摘要： An accumulator (100) for a hydraulic system, wherein the accumulator (100) comprises a liner (110), a piston (140) and a housing (200), that defines a pressure chamber (PC), for receiving hydraulic fluid at high pressure, wherein the piston (140) is biased towards an end position of the pressure chamber (PC) for interacting with the hydraulic fluid in the pressure chamber (PC), and the piston (140) is movable in a predetermined range for accumulating hydraulic fluid. The accumulator has at least one outlet port (111) in a sidewall (112) of the liner (110), which outlet port (111) is covered by the piston (140) in the predetermined range and is uncovered when the piston (140) has moved a predetermined distance from the end position. A hydraulic system is also provided that comprises the above accumulator and an all-wheel drive system comprising the above hydraulic system. A method for de-airing an accumulator according to above is also provided.

摘要： The present invention relates to a method of controlling a hydraulic system (100) for an all-wheel drive system, said hydraulic system comprising an electric hydraulic pump (110), a control valve (140) for directing hydraulic fluid to a load, and an accumulator (150) in fluid communication with the pump (110) and the valve (140). The method comprises the steps of estimating a negative hydraulic-fluid leakage flow out of the accumulator (150), such as through the valve (140) and the pump (110), using a predetermined model, estimating a negative hydraulic-fluid work flow through the valve (140), by studying the control signal from an ECU (170) to the control valve (140) and using a predetermined model, and estimating a first positive fluid flow from the pump (110) into the accumulator (150), from a control signal from the ECU (170). The above estimated negative hydraulic-fluid leakage flow, negative hydraulic-fluid work flow and positive fluid flow are added to a total flow communicating with the accumulator (150), and a value is obtained of the volume of the hydraulic fluid in the accumulator (150) from said total flow communicating with the accumulator (150) for controlling an operation mode of said pump (110). The invention also relates to a computer-readable medium for holding a computer program for carrying out the above method, and also a hydraulic system for performing the method.
