Description

A kind of low-floor tramcar power car bogie
Technical field
The present invention relates to tramcar bogie more particularly to a kind of low-floor tramcar power car bogies.
Background technology
100% low-floor tramcar need not set platform with it, facilitate the advantages of passenger getting on/off and enjoy great popularity. Nineteen ninety, in the world first 100% low-floor tramcar formally expose in Bremen, Germany, from this, urban tram Entered for 100% low-floor epoch.The floor level of 100% low-floor tramcar is usually 350mm or so, is conveniently multiplied Visitor, especially children, wheelchair disabled person etc. get on or off the bus.Meanwhile passenger is facilitated to move in the car, reduce get on or off the bus when Between.It can meet the freight volume demand of different cities and circuit by adjusting the organizational systems of train.Bogie is locomotive, rail electricity The important component of vehicle, subway is the critical component of its operation, guiding, load-carrying and vibration damping.The fortune of bogie and tramcar Row quality, safety and economy have substantial connection.Tramcar bogie includes the structural shape and independence of traditional wheelsets The structural shape of wheel.
Using the structural shape of traditional wheelsets, to reduce floor level, wheel uses minor radius wheel.Independent wheel turns to Frame is to cancel the axle of conventional rigid wheel pair or substituted using recessed axis bridge, and steering framing wheel sets the space that inside is vacated For floor compartment passageway, due to not having axle, left and right wheel " decoupling ", each is independently rotated around wheel center.Using only 100% low floor vehicle technical sophistication of vertical wheel system, exposes many problems, for example wheel is quickly ground in utilization Consumption, Xuan wheel periods are shorter than traditional wheelsets, and derailing tendency is higher than traditional wheelsets.Domestic 100% tramcar bogie is mostly using biography For steerage to technology, the present invention is the tramcar bogie using traditional wheelsets.
The tramcar bogie technique application range is wider, which uses the structural shape of traditional wheelsets, leads Draw motor gearbox transmission system to be placed on the outside of framework, two alternating current generators and gear-box are suspended on the two of framework along longitudinal direction respectively Side, each wheel is to respectively there is 1 motor driving.Bogie frame is located on the inside of wheel.Framework is by two symmetrically arranged curb girders and position Crossbeam composition between two curb girders, curb girder includes centrally located U-shaped frame and the end-rack for being connected to U-shaped frame both ends, horizontal U-shaped frame of the beam respectively with two curb girders is connect;Secondary suspension installation is set in curb girder;Single stage suspension is set between axle box and end-rack; Draft gear is set among crossbeam;Curb girder is located on the inside of wheel.Wheel is to including axle and the wheel set on wheel shaft both ends;Driving system System is longitudinally arranged, and including motor, gear-box, motor and gear-box rigid connection, gear-box is interior to be equipped with gear set, the output of motor Axis is connected by the conical gear of conical gear and gear-box, and the output shaft coupling of gear-box and the input shaft coupling of wheel connect It connects.The suspension installation point of drive system is located at the both sides of truck side sill, and two curb girders are equipped with the first mounting base and the second installation Seat, the first mounting base include three supporting points of the hitch point composition drive system of two hitch points and the second mounting base. Foundation brake system includes brake and the brake disc with brake cooperation, and brake disc mounting base is in axle end.It turns to and sets up It is equipped with magnetic rail braking device.
Existing bogie driving system structure is complicated, and manufacture is of high cost, and domestic tramcar manufacture accessory relies on substantially Import;Frame construction is complicated, and casting, welding requirements are high.
The technical problems to be solved by the invention are to provide a kind of novel low-floor tramcar power car bogie, energy Enough meet the space requirement of low-floor, and gearbox drive system structure can be simplified, the structure of framework can be simplified, had Independent intellectual property right, product manufacturing realize production domesticization completely.
