FIELD: transport. ^ SUBSTANCE: invention relates to railway transport, particularly to disk-type brakes. Proposed disk brake consists of casing, friction linings, shoes and braking disk. Said casing is arranged on spring frame of vehicle with jaw-type parallelogram mechanism. Braking disk is fitted on vehicle wheel pair axle. Brake cylinder suspension is arranged on brake casing to translate and rotate thereon and consists of four elements. Journal, rod and spring are coupled with casing and brake cylinder by hinge pins. Moving support represents a frame made up of two-plates, two posts, two axles and four springs and can move along disk brake guide holes. Hinge pins pass through support holes, said pins coupling said support with jaw-type parallelogram mechanism and making points of bearing of the levers. Jay-type parallelogram is formed by moving support, short levers of jaw parallelogram, rockers and tie rods, and is secures at its apices by higher pins. U-like plate spring is secured to every rocker with the help of screw, spring flexible ends thrusting against appropriate shoe. ^ EFFECT: higher reliability, longer life, efficient braking, simplified lining replacement. ^ 6 dwg |
