Description
Technical field
The utility model relates to a kind of railway goods train bogie, especially a kind of high speed railway roller bearing adapter stabilizer bar.
Background technology
Railway goods train bogie generally has three-major-items formula roller bearing adapter stabilizer bar and framework type roller bearing adapter stabilizer bar at present; Because little, the unsprung weight of three-major-items formula roller bearing adapter stabilizer bar diamond resistant rigidity is big and distinct disadvantage such as disc braking can not be installed; Its running velocity can not surpass 120km/h; The framework type roller bearing adapter stabilizer bar then has remarkable advantages such as diamond resistant rigidity is big, unsprung weight is little, and its overall dynamic performance obviously is superior to three-major-items formula roller bearing adapter stabilizer bar.And the framework type bogie truck is according to the difference of its configuration; The bogie truck that 120km/h and two speed class of 160km/h are generally arranged; Domestic commentaries on classics K3 type bogie truck belongs to the bogie truck of 120km/h speed class, and its characteristic feature is that suspension is one to be axle box suspension, and foundation brake adopts tread brake.Chinese patent ZL01275171.5 (publication number CN 2517641Y); ZL200620034959.8 (publication number CN 200945865Y); Disclosing these two kinds of bogie trucks of a kind of " high-speed freight car bogie " and " quick railway goods train bogie " respectively all adopts integral frame to add the structural pattern of bolster; One is that the metal liquid complex spring is adopted in the location, adopts disc brake.Chinese patent ZL200720063538.2 (publication number CN201068149Y) discloses a kind of " a kind of railway vehicle is used high-speed freight car bogie "; It adopts the H shape framework of being made up of bolster and bogie side frame with certain diamond resistant rigidity; One is to adopt the molten metal complex spring, and is that the axle box suspension forms swinging gear one.More than three kinds of railway goods train bogies one be the axle-box positioning device that pellet type is all adopted in the location; Journal box spring adopts the metal liquid complex spring; Adopt the plane cartridge to add the associating bearing mode of The Constant-Contact Resilient Side Bearings, foundation brake adopts disc brake, all adopts the shaketable structure; Do not establish secondary spring and shock absorber, its highest running speed all is 160km/h.
But pass through China Express Railway shipping development policies, the pattern and the course analysis of the demand in railway freight market and the shipping of foreign railway development high speed, it is imperative that China will start overall trip speed 200km/h high speed goods train from now on.And at present domestic now also the high-speed freight car bogie to 200km/h is studied, its gordian technique that adopts was not carried out system analysis, present design proposes under this background.
The principle of design of the high-speed freight car bogie of 200km/h is: (1) adopts two to be spring suspension system; (2) one is the technology that should adopt mature and reliable, makes wheel to the location more suitable vertical, horizontal locating stiffness arranged, and can satisfy vehicle linear running stability, has to make vehicle have good curving performance, reduces wheel-rail wear; (3) secondary suspension should have less lateral stiffness; Should be outside the requirement of satisfying vehicle high-speed cruising time stability and stationarity on straight line, stability against overturning in the time of satisfying vehicle simultaneously again and pass through the main track railway curve and the anti-Derailment Safety requirement during through the little curve of non-main track; (4) framework should be the integral type framework, improves the diamond resistant rigidity of bogie truck; (5) foundation brake rigging adopts disc brake, adopts the anti-skid device technology, improves the adhesion factor degree of utilization, shortens the car brakeing distance; (6) simple in structure, easy to maintenance, maintenance cost is low.
Chinese patent ZL01275171.5 (publication number CN 2517641Y); ZL200620034959.8 (publication number CN 200945865Y); Three kinds of railway goods train bogies of ZL200720063538.2 (publication number CN201068149Y), the axle box rubber liquid complex spring technology that single stage suspension adopts is owing to technical reason; Be difficult to mix more suitable vertical, horizontal locating stiffness value, so limited the further raising of its critical speed; Above-mentioned three kinds of bogie trucks all adopt the associating bearing mode of cartridge and side bearing, because its structural reason, and linear running stability and curving performance in the time of can't obtaining more suitable steering resistance square and come to guarantee high speed simultaneously; Three kinds of bogie trucks all do not have secondary suspension, and the running stability requirement of vehicle has limited the raising of its critical speed in the time of can't obtaining high speed.
