Problems solved by technology

This is because the basis of our theoretical analysis is to ensure that the belt has better mechanical performance without slipping. This analysis is feasible when the gear train is relatively simple, but as the accessory gear train becomes more and more complicated , theoretical research is difficult to ensure that the system is in the optimal state, and the actual accessory gear train may also have eccentric pulleys, inclined installation of pulleys, axis deviation of driving and driven pulleys, etc.
So now some engines have problems such as bad system stress, excessive vibration of the wheel train, or excessive noise.
[0005] Due to the above reasons, the method of obtaining a gear train layout scheme through pure theoretical analysis can no longer meet the requirements of our design.

Abstract

The invention relates to an engine belt pulley train optimization test table. It incldues table frame, motor used for simulating engine, load, support frame for mounting load and sensor for measuring parameters. On the table frame an intermediate plate is set, the motor and load are placed on one side of said itnermediate plate, the wheel train is placed on another side of said intermediate plate, and the signal output end of the sensor is connected with signal input end of computer. Said test table can simulate actual operation of the engine, and can test various related parameters in the operation processor, and the obtained various parameters can be inputted into computer. Said test table is simple in structure, convenient and safe in operation.

Description

technical field [0001] The invention relates to automobiles, in particular to test equipment used for optimizing tests on automobile engine pulley trains during the design process of automobiles. Background technique [0002] How to optimally arrange the front-end accessories of automobile engines (including air-conditioning compressors, steering pumps, motors, filters, etc.) in a limited space is a subject that requires comprehensive consideration of various factors. , The service life of the accessory system is directly related. The pros and cons of the design of the front-end attachment wheel train of the engine will directly affect the performance and reliability of the engine attachment, and then affect the technical indicators of the whole machine and vehicle. company's attention. The increasing complexity of the front-end accessory wheel trains of modern automobiles also makes the optimal design of the wheel trains a very important issue. [0003] The arrangement o...
