Problems solved by technology

Even if the power of the motor is increased, the current motor technology will still cause the electric vehicle to start slowly. In order to achieve a fast start of the electric vehicle, it is necessary to add a gearbox to the electric vehicle. Adding a gearbox will greatly increase the manufacturing cost to a certain extent. So how to reasonably solve this problem without increasing the gearbox is very meaningful

Abstract

The invention belongs to the technical field of speed changing, and particularly relates to a three-gear speed changing wheel based on electromagnetic gear shift. The three-gear speed changing wheel comprises a three-gear wheel hub, three-gear wheel transmission gears, three-gear wheel driving gears, three-gear wheel driving gear clutch mechanisms, three-gear wheel driving shaft circular sections and three-gear wheel driving shaft non-circular sections, the three driving gears are mounted on a driving shaft and meshed with the three transmission gears which are meshed with inner teeth of the inner surface of the hub, the driving gears and the transmission gears are meshed respectively to form three transmission ratios, and one driving gear clutch mechanism is mounted on each of the three driving gears; the driving gear clutch mechanisms can engage and disengage a transmission relation between the driving shaft and the driving gears to enable the driving shaft to selectively drive one driving gear, a driving ratio is determined at the same time, and in this way, the wheel is driven through meshing between the transmission gears and the inner teeth of the hub. Speed changing of the wheel itself is realized through three-gear driving, so that a transmission is omitted and the three-gear speed changing wheel has good actual effect.

Description

Technical field [0001] The invention belongs to the technical field of speed change, and in particular relates to a three-speed speed change wheel based on electromagnetic shifting. Background technique [0002] At present, the driving technology of small electric vehicles is to directly use the electric motor coupled with the reducer to drive the wheels, and adjust the motor speed and torque by adjusting the current of the driving motor to change the vehicle speed. Because the initial torque required for electric vehicles to start is very large, this requires the electric motor to have high power. Even if the power of the motor is increased, the current motor technology will still cause the electric vehicle to start slowly. In order to achieve a fast start of the electric vehicle, it is necessary to add a gearbox to the electric vehicle. Adding a gearbox will greatly increase the manufacturing cost to a certain extent. So how to reasonably solve this problem without increa...
