FREEWHEELING CLUTCH, TORQUE HYDROCONVERTER WITH TWO COUPLINGS AND MACHINE COMPRISING SAID ELEMENTS Russian patent published in 2021 - IPC F16D41/12 F16H41/00 B60K17/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to freewheeling clutch, a torque hydroconverter with two couplings and machine containing said elements. The freewheeling clutch (1) comprises a first rotatable component (10) and a second rotatable component (20). The first component (10) comprises an outer edge (12) provided with ratchet teeth (11) and the second component comprises a ratchet pawl (21). The freewheeling clutch comprises a mechanism for preventing contact, which forces the ratchet pawl (21) in a separation mode, overcoming the displacement force applied thereon and preventing the ratchet pawl from coming into contact with the outer edge (12) and the ratchet teeth (11). The contact prevention mechanism comprises an electromagnet (24) embodied on the second component (20). The electromagnet, when the voltage is applied to it, pulls the ratchet pawl (21) and pushes the ratchet dog from the outer edge (12) of the first component (10) and the ratchet teeth (11). The induction coil (25) is connected to an electromagnet (24). The magnetic field pole for generating the magnetic field is formed on the first component (10). The induction coil (25) crosses the magnetic induction lines and excites the electromagnet (24) when the first and second components rotate relative to each other in the separation mode.

EFFECT: reduction in friction losses.
