Abstract: This paper introduces a road spectrum collection and bench application method based on dual clutch transmission, through the early real vehicle collection of road spectrum data, conversion to synthetic road spectrum bench test specification, carry out Bench Road spectrum test of powertrain level and evaluate the quality of dual clutch automatic transmission. The test results show that the same result between the Road load spectrum bench test and vehicle test, which is a sufficient hardware verification replacement of vehicle test.
Key Words: Road Spectrum Test; Double Clutch Automatic Transmission; Bench Test
前 言
雙離合器自動變速器(Double clutch transmission,又稱DCT)是當前各類乘用車使用的常見變速器之一,其以MT(Manual Transmission 手動變速器)為結(jié)構(gòu)原型,增加了雙離合器、電液控制器、TCU(transmission control unit變速器控制單元)等結(jié)構(gòu),實現(xiàn)了在整車上的自動換擋、傳輸扭矩的作用。(剩余5125字)
