文章通过下钻过程的运动学、动力学原理和向心涡轮变矩器、离心涡轮变矩器的涡轮反转工况性能的分析,讨论了变矩器用于下钻制动的可能性,并分别作了例题计算。文章指出,前者,通过改变柴油机转速的办法,可以进行下钻制动。但是,由于下钻速度低,不能满足正常下钻速度的要求。因此,它代替不了水刹车的液力制动;后者,对可调的单级离心涡轮变矩器导轮叶片开度的调节,可实现下钻制动,并能满足正常的下钻速度要求。文章还表明,利用充排油方案调节离心涡轮变矩器也有实现下钻制动的可能性。文章最后指出,就变矩器用于下钻制动所牵涉到的最大制动扭矩、加大散热系统以及被增速的并车链条限速等需要解决的问题作了叙述。
In this paper, by analyzing the kinematics and dynamics of the drilling process and the performance of the centrifugal turbocompressor in the turbine reversal case, the possibility of using the torque converter for down-drilling braking is discussed Respectively, made a calculation example. The article pointed out that the former, by changing the diesel engine speed approach, the drill down can be carried out. However, due to the low drilling speed, can not meet the normal drilling speed requirements. Therefore, it can not replace the hydraulic brake of water brake; the latter, the adjustable single-stage centrifugal turbine torque converter guide vane opening adjustment, to achieve down-drilling braking, and to meet the normal drilling speed Claim. The article also shows that the use of charge-discharge program to adjust the centrifugal turbine torque converter also has the possibility of drilling down. The article concludes with an account of the problems that need to be solved, such as the maximum braking torque involved in down-converter braking, the heat dissipation system and the speed limit of the speed-increasing parallel chain.
