Abstract

An articulated work machine (10), such as a wheel loader, includes many regularly serviced hydraulic points, such as a hydraulic fluid filter (50), a case drain filter (51), a transmission fluid filter (54) and brake accumulators (52, 53) that are grouped and mounted in a common service center subassembly (40), which may be preassembled and then later attached to the chassis when the machine (10) is being built. Likewise, an electrical service center subassembly (140) might include a battery box (144), relays and an emergency shutoff switch (150) that can be preassembled and attached to the machine chassis as a unit at the time that the work machine (10) is being built. The respective hydraulic and electrical service centers (40, 140) are attached to the work machine chassis underneath cab access steps (32, 132) on opposite sides of the machine (10). This strategy allows for a potential reduction in cost during the work machine (10) manufacture, and also better facilitates servicing of the hydraulic and / or electrical service points at an easily accessible and common location(s).

Description

Technical field

[0001] The present invention generally relates to maintenance systems related to work machines, and in particular to grouping hydraulic and / or electrical maintenance points at a common maintenance center that is easily accessible on work machines such as wheel loaders. Background technique

[0002] Work machines usually include many electrical and hydraulic systems that require periodic maintenance and / or monitoring. For example, a conventional work machine may include a hydraulic execution system including a pump and a hydraulic cylinder for operating an actuator related to the work machine. The hydraulic actuator system generally includes a case drain filter for trapping residue / debris leaving the pump and a hydraulic fluid filter for continuously trapping dirt, dust, and other particulate matter entering the hydraulic system. The internal combustion engine that powers the working machine usually includes a lubricating oil system with lubricating oil flowing thr...
