Embodiment:
The improvement project of the double speed low speed wheel hub motor of embodiment one: NGW type planet circular system
With reference to Fig. 2, Fig. 3, Fig. 4 and Fig. 5, one-way clutch, also known as freewheel clutch, has various structures, and for the sake of simplicity, getting Ratcheting one-way clutch is example.Fig. 3, Fig. 4, Fig. 5 take out two one-way clutch groups in Fig. 2, and described specially, wherein Fig. 3 is front view, and Fig. 4 is A-A profile, and Fig. 5 is B-B profile.Unified in order to describe, assuming that forward driving-chain is high-speed drive, reverse drive chain is low speed rotation.In figure, high-speed drive is inputted by high speed ratchet 6.2, and be also forward driving member, low speed rotation is inputted by low speed ratchet 6.1, is also reverse drive part; Namely clutch base 6, as the output of motor-driven, also exports driving member, is directly connected by screw threads for fastening with wheel hub.Clutch base 6, when vehicle backing and hypervelocity, is again the input of wheel movement.
When motor rotates forward, Movement transmit is to high speed ratchet 6.2, then promote by the ratchet 11 of spring 13 jack-up, drive pawl base 7 to rotate, also namely described spacer shell, the inner ring of this pawl base 7 is jagged, also be circumferential breach, it be equipped with elastic buffering pad 10, after one section of idle running, this elastic buffering pad 10 just contacts with the link stopper 12 on clutch base 6, then promotes clutch base 6 output motion.Utilize the additional movement that in engaging process, its idle running produces, the attached transmission mechanism that pawl base 7 is equipped with--cam 8 depresses the controlled ratchet 9 that clutch base 6 is installed, and has cut off whole transmissions of low speed one-way clutch.Otherwise circumferential breach is opened in clutch base 6 side, and link stopper 12 is fixed on pawl base 7 side, can reach effects equivalent.
During motor reversal, oppositely drive high speed ratchet 6.2 to rotate, drive ratchet 11 by frictional force, affect pawl base 7 clutch base 6 counter motion relatively, cam 8 decontrols controlled ratchet 9, and under the effect of another spring 13, controlled ratchet 9 recovers normal function; The low speed ratchet 6.1 that moves through now after deceleration is also reverse inputs, and drives clutch base 6 to export low-speed motion by controlled ratchet 9.
During vehicle sliding, two one-way clutch all skid, and do not transmit motion.
When vehicle is pushed reversing, return motion inputs from one-way clutch seat 6, the inverse process that similar motor rotates forward, reverse drive chain has been cut off in the additional movement produced by idle running, upside-down motion only passes to rotor by high speed ratchet, and dragging motor dallies, and can not form self-locking.
Compare before this Structure and improvement, not only solve the self-locking problem that falls back, and when the top gear that vehicle the most often uses runs, eliminate low speed ratchet 6.1 reversion and produce with controlled ratchet 9, clutch base 6 and spring 13 problem rubbing, collide each other, both reduced wear, again reduce noise, also improve overall efficiency.In driving conditions during gear shift, due to the effect of cushion pad, low speed switches impact when going high speed, vibrations, noise decline to a great extent, and also effectively extend the life-span of clutch.When falling back, be low speed rotation chain due to what cut off, the reversing resistance ratios common reduction box motor caused due to magnetic resistance of motor Buddhist nun is little.
Further enforcement: other structure of double speed low speed wheel hub motor improvement project-
Pawl base 7 in above-mentioned representative instance, elastic buffering pad 10, link stopper 12 constitute additional lost motion mechanism jointly with clutch base 6; Be contained in the cam 8 on pawl base 7 and controlled ratchet 9, jointly form attached transmission mechanism; Controlled ratchet 9, low speed ratchet 6.1 and clutch base 6 be composition controllable one-way clutch device jointly.This three cover mechanism and mutual relation thereof, be marrow of the present invention, change on this basis and be not difficult, because can there be numerous combination in this each mechanism to concrete each mechanism.
Such as additional lost motion mechanism can also be volume-varying structures or by elastomeric material, pawl base and clutch base is connected into, and even can be made into one with elastomeric material by difformity; The formation of attached transmission mechanism is just more, as lever drive can be used instead, liquid moulds transmission, steel ball transmission, screw-driven, inclined-plane transmission etc.; Controllable one-way clutch device also can select steel ball friction-type, roller friction-type, needle roller friction-type, distortion cover, distortion dish-type, contract block formula etc.Various change mainly will be accustomed to according to respective technique, ability and alap cost, the supporting level etc. of relevant enterprise.
