Composite-rail formed by pushdown the P-main-rail with pushdown-device against the P-auxiliary-rail

A composite-rail formed by pushdown the P-main-rail with pushdown-device against the P-auxiliary-rail, hereinafter referred to as composite-rail, and the characteristic of the composite-rail is that it consists of pushdown type main-rail, pushdown type auxiliary-rail and pushdown-device, among which,

• pushdown type main-rail hereinafter referred to as P-main-rail, pushdown type auxiliary-rail hereinafter referred to as P-auxiliary-rail,
• The P-main-rail is the steel rail that runs the wheel, it's characterized is that it have a number of downforce receiver, From the cross-section, the P-main-rail is composed of a rail-head(11) and a rail-body(10).
• The P-auxiliary-rail. it is a special shape channel steel made of the whole material, the rail-body(10) is enveloped and fastened in it, its characteristic is that its position-plates(22) have a number of downforce generator,
• The P-auxiliary-rail. is composed of a bottom-plate(23) and two symmetrical upward position-plates(22). The position-plates(22) is actually a pair of special joint bar. The bottom-plate(23) and two position-plates(22) form a position-groove(20) which upward opening, and the rail-body(10) is enveloped and fastened in it;
• Fasten the P-auxiliary-rail(2) on the sleeper so that the P-main-rail is positioned on the sleeper;
• The pushdown-device comprises a pushdown-rod, a downforce generator on the P-auxiliary-rail and a downforce receiver on the P-main-rail. The downforce generator makes the pushdown-rod produce downforce and presses the downforce receiver, and pushdown the downforce receiver, to pushdown the P-main-rail against the P-auxiliary-rail and form composite-rail
