摘要
在当前金属带式无级变速器常用的夹紧力控制方法基础上,通过台架试验标定出了临界夹紧力,并考虑温度对夹紧力的影响而引入温度修正系数;利用模糊算法选定各种不同工况下的安全系数,从而确定金属带的目标夹紧力。实车试验结果表明,应用上述方法确定的目标夹紧力,可在保证金属带不打滑的情况下,有效降低目标夹紧力,提高了金属带式无级变速器的传动效率。
Based on the conventional clamping force control method for metal V-belt continuously variable transmission （CVT）, the critical clamping force is obtained through bench test, and a temperature correction coeffi-cient is introduced for considering the effects of temperature on clamping force. Then fuzzy algorithm is used to se-lect the safety factors in various working conditions, and hence to determine the target clamping force of metal V-belt. The results of real vehicle test show that with the above-mentioned method, the target clamping force can be effectively reduced and the transmission efficiency of metal V-beh CVT is improved without slippage in metal-V-belt.
