    Abstract: A speed change mechanism in which the gear ratio is selected by changing the direction of rotation of the power input includes first and second planetary gear sets enclosed within a hub shell. A DC electric motor is coupled to the sun gears of both gear sets and drives them simultaneously in the same rotary direction. In one of the gear sets the carrier arm is fixed and the ring gear is the output and in the other gear set the ring gear is fixed and the carrier arm is the output. A first one-way clutch transmits drive from an output of the first gear set to the hub shell and second one-way clutch transmits drive from an output of the second gear set to the hub shell, both clutches operating in the same direction. The outputs of the gear sets are driven in opposite rotary directions so that drive is transmitted to the hub shell either through the first gear set or the second gear set depending on the direction of rotation of the power input to provide two different gear ratios.

    Abstract: An actuator assembly for selectively actuating a clutch includes a first actuator ring that is moveable between a first axial position and a second axial position along a rotational axis of the clutch, and a second actuator ring that is slidably received within the first actuator ring, and that is moveable between a third axial position and a fourth axial position by the first actuator ring. The first actuator ring receives a first actuation force, and when in the second axial position, transfers the first actuation force to the second actuator ring. The second actuator ring selectively receives the first actuation force and a second actuation force, and when in the fourth axial position, transfers one of the first and second actuation forces to the clutch. The actuator assembly is included with a transmission and actuates a clutch that provides an input to a planetary gear set of the transmission.

    Abstract: An automatic transmission includes a first planetary gear set; a second planetary gear set; a third planetary gear set; an input shaft; an output shaft; and five friction elements. A first ring gear is constantly locked. A third carrier is connected with a second ring gear to define a rotating member.

The five friction elements include a first friction element adapted to selectively connect a first carrier with a third ring gear; a second friction element adapted to selectively connect a first sun gear with the second carrier; a third friction element adapted to selectively connect the first sun gear with a second sun gear; a fourth friction element adapted to selectively connect the first carrier with the second carrier; and a fifth friction element adapted to selectively connect the first carrier with the second sun gear. Each of at least seven forward speed-ratios and one reverse speed-ratio is achieved by an engaged state of two friction elements selected from the five friction elements.

    Abstract: A transmission mechanism includes a first gear unit having an axially-movable ring gear and a second gear unit having an axially-movable fixing ring. The fixing ring includes first and second protrusions on two sides, respectively. When the ring gear moves, the first inner teeth and the outer teeth of the second planet gear disk are engaged with each other or disengaged from each other. When the fixing ring moves, the first protrusions and the first positioning ridges are engaged with each other or disengaged from each other, or the second protrusions and the second positioning ridges are engaged with each other or disengaged from each other. By the different combinations of the statuses due to movement of the ring gear and the fixing ring, the input speed from the motor gear is transferred into four different speeds which is output from an output shaft.

    Abstract: An automatic transmission includes four planetary gear sets, a plurality of friction and synchronizing clutches and two chain drive assemblies. Input torque is provided to four clutches which selectively provide torque to one element of a compound assembly comprising first and second planetary assemblies. The second planetary assembly includes only a sun gear and a planet carrier including elongate, stepped pinion gears which extend into the planet carrier of the adjacent first planetary assembly. The sun and ring gears of the first planetary assembly drive respective chain drive sprockets. A pair of chains transfer torque to respective driven chain sprockets. The chain driven by the first planetary assembly sun gear drives a third planetary assembly sun gear. The chain driven by the first planetary assembly ring gear drives a fourth planetary assembly sun gear. The transmission output is connected to the planet carriers of the third and fourth planetary assemblies.
