Problems solved by technology
[0002] The power transmission structure of traditional electric vehicles, the motor that outputs power, and the wheel structure that carries the load of the car body are separate devices. The motor and the wheels are connected to transmit power through an external power transmission structure. The power transmission structure is In the exposed form (such as U.S. Patent No. 5934401, U.S. Patent No. 5937964), the power transmission structure is usually used as a power transmission by a non-interfaced belt or chain. Vertical) alignment accuracy is not easy to control, because the alignment accuracy is difficult to control and the transmission structure of the belt and chain will affect the efficiency of power transmission and the difficulty of controlling the transmission noise value. At the same time, the electric vehicle is a mobile tool. The environment of the sports space is very different. If the power transmission structure is polluted by rain, dust, and sand, it will cause troubles in the repair, maintenance, and service life of the power system.

Embodiment Construction
[0022] In Fig. 1A to Fig. 7, an electric wheel structure 10 directly driven by motor power provided by the present invention includes:
[0023] The wheel structure 21 includes a wheel body 211, a wheel shaft core 212, a sleeve 221, a wheel center one-way bearing hole 218, a wheel support bearing 219, a wheel one-way bearing 220, a wheel support frame 214, and a support frame bearing 215. Frame bearing 215 is to be installed in the cavity bearing hole end 216 of wheel support frame 214, and wheel shaft core 212 should wear the inner diameter of support frame bearing 215 and the center matching hole 217 of wheel body 211, and at least one end of wheel shaft core 212 should protrude Because one end face of the support frame bearing 215 is used as the inlaid shaft end 213, the wheel shaft core 212 bears the weight of the vehicle body through the support frame bearing 215 and the support frame 214, and the inlaid shaft end 213 is synchronized with the motor power transmission struct...

The present invention is one integrated structure comprising wheel, motor and power transmitting structure for electric vehicle. The power transmitting structure integrated inside the motor structure is used to drive the shaft of the wheel structure. Between the wheel shaft and the wheel support frame, there is vehicle bearing as bearing interface. The motor structure is fixed onto the wheel support frame and the power output end drives the shaft and the wheel structure to rotate. The electric vehicle with the said structure has raised power transmitting efficiency, no pollution to the power transmitting structure of rain, dust, mud and sand, and thus prolonged life.
