Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
A guide boom 100 for a rail vehicle (not shown) according to an embodiment of the present invention will be described with reference to fig. 1 to 14.
As shown in fig. 1 to 14, a guide boom 100 for a rail vehicle according to an embodiment of the first aspect of the present invention comprises a first guide boom segment 110, a second guide boom segment 120 and a third guide boom segment 130.
Specifically, the second boom guiding segment 120 is connected to the first boom guiding segment 110, and the width of the second boom guiding segment 120 is smaller than the width of the first boom guiding segment 110. The third boom guiding segment 130 is connected to an end (e.g., the right end in fig. 1) of the second boom guiding segment 120 away from the first boom guiding segment 110, and the width of the third boom guiding segment 130 is smaller than that of the second boom guiding segment 120. Here, a direction from the first cantilever guide segment 110 to the third cantilever guide segment 130 is a longitudinal direction of the cantilever guide 100, a direction perpendicular to the longitudinal direction in a plane in which the cantilever guide 100 is located is a width direction of the cantilever guide 100, and the width of the first cantilever guide segment 110, the width of the second cantilever guide segment 120, and the width of the third cantilever guide segment 130 are dimensions of the first cantilever guide segment 110, the second cantilever guide segment 120, and the third cantilever guide segment 130 in the width direction of the cantilever guide 100, respectively. The first guiding arm section 110 and the second guiding arm section 120 are smoothly transited, and the second guiding arm section 120 and the third guiding arm section 130 are smoothly transited.
The third guide cantilever segment 130 includes a guide wheel mount. The guide boom 100 is adapted to mount a guide wheel 210 of a bogie 200 of the rail vehicle via a guide wheel mount of the third guide boom section 130. The guide boom 100 is suitable for being connected with the slewing bearing 236 of the bogie 200 through the first guide boom section 110, and because the bending moment borne by the first guide boom section 110 is greater than the bending moment borne by the third guide boom section 130, the first guide boom section 110, the second guide boom section 120 and the third guide boom section 130 of the guide boom 100 are sequentially reduced along the length direction and the width of the guide boom by the arrangement, so that the distribution and the structural form of the bending moment of the boom are met, the bearing capacity is good, the force transmission is fast and accurate, and the occupied space is small.
When the guide cantilever 100 is applied to a rail vehicle, because both ends of the 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 conformity with a rail beam surface, and after the guide wheel 210 receives a force transmitted by the rail beam surface, the force is transmitted to the guide cantilever 100, and the guide cantilever 100 can quickly transmit a 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 cantilever 100 for the rail vehicle of the embodiment of the invention, the width of the second guide cantilever section 120 is smaller than that of the first guide cantilever section 110, the width of the third guide cantilever section 130 is smaller than that of the second guide cantilever section 120, and the first guide cantilever section 110 and the second guide cantilever section 120 are in smooth transition and the second guide cantilever section 120 and the third guide cantilever section 130 are in smooth transition, so that the guide cantilever 100 has a small weight and a small 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 guiding cantilever segment 110 is smaller than the thickness of the second guiding cantilever segment 120, and the thickness of the second guiding cantilever segment 120 is smaller than the thickness of the third guiding 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, 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 100 gradually changes in a 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 100 smoothly transitions from one end thereof toward the other along the length of the guide cantilever. The thickness of the guide boom 100 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. 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 may include 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 a concave curved section and a 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 concave curved section of the first side wall 1111 and an end of the third side wall 1113 near the first guide cantilever segment 110, and the fourth side wall 1114 is connected between a free end of the convex curved section of the first side wall 1111 and an end of the third side wall 1113 near the third guide cantilever segment 130. So set up, can be better conduct the power from fourth lateral wall 1114 to second lateral wall 1112 through first lateral wall 1111 and third lateral wall 1113 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 reliability of traveling.
Further, as shown in fig. 2, 4, 10 and 12, the plurality of reinforcing beads includes: the first reinforcing rib 112, the first reinforcing rib 112 includes 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 to the second sidewall 1112, and the other end of the second reinforcing segment 1122 and the other end of the third reinforcing segment 1123 are connected to the first sidewall 1111 and the third sidewall 1113, respectively. 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 ribs 113 are shown, the two second reinforcing ribs 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 rib 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.
