[0027] The present application will be described in detail below with reference to the specific embodiments shown in the accompanying drawings.

[0028] In the various drawings of the present application, for the sake of convenience of illustration, some dimensions of structures or parts are exaggerated relative to other structures or parts, and therefore, are only used to illustrate the basic structure of the subject matter of the present application.

[0029] It should be understood that although the terms first, second, etc. may be used in this document to describe various elements or structures, these described objects should not be limited by these terms. These terms are only used to distinguish these described objects from each other.

[0030] An embodiment of the present application provides a rail vehicle, referring to Figures 1 to 3 The rail vehicle includes a clamp 100, a bogie, and a connecting assembly 200 for connecting the clamp 100 and the bogie, that is, the connection between the clamp 100 and the bogie is achieved through the connecting assembly 200.

[0031] See also Figure 2 The connecting assembly 200 includes a bogie hanger 1, a clamp hanger 2, a first connecting member 3 and a second connecting member 4. The bogie hanger 1 is connected to the bogie, and the clamp hanger 2 is connected to the clamp 100.

[0032] See also Figure 4 The bogie hanger 1 is provided with a first hole 11 and a second hole 12 which are perpendicular to each other. Figure 5 The clamp hanger 2 is provided with a third hole 21.

[0033] See also Figure 6 The first connecting member 3 is provided with a threaded hole 31 , and the first connecting member 3 is configured such that when the first connecting member 3 is inserted into the first hole 11 , the threaded hole 31 is aligned with the second hole 12 .

[0034] The second connecting member 4 is configured as follows: the second connecting member 4 can pass through the third hole 21 and the second hole 12 in sequence and be threadedly connected with the threaded hole 31 .

[0035] The connection between the bogie hanger 1 and the clamp hanger 2 can be achieved through the first connecting member 3 and the second connecting member 4. Specifically, the second connecting member 4 is passed through the third hole 21, the second hole 12, and the threaded hole 31 in sequence from the side of the clamp hanger 2 away from the bogie hanger 1, and then threadedly matched with the threaded hole 31, thereby achieving the connection between the clamp hanger 2 and the bogie hanger 1. In addition, since the first connecting member 3 is inserted into the first hole 11 and the first hole 11 is perpendicular to the first hole 11, the first connecting member 3 can be prevented from escaping from the first hole 11 after the connection is completed. Furthermore, when the threaded hole 31 fails or is damaged after being used for a period of time or a fault occurs in the threaded hole 31, the first connecting member 3 can be taken out, and only the first connecting member 3 needs to be replaced, which is easy to operate and greatly saves costs.

[0036] Specifically, during assembly, the first connecting member 3 is first inserted into the first hole 11 of the bogie hanger 1, and then the second connecting member 4 is sequentially passed through the third hole 21 of the clamp hanger 2 and the second hole 12 of the bogie hanger 1, and finally enters the threaded hole 31 of the first connecting member 3 for threaded connection.

[0037] See also Figure 6 In one embodiment, the first hole 11 is a through hole, and a first anti-slip portion 32 is provided at one end of the first connector 3. When the first connector 3 is inserted into the first hole 11, the anti-slip portion abuts against the bogie hanger 1 and restricts the first connector 3 from falling off from the first hole 11 along its insertion direction. The first hole 11 is set as a through hole, which can be easily processed; by setting the first anti-slip portion 32, when the first connector 3 is inserted into the first hole 11 in advance, the first connector 3 can be prevented from falling off directly and the subsequent matching cannot be completed, and the first connector 3 can be positioned. When the first anti-slip portion 32 abuts against the bogie hanger 1, the threaded hole 31 is just aligned with the second hole 12, so that the matching of the second connector 4 can be achieved.

[0038] Specifically, the first connecting member 3 may be a pin, and the cross-sectional shape of the pin may be circular or square, or may be other shapes. It is only necessary to set the shape of the first hole 11 to match the pin.

[0039] The first anti-slip portion 32 may be configured as a boss, and the boss may be in a circular, square, or other shape as long as its cross-sectional area is larger than that of the first hole 11 .

[0040] See also Figure 1 to Figure 2In one embodiment, a second anti-slip portion 41 is provided at one end of the second connecting member 4, and the connecting assembly 200 further includes a sleeve 5, which is sleeved on the outer periphery of the second connecting member 4, and the sleeve 5 is configured as follows: when the second connecting member 4 is fitted in the threaded hole 31, the sleeve 5 is located on the side of the clamp hanger 2 away from the bogie hanger 1, and the two ends of the sleeve 5 respectively abut the clamp hanger 2 and the second anti-slip portion 41.

[0041] The sleeve 5 can increase the effective pressing length of the clamp hanger 2, thereby improving the connection strength of the connecting assembly 200 and improving the safety of use.

[0042] In a preferred embodiment, the first connecting members 3 correspond to the first holes 11 one by one and are each provided with two, thereby improving the overall connection strength of the connecting assembly 200, improving the safety of use, and also avoiding a decrease in the strength of the bogie hanger 1 itself due to an excessive number of the first holes 11.

[0043] Of course, in other embodiments, the number of the first connecting members 3 and the first holes 11 can also be reasonably set according to the volume of the bogie hanger 1 .

