Abstract: A change-speed gear system for use in an automatic transmission, which includes a center output shaft, hollow input and intermediate shafts coaxially disposed around the center output shaft, first and second planetary gear mechanisms, first and second selectively actuatable clutches, and first and second selectively actuatable brakes.Sun gears of the two planetary gear mechanisms are secured to the intermediate shaft while the planetary carrier and the ring gear respectively of the first and second planetary gear mechanisms are secured to the output shaft.Driving portions of the two clutches are coupled to the input shaft while drivable portions of the first and second clutches are respectively coupled to the ring gear of the first planetary gear mechanism and to the intermediate shaft. Movable portions of the first and second brakes are respectively coupled to the intermediate shaft and to the planetary carrier of the second planetary gear mechanism. The above arrangement not only provides a change-speed gear system which has three forward-speed gear ratios and one reverse-speed ratio by selective actuation of the clutches and brakes, but also provides a change-speed gear system which allows the automatic transmission to be alternatively used in various types of vehicular drive systems such as front-engine and front-wheel drive and rear-engine and rear-wheel drive.

Abstract: An overdrive device is provided for use in an automatic transmission of the type including a torque converter and a change gear mechanism.The torque converter has a pump impeller obtaining its input from an engine and a turbine runner whose output is applied to a shaft of the change gear mechanism. The overdrive device is disposed between the torque converter and the change gear mechanism and is responsive to the operation of the change gear mechanism. The device includes a planetary gear train, an overdrive brake, and a one-way clutch.During overdrive, when the speed of the shaft of the change gear mechanism exceeds that of the turbine runner, the overdrive brake is actuated to connect the shaft of the change gear mechanism through the planetary gear train to the pump impeller of the torque converter. The device bypasses the turbine runner of the torque converter by a one-way clutch decoupling the shaft of the change gear mechanism. This overdrive device provides for fuel efficiency by eliminating fluid turbulence in the torque converter during this overdrive condition.

Abstract: An overdrive mechanism is provided for use in an automatic transmission of the type including a torque converter and a change gear mechanism. The torque converter has a pump impeller obtaining its input from an engine and a turbine runner whose output is applied to a shaft of the change gear mechanism.The overdrive mechanism is disposed between the torque converter and the change gear mechanism and is responsive to the operation of the change gear mechanism. The overdrive mechanism includes a planetary gear train having a sun gear fixed stationary, a carrier operatively responsive to the pump impeller of the torque converter, and a ring gear operatively connected to the sun gear and carrier so that it at all times has output power of a rotational speed greater than that of the engine. An overdrive clutch is provided that connects the shaft of the change gear mechanism to the pump impeller of the torque converter through the ring gear and planetary gear train to thereby by-pass the turbine runner of the torque converter.This device provides for fuel efficiency by eliminating fluid turbulence in the torque converter during this overdrive condition.
