TWO-MODE COUPLING Russian patent published in 2017 - IPC F16D47/04 F16D41/04 F16D11/00 F16D15/00 F16D43/04 

FIELD: mechanical engineering.

SUBSTANCE: invention is relevant to mechanical engineering, and more specifically to clutch couplings of kinematic mechanisms. Two-mode coupling includes frequency-dependent device (FDD) for switching and safety devices that include internal and external fixtures, separator and rolling elements. Internal fixture (1) is provided with slots (12); each of them includes tangentially located surface and groove made on this surface (13). External fixture (2) includes counter-bore (1). Rolling elements (4) are placed one-by-one in each groove (13). Separator (3) is manufactured in such form, when rolling elements (4) protrude in direction of radial periphery of internal fixture (1). Internal fixture (1) can be manufactured as one that is stationary connected to driving link of switched mechanism, and external fixture (2) can be manufactured as one that is connected to driven link of switched mechanism. FDD is formed by force of wedge-like cavities of coupling, separator 3, as well as rolling elements 4, which are placed within interval between grooves 13 of slots 12 and radial surface of counter-bore 10 of external fixture 2. Coupling fixture manufactured as suitable one for axial movement forms safety device.

EFFECT: opportunity of transmission of increased torques is achieved.
