Description

brake disc

The invention relates to a vehicle component, in particular to a brake disc.

Disc brake is a braking mechanism widely used in vehicles. It mainly installs a disc on the wheel, and then uses a caliper operated by a hydraulic mechanism. When the user operates, the caliper brakes from the opposite sides of the disc. Side clamping is used to achieve the purpose of slowing down or even stopping the wheel.

However, considering that the components of the caliper that clamps the disc will inevitably have tolerances during manufacturing and assembly, when the caliper is clamped from opposite sides of the disc, there will inevitably be differences between the two. In addition, the slight difference in the structure of the brake pads and the slight difference in force on both sides prevent the brake pads from fully engaging the disc from the opposite sides, thus affecting the braking performance and even affecting the stability of the vehicle during braking. .

Therefore, the purpose of the present invention is to provide a brake disc that can optimize braking performance and stability.

Therefore, the new brake disc includes an outer unit, an inner unit, and a floating unit connected between the outer unit and the inner unit and used to enable relative movement between the outer unit and the inner unit.

The outer unit includes an inner ring that defines an inner space, an outer ring that is radially spaced apart from the inner ring, and a plurality of outer rings that protrude radially from the inner ring toward the inner space. Each of the outer mounting parts defines an outer positioning groove with an opening facing inward.

The inner unit includes a plurality of inner mounting parts arranged at intervals around each other and respectively aligned with the outer mounting parts, and a plurality of connecting parts respectively connected between the adjacent inner mounting parts. Each inner mounting portion is spaced apart from the respective outer mounting portion by a certain margin, and defines an inner positioning groove with an opening facing outward. It is defined that each inner positioning groove and the respective outer positioning groove together form a mounting hole, and each mounting hole is composed of two arc edges located at opposite ends along the radial direction, and two arc edges connected to each other. The two opposite ends are defined by the force-bearing edges of two straight line segments parallel to each other.

The floating unit includes a plurality of fixing members respectively provided in the mounting holes. Each of the fixing parts has a penetrating portion disposed in the mounting hole and spaced apart from the arc edges and the force-bearing edges by a certain gap, and a set is connected to the penetrating portion for connecting with the The penetration portion jointly locates the assembly portion of the outer unit and the inner unit.

The function of the present invention is that the outer unit and the inner unit can use the margin gap and the reserved gap to produce slight relative movement, thereby cooperating with the actuation of the brake caliper to ensure that the unit is clamped by the opposite sides. The components of the new brake disc can evenly and stably press against the new brake disc. While achieving optimized braking performance and stability, the force-bearing edge of each mounting hole is also between the outer unit and the When relative movement occurs between the inner units, the corresponding force when the fixed component is in contact with the solid structure is dispersed to avoid damage to the specific structure caused by concentrated force, thus effectively extending the service life of the new brake disc.

Referring to Figures 1 and 2, an embodiment of the new brake disc is shown. This embodiment includes an annular outer unit 1, an annular inner unit 2 disposed inside the outer unit 1, and an annular inner unit 2. The floating unit 3 is connected between the outer unit 1 and the inner unit 2 and is used to cause relative movement between the outer unit 1 and the inner unit 2. It should be noted first that this embodiment is used with a brake caliper, so that the brake caliper clamps the outer unit 1 of this embodiment from opposite sides, so that this embodiment cannot rotate with the wheel. This achieves the braking effect.

The outer unit 1 includes an inner ring 11 surrounding an inner space 110 , an outer ring 12 radially spaced apart from the inner ring 11 , and a plurality of inner rings 11 radially oriented toward the inner space. The space 110 has a protruding outer mounting portion 13 and a plurality of slots 14 extending inwardly from the outer ring 12 . Specifically, the outer unit 1 is a ring-shaped metal sheet surrounding the inner space 110 located in the center. The outer mounting portions 13 define a plurality of circumferentially spaced grooves 139 at intervals, and each of the outer mounting portions 13 defines an outer positioning groove 130 with an opening facing inward.

