AIR BRAKE WITH INTEGRAL SPRING CHAMBER

摘要

An air operated combination diaphragm spring brake has a permanent, fluid tight seal provided between a spring housing (46) and a spring side of an adapter housing (18). The spring housing (46) has an integral annular shoulder (90) with an extended lip portion (89) which is formed over an annular flange (94) of the adapter housing (18). A spring diaphragm (48) is interposed between the annular flange (94) and the annular shoulder (90) to form the fluid tight seal. In a second embodiment, a tube segment 98 is provided to form an annular channel over an annular flange 94' on an adapter housing 18', and an annular flange 96 on a spring housing 46, with a spring diaphragm 48' interposed therebetween.
