[0030] The prior art provides an axle box structure in which a speed measuring gear is mounted on the end of the axle by fastening bolts. The speed measuring gear has a shift fork interface on its disc and a shift fork speed sensor is mounted axially on the speed measuring gear, thereby mounting the speed sensor on the end cover of the axle box. However, the problem is that the above mounting structure can only be used to mount the speed sensor and cannot be adapted to other external devices, such as grounding devices. If other external devices are to be mounted on the axle box, additional interfaces for the other external devices need to be set up.

[0031] In response, this embodiment provides an axle box to solve the problem that in the prior art axle box, the mounting structure for the speed sensor can only be used to install the speed sensor and cannot be adapted to other external devices. It can be used in the field of locomotive and rolling stock technology.

[0032] Reference Figures 1-3 The axle box is used to mount axles and external axle box devices. The axle box includes an axle box body 1 and an end cover 2 mounted on the axle box body 1. The end of the end cover 2 away from the axle box body 1 has an end face 21. The axle is rotatably mounted on the axle box body 1, and the axle axis passes through the center point of the end face 21. The end face 21 has an end face mounting hole 22, through which the external axle box devices are mounted. In the above axle box, the main body of the end cover 2 has a universal structure. The external axle box devices can be mounted to the end face mounting hole 22 via bolts or pins, and then to the end face 21, thus allowing the end face 21 of the end cover 2 to accommodate various external axle box devices.

[0033] In this embodiment, the external device connected to the axle box is specifically an end speed sensor 100 or a grounding device 200. The end face 21 of the end cover 2 is used to install one of the end speed sensor 100 and the grounding device 200. For example, the end face 21 is used to install the end speed sensor 100. The end speed sensor 100 is used to obtain the rotational speed of the axle, and its specific structure is as follows. Figure 2 As shown; or, a grounding device 200 is installed on end face 21. The grounding device 200 is used for grounding, and its specific structure is as follows. Figure 3 As shown. Furthermore, it is understood that the specific structure of the grounding device 200 is already a relatively mature technology in this field, and will not be described in detail here.

[0034] Alternatively, to increase the structural strength of the end cap 2, the end cap 2 may be made of aluminum alloy or stainless steel.

[0035] Continue to refer to Figures 1-3 Multiple end face mounting holes 22 are provided, and the multiple end face mounting holes 22 are arranged around the center point of the end face 21. The axle box external device can be connected to multiple end face mounting holes 22 at the same time to increase the structural strength of the connection between the axle box external device and the end face 21. In addition, the axle box external device can also be connected to the end face 21 through some end face mounting holes 22. For example, depending on the type or model of the axle box external device, different axle box external devices can be connected to some mounting holes 22 to further improve the flexibility of the connection.

[0036] Continue to refer to Figures 1-3 The end face 21 is in close contact with the surface of the external equipment of the axle box to form a seal, ensuring that the axle box can effectively protect the internal equipment under harsh working conditions. In addition, to further improve the sealing effect, the axle box also includes a sealing ring, which is disposed between the end face 21 and the external equipment of the axle box.

[0037] Continue to refer to Figures 1-3 The end cap 2 has a damper mounting part 23 for mounting the damper 300. The damper mounting part 23 has a damper mounting hole 231. The damper 300 is mounted on the damper mounting part 23 through the damper mounting hole 231, thereby connecting the end cap 2 and the damper 300, which can play a role in vibration reduction. The specific structure and vibration reduction principle of the damper 300 are already mature technologies in the field, and will not be described in detail here.

[0038] Continue to refer to Figures 1-3 The vibration damper mounting section 23 includes two mounting platforms 232, and both mounting platforms 232 are provided with vibration damper mounting holes 231. The vibration damper 300 is mounted on both mounting platforms 232 at the same time to adapt to the specific structure of the vibration damper 300 and to enable the vibration damper 300 to be mounted more stably on the vibration damper mounting section 23.

[0039] Continue to refer to Figures 1-3 The end cap 2 has a receiving cavity into which the end of the axle extends. A sensor mounting portion is provided on the side wall of the end cap 2 for mounting a lateral speed sensor 400. The lateral speed sensor 400 faces the outer peripheral wall of the axle and is used to detect the speed of the axle, thus allowing the side wall of the end cap 2 to also mount the lateral speed sensor 400. The lateral speed sensor 400 can be a conventional speed sensor in the art, and its specific structure and speed detection principle are already mature technologies in the field, and will not be described in detail here.

[0040] Continue to refer to Figures 1-3The sensor mounting part is located on the outer wall of the end cover 2, and the side wall of the end cover 2 is also provided with a through hole. The through hole connects to the receiving cavity and is used for the probe of the lateral speed sensor 400 to extend into, thereby mounting the lateral speed sensor 400 on the outer wall of the end cover 2, which can save the internal space of the end cover 2 and facilitate disassembly and assembly. As an alternative, the lateral speed sensor 400 can also be mounted on the inner wall of the end cover 2, so that the end cover 2 can also provide a certain degree of protection for the lateral speed sensor 400 and prevent the lateral speed sensor 400 from being damaged.

[0041] Continue to refer to Figures 1-3 The axle box also includes connecting bolts 3. The end cover 2 has end cover mounting holes. The connecting bolts 3 pass through the end cover mounting holes and are threadedly connected to the axle box body 1, thereby fixing the end cover 2 to the axle box body 1 and facilitating disassembly. Optionally, multiple connecting bolts 3 are provided, and the end cover 2 has multiple end cover mounting holes. Multiple connecting bolts 3 pass through the multiple end cover mounting holes one-to-one and are threadedly connected to the axle box body 1 simultaneously to improve the stability of the connection between the end cover 2 and the axle box body 1.

[0042] This embodiment also provides a locomotive and rolling stock, including the aforementioned axle box, as well as an axle and external axle box connection equipment. The axle is rotatably mounted on the axle box body 1, and the external axle box connection equipment is mounted on the end face 21 through the end face mounting hole 22. In this axle box, the main body of the end cover 2 has a universal structure, and the axle box connection equipment such as the end speed sensor 100 or the grounding device 200 can be mounted on the end face mounting hole 22 through bolts or pins and other connecting parts, and then mounted on the end face 21, so that the end face 21 of the end cover 2 can be adapted to various axle box connection equipment.

[0043] Optionally, the external device connected to the axle box is an end speed sensor 100 or a grounding device 200. The end speed sensor 100 is used to obtain the rotational speed of the axle, and the grounding device 200 is used for grounding.
