Abstract
The automatic speed changing system is composed of following parts: outer shell of wheel hub, stator, sun gear, shaft of one-way clutch, planet wheels, gear ring, electromagnetic brake, and moving plates of electromagnetic brake etc. When current in different direction is applied to electrical motor, co-rotation and reverse rotation of motor drives the automatic speed changing system so as to reach purpose of changing speed, and moment. But, outputting direction of rotation is always in same direction.
Description
The present invention is a kind of electromechanics formula automatic transimission, especially can make motor obtain different big or small torque and rotating speeds when forward and backward, and output turns to all the time in the same direction.
At present, the used speed change gear of motor has two kinds, a kind of is the stepless controller speed change of electronic type, this gear shift mode can obtain from 0 maximum speed to motor, good speed change curve is arranged, but the level of torque that it is exported is directly consistent with the input current size variation of motor, and (when voltage is constant) just the big more electric current of motor load is also big more; Another kind is the mechanical type gear shift mode, this gear shift mode, it can be the step speed change formula, it also can be stepless speed change type, the mechanical type gear shift mode, more topmost is the output torque that can obtain different sizes, just when output current is constant, by the mechanical type deceleration energy torque is increased, perhaps torque is reduced during speedup.
The purpose of this invention is to provide a kind of wheel-hub motor planetary automatic speed-changing system, realize dynamic auto speed change, the bending moment of motor, and output turns to constant.
The object of the present invention is achieved like this, motor output shaft connects the sun gear of a planetary reduction gear earlier, connect the rotating shaft of an one-way clutch again, the body and the planet carrier of one-way clutch are connected as a single entity, on the one-way clutch body, be connected with the moving plate of an electromagnetic brake simultaneously, reach the self-shifting purpose by the clutch that turns to (forward and backward) and electromagnetic brake of controlling motor.When motor turn to forward the time, power passes to planet carrier by one-way clutch, because the rotating shaft of sun gear and one-way clutch is connected as a single entity, so in fact whole planetary transmission system is dead by unidirectional clutch lock when forward, make whole planetary system become a connector, power is passed on the wheel hub.When motor reverses, one-way clutch is untied, electromagnetic brake work is locked with the moving plate that is connected in the electromagnetic brake on the one-way clutch body simultaneously, because one-way clutch body and planet carrier are connected as a single entity, be actually that planet carrier is locked, at this moment power is to pass to planetary gear by sun gear, arrives gear ring again to the wheel hub motor shell, planetary reduction systems work, at this moment outputting power takes turns hub shell all the time by original rotation direction rotation.
Concrete structure of the present invention is provided by following examples and accompanying drawing:
Fig. 1, be primary structure schematic diagram of the present invention
Among Fig. 1,1, the wheel hub shell, 2, motor stator, 3, the rotor shell, 4, sun gear, 5, the one-way clutch rotating shaft, 6, planet carrier, 7, planetary gear, 8, gear ring, 9, the one-way clutch body, 10, the electromagnetic brake moving plate, 11, electromagnetic brake.
Detail and working condition below in conjunction with Fig. 1, detailed description the present invention proposition.
The present invention includes wheel hub shell (1), inside a motor stator (2) is arranged, there is rotor shell (3) the motor stator outside, rotor shell (3) is connected with the sun gear (4) of planetary mechanism, and be connected with one-way clutch rotating shaft (5), one-way clutch body (9) is connected as a single entity with planet carrier (6) simultaneously, be connected with electromagnetic brake (10) on the one-way clutch body (9), electromagnetic brake moving plate (11) is connected as a single entity with motor stator axle (12), and gear ring (8) is connected with wheel hub shell (1).
The present invention is work like this, when motor stator (2) energising and polarity are when making motor steering be forward, rotor case (3) forward rotation, power is transferred on the sun gear (4), also pass in the one-way clutch rotating shaft (5) simultaneously, be forward because turn to, so one-way clutch body (9) is to be in locking state with one-way clutch rotating shaft (5).In addition, again because sun gear (4) and (6) two moving cells of planet carrier of epicyclic transmission mechanism are dead by unidirectional clutch lock, power is actual to be directly to pass on the wheel hub shell (1) by planetary reduction systems, and (planetary system is work not, only plays an anastomosis.) realized the direct output of motor power.
Behind the electricity of the logical upward opposite polarity of motor stator (2), motor steering is with original opposite, the power of rotor (3) passes in sun gear (4) and the one-way clutch rotating shaft (5), because turn to oppositely, one-way clutch rotating shaft (5) and one-way clutch body (9) just are in the state of untiing.Electromagnetic brake (11) work simultaneously, electromagnetic brake moving plate (10) is braked, because electromagnetic brake moving plate (10) is connected with one-way clutch body (9), and one-way clutch body (9) is an one with planet carrier (6), actual is that planet carrier is braked, at this moment power arrives gear ring (8) by sun gear (4) again to planetary gear (7), arrives wheel hub shell (1) outputting power at last.Realized forward and backward, thereby and made the wheel hub shell reach the function of speed change, bending moment all the time towards original rotation direction rotation by planetary automatic speed-changing system by motor.
