Hydraulic fluid cooling system for pair of integrated hydrostatic transmissions
A hydraulic fluid cooling system for a pair of integrated hydrostatic transmissions includes a common reservoir holding hydraulic fluid and having hydraulic lines connecting the common reservoir to each integrated hydrostatic transmission, a hydraulic fluid reservoir inside each integrated hydrostatic transmission, and a pump for pumping fluid from each transmission's hydraulic fluid reservoir to the other transmission. Hydraulic fluid lines link each transmission's hydraulic fluid reservoir to the other transmission. The system pumps hydraulic fluid from the sump or reservoir of each integrated hydrostatic transmission to the other transmission, providing the cooling capacity of a non-loaded transmission to cool hydraulic fluid for a fully loaded transmission.
