Detailed Description
Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.
A guide boom assembly for a railway vehicle according to an embodiment of the present invention will be described with reference to fig. 1-14.
As shown in fig. 1 to 14, the guide boom assembly for a railway vehicle according to the embodiment of the first aspect of the present invention includes four guide booms 100 and a slewing bearing 236.
Specifically, each guide cantilever 100 includes a first guide cantilever section 110, a second guide cantilever section 120, and a third guide cantilever section 130 that are sequentially connected, the first guide cantilever sections 110 of the four guide cantilevers 100 are sequentially connected along a circumferential direction, the third guide cantilever sections 130 of the four guide cantilevers 100 extend toward a direction away from centers of the four guide cantilevers 100, and a width of each guide cantilever 100 gradually decreases along the direction away from the centers of the four guide cantilevers 100. The width of each guide boom gradually decreases in the direction from the first guide boom section 110 to the third guide boom section 130. Here, the direction from the first guide cantilever segment 110 to the third guide cantilever segment 130 is the longitudinal direction of the guide cantilever 100, and the direction perpendicular to the longitudinal direction in the plane of the guide cantilever 100 is the width direction of the guide cantilever 100. The phrase "the width of each guide boom 100 gradually decreases in a direction away from the centers of the four guide booms 100" can be understood as the width of the first guide boom section 110, the width of the second guide boom section 120, and the width of the third guide boom section 130 are the dimensions of the first guide boom section 110, the second guide boom section 120, and the third guide boom section 130 in the width direction of the guide booms, respectively, and the smooth transition between the first guide boom section 110 and the second guide boom section 120, and the smooth transition between the second guide boom section 120 and the third guide boom section 130.
The slewing bearing 236 comprises an inner ring and an outer ring arranged outside the inner ring, the inner ring and the outer ring are relatively rotatable, and one of the inner ring and the outer ring is fixedly connected with the first guide cantilever section 110 of the four guide cantilevers 100. That is, when the inner ring is fixedly connected to the first guide boom section 110 of the four guide booms 100, the inner ring is stationary with respect to the four guide booms 100, while the outer ring is rotatable with respect to the inner ring and the four guide booms; when the outer ring is fixedly connected to the first guide boom section 110 of the four guide booms 100, the inner ring is rotatable relative to the outer ring and the four guide booms 100. The arrangement is such that the four guide booms 100 are rotatable relative to the slewing bearing 236. It is understood that the direction "outward" may be understood as a direction away from the center of slewing bearing 236, and the opposite direction is defined as "inward".
The third guide boom section 130 of the four guide booms 100 can be connected to a guide wheel 210 of a bogie 200 of a rail vehicle (not shown). For example, the third guide boom section 130 comprises a guide wheel mounting, by which each guide boom 100 is adapted to mount a guide wheel 210. Because the bending moment borne by the first guide cantilever section 110 is greater than the bending moment borne by the third guide cantilever section 130, the first guide cantilever section 110, the second guide cantilever section 120 and the third guide cantilever section 130 of the guide cantilever 100 are gradually reduced along the length direction and the width of the guide cantilever 100 by the arrangement, so that the bending moment distribution and the structural form of the cantilever are met, the bearing capacity is good, the force transmission is fast and accurate, and the occupied space is small.
When the guide cantilevers are applied to a rail vehicle, because both ends of each guide cantilever 100 are respectively connected with the guide wheel 210 and the pivoting support 236, when the rail vehicle turns, the guide wheel 210 can move in accordance with a rail beam surface, and after the guide wheel 210 receives force transmitted by the rail beam surface, the force is transmitted to the guide cantilever 100, and the guide cantilever 100 can quickly transmit acting force received by the third guide cantilever section 130 to the first guide cantilever section 110, so as to drive the traveling wheel 220 connected with the guide cantilever 100 to turn. Meanwhile, since the guide boom 100 can be fixed to one of the inner and outer relatively rotatable rings of the slewing bearing 236, relative rotation between the guide boom 100 and the axle can occur, and steering is more flexible. In this way, by adopting the guide boom 100 described above, compared with the conventional guide frame method, the guide boom 100 is small in weight and volume, which is advantageous for the light weight of the bogie 200, and is advantageous for the arrangement and installation of the guide wheels 210 and the like of the bogie 200. In addition, by adopting the guide cantilever 100, the synchronous rotation of the traveling wheels 220 can be realized, and the rotation synchronism of the traveling wheels 220 can be improved, so that the steering response speed of the rail vehicle can be improved, the steering stability of the rail vehicle can be improved, and the rail vehicle can be ensured to smoothly and synchronously turn, so that the running reliability of the rail vehicle can be improved.
