Self-leveling lift arm assembly for power machine
A lift arm assembly (300) for a power machine (200) may include a lift arm (314), an implement carrier (306), a lift cylinder (330) to raise or lower the lift arm, a leveling link (380), a tilt cylinder (376) to urge the implement carrier to pivot relative to the lift arm, and an isolated hydraulic circuit (500). The isolated hydraulic circuit may include: a slave cylinder (352) mechanically synchronized with the lift cylinder; a leveling cylinder (374) pivotably secured to the leveling link (380) and to the lift arm (314); a first conduit (508) that may provide hydraulic flow between the base end of the slave cylinder and the base end of the leveling cylinder; and a second conduit (510) that may provide hydraulic flow between the rod end of the slave cylinder and the rod end of the leveling cylinder. Movement of the slave cylinder (352) and the leveling cylinder (374) may be hydraulically synchronized by flow through first and second conduits (508, 510).
用于动力机器(200)的提升臂组件(300)可以包括提升臂(314)、器具载架(306)、升高或降低所述提升臂的提升缸(330)、调平连杆(380)、促使所述器具载架相对于所述提升臂枢转的倾斜缸(376)以及隔离的液压回路(500)。所述隔离的液压回路可以包括：与所述提升缸机械同步的从动缸(352)；可以枢转地固定到所述调平连杆(380)和所述提升臂(314)的调平缸(374)；可以在所述从动缸的基座端和所述调平缸的基座端之间提供液压流的第一导管(508)；以及可以在所述从动缸的杆端和所述调平缸的杆端之间提供液压流的第二导管(510)。所述从动缸(352)和所述调平缸(374)的运动可以通过流过第一导管和第二导管(508、510)的流而进行液压同步。
