A two stage hydrodynamic and planetary split torque transmission having a first stage of a hydraulic torque converter and a plurality of planetary gearsets and an extension of a driving shaft transmitting hydraulic and direct drive power to a second stage of a planetary split torque transmission mechanism beyond. The torque converter supplies hydraulic power to the reaction members of the first stage gearsets while the driving shaft supplies power directly to the input member of the first gearse...

These two-speed accessory drive transmissions have spring-loaded centrifugal weights and a planetary friction unit including inner and outer ring members and intermediate ball planets. In one embodiment, the centrifugal weights are urged into frictional drive contact with the planetary carrier during low engine speeds for driving various engine accessories operatively connected to the outer ring member in overdrive. A one-way clutch is located between and connects the input pulley hub and the ou...

A multispeed reversible transmission has a pair of countershafts that are interconnected for counter rotation and a plurality of gear trains for selectively connecting the countershafts to drive the output shaft at various speed ratios. A pair of input clutches are separately engageable to drive the countershafts in either of the two counter rotative directions and a splitter clutch is provided to drive these shafts in one counter direction at a speed ratio lower than that at which they are driv...

An overdrive transmission adapted to be coupled as an auxiliary transmission to a conventional change speed transmission of an automobile and comprising planetary gearing having a planet gear carrier connected to and driven by the output shaft of the conventional transmission, a ring gear engaging the planet gears and connected to a tailshift driving the automobile wheels, and a sun gear engaging the planet gears and held by a friction brake to provide the overdrive speed ratio. A double-acting ...

An automotive transmission is disclosed having first, second and third serially connected housings enclosing an engine driven torque converter, a wheel driving differential gear unit, and a planetary gear set in the respective housings. Input and output shafts project from opposite ends of the planetary gear set with the former connected to the torque converter and the latter connected to a reversing gear set. A further shaft connects the differential gear unit with the reversing gear unit. The ...

A transmission including a die cast transmission housing which is readily convertible for use with three-, four-, or five-speed, sliding gear, fully synchronized transmission assemblies, which assemblies may be accomplished on the motor vehicle, thereby eliminating the need for separate transmission assembly facilities, and, when used as a five-speed transmission, including a novel first and reverse duplex gear arrangement in the rear extension housing.

A fully synchronized four-forward-speed transmission with a reverse gear in an extension housing. The reverse gear is coupled to a constantly driven countershaft by a slideable reverse idler member. An interlock device including two levers having notches in the ends thereof into which pins are movable is also provided.

Manual transmission having clutching and synchronizing assemblies using elongated spring means biasing energizing pins radially outwardly.

A continuously variable transmission including a prime mover driven-input shaft connected by a first transfer drive to drive two spaced toric transmission units which are connected by a second transfer drive combining the outputs from both units to drive a fluid torque converter driving the output shaft. A chain and sprocket transfer drive is connected intermediate the two toric units in one transmission for transferring the combined output from the two toric units to the fluid torque converter ...

A combined fixed ratio planetary traction-drive and toric roller transmission, including a fluid torque converter wherein, in one embodiment, the power input is split at the impeller, with a portion thereof being directed through the planetary drive to overdrive the input race of the toric roller section, thereby reducing torque into the toric section and, consequently, reducing the size requirements of the toric section. The output from the output race is directed to a stator having no overrunn...
