The vibrating shaft 21 rotates at the same speed, and the direction of rotation is opposite to that of the intermediate vibrating shaft 21, then the resultant force of the centrifugal force generated by the three eccentric masses is horizontal, and the effect is horizontal vibration, so the wheel body 1 will produce the least compressive force on the ground . Since the hydraulic swing motor 12 can be automatically controlled according to road conditions, when the drive adjustment gear 27 rotates to any angle between vertical and horizontal, the resultant force of the centrifugal force generated by the three eccentric masses is the tilt direction, and the effect is tilt vibration, thus changing The pressure of wheel 1 on the ground is reduced.
