Abstract: A stepper motor driven actuator that eliminates the need for a position sensor is provided. The stepper motor rotates a cam in a control piston valve. In a single nozzle embodiment, pressure balance is maintained by a spring preload on one end of the piston in one embodiment, and by hydraulic pressure acting on a double diameter end portion of the piston in another embodiment. As the cam is rotated, the change in the gap between the nozzle and the cam changes the pressures on the control piston ends, which forces the piston in the direction that will re-equalize the pressure based on the cam-nozzle gap. As a result, the head or rod of the actuator piston receives high pressure flow, thereby moving the actuator. Movement of the actuator rod provides mechanical feedback to the cam, causing the cam to move back to its mechanical null position.

Abstract: A low energy stepper motor driven actuator that eliminates the need for a position sensor is provided. The stepper motor rotates a cam in a control piston valve. The cam rotation increases the gap between the cam and nozzle on one side of the cam and decreases the gap between the cam and nozzle on the other side. The gap differences affect the pressures on the control piston ends, which forces the piston in the direction that will re-equalize the cam-nozzle gaps. As a result, piston moves to a position such that the head or rod of the actuator piston receives high pressure flow, thereby moving the actuator. Movement of the actuator rod provides mechanical feedback to the cam, causing the cam to move back to its mechanical null position.

Abstract: A drive train of a motor vehicle includes a gear arrangement with at least two gear elements moveable relative to one another acts in a torque transmission path between an internal combustion engine and a transmission. The gear arrangement being connected between a drive-side flywheel mass and a gear-side flywheel mass. The gear arrangement includes at least one additional mass having a center of gravity (Sp) which is displaceable radially in relation to an axis of rotation (D) of the torque transmission path as a function of a relative position of the at least two gear elements. In the event of a change in the relative rotary angle between the flywheel masses, a moment of inertia of the torque transmission path also changes, so that there is no definite resonant point and the torque transmission path takes effect as a self-steadying system. Furthermore, the additional mass may be arranged to generate a centrifugally dependent return force directed toward a specific relative rotary angle position.

Abstract: A transmission utilizes oscillating torque to vary the mechanical power transmitted to a load. An arm assembly is rotatably coupled to a frame. At the ends of the arms are eccentric masses, rotatably coupled thereto. An input shaft rotates the masses about the ends of the arms. The rotating masses produce an oscillating torque that causes the arms to oscillate. The arms are coupled to an output assembly. The output assembly utilizes one way clutches, with one clutch reversed relative to the other clutch. The one way clutches convert the bidirectional rotation of the arms to unidirectional rotation for the load. The output speeds of the transmission are controlled by providing at least two side by side rotatable masses and varying the phase of one of the masses relative to the other mass. Varying the phase changes the center of gravity of the masses, thereby affecting the torque applied to the arms.

Abstract: The invention relates to an automatic continuously variable positive mechanical transmission, making it possible to avoid using a hydrodynamic torque converter and a switchable gearbox. A planetary unit (44) linking an input shaft (30), transmitting a working torque CM, to an output shaft (31) transmitting a load torque CR. A reaction torque RC resting on a fixed point (35) of the case is added to the working torque in the planetary unit (44) via two successive planetary centrifugal devices (36, 37) with eccentric weights. The second centrifugal device (37) permanently balances the three torques CM, CR and RC. The first centrifugal device (36) transmits the reaction torque CR to the second which it sets using a setting of the eccentricity for its weights. Such a transmission can drive the output shaft at a continuously variable speed between zero and a speed equal to or greater than that of the input shaft. It is applied to driving vehicles or variable speed machines.

Abstract: A ring gear and a plurality of planet gear carriers diametrically disposed, at substantially equal angles to each other, in a plane therewithin, each carrier rotatably supporting a separate one of a pair of planet gears at each opposite end thereof. The planet gears engage with and are rotated by the ring gear. Each planet gear has an eccentrically disposed mass that revolves about the center of rotation of the planet gear while revolving about the center of rotation of the planet gear carrier, creating centrifugal and Coriolis forces that are additive. An instant angular disposition, with respect to its planet gear carrier, of the center of mass of one of a pair of planet gears is always the same as that of the other of the pair but does not coincide with that of any other planet gear. This creates a couple that is applied to an output shaft when the force of the former and the rotation of the latter are in the same direction. When they are not, the couple is applied to a reaction plate.

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 driving hub (6) connected to a first shaft (3) rotatably carries primary planet wheels (10) meshing with first (11) and second (12) sun wheels in coaxial relation. The first sun wheel (11) is fastened to a helical crown gear (16) meshing with auxiliary planet wheels (18) rotatably linked to the second sun wheel (12). Eccentrically projecting from the auxiliary planet wheels are respective interconnecting elements (22) guided in a trochoidal rolling track (23) formed in a guide member (24) fastened to a second shaft (5). Each auxiliary planet wheel (18) is driven by a piston (28) engaged in a pressurization chamber (29) formed in the second sun wheel (12). A fluid supplying circuit (30-35) sends oil under pressure into the pressurization chambers (29) in order to transmit axial thrusts to the auxiliary planet wheels (18), which thrusts, by effect of the helical toothings, produce balanced forces interacting with a motive power so as to transmit motion from the first (3) to the second (5) shaft.
