It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
Example one

As shown in fig. 1, 2, 3 and 4, a single-axle bogie of an embodiment of the present application includes:
the wheel set comprises a single wheel set 1, wherein two wheels 11 of the wheel set are pressed on the same wheel shaft 12, and two ends of the wheel shaft 12 respectively protrude out of the two wheels 11;
two axle boxes 2 respectively sleeved at two ends of the wheel shaft 12 and positioned outside the wheels;
a suspension device fixed on the two axle boxes 2;
the truss comprises two parallel side beams 31, two parallel cross beams 33 and a middle longitudinal beam 32, wherein the side beams 31 and the cross beams 33 enclose a closed frame, the middle longitudinal beam 32 is arranged between the two side beams 31 in parallel, and two ends of the middle longitudinal beam 32 are respectively fixed with the two cross beams 33; the two side beams 31 are respectively located and connected above the two primary suspension devices;
wherein the center stringer 32 is used to reinforce the strength of the frame and provide a mounting interface.
In the single-axle bogie of the embodiment of the application, the number of wheel pairs is single, namely, the single-axle bogie. The two axle boxes are respectively sleeved at two ends of the wheel shaft and positioned outside the wheels, namely the axle boxes adopt an external axle box mode. The framework adopts the structure of Chinese character ri, and curb girder and crossbeam have enclosed into confined frame, have guaranteed framework structure's intensity, and simultaneously, middle longeron is parallel arrangement between two curb girders, and the both ends of middle longeron are fixed with the crossbeam respectively, have further strengthened the intensity of framework, and like this, the intensity of the framework as unipolar bogie installation basis is great. Because the primary suspension device is fixed on the two axle boxes, and the two side beams are respectively positioned and connected on the two primary suspension devices, the size of the framework in the length direction of the axle is larger, so that the installation space of the framework in the length direction of the axle is larger, enough installation space is provided for installing other devices of the single-axle bogie, and the size of the herringbone framework in the length direction perpendicular to the axle can be smaller. Compared with the traditional double-shaft bogie, the number of wheel sets is reduced, and the weight is reduced; the dimension of the herringbone framework in the length direction perpendicular to the wheel shaft is small, so that the structure of the single-shaft bogie in the rail direction is small, and meanwhile, the curve passing capacity is high. Therefore, the single-axle bogie structure and the self weight of the embodiment of the application are smaller, and the curve passing capacity is higher.
Specifically, the single-axle bogie can be suitable for railway road maintenance mechanical equipment, is particularly suitable for railway large-scale road maintenance mechanical equipment, and can also be suitable for other rail vehicles. The reason for using a herringbone frame for the frame is that the railway track maintenance machinery or other rail vehicles are mounted on a predetermined number of single axle bogies which carry the entire weight of the railway track maintenance machinery or other rail vehicles. Because the weight of railroad track maintenance machinery or other rail vehicles is significant, the weight carried by each single axle truck is also significant.
Specifically, the framework is an all-welded B-shaped framework. All parts of the whole single-axle bogie are arranged on the framework in a shape like the Chinese character 'ri', and the mounting positions of all parts are reasonably arranged according to the design requirements of railway road maintenance mechanical equipment or other whole railway vehicles, so that the single-axle bogie is convenient to assemble, replace and maintain.
It should be noted that, when the single-axle bogie is used for railway road maintenance mechanical equipment, when the railway road maintenance mechanical equipment is not in operation, the single-axle bogie is to bear the weight of the whole railway road maintenance mechanical equipment and the workers and materials carried by the railway road maintenance mechanical equipment, and when the railway road maintenance mechanical equipment is in operation, huge acting force can be generated on the single-axle bogie, so that higher requirements can be imposed on the overall strength of the single-axle bogie. Therefore, the single-axle bogie of the embodiment of the present application employs a japanese-character-shaped framework having higher strength.
In practice, as shown in fig. 2 and 3, the cross member 33 is a concave box structure with a low middle part and two high ends, the side member 31 is a flat plate-shaped box structure, and the top surfaces of the two ends of the cross member 33 are flush with the top surfaces of the side member 31;
wherein the middle of the cross beam 33 is used for providing a mounting interface.
