APM-120 SHOCK ABSORBER FOR RAILWAY TRANSPORT

摘要

Use: in railway transport for the production of combined frictional-polymeric shock absorbers. Essence: the shock absorber consists of a body containing a pressing cone, movable friction plates and immovable friction plates with wear-resistant elements, friction wedges and a support unit. The friction wedges are brought into contact with a support plate which is supported on the support unit. The support unit consists of elastomeric elements which are symmetrical relative to an axis and are divided by metal plates. The support element is movably fitted onto a central bolt arranged in the body. The elastomeric elements are barrel-shaped. The dividing metal plates are in the form of flat discs. A guiding bushing attached to a projection on the bottom of the body is mounted on the dividing metal plate which is arranged close to the bottom of the body. Regulating plates are additionally mounted together with the dividing metal plate, which is arranged close to the bottom of the body, in a defined quantity depending on the specific value of the pretensioned length of the shock absorber. Technical advantages: stabilizing the power characteristics, increasing the energy capacity and simplifying the construction of the shock absorber.
