Abstract
The utility model relates to an axle box suspension swing type bogie for railway vehicle, which comprises a wheel pair 1, an axle box 2, an axle box elastic component 3, side frames 4, a positioning ball block 5, a shaking seat 6 and a bolster 7. The bolster 7 is pressed on the positioning ball block 5 on a lower wing plate of the middle section of the left and right side frames through the shaking seat 5 at the lower part of two ends, and the side frames 4 are also hinged and supported on the axle box elastic component 3 which is supported on the axle box 2. The special structure can make the left and right side frames 4 like two suspension rods, so as to drive the bolster 7 to swing transversely. The utility model uses a special swing mechanism hung on the spring, and ensures light quality under the bogie spring, small wheel-rail acting force, high critical speed, and superior cross performance for vehicle, meeting the need of developing railway vehicle with rapid speed.
Description
Technical field
The utility model relates to a kind of suspension swing type bogie of axle box for railway vehicle.Big parts that belong to railway vehicle.
Background technology
At present, railway vehicle (lorry) bogie truck generally is divided into the framework type bogie truck of axle box suspension and the three-major-items formula bogie truck of central mounting.The framework type bogie truck that its axle box hangs has that unsprung weight is light, and the wheel track action is firmly little, the advantage that critical speed is high, but the transverse elasticity of this bogie truck only provides by journal box spring, and very limited, lateral performance is not good enough during high-speed cruising; The three-major-items formula bogie truck of central mounting, its traditional diamond resistant rigidity is little, poor performance, can only satisfy the 80km/h operating needs, existing a kind of three-major-items central mounting swing type bogie, it is on traditional three-major-items basis, increase spring plank and shaken parts such as seat, constituted teeter mechanism, the transverse elasticity of bogie truck is provided by central spring and swinging gear combination, and the horizontal excitation and the car body that bogie truck can be subjected to are kept apart, and have improved the lateral direction of car performance greatly, but this bogie truck unsprung weight is big, the impact of wheel track when having strengthened high-speed cruising.
Summary of the invention
The utility model combines the advantage that above-mentioned axle box hangs framework type and two kinds of bogie trucks of central mounting oscillating type, provides a kind of unsprung weight light, and the wheel track action is firmly little, and transversal dynamic performance is superior, the suspension swing type bogie of axle box that critical speed is higher.Satisfy the needs of the quick lorry of railway.The technical solution of the utility model is: this suspension swing type bogie of axle box comprises that wheel is to, axle box, axle box elastic parts, bogie side frame bolster etc.It is characterized in that each hinged support of bogie side frame two ends on two axle box elastic partss, bogie side frame stage casing lower wing plate is provided with two place kick pieces.Below, bolster two ends is provided with the seat that shakes of band spill sphere, and the spill sphere that bolster shakes seat by two ends is pressed together on four place kick pieces of and arranged on left and right sides frame, but has been combined into the mechanism of teeter.In horizontal surface, bolster and side frames are subjected to the constraint of 4 place kick pieces, form the H shape framework with certain diamond resistant rigidity; At horizontal vertical plane surface, the and arranged on left and right sides frame quite hangs on two suspension rods on the axle box elastic parts, drives bolster and can do laterally swing synchronously.
In sum, a kind of suspension swing type bogie of axle box that the utility model provides is because it adopts the special swinging gear that hangs on the spring, guaranteed that this bogie truck unsprung weight is light, the critical speed height, the wheel track action is firmly little, the lateral direction of car superior performance satisfies the needs of the quick lorry of railway development.

Fig. 3 is a plan structure scheme drawing of the present utility model;
Fig. 4 is a teeter scheme drawing of the present utility model.
The specific embodiment
This suspension swing type bogie of axle box for railway vehicle, it comprise wheel to 1, axle box 2, axle box elastic parts 3 and swinging gear, swinging gear is to contain bogie side frame 4 and bolster 7, it is characterized in that: described axle box elastic parts 3 is arranged on the both wings of axle box 2, described swinging gear is arranged on the axle box elastic parts 3, is suspended swinging mechanism on the spring; Each hinged support of described bogie side frame 4 two ends is on two axle box elastic partss 3, bogie side frame 4 stage casing lower wing plates are provided with two place kick pieces 5, what bolster 7 two ends belows was provided with band spill sphere shakes seat 6, but promptly the spill sphere of bolster 7 by two ends swing seat 6 is pressed together on the mechanism that is combined into teeter on four place kick pieces of and arranged on left and right sides frame.
Referring to Fig. 1, Fig. 2, this bogie truck by standard wheels to 1, axle box 2, axle box elastic parts 3, bogie side frame 4, place kick piece 5 shakes seat 6 and composition such as bolster 7.
Axle box elastic parts 3 has certain vertical, horizontal, longitudinal elasticity rigidity, and is with bogie side frame 4 and is articulated and connected.Two place kick pieces 5 have been fixed on the lower wing plate in bogie side frame 4 stage casings.
Bottom, bolster 7 two ends is fixed with shakes seat 6, and the lower plane that shakes seat 6 has the ball impression of two spills, and bolster 7 is pressed together on four place kick pieces 5 of and arranged on left and right sides frame 4 by shaking seat 6.
Referring to Fig. 3, side frames 4 and bolster 7 constitute the H shape framework with certain diamond resistant rigidity in horizontal plane under the constraint of four place kick pieces 5, and this is that this bogie truck can have one of pacing factor of higher critical velocity.
Referring to Fig. 4, at Transverse plane, left and right bogie side frame 4 hinged supports are on the axle box elastic parts 3 that is installed on the axle box 2, and two bogie side frames 4 are equivalent to two suspension rods, by place kick piece 5 with shake seat 6, drive bolster 7 (comprising the car body that is bearing on the bolster 7) and do teeter.When horizontal excitation took place bogie truck, its car body line of centers can produce certain traversing amount e with wheel to line of centers.Horizontal excitation and car body that this swing function can be subjected to bogie truck are kept apart, improve the transversal dynamic performance of vehicle greatly, simultaneously because this swinging gear is to be bearing on the axle box elastic parts 3, thus this bogie truck to possess unsprung weight again simultaneously light, the wheel track action little advantage of exerting oneself.
Hence one can see that, and a kind of suspension swing type bogie of axle box that the utility model provides is because it adopts the special swinging gear that hangs on the spring, guaranteed that this bogie truck unsprung weight is light, the critical speed height, the wheel track action is firmly little, the lateral direction of car superior performance satisfies the needs of the quick lorry of railway development.
