Description

technical field [0001] The invention belongs to the technical field of automobile rain test, in particular to a heavy-duty automobile rain test system and process. Background technique [0002] During the use of automobiles, its airtightness is often one of the factors that customers are most concerned about. Water seepage or water ingress in vehicles will bring economic losses to customers, and it will also make customers feel insecure. The rain tightness test is an indispensable and important link. Whether it is a passenger car, a car, a mini-car or a truck, it is very important to create a good working environment for the drivers and passengers and ensure their safety. [0003] Different from ordinary small cars such as cars, heavy-duty trucks are mainly exposed to rain in the cab. The rain laboratory cannot meet the requirements of the heavy truck rain test, especially in winter when the weather is cold. After the vehicle rain test, the rain water dripping on the groun...

AI Technical Summary

Problems solved by technology

[0004] At present, all heavy-duty vehicle manufacturers have no good solution to the problem of how to conduct winter tests. Although some manufacturers conduct winter rain tests, they have many problems such as occupying a large area of ​​production land, high energy consumption, and low efficiency.
