20160025191 | POWERTRAIN FOR AUTOMATIC TRANSMISSION - The present invention relates to a powertrain for an automatic transmission. The powertrain for an automatic transmission consisting of an input shaft, an output shaft and first to third planetary gear sets comprises: first to seventh actuating elements constituting the first to third planetary gear sets; and shifting elements including first to fourth clutches and first and second brakes, wherein at least two of the shifting elements are actuated so that the first to seventh actuating elements are driven or restrained, thereby implementing eight forward speed and two reverse speed ratios. | 01-28-2016 |
20140209424 | Dual Clutch Device - The present invention relates to a dual clutch device which comprises: a retainer portion to which a rotation force is transmitted; a pair of plate portions provided to the retainer portion; disc portions which are respectively arranged at the plate portions; a herb portion connected to the disc portion; piston portions which respectively apply pressure to the plate portions; driving portions which respectively move the piston portions; and a restoration portion which is arranged between the driving portions and provides a restoration force to the piston portions. The dual clutch device, according to the invention, uses one restoration portion, thereby simplifying a flow path and reducing the size of a product. | 07-31-2014 |
20140174228 | Automated Manual Transmission - The present invention pertains to an automated manual transmission, and particularly to an automated manual transmission which can implement 7 forward gear changes and 1 reverse gear change. The present invention provides an automated manual transmission, which comprises: a first input shaft to which the power of an engine is transmitted; a second input shaft to which the power of an engine is transmitted; a driving gear section mounted to the first and second input shafts; a clutch section for transmitting or blocking the power of the engine with respect to the first input shaft or the second input shaft; a first output shaft to which the power is transmitted from the first input shaft or the second input shaft; a second output shaft to which the power is transmitted from the first input shaft or the second input shaft, and having a plurality of shaft portions which are disposed on a same axis; a driven gear section including a plurality of driven gears which are mounted on the first output shaft and the second output shaft; and a synchronization section for connecting or disconnecting the first output shaft and the second output shaft with respect to the driven gear section so as to implement multiple gear changes. The clutch section includes a first clutch which is mounted to the first input shaft so as to transmit or block the power of the engine and a second clutch which is mounted to the second input shaft so as to transmit or block the power of the engine. | 06-26-2014 |
