Alternating-current synchronous quantitative electromechanical liquid coupler

Abstract

The invention relates to an alternating-current synchronous quantitative electromechanical liquid coupler. The coupler comprises a shell, the shell is internally provided with a mechanical energy assembly, a swash plate hydraulic energy assembly and an electric energy assembly. The mechanical energy assembly comprises a transmission shaft, and the front end of the transmission shaft extends out ofthe shell; the swash plate hydraulic energy assembly comprises a swash plate, a cylinder body and a flow distribution disc; the cylinder body is connected to the transmission shaft through a key; thecylinder body comprises plunger holes, a plunger and a sliding shoe, the bottom surface of the sliding shoe is tightly attached to the wedge surface of the swash plate and slides; the rear portion ofthe cylinder body is tightly attached to the flow distribution plate; the electric energy assembly comprises three stator iron cores, a rotor and stator windings, and the three stator iron cores arefixedly connected with the interior of the shell; the stator windings which are connected in series are wound around the peripheries of the stator iron cores, lead terminals U1, U2 and U3 are connected between the stator windings, the rotor is a permanent magnet fixed outside the cylinder body, the poles of the rotor are reversely arranged, mechanical energy, hydraulic energy and electric energy can be converted mutually, any one type of energy can be converted into the other two types of energy at the same time, and any two types of energy can be converted into the other type of energy at thesame time.

[0002] Power devices such as generators, electric motors, swash plate hydraulic pumps or hydraulic motors, and electric motor-hydraulic pump combination systems are currently widely used, and the corresponding patents are also numerous, but the above-mentioned equipment has a series of disadvantages: (1) The functions are relatively single For example, the generator converts other forms of energy into electrical energy, the motor converts electrical energy into mechanical energy, the swash plate hydraulic pump or hydraulic motor realizes the mutual conversion of hydraulic energy and mechanical energy, and the motor-hydraulic pump combination system realizes the conversion of electrical energy into hydraulic energy. Etc.; (2) The structure of the motor-hydraulic pump and other combined systems is relatively loose, with many energy conversion and transmission links, low efficiency, and unreasonable matching problems; There are many occasions for hydraulic energy or mechanical energy, such as automobiles, construction machinery, etc.; (4) The trend of electrification in the fields of transportation and engineering construction is becoming more and more obvious, and the proportion of electric energy is getting higher and higher, and electric energy and other forms of energy are transformed into each other The demand for power equipment is becoming more and more urgent, but the above power equipment cannot flexibly meet this demand; (5) There is no power equipment that can realize the mutual conversion of the three kinds of energy of electromechanical and hydraulic at the same time, and better realize the heavy-duty Recovery and reuse of vehicle braking energy
