Cone friction clutch 1 rotates together with shaft a, sliding along its axis. Cone friction clutch 2 slides along the fixed housing. When clutch 1 is engaged to carrier H, driven shaft b rotates in the same direction as driving shaft a. When clutch 2 is engaged to carrier H, shaft b rotates in the opposite direction. When both clutches, 1 and 2, are disengaged (as shown) and a resistance torque is applied to shaft b, this shaft is stationary.
