Split type electric scooter drive assembly

Abstract

The application relates to a split type electric scooter driving assembly, belonging to the technical field of electric scooters, which comprises a mounting frame, a driving motor, a wheel hub and a fixing assembly, the driving motor is installed on the mounting frame, the driving motor comprises a rotary support cylinder which is a power output component of the driving motor; at least two mounting blocks are connected on the outer wall of the rotary support cylinder along the circumferential direction of the self axis; at least two connecting blocks are connected on the inner ring of the wheel hub along the circumferential direction of the self axis; each connecting block is connected with the corresponding mounting block through the fixing assembly; the fixing assembly is used for positioning the connecting block on the wheel hub on the mounting block on the rotary support cylinder; the application realizes the separable installation of the driving motor and the wheel hub; when the driving motor is faulty and the wheel hub is intact, the driving motor is separately disassembled for replacement; when the wheel hub is damaged and the driving motor is normal, the wheel hub is separately replaced; the replacement of the whole driving assembly is avoided, and the maintenance cost and resource consumption are reduced.
