The specific embodiment

Please refer to Fig. 1, the utility model is similar to general Electrical Bicycle basically.Different is to take down former chain gearing, sets up the full-depth tooth wheel-speed regulating change box, and output shaft of gear-box is paid the trailing wheel ratchet device with transmission shaft and bevel drive and connected.

Described connection can have two kinds of basic modes.

(1) first kind is and the electric wheel hub connecting mode.

Axis (step main shaft) is arranged in the change speed gear box, have a bevel drive to pay in the change speed gear box, vertical rotation of main shaft (plane of rotation and vehicle frame plane parallel) is paid the lateral rotation that becomes output shaft of gear-box (plane of rotation is vertical with the vehicle frame plane) by bevel drive.Output shaft is paid input shaft with long pass moving axis (or transmission shaft adds the duplex axial organ) with the back bevel drive and is connected, and back bevel drive is paid mouth and connected with trailing wheel ratchet device (also being the electric wheel hub ratchet device).

This kind connecting mode is not established mechanical adjustable speed drive, directly changes the speed of a motor vehicle by electric machine speed regulation.Its advantage is comparatively easy, and shortcoming is to alleviate motor load by mechanical speed governors according to change of topography.

(2) second kinds is the connecting mode with the middle motor driver.

Bicycle middle shaft is provided with the speed governing drop-gear box, middle motor driver output shaft (by slow down) links with double-clutch and axis and change speed gear box first gear, the final output shaft of change speed gear box is paid input shaft with long pass moving axis (or transmission shaft adds the duplex axial organ) with the trailing wheel bevel drive and is connected, and the trailing wheel bevel drive pays mouth and the trailing wheel ratchet device connects.

Above-mentioned connecting mode change speed gear box is provided with mechanical adjustable speed drive, can alleviate the load of manpower or motor because landform changes by mechanical speed governors, thereby can prolong the service life of motor and battery.But structure is complicated slightly.

The utility model is described in further detail with regard to specific embodiments and the drawings below.Present embodiment is above-mentioned second kind of connecting mode, and supporting is the product of skill Ke Mei company in Beijing, " mid-coaxial type harmonic drive motor driver "

Please refer to Fig. 1, Fig. 2, Electrical Bicycle of the present utility model comprises handle 1, electrical instrumentation dish and effector 2, front fork 3, front brake assembly 4, battery 5, front-axle beam 6, governor frame 7, change speed gear box 8, lower oblique tube 9, goes up inclined tube 10, vertical tube 11, wherein 6,7,8,9,10,11 assembly weldings constitute vehicle frame, seat cushion 12, step 13, the motor 14 of the coaxial harmonic reduction actuator of mesopore shaft type, coaxial harmonic speed reducer 15, double-action clutch 16, axis 17.

Fully-geared transmission Electrical Bicycle principle of work of the present utility model:

Please be simultaneously with reference to Fig. 3, Fig. 4, axis 17 connects by paying 27 assembly sets with double-action clutch 16 with 1# gear and bevel drive, the power-transfer clutch energising.1# gear and bevel drive are paid 27 and are fitted with motor output shaft, the power-transfer clutch outage, and under action of the spring, the 1# gear is fitted with the axis Friction disk, thereby finishes electronic and manually driven is changed.Sliding sleeve 19 is to connect with the 6# triple gear, can drive the 6# gear and slide on castellated shaft 29, and bearing pin 20 is fixed in sliding sleeve 19; With pin 21 hinged shift fork 22, sliding spring seat 23, spring 24, the fixing spring seats 25 of being equipped with, there is taper knob 26 governor frame 7 upper ends in governor frame 7; During speed governing, pull and start sleeve 26, make 23 slippages of sliding spring seat.Taper knob 26 lower end locating tips break away from the sharp groove of governor frame 7, and turning handle makes shift fork 22 drive bearing pin 20, sliding sleeve 19 and the slippage of 6# gear, thereby the engagement of change 6# gear and 3#, 4#, 5# fixed gear wheel changes speed ratio.Taper knob 26 also can be contained in Fig. 1 long and two-short dash line position in addition, drives sliding sleeve 19, bearing pin 20, the slippage of 6# gear with pull bar.2# gear wheel shaft 28 two ends are fixed on the tank wall with bearing and bearing case.Axle central authorities install bevel drive and pay 27, and its output shaft is the gear wheel shaft 18 of 3#, 4#, 5# fixed gear wheel, and two ends are fixed on tank wall and the middle crosspiece with bearing and shell.Gear wheel shaft 18 tops are that castellated shaft 29 is fixed on tank wall and the middle crosspiece with bearing 30 and bearing case.6# triple gear and sliding sleeve 19 are housed on the castellated shaft 29.Castellated shaft 29 left ends are paid input shaft 33 as mouth with duplex axial organ 31, long pass moving axis 32 and trailing wheel bevel drive and are connected.The trailing wheel bevel drive is paid and is paid input shaft 33, bearing 34, bevel pinion 35, bevel gear wheel 36, housing 37, bearing 44 by bevel drive and form.Big bevel pinion 36,35 with bearing 34,44 and axle mounting in same housing 37, as global facility assembling to guarantee transmission accuracy.Bevel gear wheel 36 is used thread connection as mouth and internal tooth ratchet 38.Internal tooth ratchet 38 and ratchet 40, pawl wheel 39 unidirectional driving coupling.Pawl wheel 39 is fixed on the wheel hub 41 with screw thread.The wheel hub two ends are that slot rolling is tightened by ball 42, packing ring 45, middle axle head axle sleeve 49 and nut 50.Then whole trailing wheel connecting shaft is packed in left end two grooves of lower oblique tube 9, tighten with nut 47, packing ring 48.

When travelling, by cabinet switch, electronic or step makes axis do vertically to rotate.Do vertically to rotate thereby drive 1# gear one 2# gear wheel shaft 28, pay 27 by bevel drive and become gear wheel shaft 18 and make lateral rotation, thereby make 6# triple gear and castellated shaft 29 make lateral rotation by predetermined speed ratios.Making bevel drive pay input shaft 33 by duplex axial organ 31, long pass moving axis 32 makes lateral rotation, by bevel gear wheel 36, internal tooth ratchet 38, ratchet 40, pawl wheel 39 wheel hub 41 is vertically rotated again.Thereby make bicycle to overtake by desired speed.
