Embodiment Construction

[0019] As shown in FIGS. 2 and 3, the rail fixing assembly according to the present invention comprises a steel base 1 above which a rail 100 is suspended by means of a pair of elastic members on which lateral clamping forces are applied through associated brackets 6 . Each bracket 6 has a bottom 61 which rests on the base plate 1 and a hole 62 through which the shoulder 3 or 4 passes upwards. The required lateral clamping force acting on the elastic member 5 is maintained by means of the relevant wedge 7 inserted between each bracket 6 and the adjacent shoulder 3 or 4, the wedge 7 is first arranged on the shoulder 3 or 4 respectively. The interlocking serrations on the opposing surfaces of 4 and wedge 7 are then held in place by a securing member 8 passing through a portion 48 of shoulder 3 or 4 . As will be described in detail below, a shoulder 4 is detachable from the base plate 1 by vertically inserting a connecting shank 42 of the shoulder 4 into a hole formed in the base...

Abstract

A railway rail fastening assembly, for suspending a railway rail (100) at discrete locations along its length above a rail foundation, comprises a pair of elastic members (5) for support the head of the rail (100), a pair of brackets (6) for applying a lateral clamping force to respective ones of the elastic members (5), a baseplate (1) having first and second shoulders (3,4), and a pair of wedge members (7), each wedge member (7) being inserted between an associated one of the shoulders (3,4) and an adjacent bracket (6) thereby to maintain the said lateral clamping force, wherein at least one (4) of the said first and second shoulders (3,4) is removable from the said baseplate (1) and is held in position on the baseplate (1) by the said lateral clamping force.

Description

technical field [0001] The invention relates to a suspension rail fixing assembly. Background technique [0002] The applicant's patent EP 0758418B relates to a railway rail fixing assembly in which the rail head is suspended in spaced positions along its length above the railway foundation. As shown in FIG. 1, in one embodiment of such an assembly, a rail head 100 is supported by a pair of resilient members 101 to which a clamping load is applied through an associated bracket 102. As shown in FIG. The required clamping load is maintained by means of associated wedges 103 which are inserted between each bracket 102 and an associated plateau or shoulder 104 which is secured to a lower rail base plate 105 which is secured to the Concrete sleeper 106 on. Such a rail fastening assembly serves to reduce vibrations and is thus advantageous, for example, in subway systems. The applicant wishes to be able to retrofit such an assembly to existing sleepers. However, this would inv...
