Embodiment Construction

[0019] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0020] Best practice:

[0021] Such as figure 1 , 2 , 3, a non-powered bogie for 100% low-floor vehicles includes a frame 16 and two axles 8, and the frame 16 includes two side beams that are concave in the middle and parallel to each other and connected to two Cross members parallel to each other between the recessed portions of the side members. The side beam is a bow-shaped structure welded by weathering steel so as to reduce the height of the bottom plate; the cross beam adopts seamless steel pipe so as to reduce the overall weight of the present invention.

[0022] The two ends of the axle 8 are sequentially connected to the axle box 20, the elastic wheel 9 and the brake disc 17 from the inside to the outside, and are installed at the bottom of the side beam through the primary suspension mounts 23 and the primary suspension 21 at the front and rear ends of the axle b...

Abstract

The invention discloses a non-power bogie for a 100% low-floor vehicle. The non-power bogie comprises a framework and two axles, the framework comprises two side beams and two cross beams, the two ends of each axle are connected with axle boxes, elastic wheels and brake discs and installed at the bottoms of the side beams, the middles of the side beams sink downwards, transverse stopping parts are arranged on the inner sides of the side beams, the positions, located outside the side beams, of the two cross beams are provided with secondary suspension installation bases, the secondary suspension installation bases are provided with secondary suspensions, vertical stopping parts and vertical dampers, a magnetic track braking device is connected between the axle boxes located on the same side, the identical ends of the two side beams are respectively provided with a traction rod, the different ends of the two side beams are provided with transverse dampers and braking clamps respectively, the braking clamps are connected with energy accumulators and hydraulic braking units, and all the parts except for the traction rod are symmetrically disturbed about the central point of the framework. The non-power bogie for the 100% low-floor vehicle achieves the purpose that the lower floor surface of the vehicle is through totally, and meets the requirements of the 100% low-floor vehicle; the whole non-power bogie can rotate by 180 degrees in use and is high in flexibility.

Description

technical field [0001] The invention relates to the technical field of low-floor vehicles, in particular to a non-powered bogie for 100% low-floor vehicles. Background technique [0002] Low-floor vehicles are one of the important tools of urban rail transit. They are popular in cities for their convenience for passengers, diverse marshalling, flexible operation, and sharing of existing bus stops and road resources. The low-floor vehicle bogie, as the out-of-shape part of the low-floor vehicle, is the key component to realize low-floor vehicles. [0003] The low-floor vehicle bogie, as the out-of-shape part of the low-floor vehicle, is the key component to realize low-floor vehicles. The current low-floor non-powered bogies mostly adopt the form of independent wheel sets, but independent wheel sets have poor guidance, are easy to derail, and have complex structures and difficult manufacturing processes. [0004] Therefore, it is necessary to improve the existing low-floor ...
