The invention discloses a stably-supported front wheel assembly which comprises a front wheel body. The front wheel body comprises a hub, a plurality of supporting stand columns and an axle connectingpart. The axle connecting part and the hub are circumferentially provided with a plurality of corresponding blind holes and through holes respectively, and each supporting stand column penetrates through the corresponding through hole and then is inserted into the corresponding blind hole to be fixed. A single-arm damping front fork is rotatably connected to the upper end of the supporting frame,the lower end of the supporting frame is fixedly connected to a U-shaped opening of the frame, the supporting frame comprises a supporting arm, a connecting end, a front fork right arm and a front fork left arm, and the connecting end is a hollow cylinder with a small upper end and a large lower end. A front fork left arm and a front fork right arm are symmetrically installed on the left side andthe right side of the lower end respectively to form an inverted U-shaped structure, a supporting arm is installed right in a rear portion, the upper end of the supporting arm is higher than that ofthe front fork left arm or the front fork right arm, a plurality of screw holes are distributed in length direction of the supporting arm and two bolts connected with a chassis are arranged at the lower ends of the front fork left arm and the front fork right arm. According to a three-fork-arm structure, the three-fork-arm structure and the chassis form a tetrahedral stable structure, and the structure is firmer and safer.
