Abstract: A counter gear section including its supporting device is constituted as a sub assembly. The sub assembly is formed by setting a bearing unit on the counter gear, and the assembly is inserted in the inner surface of a supporting wall of the case and is held and fixed by a brim and a snap ring. Further, splines are formed on a mating surface and an elongated section of an outer race. A one-way clutch is installed on the elongated section.

Abstract: A chainless drive for pedal powered tricycles features a pedal drive shaft located on the axis of the driving wheel and a five speed planetary transmission mounted concentric with the drive shaft and housed within the hub of the wheel. The transmission drives the wheel with a torque which is a multiple of the pedal torque for the two lowest speeds, provides a direct drive for the third speed, and drives the wheel at a multiple of the pedal speed for the two highest speeds. When used as a torque multiplier in the two low speeds, the transmission can drive the wheel either forward or in reverse depending on the direction the pedals are rotated, but permits coasting with the pedals stopped in speeds three, four, and five. A tricycle using this invention with a bin or flatbed should be useful in the factory or on the farm for the transport of parts or produce, or useful as a two passenger taxi with a seat assembly.

Abstract: An automatic transmission comprising a single planetary gear unit and a dual planetary gear unit has an output member located in its center so that the output member encloses an input shaft.In the case of a three speed automatic transmission mechanism, a first clutch located around a ring gear of the single planetary gear unit connects the input shaft to this ring gear.In the case of a four speed automatic transmission mechanism, a third clutch which actuates overdrive is additionally located axially outside the first clutch for connecting the input member to a ring gear of the dual planetary gear unit.A sun gear common to both planetary units is connected to the input shaft by a second clutch. This clutch has a drum portion upon which a band may act to brake the sun gear.

Abstract: Automatic transmission including a main-transmission-mechanism consisting of two planetary gear units (three speed or four speed transmission mechanism for example) and a sub-transmission-mechanism consisting of one planetary gear unit (underdrive mechanism, for example). One speed and two speed for the whole transmission are obtained, with a low speed stage of the main-transmission-mechanism lower than two speed, by shifting the main-transmission-mechanism to one and two speed, respectively, while the sub-transmission-mechanism is kept at low speed (underdrive). And three speed for the whole transmission is obtained by shifting the sub-transmission-mechanism to high speed (direct coupling) while the main-transmission-mechanism is left at the two speed state. Further, four speed or five speed for the whole is obtained by shifting the main-transmission-mechanism to three speed or, if it is of four speed type, to four speed, respectively, while the sub-transmission-mechanism is kept at the high speed state.
