Abstract: The brake system includes a sun gear fixedly mounted to an input shaft. The sun gear is mounted inside a planetary chassis between two pinion gears. The sun gear has teeth protruding from its circumference on both sides thereof. The teeth are aligned in such a way that when the sun gear is turned to a neutral position, the teeth are engaged with the pinion gears, preventing a rotation of the pinion gears, and when the sun gear is rotated away from the neutral position, the teeth are disengaged from the pinion gears allowing the pinion gears to rotate. When no torque is applied to the input shaft, the sun gear is urged back to its neutral position. In a second embodiment, the sun gear is urged in a drag mode against the trailing side of the teeth on the pinion gears, for producing a pawl-and-latch noise during use.

Abstract: A controller has a command section, a control section, a time measurement section, and a command fixing section. The command section generates a command regarding the actuation state of a lock-up clutch in accordance with a condition value that is determined by the accelerator operating amount and the vehicle speed. The time measurement section starts to measure time when the accelerator operating amount drops to 0 with the current condition value maintained in a hysteresis range and the command section generates the acceleration slip executing command. When the accelerator operating amount is increased from 0, the time measurement section stops the measurement of time and resets the measured time to 0. The command fixing section fixes the command of the command section as an acceleration slip executing command in the period from when the time measurement by the time measurement section has started to when the measured time reaches a determination value.

Abstract: In a hybrid vehicle that includes an engine and a motor-generator connected to the engine through a power split device, upon acceleration in a running state, there may arise a case where the rotational speed of the MG1 enters a lockup area and, then, the MG1 cannot pull out of the lockup state with ease in such a manner that the rotational speed of the MG1 is shifted from a normal rotation area to a reverse rotation area, in accordance with an increase of a torque produced by the MG1. In this case, the engine is controlled such that a torque produced by the engine is decreased. Thus, the rotational speeds of the engine and MG1 are reduced entirely, so that the MG1 can pull out of the lockup state without increasing the torque produced by the MG1 any more.

Abstract: A motorcycle wheel attachment for replacement for a rear sheave or sprocket that attaches to the hub of the rear wheel. The outer perimeter of the apparatus resembles the outer perimeter of the replaced motorcycle sheave/sprocket so that the respective drive belt or chain can be affixed around the perimeter. With respect to the belt or chain, the engine and transmission, the attachment functionally replaces the sheave/sprocket. The attachment includes an enclosed inner gear system having a locked and unlocked position. In the locked position, none of the gears rotate with respect to the exterior of the attachment. In the unlocked position, the gears couple to the movement of the exterior of the attachment as well as the drive force exerted by the belt or chain. This coupled movement allows the attachment and wheel to rotate in a reverse direction using the forward drive of the engine, thereby giving the motorcycle reverse power.

With such a shifting gear, a pedal cycle may be given a unique function that when the cycle is moving forward, the changing of it's moving speed in the very moving direction may be in-situ realized by variating the shifting gear through pedalling to enable the crank to be rotating in either positive or inversive directions.

Abstract: A differential motion gear system to control the output speed ratio by changing the input direction. The gear system utilizes a planetary gearset to achieve the desired results. The input shaft may be directly connected to the sungear, the differential motion gear set, or to the ring gear. One or more one-way drive mechanisms are connected between a stationary case and one or more of the planetary gearset elements and between the planetary gearset elements and the output shaft. Selective braking of the planetary gearset elements, in conjunction with the change of direction of the input shaft causes the output shaft to rotate in a single direction, but at different output speeds.
