Description
Technical field
The present invention relates to the bogie technique field of wheel track vehicle, especially, relate to a kind of trailer bogie for metric rail.
Background technology
Low-floor light rail vehicle is a kind of novel track vehicle that is mainly used in city traffic, and the distance of car body floor and rail level generally is no more than 40cm.The core technology of low floor light rail train is independently rotating wheel bogie.
So-called independently rotating wheel is meant that left and right wheels can rotate around axletree mutually independently of one another on the same axis, and the wheel that has relative motion between the wheel shaft is right.Because two wheels of independently rotating wheel bogie are independent rotation separately, so there is not vertical creep power in it, but can not produce hunting yet, the effective operation stability of support vehicles, and can pass through the less orbital curve of radius, have abrasion less, noise is little, in light weight and easily realize advantage such as low floor, is fit to the needs of urban light rail traffic more.
The prior art such as the patent No. provide a kind of independent wheel bogie that is used for urban low-floor light rail car for the patent document of ZL200720094542.5, the structural representation of prior art one independent wheel bogie as shown in Figure 1, comprise framework, by one is the independent axle bridge that rubber spring is connected with framework, supporting two of car body is steel spring and rubber spring, curb girder, end carriage is a spill, be arranged with the cambered axle pull bar between independent axle bridge and the framework, the framework outside is provided with the drawing pull bar of two symmetries, framework is provided with vertical damper for four jiaos, skew symmetry is provided with lateral damper on two end carriages of framework, independent axle bridge end is provided with hydraulically powered brake unit, two two is to be provided with vertical backstop between the steel spring, and the curb girder inboard of framework is provided with horizontal backstop.
Above-mentioned bogie truck has adopted the two-stage suspension, by a framework with two independently the axle bridging be connected into one, the integral structure more complicated; The traditional hydraulic braking mode structure that is adopted is more complicated also.In addition, secondary suspension is that four steel springs directly support car body, and the suspension behavior of steel spring is relatively poor.Whole bogie truck occupation space is bigger, is not suitable for the needs of meter path road and narrow car body.
Structural representation with reference to two independently rotating wheel bogies of the prior art shown in Fig. 2, the patent document of prior art such as patent No. ZL200620024464.7 also provides a kind of low-floor light rail vehicle independently rotating wheel bogie, comprise framework, independent wheel is right, central mounting, disc brake unit and pipeline thereof, purchasing car independently takes turns right rubber elastic wheels and spool is connected by outer cone bearing and female cone bearing and end, wherein outer cone bearing and female cone bearing cone are fitted on this end axle, the outer ring is press fit on this rubber elastic wheels, described end axial compression installs on the U profile shaft beam, and this U profile shaft Liangqi is provided with the auxiliary hole with its one piece casting; Constitute the right disk-braking press mounting of independent wheel to brake axle, this brake axle is affixed by bolt and rubber elastic wheels.
This bogie truck also is to have adopted the two-stage suspension, by a framework with two independently the axle bridging be connected into one, the structure more complicated; The traditional disc type brake mode structure that adopts is more complicated also.In addition, secondary suspension is that two air bellows directly support car body, and structural stability is poor.In addition, it is too small and cause traversing amount limited that air bellow is seated at the right transverse pitch of framework central authorities and wheel.Whole bogie truck occupation space is bigger, is not suitable for the needs of meter path road and narrow car body.
In a word, existing low floor independently rotating wheel bogie exists complicated integral structure, brake system structure complexity, the secondary suspension structural stability is poor, integral structure takes up room greatly, only be adapted at moving on the circuit of standard gauge, can not satisfy the shortcomings such as needs of meter path road and narrow car body.
