20130143713 | CONE/FRICTION RING TRANSMISSION AND METHOD FOR A CONE/FRICTION RING TRANSMISSION - In order for it to be also possible to transmit relatively high torques in an operationally reliable manner with low power loss and with a low or inexpensive design outlay in a bevel friction ring gear mechanism, consisting of at least two component transmissions which are configured as bevel friction ring gear mechanisms and have a first adjusting device for a friction ring of the first component transmission and a second adjusting device for a friction ring of the second component transmission, wherein the bevel friction ring gear mechanism has a regulating device for regulating an axial position of the friction rings, it is proposed that the regulating device has at least one first part regulating device with a first reference variable and a second part regulating device with a second reference variable which is separate from the first reference variable, wherein the first component transmission has the first part regulating device for regulating the position of the friction ring of the first component transmission, and the second component transmission has the first part regulating device and the second part regulating device, but at least the second part regulating device, for regulating the position of the friction ring of the second part transmission. | 06-06-2013 |
20140011628 | INFINITELY VARIABLE TRANSMISSIONS, CONTINUOUSLY VARIABLE TRANSMISSIONS, METHODS, ASSEMBLIES, SUBASSEMBLIES, AND COMPONENTS THEREFOR - Inventive embodiments are directed to components, subassemblies, systems, and/or methods for continuously and infinitely variable transmissions (IVT). In one embodiment, a variator is adapted to receive a control system that cooperates with a shift nut to actuate a ratio change in an IVT. In another embodiment, a neutral lock-out mechanism is adapted to cooperate with the variator to, among other things, disengage an output shaft from a variator. Various inventive mechanical couplings, such as an output engagement mechanism, are provided to facilitate a change in the ratio of an IVT for maintaining a powered zero operating condition. In one embodiment, the output engagement mechanism selectively couples an output member of the variator to a ratio adjuster of the variator. Embodiments of a ratio adjuster cooperate with other components of the IVT to support operation and/or functionality of the IVT. Among other things, user control interfaces for an IVT are disclosed. | 01-09-2014 |
20150345598 | Controllable Mechanical Transmission For Downhole Applications - A transmission for rotatably coupling an input shaft with an output shaft about a longitudinal axis is disclosed, which may include a continuous variable transmission and an output torque sensing control mechanism. The continuous variable transmission may be a toroidal disc continuous variable transmission. The output torque sensing control mechanism may include a spring and an intermediary output shaft rotatably connected with an output rotating member of the continuous variable transmission, and the output shaft may be externally threaded and matable with an internally threaded portion of the intermediary output shaft. | 12-03-2015 |

20140274551 | CONTINUOUSLY VARIABLE TRANSMISSION WITH INPUT/OUTPUT PLANETARY RATIO ASSEMBLY - A continuously variable transmission is provided. The continuously variable transmission includes an input assembly, an output assembly, an input/output planetary ratio assembly and a torque feedback assembly. The input/output planetary ratio assembly is configured and arranged to set an input to output speed ratio. The input/output ratio assembly has a first portion that is in rotational communication with the input assembly and a second portion that is in rotational communication with the output assembly. The torque feedback control assembly provides an axial load force in response to a torque of a load coupled to the output assembly. Moreover, the torque feedback control assembly is coupled to provide torque feedback to the input/output planetary ratio assembly to at least in part control the input to output speed ratio of the input/output planetary ratio assembly. | 09-18-2014 |

20090069146 | OIL PRESSURE CONTROL APPARATUS - An oil pressure control apparatus includes a belt-driven continuously variable transmission, a primary regulator valve that regulates a line oil pressure that becomes a source pressure of oil pressure of various parts, and a gear oil pressure control valve that supplies gear oil pressure to a driving-side pulley of the belt-driven continuously variable transmission. A failsafe valve is provided between the gear oil pressure control valve and the driving-side pulley. When the gear oil pressure control valve or a linear solenoid valve that controls the gear oil pressure control valve fails, the failsafe valve is switched so as to supply the line oil pressure to the driving-side pulley, and other than during such the gear oil pressure control valve's failure or the electromagnetic valve's failure, the failsafe valve is switched so as to supply the gear oil pressure to the driving-side pulley. | 03-12-2009 |
20120202642 | Variator Switching Valve Scheme For A Torroidal Traction Drive Transmision - An apparatus for controlling a variator having at least one roller between two torroidal disks may include at least one actuator responsive to fluid pressure at separate high side and low side fluid inlets thereof to control torque applied by the at least one roller to the disks. First and second variator switching valves may each receive a first fluid at a first pressure and a second fluid at a second lesser pressure. The first and second variator switching valves supply the first fluid to the high side fluid inlet and the second fluid to the low side fluid inlet during two of four different operational states together defined by the variator switching valves, and supply the second fluid to the high side fluid inlet and the first fluid to the low side fluid inlet during each of the remaining two of the four different operational states. | 08-09-2012 |

20080220930 | Linear Actuator - A linear actuator includes permanent magnet annuli arranged about an armature core for axial movement in a tubular stator upon energisation of coils arranged in concentric association with the armature. The stator has portions extending radially inwards of the coils and towards one another beneath each coil, which define a spacing between the coil and the armature. The annuli have a substantially radially magnetised structure and the coils are configured for single phase power input. In one embodiment (FIG. | 09-11-2008 |
