Rail fastening system for fastening a rail to a rail support and assembly including such rail fastening system coupled to the rail support

摘要

A rail fastening system for fastening a rail to a rail support includes a frame member supported by the rail support and including an upper bracing portion positioned above the rail support to define therebetween a space. A stationary insulator member is positioned at a fixed location on the rail support. A plate-shaped spring blade has a first end resting on the stationary insulator member and an opposite second end supported by a movable insulator member. A wedge member is connected to the spring blade and is operable to be inserted into the space, thereby inserting the spring blade into the space with the first end of the spring blade being supported and sliding on the stationary insulator member and with the second end of the spring blade being supported on and moving the movable insulator member in the insertion direction. The wedge member is braced against the bracing portion of the frame member and causes the spring blade to deflect downwardly to press the opposite ends of the spring blade against the insulator members while the opposite ends of the spring blade are deflected or urged upwardly.
