The two-wheeled vehicle driven by the engine is not provided with a reversing gear on the transmission, and can only assist reversing or turning by manpower pushing, when the two-wheeled vehicle runs in a narrow road section or on a slope, the two-wheeled vehicle cannot be reversed or turned due to overweight of the vehicle, or cannot automatically go to a maintenance point for maintenance when the vehicle breaks down and cannot run.
The front brake and the rear brake are respectively used for braking in vehicle braking, the braking mode is single, and the braking efficiency is low. When the front wheel brake is used, the rear wheel can only depend on the engine to assist in speed reduction, when the vehicle speed is high, the rotating speed of the engine is correspondingly increased, at the moment, the traction resistance generated by the engine is almost zero, and the probability of sideslip generated during vehicle braking is increased. When the vehicle uses the brake on a slope, the brake generates high temperature due to long-time use, so that the braking capability of the brake is reduced, the braking distance of the vehicle is increased, and the consumption of the brake is increased.

The number of the first coils (4.1) and the number of the second coils (54.2) are respectively more than 6; the first coil (4.1) and the second coil (4.2) are respectively arranged on the first electromagnetic core (3.1) and the second electromagnetic core (3.2).
The magnetic conductive ring is arranged between the first electromagnetic iron core (3.1) and the second electromagnetic iron core (3.2) and corresponds to the permanent magnet (2) arranged on the wheel hub (1).
After the first coil (4.1) and the second coil (4.2) are alternately electrified, the first electromagnetic iron core (3.1) and the second electromagnetic iron core (3.2) can alternately generate different magnetic poles.
The permanent magnet (2) is arranged on the inner side of the hub (1) and is fixed on the hub (1).

Adopt above-mentioned technical scheme's beneficial effect:
when the vehicle does not need high power, the coil on one side of the wheel is only needed to be supplied with power, the redundant part is changed into electric energy to be stored in the battery pack, and when the vehicle needs larger power, the coil on the two sides of the wheel can be simultaneously supplied with power, so that the transmission efficiency is improved, the vehicle is in the best working state more times, the fuel consumption is reduced, and the environmental pollution is reduced.
When the vehicle is not braked by using the wheel brake, the motor works before the brake, the vehicle speed is slowly reduced by the dragging action of the motor, the loss of the brake is reduced, and the probability of sideslip generated when the vehicle is braked is reduced. After the wheel brake is used for braking, the motor and the wheel brake work simultaneously, so that the high temperature generated during braking is reduced, the braking force is increased, the braking distance of the vehicle is reduced, and the vehicle can be stopped in a short time.
