Abstract: For a first gear ratio, the flyweights engage the clutch and thus connect the input to the sun wheel, whilst the ring gear is immobilised by the free wheel. For the second gear ratio, the flyweights push the ring gear against the axial thrust of the helical teeth in a direction causing the engagement of the clutch against the ring and thus, at the same time, the disengagement of the clutch. The thrust produced by the teeth on the ring gear decreases and transmission then occurs from the input to the ring gear, whilst the sun wheel is immobilised by its free wheel. The speed increases further, the flyweights rise further, compress the prestressed springs and push the ring in the direction of the engagement of the clutch, which produces direct drive.

Abstract: A driving device includes a power supply unit and a torque converter. The power supply unit outputs a constant power. The torque converter has a gear train that is connected to the power supply unit and interconnects a flywheel and an input shaft in order to respectively transmit a first part and a second part of the power to the flywheel and the input shaft. The input and output shafts have respectively first and second variable-diameter pulleys on which a belt member is trained. The effective diameters of the first and second pulleys are automatically varied in response to the torque exerted on the input and output shafts to maintain the rotational speed of the output shaft at a constant level while the flywheel compensates for power variation of the output shaft without changing the power of the power supply unit.

Abstract: A clutch engaged by means of flyweights and a spring directly meshes an input sun gear and an output planet gear carrier. When engagement pressure is insufficient for torque to be transmitted, a crown wheel slows down and is stopped by a free wheel, while an axial thrust (Pac) produced by helical teeth releases the clutch, so that the device functions as a step down device. A control unit accelerates the onset of the procedure. The device enhances the comfort and reduces stresses of the transmission.

Abstract: The crown wheel of a planetary gear is connected to an input shaft while the planet carrier is connected to the output shaft. The sun wheel is locked by means of a free wheel when the clutch is released. The device then operates as a reduction gear. The sun wheel rotates with the crown wheel and the planer carrier when the clutch is engaged. The axial forces (F.sub.AP, F.sub.AC), sustained by the sun wheel and the crown wheel when in gear-reduction mode, and resulting from the helical tooth configuration, tend through the stop to compress a spring and release the clutch. When in direct drive and beyond a certain torque, the clutch slips, thereby generating the above-mentioned axial forces which compress the spring and accelerate disengaging. The device operates as a reduction gear until the torque on the shaft is reduced, thereby, enabling the spring to re-engage the clutch.

Abstract: A planet gear (9) connected to the input shaft (2a) and a planet carrier (13) connected to the output shaft (18) can be coupled by a clutch (18) operated in clamping by fly weights (29) and a spring (34) to bring about direct engagement. If clamping is insufficient for torque to be transmitted, the crown wheel (8) slows down and is then immobilized by the free wheel (16). The device then acts as a reduction gear, with a piston (44) acting on the housing (2) in the direction which will release the clutch (18) and applying a brake (43) preventing the crown wheel (8) from rotating even in the direction normally permitted by the free wheel (16). Narrow bleed ducts (151, 172) of a chamber (40) associated with a piston (44) and a damping chamber (171) prevent sudden variations in the state of the clutch (18).

Abstract: This smoothly automatic changing ratios gear mechanism for use in devices as small as toys and as large as the heaviest industrial machines is an arrangement of planetary gear sets which provide divergent ratio gear tracks driven by an arrangement of components for dynamically positioning virtual fulcrum points along virtual balance beams thus automatically realizing a multiplicity of gear ratios. The gear ratio changes result from the relationship of the amplitude of force driving the system acting against the variable bias of spring and centrifugal forces that tend to keep the fulcrums positioned to affect high RPM output. The gear tracks are arranged as mirror images of each other and in a manner such that the ring gear of an input planetary gear set is tied to the sun gear of an output planetary gear set and vice versa thus forming divergent ratio gear tracks.

Abstract: A transmission apparatus in which a differential-type transmission device has rotating elements with intermeshing teeth, one of which elements is connected to an input shaft and the other to an output shaft. One of the rotating elements is a reaction element, and the transmission apparatus has a selective locking mechanism mounted operatively between the reaction element and a housing of the transmission apparatus. The selective locking mechanism has a free-wheel for enabling the reaction element to rotate in the same direction as the input shaft and the output shaft when a selective connection device connects the rotating elements of said differential mechanism in order to cause direct drive operation. When the freewheel is locked, the reaction element is integral in rotation with a rotor of a brake which is able to be selectively released in order to release the rotor and the reaction element in relation to said housing.

Abstract: A power transmission shaft which transmits rotational energy of a flywheel is divided into a first shaft section adjacent to the flywheel and a second shaft section adjacent to a power take-off gear. A planetary gearing is arranged between the shaft sections and is adapted to be driven by a servo motor. A power take-off gear is mounted on an output section of the planetary gearing so as to transmit the power to drives. The servo motor controls the rotation of the output section of the planetary gearing to vary the rotation of the power take-off gear so that the action velocity of the slide or the like can be freely controlled and press working for different kinds of materials can be carried out.

Abstract: The speed-responsive clutch has axle-free rocking flyweights which are rockingly mounted in correspondingly shaped recesses of a cage. The rocking movement of the flyweights corresponds to a substantially radial movement of the center of gravity of the flyweights and to a substantially axial movement of an actuator portion of the flyweights for variably pressing friction disks of the clutch.

Abstract: A rotational energy coupler generally regarded to as a transmission is described, wherein rotational energy is transmitted through inertial media. An input unit transmits rotational energy to a set of inertial masses by driving the inertial masses to gyrate. An output unit recovers rotational energy from the gyrating inertial masses by altering their natural travelling paths through a guiding system that guides the gyrating inertial masses into paths along which the distance to the axis of rotation of the output unit is not constant. As a result, an unidirectional torque is generated on the output unit. If the output unit rotates, rotational energy is consumed, if not, rotational energy is conserved. The magnitude of the torque so generated is related to the rotation rate difference between the input unit and the output unit in an exponential manner, namely: the magnitude of the torque is proportional to the square of the rotation rate difference.
