LOCOMOTIVE UNDERFRAME BRAKE |
摘要 |
FIELD: transport.SUBSTANCE: invention relates to railway wheeled vehicles. Proposed brake comprises brake line connected with air control valve with spare tank and main braking cylinder. Piston of said main braking cylinder is coupled via rod and two-arm lever with brake shoe control lever gearing. Piston rod is furnished with lengthwise axial valve with plunger spring-loaded by expansion spring at one of its end sides. Plunger is shaped to truncated cone interacting with thrust displacing in vertical plane of braking cylinder, said thrust being fitted on rod wall through lengthwise slot. Axial channel is communicated via flexible pipeline with that feeding compressed air to braking cylinder under-piston space via check valve.EFFECT: ruled out spontaneous motion in depletion of brake.4 dwg |
