MULTIPLE DISK VARIABLE-SPEED DRIVE Russian patent published in 1999 - IPC

FIELD: mechanical engineering, applicable for progressive transmission of motor vehicle. SUBSTANCE: multiple disk variable-speed drive comprises: central wheels, carrier, intermediate disks, internal and external beaded disks, pressure- adjusting devices with flexible members of axial action and tie. The flexible members of all beaded disks are located on both end-face sides of all intermediate disks and are engageable with the end faces of all beaded disks. The mean axial rigidity of the flexible members for the external beaded disks is higher in its absolute value than that for the internal beaded disks. The above flexible members can vary the axial rigidity in value and sign. The pressure - adjusting devices for adjustment of pressure force may have weights or sealed chambers connected to a fluid medium source under pressure. EFFECT: simplified construction and enhanced efficiency. 5 cl