According to the guide boom assembly for the railway vehicle of the embodiment of the invention, the first guide boom sections 110 of the four guide booms are sequentially connected in the circumferential direction, the width of each guide boom 100 is gradually reduced in the direction away from the centers of the four guide booms 100, and one of the inner ring and the outer ring of the slewing bearing 236 is fixedly connected with the first guide boom sections 110 of the four guide booms 100, so that the guide boom assembly has the advantages of small weight and volume, is beneficial to the light weight of the bogie 200, and is beneficial to the arrangement and installation of the guide wheels 210 and the like of the bogie 200.
According to some embodiments of the present invention, referring to fig. 1-4 and 9-12, the thickness of the first guide cantilever segment 110 is less than the thickness of the second guide cantilever segment 120, and the thickness of the second guide cantilever segment 120 is less than the thickness of the third guide cantilever segment 130. Here, it should be noted that the thickness direction of the guide cantilever 100 may be understood as a direction (for example, the vertical direction in fig. 1) perpendicular to a plane formed by the length direction and the width direction of the guide cantilever 100, and the thickness of the first guide cantilever segment 110, the thickness of the second guide cantilever segment 120, and the thickness of the third guide cantilever segment 130 are dimensions of the first guide cantilever segment 110, the second guide cantilever segment 120, and the third guide cantilever segment 130 in the thickness direction of the guide cantilever 100, respectively. With such an arrangement, the thickness of the third guide cantilever section 130 is made larger, so that the guide wheel 210 can be reliably mounted on the guide wheel mounting part; by making the thickness of the first boom section 110 smaller, the material usage is reduced while ensuring that the slewing bearing 236 can be reliably connected to the first boom section 110, thereby reducing the cost.
Further, in conjunction with fig. 1-4 and 9-12, the thickness of the guide boom gradually changes in the direction from the first guide boom section 110 to the third guide boom section 130. For example, in the examples of fig. 1-4 and 9-12, the thickness of the guide cantilever smoothly transitions from one end thereof toward the other end along the length of the guide cantilever. The thickness of the guide boom may then gradually increase from the first guide boom section 110 to the third guide boom section 130. Therefore, the structure of the whole guide cantilever can be ensured to be more stable.
According to some embodiments of the present invention, as shown in fig. 7 and 14, the height of the upper surface of each guide cantilever 100 gradually decreases along the direction of the first guide cantilever segment 110 of the corresponding guide cantilever 100 towards the third guide cantilever segment 130. The upper surface of each guide boom 100 near the end of the slewing bearing 236 is now higher and the upper surface near the end of the guide wheel 210 is lower with a smooth transition in between. So set up, can play the effect of cantilever beam better.
According to some embodiments of the present invention, as shown in fig. 2, 4, 10 and 12, the lower portions of the first guiding boom section 110 and the second guiding boom section 120 have a cavity portion 111 with an open lower side, and a plurality of reinforcing ribs are disposed in the cavity portion 111. In the description of the present invention, "a plurality" means two or more. Such a design reduces the mass of the entire guide boom 100 while ensuring the overall stiffness and strength of the guide boom 100.
Specifically, referring to fig. 2, 4, 10 and 12, the cavity portion 111 includes a first side wall 1111, a second side wall 1112, a third side wall 1113 and a fourth side wall 1114, the first side wall 1111 and the third side wall 1113 are spaced apart in a width direction of the second guide cantilever segment 120, the first side wall 1111 includes an inner concave curved section and an outer convex curved section connected to each other, the third side wall 1113 is formed as a curved section concave toward the first side wall 1111, the second side wall 1112 is connected between a free end of the inner concave curved section and an end of the third side wall 1113 close to the first guide cantilever segment 110, and the fourth side wall 1114 is connected between a free end of the outer convex curved section and an end of the third side wall 1113 close to the third guide cantilever segment 130. So set up, can be better with power from fourth lateral wall 1114 through first lateral wall 1111 and third lateral wall 1113 conduction to second lateral wall 1112 to can further improve rail vehicle's the corresponding speed that turns to, and then further guarantee rail vehicle's the stability that turns to, further improve rail vehicle's the reliability of traveling.
