Detailed implementation manners

[0038] The following further describes in detail the implementation manners of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0039] As Figure 1 shown, an embodiment of the present utility model provides a transverse stop seat 200, which can be installed in pairs on the frame of the bogie, specifically connected to the cross beam 100 of the frame, that is, connected at the connection between the cross beam 100 and the longitudinal beam. Since the connection between the cross beam 100 and the longitudinal beam in the frame has a relatively large connection strength so that the cross beam 100 can transmit a sufficiently large lateral load, the transverse stop seat 200 connected at the connection between the cross beam 100 and the longitudinal beam can have a stronger lateral stop effect than the traditional transverse stop seat 200.

[0040] The following Figures 1 to 4 elaborates in detail the specific structure of the transverse stop seat 200 in the embodiment of the present utility model and its specific installation position on the frame.

[0041] As Figure 1 shown, the bogie described in the embodiment of the present utility model includes a frame. The frame includes a cross beam 100 and a pair of longitudinal beams. A pair of transverse stop seats 200 as described in the embodiment of the present utility model are installed on the cross beam 100 of the frame.

[0042] As Figure 2As shown in the figure, the lateral stop seat 200 in the embodiment of the present utility model includes a connecting portion 210 and a stop portion 220. One end of the connecting portion 210 is adapted to be connected to the cross beam 100 of the composite material frame; the stop portion 220 is connected to the other end of the connecting portion 210, and the stop portion 220 is adapted to face the position of the center pin. The stop portion 220 can bear the lateral load received by the bogie and play a lateral stop role on the center pin. The connecting portion 210 plays a role in load transfer and impact resistance, and the lateral length of the connecting portion 210 can define the installation position of the center pin, thereby realizing the lateral positioning function for the entire bogie frame. The connecting portion 210 includes a connecting channel 213, and the connecting channel 213 extends along the lateral direction of the frame and forms a plurality of cross-sections, and the area of each cross-section gradually decreases from the outside to the inside along the lateral direction of the frame. By setting the channel structure with a gradually changing cross-section, the lateral stop strength of the lateral stop seat 200 can be improved, and the connection end between the channel structure and the cross beam 100 is the largest cross-section, thereby expanding the connection area between the lateral stop seat 200 and the cross beam 100 and improving the connection strength. Compared with the traditional lateral stop seat 200, the lateral stop seat 200 of the present utility model has the advantages of simple structure, convenient assembly, high self-strength and high connection strength with the cross beam 100.

[0043] It should be noted that the directions described in the present utility model are all based on the running direction of the rail vehicle. The "front" and "rear" described in the present utility model refer to the front and rear directions of the vehicle running, that is, the "longitudinal direction" described in the present utility model, that is, the length direction of the vehicle or the bogie. The "lateral direction" described in the present utility model refers to the width direction of the vehicle or the bogie. The "vertical direction" described in the present utility model refers to the height direction of the vehicle or the bogie. The "inside" described in the present utility model refers to the direction inside the vehicle, that is, the direction of the longitudinal center line of the bogie; similarly, the "outside" described in the present utility model refers to the direction outside the vehicle, that is, the direction away from the longitudinal center line of the bogie. The "flat setting" described in the present utility model means setting along the upper surface of the cross beam 100 or a surface parallel to the upper surface. In the state of the vehicle running smoothly, the "flat setting" can be equivalent to the horizontal setting.

[0044] It can be understood that the connecting portion 210 of the above-mentioned lateral stop seat 200 is integrally in a trumpet-shaped structure from the outside to the inside of the bogie in the lateral direction. Or as Figure 1 shown, the connecting channel 213 of the connecting portion 210 includes a top plate, a bottom plate and a pair of side plates connected between the top plate and the bottom plate. The top plate and the bottom plate are both flatly arranged, and the pair of side plates are respectively connected between the top plate and the bottom plate and are longitudinally connected to the longitudinal two sides of the top plate and the bottom plate along the longitudinal direction of the bogie, that is, the connecting channel 213 is formed by enclosing a channel structure by the top plate, the bottom plate and a pair of side plates.

