Loader's mechanical drive controller

摘要

The present invention relates to a power machine''s power system (220) having dual in-line pumps (524A, 524B) configured to provide hydraulic fluid to each of the left and right movement motors of the power machine and a power machine (100, 200) employing the power system. Initiate. In one embodiment, pump pintle arm controllers 410, 515A, 515B and a single centering mechanism 410 of the pintle arm controllers are provided. A single centering mechanism is configured to center each pintle arm of the two pumps. In some exemplary embodiments, it also includes a mechanical control linkage 415 structure that allows the separate pump pintle arm controllers to be positioned substantially behind each other on the side of the pump. This allows the hydraulic connection 425 to the pump to be located at the top of the pump assembly and improves the routing of the hydraulic hoses in the power machine.
