【摘要】 在履带车辆各种机械式规定小半径转向基础上，增加功率不大的液压元件来获得大半径无级转向，从而显著提高车辆的高速机动性，在现代国外装甲履带车辆的转向装置中，是引人注目的发展道路之一，本文对二者复合的各类方案和理论规律予以系统分析和评比．更多还原

【Abstract】 Large radii stepless steering can be found by means of adding small power hydrostatic pump and motor,on the base of transmission with various mechanical steering mechanism,thus high speed mobility of the vehicle can be improved markedly.and it is one noticeable ingenious way to develop the transmission of modern armoured tracked vehicle. In this article,various kind of arrangements and theoretical rules of this compound steering will first be analysed and appraised systematically.更多还原
