[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figures 1 to 5 As shown, this utility model can be implemented through the following embodiments: an electromagnetic brake under load testing device, including a base 1 and a servo motor 2, a mounting plate 11 and a mounting plate 2 12 are provided on the base 1, the servo motor 2 is mounted on the mounting plate 2 12, a base 3 is mounted on the mounting plate 11, a brake under test 4 is mounted on the base 3, a rotating shaft 5 is installed inside the brake under test 4, and a load block 6 is mounted on the rotating shaft 5.

[0020] By mounting the servo motor 2 and the base 3 on the mounting plate 11 and mounting plate 12 of the base 1, and mounting the brake under test 4 on the base 3, it is convenient for the user to perform emergency braking tests on the brake under test 4. The base 3 is used to fix the brake under test 4, which is convenient to disassemble and replace the brake under test 4, and provides installation positioning to ensure the stability of the device during testing. The load block 6 is installed on the rotating shaft 5 to detect the lifespan of the brake under test 4 under emergency braking conditions under different loads.

[0021] Like 1, Figure 2 , Figure 4 and Figure 5 As shown, a fixing plate 51 is provided on the rotating shaft 5. The fixing plate 51 has a through hole 511, and the load block 6 has a through hole 61. Bolts 7 pass through the through holes 511 and 61. The fixing plate 51 is used to fix the load block 6 to prevent the load block 6 from moving on the rotating shaft 5 during testing, which would cause inaccurate data. The bolts 7 are used to fix the load block 6 to the fixing plate 51.

[0022] like Figure 1 and Figure 2 As shown, a nut 71 is installed on the right side of the fixing plate 51. The nut 71 is used to further strengthen the connection between the fixing plate 51 and the load block 6, and to prevent the bolt 7 from loosening due to excessive reaction force under emergency braking conditions, which would cause the load block 6 to detach from the fixing plate 51 during testing and result in inaccurate data; at the same time, the combination of bolt 7 and nut 71 facilitates the disassembly and replacement of the load block 6.

[0023] like Figure 1 and Figure 2 As shown, the servo motor 2 is equipped with an output shaft 21, and a connecting shaft 8 is provided between the output shaft 21 and the rotating shaft 5. The connecting shaft 8 is used to connect the output shaft 21 and the rotating shaft 5, so that the power of the servo motor 2 is transmitted to the rotating shaft 5 to simulate the emergency braking condition. At the same time, the setting of the connecting shaft 8 leaves a gap between the output shaft 21 and the rotating shaft 5, which facilitates the replacement of the load block 6 and the rotating shaft 5 to test the brake 4 under test.

[0024] like Figure 2 and Figure 3 As shown, a groove 81 is provided on the connecting shaft 8, and a flat key 9 is installed on both the output shaft 21 and the connecting shaft 8. The groove 81, in conjunction with the flat key 9, allows the power on the output shaft 21 to be transmitted to the connecting shaft 8, while ensuring stable transmission.

[0025] like Figures 1 to 3As shown, a plane 82 is provided on the connecting shaft 8, and a screw 10 passes through the plane 82. The screw 10 passes through the key 9, the output shaft 21, the connecting shaft 8, and the rotating shaft 5. The screw 10 passes through the key 9, the output shaft 21, and the connecting shaft 8, so that the rotating shaft 5, the output shaft 21, and the connecting shaft 8 are fixedly connected, preventing the connecting shaft 8 from sliding back and forth between the rotating shaft 5 and the output shaft 21, which could lead to accidental detachment and cause the testing equipment to malfunction.

[0026] The working principle of this utility model is as follows: The brake to be tested 4 is installed on the chassis. The load block 6 is inserted into the rotating shaft 5 and abuts against the fixing plate 51. Bolts 7 are inserted into the through hole 511 on the fixing plate 51 and the through hole 61 on the load block 6. Nuts 71 are installed at the ends of the bolts 7 to achieve the fixed connection between the fixing plate 51 and the load block 6. Then, the connecting shaft 8 is installed so that the connecting shaft 8 connects the output shaft 21 and the rotating shaft 5. Finally, screws 10 are inserted to fix the connecting shaft 8, the rotating shaft 5 and the output shaft 21 into one unit.

[0027] After starting the servo motor 2 and reaching a certain speed, disconnect the power supply to the brake under test 4, so that the brake under test 4 can activate the emergency braking function to achieve the test purpose.

[0028] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0029] Although this document uses a variety of terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
