moving the input in the first direction operates the gearset at the first forward speed and moving the input in the second direction operates the gearset at the second forward speed;
- and
- a first clutch and a second clutch, the first clutch selectively couples a component of the gearset directly to a stationary member, and the second clutch selectively couples the component of the gearset directly to the input.

A vehicle drive system comprising:
- a motor operable in a first direction and a second direction;
- a transmission including a housing, an input, and an output, the input connected to the motor;
- a gearset connected to the input and the output;
- a first clutch selectively coupling a component of the gearset directly to the housing;
- a second clutch selectively coupling the component of the gearset directly to the input or the output;
- and
- the gearset has a first forward speed and a second forward speed, the gearset operating in the first forward speed when the motor operates in the first direction of rotation and operates in the second forward speed when the motor operates in the second direction of rotation.
4 more elements
A transmission comprising:
- an input rotatable in a first direction and a second direction;
- an output rotatable in at least one of the first direction and the second direction;
- a housing, the housing stationary relative to the input and the output;
- a planetary gearset including a planet gear, a planet gear carrier, a ring gear, and a sun gear;
- a first clutch selectively coupling the planet gear carrier of the planetary gearset directly to the housing;
- a second clutch selectively coupling the planet gear carrier of the planetary gearset directly to one of the input and the output;
- and
- the transmission operates in a first gear when the input rotates in the first direction and operates in a second gear when the input rotates in the second direction.
