Description
Technical field
The present invention relates to train bogie, particularly low-floor tramcar bogie.
Background technology
100% low-floor modern tram uses without bow by sophisticated technologies such as stream, super capacitors, and floor is away from rail level about 38 centimetres, it is not necessary to platform, and maximum freight volume is 6 to 8 times of bus.Vehicle can use accumulator and super capacitor parallel hybrid power, it is provided that completely without net-fault scheme, climbing capacity is strong, min. turning radius about 20 meters, city existing road gets final product laying-out, environmental protection, low noise, is one of state-of-the-art Traffic Systems in the world today.
100% low-floor modern tram contains bogie and car body, and for 100% low-floor modern tram, the purpose of low-floor to be realized, the design of bogie is the most important, there is also many different structures for different requirements.As disclosed a kind of 100% low-floor light rail vehicle mechanism of independent wheel power truck in the patent documentation that Application No. 201010520644.5 publication date is on February 23rd, 2011, and specifically disclose it and include framework, axle bridge forms, primary spring, secondary spring, two is vertical, lateral damper, duplex pull rod haulage gear, elastic suspension motor longitudinal driving mechanism, hydraulic brake unit, truck side sill is outwardly cantilevered, two short axles are supported by bearing unit and connect an elastic wheel the most respectively, axletree is made up of two short axles, two wheels of bogie the same side are fixed on motor driving shaft, motor and two gear-boxes couple；Brakes becomes one with traction electric machine, and four two is that vertical damper is located on the corner of framework；Two is the end positions that lateral vibration absorbing device is located at framework；Parallel double-draw rod trailer system is located at the inner side of framework.Said structure uses high-intensity welding framework and independent axle bridge composition, primary spring rational in infrastructure and secondary spring, optimal two are vertical and lateral damper, and use parallel double-draw rod traction apparatus and the elastic suspension motor zigzag tread patterns of interior traction, use the hydraulic brake unit integrated with traction electric machine, be truly realized car body 100% low-floor requirement.This bogie uses the technology of Longitudinal data transmission, the only mechanism of independent wheel of side has driving power, and opposite side belongs to passive rotation, relatively it is difficult to ensure the mechanism of independent wheel synchronous rotary of card both sides, therefore, train is in operation and can be difficult to ensure that the stationarity of train operation because driving force is uneven, it is difficult to ensures wheels centering on straight line, the phenomenon of flange wear easily occurs；Additionally, although said structure have employed short axle mechanism of independent wheel structure, and have employed axle bridge composition, but axle bridge composition vertical direction generally within short axle below, when light rail car is along curve motion, axle bridge composition occurs angle to change with mechanism of independent wheel the most simultaneously, and the guidance capability of mechanism of independent wheel is poor, bogie turn to freedom not good enough, the noise of operation is bigger than normal.
The most also there is the bogie connected by two side wheels by axle, as disclosed 100% low-floor light rail vehicle rigid wheel in the patent documentation that Application No. 201310265642.X publication date is on November 6th, 2013 to single motor coaxle two-wheel drive mechanism, this drive mechanism is by framework, take turns to and driving means composition, take turns and form by wheel and the rotary shaft being connected on the wheel of both sides, driving means drives rotary shaft to rotate, thus driven wheel is to rotation, the wheel of this structure and rotating shaft coaxle, when light rail car is along curve motion, the guidance capability of mechanism of independent wheel is poor, bogie turn to freedom not good enough, the noise run is bigger than normal.Similar structure is also disclosed that in the patent documentation that document number is US20100132586A1.
nullA kind of axletree for low clearance chassis rail vehicle is disclosed in the patent documentation that Application No. 200710007908.5 publication date is on August 8th, 2007、Suspension arrangement and rail vehicle，And specifically disclose this rail vehicle and include car body and bogie，Wherein bogie includes framework and is suspended on the wheel assembly at framework two ends，Described wheel assembly is mainly by axle box、Mechanism of independent wheel、Cross member forms，Axle box is connected architecturally by single stage suspension，Mechanism of independent wheel is installed in the axial direction，Cross member is connected between two axle boxes of left and right，Although this bogie have employed mechanism of independent wheel structure，And have employed cross member，But cross member vertical direction generally within short axle below，When light rail car is along curve motion，Axle bridge composition occurs angle to change with mechanism of independent wheel the most simultaneously，The guidance capability of mechanism of independent wheel is poor，Bogie turn to freedom not good enough，The noise run is bigger than normal.Similar structure is also disclosed that in the patent documentation that document number is EP2551166A1, US8381659B2, US20130333590A1, the basic structure of these bogies is to use Longitudinal data transmission, by connecting axle box generally within the cross member below mechanism of independent wheel, when light rail car is along curve motion, axle bridge composition occurs angle to change with mechanism of independent wheel the most simultaneously, the guidance capability of mechanism of independent wheel is poor, bogie turn to freedom not good enough, the noise of operation is bigger than normal.
The bogie of a kind of lateral transmission is disclosed in the patent documentation that Application No. 201320379293.X publication date is on January 1st, 2014, this bogie is mainly by framework, it is right to take turns, lateral mechanism and drive mechanism composition, it is right that wheel connects the wheel described in being formed by power transmission shaft, lateral mechanism includes power transmission shaft, drive mechanism drives the wheel of side to rotate, and drive the wheel of opposite side to rotate by lateral mechanism simultaneously, the wheel of this structure and rotating shaft coaxle, when light rail car is along curve motion, the guidance capability of mechanism of independent wheel is poor, bogie turn to freedom not good enough, the noise run is bigger than normal.And if rotary shaft is the most directly removed, the wheel of both sides will separate, and gear-box and axle box also can separate simultaneously, and bogie will be unable to work normally.
It addition, existing 100% low-floor train bogie also is provided with air spring, air spring be a kind of utilize air compression after the elastic force that produces and the form of springs made, be mainly used in locomotive shock mitigation system.At present the air chamber on engine truck is usually mounted directly architecturally so that locomotive relies primarily on air spring as shock mitigation system, and such shock mitigation system stability is inadequate；It addition, each air chamber is to be supplied by independent trachea, add the complexity of air chamber spring structure.
Further, after car body is installed on bogie, the height of car body is far longer than the height of bogie, and therefore, train, in running, the phenomenon of lateral deviation easily occurs so that the fluctuation of service of train.
