Problems solved by technology

The motors used in the existing three-wheeled electric vehicles are rear-drive brushless motors, which are driven by mechanisms such as gear box speed change, differential speed or wheel motors. Although this motor can meet the requirements of providing power for three-wheeled electric vehicles , but this kind of motor has a small ground clearance, high working noise, low working efficiency, and large volume, which brings inconvenience to the structural design, manufacturing and actual use of the three-wheeled electric vehicle

Abstract

The invention discloses a brushless motor for a three-wheeled electric vehicle. The motor comprises a motor body, a front end cover and a rear end cover. A motor shell is arranged on the outer surfaceof the motor main body; a motor hollow shaft is arranged in the motor main body; the upper end and the lower end of the motor hollow shaft are each provided with a short cover and a supporting partition plate. A differential mechanism is arranged on one side of the motor hollow shaft; rotors installed at the upper end and the lower end of a hollow shaft of the motor are arranged on one side of the supporting partition plate, a stator is arranged between the rotors and the motor shell, the rotors are located in the stator, emergency braking gears fixed to the motor shell are arranged above andbelow the differential mechanism, and the emergency braking gears are connected to the motor shell through hydraulic telescopic rods. The invention has the advantages of high torque, low rotating speed, low working noise and high working efficiency; operation stability is good, the failure rate is low, the service life is long, emergency braking can be achieved, and dangers are avoided.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a brushless motor for a three-wheel electric vehicle. Background technique [0002] With the development of science and technology, the global environmental crisis and energy crisis have intensified, electric vehicles have become a common green transportation tool in life due to their non-polluting, zero-emission and low-energy consumption properties, and have been very popular in my country. widespread popularity. The motors used in the existing three-wheeled electric vehicles are rear-drive brushless motors, which are driven by mechanisms such as gear box speed change, differential speed or wheel motors. Although this motor can meet the requirements of providing power for three-wheeled electric vehicles , but the ground clearance of this motor is small, the working noise is large, the working efficiency is low, and the volume is large, which brings inconvenience to th...
