The invention relates to the technical field of wheel vibration reduction, and provides a telescopic hob wheel which comprises an outer hub, an inner hub is embedded in the outer hub, a first annular groove is formed in the inner hub in the circumferential direction, a plurality of hob grooves are evenly distributed in the circumferential direction of the first annular groove, a gear ring is installed on the periphery of the annular groove, gear teeth are arranged on the two sides of the gear ring, and the gear teeth are meshed with the hob grooves. A plurality of rotating shafts are evenly distributed in the annular groove, pinions are installed on the rotating shafts, hobs are installed in the hob grooves in a sliding mode, gear teeth are formed in the hobs, the hobs and the inner side of the gear ring are meshed with the pinions through the gear teeth at the same time, the outer side of the gear ring is meshed with a driving gear, and the driving gear is driven by a motor. The telescopic wheel train type traveling mechanism crosses over obstacles, meanwhile, impact force caused by uneven road surfaces can be effectively damped and absorbed through stretching and retracting of the hobs, and the stability and safety of vehicle traveling are improved.
