The invention provides a travelling wheel of a railway track measuring vehicle and the railway track measuring vehicle. The travelling wheel comprises a wheel body, a wheel carrier and an encoder, thewheel body is arranged at the inner side of the wheel carrier, the wheel body comprises a wheel shaft, a wheel core and a wheel sleeve which are coaxially connected in sequence from inside to outside, and the wheel shaft and the wheel core are both made of metal materials. The middle of the wheel shaft is connected with the inner ring of the wheel core through a spline, the two ends of the wheelshaft are connected with the wheel carrier through bearings respectively, the wheel sleeve is made of ceramic, connected with the outer ring of the wheel core in a sleeving mode and connected with thewheel core through glue injection, the two sides of the wheel sleeve are each provided with a protection piece in a bonded mode, and the wheel core is sleeved with the two protection pieces. The encoder is mounted on one side of the wheel carrier through a mounting sleeve and is synchronously and rotationally connected with the end part of the wheel shaft through a coupler. The outermost part ofthe wheel body is made of a ceramic material, so that the requirements of insulation, wear resistance and no deformation can be effectively met when the track measuring vehicle works, and the mileagemeasuring precision of the vehicle is ensured.
