Electric vehicle speed change magnetic force motor rotating-speed reduction apparatus

Abstract

The invention discloses an electric vehicle speed change magnetic force motor rotating-speed reduction apparatus, and belongs to the electric vehicle speed change field. The technical problem solved by the electric vehicle speed change magnetic force motor rotating-speed reduction apparatus is that an electromagnetic brake apparatus which can improve the cruising power of a storage battery is provided, and matches the motor of an electric vehicle to use. The technical scheme of the electric vehicle speed change magnetic force motor rotating-speed reduction apparatus is that for the electric vehicle speed change magnetic force motor rotating-speed reduction apparatus, a magnetic line bag and a brake disc are arranged on a flywheel housing; two sides of the flywheel housing are fixedly connected with a power motor and a transmission correspondingly; and the magnetic line bag is used to push the brake disc to generate frictional resistance on the flywheel, so as to reduce the rotating speed of the motor and perform gear shifting on the transmission to improve the driving speed of the electric vehicle. The electric vehicle speed change magnetic force motor rotating-speed reduction apparatus can be widely applied to the electric vehicle field.

Description

technical field [0001] The invention relates to a device for reducing the rotational speed of a motor by magnetic force for variable speed of electric vehicles, belonging to the technical field of variable speed for electric vehicles. Background technique [0002] The existing electric vehicle transmission principle is to directly transmit the driving torque of the motor to the drive shaft of the car, and rely on the vehicle power supply to provide the power source to drive the motor to start the load. There is no gearbox, and the driving motor is realized through the environment controlled by the circuit. The control of direction and speed, so the speed of electric vehicles is fixed and proportional to the speed of the vehicle. The faster the motor turns, the higher the speed of the vehicle. To increase the speed of the vehicle, the speed of the motor must be increased, and the load current will increase accordingly. So now Some electric vehicles have a short service life, ...

[0002] The existing electric vehicle transmission principle is to directly transmit the driving torque of the motor to the drive shaft of the car, and rely on the vehicle power supply to provide the power source to drive the motor to start the load. There is no gearbox, and the driving motor is realized through the environment controlled by the circuit. The control of direction and speed, so the speed of electric vehicles is fixed and proportional to the speed of the vehicle. The faster the motor turns, the higher the speed of the vehicle. To increase the speed of the vehicle, the speed of the motor must be increased, and the load current will increase accordingly. So now Some electric vehicles have a short service life, many charging times, and insufficient battery life. At the same time, the motor speed is fast and the noise is loud.
