FIELD: transport.
SUBSTANCE: invention relates to use of viscous coupling for automatic gear shifting. In the bushing of front wheel, case bushing (23) rotating movable bushing of viscous coupling is fixed. Front wheel bushing also rotates control link connected by flexible connections with movable bushing of viscous coupling via group of rollers (22) of case bushing (23). When speed changes the tension of flexible connections changes proportionally providing control link shift and connection of force via cable for rear gear shifter operation.
EFFECT: providing smooth bending of flexible links, and in case of imbalance of equilibrium of control link - reduction of friction in bend area which improves accuracy of switching and reliability.
