[0044] In this embodiment, it should be noted that the frame adopts an elastic suspension frame, and springs or hydraulic shock absorbers are installed between the support rollers and the frame, which can improve the smoothness of high-speed driving and reduce the damage of vibration to the equipment.

[0045] Example 4

[0046] like Figure 1 and Figure 2 As shown in the figure, another fire-fighting robot tracked chassis with a water-cooling system provided in this embodiment has the same structure as in embodiment 1. Only the different parts are described below.

[0047] In this embodiment, as Figure 2 As shown, the water-cooled circulation pipeline includes a first pipe 9, a second pipe 10, a third pipe 11, a fourth pipe 12, a fifth pipe 13, a sixth pipe 14, a seventh pipe 15, and an eighth pipe 16.

[0056] The entire system operates as follows: During filling, coolant is added to the expansion tank 6, and the water-cooled unit 4 is started to begin coolant circulation. Coolant is continuously added to the expansion tank 6 until it is full. During use, the water-cooled unit 4 is started, and the coolant flows in the circulation loop. Figure 2As shown, the coolant flows in two streams. One stream first flows through battery pack 2 to dissipate heat from it, while the other stream flows in parallel with battery pack 2. The two streams merge and then flow through the first drive motor 7 and the second drive motor 8 to dissipate heat from these two motors, which are connected in parallel. The coolant then flows to the DC-DC converter 5 to dissipate heat from it, and finally returns to the water-cooled unit 4. The water-cooled unit 4 dissipates the heat, and the expansion tank 6 is connected in parallel with the main circuit to ensure the replenishment of coolant. This achieves heat dissipation for battery pack 2, the first drive motor 7, the second drive motor 8, and the DC-DC converter 5.
