Abstract

Bei dieser selbstzentrierenden Bremse (1) bleibt das Bremsmoment bei Normalbetrieb und bei Ausfall einer Bremshälfte (3) gleich. Die Bremse (1) besteht aus einem im Querschnitt U-förmigen Gehäuse (2), wobei ein Schenkel des Us einer Bremshälfte (3) entspricht. Die Bremshälften (3) sind identisch aufgebaut. Je Bremshälfte (3) ist ein aktiver Bremsbelag (4) und ein passiver Bremsbelag (5) vorgesehen. Der aktive Bremsbelag (4) wird von einer Federkraft einer Druckfeder (6) beaufschlagt. Bei Ausfall einer Bremshälfte (3) übernimmt der passive Bremsbelag (5) die Funktion des aktiven Bremsbelages (4).

In this self-centering brake (1), the braking torque during normal operation and failure of a brake half (3) remains the same. The brake (1) consists of a cross-sectionally U-shaped housing (2), wherein a leg of the Us a brake half (3) corresponds. The brake halves (3) are constructed identically. Each brake half (3) an active brake pad (4) and a passive brake pad (5) is provided. The active brake pad (4) is acted upon by a spring force of a compression spring (6). If one brake half (3) fails, the passive brake lining (5) assumes the function of the active brake lining (4).
