Abstract (en)
[origin: EP1529710A1] An automatic application hand brake apparatus is provided for automatically applying at least one brake member secured to a railway vehicle with the hand brake assembly (20). The apparatus comprises an operating member having at least one ratchet attached to a drive shaft (24) of said hand brake assembly (20). The apparatus also includes an application cylinder (320) connected to a drive arm (340) pivotally attached to said drive shaft (24) and containing and operating pawl (354) engaging said operating ratchet (350). The reciprocating motion of the drive arm (340) caused by the application cylinder (320) enables reciprocal rotation of the operating arm and furthermore causing application of at least one brake member. A control means (200) is connected to the source of the fluid pressure for initiating and regulating the supply of fluid pressure to the application cylinder (320). An additional control means (200) is connected to the source of the fluid pressure for stopping an automatic application of such brake means in case of the emergency or a reversal of the unintended activation. <IMAGE>
