Patent application number | Title | Published |
20140349805 | Continuously Variable Transmission Provided with a Roller Parking Zone - Generally stated, various embodiments described herein concern a toroidal CVT provided with parking zones where the rollers are brought when the CVT is powered down. More specifically, a portion of the toroidal surfaces of the disks is reserved as a parking zone therefore preventing premature wear and/or damages to the working portion of the disks. | 11-27-2014 |
20140311831 | DISK SHAPED LUBRICATING FLUID DISPENSER - A disk shaped lubricating fluid dispenser to dispense lubricating fluid on rotating disks requiring film lubrication is described. The various embodiments provide a relatively constant and uniform 360-degree coverage of lubricating fluid on a rotating disk via a plurality of diffusing pins. | 10-23-2014 |
20140257655 | OVER CLAMPING PROTECTION METHOD AND CLAMPING MECHANISM THEREFOR - A method where the spin factor is looked up in a table; the slip factor is measured and the clamping pressure is adjusted to achieve a slip/spin ratio provided in a desired range is described herein. According to another aspect, an active mechanical clamping mechanism using a longitudinally movable contact point is also described. | 09-11-2014 |
20140243147 | Continuously Variable Transmission (CVT) Having a Coaxial Input/Output Arrangement and Reduced Friction Losses - A toroidal Continuously Variable Transmission provided with co-axial input/output arrangement where a drum assembly is used to transfer torque from a central driven disk of the CVT to the input or output shaft thereof. The drum assembly includes features to reduce the friction between the rotating drum and lubrication fluid present in the transmission. | 08-28-2014 |
20140155220 | Drivetrain Provided with a CVT - A drivetrain provided with a CVT that can be used in both CVT and Infinitely Variable Transmission (IVT) configurations and that includes a high-low gear selection assembly and a power mixer is described herein. The drivetrain includes a high-low gear selection mechanism that provides, in combination with the CVT, high and low ranges of gear ratios. The drivetrain further includes a power-mixer that allows the IVT configuration for transitions between high and low configurations that are seamless to the operator. | 06-05-2014 |
20140045637 | DRIVETRAIN PROVIDED WITH A CVT - A compact drivetrain provided with a CVT that can be used in CVT low and high configurations and in a reverse configuration is described herein. In addition to the CVT, the drivetrain includes first and second planetary gear trains compactly mounted in series so as to selectively cooperate with the CVT and a configuration selection system coupled to both first and second planetary gear trains and to the output disk of the CVT for selectively associating the output shaft of the drivetrain to the outputs of the first and second planetary gear trains or to the output disk of the CVT for allowing the three modes of operation. | 02-13-2014 |
20130210574 | Drive Train Provided with a CVT - A drive train provided with a CVT that can be used in both CVT and Infinitely Variable Transmission (IVT) configurations and that include a High-Low gear selection assembly is described herein. Transitions between configurations are seamless to the operator. | 08-15-2013 |
20130116084 | Pressure Applying Mechanism for Toric-Drive Transmission - A pressure applying mechanism for a toric-drive Continuously Variable Transmission (CVT) that comprises two opposed elements each with internal V-shaped ramp surfaces and at least three ball bearings interposed between the elements wherein rotation of one element causes the mechanism to expand in the longitudinal direction and thus generate an appropriate pressure between a drive disk and a driven disk. The invention further includes a pre-load mechanism comprising a washer for adjusting the pre-load on the pressure applying mechanism. | 05-09-2013 |
