[0022] Temperature monitoring mounting structure 6 is used for temperature detection inside the first brake disc 4. Temperature monitoring mounting structure 6 is installed and limited with the outer shell 3. Heat conduction plate 13 and heat conduction strip 14 are placed inside the first brake disc 4 to perform multi-point temperature detection. Heat is conducted through heat conduction plate 13 and connecting plate 12. Temperature sensor 11 provides temperature feedback through resistance change.

[0023] The temperature monitoring installation structure 6 includes a connecting rod 7, a fastening bolt 8, and a spring 9. The spring 9 and the guide rod 10 are limited by the fastening bolt 8 on the connecting rod 7, so that the spring 9 and the guide rod 10 are fixedly installed on the housing 3, and the guide rod 10 can be connected to the contact piece on the housing 3 to transmit signals.

[0024] A temperature sensor 11 is fixedly installed on the side of the connecting rod 7. A connecting plate 12 is fixedly installed at the lower end of the temperature sensor 11. The side of the connecting plate 12 is fixed to the heat-conducting plate 13 and the heat-conducting strip 14.

[0025] The heat-conducting plate 13 and the heat-conducting strip 14 are placed inside the first brake disc 4 to collect heat inside the first brake disc 4.

[0026] The control lever 1 enables the second brake disc 5 to move via the spring lever 2, thereby changing the gap between the first brake disc 4 and the second brake disc 5 and performing braking.

[0027] The connecting plate 12 conducts heat, causing the sensing element inside the temperature sensor 11 to change its resistance value as the temperature changes.

[0028] Working principle: By installing the adjusting rod 1, the lower end of the adjusting rod 1 is fixed to the second brake disc 5 via the spring rod 2, which can drive the second brake disc 5 to move. The outer shell 3 and the first brake disc 4 are kept in a fixed position. The adjusting rod 1 can be connected to an external drive mechanism, which can be a cylinder, to control the displacement adjustment of the adjusting rod 1, the spring rod 2, and the second brake disc 5. Thus, through the cooperation of the first brake disc 4 and the second brake disc 5, friction braking is performed. By installing the temperature monitoring mounting structure 6, the heat-conducting plate 13 and the heat-conducting strip 14 inside the temperature monitoring mounting structure 6 are set on the first brake disc 4, and the second brake disc 5...

The heat-conducting plate 13, the heat-conducting strip 14, and the connecting plate 12 can conduct heat, which acts on the temperature sensor 11. The temperature sensor 11 detects the temperature by the change in internal resistance, and then transmits the information through the connecting rod 7 and the guide rod 10 for real-time monitoring. The temperature sensor 11 is a WRNK2-131 model.
