Engine front-end gear train accessory endurance test control system

Abstract

The invention discloses an engine front-end gear train accessory endurance test control system. The system comprises a controller, a system air conditioner compressor, a power-assisted steering pump,a generator, an air conditioner compressor load loading device, a power-assisted steering pump load loading device, a generator load loading device and an environment temperature control device. An engine idling state monitoring unit, an air conditioner compressor endurance test control unit in signal connection with the air conditioner compressor load loading device, a power-assisted steering pump endurance test control unit in signal connection with the power-assisted steering pump load loading device, and a generator endurance test control unit in signal connection with the generator load loading device are arranged in the controller. The design not only realizes the unified, rapid and accurate test of the durability of an engine front-end gear train accessory, but also does not need tooccupy the resources of an engine rack.

Description

technical field [0001] The invention belongs to the field of automobile engine testing, and in particular relates to a control system for the durability test of an engine front end gear train accessory. Background technique [0002] The gear train accessories at the front end of the automobile engine work under high engine room ambient temperature and changing workload conditions. In order to ensure the reliability of the engine front gear train accessories, durability tests are usually required. At present, during the verification process of the engine durability test, the assessment of the front-end gear train accessories lacks a corresponding targeted bench test assessment method. It is often assessed by carrying other conventional endurance tests or the durability of the whole vehicle. The durability assessment is single, the conditions are not strict, and periodic Long, unable to achieve the purpose of durability assessment and verification of front-end gear train acces...

Problems solved by technology

At present, during the verification process of the engine durability test, the assessment of the front-end gear train accessories lacks a corresponding targeted bench test assessment method. It is often assessed by carrying other conventional endurance tests or the durability of the whole vehicle. The durability assessment is single, the conditions are not strict, and periodic Long, unable to achieve the purpose of durability assessment and verification of front-end gear train accessories; at the same time, for the developed engine front-end gear train durability test method, there is a lack of corresponding test control system to control the operation of each accessory loading device in accordance with the durability test method; the engine bench control system is adopted Loading the front-end gear train accessories, there are problems such as long debugging period, high cost of remanufactured bench, and long time of bench resources occupied by endurance test
