Abstract
The utility model belongs to the electric vehicle, in particular to an electric bicycle mechanical speed variable device, which is characterized in that an adjusting handlebar is coupled with a cross shaft; a main pin shaft provided with an overriding clutch is connected with one end of the cross shaft; the overriding clutch is provided with a compression spring and is connected respectively with a brake side cover plate and a planet wheel via a left and a right driving barrel. The utility model realizes the bicycle to operate in the first, second gear and neutral position while the overriding clutch revolutes via the left and right driving barrel connecting with the brake side cover plate and the planet gear pan under the action of the compression spring, main pin shaft and cross shaft. The utility model has the advantages of reasonable structure, convenient operation and agile gear shifting, stable output voltage and big power, which satisfies the different slope climbing capability requirements.
Description
Technical field
The utility model belongs to the elec. vehicle class, specifically is a kind of Electrical Bicycle mechanical speed change mechanism.
Background technology
Electrical Bicycle normally relies on change output voltage size to change rotating speed, because horsepower output is little, torque is low, causes hill climbing ability poor, can not satisfy the demand of the actual use of user when up-hill journey.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of large torque, high-power that has is provided, and rational in infrastructure, the gearshift that can satisfy the various hill climbing ability requirements of user make things convenient for, rotate Electrical Bicycle mechanical speed change mechanism flexibly.
The technical solution of the utility model is as follows:
A kind of Electrical Bicycle mechanical speed change mechanism, comprise motor, gear housing, transmission gear, stub axle, cotter axle, drive splines cover, band-type brake, gear ring, satellite gear, sun wheel, wheel hub, flywheel, adjusting handgrip, governor, it is characterized in that: regulate the interlock of handgrip and cotter axle, cotter axle one end is connected on the stub axle, have overriding clutch on the stub axle, overriding clutch has pressure spring, and respectively by about take off post and connect band-type brake side cover plate and satellite gear.
The utility model overriding clutch under the effect of pressure spring, stub axle, cotter axle respectively by about take off post and connect band-type brake side cover plate and planet crop rotation revolution motion, realize a retaining, two retaining speed changes and neutral operation.The utility model is rational in infrastructure, easy to operate, gearshift is flexible, and output voltage stabilization, and power is big, can satisfy the various hill climbing ability requirements of user.
Description of drawings
Fig. 1 is the utility model two retaining (slow block) structural representations.
Fig. 2 is the utility model one retaining (fast block) structural representation.
Fig. 3 is the utility model neutral structural representation.
The specific embodiment
As Fig. 1,2, shown in 3, a kind of Electrical Bicycle mechanical speed change mechanism, comprise motor 1, gear housing 2, transmission gear 3,24, stub axle 11, cotter axle 15, drive splines cover 4, band-type brake 5, band-type brake side cover plate 23, gear ring 9, satellite gear 10, sun wheel 12, wheel hub 21, hub spindle 13, flywheel 14, flywheel side end cap 20, regulate handgrip 19, chain stay 16, governor 17, speed governing line 18, it is characterized in that: regulate handgrip 19 and cotter axle 15 interlocks, cotter axle 15 1 ends are connected on the stub axle 11, have overriding clutch 7 on the stub axle 11, overriding clutch 7 has pressure spring 6, and respectively by Left Drive post 22, the right side takes off post and 8 connects band-type brake side cover plates 23 and satellite gears 10.
As shown in Figure 1, the utility model promotes cotter axle 15 when motor 1 outage by regulating handgrip 19, moves overriding clutch 7 and 22 realizes two retaining slow block speed changes with band-type brake side cover plate 23 combination backs by taking off post thereby promote stub axle 11; With cutting off the power supply by motor 1, as shown in Figure 2, by regulating handgrip 19 under the effect of pressure spring 6, make overriding clutch 7 along drive splines cover 4 from take off post 22 eject after, sliding into takes off post 8 drives three planetary wheels 10 and makes revolution motion and drive gear ring 9 and wheel hub 21 and rotate and realize a retaining fast block speed change.
Change-speed box of the present utility model can be designed to two retainings, also can increase by a neutral, be overriding clutch 7 with take off post 8, taking off post 22 is not connected, be with a neutral gear position, as shown in Figure 3, i.e. motor outage, by regulating handgrip 19, under the effect of pressure spring 6, make overriding clutch 7 mediate neutral gear position (with take off post 8, taking off post 22 is not connected), realize neutral.
