FIELD: machine building.
SUBSTANCE: inventions group relates to machine building. The buffer contains a cylinder and installed in it one or two compression springs. The tail is made cone and is inserted in the cone counter-holes created by the pushers of the damping cartridges. The damping cartridges are installed in the buffer device back to back. Each damper cartridge contains body, cover screwed on the body and locked against loosening by the radially installed lock-screws. In the buffer under first option inside each cartridge body the multi-layer multispan corrugated ring packages are installed, they are made out of steel polished corrugated tapes "corrugation in corrugation". Between the packages the rings cut into sectors are installed, on them the multi-layer packages rest as "corrugation top to corrugation top". The pushers are also made in form of sectors. Butts between the ring sectors, pusher sectors are uniformly distributed over the circle and are located under peaks of corrugations cavities of the packages. In the buffer under the second option inside each cartridge body the elastohysteretic element is installed, it is made out of wire nonwoven fabric MR (metal rubber) made either in form of thick wall cylinder or separate sectors. On the elastohysteretic element the pusher-ring is installed, it is made out of sectors. In the elastohysteretic element is made in form of the separate sectors then the pusher sector is installed on the each element sector. Between the buffer device cover rigidly connected with casing and cartridges at spacer is installed. The buffer cylindrical part goes outside via the guide hole in the cover. End part of the buffer has boring, in which using the nut the cone billet is fixed, the billet is made out of wire material MR or tough rubber or tough polymer.
EFFECT: increased damping properties, decreasing of kickback and simplification of the buffer design.
