Description
Technical field
The present invention relates to tramcar（Urban track traffic）Field, and in particular to a kind of with low-floor and floor high
Vehicle frame.
Background technology
Tramcar as track traffic important component, because of the spy such as its energy-conserving and environment-protective, safe and reliable, cheap
Point, is used widely in many countries.70% low-floor tramcar mainly includes wheel assembly（Bogie）And its top sets
Standby two large divisions, top equipment is mainly connected by bicycle frame device with wheel assembly.Because bicycle frame device will be kept away wheel assembly
Allow, so bicycle frame device includes floor high and low-floor, generally used between rail vehicle and be hinged body construction.It is existing to be hinged
It is most in the middle of system that for upper and lower two sets of oscillating bearings are constituted, its complex structure, parts machining technique and required precision are higher, and
Install and safeguard inconvenient.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of light, firm and reliable connection with simple structure, weight
