Only face.
Two pairs of planetary gears and a pair of axle shaft gears are provided with differential carrier, two pairs of planetary gears are arranged in cross,
Y-axis and z-axis are located at respectively, and two pairs of planetary axles use the rotating shaft of cross axle, axle shaft gear to be located at x-axis, axle shaft gear
Be fixed together synchronous axial system with its rotating shaft, an axle shaft gear by driving planetary gear rotation, so as to be transferred to another
Axle shaft gear is rotated.
Thrust bearing includes seat ring, blowout patche, and is clipped in retainer and rolling element therebetween, and rolling element is arranged on to be protected
Hold in the space of frame.
Thrust bearing uses needle roller thrust bearing, i.e. rolling element for needle roller, and the central shaft of needle roller is located at the radius of the bearing
Direction.
The retainer of thrust bearing is provided with centre circle big groove, outer ring little groove and inner ring little groove, makes the axle of retainer
Section forms W shapes, is provided for separating the space of rolling element at centre circle big groove, and outer ring little groove and inner ring little groove are used to increase
Reinforcement degree.
The two sides of the blowout patche of thrust bearing is plane, and the lower surface of seat ring is plane, upper surface is provided with sphere, blowout patche edge
