| 摘要 |
A brake actuator assembly (40) for a railway vehicle braking system comprises a flexible elastomeric member (50) directly and sealably attached to a mounting member (80) employed for attaching the brake actuator assembly to the rigid structure of a braking system and to a push rod member (32) connected to the control linkage. The brake actuator assembly is connected to a source of fluid under pressure enabling inflation of the flexible elastomeric member and initiation of a braking sequence of the railway vehicle braking system. The brake actuator assembly of the present invention allows for improved control of the brake shoe forces including visual travel measurement indication which is especially desirable during light load conditions. Currently used brake assemblies employing cylinder type actuators may be retrofitted with the brake actuator assembly of the invention.
