2. the radial type hillside tractor according to claim 1 with cascaded structure power speed changing system, feature exist
It is in the drive mechanism of the power speed changing system：For the input shaft of high-power case by the direct-connected power of clutch, high-power case will
Power on its input shaft is divided into two：The input shaft of the one high-power case of routing enters end tooth wheel set, outlet gear pair, nipper pair
The drive mechanism speed change of composition is exported by preceding line shaft, power output shaft, provides power needed for farm implements；Another way active force flow
The output gear of input tooth engagement by the input tooth and connection tooth that are installed on high-power case input shaft, gear teeth and connection tooth is nibbled
It closes, the kinetic current after speed change is transferred to speed change output shaft and inputs header box by the gear teeth, by being fixedly mounted with power taking thereon
The sun gear that gear pair drive is installed on power taking axis rotates, and kinetic current passes to gear ring by the planetary gear in planetary gear train, with
The motor tooth engagement confluence being installed on hydrostatic transmission or motor output shaft, realizes the efficiently dynamic of radial type hillside tractor
Power variable speed.
3. the radial type hillside tractor according to claim 1 or 2 with cascaded structure power speed changing system, feature
It is：The hydrostatic transmission or motor provide power by mating hydraulic system, and the kinetic current of output is imported through motor gear
The outer increment of planetary gear train gear ring, two strands of kinetic currents collected influence each other the output speed of gear ring, big by gear ring, differential
Tooth, differential mechanism, inter-axle differential pass through front axle, the front/rear output of rear axle；The front axle is by the way that the cone tooth being fixedly mounted with it is secondary, main bridge
Kinetic current is transferred to main bridge semiaxis by differential mechanism, and the rear axle provides the rear axle power of supporting chassis.
