BRAKE RELEASE MECHANISM FOR A SPRING BRAKE ACTUATOR AND SPRING BRAKE ACTUATOR COMPRISING SUCH BRAKE RELEASE MECHANISM

摘要

Brake release mechanism (24, 124) for a spring brake actuator (2), said release mechanism comprising a brake release bolt (30, 130) having an indicator device (32, 132) comprising an indicator pin (26, 126) having a longitudinal axis (28, 128) and being at least partially accommodated in a receiving space (40, 140) of the release bolt, and a pin actuator (16, 116) for moving the indicator pin relative to the receiving space along its longitudinal axis and wherein the pin actuator comprises an indicator cap (36, 136) being configured to abut against a running nut (12, 112) for moving the pin actuator along its longitudinal axis. The indicator cap and the indicator pin are non-releasably connected to one another in their assembled state by a permanent bond (38) and/or by a permanent deformation portion (142) arranged at the indicator pin, for providing a durable connection between the indicator cap and the indicator pin.