[0045] It is understandable that a rectangular coordinate system is established with the bogie during vehicle parking or driving, with the center pin position as the origin; the vehicle width direction is the transverse direction, i.e., the X-axis; the vehicle length direction is the longitudinal direction, i.e., the Y-axis; and the vehicle height direction is the vertical direction, i.e., the Z-axis. The cross-section of the connecting portion 210 described in the present invention refers to the cross-section obtained by cutting the connecting portion 210 of the transverse stop seat 200 parallel to the YOZ plane, and the connecting channel 213 of the connecting portion 210 extends along the X-axis direction to obtain a number of the above cross-sections.

[0046] It is understandable that each of the above cross-sections is preferably square-round, and can also be circular, elliptical or polygonal in structure, as shown in Figure 3 shown. The cross-section forming a square-round shape means that the corner position of the connecting channel 213 is a rounded corner structure. In fact, chamfering at the turning position of the connecting channel 213 can facilitate processing and installation, and can effectively remove machining residual burrs, ensure the installation accuracy and performance of the connecting portion 210, and improve the stress concentration situation of the connecting portion 210.

[0047] In some embodiments, it is preferred that the connecting portion 210 of the transverse stop seat 200 is a carbon fiber connecting portion 210, and the structure of the connecting channel 213 is constructed for the carbon fiber connecting portion 210, so that the weight of the transverse stop seat 200 can be reduced by using carbon fiber, and the self-structural strength of the transverse stop seat 200 can be ensured, and it can assist the cross beam 100 to bear the transverse load and certain impacts generated during vehicle driving. The stop portion 220 is preferably a metal stop portion 220, so as to ensure that the connecting portion 210 can be protected under the direct impact of the load, avoid damage to the carbon fiber connecting portion 210, and can also play a role in protecting and reinforcing the protruding end of the connecting portion 210.

[0048] It is understandable that carbon fiber refers to high-strength and high-modulus fibers with a carbon content of more than 90%. It has characteristics such as high temperature resistance, anti-friction, heat conduction and corrosion resistance. The main use of carbon fiber is as a reinforcing material to be compounded with resins, metals, ceramics and carbon to manufacture advanced composite materials. For example, carbon fiber reinforced epoxy resin composite material has the highest specific strength and specific modulus among existing engineering materials.

[0049] It is understandable that the transverse stop seat 200 provided in the embodiment of the present invention is preferably connected to a carbon fiber framework, that is, the cross beam 100 of the framework is a carbon fiber cross beam 100. In this way, the material of the connecting portion 210 is the same as that of the framework, which is more conducive to assembly and load transfer, can form a stronger transverse stop effect, and can meet the requirements of vehicle overall lightweight.

[0050] It is understandable that the metal stop 220 is preferably a cast steel stop 220. Cast steel is a kind of casting alloy, with iron and carbon as the main elements, and the carbon content is between 0 and 2%. Cast steel has the following advantages: low production cost, high strength, good toughness and strong plasticity. Therefore, the cast steel stop 220 can be used as the structure at the extended end in the lateral stop seat 200, which can greatly improve the self-strength of the lateral stop seat 200 and the lateral stop ability of the lateral stop seat 200 during vehicle operation.

[0051] In some embodiments, as Figure 2 shown, the connecting portion 210 includes a first plate body 211, a second plate body 212 and the connecting channel 213. The first plate body 211 is adapted to be connected to the side wall of the cross beam 100 of the frame, and the side wall of the cross beam 100 faces the center pin. The second plate body 212 is connected to the stop portion 220 through the connecting channel 213. That is, the first plate body 211 and the second plate body 212 as connecting plates are respectively added at both ends of the connecting channel 213, so that the connection between the connecting portion 210 and the side wall of the cross beam 100 and the connection and installation between the connecting portion 210 and the stop portion 220 are more convenient and the connection strength is higher. Preferably, a plurality of rivet holes are arranged at intervals around the first plate body 211, and the first plate body 211 can be directly fixed to the side wall of the cross beam 100 by using rivets. Preferably, through holes are provided on the second plate body 212 so that the stop portion 220 can be fixed to the second plate body 212 by screws or bolts.

