b a xPattern or " i
A-bH" pattern, thereby realize the increase and decrease output torque.
When electromagnetic device was got member b, this planet circular system ran on i
b axPattern, power are by member a input, and by member H output, its reduction ratio i=1+Zb/Za, finally export the rotary power that increases square.
When electromagnetic device is vertical while putting member b, this planet circular system conversion operation is in " i
A-bH" pattern, the braking pair in it links up member b and member H, and satellite gear stops autobiography, and power, by the input of a member, is directly exported its reduction ratio i=1 by the H member: 1, finally export the rotary power of 1: 1.
The hub-type electric wheel of internal rotor, in most times of operation, planet circular system in it all is in the drive state of deviating from that stops the rotation axis rotation, only when vehicle start, climbing or acceleration, planet circular system in it just is in the drive state of rotation axis rotation, so mechanical wear is very little with wearing and tearing.And the frequent starting of electronlmobil, the huge period of power consumption just of climbing increase the output torque in good time automatically, and electronlmobil just can easily be started to walk, accelerates, be climbed, and its power consumption does not rise counter falling, and course continuation mileage is extended.
