Abstract
A clutch particularly suitable for machine drives in agricultural implements including a clutch hub, a clutch sleeve, and spring-loaded dog members operative to engage and disengage within tapered recesses in said clutch sleeve for controlling torque transmission through the clutch. The recesses are formed with a circumferential dimension large enough to accommodate therein movable control members together with engagement heads of the dog members. The control members cooperate with the dog members within the recesses to effect disengagement of the clutch when a maximum torque is exceeded and to automatically effect re-engagement of the clutch upon achievement of a nominal speed whereupon the dog members, which are spring-loaded in the clutch hub, may automatically re-engage within the recesses.
Claims7
A clutch for machine drives particularly suitable for agricultural implements comprising a clutch hub, a clutch sleeve, tapered recesses in said clutch sleeve, and spring loaded dog members having wedged engagement heads with a flattened face for engagement in said recesses for transmitting torque between said hub and said sleeve, said recesses having a circumferential dimension larger than the circumferential dimension of said wedged engagement heads of said dog members such that when said dog members are in torque transmitting position within said recesses, a remaining space is provided which is occupied by movable control strips and such that when said dog members are not engaged in torque transmitting position within said recesses the distance of movement of said control strips in the circumferential direction is equal to or smaller than the head width of said flattened face.
A clutch for machine drives particularly suitable for agricultural implements comprising a clutch hub, a clutch sleeve, tapered recesses in said clutch sleeve and spring-loaded dog members having wedged engagement heads for engagement in said recesses for transmitting torque between said hub and said sleeve, said recesses being dimensioned in the circumferential direction thereof to provide therein space for accommodating said engagement heads of said dog members and control strips, said control strips being accommodated within said recesses and configured to cooperate with said engagement heads and said recesses such that said clutch will disengage when a predetermined maximum torque is transmitted therethrough, said control strips, said dog members, and said recesses operating cooperatively to automatically effect re-engagement of said clutch at a predetermined nominal speed.
