Patent number: 7765886Abstract: An automatic transmission that includes oil passages with a simple structure provided for twin clutches can allow the number of production steps to be reduced. The automatic transmission includes a number of gear trains equal to the number of speeds between a primary shaft and a countershaft. The automatic transmission performs connection and disconnection of a rotational driving force between a crankshaft and a gearbox by means of twin hydraulic clutches including first and second clutches, which are made of the same components and disposed on the axis of the primary shaft back to back. Oil passages can be formed into a more simple shape and can be configured to have the same total length. The first clutch performs connection and disconnection for first and third speeds, and the second clutch performs connection and disconnection for second and fourth speeds.Type: GrantFiled: March 30, 2006Date of Patent: August 3, 2010Assignee: Honda Motor Co., Ltd.Inventors: Yoshiaki Hori, Toshiyuki Sato, Eiji Kittaka

Patent number: 7467562Abstract: A vehicular transmission has a structure which enables a reverse idle gear to absorb and reduce excessive back torque inputted from drive wheels. At the time of reverse traveling motion, a counter shaft and a reverse gear are connected to each other through the intermediation of a clutch mechanism, whereby the power of the counter shaft is transmitted from the reverse gear, a driven gear, a hollow shaft, and a drive gear to the drive shaft by way of a final gear. When a large back torque is inputted to the final gear from the drive shaft, the inputted back torque is transmitted to the drive gear, and is then further transmitted to the driven gear by way of the hollow shaft. Since the hollow shaft is thin-walled and has reduced rigidity, it undergoes circumferential twisting due to the back torque inputted, whereby the back torque is reduced.Type: GrantFiled: March 30, 2006Date of Patent: December 23, 2008Assignee: Honda Motor Co., Ltd.Inventors: Takashi Nomura, Yoshiaki Hori, Seiji Hamaoka
