Description

A high-speed railway freight car axle box built-in bogie

technical field

The utility model belongs to the technical field of rail transit. Specifically, it relates to an axle box built-in bogie applied to high-speed railway freight cars.

Background technique

Worldwide, there are mainly two types of truck bogies available. Countries in North America, Asia, South Africa and other regions mainly use three-piece bogies, while European countries mainly use integral frame bogies. In the development of the bogie, it is found that the requirement of improving the stability of the bogie's lateral motion and the requirement of improving the curve passing performance of the bogie are often contradictory. The use of radial bogies is an effective measure to solve the contradiction between stability and ability to pass through curves. Among them, the first successful and put into use is the Scheffel sub-frame self-steering bogie of the South African Railway. The bogie uses an arched beam to connect the left and right sides of each wheel set together to form a sub-frame; The radial mechanism is different from the American DR-1 type bogie. These three-piece bogies have good wheel load balancing ability and can better adapt to the unevenness of the line. However, their axle boxes are located on the outside of the wheel set, which is not conducive to reducing their own weight; and the rigidity of the shaking head is relatively high, which is not convenient for passing through small radius curves. The European LEILA bogie adopts an integral welded frame type, and its radial device is connected by a cross-shaped cross-link between the axle boxes. Compared with the three-piece bogie, the integral frame bogie has the advantage of not producing rhomboid deformation, but it also weakens the ability to adapt to road irregularities. The LEILA bogie is a bogie with built-in axle box, and its oscillating head stiffness is small, which is conducive to the passage of small-radius curves; at the same time, it also has a small dead weight. Compared with the Y25 bogie, its weight is reduced by about 1/5. The disadvantage of the inner axle box suspension bogie is that it is not easy to maintain and overhaul, so it has a higher requirement on the life of the axle box.

In China, the three-piece bogie had the Zhuan 8A type bogie in the early stage. This bogie had many problems such as low diamond resistance stiffness, large rhombus deformation, and small static deflection of pillow spring empty car. The Zhuan 8AG, Zhuan K1, Zhuan K2 and Zhuan K6 bogies developed later were all equipped with elastic cross braces on the basis of Zhuan 8A bogies to increase the shear stiffness of the bogies. and anti-diamond stiffness. The Zhuan K4 and Zhuan K5 bogies are swing bogies, which also increase the anti-diamond stiffness. The integral welded frame bogie is represented by the Zhuan K3 bogie. Although the rhombus has been completely eliminated, it also reduces the adaptability to the line, which is also a common problem of the integral welded frame bogie. Radial freight car bogies appeared relatively late in China, mainly Zhuan K7 type, and some bogies that have been developed but not put into use, and these bogies are all three-piece radial bogies. There is very little research on the axle box built-in bogie in China, which is blank in engineering application.

With the rapid development of China's national economy, the rapid increase of resource flow, and the rapid development of the transportation industry, the railway transportation, which is the king of land transportation, is also under increasing pressure. China also attaches great importance to railway transportation and supports some universities and enterprises to conduct related research. After 5 major speed increases, the development of railway passenger cars is relatively good, and the speed has increased significantly; while the development of freight trains is relatively slow, and the speed of traditional express freight trains is mostly only 160km/h. The mismatch between passenger transport and freight transport has become increasingly prominent, and as the basis for supporting national economic development, the development of freight transport has become more critical. The bogie directly affects the running performance of railway vehicles, and the benefits of high speed need not be repeated. Its development and research are particularly important.

The bogie is a key component of a railway vehicle. For a long time, due to the constraints of running stability, overturning safety and bearing maintenance and other factors, the railway vehicle mainly adopts the mode of external axle box suspension. With the continuous improvement of the running speed of railway vehicles, higher requirements are put forward for the light weight of the bogie and low wheel-rail force. The research shows that: compared with the bogie with external axle box suspension, the axle box built-in bogie can effectively reduce the weight of the wheel set and frame, which shows its excellent dynamic characteristics such as light weight and excellent curve passing performance. However, due to the inherent defect of the short span of the axlebox, the running speed of the existing fast axlebox built-in truck bogie LEILA is only 120km/h, which cannot meet the actual needs of cargo transportation.

(11) As shown in Figures 1 and 7, the secondary vertical stop: the frame side frame is provided with a secondary vertical stop, and the vertical stop is arranged on the side frame next to the secondary rubber pile. When the vehicle passes through a curve, limit the maximum roll of the vehicle body.

