Structure and method for simultaneously supplying oil to two friction clutches

The invention discloses a structure and an oil supply method for simultaneously supplying oil to two friction clutches, relates to an oil supply structure and an oil supply method for friction clutches, and aims to realize the purposes of simultaneously controlling the two friction clutches, improving the compactness and rationality of a gear transmission device, saving space and reducing the weight of a gear transmission system. The oil inlet shaft is rotationally connected and installed in the clutch oil inlet seat, the friction clutch pressure oil inlet ring is inserted into the clutch oil inlet seat, the first oil inlet connector and the second oil inlet connector are communicated with the clutch oil inlet seat, and an oil return through hole is machined in the clutch oil inlet seat. A first friction clutch pressure oil supply port, a second friction clutch pressure oil supply port and a friction clutch lubricating oil inlet are machined in the oil inlet shaft. The method comprises the steps that firstly,
