Abstract

Disclosed is a positioned and split type secondary framework steering bogie, which relates to a steering bogie for railway wagons and belongs to the technical field of railway vehicles and machinery. The positioned and split type secondary framework steering bogie comprises two wheel pairs, lateral frames, swing bolsters and wheel set radial devices, wherein two ends of each wheel set are pressed with a rolling bearing device, the wheel set radial devices are arranged on four rolling bearing devices on the two wheel sets, the lateral frames are covered on the wheel set radial devices, and each wheel set radial device comprises two U-shaped secondary frameworks. The key points include that the U-shaped secondary frameworks are formed by positioning and assembling U-shaped secondary framework bodies and adapters. The utility model has the advantages that the U-shaped secondary frameworks only needs to change worn out adapters instead of the whole U-shaped secondary frameworks in station repair, thereby saving repair cost and bringing convenience for maintenance.

Description

Locate split type auxiliary frame work steering frame

Technical field

Locate split type auxiliary frame work steering frame, relate to the bogie truck that railway truck is used, belong to rolling stock and field of mechanical technique.

Background technology

For adapting to the fast development of China railways, new railway equipment continues to bring out.With the roller bearing adapter stabilizer bar is example, and the short several years develops into present commentaries on classics K5, changes K6 by changeing K1, commentaries on classics K2, commentaries on classics K4 etc.The common issue with that these bogie trucks exist is: unsprung weight is big, and wheel-rail force is big by curve the time, and wheel-rail wear is serious, improves the bogie truck movement vibration stability and improve to have implacable contradiction between the bogie truck curving performance all the time.Along with the heavy increase of bogie axle, the raising of speed, the wheel-rail wear problem is more serious.Wheel-rail wear aggravates, and shortens the service life of wheel, track greatly, causes the service expenditure of wheel, track sharply to increase.Change the appearance of K7 type bogie truck, reducing wheel-rail force and reducing on the wheel-rail wear and obtained good effect, but because the defective in the design, the secondary framework of its U-shaped is the secondary framework of integral type, inconvenience to some extent when the section maintenance of station, to the secondary framework palpus of the U-shaped that wears away limit integral replacing, thereby increased the cost of overhaul.

The utility model content

Problem to be solved in the utility model is exactly that a kind of split type auxiliary frame work steering frame that makes things convenient for the bogie truck maintenance, reduces the cost of overhaul is provided at the deficiency of integral type auxiliary frame work steering frame.

It comprises two-wheeled to, bogie side frame, bolster and wheel to device radially, wheel is pressed with rolling bearing system to two ends, two-wheeled is to installing wheel to device radially on four last rolling bearing systems, to suit bogie side frame on the device radially, wheel comprises two U-shapeds pair frameworks to device radially at wheel.Its gordian technique is that the secondary framework of U-shaped is assembled by secondary framework body of U-shaped and adapter location.

Compared with prior art, the utlity model has following beneficial effect:

1, detect by test and show: the utility model bogie truck is improving the bogie truck movement vibration stability and to improve between the bogie truck curving performance energy harmonious, can reduce wheel-rail force well and reduce wheel-rail wear, the bogie truck mechanical property is got a promotion, and this technical scheme is feasible.

2, the secondary framework of U-shaped need only be changed the adapter that wears away limit when the section maintenance of station, and need not change the secondary framework of whole U-shaped, saves the cost of overhaul 80%.

3, the secondary frame design novelty of this minute body structure, ingenious, simple in structure, easy to maintenance.

The specific embodiment

Referring to Fig. 1-Fig. 8, the utility model comprise two-wheeled to 1, bogie side frame 2, bolster 3 and wheel be to radially installing 4, wheel is pressed with rolling bearing system 5 to 1 two ends, two-wheeled is to installing wheel to radially installing 4 on four rolling bearing systems 5 on 1, to radially installing suit bogie side frame 2 on 4, wheel comprises the secondary framework 6 of two U-shapeds to radially installing 4 at wheel.Its gordian technique is that the secondary framework 6 of U-shaped is assembled by secondary framework body 7 of U-shaped and adapter 8 location.Specifically be to process locating surface A face, B face, C face respectively on the secondary framework body 7 of U-shaped, the A face is positioned on the U-shaped base plane of the secondary framework body 7 of U-shaped, has positioning boss 11 respectively in U-shaped base plane both sides, and two locating surfaces of positioning boss 11 are respectively B face and C face; On adapter 8, be processed with the locating surface A1 face, B1 face, the C1 face that cooperatively interact and locate with A face, B face, C face respectively, the A1 face is positioned at the end face of adapter, be provided with detent 12 in adapter both sides and positioning boss 11 correspondence positions, two locating surfaces of detent 12 are respectively B1 face and C1 face, are provided with voussoir draw-in groove 13 on adapter 8.Cooperate three locating surfaces of A1, B1, C1 of locating on the adapter 8 with three locating surfaces of A, B, C on the secondary framework body 7 of U-shaped during assembling, then voussoir 9 is put into voussoir draw-in groove secondary framework body 7 of 13 locking U-shapeds and adapter 8, and welding voussoir 9 and the secondary framework body 7 of U-shaped, make the secondary framework body 7 of U-shaped, adapter 8 as a whole, i.e. U-shaped pair framework 6 with 9 one-tenths of voussoirs.Adapter 8 is set on the rolling bearing system 5.According to circumstances, the quantity of voussoir 9 can be 1, also can be a plurality of.

When the section maintenance of station, the adapter 8 that wears away limit need only be changed, and need not change the secondary framework of whole U-shaped.

10 is weld seam among the figure.
