High-temperature environment simulation test system of commercial vehicle

Abstract

The invention provides a high-temperature environment simulation test system of a commercial vehicle. The test system comprises a high-temperature environment simulation system, an engine tail gas exhausting system and drum test equipment, wherein the high-temperature environment simulation system leads high-temperature air into the test system through an air supply unit with an electric heating function so as to perform high-temperature environment simulation of the test system. Through the high-temperature environment simulation test system of the commercial vehicle provided by the invention, the test cost of the commercial vehicle is reduced, and the test period is shortened.

Description

technical field [0001] The invention belongs to a test system for the performance of a complete vehicle, in particular to a high-temperature environment simulation test system for a commercial vehicle. Background technique [0002] According to the revision of the ISO3833 standard, cars are divided into only two categories: passenger cars and commercial vehicles. [0003] A commercial vehicle is an automobile designed and technically characterized for the transport of people and goods. Since 2005, my country's auto industry has implemented a new statistical classification of vehicle models. Compared with the old classification, commercial vehicles include all trucks and passenger cars with more than 9 seats. In the old classification, the chassis sold by the complete vehicle enterprises were included in the statistics of the complete vehicle. In the new classification, the chassis are listed separately, which are incomplete passenger car vehicles (bus chassis) and incomple...

AI Technical Summary

Problems solved by technology

[0005] At present, my country's multi-axle drive commercial vehicles do not have a drum test bench to test the performance of the whole vehicle, and can only conduct field sports car tests

In particular, the high-temperature environment test needs to be carried out in Hainan, Nanjing and other places in summer, which not only requires the formation of a huge test team, but also requires a lot of manpower and material resources, and prolongs the test cycle; moreover, the test on the road is greatly affected by time and place, and environmental factors are not easy to control. The repeatability is not good, it is impossible to carry out in-depth research on the vehicle and subsystem technology, and it is difficult to provide the necessary technical reserves for newly developed vehicles
