Embodiment Construction

[0055] Figure 1 shows a cross-sectional view of part of a common damping device known from the prior art. This figure shows the upper part of a rail 2 with a rail head 3 , which is designed here as a grooved rail. A groove 38 is rolled into the rail head 3 to accommodate the flange 13 of a flanged wheel 12, such as a tram wheel. In this way, the running rail 33 and the guide rail 34 are formed with the slot 38 in between. The rails 2 are embedded in a rigid surrounding material 19, such as concrete or asphalt. The track rail 33 has a track head 35 and the guide rail 34 has a guide rail head 36 , an outer guide rail flank 37 and a guide rail lower surface 39 . The outer profile 18 substantially filling the outer rail chamber 21 is arranged on the outer side 6 of the rail 2 , ie on the side of the rail 2 facing away from the rail interior 11 . A longitudinal rail encapsulation 17 of suitable casting material has been introduced into the joint 45 rolled into the rigid surround...

Abstract

Damping arrangement (1) for tracks to be travelled over by rail vehicles having flanged wheels (12), comprising a. a rail (2) with i. a rail head (3) which has a laterally outer rail head flank (31) and an outer rail head underside (32), ii. a rail web (4), iii. a rail foot (5) and iv. an outer side (6) facing away from the track interior (11), and b. an outer lateral profile (7) of elastomer material which bears on the outer side of the rail (2) at least in the region of the lateral outer rail head flank (31) and in the region of the outer rail head underside (32), wherein the outer lateral profile (7) has, in the region of the outer rail head underside (32) and in the region of the lateral outer rail head flank (31), close to the rail, a soft region which is elastically resilient with respect to the rail head (3), and, in the region of the lateral outer rail head flank (31), remote from the rail, a substantially non-elastic hard region (10).

Description

technical field [0001] The invention relates to a damping device for a track run by rail vehicles having flanged wheels. Background technique [0002] Damping devices for tracks with eg grooves and T-rails are basically known. Such devices usually consist of shock-absorbing profiles mounted transversely on the rails. For example, from WO 2001 / 014642 A1 a shock-absorbing profile is known which in use only partially fills the rail chamber and leaves the rail chamber open on the side facing away from the The area of ​​the damping profile on the underside of the head rests elastically and compliantly against the rail head. The damping profile provides both sound damping and electrical insulation for the grooved track. Damping devices are also known from the following documents: EP1518963B1, DE4322468A1, EP0692572A1, US5464152A, DE19646133A1, WO2001 / 083889A1, DE19706936A1, DE8811396U1, DE19939838A1 and US265816A6, US265816A1.01.01 [0003] In known damping arrangements, in pa...
