| 476007000 | WITH FRICTION ENHANCING FLUID | 6 |
| 20110111918 | BEVEL FRICTION RING GEAR - According to the invention, a bevel friction ring gear which transmits torque between the two bevels with both bevels mounted on a chassis by bearings may be provided which has a still greater efficiency, wherein at least one of the bevels has a bearing to both sides and that the first of the bearings is sealed relative to the bevel and the second of the bearings is open with relation to the bevel. | 05-12-2011 |
| 20110143881 | CONICAL FRICTION RING TYPE CONTINUOUSLY VARIABLE TRANSMISSION DEVICE - A conical friction ring type continuously variable transmission device configured a ring is provided such that it is interposed between opposing inclined surfaces of a first and second conical friction wheels so as to surround the first conical friction wheel. In this configuration, power is transmitted by contact between the ring and the first and second conical friction wheels, which moves the ring in the axial direction to steplessly change speed. A portion of the ring is submerged in an oil reservoir in a lower portion of the space when the ring is moved to any position in the axial direction. An oil guide is disposed on an axial partial region on the small diameter side of the first conical friction wheel, and guides oil raked up from the oil reservoir due to the rotation of the ring toward the first conical friction wheel. | 06-16-2011 |
| 20110152030 | CONICAL FRICTION RING TYPE CONTINUOUSLY VARIABLE TRANSMISSION DEVICE - A conical friction ring type CVT device configured with a ring interposed between opposing inclined surfaces of first and second friction wheels so as to surround the first wheel. A portion of the ring is submerged in an oil reservoir, and power is transmitted by contact between the ring and the first and second wheels, such that the ring in moves in the axial direction to steplessly changes speed. When the CVT device is mounted in a vehicle, a rotational direction is set such that, during forward travel of the vehicle, opposing, portions of the first and second wheels move upward from below. An oil strainer is disposed on a side of the second wheel opposite the axis of the first wheel with respect to the axis of the second wheel. Furthermore, a guide member is disposed on at least an upper portion of the second wheel. | 06-23-2011 |
| 20120157261 | STEPLESS GEAR RATIO VARIATOR - A stepless gear ratio variator for wind generators wherein the transmission of motion between a driving member and a driven member takes place through friction of the respective convex contact surfaces translating simultaneously along respective incident axes of rotation; these surfaces being constrained, in use, to remain constantly in contact by means of a pair of support brackets mutually connected in an articulated manner by means of a pair of plates, pivoted to the same support brackets according to axes passing through the centre of the contact surfaces of the driven and driving members. | 06-21-2012 |
| 20150011355 | Powered Metal Variator Components - The use of powder metal components in a variator is disclosed. Traction fluid of various sorts may be used in the variators, not just high performance synthetics or application specific lubricants. | 01-08-2015 |
| 20160377153 | ASYMMETRIC TOROIDAL TRANSMISSION SYSTEM - An input shaft being configured into spline engagement with an input wheel wherein the input wheel slides axially along the input shaft; an output shaft into engagement with the input shaft, and wherein an output wheel is configured to slide axially along said output shaft; a variator wheel being configured to drive the input wheel or output wheel without direct contact; a traction fluid to enable the variator wheel to drive at least one of the input wheel and output wheel without direct contact; a toroidal cavity for containing the traction fluid and form an enveloping toroidal cavity when the input wheel and output wheel are aligned together; and an actuator for controlling the axial sliding of the input and output wheel on their respective splined shafts. | 12-29-2016 |
