Patent DE-2427694-A1 (DE)
Title: Friction block for disc brakes - has sealing ring fitting round block at point of fixing in plate recess
Inventor: DOUSSIER HEINZ DIPL ING
IPC: B29C37/00
Filed: 1974-06-08
Abstract: The carrier plate has at least one recess for the brake block and this has no friction material on the face away from the block. The advantage of the design is that a simple device - a sealing lip - allows the friction material to project from the edge of the recess. This is additional to the main patent which has a holding ring with inclined cross section. The sealing ring (3a, 3b) has only one tenth of a millimetre projection towards the centre of the recess. The ring can be made from a spring and the recess is formed by a stamping machine.
