READJUSTING DEVICE FOR PNEUMATICALLY ACTUATED DISK BRAKES, AND DISK BRAKE

摘要

Disclosed is a readjusting device (1) for a disk brake, especially a pneumatically operated disk brake, which is used for twisting and thus axially moving at least one rotary spindle (10) that is provided with internal teeth (11) composed of one or several axially extending grooves. Said readjusting device comprises an output bush (7) that is provided with external teeth which engage into the internal teeth of the rotary spindle (10) as well as a monolithic or multipart release spindle (2). Said release spindle (2) axially penetrates the readjusting device and is used for manually releasing the same. The spindle (2) is disposed and/or mounted in such a way that rotations of the spindle below a threshold speed, which are caused by vibrational stress during operation of the disk brake, are prevented. The inventive readjusting device (1) is characterized in that the spindle (2) or a part that is connected to the spindle (2) in a torsion-proof manner is also provided with external teeth (17) which engage directly into the internal teeth (11) of the adjusting spindle (10) as well.
