Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of vehicles, and particularly relates to a vehicle. BACKGROUND

[0002] The cab of the vehicle is arranged on the vehicle chassis through a suspension assembly, the suspension assembly comprises a fixed support arranged on the vehicle chassis, and the cab is connected with the fixed support through elastic members to improve the stability of the cab during the driving of the vehicle. The vehicle chassis is provided with battery, motor and / or engine and electric control unit and other cooling components. During operation, the cooling components release a large amount of heat. In order to improve the heat dissipation effect, the vehicle is also provided with a cooling system. The cooling system comprises a heat dissipation assembly arranged on the cooling components. The heat dissipation assembly is connected with an expansion liquid storage pot through a heat dissipation pipe. The expansion liquid storage pot contains cooling liquid. The cooling liquid flows out of the expansion liquid storage pot and flows to the battery, motor and / or engine and electric control unit and other cooling components through the heat dissipation pipe. During the flow through these components, the cooling liquid absorbs heat, thereby reducing the temperature of the cooling components and preventing them from being damaged due to overheating. The function of the expansion liquid storage pot is to maintain the pressure stability of the cooling system and provide a space for the cooling liquid to change the volume due to temperature change. In the prior art, the expansion liquid storage pot occupies the horizontal space of the chassis. In addition, the height of the expansion liquid storage pot also needs to be considered, which occupies the vertical space of the chassis. As a result, the layout of the cooling components on the chassis needs to be adjusted to install the expansion liquid storage pot. The layout and installation of the chassis are complicated, the pipeline is messy, and the cooling liquid in the expansion liquid storage pot also needs to be supplemented in real time according to the liquid level. In addition, the upper part of the chassis also needs to be provided with an upper device and the like. The upper part of the expansion liquid storage pot cannot reserve an operation space for the operator to supplement the cooling liquid, so that the process of supplementing the cooling liquid needs to disassemble various components, which is complicated and inconvenient for the operator to operate.

[0003] In the prior art, in order to avoid the influence of the high temperature of the driving system on the cooling effect of the battery cooling liquid, multiple expansion liquid storage pots are arranged to connect the driving cooling circuit of the motor and / or engine and the cooling circuit of the battery. The multiple expansion liquid storage pots further occupy the space of the chassis, making the layout of the components in the chassis more complicated and making it more difficult for the operator to find the position of the expansion liquid storage pot, further increasing the difficulty of supplementing the cooling liquid for the expansion liquid storage pot.
