    • An apparatus for controlling pivoting of a forklift rear axle. A hydraulic damper is arranged between a rear axle and a forklift body. The damper includes two oil chambers. The oil chambers are connected to a first passage and a second passage. A two-way switch valve is arranged between the oil chambers. The valve permits the flow of oil between the oil chambers and allows pivoting of the rear axle when opened. The valve restricts the flow of oil between the oil chambers and prohibits pivoting of the rear axle, thereby locking the rear axle when closed. When the rear axle is released from a locked state, the valve repeats a valve cycle, which includes opening and closing the valve, to regulate the amount of fluid that flows between the chambers. The valve is then kept in an opened state. This prevents shock that may be produced by sudden tilting of the body when the rear axle is released from a locked state.
    • 一种用于控制叉车后桥的枢转的装置。 液压阻尼器设置在后桥和叉车主体之间。 阻尼器包括两个油室。 油室连接到第一通道和第二通道。 在油室之间设有双向切换阀。 阀门允许油室之间的油流动,并允许后轴在打开时枢转。 阀限制油室之间的油流,并禁止后轴的枢转,从而在关闭时锁定后轴。 当后轴从锁定状态释放时,阀重复阀循环,其包括打开和关闭阀,以调节在室之间流动的流体的量。 阀然后保持打开状态。 这防止当后轴从锁定状态释放时身体的突然倾斜可能产生的冲击。
