Embodiment Construction

[0016] Electromechanical stepless speed regulation motor for electric vehicle of the present invention, such as figure 1 As shown, the DC series excited two-speed motor is on one side of the gearbox seat 9, and the speed change gearbox is arranged on the other side of the gearbox seat 9 and the electronic control system 1 is arranged at the bottom thereof, and the sealing gasket 10 and the gearbox cover 11 will The transmission system, the speed regulating system, the overrunning system and the one-way clutch system are sealed in the gearbox and limit the axial movement of the sprocket 8. Pedal power is transmitted to sprocket wheel 8 through central axis 15, key 16, by overrunning clutch system 6, planetary speed change system 7, power planet carrier 61, thereby drives bicycle flywheel, realizes the normal foot riding of bicycle. Motor power passes to sprocket wheel 8 through motor bearing 19, motor driving wheel 18, deceleration driven wheel 12, planetary transmission system...

Abstract

The invention consists of: double speed and tunable DC motor and constant pressure long life carbon brush; planet wheel shift system; power one way automatic on-off system; power taking off excess on-off system; low and high speed excited machine and automatic switching control system. At riding, the feet power can drive the speed control ring gear to make forward and backward rotation and to make the planet speed control system at differential speed control, and that implements stepless acceleration and slowdown.

Description

technical field [0001] The patented product of the present invention is mainly used in supporting electric bicycles and electric tricycles. It is installed at the central axis of electric vehicles and provides efficient and personalized speed-regulating power, which is the key component. Background technique [0002] Electric bicycles are simple and flexible means of transportation that are installed with batteries, motors and control systems on ordinary bicycles. With the expansion of cities, the prohibition of motorcycles in urban areas and the improvement of people's living conditions, electric bicycles are green, convenient and reliable. It is becoming more and more popular. This also provides a broad space for the development of this industry. [0003] The motor and its speed control system are the core components of electric bicycles. Most of the motors used in various electric bicycles currently produced and sold are hub motors, and PWM electronic speed control. This...