Further, as shown in fig. 2, 4, 10 and 12, the plurality of reinforcing beads includes: the first reinforcing rib 112 is arranged at the joint of the first cantilever segment 110 and the second cantilever segment 120, the first reinforcing rib 112 comprises a first reinforcing segment 1121, a second reinforcing segment 1122 and a third reinforcing segment 1123, one end of the first reinforcing segment 1121, one end of the second reinforcing segment 1122 and one end of the third reinforcing segment 1123 are connected, the other end of the first reinforcing segment 1121 is connected with the second side wall 1112, and the other end of the second reinforcing segment 1122 and the other end of the third reinforcing segment 1123 are respectively connected with the first side wall 1111 and the third side wall 1113. The first ribs 112 are now generally Y-shaped. So configured, the stiffness and strength at the first guide boom section 110 of the guide boom 100 can be effectively improved.
Further, as shown in fig. 2, 4, 10 and 12, the plurality of reinforcing ribs further includes: a plurality of second reinforcing ribs 113, a plurality of second reinforcing ribs 113 are provided on the second guide cantilever section 120, the plurality of second reinforcing ribs 113 are provided at intervals along the length direction of the guide cantilever, and both ends of each second reinforcing rib 113 are connected with the first side wall 1111 and the third side wall 1113, respectively. For example, in the example of fig. 2, 4, 10 and 12 two second reinforcing beads 113 are shown, the two second reinforcing beads 113 being arranged spaced apart from each other on the second guide boom section 120 and both being arranged spaced apart from the first reinforcing bead 112. Thereby, the stiffness and strength at the second guide boom section 120 of the guide boom 100 can be effectively improved, and the structure is simple.
Two second reinforcing beads 113 are shown in fig. 2, 4, 10 and 12 for illustrative purposes, but it is obvious to those skilled in the art after reading the technical solution of the present application that the solution can be applied to three or more second reinforcing beads 113, which also falls within the scope of the present invention.
According to some embodiments of the present invention, referring to fig. 1-2, 9-10, the second guide cantilever segment 120 is provided with a steering link mounting seat 121, and the steering link mounting seat 121 is formed with a steering link positioning hole 1211 and a steering link mounting hole 1212. The mounting position of the steering rod of the bogie 200 can be determined by using a positioning pin through the steering rod positioning hole 1211, and the steering rod is mounted on the guide boom by using a threaded fastener such as a bolt or the like through the steering rod mounting hole 1212. For example, in the examples of fig. 1-2, 9-10, one steering rod positioning hole 1211 and two steering rod mounting holes 1212 are shown, the steering rod positioning hole 1211 and the two steering rod mounting holes 1212 are located on the same line, and the two steering rod mounting holes 1212 are located on both sides of the steering rod positioning hole 1211.
Further, as shown in fig. 1-2, 9-10, the tie rod mount 121 projects above the upper surface of the second guide cantilever segment 120; the distance between the upper surface of the tie rod mount 121 and the upper surface of the second boom segment 120 increases gradually in the direction from the first boom segment 110 to the third boom segment 130. So set up, after guide boom 100 installed to rail vehicle, can effectively guarantee the upper surface level of steering linkage mount pad 121.
Of course, the present invention is not limited thereto, and the steering rod mounting seat 121 may not be provided on the guide boom 100 in combination with fig. 3 to 4 and fig. 11 to 12.

Therefore, by arranging the two first guide cantilevers 140 and the two second guide cantilevers 150 to be symmetrical with respect to the center of the slewing bearing 236 and only arranging the steering rod mounting seat 121 on the first guide cantilever 140, the steering rod assembly 232 can be directly mounted on any one of the two first guide cantilevers 140, the assembly efficiency can be improved, and the steering rod mounting seat 121 does not need to be arranged on the second guide cantilever 150, so that the processing technology of the second guide cantilever 150 is simplified, and the cost can be reduced. It is understood that the remaining structure of the second guide bracket 150 may be the same as that of the first guide bracket 140 except for the tie rod mount 121.