[0044] In a preferred embodiment, the ratio of the number of the first holes 11 to the number of the second holes 12 is 1:2, each of the first holes 11 is connected to two of the second holes 12, each of the first connecting members 3 is provided with two of the threaded holes 31, and when the first connecting member 3 is inserted into the first hole 11, the second holes 12 are aligned one by one with the threaded holes 31. In this way, the structure of the connecting assembly 200 can be simplified while improving the connection strength.

[0045] The third holes 21 are arranged in a one-to-one correspondence with the second holes 12 , that is, the number of the third holes 21 is equal to the number of the second holes 12 .

[0046] In one embodiment, the connection assembly 200 further includes an anti-rotation mechanism.

[0047] Combination Figures 1 to 5 In one embodiment, the anti-rotation mechanism includes a key 6 and a keyway 7 that cooperate with each other, the key 6 is arranged on one of the bogie hanger 1 and the clamp hanger 2, and the keyway 7 is arranged on the other of the bogie hanger 1 and the clamp hanger 2.

[0048] Through the cooperation of the key 6 and the key slot 7, not only can the relative rotation of the bogie hanger 1 and the clamp hanger 2 be prevented, further improving the connection strength of the connecting assembly 200, but also the force generated by friction braking during the braking process can be transmitted to the bogie hanger 1 during the operation of the vehicle, and the relative positions of the bogie hanger 1 and the clamp hanger 2 can be limited.

[0049] In this embodiment, the key 6 is arranged on the bogie hanger 1, and the key slot 7 is arranged on the clamp hanger 2 to prevent the strength of the bogie hanger 1 from being reduced due to the simultaneous arrangement of the first hole 11 and the key slot 7. On the contrary, the key 6 can serve as a reinforcing rib through its arrangement.

[0050] In other embodiments, the setting positions of the key 6 and the key slot 7 may also be interchanged, that is, the key slot 7 is set on the bogie hanger 1, and the key 6 is set on the clamp hanger 2, as long as the strength of the bogie hanger 1 and the clamp hanger 2 is guaranteed.

[0051] Preferably, the extension direction of the first hole 11 is perpendicular to the extension direction of the keyway 7, so as to disperse the force on the first connecting member 3 and the key 6 or keyway 7, avoiding the first hole 11 in the bogie hanger 1 from being easily damaged due to force concentration.

[0052] When there are multiple third holes 21, the multiple third holes 21 are arranged in an array, and the multiple third holes 21 are dispersedly arranged on both sides of the key 6 or the key slot 7. Correspondingly, the second holes 12 are also arranged in an array.

[0053] See also Figure 5 In one embodiment, the keyway 7 includes a main body 71 and an arc-shaped portion 72 located at a corner of the main body 71 , and the key 6 is fitted in the main body 71 . The setting of the arc-shaped portion 72 can reserve a certain installation gap for the key 6 during installation, thereby reducing the friction resistance during installation and facilitating the key 6 to be fitted into the keyway 7 .

[0054] In one embodiment, the cross-section of the keyway 7 is rectangular, and the keyway 7 includes a first section 73, a second section 74 and a third section 75 sequentially connected along its length direction, and the width of the second section 74 is greater than the width of the first section 73 and the third section 75, thereby reducing the friction resistance when the key 6 is installed in the keyway 7, thereby facilitating the key 6 to be matched in the keyway 7.

[0055] In one embodiment, the second connecting member 4 includes a threaded section and a smooth section, the smooth section is located between the threaded section and the second anti-slip portion 41, and the third hole 21 is a smooth hole. When the second connecting member 4 is matched with the clamp hanger 2, the bogie hanger 1 and the first connecting member 3, the threaded section is matched with the threaded hole 31 of the first connecting member 3, and the smooth section is matched with the third hole 21.

[0056] Specifically, the second connecting member 4 may be a bolt, and the head of the bolt is the second anti-detachment portion 41. Of course, the second connecting member 4 may also be made of other existing technologies besides the bolt, which will not be described in detail herein.

[0057] In other embodiments, the anti-rotation mechanism may also be configured to include an internal thread provided in the third hole 21 and an external thread provided in the second connecting member 4 .

[0058] When the second connecting member 4 is matched with the clamp hanger 2, the bogie hanger 1 and the first connecting member 3, the external thread of the second connecting member 4 is matched with the internal thread in the third hole 21 and the threaded hole 31 of the first connecting member 3, thereby preventing the bogie hanger 1 and the clamp hanger 2 from rotating relative to each other.

[0059] In summary, the connection assembly 200 for connecting the clamp 100 and the bogie and the rail vehicle having the same provided in the present application can realize the connection between the bogie hanger 1 and the clamp hanger 2 through the first connecting member 3 and the second connecting member 4. Specifically, the second connecting member 4 is passed through the third hole 21, the second hole 12, and the threaded hole 31 in sequence from the side of the clamp hanger 2 away from the bogie hanger 1, and then threadedly engaged with the threaded hole 31, thereby realizing the connection between the clamp hanger 2 and the bogie hanger 1. Moreover, since the first connecting member 3 is inserted into the first hole 11, and the first hole 11 is perpendicular to the second hole 12, the first connecting member 3 can be prevented from escaping from the first hole 11 after the connection is completed. Furthermore, when the threaded hole 31 fails or is damaged after being used for a period of time or a fault occurs in the threaded hole 31, the first connecting member 3 can be taken out, and only the first connecting member 3 needs to be replaced, which is easy to operate and greatly saves costs.
