Abstract
A damping arrangement for tracks to be travelled over by rail vehicles having flanged wheels, including a) a rail, and b) an outer lateral profile of elastomer material which bears on the outer side of the rail at least in a region of a lateral outer rail head flank and in a region of an outer rail head underside, wherein the outer lateral profile has, in the region of the outer rail head underside and in the region of the lateral outer rail head flank, close to the rail, a soft region which is elastically resilient with respect to the rail head, and, in the region of the lateral outer rail head flank, remote from the rail, a substantially non-elastic hard region.
Claims13
A damping arrangement for tracks to be travelled on by rail vehicles with flanged wheels, comprising
- a. a rail, with
- i. a rail head having an outer rail head lateral flank and an outer rail head lower face,
- ii. a rail web,
- iii. a rail foot, and
- iv. with an outer side facing away from the track interior, and
- b. an outer side profile of elastomeric material, the outer side profile having a section A that bears against the outer side of the rail along the outer rail head lateral flank, and along of the outer rail head lower face, and a section B that bears against the outer wall of the rail along the rail web, wherein the outer side profile has, in section A but not section B, near to the rail, a first section being elastically compliant against the rail head with cavities in the elastomeric material extending in a longitudinal direction of the outer side profile and forming longitudinal channels running parallel to the rail, and has, in the part of section A of the profile bearing against the outer side of the rail along the outer rail head lateral flank, remote from the rail, a solid region, and wherein the elastically compliant first region and the solid second region consist of the same elastomeric material.
An outer side profile made of elastomeric material for a rail relating to tracks to be travelled on by rail vehicles with flanged wheels, wherein the rail has:
- i) a rail head having an outer rail head lateral flank and an outer rail head lower face, ii) a rail web, iii) a rail foot, and iv) an outer side facing away from the track interior, and wherein the outer side profile has a section A adapted to be applied to the outer side of the rail, along the outer rail head lateral flank, and along the outer rail head lower face, and a section B being adapted to be applied to the outer side of the rail along the rail web, and wherein the outer side profile has, in its section A, but not in its section B, a first region being elastically compliant against the rail head with cavities in the elastomeric material extending in a longitudinal direction of the outer side profile and forming longitudinal channels running parallel to the rail, the elastically compliant first region being located near to the rail when applied to the outer side of the rail, and has, in the part of its section A, and has in the part of section A to be applied to the outer rail head lateral flank, a solid second region located remote from the rail, and wherein the elastically compliant first region and the solid second region consist of the same elastomeric material.
