Abstract: A power train component such as a gearbox includes driving and driven, coaxially arranged cooperating gears which engage each other via teeth. The engaging end surfaces of the teeth are provided with a first chamfer and a second chamfer, in which the chamfer edge is offset from bisecting the tooth.

The invention facilitates smoother and less binding movement between the non-engaged and the engaged axial positions, such that the gear can be more easily shifted by the shifting fork in at least one direction.

Abstract: In a twin-clutch transmission, when a third shift valve (for example) goes out of order and the shift change accordingly becomes incapable of being carried out, the hydraulic pressure outputted from the third shift valve is controlled by a fourth shift valve operated by a first shift solenoid for a first shift valve. Accordingly, the hydraulic pressure outputted by a second linear solenoid is supplied to one of second hydraulic actuators, thereby enabling one of second predetermined transmission gear stages to be pre-shifted by use of a second power transmission path. When the first shift valve is used as a fail-safe, it is possible for the vehicle to make a minimum necessary run by setting up one of the second predetermined transmission gear stages. Furthermore, the fourth shift valve is driven by use of the existing first shift solenoid, thus minimizing the number of parts and cost.

This transmission and clutch assembly does not use any internal oil pressure to effect changing of gears and substantially reduces the rotating weight of the transmission when the vehicle is in high gear, because the clutch housing, clutch shaft, input gear and pressure members do not rotate when the transmission is in direct drive speed mode unlike other known transmissions.

Abstract: A transmission subunit with an intermediate shaft having continuous gears of progressive pitch diameters interposed between pairs of conventional gears. The geometry of the continuous gears permits input gears, output gears, and/or idler gears to freely and independently slide longitudinally the length of the intermediate shaft without disengaging. Helical or spur cut gears can be used throughout. During shifting, an idler quickly passes from a conventional gear to an intermediate, continuous gear where it changes speed ratio progressively until the new ratio is achieved. At this point the idler quickly moves on to the next conventional gear to complete the shift cycle. An automatic locking mechanism assures precise, fixed alignment. As an example, a semi-continuous subunit consisting of two idler gears and three or four conventional running gears bridged with two or three continuous gears combined with a planetary gearset provides 14 to 22 forward speeds and 7 to 11 reverse speeds.
