The invention relates to a combined type wheel burr brush, consisting of a lower bottom plate, lantern rings, nylon brush units, an upper bottom plate, steel-wire brush units and the like, wherein the steel-wire brush units in II and IV areas are floating, and under a natural state, the height of the steel-wire brush units is 10 mm higher than that of the nylon brush units; when in work, the steel-wire brush units firstly contact a spoke of a back cavity of a wheel, burrs of the back cavity of the wheel can be removed powerfully when the steel-wire brush units rotate, the steel-wire brush units are continuously compressed, and when the nylon brush units also contact the spoke of the back cavity, burrs at corners can be smoothened; and when a small-size wheel is encountered, by removing the lower bottom plate, the fast locks and the lantern rings, a small-size burr brush can be formed. When the burr brush combining the steel-wire brush units with the nylon brush units of the invention is in use, not only can the efficiency of removing the burrs of the back cavity of the wheel be improved, but also the removing effect is very obvious, and meanwhile, the service life of the brush can be greatly prolonged.
