Title: Automatic brake adjusting unit for working piston - operates according to a ratchet principle with adjusting nut on threaded spindle
Inventor: REINARTZ HANS-DIETER
IPC: F16D65/56
Filed: 1974-06-20
Abstract: The unit is particulary designed for a brake cylinder of a brake drum with two working pistons. One piston is firmly connected to the threaded spindle with the adjusting nut which is supported against the second piston. The former piston has a coaxial extension with an inner wall rigidly connected to a pawl element (10) having two catches (11, 12) with which it engages in the saw blade-like teeth (7) of a pinion (6) on the adjusting nut. As the former working piston moves it also carries along the pawl element. After a certain length of travel the inclined surface on the projection of the pawl element engages with the teeth so that the pinion rotates. In this way the adjusting nut is also turned. If the rotation proceed far enough, the locking catch (12) engages with a subsequent tooth so that an adjustment is effected but a return rotation of the pinion or nut is prevented.
