Problems solved by technology

[0007] (2) The collection efficiency of running vehicles such as subways and monorails decreases
At this time, if the central sheet is bent, the contact area between the collector shoe and the central sheet will become smaller and the current collection efficiency will decrease.
[0009] (3) The life of the sliding contact rail is shortened
As a result, the life of the sliding contact rail is shortened

Embodiment 1

[0060] Rail seat material: aluminum alloy (JIS A6063-T5)

[0061] Width of riveted front rail seat pedestal: 114mm

[0062] The height of the rail seat: 99mm

[0063] Width of connecting piece: 18mm

[0064] Material of sliding contact rail: stainless steel (SUS304)

[0065] The warping amplitude h of the sliding contact rail: 1.5mm±0.5mm (considering the processing tolerance)

[0066] Center piece width W1 of sliding contact rail: about 92mm

[0067] Side piece width W2 of sliding contact rail: about 14.3mm

[0068] Ratio W1 / W2: About 6.4

[0069] Width of sliding contact rail: 6mm

Embodiment 2

[0074] and with figure 1 In the same structure, the production of rigid train lines with different ratios W1 / W2 and thicknesses of sliding contact rails was also tried. As a result, when the ratio W1 / W2 is 3.0 or more and the thickness of the sliding contact rail is 5.0 mm or more, it can be confirmed that the central piece of the sliding contact rail is in contact with the rail seat on the entire surface in the width direction, and has a high flatness.

[0075] The train line of the present invention can be suitably utilized as a composite rigid body train line for subways, monorails, new transportation systems, and the like. The manufacturing method of the present invention can be suitably utilized in the manufacture of such a composite rigid body train wire.

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...
