Abstract
The invention discloses a bogie for a low-floor vehicle. The bogie comprises a frame of a #-shaped structure, wherein rolling wheels are arranged on the left side and the right side of the frame, U-shaped grooves are formed in the middles of the left side and the right side of the frame and outwards extend to be provided with secondary spring bases, and secondary springs are arranged at the upper portions of the secondary spring bases. Swing bolsters respectively connected with the upper portions of the secondary springs are arranged on the left side and the right side, and the middles of the swing bolsters are connected with a vehicle body through central pins. The secondary spring bases are arranged at the bottoms of the grooves, and the secondary springs are arranged on the secondary spring bases, so that the heights of the secondary springs are decreased, and the heights of the swing bolsters are further decreased. Therefore, the heights of other parts connected with the swing bolsters are also correspondingly decreased, so that arrangement of the space inside the vehicle body above the bogie is promoted. In addition, due to the fact that the secondary spring bases are located at the outward extending positions of the grooves of the frame, a transverse span of the secondary springs is increased, the side roll resisting performance of the frame is improved, and the stability of the frame is further improved.
Description
Technical field
The present invention relates to technical field of vehicle, particularly relate to a kind of low floor vehicle with turning to
Frame.
Background technology

Accompanying drawing explanation
In order to be illustrated more clearly that the present invention or technical scheme of the prior art, below will be to reality
Execute the required accompanying drawing used in example or description of the prior art to be briefly described, it should be apparent that,
Accompanying drawing in describing below is some embodiments of the present invention, for those of ordinary skill in the art
From the point of view of, on the premise of not paying creative work, it is also possible to obtain other according to these accompanying drawings
Accompanying drawing.
A kind of low floor vehicle that Fig. 1 is provided by a kind of detailed description of the invention of the present invention is with turning to
The structural representation of frame；
Fig. 2 is the part-structure schematic diagram of Fig. 1.
Reference is as follows:
1 is framework, and 2 is bolster, sells centered by 3, and 4 is secondary spring, and 5 is brake clamp,
6 is side bearing, and 7 is horizontal backstop, and 8 is drawing pull bar interface, and 9 is transverse damper interface,
10 is limited block, and 11 is secondary spring base.
Detailed description of the invention
The most as described in the background section, current bogie needs the space taking in car body,
The space being unfavorable for above bogie in car body is arranged.
On the basis of the studies above, embodiments provide a kind of low floor vehicle and use
Bogie, by arranging secondary spring base at the bottom portion of groove of the framework left and right sides, two is bullet
It is equipped with secondary spring on spring base, therefore reduces the height of secondary spring, and then reduce
The height of bolster connected with secondary spring top, it is to be understood that and bolster connect its
He reduces by the height of parts the most accordingly, so that bogie is without taking the sky in car body
Between, it is thus advantageous to the layout of inside roominess above bogie.Simultaneously because at the bottom of secondary spring
Seat is respectively positioned on framework upper groove and stretches out place, increases secondary spring horizontal of the left and right sides
