Title:
ELECTRIC HYDRAULIC SYSTEM INCLUDING HYDRAULIC ACTUATOR
Document Type and Number:
Japanese Patent JP2018080768
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electric hydraulic system capable of downsizing an electric hydraulic supply source even with constitution necessary for large hydraulic force, such as a leg lifting/lowering system.SOLUTION: An electric hydraulic system 10 is constituted as an independent hydraulic system, which is, for example, applied to a leg lifting/lowering system and includes a first hydraulic actuator 31 intermittently operating. The electric hydraulic system 10 includes: an electric hydraulic supply source (hydraulic pump 11 and an electric motor 12 configured to drive the hydraulic pump) configured to supply oil pressure to the first hydraulic actuator 31; and an accumulator 13 configured to accumulate hydraulic force from the electric hydraulic supply source, and supply the accumulated oil pressure to the first hydraulic actuator 31 in order to operate the first hydraulic actuator 31.SELECTED DRAWING: Figure 1
