Abstract
A safety clutch for an agricultural vehicle includes a driven rotational element having a recess and a roller configured to be received in the recess. The roller is configured to move between positions depending on the relative torque between the roller and the driven rotational element such that the roller either drives rotation of the driven rotational element or does not. An actuator moves the position of the roller.
Claims18
A safety clutch for an agricultural vehicle, said safety clutch comprising:
- (i) a driven rotational element comprising a recess;
- (ii) a roller configured to be received in the recess of the driven rotational element;
- (iii) a biasing unit configured to urge the roller into the recess with a biasing force, wherein the roller is configured to move between:
- a first position in which the roller is seated in the recess of the driven rotational element to drive the driven rotational element to rotate;
- and
- a second position in which the roller is unseated from the recess of the driven rotational element, and
- (iv) an actuator having a moveable end that is positioned against the roller and is operable to move the roller from the first position to the second position in response to an override input;
- wherein the roller is configured to move between the first position and second position in response to:
- (a) a relative torque between the roller and the driven rotational element overcoming the biasing force;
- and
- (b) the actuator moving the roller in response to the override input, wherein the override input is independent of the relative torque.

In a safety clutch for an agricultural vehicle, said safety clutch comprising:
- (i) a driven rotational element comprising a recess;
- (ii) a roller configured to be received in the recess of the driven rotational element;
- (iii) a biasing unit configured to urge the roller into the recess with a biasing force, wherein the roller is configured to move between:
- a first position in which the roller is seated in the recess of the driven rotational element to drive the driven rotational element to rotate;
- and a second position in which the roller is unseated from the recess of the driven rotational element, and (iv) an actuator having a moveable end that is positioned against the roller and is operable to move the roller from the first position to the second position in response to an override input, a method of operating the safety clutch comprises:
- actuating the actuator to move the roller from the first position to the second position in response to:
- (a) a relative torque between the roller and the driven rotational element overcoming the biasing force;
- and (b) the actuator moving the roller in response to the override input, wherein the override input is independent of the relative torque.
