Abstract
A work vehicle multi-coupler assembly having a controlled breakaway feature include a pair of coupling elements that mate along a coupling axis. A shear pin is carried by one of the coupling elements. A coupler mechanism connected to the second coupling element and configured to engage the shear pin to bring the first coupling element into mating engagement with the second coupling element. The coupler mechanism is configured to shear the shear pin to permit movement of the first coupling element away from the second coupling element along the coupling axis during a breakaway event.

A multi-coupler assembly, comprising:
- a first coupling element including a first bank of fluid connectors;
- a second coupling element configured to mate with the first coupling element along a coupling axis, the second coupling element including a second bank of fluid connectors configured to couple with the first bank of fluid connectors;
- a shear pin on the first coupling element;
- and
- a coupler mechanism connected to the second coupling element and configured to engage the shear pin to bring the first and second banks of fluid couplers together when the assembly is in a coupled position;
- wherein the coupler mechanism is configured to shear the shear pin to permit movement of the first coupling element away from the second coupling element along the coupling axis during a breakaway event.
A multi-coupler assembly for a work vehicle and implement coupling arrangement, the assembly comprising:
- a first coupling element that has a first bank of fluid connectors in continuous fluid communication with the implement;
- a tether connected with the first coupling element and with the implement and configured to exert a pull force on the first coupling element during a breakaway event;
- a second coupling element that is fixed to the work vehicle and that has a second bank of fluid connectors in continuous fluid communication with the work vehicle, the second coupling element configured to mate with the first coupling element along a coupling axis to place the first bank of fluid connectors in fluid communication with the second bank of fluid connectors;
- a shear pin fixed to the first coupling element;
- and
- a coupler mechanism carried by the second coupling element and configured to engage the shear pin to bring the first coupling element into mating engagement with the second coupling element;
- wherein during the breakaway event the coupler mechanism is configured to shear the shear pin to move the second coupling element along the coupling axis and with the work vehicle away from the first coupling element and the implement, while the coupler mechanism remains stationary relative to the second coupling element.
A multi-coupler assembly for a work vehicle and implement coupling arrangement, the assembly comprising:
- a first coupling element that has a first bank of fluid connectors in continuous fluid communication with the implement;
- a tether connected with the first coupling element and with the implement;
- a second coupling element that is fixed to the work vehicle and that has a second bank of fluid connectors in continuous fluid communication with the work vehicle, the second coupling element configured to mate with the first coupling element along a coupling axis to place the first bank of fluid connectors in fluid communication with the second bank of fluid connectors;
- a shear pin fixed to the first coupling element;
- and
- a coupler mechanism carried by the second coupling element and configured to engage the shear pin to bring the first coupling element into mating engagement with the second coupling element, wherein the coupler mechanism includes a cam slot in which the shear pin is disposed when the first and second coupling elements are coupled together, wherein the cam slot has an open end and a closed end with a segment adjacent the closed end that is disposed to extend in a direction substantially perpendicular to the coupling axis;
- wherein during a breakaway event the coupler mechanism is configured to shear the shear pin to move the second coupling element along the coupling axis and with the work vehicle away from the first coupling element and the implement, while the coupler mechanism remains stationary relative to the second coupling element.
