Detailed Description

To further understand the present invention, a preferred embodiment is shown in the drawings and described in detail below:

referring to fig. 3 to 7, the floating disk with an improved structure of the present embodiment includes: a brake disc 20, the center of which has a combination hole 21, and an inner ring surface 22 is formed at the periphery of the combination hole 21, a plurality of ribs 23 surrounding at intervals are provided in the disc body of the brake disc 20, so that an air flow channel 24 is formed between any two ribs 23, and a plurality of expanding sections 25 surrounding at equal intervals are provided on the inner ring surface 22 at the end of part of the ribs 23, and each expanding section 25 is further provided with a radial combination groove 26 in a concave manner; a fixed disk 27, the center of which forms a disk groove 28, the outer edge of the notch of the disk groove 28 forms a disk periphery 29, the disk periphery 29 is penetrated with a plurality of inner screw thread holes 30 which radially correspond to the plurality of combination grooves 26 and are communicated with the disk groove 28; the screw connection columns 31 are axially provided with a driving end 32, an outer thread section 33, a neck reducing section 34 and a neck expanding section 35 in sequence, the neck expanding section 35 is annularly provided with a plurality of cross-sections 36, the outer end edge of the neck expanding section 35 is provided with a chamfer angle edge 37, and the outer diameter of the neck expanding section 35 is slightly larger than the aperture of the combination groove 26; the fixing plate 27 is disposed in the combination hole 21 of the brake disc 20, each of the screw connection columns 31 is screwed into each of the inner screw thread holes 30 from the disc groove 28, and the necking section 34 and the necking section 35 are inserted into the combination groove 26, so that the necking section 35 can elastically contract when inserted into the combination groove 26 by means of the slit 36, and the necking section 35 elastically expands to prop against the combination groove 26 after inserted into the combination groove 26; by means of the above structure, the brake disc 20 and the fixed disc 27 are easily assembled and the manufacturing cost can be reduced, and the neck expanding section 35 of the screw connection column 31 is elastically and tightly supported in the combination groove 26, thereby achieving the effect of reducing abnormal sound.

The composition, action and efficacy of the above examples are explained in detail as follows: referring to fig. 3 to 7, the brake disc 20 and the fixing disc 27 are assembled in such a manner that the diameter of the combination hole 21 of the brake disc 20 is larger than the maximum outer diameter of the fixing disc 27, and therefore, when the inner thread hole 30 of the fixing disc 27 corresponds to the combination groove 26 of the brake disc 20, a distance L (as shown in fig. 7) is maintained between the two holes to provide a space for expansion and contraction when the brake disc 20 is thermally expanded, the screw column 31 is inserted through the inner thread hole 30 on the inner periphery of the disc groove 28 by the enlarged neck section 35, the outer thread section 33 of the screw column 31 is screwed into the inner thread hole 30, although the outer diameter of the enlarged neck section 35 is slightly larger than the diameter of the combination groove 26, the chamfered edge 37 allows the enlarged neck section 35 to be easily inserted into the combination groove 26 of the brake disc 20, and thus the driving end 32 can be driven by a hand tool (not shown), so that the thread section 33 of the screw column 31 can be screwed into the inner thread hole 30 in the combination groove 21, and the slit 36 of the neck-expanding section 35 is elastically contracted to penetrate into the combination groove 26 and elastically expanded in the combination groove 26, so that the brake disc 20 and the fixed disc 27 are combined by the screw connection column 31 and are elastically assembled, and it can be understood that, during braking, the brake disc 20 can absorb shock or absorb shock by virtue of the elastic neck-expanding section 35 even if the brake disc 20 generates deflection and shaking, thereby achieving the substantial effect of reducing abnormal sound.
