The present invention discloses a low-floor bogie wheel withdrawal protection device for a wheel withdrawal process when fit between a wheel and an axle is cone fit, and a wheel seat is of a taper structure. The press fitting stroke of the wheel is X. The low-floor bogie wheel withdrawal protection device comprises a nylon sleeve sleeving an end journal of an axle end of the axle, the outer diameter of the nylon sleeve is less than the small diameter of the wheel seat, the nylon sleeve is sleeved with a silicon rubber sleeve, and a distance between an end surface of the silicon rubber sleeve close to the wheel and the wheel is equal or greater than the press fitting stroke X. The low-floor bogie wheel withdrawal protection device also comprises a check ring, and the check ring is used for axially fixing the silicon rubber sleeve to the axle end of the axle. The low-floor bogie wheel withdrawal protection device is simple in structure design and high in manufacturability, the inertia problem of popup of wheels having the similar structure can be solved, and reference can be provided for design of bogies products having the similar structure of rail transit vehicles, thereby facilitating production, repair and maintenance of manufacture companies and users. Qualified rates of wheels after withdrawal can be largely increased, the wheels are prevented from being scrapped, and therefore cost is reduced and benefit is increased. Operation safety is improved, and materials are prevented from being damaged.
