  • Patent number: 8814745
    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 hybrid power driving system for a vehicle comprises an internal-combustion engine, a first electric motor, a second electric motor, a planetary coupling mechanism, a speed-reduction mechanism and a differential mechanism. An output shaft of the internal-combustion engine is connected with an input shaft of the first electric motor, and an output shaft of the first electric motor is connected with an output shaft of the second electric motor via a first clutch. The output shaft of the second electric motor is connected with one of a sun gear and a ring gear of the planetary coupling mechanism at a position of the output shaft along its axial direction. And the output shaft of the second electric motor is connected with the other one of a sun gear and a ring gear at another position of the output shaft along the axial direction via a second clutch.

    Abstract: Infinitely variable motion control (IVMC) provides motion control without any requirement for changing gears or use of a clutch. A spur gear transgear, defined as a system having an input, an output and a control, a variable pitch cam having an eccentric inner and outer cam assembly and a driver may be used to form a speed converter. The speed converter is used in various forms to provide an infinitely variable transmission, a differential, embodiments of wind and river turbines and pumps/compressors. In one embodiment, the speed converter drives first and second directional control assemblies to provide a vehicle with zero turn radius. A variable torque converter may be used in various embodiments to control torque from a minimum to a maximum by controlling movement of a rotor along a shaft in relation to a stator.
