Description

剎車碟盤brake disc

本發明係與剎車碟盤有關。The present invention relates to brake discs.

常見的剎車機構可以分成鼓式剎車及碟式剎車，鼓式剎車係屬於封閉式系統，鼓式剎車包含有剎車鼓及剎車蹄片機構，剎車時係透過向外撐張開的剎車蹄片來與剎車鼓之內面接觸；而碟式剎車係屬於開放式系統，碟式剎車主要由剎車碟盤及卡鉗所組成，剎車時係透過卡鉗向內夾住剎車碟盤，故碟式剎車之散熱效能優於鼓式剎車。Common brake mechanisms can be divided into drum brakes and disc brakes. Drum brakes are a closed system. Drum brakes include brake drums and brake shoe mechanisms. It is in contact with the inner surface of the brake drum; while the disc brake is an open system, the disc brake is mainly composed of the brake disc and the caliper. When braking, the brake disc is clamped inward through the caliper, so the heat dissipation of the disc brake Efficiency is better than drum brakes.

然而，碟式剎車於剎車過程中依然會產生摩擦高溫，故需要在剎車碟盤上設計散熱結構來進一步輔助散熱，常見的方式係在剎車碟盤進行打孔、劃線，但過度打孔、劃線又容易影響盤體結構剛性而產生裂痕或抖動。However, disc brakes will still generate frictional high temperature during the braking process, so it is necessary to design a heat dissipation structure on the brake disc to further assist heat dissipation. The common method is to drill holes and mark lines on the brake disc, but excessive drilling, Scribing lines can easily affect the structural rigidity of the disc body and cause cracks or vibrations.

因此，有必要提供一種新穎且具有進步性之剎車碟盤，以解決上述之問題。Therefore, it is necessary to provide a novel and progressive brake disc to solve the above problems.

本發明之主要目的在於提供一種剎車碟盤，可以有效地進行散熱且確保本身具備有足夠的結構剛性以供使用。The main purpose of the present invention is to provide a brake disc that can effectively dissipate heat and ensure sufficient structural rigidity for use.

為達成上述目的，本發明提供一種剎車碟盤，包括：一剎車盤、複數第一穿槽及至少一第二穿槽。該剎車盤包含有二剎車面及一外環側面，該外環側面橫向地連接於該二剎車面之間；該複數第一穿槽呈間隔配置地凹設於該外環側面；該至少一第二穿槽凹設於該外環側面，該至少一第二穿槽之至少部分係小於該第一穿槽。To achieve the above object, the present invention provides a brake disc, comprising: a brake disc, a plurality of first slots and at least one second slot. The brake disc includes two braking surfaces and a side surface of an outer ring, and the side surface of the outer ring is transversely connected between the two braking surfaces; the plurality of first through grooves are recessed on the side surface of the outer ring at intervals; the at least one The second through groove is recessed on the side of the outer ring, and at least part of the at least one second through groove is smaller than the first through groove.
