| 20110053717 | CONTINUOUSLY VARIABLE TRANSMISSION - A continuously variable transmission configured to transmit a rotational driving force of one pulley to another pulley by a driving-force transmitting means wound between the two pulleys, wherein each of the two pulleys is configured to vary a groove width thereof, the continuously variable transmission including: an engagement-receiving portion provided to the driving-force transmitting means, in a side of the driving-force transmitting means on which the driving-force transmitting means is wound on the pulleys; and a movable engaging portion provided to a shaft portion of at least one of the two pulleys, wherein the movable engaging portion is movable in a radial direction of the shaft portion to protrude from and escape into the shaft portion, wherein the movable engaging portion is configured to protrude from the shaft portion so as to engage with the engagement-receiving portion at least one of when a pulley-ratio region is in a setting for highest speed and when the pulley-ratio region is in a setting for lowest speed. | 03-03-2011 |
| 20110207566 | DRIVING PULLEY OF A CONTINUOUSLY VARIABLE TRANSMISSION - The driving pulley has a fully clutched mode of operation where a drivebelt and a driveshaft are coupled together in a torque transmitting engagement and also has an unclutched mode of operation where there is substantially no torque transmitting engagement between the drive belt and the driveshaft. The driving pulley comprises at least one transitional clutch spring that is in a first position when the driving pulley is in the unclutched mode of operation and that is in a second position when the driving pulley is in the fully clutched mode of operation. The at least one transitional clutch spring remains substantially in its second position regardless of the relative axial distance between the sheaves when the driving pulley is in the fully clutched mode of operation. A method of operating a driving pulley is also disclosed. The proposed concept provides a smoother engagement during the transition from the unclutched mode to the fully clutched mode. | 08-25-2011 |
| 20110263363 | Radial diaphragm spring clutch - A clutch includes a stationary sheave, a cam attached to the stationary sheave, and a movable sheave that is axially movable relative to the stationary sheave along the cam. A thrust bearing includes an outer race and an inner race, wherein the outer race is attached to the cam. A first radial spring includes a radially outward annular portion and an radially inward finger portion, wherein the radially outward annular portion is mounted on the movable sheave and wherein the radially inward finger portion bears against the inner race. In another aspect, a clutch includes a stationary sheave, a cam attached to the stationary sheave, and a movable sheave that is axially and rotationally movable relative to the stationary sheave along the cam. | 10-27-2011 |
| 20120100944 | ELECTRICAL CONTROL BELT CONTINUOUSLY VARIABLE TRANSMISSION SYSTEM - An electrical control belt continuously variable transmission system controls a movable driving half-pulley or movable driven half-pulley initiatively, by changing a driving interval between the movable driving half-pulley and a fixed driving half-pulley or a driven interval between the movable driven half-pulley and a fixed driven half-pulley, respectively, depending on different statuses, in order to adjust a velocity ratio. By manipulating the movable driving half-pulley or the movable driven half-pulley, the system may further form a driving gap between the movable driving half-pulley and a transmission belt or a driven gap between the movable driven half-pulley and the transmission belt, such that the power is cut off. Clamping the movable driving half-pulley or the movable driven half-pulley to the transmission belt may restore the outputting of the power. | 04-26-2012 |
| 20120115656 | ELECTRIC-CONTROL BELT-TYPE VARIABLE-SPEED TRANSMISSION MECHANISM - An electric-control belt-type continuous variable-speed transmission mechanism includes a driving-shaft, a driven-shaft, a driving-wheel, a driven-wheel, a transmission belt, a force-exerting device, an electric-control motor speed-adjusting device and an idle wheel. The electric-control motor speed-adjusting device operates along with the driving-wheel and the driven-wheel to dynamically control and adjust the overall configuration position of the transmission belt to thereby achieve effects of variable speeds, separation and restoration of dynamics. The idle wheel is rotatably disposed on the driving-shaft or the driven-shaft to axially support the transmission belt during the state of separate dynamics to prevent friction therebetween. | 05-10-2012 |
| 20120214627 | BELT-TYPE STEPLESS TRANSMISSION - A belt-type stepless transmission is provided with: an input shaft; an input pulley having a stationary sheave and a movable sheave; a transmission shaft disposed parallel to the input shaft; an output pulley having a stationary sheave and a movable sheave; a belt wound around the input pulley and the pulley; an output shaft disposed coaxially with the transmission shaft; and a cam mechanism having a sheave-side cam which is provided and affixed to the movable sheave and a shaft-side cam which is provided and affixed to the output shaft and causing the sheave-side cam and the shaft-side cam to make contact with each other to thereby enable the transmission of torque between the movable sheave and the output shaft and apply an axial pressing force corresponding to the torque to the movable sheave. | 08-23-2012 |
| 20120309569 | ADJUSTABLE PULLEY FOR A CONTINUOUSLY VARIABLE TRANSMISSION - Adjustable pulley ( | 12-06-2012 |
| 20140031155 | Driven-Side Pulley - The present invention provides a driven-side pulley including a fixed sheave supported by a driven shaft that is relatively rotatable around an axis line and immovable along the axis line, a movable sheave supported by the driven shaft that is relatively rotatable around the axis line and movable along the axis line, a spider supported by the driven shaft that is relatively non-rotatable around the axis line and immovable along the axis line, a biasing member that presses the movable sheave in a direction toward the fixed sheave, a main torque-cam mechanism that presses the movable sheave in the axis line in accordance with a relative difference in a rotational angle between the spider and the movable sheave, and a sub torque-cam mechanism that presses the movable sheave in the axis line in accordance with a relative difference in a rotational angle between the fixed sheave and the movable sheave. | 01-30-2014 |
