Fig. 1 to 8 show a brake disc assembly according to the present utility model, which includes a disc body 100, a disc cap 110, a fastener 120, and a backing block 130. The first end of the fastener 120 is connected to the tray cap 110 and the second end of the fastener 120 is connected to the tray body 100. The head block 130 extends into the tray body 100 and the tray cap 110, respectively, and the head block 130 is provided with through holes 137 for disposing the fasteners 120.
According to the connection device of the brake disc assembly, the supporting cushion blocks 130 respectively extend to the disc cap 110 and the disc body 100, when the fastening piece 120 is fastened, part of stress on the disc body 100 is transmitted to the disc cap 110 through the supporting cushion blocks 130, so that the stress on the disc body 100 is prevented from being concentrated between the disc cap 110 and the fastening piece 120, fatigue damage of the fastening piece 120 and the disc cap 110 is reduced, and the connection strength of the brake disc assembly is ensured.
The head block 130 includes a connection portion 131 and an insert portion 134. The connection portion 131 extends at least partially into the cap 110 and is disposed to fit with the cap 110. The insertion portion 134 is fixed to the connection portion 131, and the insertion portion 134 extends at least partially to the disk body 100 and is disposed to be attached to the disk body 100. Wherein the through hole 137 communicates with the connection portion 131 and the insertion portion 134, respectively.
Optionally, the size of the spacer blocks 130 in the circumferential direction D2 of the brake disc assembly is greater than the size of the spacer blocks 130 in the radial direction D1 of the brake disc assembly, so that the spacer blocks 130 have sufficient strength in the circumferential direction D2 to carry greater stresses in the circumferential direction D2.
Further, referring to fig. 1 and 2, since the stress concentration area is formed between the cap 110 and the spacer 130, the volume of the connection portion 131 is not smaller than the volume of the insert portion 134, so that the spacer 130 can well bear the stress transferred from the disc body 100 to the cap 110. Preferably, the volume of the connecting portion 131 is larger than the volume of the embedded portion 134, so as to improve the bearing performance of the supporting pad 130.
Optionally, the connecting portion 131 includes a first edge (not shown in the drawings), which extends along the axial direction D3 of the through hole 137, and by the arrangement of the first edge, the connecting portion 131 has a stable limit relationship with the disc cap 110 along the circumferential direction D2, so that the connecting portion 131 can be better stably engaged with the disc cap 110.
The head block 130 is generally of a double-cone structure. In detail, referring to fig. 1 to 5, the connection part 131 is provided at a circumferential side thereof with a first dispersing surface 132 and two first limiting surfaces 133. When the head block 130 is mounted between the disc body 100 and the disc cap 110, the first dispersion surface 132 intersects the circumferential direction D2 of the brake disc intersecting the axis of the through hole 137, and the first dispersion surface 132 extends in the circumferential direction D2. The two first limiting surfaces 133 are intersected with a radial direction D1 of the brake disc, which intersects with the axis of the through hole 137, and the two first limiting surfaces 133 are arranged at intervals along the radial direction D1. The first dispersing surface 132 is used to carry the stress in the circumferential direction D2, while the first limiting surface 133 is used to carry the stress in the radial direction D1. While the stress in the circumferential direction D2 of the disc 100 transferred to the cap 110 through the head block 130 is much greater than the stress in the radial direction D1, it is preferable that the area of the first dispersing surface 132 is not smaller than the area of the first limiting surface 133, so that the head block 130 can better disperse the stress in the circumferential direction D2 of the disc 100 transferred to the cap 110 through the head block 130.
Further, the first dispersing surface 132 is an arc surface, and the first dispersing surface 132 extends in the circumferential direction D2 when the head block 130 is mounted between the tray body 100 and the tray cap 110. And two first limiting surfaces 133 are respectively located at two sides of the first dispersing surface 132 for limiting the space between the supporting pad 130 and the cap 110 in the radial direction D1.
In particular to the insert 134, referring to fig. 2 and 5, the insert 134 includes two second dispersion surfaces 135 and two second stop surfaces 136. When the backing block 130 is mounted between the disc body 100 and the disc cap 110, the two second dispersing surfaces 135 are both intersected with a circumferential direction D2 of the brake disc intersecting the axis of the through hole 137, and the two second dispersing surfaces 135 are arranged at intervals along the circumferential direction D2, and the second dispersing surfaces 135 are used for dispersing stress transferred to the backing block 130 by the disc body 100 along the circumferential direction D2. The two second limiting surfaces 136 intersect with a radial direction D1 of the brake disc intersecting with the axis of the through hole 137, and the two second limiting surfaces 136 are arranged at intervals along the radial direction D1, and the second limiting surfaces 136 are used for dispersing stress transferred from the disc body 100 to the supporting cushion block 130 along the radial direction D1.
And the stress in the circumferential direction D2 transmitted to the head block 130 by the disk body 100 is much greater than the stress in the radial direction D1. Preferably, the area of the second dispersion surface 135 is larger than the area of the second limiting surface 136, so that the lip 130 can better bear the stress transferred from the disk body 100 in the circumferential direction D2.
Optionally, the second dispersion surface 135 is an arcuate or partially tapered surface, increasing the contact area of the lip 130 with the disk 100 in the circumferential direction D2 and lip 130. Correspondingly, the second limiting surface 136 is a bevel or a bevel, which increases the area of the second dispersing surface 135, so as to disperse the stress transferred by the disc 100 along the radial direction D1.
Referring to fig. 2 and 5, along the circumferential side of the head block 130, two second dispersion surfaces 135 and two limit surfaces are alternately disposed, and a second edge 138 is disposed between the second dispersion surfaces 135 and the second limit surfaces 136. The second edge 138 extends in the axial direction D3 of the through hole 137, and if the second dispersion surface 135 is a beveled surface or a beveled conical surface, the second edge 138 is disposed obliquely with respect to the axial direction D3. The provision of the second edge 138 allows for a better engagement of the insert 134 to the tray 100.
Referring to fig. 3, the fastener 120 includes a shank 121, a screw head 122, and a nut 123. The rod 121 is inserted into the supporting pad 130 through the through hole 137, a first end of the rod 121 is inserted into the tray cap 110, and a second end of the rod 121 is inserted into the tray 100. The screw 122 is disposed at one of the first end and the second end of the rod 121. The nut 123 is sleeved to the other of the first end and the second end of the rod 121, and the nut 123 is in threaded connection with the rod 121. When the nut 123 is screwed, the screw head 122 and the nut 123 abut against the disc body 100 or the disc cap 110, respectively, so that the disc body 100 and the disc cap 110 are restrained in the axial direction D3, so that the supporting cushion block 130 abuts against the disc body 100 and the disc cap 110, respectively, and stress on the disc body 100 is transferred to the disc cap 110, and stress between the fastener 120 and the disc cap 110 is dispersed.
Further, the tray body 100 is spaced apart from the tray cap 110 along the axial direction D3, and the supporting pad 130 is located between the tray body 100 and the tray cap 110, so as to prevent sliding wear caused by contact between the tray body 100 and the tray cap 110. Referring to fig. 6 to 8, the disc body 100 is provided with a first groove 101, and the first groove 101 is engaged with the insert 134 such that an inner surface of the first groove 101 is entirely engaged with the insert 134.