[0052] In some embodiments, preferably, the maximum cross-section of the connecting channel 213 is connected to the first plate body 211 so as to increase the connection area between the connecting portion 210 and the side wall of the cross beam 100 and improve the connection strength between the connecting portion 210 and the cross beam 100. The minimum cross-section of the connecting channel 213 is connected to the second plate body 212, so as to facilitate the fixing and installation of the stop portion 220 more conveniently.

[0053] In some specific embodiments, the overall structure of the connecting channel 213 is sectioned along the XOY plane to form a structure with a trapezoidal outer contour. That is, the longitudinal sides of the connecting channel 213 are constructed as a pair of relatively inclined outer side wall surfaces, and the distance between the connection of the pair of outer side wall surfaces and the first plate body 211 is greater than the distance between the connection of the pair of outer side wall surfaces and the second plate body 212. The inclined outer side wall surfaces can enable the connecting portion 210 to transfer lateral loads while improving the resistance to lateral impacts and enhancing the self-structural strength of the lateral stop seat 200.

[0054] In some specific embodiments, as Figure 3As shown, it is preferable that reinforcing ribs 214 are constructed inside the connecting channel 213. The reinforcing ribs 214 divide the interior of the connecting channel 213 into a first cavity 2131 and a second cavity 2132 arranged in parallel, so as to avoid excessive hollow area in the connecting channel 213 resulting in insufficient pressure-bearing capacity between the top plate and the bottom plate, and improve the impact resistance. Preferably, the reinforcing ribs 214 include rib plates 2141. The rib plates 2141 are arranged vertically along the framework and are connected between the top plate and the bottom plate of the connecting channel 213 to play a vertical strengthening role inside the connecting channel 213.

[0055] In some specific embodiments, such as Figure 3 shown, the rib plate 2141 is a straight plate, that is, the rib plate 2141 is an overall plate-like structure. That is, as Figure 2 and Figure 3 shown, the rib plate 2141 divides the connecting channel 213 into a first cavity 2131 and a second cavity 2132. The first cavity 2131 and the second cavity 2132 respectively form two first open ends 215 arranged in parallel at the position of the first plate body 211, and the first cavity 2131 and the second cavity 2132 respectively form two second open ends 216 arranged in parallel at the position of the second plate body 212. Since the two side walls of the connecting channel 213 along the longitudinal direction of the vehicle body are respectively inclined between the first plate body 211 and the second plate body 212, the horizontal section of the connecting channel 213 forms a trapezoidal structure. Then the above two first open ends 215 are adjacent and the above two second open ends 216 are also adjacent. The two channels formed by the first cavity 2131 and the second cavity 2132 share the same rib plate 2141 as the adjacent side wall. This structural setting makes the structure of the connecting channel 213 the simplest. The plate-like rib plate 2141 completely bears the partition and vertical support functions inside the connecting channel 213, is more convenient for processing, and can provide sufficient structural strength with the simplest structure.

[0056] In some specific embodiments, the rib plate 2141 can also be a Y-shaped plate (not shown in the drawings). The structure of the rib plate 2141 is to add a triangular support body at the position of the rib plate 2141 close to the first plate body 211 on the basis of the above straight plate structure, so that the rib plate 2141 is split in the middle to form a Y shape, and further the first cavity 2131 and the second cavity 2132 are separated into two cavity channels farther from the above straight plate structure in the direction from the middle to the first plate body 211. Preferably, a connecting plate is provided between the two first open ends 215 formed by the first cavity 2131 and the second cavity 2132 on the first plate body 211, and the connecting plate is connected to the first plate body 211 up and down. The use of the triangular support body can further enhance the connection strength and support strength between the connecting channel 213 and the first plate body 211, so as to have a better buffering effect on the lateral impact generated from the center pin direction to the side wall direction of the cross beam 100.

