Embodiment Construction

[0065] The present invention can be further illustrated by the following examples:

[0066] A kinematic analysis of the transmission system is performed according to an embodiment of the present invention. Figure 10 A form of drivetrain is illustrated in . The input side of the transmission system is equipped with a small DC motor with an integral reduction gear set to drive the input shaft, so that the input shaft drive speed is maintained in a constant payload range, which simplifies the study and display of different operating mechanisms.

[0067] This output is the handwheel. Two control wheels, each connected by a right angle bevel gear to its intermediate shaft in the drive train. While the control II wheel is connected to the sun gear, the control I wheel is connected to a gear that meshes with the ring gear. The relationship between the two control wheels is fixed so that a given output / input ratio can be obtained by driving one control wheel at a specific speed or ...

Abstract

A transmission system having an input shaft for receiving / imparting rotation into the transmission system and an output shaft for delivering rotation from the transmission system, a flywheel component which has a ring gear portion and planet gear portion, wherein rotation of the input shaft causes rotation of the flywheel component, a first transmission shaft and a first transmission component, wherein rotation and / or orbital motion of the flywheel component is affected by the rotation or non-rotation of the first transmission shaft and by the rotation or non-rotation of the first transmission component, a second transmission shaft, wherein the first transmission component rotates if the second transmission shaft rotates, a second transmission component which rotates if the second transmission shaft rotates, wherein rotation or non-rotation of the second transmission component and rotation or non-rotation of the first transmission shaft affect the overall / net output shaft rotation, at least one modulator shaft the rotation or non-rotation of which is linked with the rotation or non-rotation of one of the transmission shafts, wherein a continuously variable accelerating or retarding torque can be applied to the modulator to accelerate or retard the rotation of the transmission shaft with which the modulator is linked, whereby this continuously variable acceleration or retarding of the rotation of the transmission shaft enables continuous variation of the speed and / or direction of the output rotation relative to the input rotation.

Description

Field of Invention [0001] The present invention relates to transmission systems, including but not limited to gearboxes. Background of the Invention [0002] Generally speaking, transmission systems are used to convert rotation, such as the rotation of the output shaft of an engine or other prime mover, into rotation at different speeds or directions, or into rotations at different speeds and directions. A gearbox is a common form of drivetrain. A common use of gearboxes is to convert high speed and low torque rotation into low speed and high torque rotation. A car gearbox is a good example. [0003] The internal combustion engine of a conventional automobile usually operates at a speed between 800 rpm and 7000 rpm. Therefore, the rotational speed of the output drive shaft ("crankshaft") of the engine is between 800 rpm and 7000 rpm. But for an ordinary car with a speed between 0km / hr and 120km / hr, assuming that the outer diameter of the wheel (including the tire) is abo...