The beam and the side beam of the box body structure have higher strength and smaller weight, so that the weight of the framework and the single-shaft bogie is smaller. In the side beams and the cross beams of the framework, only the middle part of the cross beam is in a downwards concave shape, and the middle part of the downwards concave cross beam is used for providing an installation interface, so that a lower installation interface is provided for the installation device of the framework, and the matching among all devices installed on the single-shaft bogie is realized. The side beam adopts a flat plate-shaped box body structure with the middle part and two flat ends, so that the action of force borne by the side beam can be better dispersed to the whole side beam.
In implementation, as shown in fig. 1, 2 and 3, two ends of the middle longitudinal beam 32 are respectively fixed at the top surface of the middle part of the two cross beams 33;
the center longitudinal member 32 is arched upward and the center longitudinal member 32 is higher than the side members 31 so that a mounting space is formed between the two side members 31 and the two cross members 33 under the center longitudinal member 32.
In this way, the center longitudinal beam is arched, so that the installation space between the two side beams and the two cross beams is larger under the center longitudinal beam, and space is provided for installing other devices of the single-shaft bogie.
In implementation, as shown in fig. 2, the fixed position of the middle longitudinal beam 32 and the fixed position of the cross beam 33 are the middle position of the cross beam, a transverse stopping mounting seat 41 is arranged in the middle of the middle longitudinal beam 32, and the transverse stopping mounting seat 41 and the wheel axle of the wheel pair are in the same vertical plane.
The lateral stops serve to limit lateral displacement of the vehicle body relative to the single-axle bogie, i.e. displacement along the length of the axle, as the vehicle body passes over the curved track. The transverse stop is located centrally of the entire frame, allowing balanced restriction in both transverse directions when passing through curved tracks. The transverse stopping position is arranged in the middle of the middle longitudinal beam and is in the same vertical plane with the wheel shaft, because the corresponding position of the frame can be provided with a limiting seat, and a certain gap is formed between the transverse stopping position and the limiting seat, the condition that the single-shaft bogie and the frame have too large rotating angle to influence the stability of the whole vehicle is avoided.
In practice, as shown in fig. 2, the truss further includes a center stringer stiffener 321;
the center longitudinal member reinforcing rib 321 is provided at an included angle between the center longitudinal member 32 and the cross member 33 toward the side member 31 to reinforce fixation between the center longitudinal member and the cross member.
The middle longitudinal beam reinforcing ribs are arranged at the included angles of the middle longitudinal beam and the cross beam towards the side beams, so that when the middle longitudinal beam is applied with acting force along the width direction of the middle longitudinal beam by the transverse stopping pieces, the middle longitudinal beam and the cross beam are fixed stably.
In implementation, as shown in fig. 1 and 2, the framework further includes a traction device mounting seat 42, where the traction device mounting seat 42 is disposed at the bottom of the middle portion of the cross beam 33, and is opposite to the position where the middle longitudinal beam and the cross beam are fixed;
fig. 7 is a schematic view of the hitch mount and drawbar arrangement of the single-axle bogie shown in fig. 1. As shown in fig. 7, the single-axle bogie further comprises a traction device 5, one end of the traction device 5 is hinged with the traction device mounting seat 42, and the other end of the traction device 5 is used for being hinged with a vehicle body.
Thus, the middle part of the cross beam is positioned at a lower position in the whole framework, is lower than the side beam and is also lower than the two ends of the cross beam; and the draw gear is connected in the bottom in the middle part of crossbeam, and draw gear has adopted the mode of low level installation promptly, is favorable to improving the adhesion utilization ratio of automobile body to realize the transmission of unipolar bogie and automobile body longitudinal force.
Specifically, the traction device is of a single-pull-rod structure and comprises a traction rod and two rubber joints connected to two ends of the traction rod; namely, the traction device adopts a low-position single pull rod structure;
one end of the traction rod is hinged with the traction device mounting seat through a rubber joint, and the other end of the traction rod is hinged with the vehicle body through a rubber joint.
