WORK MACHINE WITH ELECTRICAL AND HYDRAULIC SERVICE CENTERS

摘要

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).
