Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
As shown in fig. 1 to 4, the scooter motor wheel comprises a hub motor 1 and a corner sensor 4, wherein the centers of two side surfaces of the hub motor 1 are outwards extended out of a rotating shaft 1a, a hole is formed in the rotating shaft 1a for a power line of the hub motor 1 to pass through, an arc sleeve 2 is arranged at the outer end of the rotating shaft 1a, the arc sleeve 2 limits the vertical displacement of the rotating shaft 1a, a corner device 3 is arranged between the rotating shaft 1a and a scooter frame, the corner device 3 drives the rotating shaft 1a to horizontally rotate in the arc sleeve 2 or keep fixed, the arc sleeve 2 is connected with the scooter frame, the arc sleeve 2 is in a shape of a V, the arc sleeve 2 is symmetrically arranged at two sides of the hub motor 1, a horizontal chute is arranged at the inner periphery, and the outer tail end of the rotating shaft 1a is arranged in the chute; the steering angle sensor 4 is linked with the front steering shaft of the scooter and is a sensor for measuring the turning angle of an object, the steering angle of the front steering shaft of the scooter is detected in the technical scheme, signals are fed back to the control system, the control system controls the steering angle device 3 to move, and finally the scooter rear wheel with the hub motor 1 is used for assisting the front wheel to steer, so that the turning radius of the scooter is reduced, and the control performance is improved.
The hub motor 1 is characterized in that a power device and a transmission device are integrated into a hub, so that the mechanical part of an electric vehicle is greatly simplified, the transmission of the electric vehicle by a chain is not required as in a vehicle with a middle motor, and the transmission efficiency is increased; the corner device 3 comprises a circular arc rack 3a and a gear 3b which are engaged and matched, the circular arc rack 3a is fixed with the rotating shaft 1a, the gear 3b is driven by a corner motor 3c fixed with the scooter frame, power is transmitted between the corner motor 3c and the gear 3b through a self-locking reduction gearbox, the corner motor 3c is one of a stepping motor and a servo motor, the two motors can control the rotating angle of an output shaft, and the circular arc rack 3a is positioned at the inner side of the circular arc sleeve 2 and is not contacted with the hub motor 1; when the front steering shaft of the scooter turns left, the gear 3b rotates anticlockwise, the circular arc racks 3a drive the rotating shaft 1a and the hub motor 1 to turn right, and vice versa, when the front steering shaft of the scooter does not turn, the gear 3b is positioned in the middle range of the circular arc racks 3a and locked, so that the scooter moves straight, and at the moment, the circular arc racks 3a on the two sides of the gear 3b have activity allowance.
