Abstract

A composite rigid body train line and its production method, which has a sliding contact rail sliding contact with collector shoe and a rail support for fixing the sliding contact rail which includes a central plate and a lateral plate bending ductility from two sides of the central plate, said rail support has a mounting slot embeded and riveted for fixing said lateral plate, the ratio W1 / W2 of the width W1 of the central plate and the width W2 of the lateral plate, is more than 3.0, the whole surface of the central plate is contacted with said rail support in width direction virtually, so the conjugation of the sliding contact rail and rail support is improved.

Description

technical field

[0001] The present invention relates to a composite rigid body train line utilized by subways, monorails, etc. and a manufacturing method thereof. In particular, it relates to a composite rigid body train line that can improve the adhesion between the sliding contact rail and the rail seat in a composite rigid body train line that includes a sliding contact rail that is slidably contacted by a collector shoe and a rail seat on which the sliding contact rail is riveted and fixed. Background technique

[0002] A structure in which a stainless steel sliding contact rail is riveted and fixed on an aluminum alloy rail seat is known as a rigid body train line (for example, Japanese Patent Laid-Open No. 61-143233). As shown in Figure 4 (A), the sliding contact rail 1 is a long material with a cross-sectional shape, which includes: a central piece 11 that is horizontal and in contact with the collector shoe, and a side that bends and extends from both sides of the ce...
