A loading detection and control method applied to a heavy truck gearbox loading test bench

Abstract

The invention discloses a loading testing and control method applied on a heavy truck transmission loading testing bench. The method comprises the steps of connecting, performing loading testing, and performing gear shifting. The method is realized through the following hardware systems: a driving motor, a to-be-tested transmission, a load motor, a load motor connecting device, a driving motor connecting device, a testing system, a control system and a driving motor clutch. After the to-be-tested transmission enters a to-be-tested station, the driving motor and the load motor are connected with the to-be-tested transmission. In a loading testing process, one motor performs rotating speed control and the other one performs torque control, and the testing system finishes testing on the to-be-tested transmission in the process. In a gear shifting process, a motor is driven for rotating in a gear shifting rotating speed; the driving motor clutch is disconnected; the rotating speed of a torque control motor is controlled and converted to a corresponding gear shifting rotating speed; and simultaneously the gear shifting system finishes gear shifting. The method provided by the invention can realize higher tested data accuracy and higher testing efficiency. Furthermore the method facilitates analysis of various performance indexes of the transmission.

Description

technical field [0001] The invention relates to a detection and control method for a loading test bench of a heavy-duty gearbox, specifically, a loading detection and control method applied to a loading test bench for a heavy-duty gearbox. The two motors used as drive and load are respectively Speed ​​control and torque control are adopted. Background technique [0002] At present, there is little research and development of heavy truck gearbox loading test benches in China, and such large-scale test benches consume a lot of power, and ordinary loading detection and control methods cannot achieve full automation and real-time control effects. In order to meet the needs of actual control, a method is now provided. Contents of the invention [0003] The purpose of the present invention is to provide an energy-saving and high-efficiency loading detection and control method for the heavy-duty gearbox loading test bench. Two motors are used to respectively utilize the loading ...
