Description
Technical Field
The invention belongs to the field of non-power bogie devices of railway vehicles, and particularly relates to a non-power bogie with a temperature measurable axle box and a flexible interconnection framework.
Background
When the railway train bogie is designed, not only the structural strength and flexibility of a framework serving as a bearing main body, the action effect of various auxiliary damping components such as anti-snake dampers and the like, the installation mode of a braking mechanism and the like need to be comprehensively considered, but also various factors such as the suspension mode of a motor of the power bogie, the placement position of an axle box on a wheel shaft, the layout space of the motor and a gear box thereof, the structural form and the layout space of primary suspension and secondary suspension devices and the like need to be comprehensively designed according to the theoretical speed per hour, the bearing load, the minimum bend curvature, the road conditions such as wind, snow, flying stones and the like of trains according to different vehicle type requirements. Various design schemes developed around the core idea are improved and complicated day by day, so that iterative updating and continuous progress of the manufacturing level of the power bogie are promoted finally, framework schemes of different vehicle types are updated, and some new schemes of new forms even completely replace old ideas, so that the core improvement of the power bogie has obvious difference and innovation.
As shown in fig. 1 to 3, the frame of the bogie of the railway passenger car can be divided into a welded frame formed by butt welding a plurality of plate groups and a cast frame formed by integral casting, but the integral structures of the welded frame and the cast frame both belong to a frame which is formed by a cross beam body and two side beams and has a top view in a letter H shape, the geometric center of the frame is an integral cross beam body H or a cross beam body g in a shape like a Chinese character jing, the two types of cross beam bodies are both used for forming a short cross beam in the middle of a letter H stroke structure, and the two side beams are arranged at two ends of the cross beam body in a bilateral symmetry manner; the cross beam body is composed of two small cross beams perpendicular to the side beams. As shown in fig. 1 and 2, for a welded side sill formed by assembling and welding a plurality of plates to form a box-shaped structure, a welded side sill i is generally a bird wing-shaped structure with two upturned wings, and a welded axle seat i-2 is fixedly welded to a lower end surface of an inclined plane i-1 at a wing root part of each bird wing-shaped structure. And each welding piece side beam spring cap cylinder i-3 is fixedly connected to the tip end of one welding piece side beam i in a welding way. The side beam upper cover plate and the side beam lower cover plate of the welding part side beam i and the two welding part side beam side wall plates i-4 clamped between the side beam upper cover plate and the side beam lower cover plate are all special bird wing-shaped structures matched with the side wall plates i-4 of the welding part side beam, so that the clamping and positioning operation during the integral assembly welding of the welding part side beam i is relatively complex, a large number of positioning fixtures are needed to be used in the manufacturing process to ensure that the two welding part side beam side wall plates i-4 are respectively and vertically welded and fixedly connected with the welding part side beam lower cover plate according to the parallel postures, and the positioning of the plurality of side wall plate connecting rib plates and the welding part side beam spring cap barrel i-3 can be realized only by complex positioning tools which are additionally designed. For example, chinese patent publication No. CN110722319A discloses a welding and positioning tool for side beams of a railway carriage frame, and the disclosed complicated positioning tool structure is additionally designed to improve the assembly and positioning accuracy of components such as side beam spring cap cylinders i-3, reduce calibration and mapping work, and reduce labor intensity. Similarly, the process of positioning and welding the wheel axle seat i-2 at the lower end of the inclined plane of the wing root part of the side beam of the weldment can be smoothly implemented only by specially designing a group assembling and positioning tool for the normal assembling and welding of the side beam, wherein the group assembling and positioning tool is disclosed as CN108817797A, and the design and the manufacture of the positioning tool inevitably bring about great increase of the production cost. In the welding and cooling process of the welding side beam i, the welding side beam i is distorted and deformed in multiple directions and different dimensions due to the influence of stress during welding and cooling, so that the welding side beam i generates various asymmetric structural dimension deviations such as stretching, distortion, side inclination and the like, the welding quality can be reluctantly ensured only by additionally adding correction and adjustment operations, particularly, a welding side beam cross beam pipe through hole i-5 serving as a subsequent processing positioning reference can not be penetrated by a welding cross beam pipe g-1 or two welding cross beam pipes g-1 can not be kept parallel if the welding side beam cross beam pipe through hole is not coaxially aligned, calibrated and adjusted, so that the positioning reference and the subsequent machining precision of the whole welding framework are seriously influenced, even symmetrical parts such as an anti-snake-vibration absorber and the like can not fully play the damping function due to the failure of geometric symmetry, and further the vibration characteristic of the framework is influenced, impairing the overall service life of the bogie. However, the adjustment and repair work needs a large amount of surveying and mapping and repeated secondary processing work, and the workload is heavy and complicated, and the efficiency is low. For the cast side beam shown in fig. 3, the cast side beam j and the integral cross beam body h are integrally cast and molded by a casting mold, so that the processes of size measurement, clamping and positioning and the like in the manufacturing process of the welded side beam i are avoided, but compared with the welded side beam i, the flexibility of elastic deformation of the cast side beam is weakened due to the more rigid mechanical property of cast steel, so that the cast side beam needs to be matched with a more complex two-system damping system comprising a side rolling resistant torsion bar and a snake-shaped resistant damper. In addition, the existing cast side beam, the isosceles trapezoid large interface j-1 of the cast side beam j at the wingtip end, is specially designed for matching the axle box form of the axle box f stacked by multiple layers of rubber tiles e on the isosceles trapezoid, and is not suitable for the wheel set external axle box and the typical primary suspension structure corresponding to the axle box.
