Safety when passing through curve track for improving vehicle, transverse stop device and anti-detaching gear are set between slide unit and the longeron, transverse stop device comprises the backstop that is installed on the slide unit and the limit stop transverse shifting scope stopping seat that is installed on the longeron, anti-detaching gear is vertical steel rope with certain sag, one end of steel rope is connected on the slide unit, and the other end is connected on the horizontal stopping seat of longeron.
The middle inside of longeron arranges hydraulic support device, anti-sidewinder pull bar and is connected with longeron by hydraulic support device.
Be the mistake motion of nodding of restriction traveling gear, between the suspension rack by being installed in the anti-rubber connecting device connection of nodding of longeron end.
The invention has the beneficial effects as follows:
1, the slide unit number reduces, and has saved manufacturing cost, is convenient to daily attention;
2, be provided with horizontal backstop and anti-detaching gear between slide unit and longeron, the safety of suspension vehicle curve negotiating is protected;
3, be connected with draw-bar seat by lateral connecting rod between the slide unit of middle suspension rack, make its transverse coupling, can keep certain separately degree of freedom again;
4, the bolster between car body and the slide unit and Z-shaped drawing pull bar are cancelled, and use instead between the linear bearing to connect, and simplified structure has alleviated weight;
5, suspension rack is installed the space minimizing that needs, and the vehicle floor height reduces;
6, two longerons of suspension rack are sidewindered pull bar and are connected by hydraulic supporting device by anti-, have both improved the maglev vehicle traveling comfort, guarantee again dead electricity, motor inefficacy etc. in emergency circumstances maglev vehicle can be drawn smoothly, be shifted;
7, adopt the rubber module of special construction to connect between the suspension rack, reduced the motion of nodding of single suspending module, its motion of nodding can be restrained rapidly.
