Description

Technical Field

[0001] The utility model belongs to the technical field of motorcycle parts, and particularly relates to a silent and flexible braking disc brake. Background Art

[0002] The disc brake, also known as the disk brake, is a common braking system and is widely used in means of transportation such as bicycles, motorcycles, and automobiles. The disc brake system mainly consists of components such as a brake disc (or disc), a brake caliper, a friction plate (or brake pad), and a hydraulic system (for hydraulic disc brakes).

[0003] However, most existing motorcycle disc brakes are prone to generate noise when braking due to friction or when the disc bends because the disc is relatively thin, and the existing disc brakes have problems such as inflexible braking force due to asynchronous contact of the brake pads on both sides.

[0004] Therefore, a silent and flexible braking disc brake is proposed to solve the above problems. Content of the Utility Model

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1 -5, a silent and flexible braking disc brake, comprising: a disc 1 and a main body 5. A vent hole 4 is provided inside the disc 1. An arc flange 2 is fixedly connected inside the disc 1. Gaskets 3 are arranged on both sides of the arc flange 2;

[0025] A fixing screw 8 is threadedly connected inside the main body 5. A side plate 9 is threadedly connected to the outer surface of the fixing screw 8. The fixing screw 8 fixes the main body 5 and the side plate 9. A hydraulic oil circuit 14 is provided inside the main body 5, and a hydraulic oil circuit 14 communicating with it is provided inside the side plate 9;

[0026] A first hydraulic cylinder 10 is fixedly connected to the outer surface of the main body 5. A first output rod 12 is slidably connected inside the first hydraulic cylinder 10. A shock-absorbing gasket 16 is fixedly connected to the output end of the first output rod 12. A second hydraulic cylinder 11 is fixedly connected to the upper surface of the main body 5. A second output rod 13 is slidably connected inside the second hydraulic cylinder 11.

[0027] The technical solution provided by this embodiment is as follows: First, an arc-shaped flange 2 is fixed at the hub. When fixing, gaskets 3 are placed at the fixing holes on both sides of the flange. After fixing in place, the main body is fixed at a preset position at the fixing plate 7. Next, the side plate 9 is fixed by fixing screws 8. After installation, observe the positions of the two carbon-ceramic brake pads 19 relative to the disc 1. The distances on both sides should be equal. After fixing, the hydraulic source is connected to the hydraulic input pipe 15, and then it can work. After braking, the hydraulic source inputs hydraulic pressure into the hydraulic oil circuit 14. Since the inner diameters of the first hydraulic cylinder 10 and the second hydraulic cylinder 11 are the same, the lengths output by the two output rods are the same. After the two output rods output a certain length, the carbon-ceramic brake pads 19 clamp the disc 1, thereby performing the braking action. During braking, the vibration generated by the carbon-ceramic brake pads 19 is isolated by the shock-absorbing gasket 16 when passing through it, avoiding the vibration from being transmitted to other positions and thus generating noise. Moreover, since the disc 1 is relatively thick and hollow inside, it is less likely to generate strain compared to a thin disc, also avoiding noise generated by accidental friction between the deformed disc 1 and the brake pads. The gaskets on both sides of the arc-shaped flange 2 can also isolate part of the vibration.

[0028] Further, a fixing plate 7 is fixedly connected to the outer surface of the main body 5, and a reinforcing rib 6 is fixedly connected to the outer surface of the fixing plate 7.

[0029] Specifically, through the arrangement of the reinforcing rib 6, it is more firmly fixed after being fixed and is not likely to be bent.

[0030] Further, a hydraulic input pipe 15 is fixedly connected to the outer surface of the main body 5, and the hydraulic input pipe 15 is communicated with the hydraulic oil circuit 14.

[0031] Specifically, through the way that the hydraulic input pipe 15 is communicated with the hydraulic oil circuit 14, the hydraulic pressure can be more evenly transmitted to the two hydraulic cylinders during hydraulic input.

[0032] Further, a steel back plate 17 is fixedly connected to the outer surface of the shock-absorbing gasket 16, a heat-insulating gasket 18 is fixedly connected to the other side of the steel back plate 17, and a carbon-ceramic brake pad 19 is fixedly connected to the other side of the heat-insulating gasket 18.

[0033] Specifically, by setting the brake pads as carbon-ceramic brake pads 19, the noise is smaller during braking, and it also has excellent performance at high temperatures.

[0034] Further, the inner diameters of the first hydraulic cylinder 10 and the second hydraulic cylinder 11 are the same, and a shock-absorbing gasket 16, a steel back plate 17, a heat-insulating gasket 18, and a carbon-ceramic brake pad 19 are also fixedly connected to the outer surface of the second output rod 13.

[0035] Specifically, the same inner diameters of the two hydraulic cylinders make the lengths output by the output rods inside them the same when the same hydraulic pressure is input.

[0036] Further, the hydraulic oil circuit 14 is arranged inside the side plate 9 of the main body 5. One end thereof is connected to the first hydraulic cylinder 10, and the other end is connected to the second hydraulic cylinder 11, and they are connected in parallel by the hydraulic input pipe 15.

[0037] Specifically, through the way of parallel connection of the oil circuits, when the hydraulic pressure is input, the hydraulic pressures received by the two hydraulic cylinders are the same, so that the two carbon-ceramic brake pads 19 can contact and clamp the disc 1 simultaneously.

[0038] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
