By fixing the heat dissipation assembly 100 and the powertrain 200 in different spaces of the vehicle body frame 300 and providing the heat insulation plate 320, the heat in the heat dissipation assembly 100 is not transferred to the powertrain 200, thus improving the heat dissipation effect of the powertrain 200.

[0055] Specifically, the interior of the vehicle frame 300 has independent spaces on the left and right sides. The independent space on the right side is the first storage space 310, and the independent space on the left side is the remaining storage space 320.

[0056] In this embodiment, the heat insulation plate is adapted to isolate the heat of the first containment space from the other containment spaces.

[0057] In this embodiment, the powertrain includes: a first motor 11, a second motor 12, a first battery pack, a second battery pack, a first reducer 21, and a second reducer 22.

[0058] The first battery pack provides power to the first motor 11, which in turn provides power to the first reducer 21. The second battery pack provides power to the second motor 12, which in turn provides power to the second reducer 22. The first reducer 21 and the second reducer 22 are diagonally distributed and drive the corresponding track drive wheels, thereby driving the track to rotate and enabling the heavy-duty, high-torque vehicle to travel.

[0059] In this embodiment, the heat dissipation assembly includes a motor heat dissipation mechanism 10; the motor heat dissipation mechanism 10 includes: a motor radiator 15, a first water pump 16, a second water pump 17, a motor cooling water tank 18, a first cooling pipe, and a second cooling pipe; the motor radiator 15, the first water pump 16, the first motor controller 13, and the first motor 11 are connected through the first cooling pipe to form a first motor heat dissipation cycle; the motor radiator 15, the second water pump 17, the second motor controller 14, and the second motor 12 are connected through the second cooling pipe to form a second motor heat dissipation cycle; the motor cooling water tank 18 is connected to both the first cooling pipe and the second cooling pipe.

[0064] It should be noted that the height of the motor cooling water tank 18 is higher than the height of the first and second motor cooling cycles. This facilitates the addition of coolant to the first and second cooling pipes by the motor cooling water tank 18. The coolant is added through the inlet 181 of the motor cooling water tank and, under the action of liquid pressure, flows into the motor radiator 15 through the outlet 182 of the motor cooling water tank, thereby entering the first and second motor cooling cycles.
