<p>PROBLEM TO BE SOLVED: To provide a power transmission mechanism of an auxiliary machine, capable of improving the fuel economy of a vehicle, decreasing restriction on a layout, and saving a space, by taking out the output of an internal combustion engine when the auxiliary machine requires and accurately driving the auxiliary machine at engine speed which makes the operation efficiency of the auxiliary machine good; and a power transmission method of the auxiliary machine.SOLUTION: A working fluid discharged from a first fluid pump 12A and a second fluid pump 12B connected to an internal combustion engine 10 through a power disconnecting device 16 and driven by the power of the internal combustion engine 10, is made to flow through a fluid motor 14 for driving au auxiliary machine 20, thereby driving the auxiliary machine 20 with the power of the internal combustion engine 10. Connection and disconnection of the power disconnecting device 16 is controlled on the basis of engine speed Ne of the internal combustion engine 10. All of the working fluid discharged from the first fluid pump 12A is made to pass through the fluid motor 14 and return to the first fluid pump 12A. By distributing a flow rate of the working fluid discharged from the second fluid pump 12B, a flow rate passing through the fluid motor 14, and a flow rate which does not pass through the fluid motor 14 are adjusted by a flow rate distribution valve 13 while including zero, and returned to the second fluid pump 12B.</p> |
