Description

Transverse and longitudinal integrated power bogie with temperature-measurable axle box

Technical Field

The invention belongs to the field of power bogie devices of railway vehicles, and particularly relates to a transverse and longitudinal integrated power bogie with a temperature-measurable axle box.

Background

When the railway train bogie is designed, not only the structural strength of a framework serving as a bearing main body, the action effect of various auxiliary damping components such as anti-snaking dampers and the like, the installation mode of a braking mechanism and other comprehensive factors 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 an axle, 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 curve 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.

Railway vehicle bogies with traction motors, commonly referred to as power bogies, typically employ a two-stage suspension system.

As shown in fig. 1 and 2, a conventional typical primary suspension device is composed of a tray-type axlebox a and a series of steel springs b mounted on the tray-type axlebox a, and the upper ends of the steel springs b are used for supporting round cap cylinders at the ends of side sills of a 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.

On the other hand, the whole cross beam body h or the cross beam body g of the existing power bogie is generally provided with a motor hanging seat t and a gear box hanging seat u which are respectively used for fixedly connecting a traction motor r and a gear box s, and the reverse torques of the two motors are counteracted by adopting a double-motor installation mode that the front traction motor r and the rear traction motor r are rotationally and symmetrically arranged by the geometrical center of the whole cross beam body h or the cross beam body g, so that the whole mechanical stability and the vibration balance characteristic of the power bogie are optimized. However, the installation mode depends on the integral cross beam body g or the cross beam body h in a shape like a Chinese character jing and is completely and rigidly connected with the motor hanging seat t and the gear box hanging seat u, and the layout position and the welding manufacturing process of the motor hanging seat t and the gear box hanging seat u not only provide higher requirements for the structural strength and the symmetry precision of the cross beam body, but also occupy most of the space on the inner side of the conventional framework, so that the inner side of the conventional bogie lacks enough axle box layout space, a typical primary suspension device can only be arranged at two end parts of an axle, the risk of damaging an axle box is increased, the integral structural size and the turning radius of the bogie are increased, the improvement of the minimum curve passing capacity is not facilitated, and the lifting lugs of the shell of the traction motor r are non-detachable rigid structures, so that the lifting lugs of the shell of the traction motor r interfere with the framework and the gear box structure to block each other, the traction motor r cannot be directly detached from the lower part of the vehicle body in the overhaul trench, and the car lifting jack is required to be used for separating the carriage above the framework from the framework, so that the traction motor r can be detached from the upper part of the framework, and the difficulty in motor maintenance and replacement is greatly increased. Meanwhile, the motor hanging seat t and the gearbox hanging seat u which are rigidly connected also cause that the traction motor r and the gearbox s lack an enough vibration damping protection system, so that the installation of auxiliary structures such as an anti-snake-shaped vibration damper, an anti-side-rolling torsion bar n and the like becomes indispensable necessary supplement.

In addition, different train design hourly speed requirements or different side beam structural forms can also have great influence on the layout space and structural form of the primary suspension device, the secondary suspension device, the motor and the gear box, which often results in that the layout scheme of the old primary suspension device or secondary suspension device cannot meet the requirements of installation position and vibration reduction index, and the old reference scheme must be overturned to make design improvement of a brand new concept.

As shown in figures 4 to 6, the big gear s-2 installed inside the housing s-1 of the existing buckling and splicing type gear box is directly pressed with the bearing outer ring s-3-2 on the big gear bearing s-3 to form a coaxially fixed interference fit, the gear box installation shaft section d-1 on the axle d is directly pressed with the big gear bearing inner ring s-3-1 on the big gear bearing s-3 to form a coaxially fixed interference fit, the coaxially fixed form of the interference fit causes the gear box installation shaft section d-1, the gear box bearing s-3 and the big gear s-2 to be an inseparable whole, and because the structural strength of the housing s-1 of the buckling and splicing type gear box is low, the housing can not be directly used as the origin of a releasing baffle plate on a wheel shaft releasing and releasing force machine, and, the bearing inner ring of the existing large gear bearing s-3 is too narrow, so that even if a withdrawal baffle on a wheel shaft withdrawal pressure machine is refitted into a multi-jaw chuck form, the bearing is inserted into the gear box from an axle through hole on the axial side wall of the gear box, and the radial withdrawal stopping acting force cannot be reliably implemented on the inner ring s-3-1 of the large gear bearing because of lack of enough radial acting points, so that the axle withdrawal cannot be directly implemented, when the axle d or the big gear s-2 is repaired subsequently, the original splicing and buckling state of the casing s-1 of the gear box which is buckled and spliced is firstly released, and the axle d, the gearwheel s-2 and the gearwheel bearing s-3 which are coaxially and fixedly connected with the axle d are integrally dismounted from the framework and then transferred to an axle dismounting pressure machine to finish dismounting and replacing operations. The method is complicated in process, time-consuming and labor-consuming, and cannot be used for conveniently and rapidly detaching and replacing the axle d on the premise of not detaching the gearwheel s-2 from the buckled and spliced type gear box shell s-1, or the axle d cannot be detached independently and the gearwheel s-2 in the gear box shell s-1 can be directly overhauled, lubricated and maintained at a hole left after the axle d is removed on the premise of keeping the buckled state of the buckled and spliced type gear box shell s-1. And axle box mounting journal sections d-2 at two ends of the axle d are coaxially and fixedly connected with bearings B-2 of wheels.

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.

