Abstract
A method for power transmission method includes providing first and second shafts, first and second gear assemblies between the first and second shafts, and first and second coupling assemblies. The first coupling assembly coupling the first shaft to the first gear assembly, and the second coupling assembly coupling the first shaft to the second gear assembly. The speed of the first shaft varies, wherein the deployment of a locking element of the second coupling assembly is based on the speed of the first shaft.
Claims20
A power transmission method comprising:
- providing a first shaft, the first shaft rotatable at a variable rotation speed;
- providing a second shaft, the second shaft rotatable at a variable rotation speed;
- providing a first gear assembly between the first shaft and the second shaft, the first gear assembly including a gear rotatably mounted to the first shaft;
- providing a second gear assembly between the first shaft and the second shaft, the second gear assembly including a gear rotatably mounted to the first shaft;
- providing a first coupling assembly selectively coupling the gear of the first gear assembly to the first shaft, the first coupling assembly including a notch plate, a pocket plate, and a locking element in a deployed position;
- providing a second coupling assembly selectively coupling the gear of the second gear assembly to the first shaft, the second coupling assembly including a notch plate, a pocket plate, and a locking element movable between a deployed and nondeployed position;
- and
- varying the speed of the first shaft, wherein deployment of the locking element of the second coupling assembly is based on the speed of the first shaft.
