The invention discloses a front wheel synchronous rotation hydraulic system and a forklift with the same. The front wheel synchronous rotation hydraulic system comprises a thin cylinder and a thick cylinder which drive a right front wheel and a left front wheel to rotate synchronously, the fixed end of the thin cylinder is connected with a steering oil cylinder seat, and the telescopic end of the thin cylinder is connected with a right front steering wheel frame. The right front wheel is rotatably mounted on a front wheel frame mounting seat through the right front steering wheel frame, a rodless cavity of the thin cylinder is communicated with a rod cavity of the thick cylinder through a connecting hose, and a rod cavity of the thin cylinder and a rodless cavity of the thick cylinder are both communicated with a steering gear oil conveying pipe. The thick cylinder and the thin cylinder are communicated in series, front wheels at the two sides are synchronously driven to rotate when hydraulic oil of a steering machine enters corresponding oil cylinders, meanwhile, the position relation of hinge points where the right wheel frame is connected with the oil cylinders and the cylinder diameters of the thick-cylinder-diameter oil cylinder and the thin-cylinder-diameter oil cylinder are matched into a certain function relation, the front wheels at the two sides can steer synchronously, and the same turning angle is achieved.

    本发明公开了一种前轮同步转动液压系统及其叉车,包括一种前轮同步转动液压系统,包括驱动右前轮和左前轮同步转动的细缸和粗缸,所述细缸固定端连接转向油缸座,其伸缩端连接右前转向轮架,所述右前转向轮架将右前轮可转动的安装到前轮架安装座上,所述细缸无杆腔通过连接软管与粗缸有杆腔连通,所述细缸有杆腔和粗缸无杆腔均与方向机输油管连通。本发明通过将粗缸和细缸串联连通,实现了转向机的液压油在进入到相应的油缸时,实现同步驱动两侧的前轮转动,同时,通过将右轮架与油缸相连的铰点位置关系和粗缸径、细缸径油缸的缸径配比成一定的函数关系,使得两侧的前轮转向不仅同步,而且还实现了同转角。