(12) As shown in Figure 13, the anti-roll torsion bar device: the anti-roll torsion bar device consists of a torsion bar, a torsion bar arm and a connecting rod. The torsion bar passes through the hollow small beam and is installed on the anti-roll torsion bar seat in the small beam of the frame, and the two ends of the torsion bar are located on both sides of the side frame of the frame; the two ends of the torsion bar are connected with the torsion bar arm, and the torsion bar arm It is arranged longitudinally along the bogie; the end of the torsion bar arm is connected with a connecting rod for connecting with the car body, and the connecting rod is vertically arranged along the bogie.

When the vehicle passes through the curve, limit the maximum lateral displacement of the vehicle body.

First of all, the first series of the bogie adopts the axle box pivot arm positioning and wheel set cross support mode, which reduces the longitudinal stiffness of the first suspension positioning and effectively improves the vehicle's ability to pass through curves. At the same time, the bogie adopts an H-shaped integral welded frame, the axle box positioning method adopts the high-speed rotating arm positioning method, and the anti-snake shock absorber and the secondary transverse shock absorber are used to effectively improve the serpentine movement of the vehicle. The smoothness and smoothness of motion, thereby increasing the critical speed of vehicle operation to achieve a higher operating speed.

It belongs to the category of high-speed truck bogies and has obvious advantages in transporting some high value-added products.

Secondly, the bogie is equipped with an anti-roll torsion bar device. Traditional trucks with external axle boxes basically do not have the problem of poor overturning performance. After switching to bogies with built-in axle boxes, due to the shortened span of the axle boxes, the anti-overturning ability of the axle boxes to the bogie frame and the car body is significantly reduced, and even some It may exceed the national GB5599-85 standard on the overturning requirements of rail vehicles, and the existing truck bogies do not use anti-rolling torsion bar devices to improve the anti-overturning performance of the vehicle. The anti-rolling torsion bar device of the traditional truck of the bogie is used to improve the anti-overturning ability of the vehicle. The anti-rolling torsion bar is set through the small beam of the frame, which solves the problem of insufficient anti-rolling ability of the secondary suspension and makes up for it. The problem of poor overturning performance of the truck bogie suspended from the inner axle box is solved. This scheme is also designed with secondary vertical stoppers, traction rods, and wheel set cross support devices, which can significantly improve the curve passing performance of trucks, especially the anti-rolling torsion bar and secondary vertical stoppers, which make up for the axle The box built-in bogie has the disadvantage of low anti-rolling ability.

Thirdly, the bogie is based on the built-in axle box. Since the vehicle is designed for high speed and low axle load, the hollow axle axle is used to further reduce the dead weight, while the wheelbase is greatly shortened and the traction rod with simple structure is used. With lower self-weight, it realizes light weight and low wheel-rail force. Compared with the traditional external axle box truck bogie, the axle box built-in freight car bogie greatly reduces the layout space of all bogie components, making the structure very compact. The wheelbase reduces the wheel set and frame size, reduces the overall weight of the entire bogie, effectively reduces the unsprung mass, and the axle length can be shortened by nearly 500mm. The bogie also adopts hollow axle technology. The overall mass of the bogie is reduced by 1/5-1/4 compared with the traditional outer axle box bogie. Under the same axle load, the load is 5-6t more than the traditional outer axle box bogie, which reduces the transportation cost and obtains more good economy. With the reduction of mass, the force between the wheel and rail is reduced, which improves the dynamic performance of the vehicle, reduces the wear between the wheel and rail, reduces the running noise and environmental pollution, increases the service life of the wheel set and railway rail, and reduces maintenance. cost.

Finally, the bogie uses the axle box built-in scheme to obtain the same lateral stability index as the traditional truck, mainly by increasing the longitudinal stiffness of the first series, but increasing the longitudinal stiffness of the first series will lead to poor curve passing performance. The scheme adopts the wheel set cross support device, which effectively improves the vehicle's ability to pass through curves and enhances the lateral stability at the same time. Due to the adoption of the built-in design of the axle box, it is more conducive to the placement of the wheel set cross support device in this scheme, effectively reducing the longitudinal stiffness of the suspension, which is conducive to the stability of the vehicle running, and at the same time taking into account the curve of the vehicle Passability.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
