Abstract:
A system for providing hydraulic power in a machine transmission includes a first hydraulic variator and a second hydraulic variator, each variator having a mechanical input to a hydraulic pump, and a hydraulic motor linked to the hydraulic pump via a hydraulic circuit, and a mechanical output from the hydraulic motor. In an embodiment, the first hydraulic circuit side of one variator is hydraulically connected to the first hydraulic side of the other variator, and the second hydraulic circuit sides are likewise linked together. A common input is geared to the inputs of the variators and a common output is geared to the outputs of the variators, tying the pump and motor of each variator to rotate at the same speed as the counterpart components of the other variator.
