The safety device of vehicle

Technical field

The present invention relates to the safety device of vehicle, in detail, relate to and make guiding device that wheel do not deviate from from the main line track and the vehicle that makes derailing not escape into guiding device outside the track.

Background technology

The present invention relates to make the device that vehicle can safety traffic, in detail, is guiding device that wheel is not deviate from from the main line track, i.e. so-called anti-derailing guider and make the vehicle of derailing not escape into guiding device outside the track, be so-called safety track device.

Therefore at first anti-summary of derailing guider and safety track device is described below, then the relation of railway maintenance with anti-derailing guider and safety track device described.

(1) anti-derailing guider

For example when train under the situation of travelling on the curve track etc., as shown in figure 26, normally the ways that wheel 101 will not be led from main line track 102 with deviating from is parallel to main line track 102 and is disposed in the interorbital.An example that utilizes the anti-locking mechanism of derailing that this ways forms as shown in figure 27.In Figure 27, with main line track 102 abreast (on the vertical direction of paper) configuration ways 103, fastening across cushion block (block) 104 and packing ring 105,106,107 usefulness bolts 108 and nut 109 and bolt 110 and nut 111, to form the structure of supporting ways 103.This ways 103 is anti-derailing guiders.Also have, possess many group bolt nut fastening structures on the vertical direction of paper.
