ABSTRACT:
An air-operated combination diaphragm spring brake has a tamper-resistant connection between a head (46) and a spring side of a flange case (18) which together form a spring chamber (16) housing a power spring (66). The head (46) has an annular rim (70), and the flange case has an annular flange (78) with a diaphragm (48) sandwiched therebetween. A plurality of tabs (102) on one flange rotate into L-shaped channels (94) to lock the head to the flange case with a bayonet style engagement. An alternative embodiment employs threads (112, 114) on the head and adapter flanges to seal the spring chamber. A further embodiment seals the head to a cast flange case using a threaded hoop 116 fitted over the flange case to engage the threads on the head flange.
