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 a direction control assembly (forward, reverse and neutral) and 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. |

1. An infinitely variable, forward and reverse, direction control assembly for use with a speed converter, the infinitely variable direction control assembly comprising
an input shaft having first and second left sun gears attached to or integral with the input shaft, the second left sun gear being dispersed longitudinally along the input shaft to have a predetermined distance from the first left sun gear, first and second right sun gears, the first right sun gear being of a first spur gear transgear assembly and being attached to or integral with a first sleeve surrounding the input shaft, the first sleeve in turn being attached to or integral with an output gear, the second right sun gear being of a second spur gear transgear assembly and being located adjacent to the second left sun gear of the input shaft, the first left sun gear being associated with a first brake and a first carrier bracket, the first right sun gear being coupled to the output gear such that the first right sun gear and output gear have the opposite rotational direction as the input shaft, responsive to the first brake being actuated, and the second right sun gear being associated with a second brake and a second carrier bracket, the second right sun gear being fixed, third and fourth carrier brackets and the output gear having the same rotational direction as the input shaft, responsive to the second brake being actuated. |
