Low-noise mine car rotating wheel

The invention discloses a low-noise mine car rotating wheel which comprises a tread and a rim. An axle is installed in the middle of the tread, a connecting supporting plate is movably connected to the outer side of the axle, the rim is arranged on the outer side of the tread, noise-absorbing cotton is arranged on the rear surface of the tread, and a fixing ring is arranged on the outer side of the noise-absorbing cotton. A supporting platform of the low-noise mine car rotating wheel can connect a mine car with the rotating wheel through first springs, noise-reducing hydraulic cylinders and connecting rods, then the contact area between the mine car and the rotating wheel can be increased, and thus it can be avoided that minerals in the mine car are not placed uniformly and consequently the running of the rotating wheel is affected; the arrangement of the noise-reducing hydraulic cylinders can achieve the effect of noise reduction, the stretching and retracting between the noise-reducing hydraulic cylinders a
