Abstract
A power transmission device may include a first power transmission unit configured to connect to an input portion and to receive a power from the input portion, a second power transmission unit configured to deliver the power to an output portion, and a connecting unit configured to connect the first power transmission unit and the second power transmission unit, and to deliver a pressure of a transfer fluid occurring due to the first power transmission unit to the second power transmission unit.
Claims16
A power transmission device comprising:
- a first transmission configured to receive a power from an input device;
- a second transmission configured to deliver the power to an output device;
- and
- an interface configured to transport a transfer agent between the first transmission and the second transmission such that a pressure associated with the transfer agent varies based on the power, wherein
- at least one of the first transmission and the second transmission includes a cylinder body having the transfer agent therein, the cylinder body including a first cylinder body and a second cylinder body, a pressure rod configured to move in a lengthwise direction of the cylinder body to press the transfer agent, and a diaphragm configured to partition an inner space of the cylinder body and to prevent the transfer agent from contacting the pressure rod;
- and
- the second cylinder body is configured to couple with the first cylinder body such that the second cylinder body wraps around a portion of an outer surface of the first cylinder body such that a side portion of the diaphragm is between the first cylinder body and the second cylinder body.
A power transmission device comprising:
- a first transmission configured to receive a power from an input device;
- a second transmission configured to deliver the power to an output device;
- an interface configured to transport a transfer agent between the first transmission and the second transmission such that a pressure associated with the transfer agent varies based on the power;
- an output power converter configured to convert a linear power from the second transmission to a rotary power, and deliver the rotary power to the output device;
- and
- an output controller configured to adjust a magnitude of the rotary power delivered from the output power converter to the output device.
