Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

A disc brake disc connecting device 100 according to an embodiment of the present invention is described below with reference to fig. 1.

As shown in fig. 1, the disc brake disc connecting device 100 according to the embodiment of the first aspect of the present invention includes an injection-molded wheel hub 1, a rigid member 2, a disc brake disc 3 and a connecting member 4. The injection molding hub 1 is provided with a mounting hole 101. The injection-molded hub 1 is made of a plastic having a certain strength and a light weight.

The rigid part 2 is pre-buried in the wheel hub 1 of moulding plastics, and the at least part of rigid part 2 is located mounting hole 101, is equipped with first screw hole on the at least part of rigid part 2. The disc brake disc 3 is provided with a connecting hole, and the connecting piece 4 penetrates through the connecting hole and is in threaded fit with the first threaded hole. Connecting piece 4 is the bolt, and the dish of stopping 3 links to each other with rigidity piece 2 through the bolt, and then realizes that the dish of stopping 3 is at the installation of moulding plastics on wheel hub 1.

According to the utility model discloses dish connecting device 100 that stops through with the at least part pre-buried in the wheel hub 1 of moulding plastics of rigidity piece 2, and then the wheel hub 1 of moulding plastics relatively of rigidity piece 2 has great locking force in the axial of first screw hole and circumference. Moreover, by providing the first threaded hole on the rigid member 2, the disc brake disc 3 is rigidly-rigidly connected to the rigid member 2 via the connecting member 4, and the disc brake disc 3 has a large locking force in the axial and circumferential directions of the first threaded hole relative to the rigid member 2. From this, when the dish was stopped and is coiled 3 and receive axial force and torsion, the wheel hub 1 of moulding plastics was more difficult for taking place to warp, and the dish is stopped and is coiled 3 more difficult pine and take off, and the dish is stopped the function stability.

Note that the term "pre-embedded" as used herein means that at least a part of the rigid member 2 is embedded in a predetermined position before the final molding of the injection-molded hub 1, and the injection-molded hub 1 covers at least a part of the rigid member 2 after the molding of the injection-molded hub 1.

In some embodiments, the rigid member 2 is injection molded onto the injection molded hub 1. When the injection molding of the hub 1 is performed, the rigid part 2 is placed at a set position of an injection mold in advance, when the injection molding of the hub 1 is performed, the injection molding hub 1 covers the rigid part 2, and at least part of the rigid part 2 is located in the mounting hole 101 of the injection molding hub 1. This ensures a stable connection between the injection-molded hub 1 and the rigid part 2.

It should be noted that, in the present embodiment, the rigid member 2 is first injection-molded on the injection-molded hub 1, and then the first threaded hole is machined in the portion of the rigid member 2 located in the mounting hole 101 through the mounting hole 101. That is, the rigid part 2 is basically and completely embedded in the injection molding hub 1, so that the rigid part 2 is ensured to have larger locking force in the axial direction and the circumferential direction of the first threaded hole relative to the injection molding hub 1.

In some embodiments, as shown in fig. 1, the rigid member 2 is a connecting plate 201, and the thickness direction of the connecting plate 201 is consistent with the axial direction of the first threaded hole. Therefore, the axial size of the first threaded hole is equal to the thickness of the connecting plate 201, and after the connecting piece 4 is in threaded fit with the first threaded hole, the connection between the connecting piece 4 and the connecting plate 201 is more stable.

In some embodiments, the thickness of the connection plate 201 is 2mm to 10 mm.

Specifically, connecting plate 201 is the steel sheet, and through setting up the steel sheet thickness and not less than 2mm, effectively avoid connecting plate 201's thread to warp when dish 3 of stopping receives ultimate drawing force and ultimate torsion, guarantee the stability of dish function of stopping. Through the thickness that sets up connecting plate 201 not more than 10mm, avoid the too big transformation cost that increases disc brake dish connecting device 100 of volume and weight of connecting plate 201 from this.

Preferably, the thickness of the connection plate 201 may be 2mm, 4mm, 6mm, 8mm, 10mm, and the like.

In some embodiments, the number of the first threaded holes is plural, the connecting plate 201 is an annular plate, the axis of the annular plate is substantially coincident with the axis of the injection hub 1, and the plural first threaded holes are circumferentially distributed on the annular plate at equal intervals.

Specifically, be equipped with on the dish of stopping 3 with first screw hole one-to-one's connecting hole, pass corresponding connecting hole and with corresponding first screw hole screw-thread fit through the same bolt of quantity, guaranteed the dish of stopping 3 and the joint strength between the wheel hub 1 of moulding plastics from this. Moreover, through all establishing a plurality of first screw holes on a connecting plate 201, the degree of difficulty of moulding plastics of wheel hub 1 and rigid part 2 is lower.

In some embodiments, the number of first threaded holes is six. From this, realize the dish through six bolts and stop the installation of dish 3 on wheel hub 1 of moulding plastics, when guaranteeing that the dish stops dish 3 and the joint strength between the wheel hub 1 of moulding plastics, the dish stops that the dish 3 assembly efficiency is high.

In some embodiments, the number of the connecting plates 201 is multiple, and each connecting plate 201 is provided with a first threaded hole, and the first threaded holes are distributed at equal intervals along the circumferential direction of the injection-molded hub 1.

If the connection plate 201 is a square plate, the first threaded hole is formed at the center of the square plate. The plurality of connecting plates 201 are respectively injected at set positions of the injection hub 1, and the plurality of first threaded holes can be distributed on one end face of the injection hub 1 at equal intervals along the circumferential direction of the injection hub 1.

In some embodiments, the mounting hole 101 is a second threaded hole having an axis coincident with an axis of the first threaded hole, and the connector 4 passes through the connecting hole and is threadedly engaged with the first and second threaded holes.

Namely, when the first threaded hole on the connecting plate 201 is processed, the second threaded hole on the injection-molded hub 1 is also processed at the same time, so that the connection strength between the connecting piece 4 and the injection-molded hub 1 and the rigid piece 2 is further ensured.

In some embodiments, the ultimate drawing force of the rigid member 2 relative to the injection-molded hub 1 is greater than 360kg, and the ultimate torque of the rigid member 2 relative to the injection-molded hub 1 is greater than 12 n.m. Therefore, when the electric bicycle is braked by the disc brake function in any state, the drawing force and the torque which are applied to the connecting position of the injection molding wheel hub 1 and the rigid part 2 cannot exceed the limit value, the injection molding wheel hub 1 basically cannot deform, and the disc brake function is stable.
