CENTRIFUGAL STEPLESS TRANSMISSION Russian patent published in 2000 - IPC

FIELD: mechanical engineering. SUBSTANCE: transmission is shaped as a centrifugal clutch. It has units of generation and transformation and rectification of pulses. Pulse generation and transformation unit includes the first half-clutch with sealed cavity and the second half-clutch positioned coaxially. Hydraulic resistors are located in peripheral part of sealed cavity. Pulse rectification unit contains overrunning clutch connected rigidly to the second half-clutch. Overrunning clutch may be connected to power consumer through flexible coupling. Hydraulic resistors are made of working blades mounted on the first half-clutch for rotation. Each of blades is coupled to the second half-clutch by gear transmission. Sealed cavity may be irregularly shaped. It may consist of sectors, edges of each sector corresponding to curves described by ends of rotating working blades. Sealed cavity is filled with working fluid to at least points of overlapping of sector edges. Blades are connected rigidly to gears engaged with central gear connected rigidly to the second half-clutch. Weights mounted on axle of rotation of blades for free rolling are suspended from pendulum holder. Blades are made integral with balancing parts positioned opposite to their working parts. Overrunning clutch may be coupled to power consumer by means of flexible coupling through flywheel. Flexible coupling is made of one or several Archimedean spirals. One of ends of every spiral is coupled to external casing of overrunning clutch and other, to flywheel. Flexible coupling may also comprise at least two discs with arched slots. EFFECT: higher wear resistance. 13 cl, 11 dwg
