The invention relates to the automobile manufacturing field, in particular to a telescoping automobile wheel. The telescoping automobile wheel comprises a pair of wheels symmetrically arranged at two sides of an automobile underframe, and a transmission shaft used for driving the pair of wheels to rotate. The transmission shaft is connected to a power output end of an automobile transmission assembly by a differential mechanism. Stationary shafts are arranged parallel to each other at a side of the transmission shaft and arranged on the underframe. A transmission mechanism is connected between the transmission shaft and the stationary shafts and an output end of the transmission mechanism is fixedly connected to webs of the wheels. The stationary shafts are hollow tubular, wherein telescoping mechanisms are disposed in the tubular cavities of the stationary shafts and stretche in a reciprocating manner in the axial direction of wheel hubs. A connecting device adaptively connected to the telescoping automobile wheel comprises rear wheels of a front vehicle and a telescoping mechanism disposed therein. Projecting shaft caps of the telescoping mechanism can be arranged in front hollow wheels of a rear vehicle when in an extendable condition, or separated from the front hollow wheels when in a retracted condition. With the adoption of the telescoping mechanism, stretchable property of the wheels can be realized and assembly requirements of the front and rear vehicles in connection can be satisfied.
