Continuously variable transmission system

A continuously variable transmission system that is characterized in that it includes at least:

• a first driving and regulating subsystem (S1) that transforms a rotating movement of a driving element connected to an input shaft into an oscillating angular movement with a variable amplitude at an output shaft (E2) of the first subsystem;
• the first subsystem (S1) comprises a first rod (B1) with a fixed radius (R), which transmits the rotating movement of an end of the first rod, being the input shaft of the first subsystem (E1), to a control gear (EC), the control gear (EC) being engaged with a control ring (CC) and spinning about an inner face of the control ring (CC), while said control ring (CC) is fixed in its position as determined by a driving element (EA) which uses a worm gear to drive an outer face of the control ring (CC) in order to control its relative position with respect to a reference position;
• the first subsystem (S1) comprises a second rod (B2) joined at a point (P) to the control gear (EC), said point (P) being located at a radius (R) equal to the radius of the first rod (B1) from a center of the control gear (EC), said point (P) at which the second rod is joined to the control gear is carried out in such a manner to allow a relative turn between the control gear (EC) and the second rod (B2);
• and a diameter of the control gear (EC) is equal to a radius of the inner face of the control ring (CC), a hypocycloid curve generated by the point (P) between the control gear (EC) and the second rod (B2) degenerates to a straight line that defines an inner diameter of the control ring (CC), driving the shaft of the driving element (EA) and modifying the position of the control ring (CC) with respect to the reference position, the different possible diameters are described and this way, the oscillation transmitted through the second rod (B2) to a rocker (B3) of the first subsystem (S1) is a function of the described diameter and will vary from an oscillation corresponding to a minimum amplitude at the reference position to that which generates a maximum amplitude, and which corresponds to a diameter that is out of phase at a right angle with respect to the reference angle;
• a second torque inertial regulating subsystem (S2) that incorporates at least an additional mass and in an epicyclic train and having an input shaft that receives the oscillating movement with a variable amplitude of the first subsystem (S1), obtaining a regulated and oscillating angular movement at an output shaft (E3) of the second subsystem (S2);
• the epicyclic train of the second subsystem (S2) includes a planet carrier (PS), which is attached to the input shaft (E2) of the second subsystem, a plurality of planet gears, (SA1) to (SA3), that engage with an inner face of a ring (C) of the epicyclic train, which has a distributed mass (M) and a sun gear (PL), which is attached to the output shaft (E3) of the second subsystem (S2);
• and
• a third movement rectification subsystem (S3) that converts the oscillating movement received from the second subsystem (S2) into a single direction of rotation at an output shaft of the third subsystem (S3).
