Abstract
Articulated steering is a common steering mode for engineering loading and mining vehicles,which is different from the steering mode of wheel deflection.It uses the relative deflection of the front and rear frames to realize steering.Articulated steering has the following characteristics:when the working device is installed on the front frame and the two frames are relatively deflected,the driving direction is always consistent with the front frame,which is conducive to quickly aligning the working surface,reducing cycle time and improving productivity,showing the unique mobility of the articulated chassis.When the articulated frame is relatively deflected,the projection of the wheel axis on the ground intersects at one point,which can avoid the side slip caused due to the deviation of wheel rolling and direction when driving in a curve,thus simplifying the steering mechanism.Therefore,even if there is no steering trapezoidal mechanism,the constant angular velocity universal joint mechanism required for deflecting the driving wheel can be removed.A dynamic model of articulated steering was established to analyze the wheel load distribution characteristics of vehicles under static and steering driving conditions,thus revealing the wheel load distribution mechanism of articulated steering vehicles,and computer simulation was performed with loader as an example.关键词