A primary suspension device of a railway car bogie is used to reduce the jounce vibration generated by wheel rails and axles, and as shown in fig. 1 and 2, a conventional typical primary suspension device is composed of a tray-type axle box a and a series of steel springs b mounted on the tray-type axle box a, and the upper ends of the series of steel springs b are used to support a circular cap tube at the end of a side sill of the bogie. Since the typical primary suspension device is mounted to the end of the axle d outside the wheel c, it is called a wheel-set external axle box. However, the axle box with the wheel set arranged externally greatly increases the total axial width of the wheel set, is easier to be impacted by flying sand and broken stone along the railway, increases the integral turning radius of the bogie, and is not beneficial to the improvement of the passing curvature of the minimum curve of the train. Another recent type of primary suspension device is shown in fig. 3, and it overcomes the old technical problem of the axle box with external wheel set by stacking a plurality of layers of rubber tiles e on both sides of the axle box f with isosceles trapezoid shape to form a built-in primary suspension structure of the axle box which can be arranged on the inner side of the wheel c. However, the isosceles trapezoid axle box built-in type primary suspension structure with the rubber piles on the two sides has the disadvantages of complex manufacturing process, complex dismounting and maintenance procedures and high manufacturing and maintenance cost.
A median vertical plane is a virtual geometric plane that symmetrically divides an object with a symmetrical structure into two parts that are mirror images of each other.
Disclosure of Invention
The technical problems to be solved by the invention are as follows:
1) in the manufacturing process of the existing welding type side beam with the bird wing-shaped curve structure, a large number of positioning clamps are needed to ensure that the side wall plates of the two welding side beams are respectively and vertically welded and fixedly connected with the lower cover plate of the welding side beam according to the parallel postures.
2) The positioning process of the plurality of side wall plate connecting rib plates of the welding type side beam and the spring cap barrel of the welding side beam can be realized only by additionally designed complex positioning tools; and it must be through the extra correction that increases and adjust and repair the operation and can correct the stretching, distortion, many asymmetric structural dimension deviations such as heeling of different yards and direction appearing in the welding cooling process, guarantee welding quality reluctantly; especially, the through hole of the beam tube of the side beam of the weldment serving as the positioning reference of subsequent processing must be coaxially aligned, calibrated and adjusted, otherwise, the beam tube of the weldment cannot penetrate into the through hole, or two beam tubes of the weldment cannot be kept parallel, so that the positioning reference and subsequent machining precision of the whole welding frame are seriously influenced, even symmetrical parts such as an anti-rolling torsion bar and an anti-snaking shock absorber cannot fully play the damping function because of the failure of geometric symmetry, the vibration characteristic of the frame is influenced, and the whole service life of the bogie is weakened.
3) Due to the design defects of the prior structure, the existing cast side beam for the high-speed running train needs to be matched with a more complex secondary damping system comprising an anti-rolling torsion bar and an anti-snake-shaped damper; in addition, the existing cast side beam, which has the large isosceles trapezoid interface at the wingtip end of the cast side beam, is specially designed for matching the axle box form of the axle box stacked by multiple layers of rubber tiles on the isosceles trapezoid, and is not suitable for the wheel-set external axle box and the typical primary suspension structure corresponding to the axle box.
4) In addition, the isosceles trapezoid axle box built-in type primary suspension structure with the rubber piles on the two sides has complex manufacturing process and complex disassembly, assembly and maintenance procedures, and causes high manufacturing and maintenance cost.

