Embodiment 1

[0042] This embodiment discloses a dual-motor cooling system, which is applied to an electric vehicle and used to cool heat-generating components inside the electric vehicle.

[0043] The electric vehicle is driven by hub motor technology, and the electric vehicle includes two motors 1, and the two motors 1 are installed on two hubs at one end of the electric vehicle, such as two hubs on the front axle of the electric vehicle. The motor 1 is the main heating component inside the electric vehicle, and the dual motor 1 cooling system in this embodiment is mainly used to cool the motor 1 .

[0044] The setting of two motors 1, in addition to providing sufficient driving force, is also beneficial to the layout of the frame and chassis, because a single driving device also needs to set up an additional transmission mechanism to transmit the driving force to the two hubs, and the two hubs are respectively connected to each other. If one motor 1 is assembled, the transmission mechani...

Embodiment 2

[0064] see Figure 1 to Figure 3 , the present embodiment provides a dual-motor 1 cooling system, which includes a cooling water tank 2, a water pump 4, two buffer distribution boxes, two motors 1 and a four-in-one controller 5.

[0065] The structures and connections of the cooling water tank 2, water pump 4, two buffer distribution boxes, two motors 1 and a four-in-one controller 5 are consistent with those in Embodiment 1, the differences are:

[0066] The dual motor 1 cooling system also includes an expansion tank 6 , an emptying pipeline 7 and a water return pipeline 8 .

[0067] During the actual assembly of electric vehicles, since the assembly position of the four-in-one controller 5 is higher than that of the motor 1, some places in the pipeline of the cooling circuit 100 need to reserve elbows as vibration buffers. In this embodiment , such elbows are reserved near the four-in-one controller 5 and near the two motors 1 . The bent pipe in the pipeline system changes...

Embodiment 3

[0075] see Figure 1 to Figure 4 , the present embodiment provides a dual motor 1 cooling system, which includes a cooling water tank 2, a water pump 4, an expansion tank 6, two buffer distribution boxes, two motors 1 and a four-in-one controller 5.

[0076] The structure and connection relationship of the heat dissipation water tank 2, water pump 4, expansion water tank 6, two buffer distribution boxes, two motors 1 and a four-in-one controller 5 are consistent with the second embodiment, the difference is that:

[0077] The dual-motor 1 cooling system also includes a cooling fan 10 and a control module 11, and the air outlet surface of the cooling fan 10 faces the cooling water tank 2 (such as Figure 4 As shown), the cooling fan 10 is used to blow the cold wind from the outside to the cooling water tank 2 to force the cooling of the cooling water tank 2.

[0078] Both the motor 1 and the four-in-one controller 5 are provided with temperature sensors, and the temperature se...

Abstract

The invention discloses a buffer distribution box, a dual-motor cooling system and an electric vehicle, and relates to the technical field of vehicle motor cooling. The buffer distribution box includes a box body and three water inlets and outlets, and the three water inlets and outlets are all connected to the inside of the box body; the dual-motor cooling system includes a cooling water tank and a buffer distribution box, the cooling water tank, The buffer distribution box and the two motors are connected in series through pipelines to form a cooling circuit. The buffer distribution box buffers the cooling water by setting the box body, which can ensure that the amount of water flowing into the two motors from the cooling water tank remains equal. When used in a dual-motor cooling system, it can ensure that the two motors obtain a consistent cooling effect; the buffer distribution box Compared with complex three-way valves, it has high reliability and low maintenance costs.

Description

technical field [0001] The invention relates to the technical field of vehicle motor cooling, in particular to a buffer distribution box, a dual-motor cooling system and an electric vehicle. Background technique [0002] At present, electric vehicles, especially medium and heavy-duty electric commercial vehicles, are mainly driven by a centralized type. The centralized power generally has the characteristics of high power, while the volume / weight of the high-power electric drive system is relatively large, and the centralized power needs to occupy a large space inside the frame. Space, for this reason people have invented electric vehicles with multiple power sources driven. In this case, the power, volume and weight of each power source are relatively small. However, multiple power sources bring about a new problem, that is, each power source faces the problem of heat dissipation, and thus requires more heat dissipation components. Therefore, how to cool multiple power sou...