The traction rod is connected with the single-shaft bogie and the vehicle body and used for transmitting traction force and braking force, and the rubber joints at the two ends are used for adapting to all-directional movement between the single-shaft bogie and the vehicle body, so that all-directional movement between the single-shaft bogie and the vehicle body can be effectively ensured, the single-shaft bogie can smoothly pass through a curve track with a small curve radius, and the traction rod is prevented from being interfered to hold the force. The traction device with the single-pull-rod structure has little influence on the vertical and transverse performances of the single-axle bogie, but can provide longitudinal rigidity, and effectively realizes the three-way decoupling of the secondary suspension device.
Fig. 5 is a schematic view showing the installation of the axlebox and the tapered rubber spring of the single-axle bogie shown in fig. 1. In practice, as shown in fig. 1, 4 and 5, the axle housing 2 is sleeved on the axle 12, and the primary suspension device comprises four conical rubber springs 61;
the bottom of each side beam is provided with two conical spring mounting seats 311, and the two conical spring mounting seats 311 are symmetrically arranged by taking a vertical plane where the wheel axle of the wheel pair is positioned as a symmetrical plane;
the bottom ends of the conical rubber springs 61 are fixed to two sides of the axle box, and the top ends of the conical rubber springs 61 are fixed to the conical spring mounting seats 311, so that the four conical rubber springs are symmetrically arranged relative to a vertical plane where the wheel axle of the wheel pair is located.
The four conical rubber springs are symmetrically arranged relative to a vertical plane where wheel shafts of the wheel pairs are located, the force applied to the wheel pairs is balanced, and balance of the framework can be well kept. A linkage suspension device adopts the toper rubber spring, like this, toper rubber spring and axle box matched with mode have realized the effort transmission of vertical, vertical and horizontal three direction between the framework of wheel pair and unipolar bogie, have played the effect of damping to the unipolar bogie, and the stationarity index is higher.
Specifically, the axle boxes may be provided with grounding devices and speed sensors as required.
In practice, as shown in fig. 1 and 3, the secondary suspension device further comprises four secondary steel springs 62;
two secondary spring mounting seats 312 are arranged at the top of each side beam, and the two secondary spring mounting seats 312 are symmetrically arranged by taking a vertical plane where the wheel axle of the wheel pair is positioned as a symmetrical plane;
the bottom ends of the secondary steel springs 62 are connected to the secondary spring mounting seats 312, so that the two secondary steel springs are symmetrically arranged relative to a vertical plane where the wheel shafts of the wheel pairs are located, and the top ends of the secondary steel springs 312 are used for being fixed with the vehicle body.
The four secondary steel springs are symmetrically arranged relative to a vertical plane where the wheel shafts of the wheel pairs are located, the action of force exerted by the vehicle body on the framework is balanced, and the balance of the framework can be well kept. The secondary steel spring provides rigidity in vertical, transverse and longitudinal directions and has the function of transmitting vertical force and transverse force.
Specifically, the conical rubber spring and the secondary steel spring which are arranged on the same side beam are positioned in the same vertical plane;
the distance from the secondary steel spring to the vertical plane where the wheel axle of the wheel pair is located is smaller than the distance from the conical rubber spring to the vertical plane where the wheel axle of the wheel pair is located.
The conical rubber springs and the secondary steel springs of the same side beam transmit vertical force on the same vertical plane, the stress of the side beam is relatively balanced, and balance of the framework can be well kept. The position of the rubber spring of the first series is determined by the position of the axle box and is positioned at the central plane position of the side beam of the framework, and the steel spring of the second series is also arranged at the central plane position of the side beam of the framework and is necessarily positioned on the same plane. And the distance between the relative positions of the rubber spring of the first series and the steel spring of the second series, the rubber spring of the first series is determined by the axle box, and the second series has no special requirement. It is only as close as possible, and is limited by the spatial position on the frame.
Specifically, the vertical stiffness of the conical rubber spring is greater than that of the secondary steel spring.
