    Variable transmission by trapezoidal belt and twin hydraulic cylinders. Transmission that allows to vary the rotation ratio between a primary axis (1) and a secondary axis (2) in stationary and without circular movement in the axes or loss of transmission between both axes, as actuator has a main hydraulic cylinder (3) that when increasing the volume in its interior it displaces to the trapezoidal belt (4) in the primary pulleys (5) whose flanks describe a ramp, at the same time that a twin hydraulic cylinder (6) by the principle of communicating vessels lowers the belt trapezoidal (4) on the secondary pulleys (7).

    DESCRIPTION

    Variable transmission by V-belt and twin hydraulic cylinders.

    Technical sector 5

    The invention falls within the industry sector.

    State of the art
     10
    Nowadays, the transmission systems force to temporarily disconnect the rotation relationship between axes, either to change the pinion-crown in the systems with gears and to disengage for it, and / or to always be the axes in motion for it.

    These systems lose contact momentarily losing spin speed and / or 15 linear speed that they then have to recover again if what they want is to continue maintaining that initial speed with a new gear or continue increasing it.

    On the other hand, the inverter systems that do not lose contact have the disadvantage of always having to maintain a pre-established relationship between the two driving axles and operating by centrifugal force always related to the speed of rotation of the driving shaft.

    The disconnection at each change of speed ratio in clutch systems produces sharp variations that accentuate the pinion wear and more components involved in the clutch system.

    And on the other hand the variator systems do not allow to vary the relation between axes nor allow to increase the speed of the secondary axis keeping the revolutions of the primary axis fixed. 30

    The present invention allows to change the transmission ratio between the primary and secondary axes without turning any of them (change in stationary).

    In addition it also allows to vary the speed of the secondary axis keeping the 35 revolutions fixed in the primary.

    Detailed description of the invention

    The system would consist of a primary axis (1) connected to any type of energy source that can be printed by a circular movement and a secondary axis (2), these axes would be connected to each other by a V-belt (4).

    A primary hydraulic cylinder (3) connected by pipes to the secondary twin hydraulic cylinder (6) located on the secondary axis is located on the primary axis. Four. Five

    The main hydraulic cylinder (3) by increasing its volume in its inner chamber is stretched and by the principle of communicating vessels decreases the inner chamber of the secondary twin hydraulic cylinder (6), these cylinders are connected to the primary pulley (5) and Secondary pulley (7) and these pulleys with ramp flanks are connected 50 in turn to the V-belt (4) which transmits the movement from one axis to the other.

    When the internal chambers of the cylinders are interconnected and by the principle of the communicating vessels the main hydraulic cylinder (3) aspirates the fluid that is in the inner chamber of the secondary twin hydraulic cylinder (6), therefore when one is the other stretches simultaneously shrinks, the turning ratio between these axes can vary even without turning any of them. 5

    1. Variable trapezoidal belt transmission system (4) between a primary (1) and a secondary (2) axle, provided with variable pulleys (5, 7) by means of an actuator, characterized in that said actuator it comprises in each pulley 5 (5, 7) a hydraulic cylinder (3, 6) capable of varying the distance between the ramp flanks of the pulleys (5, 7), the inner chambers of the cylinders (3, 6) being communicated each other by a fluid as communicating vessels, so that if one cylinder increases its internal volume the other decreases it, in order to allow the transmission ratio to vary even when the primary axis (1) rotates at constant speed or when the axes (1, 2) do not rotate.
