Abstract:
1. A transmission system, the transmission system for governing rotational movement intermediate a transmission input shaft and a transmission output shaft, the transmission system comprising: an input shaft, the input shaft comprising an engine-engaging first input shaft end, a shaft-engaging second input shaft end, a rotation transmissive portion, and an input axis of rotation, the rotation transmissive portion extending intermediate the first and second input shaft ends for transferring engine-originated rotational motion to the transmission assembly by way of the first input shaft end; a plurality of cylinder arm assemblies, the cylinder arm assemblies being concentric about the input axis of rotation and comprising a reverse arm assembly and at least three forward arm assemblies, the cylinder arm assemblies each comprising an input arm end, an output arm end, and an inner arm diameter, the inner arm diameters for effecting varying gear ratios, the input arm ends each being independently geared to the rotation transmissive portion via the inner arm diameters, the rotation transmissive portion thereby enabling reverse rotational movement of the reverse arm assembly and forward rotational movement of the forward arm assemblies; an output shaft assembly, the output shaft assembly comprising an output shaft and a stepped ring, the output shaft comprising a shaft-engaging first output shaft end, a shaft-engaging second output shaft end, a rotation receptive portion, and an output axis of rotation, the rotation receptive portion extending intermediate the first and second output shaft ends, the stepped ring comprising a uniform inner diameter, at least four outer diameters, and a plurality of rod-receiving tunnels, the stepped ring receiving the rotation receptive portion at the inner diameter and being fixedly attached thereto, the rod-receiving tunnels being parallel to the output axis of rotation, the first output shaft end being rotatively mated with the second input shaft end, the output and input axes of rotation being coaxial, the input and output shafts being independently rotatable, the rod-receiving tunnels being rotatable about the output axis of rotation; a rod-translation system, the rod-translation system comprising a plurality of rods, bearing means for movement, and fixed rod-translating means, the rods being received in the rod-receiving tunnels and each comprising an arm-engaging first rod end and a bearing-engaging second rod end, select second rod ends being cooperatively associated with the bearing means, select bearing means being cooperatively associated with each cylinder arm assembly, the rod-translating means for selectively translating the bearing means and rods intermediate an arm-engaged position and an arm-disengaged position, select first rod ends engaging a select output arm end when in the arm-engaged position for imparting rotational movement from the select output arm end to the output shaft via the stepped ring, the bearing means enabling rotational movement of the output shaft relative to the rod-translating means; and assembly-governing means, the assembly governing means comprising a power source, circuitry, central-processing means, and rotation-sensing means, the power source energizing the central-processing means, the rotation-sensing means, and the rod-translation system by way of the circuitry, the rotation-sensing means being cooperatively associated with the output shaft for sensing the rotational speed thereof, the central-processing means being programmed to direct the rod-translating means according to pre-determined rotational speeds as comparable to actual rotational speeds sensed by the rotation-sensing means, the transmission system thus for governing rotational movement intermediate the input shaft and the output shaft.
