Abstract
The utility model discloses a variable speed motor-assisted bicycle, which comprises all components with each function of the existing manual braking variable speed bicycle. The utility model is characterized in that the variable speed motor-assisted bicycle is provided with an engine; the output shaft end of the engine is coaxially provided with a large chain wheel and a small chain wheel; the power transmission mechanism is composed of the coaxial small chain wheel, a step variable speed device arranged on a rear shaft and a chain; a manual transmission mechanism is composed of the coaxial large chain wheel, a pedal chain wheel arranged on the same side with the large chain wheel, and a chain. The variable speed motor-assisted bicycle reasonably make a mobile device dissolve the transmission mechanism of a normal variable speed bicycle. Then the normal variable speed bicycle can become a double purpose motor-assisted bicycle which not only can depend on an engine for driving, but also can be driven by pedal driving. The utility model has the advantages of convenient speed regulation, simple structure and safe operation. The utility model is an economic variable speed motor-assisted bicycle.
Description
The utility model relates to morpet, but especially a kind of morpet of step change.
At present, the kind of boosted vehicle is more on the market, the boosted vehicle of reliable friction tire wheel drive; The boosted vehicle that installs power machine on conventional bicycle additional is arranged; Also have its structure and the essentially identical boosted vehicle of motor bike.They all adopt simple put-put as power, and it is light more, quick that people are ridden.But all there is corresponding defective, as: rely on the boosted vehicle of the tire wheel drive of rubbing, tire chafing is serious, and is fragile, and can not speed change, and the transmission efficiency of machine is low.Though the sort of boosted vehicle that installs power machine on bicycle additional can improve the transmission efficiency of machine, structure is complicated, also can not realize that speed change travels.
The purpose of this utility model is the deficiency that exists at above-mentioned boosted vehicle, a kind of simple in structure, machine transmission efficiency height is provided, and the boosted vehicle that can speed change travels.
Variable speed motor-assisted bicycle of the present utility model comprises front axle, front-wheel, rear axle, trailing wheel, handle-bar that existing rim brake variable speed bicycle had, drives seat and brake gear etc., it is characterized in that: above-mentioned parts are installed in one and can be provided with on the vehicle frame of driving engine, the engine output shaft end is coaxially installed with big minor sprocket, step change device and chain on coaxial minor sprocket and the rear axle constitute motor-driven transmission device, and foot-operated sprocket wheel that coaxial big sprocket is parallel with being arranged on its homonymy and chain constitute people's force transmission mechanism.
The all functions parts that Variable speed motor-assisted bicycle of the present utility model utilizes existing variable speed bicycle to be possessed dexterously, reasonably in the transmission device of variable speed bicycle, dissolve in tracker action, both made it to become and to rely on engine drive, again can be under the non-operating condition of driving engine, by the foot-operated dual purpose boosted vehicle that car body is travelled of manpower.Because this car has adopted the hand adjustment steel rope to spur speed change, to change the speed setting that chain and different number of teeth chain sprocket drive realize boosted vehicle, its operation is very convenient.More because this car is improved based on existing variable speed bicycle, so it need increase or add mutual part again seldom, commonality is good, simple in structure, fault rate reduces greatly, cost is low, uses safety of operation reliable, is a kind ofly to collect existing boosted vehicle and the variable speed bicycle advantage is the economical Variable speed motor-assisted bicycle of a car.
The concrete structure of Variable speed motor-assisted bicycle of the present utility model is provided in detail by the following drawings and embodiment.
Fig. 1 is the structural representation of Variable speed motor-assisted bicycle.
Embodiment: can be clear that from Fig. 1 Variable speed motor-assisted bicycle comprises vehicle frame 1, handle-bar 2, front fork 3, front axle 4, front-wheel 5, rear axle 6, trailing wheel 7, the step change device of being made up of speed-changing chain 8 and change-speed box 9 is set on the rear axle 6, its structure is identical with the transmission system of existing variable speed bicycle, the middle part of vehicle frame 1 is driven seat 16 belows driving engine 10 is set, the output axle head of driving engine 10 is equipped with coaxial big minor sprocket 11,12, by chain 13 minor sprocket on the output shaft 12 and the transmission system on the rear axle 6 are constituted the motor-driven transmission device of this car,, will ride people's force transmission mechanism of sprocket wheel 14 and coaxial big sprocket 11 these cars of formation by chain 15 at the place ahead and hinge wheel 11 homonymies of the driving engine 10 output shafts foot-operated sprocket wheel 14 that be arranged in parallel.The brake gear of this car can adopt existing rim brake formula brake, the rim brake handle of brake, and governor handle all is arranged on the handle-bar 2.Its operating mode is identical with conventional variable speed bicycle.
In order to make operator's saddle horse comfortable, the seat 16 of driving of this car is the chair with back structure.
This car both can utilize driving engine 10 driving car bodies to advance, and in the time of can working as driving engine 10 et out of orders again, utilized foot-operated sprocket wheel 13, realized conventional bicycle function.
Claims (2)
1, a kind of Variable speed motor-assisted bicycle, comprise front axle, front-wheel, rear axle, trailing wheel, handle-bar that existing rim brake variable speed bicycle had, drive seat and brake gear etc., it is characterized in that: above-mentioned parts are installed in one and can be provided with on the vehicle frame of driving engine, the engine output shaft end is coaxially installed with big minor sprocket, step change device on minor sprocket and the rear axle constitutes motor-driven transmission device by chain, and the hinge wheel foot-operated sprocket wheel parallel with being arranged on its homonymy constitutes people's force transmission mechanism by chain.
2, according to the described Variable speed motor-assisted bicycle of claim, it is characterized in that: drive seat and be the chair with back structure.
