Abstract
This utility model relates to a damping device hung on the axle box of a railway freight car bogie, which comprises an open type adapter, an enclosed type axle box positioning mechanism composed of a double head connecting rod and a long screw, and two rubber hydraulic springs, wherein, an elastic bushing is also installed in the opening on the outer side of the open type adapter to ensure the open type adapter to have elastic positioning rigidity in the horizontal direction. The damping device hung on the axle box of the railway freight car bogie can securely pass through curves, side tracks and hump vertical curves, and can also smoothly move on straight lines, the damping device has the advantages that the manufacture is convenient, and the overhaul is easy, and the damping device can meet the requirement of the heavy load and the speed acceleration improvement of the railway train.
Description
Technical field
The utility model relates to a kind of novel axle box suspended shock damper of railway goods train bogie.
Background technology
Railway goods train bogie mainly by wheel to, bogie side frame, bolster, compositions such as shock attenuation unit, adapter, wherein adapter is the lower openings type, the direct connection wheel to bogie side frame.Traditional common diamond resistant rigidity of this bogie truck is little, poor performance, and running velocity is not high, and the bogie truck unsprung weight is big, and the abrasion between wheel track are serious, and the maintenance cost of vehicle is higher.
Summary of the invention
The purpose of this utility model is exactly the novel axle box suspended shock damper that a kind of railway goods train bogie will be provided, and this shock absorption device has been arranged, and just can better solve the two large problems that conventional bogie exists.
The technical solution of the utility model is---a kind of novel axle box suspended shock damper of railway goods train bogie, it comprises the open type adapter, it is characterized in that: it also comprises double end pipe link and nut, they constitute closed axle box detent mechanism with open type adapter and long bolt, and double end pipe link wherein is the steel pipe that external diameter is equal to or less than bearing length 1/3rd; In the hole in the described open type adapter outside, also be pressed with resilient bushing, carry out elasticity with adapter end, bolster end respectively by longitudinal tie and be connected; Described each novel axle box suspended shock damper also comprises two rubber liquid springs.
The beneficial effects of the utility model are: adopt railway goods train bogie of the present utility model, its longitudinal register rigidity obviously increases, guarantee bolster and the wheel between normotopia, except that preventing that side frames from taking place " rhombus dislocation ", can also make and operate steadily, improve the vertical and horizontal tractive performance and the curving performance of vehicle, improve the hunting critical speed of bogie truck; In addition, it is right with wheel to connect bogie side frame with the utility model, has not only realized taking turns right vertical, horizontal location, and has reduced unsprung weight, has alleviated the abrasion between the wheel track.
Description of drawings
Fig. 1 is the structural representation of closed axle box detent mechanism in the utility model.
Fig. 2 is closed axle box detent mechanism and longitudinal tie annexation figure.
Fig. 3 is a structural representation of the present utility model
Among the figure, 1---the open type adapter, 2---the double end pipe link, 3---nut,, 4---longitudinal tie, 5---resilient bushing, 6---locating bush, 7---screw rod, nut, packing ring, 8---the rubber liquid spring, 9---a screw rod, 10---black nut.
The specific embodiment
As shown in Figure 1, closed axle box detent mechanism is made up of open type adapter 1, double end pipe link 2, nut 3 and long bolt, wherein double end pipe link 2 is diameter steel pipes less than bearing length 1/3, and this structure has advantages such as reliable, convenient manufacturing of structural strength and maintenance.
As shown in Figure 2, longitudinal tie 4 is connected with the outer end of above-mentioned closed axle box detent mechanism by resilient bushing 5, and the participation bonded assembly also has locating bush 6 and screw rod, nut, packing ring 7, and the other end of longitudinal tie 4 is connected with bolster end elasticity.Realize the elasticity location that wheel is right by elasticity of compression lining 4 during operation.
As shown in Figure 3, be provided with rubber liquid spring 8 between bogie side frame and closed axle box detent mechanism, be connected by two-thread screw 9 between rubber liquid spring 8 and the closed axle box detent mechanism, two-thread screw 9 lower ends have black nut 10 and packing ring fastening.Rubber liquid spring 8 is installed guide hole by the bogie side frame upper spring vertical, horizontal rigidity fixedly is provided.The utility model can be suspended on sprung weight on the wheel set bearing, reduces the purpose that wears away between wheel and rail thereby reach.Adopt bogie truck of the present utility model can pass through curve, track switch, hump vertical curve safely, also can be on straight line smooth running, have easily manufactured, maintenance and be easy to characteristics, can satisfy the requirement of railway truck heavy duty and speed-raising development.
