Abstract
An overload clutch wherein a clutch hub and a clutch sleeve are brought into and out of driving engagement by spring loaded driving members in the hub engaging into recesses in the sleeve. The disengagement of the clutch is achieved in stages by constructing the recesses so that the driving members will disengage individually at different torque transmission levels. More specifically, the depth of the recesses is varied to vary the disengagement levels of the driving members.
Claims10
An overload clutch particularly for drive lines connecting agricultural implements to a power takeoff shaft of a tractor comprising:
- a clutch hub;
- a clutch sleeve;
- a plurality of recesses in said clutch sleeve;
- and a plurality of spring-loaded driving members mounted in said clutch hub to engage and disengage said recesses to effect engagement and disengagement of said clutch;
- said recesses and said driving members being configured to effect disengagement of certain individual ones of said plurality of driving members at different torque transmission levels than remaining driving members of said plurality of driving members.
An overload clutch particularly for drive lines connecting agricultural implements to a power takeoff shaft of a tractor comprising:
- a driven member;
- a driving member;
- a plurality of recesses in one of said driving and driven members;
- and a plurality of spring-loaded driving members mounted in the other of said driving and driven members to engage and disengage said recesses to effect engagement and disengagement of said clutch;
- said recesses and said driving members being configured to effect disengagement of individual ones of said plurality of driving members at different torque transmitting levels than the other driving members of said plurality.
An overload clutch particularly for drive lines connecting agricultural implements to a power takeoff shaft of a tractor comprising:
- a driven member;
- a driving member;
- a plurality of recesses in one of said driving and driven members;
- and a plurality of spring-loaded driving members mounted in the other of said driving and driven members to engage and disengage said recesses to effect engagement and disengagement of said clutch;
- said recesses and said driving members being configured to effect disengagement of individual ones of said plurality of driving members at different torque transmitting levels than remaining driving members of said plurality of driving members;
- said recesses and said driving members being configured so that the engaging surfaces therebetween are formed with differing angles for different driving members and recesses.
An overload clutch particularly for drive lines connecting agricultural implements to a power takeoff shaft of a tractor comprising:
- a driven member;
- a driving member;
- a plurality of recesses in one of said driving and driven members;
- and a plurality of spring-loaded driving members mounted in the other of said driving and driven members to engage and disengage said recesses to effect engagement and disengagement of said clutch;
- said recesses and said driving members being configured to effect disengagement of individual ones of said plurality of driving members at different torque transmitting levels than remaining driving members of said plurality of driving members;
- said driving members and said recesses having facing abutting surfaces at which said driving members engage in said recesses to drive said clutch, said facing abutting surfaces of at least one of said recesses having a different slope or inclination than the other of said recesses.
