Abstract: A self-locking device for a gear set is configured to permit forward-driving an input in either of first and second rotational directions and for substantially preventing an output from being back-driven in either of the rotational directions. The device includes a gear disposed to rotate with a drive shaft. The device further includes first and second releasable couplings coupled to the gear and, respectively, to first and second ratchets. The first ratchet is disposed to prevent rotation in a first direction and to permit rotation in a second direction. The second ratchet is disposed to prevent rotation in the second direction and permit rotation in the first direction. The device may be useful, for example, in a valve gearbox. A gearbox and a method of fabricating a gearbox are also disclosed.

Abstract: A gate-type shift lever device in which a pin is formed at a mounting piece formed at a back wall portion of a base, which pin axially supports a plate switch. Two levers are formed at the plate switch. A shift lever abuts and presses one of the levers during a shift operation from a “D” position to a “4” position. The shift lever abuts and presses another of the levers, during a shift operation from a “2” position to an “L” position. In accordance with rotation of the plate switch due to the pressing forces received by the levers, a holder contact moves transversely. Thus, the shift operations from the “D” position to the “4” position and from the “2” position to the “L” position can be detected.

The input gear assembly is positioned next to one of the wheel ends so that the vehicle floor can be lowered to facilitate passenger access to the vehicle. Each wheel end includes a gear reduction assembly with a ring gear rotatably mounted within a gear housing. A drive gear is operatively coupled to the input gear assembly and is in meshing engagement with the ring gear. The gear reduction assembly also includes an output or driven gear, which is larger than the drive gear, to provide the desired gear reduction. The driven gear is also in meshing engagement with the ring gear. A pair of idler gears is rotatably mounted within the gear housing and are in meshing engagement with both the drive and driven gear. The idler gears and drive gear do not have a common centerline.

Abstract: A starting apparatus for an internal combustion engine includes an output shaft rotated by an electric motor and a pinion shaft connected to the output shaft by a one-way clutch. The output shaft is connected to the clutch by a helical spline, and the pinion shaft is connected to a pinion by another helical spline. The splines have the same pitch angle as each other and spiral in a direction opposite to a direction in which the output shaft is rotated by the motor. This structure prevents a locked state in which the pinion can neither engage with or be retracted from a ring gear of an engine to be started.

Abstract: A transmission has only a single, minimal orbiter in which an input gear and an output gear, each being connected to separate input and output shafts, are interconnected through an orbiting cluster gear that meshes with only the input and output gears. The cluster gear is carried by a web that is itself rotated by a hydraulic control motor through a first clutch. When rotation of the web is prevented, rotation of the input gear produces rotation of the output gear at a predetermined reduction of the input drive, this gear reduction being continuously diminished proportional to the speed of rotation of the web in a first direction. When the vehicle reaches highway speeds, the control motor is disconnected and a second clutch is activated to connect a predetermined overdrive that is located between the engine drive and the transmission rather than being conventionally positioned between the transmission and the final output shaft.
