An overdrive device for motor vehicle transmissions includes a sun gear, planet pinions and a ring gear in meshing relationship. A one-way clutch having an inner race integrally secured to the sun gear is provided with the outer race of the one-way clutch being spline-coupled to a carrier which rotatably supports the planet pinions. A certain degree of slack or looseness is provided between the carrier and the outer race to permit some relative movement therebetween in the radial direction of the overdrive device.

An automatic transmission includes a gear transmission mechanism including first and second friction mechanisms which are alternatively engaged by alternative supply of first and second pressures thereto when the highest speed stage and the next to highest speed stage are alternatively engaged, and a torque converter including a lockup clutch. A transmission control system includes a pressure control system which controls the gear transmission mechanism by selectively supplying those pressures and possibly others thereto, a lockup clutch control valve which according to its switched position controls the engagement of the lockup clutch and which is switched to its engage position by a control pressure, and a lockup clutch interrupt valve, which selectively transmits the first pressure to the lockup clutch control valve as the control pressure, which is supplied with the second pressure which when present switches it positively to its non communicating condition, and which is also supplied with governor pressure which in the absence of the second pressure switches it to the communicating condition when this governor pressure is higher than a certain value, and otherwise leaves it in the non communicating condition.
摘要:
An automatic transmission with overdrive in which a torque converter, an overdrive gear mechanism and an underdrive gear mechanism are separately segmented and are assembled or fastened together by simple devices, such as bolts. To enable this, the dimensions of these components which are associated with coupling portions thereof, such as inner and outer diameters, are designed for standarization. Accordingly, a torque converter and an underdrive gear mechanism of conventional type may be used requiring little or no modification. Additonally, the components are advantageously arranged with the overdrive gear mechanism positioned between the torque converter and the underdrive gear mechanism. The input shaft of the overdrive gear mechanism is splined to the output end of a shaft for the turbine vanes, and is positioned in axial alignment with the input shaft of the underdrive gear mechanism as well as with the shaft for the turbine vanes.

A gear means of an automatic transmission for automobiles including a planetary gear means and friction engaging means in combination, a carrier of the planetary gear means being integrally combined with one of two relatively rotatable elements of the friction engaging means to provide an integral carrier assembly which in turn provides a planetary assembly by incorporating planetary pinions, wherein a rotary mass unbalance of the planetary assembly due to an asymmetrical arrangement of planetary pinions is compensated for by removing a part of the one of the two relatively rotatable elements forming a part of the carrier assembly.

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.
