When the assembly is used, when the wheel 3 is contacted with the ground and the wheel is driven to run at low speed, the wheel 3 rotates to drive the supporting shaft 32 to rotate, the supporting shaft 32 drives the eccentric wheel 31 to rotate, because the limiting shaft 44 is connected in the limiting chute 311 in a sliding manner, the limiting shaft 44 is fixedly connected with the piston head 45 through the connecting rod 43, and the piston head 45 is connected in the inflator pump 4 in a sliding manner, the limiting shaft 44, the connecting rod 43 and the piston head 45 can be driven to do reciprocating motion under the limiting condition of the inflator pump 4 by the limiting chute 311 in the rotating process of the eccentric wheel 31, so that the piston head 45 can suck the outside air through the air suction pipe 42 and fill the air into the pressurizing cylinder 5 through the air charging pipe 41, and the eccentric wheel 31 is fixedly connected to two ends of the supporting shaft 32 in a symmetrical and staggered manner, so that the inflator pump 4 can always fill the air into the wheel 3 in the rotating process, the air filled in the inflator 4 can increase the air pressure in the inflator 4, so that redundant air is continuously discharged outwards through the flow limiting pipe 51 under the action of the internal and external atmospheric pressures, because the speed of the two inflators 4 inflating the pressurizing cylinder 5 is slower in the low-speed running process of the wheel 3, the speed of the air filled in the pressurizing cylinder 5 is slower in the outwards discharging through the flow limiting pipe 51, the increase value of the air pressure in the pressurizing cylinder 5 is smaller, the thrust of the friction column 52 which is pushed towards the friction wheel 23 by the sealing plug 53 with the smaller air pressure value increased in the pressurizing cylinder 5 is smaller, so that the relative sliding friction force between the friction column 52 and the surface of the friction wheel 23 is smaller, and thus the steering assembly can not provide larger steering resistance to steering when the wheel 3 runs at low speed, so that a driver can flexibly turn at low speed, the operation is convenient, and when the wheel 3 runs at high speed, the inflator 4 can rapidly inflate the inside of the pressurization cylinder 5 under the action of the eccentric wheel 31, the air is discharged outwards through the flow limiting pipe 51 at a high speed, the increased value of the air pressure in the pressurization cylinder 5 is also large, the thrust of the increased value of the atmospheric pressure in the pressurization cylinder 5 pushing the friction column 52 towards the friction wheel 23 through the sealing plug 53 is large, so that the relative sliding friction force between the friction column 52 and the friction wheel 23 is large, when the wheel 3 is blocked by obstacles such as stones and the like during the driving process to generate a reverse acting force, the reverse acting force needs to counteract the friction resistance between the friction column 52 and the friction wheel 23 when the wheel 3 is pushed reversely to rotate, so that the direction angle of the rotation of the wheel 3 under the reverse action of the obstacles such as stones and the like during the driving process is small, a driver can conveniently reset and adjust the direction of the wheel 3 through the friction column 52 and the friction wheel 23 through the handle 21, and the phenomenon that the steering resistance of the wheel 3 is excessively heavy and the vehicle is prevented from being turned over during the high-speed driving process, and the stability of the vehicle is improved due to the phenomenon that the vehicle is caused by the heavy-feeling during the vehicle-turning over.
