The invention discloses an independently steerable axle for a heavy-duty vehicle. The independently steerable axle comprises an axle housing; the hydraulic oil tank is fixedly arranged in the axle housing; an oil inlet of the first motor pump is communicated with the hydraulic oil tank; the power output ends of the two hydraulic motors are respectively connected with the upper ends of the steering knuckles of the wheels on the two sides of the axle housing and are used for driving the steering knuckles to rotate; the hydraulic motor comprises a first oil way and a second oil way. When oil is fed through the first oil way or the second oil way, the rotation directions of the hydraulic motor are different; an oil inlet of the second motor pump is communicated with the hydraulic oil tank; the two hydro-pneumatic springs are arranged in one-to-one correspondence with the two lower cross arms; one end of the hydro-pneumatic spring is rotationally connected with the lower cross arm, and the other end is rotationally connected with the axle housing; an oil hole of the hydro-pneumatic spring selectively communicates with an oil outlet of the second motor pump; the two brakes correspond to the wheels on the two sides of the axle housing one to one; an oil hole of the brake selectively communicates with an oil outlet of the second motor pump.
本发明公开了一种用于重载车辆的可独立转向车桥,包括:桥壳;液压油箱,其固定设置在桥壳内;第一电机泵,其进油口与液压油箱连通;两个液压马达,其动力输出端分别与桥壳两侧车轮的转向节的上端连接,用于驱动转向节转动;其中,液压马达包括第一油路和第二油路;通过第一油路或第二油路进油时,液压马达的转动方向不同;第二电机泵,其进油口与液压油箱连通;两个油气弹簧,其与两个下横臂一一对应设置;油气弹簧的一端与下横臂转动连接,另一端与桥壳转动连接;其中,油气弹簧的油孔选择性的与第二电机泵的出油口连通;两个制动器,其与桥壳两侧车轮一一对应设置;制动器的油孔选择性的与第二电机泵的出油口连通。
