<p>#CMT# #/CMT# The joint has two elastomer arms (5) forming cylindrical sectors (4) with a symmetry plane, where the cylindrical sectors are made of rubber. The arms are bonded to curvilinear contour portion of a central axle. Two abutments are housed in two spaces (8), respectively and comprise another symmetry plane that is perpendicular to the symmetry plane of the arms. Each abutment includes an abutment part (2) made of a rigid material, where the abutment part is spaced apart from an outer tube (3) when the joint is at rest. #CMT#USE : #/CMT# Perforated joint for a drive connecting rod that forms a part of a body-bogey drive device for a rail vehicle (claimed) e.g. train. #CMT#ADVANTAGE : #/CMT# The elastomer arms provide high degree of flexibility in a train travel direction for ensuring comfort and filtering noise, and provide a high degree of stiffness in the train travel direction under strong radial stress. The elastomer arms provide a high degree of stiffness in a vertical direction. The abutments permit carrying out additional functions in a reduced volume. The joint permits carrying out contacts between the abutment part and the outer tube by a rigid part made of metal, so as to avoid rapid wear by abrasion. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a transversal sectional view of a perforated joint. 2 : Abutment part 3 : Outer tube 4 : Cylindrical sectors 5 : Elastomer arms 8 : Spaces.</p> |