5) On the other hand, rely on whole crossbeam body or well style of calligraphy crossbeam body and completely with motor hanger bracket and gear box hanger bracket rigid connection's motor mounting means, the overall arrangement position and the welding manufacturing process of its motor hanger bracket and gear box hanger bracket, not only all put forward higher requirement to the structural strength and the symmetry precision of crossbeam body, but also occupied most space of conventional framework inboard, cause current bogie inboard to lack sufficient axle box overall arrangement space, cause typical primary suspension device to only can arrange at two tip of axletree, not only increased the impaired risk of axle box, also increased the holistic structural dimension of bogie simultaneously and radius of gyration, be unfavorable for the improvement of its minimum curve throughput.

6) Because the lug of traction motor shell is undetachable rigid structure, cause it to interfere each other with framework and gear box as the structure and block, cause traction motor can't directly remove alone from automobile body below via in overhauing the trench, and must use car lifting jack, with the carriage and the framework separation of framework top, could realize moving back traction motor from the framework top and unload, greatly increased the degree of difficulty that motor maintenance was changed.

7) The large gear installed in the buckled and spliced gear box shell forms an interference fit through the large gear bearing and the gear box installation shaft section of an axle to form a coaxially fixedly connected form, so that the gear box installation shaft section, the gear box bearing and the large gear form an inseparable whole, and the buckled and spliced gear box shell cannot be directly used as an acting point of a withdrawing baffle on an axle withdrawing pressure machine due to low structural strength, and moreover, the inner ring of the bearing of the existing large gear bearing is too narrow, so that even if the withdrawing baffle on the axle withdrawing pressure machine is modified into a multi-claw chuck form and inserted into the gear box from an axle through hole on the axial side wall of the gear box, the inner ring of the large gear bearing cannot be reliably subjected to radial withdrawing blocking acting force due to lack of sufficient radial acting points, and the axle withdrawing cannot be directly implemented, when the factors cause follow-up maintenance of the axle or the gearwheel, the axle cannot be conveniently and rapidly detached and replaced independently on the premise that the gearwheel is not detached from the shell of the lock splicing type gearbox, and the axle cannot be pulled out independently on the premise that the lock state of the shell of the lock splicing type gearbox is kept, and the gearwheel in the shell of the gearbox can be directly maintained, lubricated and maintained through holes left after the axle is detached.

In the design scheme, the main structure of the metro bogie of the invention avoids the parallel positioning and the assembly welding process of the traditional welding side beam wall plate by the transverse and longitudinal integrated frame integrally formed by casting technology, and the main structure of the two transverse and longitudinal integrated frames symmetrically arranged in a circumferential rotational symmetric layout mode changes the traditional H-shaped frame form of the traditional bogie which vertically connects the two side beams by two thick cross beams, so that the two transverse and longitudinal integrated frames of the invention do not need to additionally correct the structural dimension deviation of stretching, twisting, tilting and the like in different dimensions and directions in the welding and cooling process aiming at the correction and adjustment operation of the cross beam pipe of the old welding part when being assembled and connected with each other, thereby overcoming the inherent process problem that the side beam group must be corrected by heavy and complex surveying and mapping operation and adjustment operation during the welding process, the assembly operation flow between the side beam and the cross beam is simplified and optimized to a low degree, the combined installation process of the two transverse and longitudinal integrated frameworks is convenient and fast, time and labor are saved, the precision is high, the effect is good, the mechanical strength of the main body structure of each transverse and longitudinal integrated framework can be obviously enhanced, the manufacturing cost is greatly saved, and the production efficiency is improved.

The semi-ring clamp type axle box hanging seat is arranged at the bottom of the far end of the cantilever section of each bird wing-shaped side beam, and a sensor mounting hole is formed in the upper end face of each semi-ring clamp type axle box hanging seat; the two annular damping axle boxes are arranged on the inner sides of the wheels and coaxially fixedly connected to the two ends of the axle, damping rubber rings arranged inside the annular damping axle boxes are coaxially fixedly connected with the outer rings of the axle bearings, the inner rings of the axle bearings are coaxially and pressure-mounted and fixedly connected to the two ends of the axle, rubber ring blind hole sockets for positioning temperature sensors are arranged on the upper portions of the damping rubber rings of the annular damping axle boxes, shell sockets serving as positioning temperature sensor butt-joint seats are arranged on the upper portions of the axle box positioning and temperature measuring heat conducting sheaths, and the positions of the two sockets of the axle box positioning and temperature measuring heat conducting sheaths. 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 complicated special positioning tool for the spring cap barrel of the side beam of the butt welding part is not designed and manufactured, and the complicated using process is avoided. This design is in abandoning to pile up by multilayer rubber tile at isosceles trapezoid's axle box structure scheme outside, still improves and dwindles the appearance and the size of the big interface of isosceles trapezoid of old foundry goods curb girder wingtip tip portion remarkably, 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. In addition, the hoop axle-hung wheel pair built-in axle box taking the annular vibration reduction axle box as the core can also fully release vertical and longitudinal torques generated by the side rolling motion of the vehicle body, effectively eliminate all the vibrations such as transverse, longitudinal, vertical and snake-like torsional pendulum, side rolling and the like generated by the motor and the gear box, and further achieve a more ideal vibration balance effect, thereby reducing the vibration influence degree of the bogie on the vehicle body to the minimum, enhancing the balance stability and the comfort of the vehicle body, effectively reducing the fatigue loss of the whole structure, and greatly prolonging the whole service life of the bogie and the vehicle body.

The non-power bogie of the invention can ensure that two sleeper beam underlying secondary air springs, sleeper beam underlying transverse shock absorbers and two vertical shock absorbers on an integrated vibration damping 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 interconnection framework of the invention.