[0057] In some specific embodiments, such as Figure 3 shown, in order to increase the connection strength between the reinforcing rib 214 and the top and bottom plates of the connecting channel 213, it is preferred that the reinforcing rib 214 further includes a thickened position 2142. The thickened position 2142 is constructed at the connection between the rib plate 2141 and the top plate of the connecting channel 213; and / or, constructed at the connection between the rib plate 2141 and the bottom plate of the connecting channel 213.

[0058] In some specific embodiments, such as Figure 3 shown, in order to avoid stress concentration at local positions, it is preferred to provide chamfers or rounded corners around the first opening end 215 where the first cavity 2131 and the second cavity 2132 are connected to the first plate body 211. Similarly, chamfers or rounded corners are provided around the second opening end 216 where the first cavity 2131 and the second cavity 2132 are connected to the second plate body 212.

[0059] In some embodiments, such as Figure 4 shown, the stop portion 220 includes a stop body and a mounting plate 222. The stop body is fixedly connected to one side of the mounting plate 222, and the other side of the mounting plate 222 is fixedly connected to the second plate body 212 of the connecting portion 210. A stop end face 221 with a gradually decreasing cross-section is constructed on the side of the stop body facing away from the mounting plate 222, and the stop end face 221 faces the center pin. The area of the stop end face 221 is smaller than the connection surface between the stop body and the mounting plate 222, in order to improve the stop accuracy between the stop portion 220 and the center pin and avoid damaging the center pin during the lateral stop of the lateral stop seat 200.

[0060] Based on the specific structure of the above-mentioned lateral stop seat 200, such as Figure 1 shown, in the bogie provided by the embodiment of the present invention, the stop portions 220 of a pair of lateral stop seats 200 are arranged opposite to each other in the lateral direction of the vehicle body, so as to ensure that the center pin can be accurately connected between the pair of lateral stop seats 200, ensure that the pair of lateral stop seats 200 and the center pin can be longitudinally centered and perform a reliable lateral stop function, avoid the center pin from deviating left and right laterally relative to the frame, and increase the overall connection accuracy between the frame of the bogie and the center pin.

[0061] In some embodiments, such as Figure 1As shown, the frame includes a cross beam 100 and a pair of longitudinal beams. The cross beam 100 is preferably a rectangular frame structure made of carbon fiber, which can improve the strength of the cross beam 100 on the basis of meeting the maximum requirement of vehicle body lightweight, and provide a reliable installation foundation for the lateral stop seat 200. Preferably, the cross beam 100 includes a pair of cavities, the pair of cavities extend along the longitudinal direction of the bogie respectively, and the pair of cavities are symmetrically arranged on the lateral sides of the cross beam 100 respectively, so that the pair of longitudinal beams can pass through the pair of cavities respectively. The cavities extending along the longitudinal direction can increase the connection length between the cross beam 100 and the longitudinal beams, and provide sufficient space positions for the installation of other components of the frame. For example Figure 1 As shown, a pair of lateral stop seats 200 are respectively connected to the side walls of the pair of cavities, and the side walls of the cavities face the center pin.

[0062] In some specific embodiments, the lateral stop seat 200 is fixedly connected to the side wall of the cavity of the cross beam 100 through the entire surface of the first plate body 211. Compared with the installation structure of the traditional lateral stop seat 200, the installation area of the lateral stop seat 200 is increased, and the connection strength and reliability are both increased significantly. Moreover, during the installation process, there is a large redundant space for centering the pair of lateral stop seats 200 on the side walls of the cavities of the cross beam 100, which improves the assembly accuracy and convenience of the frame, and also facilitates the maintenance, disassembly and separation.

[0063] Thus, the rail vehicle of the embodiment of the present invention by setting the above-mentioned lateral stop seat 200 or the above-mentioned bogie enables the rail vehicle to at least have all the advantages of the above-mentioned lateral stop, which will not be elaborated here specifically.
