Fig. 7 is a perspective view of the mounting post in the present embodiment, and fig. 8 is a perspective view of the mounting post in the present embodiment at different angles, wherein x, y, and z axes in the drawings are respectively taken as a length direction, a width direction, and a height direction of the mounting post for convenience of description.
As shown in fig. 7 and 8, the mounting post 114 is generally in the shape of a corner-cut column having a longitudinal cross-section that is "pistol-shaped". The length direction of each mounting post 114 is parallel to the axial direction of the rim 111. The mounting post 114 is an integral piece of ferrous material having a mounting portion 1141, a mating portion 1142, and a retaining portion 1143.
The mounting portion 1141 is used for mounting the anti-disc brake disc 120, which is cylindrical, and its cross section in the length direction can be regarded as being substantially composed of a rounded trapezoid and a rectangle, wherein the long side of the trapezoid is connected with the long side of the rectangle. A mounting hole 1141a is formed at one end of the mounting portion 1141 in the longitudinal direction. In this embodiment, the mounting hole 1141a is a threaded hole, and the center line direction of the threaded hole is parallel to the axial direction of the rim 111.
The fitting portion 1142 is for fitting with the rim 111, and the fitting portion 1142 extends from the other end of the mounting portion 1141 in the longitudinal direction thereof in a direction coincident with the longitudinal direction of the mounting portion 1141. One end of the fitting portion 1142 in the height direction has the same shape as the mounting portion 1141, and the other end in the height direction has a notch 1142a so that the fitting portion 1142 has a fitting surface 421 for fitting with the rim 111.
The mating face 421 includes a first contact face 4211 and a second contact face 4212.
The first contact surface 4211 is configured to contact the groove bottom 1111, and has a shape matching a side wall of the groove bottom 1111, and is substantially an arc surface.
The second contact surface 4212 is configured to abut against the rim 1113 and the bead seat 1112, and has a shape matching that of the second contact surface 4212, which is a curved surface with a relatively complex shape, and can be generally considered as including two curved surfaces, and a step 1142b is formed between the two curved surfaces (i.e. at the interface between the rim 1113 and the bead seat 1112).
The mating surface 421 has four edges, namely a first edge 421a to a fourth edge 421d. The first edge 421a contacts the bottom of the groove bottom 1111 in the circumferential direction of the rim 111, and the first edge 421a has an arc shape, and the arc shape matches the arc shape of the circumferential direction of the outer sidewall of the groove bottom 1111 near the bottom. The second edge 421b contacts the outer end of the rim 1113 in the circumferential direction of the rim 111, and the second edge 421b is curved in a shape matching the curvature of the outer end of the rim 1113 in the circumferential direction. The third edge 421c has both ends connected to one end of the first edge 421a and one end of the second edge 421b, respectively, and the third edge 421c is in contact with and substantially conforms to the bead seat 1112 and the rim 1113, and the third edge 421c is curved and has a shape matching the shape of the inner ring of the rim 111 from the bead seat 1112 to the rim 1113. Both ends of the fourth edge 421d are connected to the other end of the first edge 421a and the other end of the second edge 421b, respectively, and the shape of the fourth edge 421d matches the shape of the third edge 421 c.
Further, a boundary line 421e of both surfaces is formed between the first contact surface 4211 and the second contact surface 4212. The dividing line 421e is a rib portion of the mount 114, which is located at the interface between the bead seat 1112 and the rim 1113 when the mount 114 is disposed on the rim 111, and which has a gap therebetween.
A welded portion (which may be a weld or an electrode) between the mount 114 and the rim 111 is provided between at least one of the first edge 421a to the fourth edge 421d and the rim 111. The welding can be any one of laser welding, argon arc welding or carbon dioxide protection welding. Preferably, laser welding is employed.
Preferably, the welded portions are provided between the first edge 421a and the side wall of the groove bottom 1111, and between the second edge 421b and the outer end of the rim 1113.
Preferably, the welded portions are provided between the third edge 421c and the bead seat 1112 and the rim 1113, and between the fourth edge 421d and the bead seat 1112 and the rim 1113.
More preferably, the welded portions are provided between the first edge 421a and the side wall of the groove bottom 1111, between the second edge 421b and the outer end of the rim 1113, between the third edge 421c and the bead seat 1112 and the rim 1113, and between the fourth edge 421d and the bead seat 1112 and the rim 1113.
Preferably, the anti-disc brake hub 100 further has an additional welding portion formed by welding the mounting base 114, the additional welding portion being provided between the above-mentioned edge portion of the mounting base 114 and the boundary between the bead seat 1112 and the rim 1113, that is, when welding is performed, the welding material is caused to flow into the gap, thereby filling the gap.
Preferably, the shape of the step 1142b of the mounting base 114 is such that there is also a small gap between the step 1142b and the interface of the rim 1113 and the bead seat 1112, and there is a small opening between at least one of the third edge 421c and the fourth edge 421d and the interface, and an additional welding portion is provided between the step 1142b and the interface of the rim 1113 and the bead seat 1112, that is, at the time of welding, the welding material is caused to flow into the gap through the opening, thereby filling the gap.
The stopper portion 1143 extends from an edge portion of the mounting portion 1141 at one end thereof having the mounting hole 114a in a direction consistent with a length direction of the mounting portion 1141. The limiting portion 1142 is in an arc plate shape, the radian of the limiting portion is matched with that of the edge of the anti-disc brake disc 120, and the extending length of the limiting portion is slightly larger than the overall thickness of the anti-disc brake disc 120 and is used for being abutted against the edge of the anti-disc brake disc 120, so that the anti-disc brake disc 120 is limited.
For convenience of description, the two end surfaces in the height direction of the mounting post 114 are referred to as a first end surface 1144 and a second end surface 1145, respectively, wherein the abutment surface 11422 is in contact with the second end surface 1145.
In addition, since the mounting posts 114 and the rim 111 are made of iron and are connected by welding, the mounting posts 114 and the combination thereof have high strength, and compared with the first embodiment, the anti-disc brake hub body 110 of the present embodiment can be provided with a relatively smaller number of mounting posts 114, for example, 3 or 4 mounting posts 114, which are uniformly distributed along the circumference of the rim 111, and accordingly, the anti-disc brake disc 120 has a corresponding number of fixing holes 1221a.
Fig. 9 is an enlarged view of the inner portion of the circle D in fig. 3, and fig. 10 is a side view of the mounting post in this embodiment.
As shown in fig. 9 and 10, the mounting portion 1141 of the mounting post 114 extends beyond the rim 1113 in the axial direction of the anti-disc brake hub so that the anti-disc brake disc 120 can be mounted outside the side of the rim 111, and thus the anti-disc brake disc 120 can have a larger diameter.
