Infinitely variable transmission embodied in a semi planetary configuration
View Patent ↗An infinitely variable transmission capable of shifting from infinity to zero speed ratios in forward and reverse is provided. The transmission offers reciprocal blocking and supports high torque and power, while requiring a fixed number of planetary gears and a hydraulic flow control, without brakes and/or clutch by varying the angular displacement or rotational movement separating the contained vectors (speed and torque) to exploit, in a reciprocal manner, the working flow by maintaining the full potential of the movement force source without a continuity flow break-up.
1. An infinitely variable transmission comprising:
a first gear set connected to a driving shaft, the first gear set comprising a first sun gear, a a second sun gear, and a first carrier, wherein the first gear set splits the angular motion of the first carrier between the first and second sun gears; and,
a second gear set connected with an output shaft, the second gear set comprises a third sun gear and a second carrier, wherein the first sun gear is meshed with the third sun gear, and the second sun gear is meshed with a second carrier.
2. The infinitely variable transmission of claim 1 , wherein the first gear set and the second gear sets are in different or identical vectorial angles.
3. The infinitely variable transmission of claim 1 , further comprising a geared hydraulic pump with external teeth meshed with the first carrier of the first gear set.
4. The infinitely variable transmission of claim 3 , wherein the geared hydraulic pump recirculates oil in a closed loop interfered by a valve.
5. The infinitely variable transmission of claim 4 , wherein the first carrier turns freely when the valve is open and the first carrier slows due to increased resistance when the valve is closed, such that the motion of second carrier of the second gear set is initiated, accelerating the speed of the output shaft.
6. The infinitely variable transmission of claim 4 , wherein the valve is an auto-piloted valve.
