Embodiment Construction
[0008] as attached figure 1 As shown, the planetary gear train of the present invention is formed by the sun gear 1 , the planetary gear 2 , the sun gear 3 and the member 4 . One of the hydraulic motors 6 meshes with the center wheel 1 through one of the gears 5; the other hydraulic motor 6 meshes with the sun gear 3 through the other gear 5, so the power of the two hydraulic motors 6 is respectively The input is on the center wheel 1 and the sun wheel 3, and the flows of the two hydraulic motors 6 are respectively controlled by the two proportional speed regulating valves 7, which forms the power input system of the present invention. In order to balance the centrifugal inertial force generated by the planetary gears and reduce the force of the planetary gears, six planetary gears 2 are symmetrically distributed between the center gear 1 and the sun gear 3 . Each end of the six connecting shafts 7 is respectively fixed to the central shafts of the six planetary wheels 2; eac...
