20100227726 | TRANSMISSION - In a transmission including a multiple planetary mechanism into which power from a driving source is inputted through an input shaft, clutches are provided respectively for three components among a plurality of components included in the multiple planetary mechanism and are respectively disposed and capable of switching between connection and disconnection of transmission of power between the input shaft and the three components. Brakes are respectively provided between a transmission case and components among the plurality of components. The brakes are configured to make the components stationary relative to the transmission case. Two transmission mechanisms different from each other in speed reduction ratio are provided between an output shaft, which is parallel with the input shaft, and two components among the plurality of components. The two transmission mechanisms are provided in such a manner as to be capable of selectively switching transmission of the power to the output shaft side. Accordingly, it is possible to provide a transmission whose controllability of transmission is enhanced, and whose efficiency is improved by reducing the friction. | 09-09-2010 |
20100298086 | AUTOMATIC TRANSMISSION - Provided is an automatic transmission capable of reducing friction loss. The automatic transmission is provided with an input shaft ( | 11-25-2010 |
20130040773 | HYBRID VEHICLE DRIVING SYSTEM - In a driving apparatus for a hybrid vehicle having an internal combustion engine and first and second electric rotating machines, it is configured to have a speed increasing mechanism that increases speed of an output of the engine inputted through an input shaft and transmits it to the first electric rotating machine; a speed reducing mechanism that reduces speed of an output of the second electric rotating machine and transmits it to an output shaft; a first clutch adapted to connect and disconnect a first driving force transmission path coupling the speed increasing mechanism and the output shaft; and a second clutch adapted to connect and disconnect a second driving force transmission path coupling the engine and the output shaft. | 02-14-2013 |
20130210571 | AUTOMATIC TRANSMISSION - Provided is an automatic transmission capable of reducing friction loss. The automatic transmission is provided with an input shaft ( | 08-15-2013 |
20140287866 | AUTOMATIC TRANSMISSION - In an automatic transmission, a connection member which connects a carrier of a planetary gear mechanism PGSa to a clutch hub of a clutch is made to abut on the carrier of the planetary gear mechanism PGSa in an abutting portion, a thrust bearing T | 09-25-2014 |
20140287867 | AUTOMATIC TRANSMISSION - An automatic transmission includes a thrust bearing A disposed between a third sun gear of a third planetary gear mechanism and a second sun gear of a second planetary gear mechanism. Accordingly, transmitting a thrust load acting on the second sun gear of the second planetary gear mechanism from the thrust bearing to an input shaft via the third sun gear of the third planetary gear mechanism can avoid, as much as possible, a case where the thrust load is transmitted from the third planetary gear mechanism to the input shaft via a fourth planetary gear mechanism, and reduce friction loss of multiple thrust bearings interposed among elements or the like of the third planetary gear mechanism and the fourth planetary gear mechanism. | 09-25-2014 |
