Description

Technical Field

[0001] This utility model relates to the technical field of locomotive brake discs, and particularly to a multi-plate fully ventilated brake disc. Background Technology

[0002] Disc brakes are a type of brake that uses calipers to clamp a disc to generate braking force. The principle of disc brakes is based on the Pascal principle, which amplifies the braking force and then transmits it hydraulically, causing the piston inside the caliper to push the brake pads inward to clamp the disc. Because of their strong braking power and simple structure, disc brakes are suitable for all types of vehicles.

[0003] In motorcycles, the brake discs are exposed outside the vehicle body and in contact with the air. Therefore, when the calipers use brake pads to clamp the disc, the heat generated by the friction between the brake pads and the disc can be directly dissipated through the air, resulting in good heat dissipation. However, this method of heat dissipation, which relies on the disc itself to exchange heat with the air, still has its drawbacks. For example, when motorcycles are going downhill on long slopes, they need to brake continuously for a long time to control the speed, or when they brake suddenly at high speeds, the high temperature generated by the friction between the brake pads and the disc cannot be dissipated in time through the heat exchange between the outer surface of the disc and the air. Therefore, motorcycle brake discs on the market still have heat dissipation problems.

[0004] Therefore, as in the Taiwan patent TWM492981U, there are ventilated discs on the market that have multiple slots on the inner or outer side of the brake disc. By setting these slots, the contact area with air is increased, thereby enhancing the heat dissipation effect. However, the slot design of this type of ventilated disc is a design with only a single air inlet and outlet. Therefore, when the hot air enters the slot for heat exchange, it will conflict with the cold air that is about to enter the slot in the flow direction, resulting in the heat dissipation effect not being as expected.

[0005] In conclusion, existing brake discs still have their problems and are not a good design. Therefore, the creator of this project was eager to improve and innovate them. After painstaking research, the creator finally succeeded in developing this multi-plate fully ventilated brake disc. Utility Model Content

[0006] To overcome the problems of the prior art, the purpose of this utility model is to provide a multi-plate fully ventilated brake disc that can effectively increase heat dissipation.

[0007] To achieve the above objectives, this utility model provides a multi-plate fully ventilated brake disc, mainly comprising at least one ventilated disc and two positioning discs. The ventilated disc has a first central hole at its axis, and a plurality of first ventilation grooves are provided at equal intervals around the outer edge of the first central hole. A plurality of first heat dissipation grooves extend from the outer periphery of the ventilated disc toward the axis of the ventilated disc.

The ventilated disc is provided with a plurality of first heat dissipation holes, which are distributed between the plurality of first heat dissipation grooves, the plurality of first ventilation grooves, and the first central hole of the ventilated disc.

[0008] The two positioning discs are sandwiched between the front and rear surfaces of the ventilation disc. Each of the two positioning discs has a second spindle hole that connects to the first spindle hole at the corresponding position. Each of the two positioning discs has a second heat dissipation groove that connects to the plurality of first heat dissipation grooves at the corresponding number and position. Each of the two positioning discs has a second heat dissipation hole that connects to the plurality of first heat dissipation holes at the corresponding number and position.

[0009] The first axial hole, the plurality of first ventilation slots, the plurality of first heat dissipation slots, and the plurality of first heat dissipation holes all penetrate the front and rear surfaces of the ventilation disc.

[0010] The second axial hole, the plurality of second ventilation slots, and the plurality of second heat dissipation holes all penetrate the front and rear surfaces of the two positioning discs.

[0011] The device further includes a carrier disc and a plurality of connecting components. The carrier disc is disposed in the first axial hole and the second axial holes. At least one first notch is provided between the plurality of first ventilation slots of the ventilation disc. A second notch corresponding to the position and number of the first notches is provided between the plurality of second ventilation slots of the two positioning discs.

The ventilation hole 114 is used to communicate between the plurality of first ventilation grooves 112 and the plurality of first heat dissipation grooves 113. In addition, the ventilation disc 11 is provided with a plurality of first heat dissipation holes 115 distributed between the plurality of first ventilation grooves 112, first heat dissipation grooves 113 and the first axial hole 111. The first axial hole 111, the plurality of first ventilation grooves 112, the plurality of first heat dissipation grooves 113 and the plurality of first heat dissipation holes 115 all penetrate the front surface and the rear surface of the ventilation disc 11.

[0025] The two positioning discs 12 each have a second central hole 121 at the position of the first central hole 111 of the ventilation disc 11. The two positioning discs 12 each have a plurality of second ventilation slots 122 at the position and number of the plurality of first ventilation slots on the ventilation disc 11. The two positioning discs 12 each have a plurality of second heat dissipation holes 123 at the position and number of the plurality of first heat dissipation holes 115 on the ventilation disc 11. In addition, each of the plurality of first ventilation slots 112 of the ventilation disc 11 has a first notch 116 connected to the first central hole 111. Each of the plurality of second ventilation slots 122 of the two positioning discs 12 has a second notch 124 connected to the second central hole 121. The number and position of the first notches 116 and the second notches 124 correspond to each other.

[0026] The bearing disc 2 has a shaft hole 21 at its center. The outer periphery of the bearing disc 2 corresponds to the first notch 116 of the ventilation disc 11 and the number and position of the second notch 124 of the two positioning discs 12, and the plurality of third notches 22.

[0027] In this embodiment, the multi-plate fully ventilated brake disc is assembled by clamping the two positioning discs 12 onto the front and rear surfaces of the ventilated disc 11, respectively. The second axial holes 121 of the two positioning discs 12 are respectively attached to both sides of the first axial holes 111 of the ventilated disc 11. The plurality of second ventilation slots 122 of the two positioning discs 12 are respectively attached to both sides of the first ventilation slots 112 of the ventilated disc 11. The plurality of second heat dissipation holes 123 of the two positioning discs 12 are respectively attached to both sides of the first heat dissipation holes 115 of the ventilated disc 11.
