Summary: | The invention discloses a power shift tractor axle box hydraulic system. The power shift tractor axle box hydraulic system is characterized in that a lifting system oil pump and filtering system is connected with a lubricating loop and a power shift control loop; the power gear shifting control loop is connected with the AMT auxiliary box control loop and the rear axle and PTO control loop. The lubricating loop is used for lubricating a power gear shifting gearbox in the power gear shifting control loop, an AMT auxiliary box and a rear axle in the AMT auxiliary box control loop, and a wet clutch, a bearing, a gear and a spline in the PTO control loop; the power gear shifting control loop provides system pressure and controls the power gear shifting clutch and the four-wheel drive clutch to form gears. The AMT auxiliary box control loop controls a synchronizer in an AMT auxiliary box to achieve gear shifting operation and controls a gear climbing synchronizer to achieve gear climbing. The rear axle and PTO con |
