Embodiment Construction

[0014] Although this disclosure describes certain embodiments of a hydraulic system for a work machine having a hydraulic winch, the disclosure is to be considered exemplary and is not intended to be limited to the disclosed embodiments. Also, some elements or features of the embodiments disclosed herein are not limited to specific embodiments, but instead apply to all embodiments of the present disclosure.

[0015] The present application discloses a hydraulic system for a work machine including a hydraulic winch, wherein the hydraulic system is configured to prevent the hydraulic system from overheating and to reduce recovery time of the hydraulic system that has overheated. The hydraulic system includes a first travel path for cooling hydraulic fluid that has passed through a winch assembly of the work machine, and a second travel path for cooling hydraulic fluid stored in a hydraulic reservoir. Both the first path of travel and the second path of travel lead to a cooling s...

Abstract

A hydraulic system for powering a winch assembly of a work machine includes a hydraulic reservoir, a pump, a cooling system, a first path of travel, and a second path of travel. The first path of travel is disposed between the pump and the cooling system, and the winch assembly is powered by the hydraulic fluid moving along the first path of travel. The second path of travel is disposed between the pump and the cooling system. When the winch assembly is in an active condition, a first valve is in an open position such that the hydraulic fluid moves along the first path of travel and through the cooling system. When the winch assembly is in an idle condition, a second valve is in an open position such that the hydraulic fluid moves along the second path of travel and through the cooling system.

Description

technical field [0001] The present disclosure relates generally to work machines for construction applications, and in particular to hydraulic systems for work machines having hydraulic winches. Background technique [0002] Work machines (eg, track-type tractors) used in construction scenarios typically include one or more work implements (eg, blades, winches, rippers, etc.). These work tools may be operatively connected to a hydraulic system such that hydraulic fluid may be used to power the work tools. [0003] The ripper of the work machine can be raised and tilted. Hydraulic systems for these work machines typically include a first flow path for hydraulic fluid used to power the lift function of the ripper, and a second flow path for hydraulic fluid used to power the tilt function of the ripper. flow path. Scarifiers can be removed from these work machines and replaced with winches. The winch only needs to use one of the flow paths of the hydraulic system, which mea...
