Description
Technical field
The utility model relates to the steering swivel system of tramway train, is specifically related to a kind of three axle power trucks based on 100% low floor tramway train.
Background technology
" low floor " is a nomenclature of light rail vehicle, refers to the light rail vehicle that vehicle floor distance orbital plane is less than 40 centimetres.The percentum of guest room area can be reached according to vehicle low floor region, low floor vehicle divides number of different types again, wherein the most outstanding feature of " 100% low floor " modern tram is that cost is low, energy-conserving and environment-protective, its track can directly be laid on existing road, vehicle is stopped on ground, modern tram operational system laid down cost is only 1/4 to 1/3 of subway, and the duration is short, pollutes few.The urban tram delivery system built by this vehicle, passenger capacity, ride comfort sense, stability all higher than city motor bus, and have both city sightseeing function, and similar to subway in its car, admission fee, but lower than subway, has wide market outlook.
Bogie truck is one of most important parts on guideway vehicle, its direct bearing body deadweight and load-carrying, guided vehicle orbiting, ensure that vehicle passes through curve smoothly, and there is the effect slowed down from bringing vibrations and impact during vehicle operating, therefore the design of bogie truck directly determines stability and the travelling comfort of vehicle.
The problems such as at present, domestic and international 100% low floor modern tram all adopts two-axle bogie, and under equal passenger capacity condition, two-axle bogie ubiquity axle carries greatly, adhesion is more weak, wheel track adhesive ability is not enough.
Utility model content
The utility model is intended providing a kind of power truck being applicable to 100% low floor modern tram, under equal loading condition, compares two-axle bogie, car load acceleration/accel is high, hill climbing ability is strong, adhesive ability is large, and effectively reduction axle carries.
For this reason, the technical scheme that the utility model adopts is: a kind of three axle power trucks based on 100% low floor tramway train, comprise rectangular frame, wheel is to device, single stage suspension, secondary suspension, vertical damper, lateral damper, describedly take turns device totally three covers, on rectangular frame, time interval is arranged, it is right that every wheel comprises wheel to device, axle box and axletree, the side, front and back of each axle box is provided with described single stage suspension, before being wherein positioned at, the axletree that the wheel of rear both sides is corresponding to device is Power Available Shaft, the wheel of setting placed in the middle is non-power driven ultrasonic axle to the axletree of device, the side of every root Power Available Shaft is equipped with Power Drive Unit, opposite side is provided with brake equipment and earth system, but not the both sides of Power Available Shaft are all provided with brake equipment, and the different curb girders that two Power Drive Units are arranged on rectangular frame form skew symmetry outward arranges, described secondary suspension totally four, in rectangular layout outside two curb girders of rectangular frame, described vertical damper totally four, be arranged in four angle position places of rectangular frame, described lateral damper totally two, skew symmetry is arranged in the rear and front end of rectangular frame, and staggers with described Power Drive Unit and arrange, and the front center of described rectangular frame is provided with drawing pull bar, above-mentioned each parts, except Power Drive Unit and lateral damper, all distribute according to rectangular frame central point.
Preferred as such scheme, described Power Drive Unit comprises drive motor and reductor, described drive motor transverse horizontal is arranged, reductor is vertically arranged and is hung at side rail outer, drive motor export through reductor slow down after again by elastic clutch by transmission of power to correspondence axletree.The layout of optimizing power actuating device, is conducive to increasing the transverse width of rectangular frame curb girder and the cross-tie width of secondary suspension, increases the stability of bogie truck and car load.
Further, described vertical damper, lateral damper all adopt hydraulic damper, described single stage suspension adopts rubber cone spring or chevron pointing spring structure, and secondary suspension adopts hourglass spring or helical steel springs structure, and described brake equipment adopts hydraulic pressure disc-shaped brake device.
In addition, described drive motor is connected with rectangular frame elasticity, avoids drive motor and rectangular frame are rigidly connected and produce resonance.
The beneficial effects of the utility model: adopt the mode that traditional wheelsets structure and diaxon drive simultaneously, and to be overlapped by two device by wheel on this basis and be increased to three covers, under equal loading condition, reduce and share every wheel and carry the axle on device; Add the area of contact of bogie truck and wheel track, therefore improve the adhesive ability of bogie truck; Under same tractive force, hill climbing ability and acceleration/accel significantly improve.
