Overrunning clutch of a freewheeling clutch

摘要

The annular surface 18 of the outer oscillating drive member 19 of a freewheeling clutch is connected to the cylindrical surface 20 of the shaft 21 is accommodated. The ring 22 carries the connecting rod 23 with the dog 24. in the case of movement looked according to the right rotates the coupling member 25 of the drive system the outside oscillating drive member 19 on the basis of the jamming of the annular surface 18 on the cylindrical surface 20, together with the shaft 21 in the clockwise direction. The for transmission of the torque from the in the circle of radius r acting drive force z sufficient clamping forces k ′, k "of the annular surface 18 to the cylindrical surface 20, because of the axial distance a between the annular surface 18 and the remote surface 26 of the end face of the driver 24, it can be achieved. In the case of movement to the left looked rotates the coupling member 25 of the drive system the outside oscillating drive member 19 through the action of the compressive force s of the proximal face 27 of the coupling member 25 against the counterclockwise direction without a shaft 21, since the remote surface 26 of the end face of the driver 24 the reversal at an angle position of the ring 22 prevent. In addition, the axial distance "a " between the annular surface 18 and the proximal face 27 of the coupling member 25 not sufficient, the clamping forces is important to produce.
