Technical field

The present invention relates to levitation train running mechanism technical field, the running mechanism of a kind of middle low speed magnetic suspension vehicle.

Background technology

Middle low speed magnetic suspension train is a kind of new traffic tool for urban passenger track traffic, has the advantages such as noise is low, accelerate and stopping power is strong, climbing capacity is strong, radius of turn is little, it is little to vibrate, comfortableness is good.Under normal circumstances, each compartment of middle low speed magnetic suspension train all uses identical running mechanism.For guaranteeing that levitation train can pass through curve track smoothly and smoothly, two ends, compartment are connected with two fixed-point type suspension racks, and middle and some portable suspension racks are connected.

Traditional fixed-point type and portable suspension rack all have air spring and slide unit at four end points of two longerons.Or bolster can be set in the middle of longeron, between bolster and car body, be provided with Z-shaped drawing pull bar simultaneously.

The parts that the running mechanism of existing middle low speed magnetic suspension vehicle has the disadvantage that one, install on suspension rack are many, and structure is complicated, and manufacturing cost is high and is not easy to regular maintenance.Two, the existence of bolster and Z-shaped draw bar is unfavorable for reducing vehicle floor height, needs bigger installing space., there is certain potential safety hazard when curve negotiating in three, the most anti-disengaging gear of slipway mechanism.Four, the poverty of movement of nodding the mistake of suspension rack of the attachment means between suspension rack effectively suppresses.

Summary of the invention

The technical problem to be solved in the present invention is: providing a kind of simple in construction, safe and reliable, production cost is low, installs and safeguards easily;Suspension rack requirements of installation space is little, and vehicle floor is low;Run the running mechanism of quick and stable middle low speed magnetic suspension vehicle.

nullThe technical solution adopted for the present invention to solve the technical problems is: the running mechanism of a kind of middle low speed magnetic suspension vehicle,Including at least two end suspension rack and at least one middle suspension rack,End suspension rack is arranged on both sides before and after middle suspension rack,End suspension rack and middle suspension rack all include two longerons that left and right is arranged、Slide unit、Air spring、Cross-tie and anti-side rolling drawing bar,Slide unit and air spring are respectively positioned on the centre position of longeron,One slide unit is set on each longeron,Slide unit is fixedly supported on longeron by air spring,Connected by cross-tie between slide unit,The end of cross-tie is hinged with slide unit by being arranged on the draw-bar seat inside slide unit,Connected by anti-side rolling drawing bar between longeron,Cross-tie and anti-side rolling drawing bar are respectively positioned on the centre position of suspension rack,The slide unit of middle suspension rack arranges the linear guides extended transversely,The slide unit of middle suspension rack is connected with train body by linear guides,Slide unit and longeron are connected by draw bar.

For improving vehicle by security during curve track, transverse stop device and anti-disengaging gear are set between slide unit and longeron, transverse stop device includes the backstop being arranged on slide unit and the limit stop traverse range stopping seat being arranged on longeron, anti-disengaging gear is the vertical steel wire rope with certain sag, one end of steel wire rope is connected on slide unit, and the other end is connected on the horizontal stopping seat of longeron.

The middle inside of longeron arranges hydraulic support device, and anti-side rolling drawing bar is connected with longeron by hydraulic support device.

Nod motion for limiting the mistake of walking mechanism, by being arranged on the anti-rubber attachment means connection of nodding of longeron end between suspension rack.

The invention has the beneficial effects as follows:

1, slide unit number reduces, and has saved manufacturing cost, it is simple to regular maintenance;

2, being provided with horizontal backstop and anti-disengaging gear between slide unit and longeron, the security of suspension vehicle curve negotiating is protected;

3, connected by cross-tie and draw-bar seat between the slide unit of middle suspension rack so that it is transverse coupling, the most certain free degree can be kept again;

4, bolster and Z-shaped drawing pull bar between car body and slide unit are cancelled, and use instead and connect between linear bearing, simplify structure, alleviate weight;

5, suspension rack installs the space minimizing needed, vehicle floor height reduction;

6, two longerons of suspension rack are connected by hydraulic supporting device by anti-side rolling drawing bar, have both improve maglev vehicle traveling comfort, ensure again can be drawn smoothly at the in emergency circumstances maglev vehicle such as dead electricity, motor failure, shift;

7, the rubber module using special construction between suspension rack connects, and reduces the motion of nodding of single suspending module, makes its motion of nodding to restrain rapidly simultaneously.
