Abstract
A hydraulic system for a concrete mixer vehicle including an electronically controlled variable displacement hydraulic pump, a distribution manifold fluidly coupled to the hydraulic pump, a hydraulic fan motor coupled to a fan and fluidly coupled to the distribution manifold, an auxiliary system fluidly coupled to the distribution manifold, and a controller structured to: determine a total system demand based at least in part on a fan motor demand and an auxiliary system demand, adjust a displacement of the hydraulic pump to satisfy the total system demand, and operate the hydraulic pump at a pump speed to satisfy the total system demand.
