针对某重型6×4非公路自卸车在一些严重超载等恶劣工况下出现转向沉重问题,本文从整车匹配角度进行原因分析,并提出提高助力力矩的具体改进措施。改进措施通过理论计算校核及实地试验验证,满足严重超载等恶劣工况下的使用要求,转向沉重问题得到解决。
Aiming at the heavy steering problem of a heavy duty 6 × 4 off-highway dump truck under severe conditions such as severe overloading, this paper analyzes the reasons from the point of vehicle matching and puts forward some concrete measures to improve the assist torque. The improvement measures are verified through theoretical calculation and verification in the field and meet the requirements of using under severe conditions such as serious overloading. The problem of turning to serious problems has been solved.
