Abstract
The utility model discloses an electric and mechanical double speed changing device of an electric bicycle, comprising a set of frame, two wheels and a mechanical variable speed control device; the utility model is characterized in that two parallel driving wheels are arranged on a roulette,, a fixed motor is on the bicycle frame, a transmission wheel is arranged on the output shaft of a motor , the two transmission wheels are connected through a driving belt, the roulette is connected with a shifting flywheel arranged on the rear wheel. The utility model has the advantages of improving the working state of speed variable motor and prolonging the service life of bicycle and enhancing the application efficiency.
Description
Technical field
The utility model relates to a kind of transmission system of Electrical Bicycle.
Technical background
Speed when existing Electrical Bicycle is mostly regulated bicycle and advanced by the size of the electric current on the control hub-type motor promptly can only realize speed change with motor.When Electrical Bicycle start, climbing or when advancing against the wind, promote the power of bicycle often by the electric current on the expanded motor, but, the motor of this moment still is in low speed state, and electric current is very big, amount increases thereby cause that the motor feels hot, makes the magnet steel in the motor fall magnetic easily, has influenced the result of use and the life-span of Electrical Bicycle.And the prior mechanical speed change in fact also is applicable to Electrical Bicycle, but its use and motor and onrelevant, and it is to use when manpower is ridden.
The utility model content
The purpose of this utility model is to provide a kind of mechanical, electrical pair of transmission system of Electrical Bicycle, to improve the mode of operation of electrical motor gearshift.
Mechanical, electrical pair of transmission system of Electrical Bicycle described in the utility model, comprise vehicle frame, wheel and mechanical speed change control setup, it is characterized in that: power wheel arranged side by side is housed on the wheel disc, fixed electrical machinery on the vehicle frame, power wheel is installed on the motor output shaft, two power wheels are connected by driving band, and wheel disc is connected with gear shift flywheel on being installed in trailing wheel by chain.
Mechanical, electrical pair of transmission system of Electrical Bicycle described in the utility model, the size of current by on the control motor can realize electrical motor gearshift; And regulate the mechanical speed change control setup, and change the number of teeth ratio between gear shift flywheel and wheel disc, can realize mechanical speed change; Electrical Bicycle starts when for example occurring, climbing or when big resistance situation such as advancing against the wind, can two kinds of speed changes be used in combination, reduce power demand by mechanical speed change to motor, reduce the workload of motor, thereby improve the working condition of motor, prolonged the result of use and the life-span of Electrical Bicycle.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a local structure scheme drawing of the present utility model.
The specific embodiment
Mechanical, electrical pair of transmission system of Electrical Bicycle described in the utility model, as shown in Figure 1 and Figure 2, comprise vehicle frame 8, wheel 9 and mechanical speed change control setup, power wheel 2A is installed in wheel disc 1 outside side by side, can certainly be contained in wheel disc 1 inboard, fixed electrical machinery 3 on the vehicle frame 8, power wheel 2B is installed on motor 3 output shafts, two power wheels are connected by driving band 4, described power wheel 2A and 2B are sprocket wheel, driving band 4 is a chain, and wheel disc 1 is connected with gear shift flywheel 6 on being installed in trailing wheel by chain 5, and gear shift flywheel 6 is made of the gear of a plurality of different numbers of teeth.Drive motor when preventing foot-operated reversing and also reverse, on wheel disc 1 and motor 3 output shafts ratchet 7 mechanisms are housed respectively, the interior ratchet device of its structure and mechanical speed change flywheel is identical, and this is a known technology.
Mechanical, electrical pair of transmission system of Electrical Bicycle described in the utility model, described power wheel also can be belt pulleys, and belt conveyor is a belt.
