Abstract
The utility model designs a manpower driving device for an electric bicycle with small wheel diameter, the structure of the compound transmission of a gear and a chain is used, thus the electric bicycle with small wheel diameter (less than 510 mm) can be completely met the requirements of the manpower riding speed and the ground distance of the electric bicycle prescribed by national standard. The manpower driving device, which comprises a chain 104 and a flywheel 502, is characterized in that a driving gear 204 is arranged on a medial axis 202 to for a medial shaft assembly 101, a transition gear 303 is arranged on a transition shaft 301 to form a transition shaft assembly 102, a driven gear 408 and a flywheel 404 are arranged in parallel on a rotary shaft 401 to form a connection shaft assembly 103, therein, the driving gear 204 is mutually meshed with the transition gear 303, and the transition gear 303 is mutually meshed with the driven gear 408.
Description
Technical field
The utility model belongs to the driver for vehicle class, specifically a kind of steamboat footpath Electrical Bicycle Manpower driver.
Background technology
Existing Electrical Bicycle manpower driving system adopts 36/16,32/16 chain-driving usually, and this transmitting ratio can not satisfy the requirement of steamboat footpath (less than 510mm) Electrical Bicycle to the manpower riding speed; Because the restriction of installation dimension on the electric wheel hub can not be used the flywheel of 12 teeth again, and increases the number of teeth of sprocket wheel, certainly will add the diameter of hinge wheel, influences the attractive in appearance of car load profile.
Summary of the invention
The purpose of this utility model then is the problem that exists at above-mentioned prior art, designed a kind of structure that adopts gear and chain mixed drive, made steamboat footpath (less than 510mm) Electrical Bicycle can satisfy the Manpower driver that requires about Electrical Bicycle manpower riding speed and ground distance of national standard defined fully.
The purpose of this utility model can reach by following measure:
A kind of steamboat footpath Electrical Bicycle Manpower driver, comprise chain 104, flywheel 502, it is characterized in that driving gear 204 is installed in formation Middle shaft assembly 101 on the axis 202, transition gear 303 is installed in and constitutes transition axis assembly 102 on the transition axis 301, driven gear 408 is installed in parallel with flywheel 404 and constitutes adapter shaft assembly 103 in rotating shaft 401, wherein, driving gear 204 is meshed with driven gear 408 with transition gear 303, transition gear 303.
Advantage of the present utility model:
The utility model has designed a kind of new Manpower driver, it adopts gear and chain mixed drive structure, by set of gears, flywheel mechanism, substituted the sprocket wheel in the former chain-driving, thereby increased transmitting ratio, make the performance of steamboat footpath (less than 510mm) Electrical Bicycle manpower riding speed and ground distance, can satisfy the requirement of national standard defined fully.The utility model compact conformation, novelty go slick, light; Use need not be considered the problem of chain tension in the car load of center anti-vibration structure; This structure can make the car load design of steamboat footpath (less than 510mm) Electrical Bicycle easy, and moulding is more beautiful.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Connecting panel 201,203 is welded on the center tap 202 corresponding positions, center tap 202 is welded on the vehicle frame again, driving gear 204, bearing pin 205, spring cotter 206 are packed in order into corresponding axle is gone up and the hole in; Bearing 304 is pressed in the transition gear 303, loads onto hole collar 306, the transition axis 301 of packing in order, connecting panel 201,203, axle collar 302,305; With bearing 406,407 order be pressed into driven gear 408 in, load onto the hole with collar 405, screw on flywheel 404, the rotating shaft 401 of packing in order, connecting panel 201, Vee formation 402, connecting panel 203, axle are with collar 403,409; Flywheel 502 is spun on formation rear axle assemblies 105 on the motor wheel hub 501, chain 104 is installed on flywheel 404, flywheel 502.Driving gear 204 is 2.8～3.4 with the transmitting ratio of driven gear 408, and flywheel 404 is 0.5～1.5 with flywheel 502 transmitting ratios.
Step on and ride, drive driving gears 204, transition gear 303, driven gear 408, flywheel 404 rotations by crank, axis 202, drive flywheels 502 by chain 104 and rotate, thereby driving electric wheel hub 501 rotates, the drive wheel advances.