The inner unit 2 includes a plurality of inner mounting parts 21 arranged at intervals around each other and respectively aligned with the outer mounting parts 13 , and a plurality of inner mounting parts 21 respectively connected between the adjacent inner mounting parts 21 and arranged in a radial direction. The connecting portions 22 respectively extend into the grooves 139 . The inner unit 2 is preferably made of metal with strong rigidity to withstand the external force exerted by the brake caliper in practical applications. Each inner mounting portion 21 defines an inner positioning groove 210 with an opening facing outward.

Referring to FIG. 3 , each inner mounting portion 21 is separated from the respective outer mounting portion 13 by a margin d. It is defined that each inner positioning groove 210 and each outer positioning groove 130 together form a mounting hole 50, and each mounting hole 50 is composed of two arc edges 501 located at opposite ends along the radial direction, and two connected to each other. The opposite ends of the arc edges 501 are defined by two force-bearing edges 502 that are parallel to each other and are straight lines. Among them, the arc edges 501 and the force-bearing edges 502 of each mounting hole 50 generally form a long axis extending in the radial direction, but there are two force-bearing edges 502 parallel to the long axis. Oval-like shape.

Referring back to FIG. 1 and in conjunction with FIG. 3 , the floating unit 3 includes a plurality of fixing members 31 (only one is shown in FIG. 1 ) respectively disposed in the mounting holes 50 . In this embodiment, six fixing members 31 are used. The fixing members 31 are arranged at angular intervals. Each of the fixing members 31 has a penetration portion 311 disposed in the mounting hole 50 and spaced apart from the arc edges 501 and the force-bearing edges 502 by a gap S, and a group connected to the penetration portion. The portion 311 is used to position the assembly portion 312 of the outer unit 1 and the inner unit 2 together with the penetration portion 311 . The shape of the penetration portion 311 of each fixing member 31 is generally adapted to fit the individual mounting hole 50 to present the same but slightly smaller shape as the mounting hole 50 . The respective assembly portion 312 is assembled to the penetration portion 311 from the opposite side, thereby completing the installation of the fixing member 31 .

It should be noted that since the outer unit 1 and the inner unit 2 are both made of metal, considering that the outer unit 1 and the inner unit 2 are bound to generate heat due to friction during operation, the outer unit 1 The slots 14 and the margin gap d between the outer unit 1 and the inner unit 2 can form a margin space for thermal expansion of the outer unit 1 and the inner unit 2, so that this embodiment can It can still continue to operate normally even when it heats up and expands due to long-term operation.

Referring to Figures 4 and 5 in conjunction with Figure 2, in this embodiment, as the wheel rotates, when the corresponding caliper operates to clamp the outer unit 1 of this embodiment, the floating unit 3 does not move the outer unit 1 The characteristics of complete locking between the outer unit 1 and the inner unit 2, combined with the pre-reserved margin gap d and the reserved gap S, will cause a slight relative movement between the outer unit 1 and the inner unit 2, thereby ensuring The components of this embodiment (usually brake pads) clamped by opposite sides can press this embodiment evenly and stably to achieve the purpose of optimizing braking performance and stability. As shown in Figure 5, the force-bearing edge 502 of each mounting hole 50 effectively disperses the force compared to a single point when relative movement occurs between the outer unit 1 and the inner unit 2. Correspondingly, the force received when the fixing member 31 is in contact with the physical structure can avoid damage to the specific structure caused by concentrated force, thus effectively extending the service life of this embodiment.

To sum up, this embodiment of the new brake disc can cause a slight relative movement between the outer unit 1 and the inner unit 2 when a force is applied, thereby ensuring that the components of this embodiment are clamped from both sides. It can be clamped stably to optimize the braking performance. At the same time, the force-bearing edge 502 of each mounting hole 50 can effectively disperse the force when the fixing member 31 contacts the physical structure to avoid the concentration of force causing specific problems. The structure is damaged, thus effectively extending the service life of this embodiment. Therefore, the purpose of this new type can indeed be achieved.

However, the above are only examples of the present invention, and should not be used to limit the scope of the present invention. All simple equivalent changes and modifications made based on the patent scope of the present invention and the content of the patent specification are still within the scope of the present invention.