The design scheme ensures that the temperature measuring end of the temperature sensor can be inserted and positioned in the blind hole socket of the rubber ring through the sensor mounting hole and the socket of the shell in sequence, thereby getting rid of the separation effect of the damping rubber ring on the temperature of the axle box, enabling the semi-ring clamp type axle box hanging seat of the invention to become a brand-new clamp axle-hung wheel pair built-in type axle box capable of accurately measuring the temperature of the outer side wall of the axle box from the radial direction, the original structural design thoroughly breaks through the problem that the conventional axle box formed by stacking a plurality of layers of rubber tiles on an isosceles trapezoid can only be made into an open structural form, otherwise the temperature can not be accurately measured from the radial direction, and a typical series of suspension devices commonly constructed with a tray axle housing and a series of steel springs must rely on structural contraindications of weldment side beam spring cap cartridges, therefore, the design and manufacturing process of a complicated special positioning tool for the spring cap barrel of the side beam of the butt welding part is avoided. This design is in abandoning to pile up by multilayer rubber tile in isosceles trapezoid's axle box structure outside, still improves and has reduced the appearance and the size of the big interface of isosceles trapezoid of old foundry goods curb girder wingtip tip portion, and then promotes its mechanical structure intensity by a wide margin to make the installation and the temperature measurement of semi-ring clamp formula axle box hanging seat become possible. In addition, the structure form that the semi-ring clamp type axle box lifting seat is arranged inside the inner sides of the two wheels of the axle box is adopted to reduce the damage risk when the axle box is arranged externally, and on the premise of ensuring the installation position and the vibration reduction index of a primary suspension axle box device, the transverse width size and the turning radius of the whole bogie are effectively reduced, so that the curve passing capacity of the bogie is further improved. The compact type primary suspension structure based on the annular vibration reduction axle box benefits from the layout space saved by a new layout mode of a motor and a gear box, and the semi-annular shell of the compact type primary suspension structure is buckled with the semi-ring clamp type axle box suspension seat into a complete annular structure by adopting a split type clamp form connected by bolts, so that the compact type primary suspension structure is convenient to install, disassemble and maintain, and meanwhile, the adverse effect of welding deformation is avoided.
The bogie with the built-in axle box can ensure that two sleeper beam underlying secondary air springs, two sleeper beam underlying transverse shock absorbers and two vertical shock absorbers on an integrated vibration attenuation type swing bolster and a secondary suspension system are all directly connected to the lower part of the swing bolster on the transverse and longitudinal integrated flexible interconnection framework. The integrated secondary suspension device of the bogie is not directly connected to the lower part of a vehicle body from a framework like a secondary suspension device of a traditional bogie, so that the respective length requirements of the secondary damping buffer components are greatly reduced, the manufacturing cost is reduced, the structural strength is improved, the connecting processes of the traditional secondary transverse shock absorber, two air springs, two secondary vertical shock absorbers, an anti-rolling torsion bar and other components and the vehicle body are greatly reduced, the rapid falling of a carriage and the framework is realized, the occupied time of a crown block and a car lifting jack is reduced, the turnover efficiency of an assembly line is improved, and the integrated secondary sleeper beam system is convenient to independently replace and overhaul.

A ball socket is arranged in the joint ball bearing buckled ball socket retainer group, and a self-lubricating ring groove ball hinge is embedded in the ball socket of the buckled ball socket retainer group and forms a rotary friction pair with the ball socket; the buckled ball socket retainer group comprises a first hemispherical socket retainer and a second hemispherical socket retainer which are completely identical and are buckled and fixedly connected with each other, and a retainer circumferential ring groove is arranged on the outer diameter of a buckled circumferential boundary line of the first hemispherical socket retainer and the second hemispherical socket retainer; at least four retainer radial through holes pointing to the ball socket mass center are uniformly distributed on the bottom surface of the ring groove of the retainer circumferential ring groove according to the same circumferential angle. In addition, when the buckled ball socket retainer group is made of metal or ceramic materials with higher hardness and carbon rod materials which generate scale powder through friction are embedded in the equatorial plane annular groove and the two weft annular grooves which are distributed on the outer spherical surface of the self-lubricating ring groove ball hinge, the equatorial plane annular groove and the two weft annular grooves on the outer spherical surface of the self-lubricating ring groove ball hinge automatically rub the inner side wall of the ball socket of the buckled ball socket retainer group in the friction pair rotating process of the ball socket, so that the scale powder with the lubricating function is automatically generated through rotation and abrasion, thereby playing the role of self-lubricating of the ball socket. When lubricant containing 3% -5% of molybdenum disulfide is injected into the equatorial ring groove and the two weft ring grooves, the lubricating function can be achieved.
