連續無段變速油壓控制系統之行車效率研究
Research on Driving Efficiency for Hydraulic Control System of Continuously Variable Transmission
摘要
無段變速系統是車輛傳動發展近年來的研發重點，目的都是為了追求更高的舒適性、降低能源的損耗和更平順的傳輸效率。而目前無段變速系統是藉由電磁閥的控制，來調節在主副皮帶盤上之油壓，進而控制所需要的減速比。本研究系統為了配合現今節能的趨勢，又不影響變速箱本身優越的性能前提下，改裝一套將扭矩轉換器換成內外軸獨立建壓的機構，讓變速箱中的油壓泵浦轉速不會跟隨著主動力轉速的影響，而達到兩者能獨立運轉情形下，來追求系統中所需的最低油壓值。 本研究應用圖控程式語言LabVIEW作為監控程式的人機介面，並配合National Instruments(NI)的資料擷取系統(NI-USB 6229)來集結所需之實驗參數，並即時記錄及整合各項數據。而為了本設計系統在車輛傳輸上有明顯的動力節省需求，研究中將會在被施與負載時，利用電磁閥的相互作動，調節管路壓力裡的油壓值，並以節省管路建壓之原則，來改變主副鋼帶盤寬度而達到無段變速之目的，而藉著不同負載下所量測到的轉速功率、主副皮帶盤油壓值的變化關係，來驗證油壓控制上的效率提升。

The development of Continuously Variable Transmission system has been the mainly focused on the vehicles transmission system in recent years. Continuously Variable Transmission system can provide passengers more comfortable, reduce energy consumption and smoother transmission efficiency. Continuously Variable Transmission system is controlled by solenoid valve, two pairs of pulley and belt, thereby controlling the required gear ratio.The study of system is in line with the current trend of energy saving, without affecting the transmission itself, the premise of superior performance. The study converted a torque converter to build pressure inside and outside independent body axis, so that the speed of the oil pump is not as active force with the speed of impact, and to operate independently in the two cases, to pursue the minimum required value in system. In the present study, interaction of human machine interface was monitored through LabVIEW software installed at the platform. In addition, the analog information of the operation data and the output efficiency generated by the various components on the platform were acquired via a data acquisition system, NI-USB 6229. In order to the demand for power savings in the design system of the vehicle, through the study will be measured under different load to the power of speed, belt dr- ive primary and secondary hydraulic relationship between changes in the value, to verify oil pressure control efficiencies.
