연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A brake disk for a disk brake, in particular, for motor cycles or bicycles, includes a brake band of a first material which has a high heat resistance and an inner part (20) of a second material which has a lower density than the first material. The brake band and the inner part (20) each have a plurality of extensions, which in each case are arranged in pairs bordering one another. A plurality of connecting elements connect the brake band (10) to the inner part (20) by being received in recesses (13, 23) formed in the extensions. Thus, a divided brake disk has little deformation or wear in the region of the connection between the brake band and the inner part in combination with a low weight. Specifically, the recess (23) is formed in such a way that the connecting line (51) between the ends of the recess (23) is at an angle α of from 15 to 85° to the tangential direction (50).

The invention claimed is: 1. A brake disk for a disk brake comprising a brake band of a first material which has a high heat resistance and an inner part of a second material which has a lower density than the first material, the brake band having a plurality of extensions and the inner part having a plurality of extensions, with the plurality of extensions of the brake band and of the inner part arranged in pairs bordering one another, and a plurality of connecting elements connecting the brake band to the inner part, with the connecting elements received in recesses formed in the plurality of extensions to transfer force transmitted from the brake bank via the connecting elements to the inner part, wherein each recess is formed in such a way that the connecting line between ends of the recess is at an angle α of from 15 to 85° to a tangential direction, wherein the recess encloses the connecting element in an angular range of more than 180°. 2. The brake disk as claimed in claim 1, wherein the angle α is approximately 30°. 3. The brake disk as claimed in claim 1, wherein the end of the recess which is at front in a direction of rotation during forward travel is a smaller distance away from the center of the brake disk than the end of the recess which is at back in direction of rotation during forward travel. 4. The brake disk as claimed in claim 1, wherein a region of an edge of the extension which is before the recess in the direction of rotation during forward travel is at an angle β relative to the tangential direction, an end of the region section which is at the front in the direction of rotation during forward travel being a smaller distance away from a center of the brake disk than the end of the region which is at the back in the direction of rotation during forward travel. 5. The brake disk as claimed in claim 4, wherein a section of the edge of the extension which is behind the recess in the direction of rotation during forward travel is at an angle γ to the tangential direction, an end of the section which is at the front in the direction of rotation during forward travel being a smaller distance away from the center of the brake disk than that end of the section which is at the back in the direction of rotation during forward travel. 6. The brake disk as claimed in claim 1, wherein a section of the edge of the extension which is behind the recess in the direction of rotation during forward travel is at an angle γ to the tangential direction, an end of the section which is at the front in the direction of rotation during forward travel being a smaller distance away from the center of the brake disk than that end of the section which is at the back in the direction of rotation during forward travel. 7. The brake disk as claimed in claim 6, wherein the angle γ substantially corresponds to the angle α. 8. The brake disk as claimed in claim 1, wherein the angular range is approximately 200°. 9. The brake disk as claimed in claim 1, wherein the connecting elements are bolts and/or rivets. 10. The brake disk as claimed in claim 1, wherein the brake band is formed from steel. 11. The brake disk as claimed in claim 1, wherein the brake band is corrugated. 12. The brake disk as claimed in claim 1, wherein the brake band has holes in the form of slots. 13. The brake disk as claimed in claim 1, wherein the inner part is formed from light metal or a light metal alloy. 14. The brake disk as claimed in claim 1, wherein the inner part has an inner ring for fixing on a hub. 15. The brake disk as claimed in claim 1, wherein the extensions of the inner part each have a strut which is at front in a direction of rotation during forward travel and a strut which is at back in the direction of rotation during forward travel. 16. The brake disk as claimed in claim 1, wherein the extensions of the inner part each have a strut which is at back in a direction of rotation during forward travel with a rear strut of the struts of the extensions oriented to substantially lie in a braking force direction occurring during braking during forward travel. 17. A brake disk for a disk brake comprising a brake band of a first material which has a high heat resistance and an inner part of a second material which has a lower density than the first material, the brake band having a plurality of extensions and the inner part having a plurality of extensions, with the plurality of extensions of the brake band and of the inner part arranged in pairs bordering one another, and a plurality of connecting elements connecting the brake band to the inner part, with the connecting elements received in recesses formed in the plurality of extensions to transfer force transmitted from the brake bank via the connecting elements to the inner part, wherein each recess is formed in such a way that the connecting line between ends of the recess is at an angle α of from 15 to 85° to a tangential direction, wherein a region of an edge of the extension which is before the recess in the direction of rotation during forward travel is at an angle β relative to the tangential direction, an end of the region section which is at the front in the direction of rotation during forward travel being a smaller distance away from a center of the brake disk than the end of the region which is at the back in the direction of rotation during forward travel, wherein a section of the edge of the extension which is behind the recess in the direction of rotation during forward travel is at an angle γ to the tangential direction, an end of the section which is at the front in the direction of rotation during forward travel being a smaller distance away from the center of the brake disk than that end of the section which is at the back in the direction of rotation during forward travel, wherein the angle γ is greater than the angle α. 18. The brake disk as claimed in claim 17, wherein the angle γ is greater than the angle β. 19. The brake disk as claimed in claim 17, wherein substantially the angle γ corresponds to the angle β.
