Abstract

The invention provides a method for a simulation test of a self-changing gearbox, which is automatic in the test, low in labor intensity, and high in production efficiency, avoids industrial accidents, meets requirements for large-scale production, accurately reflects performance parameters of the self-changing gearbox, and improves the quality of the test. The invention also provides a test device using the test method. The test device comprises a conveying line and is characterized in that: the conveying line is sequentially provided with a loading station, a manual presetting station, a weighting station, a test desk, an engine oil discharge and weighing station, a dismounting preset station and a discharging station, a stopping device is arranged in front of a conveyor belt, and the test desk is connected with a computer control system. An assembled self-changing gearbox is quickly jointed with an input motor and is positioned and clamped, two output loading motors are quickly jointed with the gearbox, and the computer gives an instruction to simulate a pre-input test curve under real road conditions to do self-change test and to acquire various parameter such as the rotation speed, input torque, various pressures, flow, oil temperature, gear position and the present position of the tested gear box at the same time for analyzing through comparison with a theoretical curve and making an adjustment.

Description

(1) Technical field [0001] The invention relates to the field of equipment testing, in particular to an automatic gearbox simulation testing method, and the invention also includes a testing device using the method. (2) Background technology [0002] The existing automatic transmission test method mainly adopts manual operation static test. During the test, the transmission is hoisted to the test bench, the input motor and output motor shaft are connected to the transmission and various pipelines are connected manually, and the test is completed by manual removal. . The test process is about 45 minutes, and it does not have the function of transient simulation of the actual road conditions of the gearbox on the car. Its shortcomings are as follows: 1. Manual operation is labor-intensive and frequent work-related injuries; 2. The production cycle is slow and cannot meet the requirements of mass production; 3. It does not have a transient test function, and the test cannot si...
