Technical field

The present invention relates to a kind of rail vehicle truck, belong to rail vehicle truck field.

Background technology

Bogie truck realizes mainly plaing in operation in column at rail traffic vehicles and turns to (smoothly by each curve), carrying (realizing load-carrying target), traveling (realizing running velocity and riding quality), braking (realizing operational vehicle in column to stop in predetermined distance) effect.It is that rail traffic vehicles realizes heavy duty speed-raising and ensures key and the basis of vehicle operating quality.

Research is pointed out, the Hunting stability of diamond resistant rigidity to bogie truck of bogie truck has controlling effect, and diamond resistant rigidity is little, two-wheeled is shaken the head and reverse transverse motion in the same way to easy generation, bogie truck condenser stability is just poor, easily Snakes model occurs, and reduces vehicle stability.Therefore, the diamond resistant rigidity improving bogie truck is extremely important.

Current track load carrying vehicle bogie truck is mainly cast steel three-piece bogie, and in traditional cast steel three-piece bogie, its principal character is that side frame is connected by side frame central authorities square hole with bolster.Bolster can relatively left and right side frame do rise and fall, rolling pendulum motion.It is retrained by the spring at bolster two ends and oblique wedge vibration damper that side frame rotates relative to the level (shaking the head) of bolster, this the way of restraint is very not firm, and the magnitude of load that the prevention bolster that it provides bears with constraint and spring damper that diamonding occurs between side frame, the abrasion state of wedge are relevant with geometric configuration.When being in complete vehicle curb condition or wedge severe wear, this constraint is more open.When bogie truck runs, because front and back wheel is shaken the head and counter yaw moment serpentine locomotion in the same way to producing, will make the angular transposition in the same way in left and right side frame relative bolster occurred level plane, namely there is diamonding in bogie truck " framework ", affect operation stability, increase wheeling edge wearing.Meanwhile, when vehicle runs on curve, by the impact of side frame " rhombus dislocation ", the critical speed of curve passing through motion also can reduce, and aforementioned various adverse consequences also can be aggravated, and the maintenance cost of vehicle is also higher.
