Title: Audible brake lining wear indicator - has pivot lever actuated by yy soe which aaa adddddvances spring loaded striker towards disc
Inventor: JUNGMANN HERMANN
IPC: F16D66/02
Filed: 1975-09-05
Abstract: The brake lining wear indicator has a striker mounted above a brake disc on a shoe holding-down spring. When wear reaches a predetermined level this is released and thrust by a spring against the disc. The punch-shaped striker (3) operates in an opening (2) in the holding-down spring (1) on the disc side, and is spring loaded (5). On the side of the holding-down spring furthest from the disc (6) pivots a double-armed lever. One lever arm (9) engages in a groove (11) in the striker to lock it clear of the disc. The other arm (10) is bent clear of the holding-down spring and towards the disc. When the predetermined amount of wear has taken place, the shoes bear against the bent portion (12), causing the lever to pivot and release the striker. Protrusions (13, 14) can be formed on the disc periphery, so that when the striker is released, they strike it, making a loud rattling noise.
