Multi-speed transmission with Hi-Lo output torque-transmitting mechanisms and gear sets |
摘要 |
A multi-speed transmission includes first and second output gear sets having co-planar intermeshing gears axially-spaced from one another. Each has a first gear intermeshing with a second gear, one of which is connected for common rotation with an output shaft or a first countershaft and the other of which is connected for rotation about and selectively engagable with the other of the output shaft and first countershaft by a respective output torque-transmitting mechanism. A direct drive torque-transmitting mechanism is selectively engageable for transferring torque from the input shaft to the output shaft when neither of the output torque-transmitting mechanisms is engaged. The first output torque-transmitting mechanism is engaged during underdrive gear ratios and the second output torque-transmitting mechanism is engaged during overdrive gear ratios. The order of engagement of torque-transmitting mechanisms during the underdrive gear ratios may be repeated during the overdrive gear ratios.
