Embodiment Construction
[0012] The specific implementation will be described below in conjunction with the accompanying drawings.
[0013] Such as figure 1 As shown, the loader two-speed steering control system in this embodiment includes a flow amplifying valve 4 , a steering cylinder 5 connected to the flow amplifying valve, a steering gear 3 , a steering pump 1 , and a two-position three-way valve 9 . Among them, the steering pump 1 is a variable displacement pump, and the steering gear 3 is a double-displacement steering gear, which has a main reversing valve 31, a first metering motor 32, a second metering motor 33, a two-position four-way hydraulic control reversing valve 34 and other components. . Steering pump 1 draws hydraulic oil from hydraulic oil tank 8 to supply oil to flow amplifying valve 4 and steering gear 3 .
[0014] The steering output ports L and R of the steering gear 3 are correspondingly connected to the a and b ports of the flow amplifying valve 4, and the oil outlet P1 of ...
