Publication number: 20140329638Abstract: Disk Continuously Variable Transmission is a Disk based, semi or full Continuously Variable Transmission (DCVT) using a Roller engaging and rotating with the surface of a typically power Input Disk. The Roller is Geared to and rotates a power Output Arm. Sliding said Roller between Disk's Center and Circumference by a Control mechanism changes the relative rotation speeds of the Disk and Roller & Arm. Said engagement is by Friction or Teeth on Roller's body Geared to Dents across the Disk. Many techniques for making said Geared Slide smooth and Continuous are introduced. DCVT can be also constructed as a Differential dividing power between say left and right and or front and rear wheels of a car.Type: ApplicationFiled: May 2, 2014Publication date: November 6, 2014Inventor: AHMAD AMIRI

Patent number: 8568269Abstract: Linearly adjustable torque transmission systems and methods for a power driven machine are provided. The system can include a first wheel adapted to be rotatably driven. The system can further include a second wheel positioned proximate the first wheel that can engage the first wheel such that rotational movement of the first wheel can impart rotational movement to the second wheel. The second wheel can be coupled to a shaft with bearings between the second wheel and the shaft such that the second wheel is movable along the shaft in a lateral direction while the second wheel is coupled to the shaft wherein rotational movement of the second wheel rotationally moves the shaft.Type: GrantFiled: October 5, 2007Date of Patent: October 29, 2013Assignee: Honda Motor Co., Ltd.Inventors: Andrew Joseph McDaniel, Christopher Wayne Vaughn

Patent number: 8419589Abstract: An infinitely variable transmission, in which the driver and driven members can exchange their roles—with the driver becoming the driven, and vice versa. The initially chosen driver carries within it a number of movable parts, which the driving forces bring into contact with the driven member, in a manner designed to produce a momentary lock between the driver and driven members, at the point of the torque transfer between them. In one embodiment the driven member—which can be a flat disc—is clamped between two oppositely placed drivers. Infinite variability is achieved by controllably relocating the fixed diameter drivers to smaller or larger diameter points on the so clamped disc. The output can be harvested from the rotation of said driven disc directly. Or one or more driver members like these which are used to rotate said disc, can be brought into contact with different locations on said disc, and become driven by it.Type: GrantFiled: May 29, 2009Date of Patent: April 16, 2013Inventors: Lawrence George Brown, Gregory A M Brown, Brian Alexander Brown

Publication number: 20120190497Abstract: The inventive technology described herein generally relates to the field of power generation. More specifically, methods and apparatus for a power generation coupler utilizing perhaps multiple generators coupled through a power generation coupler to at least one rotational movement element such that said coupled connection is dynamically movable across the surface the rotational movement element so as to maintain an electrical output at a constant generator rotation(s) per minute (RPM) according to the varying rotational velocity along the radius of a rotational movement element. In some embodiments such coupled generators may be sequentially loaded and disengaged to such rotational movement element to maintain an electrical output at a constant generator RPM. Certain embodiments may include a static power generation coupler as well as an electrically dynamic power generation coupler such that the current applied to the stator of a generator may dynamically alter that generators resistance.Type: ApplicationFiled: April 2, 2012Publication date: July 26, 2012Applicant: AIRGENESIS LLCInventor: Danny J.

Patent number: 7584040Abstract: The following steps are performed in the control method: determining a mode of operation from amongst a permanent mode and a transient mode, as a function of a set of variables comprising said estimated values; correcting the value of the speed of rotation of the outlet shaft in such a manner that: if the mode has been determined as being the permanent mode, then the moving average (L?) of the gear ratio (L) over a period (T) of a plurality of unit time intervals lies between a first threshold value (S1) that is negative and a second threshold value (S2) that is positive; and if the mode has been determined as being the transient mode, then said moving average (L?) of the gear ratio (L) lies outside the range of values defined by the first and second threshold value (S1, S2).Type: GrantFiled: February 3, 2004Date of Patent: September 1, 2009Assignee: Peugeot Citroen Automobiles SAInventor: Stéphane Rimaux

Publication number: 20080125281Abstract: A variable speed transmission having a plurality of tilting balls and opposing input and output discs is illustrated and described that provides an infinite number of speed combinations over its transmission ratio range. The use of a planetary gear set allows minimum speeds to be in reverse and the unique geometry of the transmission allows all of the power paths to be coaxial, thereby reducing overall size and complexity of the transmission in comparison to transmissions achieving similar transmission ratio ranges.Type: ApplicationFiled: February 8, 2008Publication date: May 29, 2008Applicant: FALLBROOK TECHNOLOGIES INC.Inventors: Donald C. Miller, David J. Allen, Robert A. Smithson

Patent number: 6502335Abstract: A self-propelled power implement having a friction drive system to transmit rotation from the engine to the wheels. The friction drive system includes an output disc and a friction disc. The output disc rotates in response to rotation from the engine's output shaft. The friction disc is coupled to the implement's wheels, and contacts the output disc and rotates in response to rotation of the output disc. The location on the output disc that the friction disc contacts determines the rotation speed of the friction disc. A flexible member is interconnected to the friction disc and a controller, and movement of the controller causes the flexible member to actuate the friction disc radially in relation to the output disc. The flexible member adjusts the location on the output disc that the friction disc contacts, and thereby adjusts the rotation speed of the friction disc and the wheels.Type: GrantFiled: March 16, 2001Date of Patent: January 7, 2003Assignee: Ariens CompanyInventors: Perry Prochnow, John Adrian, Scott Deschler

Patent number: 5795259Abstract: A continuously variable transmission in which a ratio transfer bearing whose axis is at right angles to a friction disc against which it interacts by friction is moved across the face of the friction disc to continuously vary the transfer ratio between the two. The ratio transfer bearing is varied by means of a jackscrew operated by a train of bevel gears.One friction disc and ratio transfer bearing on the input side and a second friction disc and ratio bearing on the output side are connected through an idler bearing against which the two ratio transfer bearings operate. The jackscrews which move the two ratio transfer bearings are operated through the bevel gear linkages in an inverse fashion so that a higher ratio on one friction disc results in a lower ratio on the other friction disc and inversely. By varying the two transfer ratios inversely, a wider range of output ratios is obtainable.Type: GrantFiled: November 15, 1996Date of Patent: August 18, 1998Inventor: David S. Stoliker
