Embodiment Construction

[0023] The technical solutions of the present invention will be further described below in conjunction with the drawings and embodiments, but the protection scope of the present invention is not limited thereto.

[0024] like figure 1 As shown, an inertial device with multi-stage adjustable inertia coefficient includes a hydraulic cylinder 2, a hydraulic motor 18, a first one-way valve 7, a second one-way valve 9, a third one-way valve 14, a fourth one-way valve Directional valve 16, flywheel box 19, linear motor 20, ECU13 and sensor 12.

[0025] The hydraulic cylinder 2 is provided with a piston 4, and the piston 4 divides the cylinder body of the hydraulic cylinder into chamber A3 and chamber B5. There is an oil port B6 near the bottom of the cylinder. The oil outlet of the hydraulic motor 18 communicates with the oil port A10 through the third high-pressure hose 15 and the third one-way valve 14, and communicates with the oil port B6 through the fourth high-pressure hose ...

Abstract

The invention provides an inerter device with multistage adjustable inerter coefficients and a control method of the inerter device. The inerter device comprises a hydraulic cylinder, a hydraulic motor, a one-way valve, a flywheel box, a linear motor, an ECU and a sensor. Two flywheels with different rotational inertia are arranged in the flywheel box; the ECU determines an inertial coefficient value of the current working condition; a command is sent to the linear motor based on the smaller inertia coefficient value difference value, the linear motor drives a shifting fork shaft to move in the axial direction, such that a joint sleeve is made to be meshed with or not meshed with the joint gear ring of the flywheel with the small inertia coefficient value difference value, and therefore the output shaft of the hydraulic motor drives different flywheels to rotate, and the inertia coefficient of the whole inerter device is changed. Due to the fact that the joint sleeve is meshed with ornot meshed with joint gear rings of different flywheel, the inertia mass coefficient of the inertia volume device can be adjusted in a multistage mode, and the comfort and stability of a vehicle are improved.

Description

technical field [0001] The invention belongs to the technical field of oil-gas suspension vibration reduction, and in particular relates to an inertial device with multi-stage adjustable inertial mass coefficient and a control method thereof. Background technique [0002] Under the development trend of mechatronics in the industrial field, the mechatronics similarity theory has been extensively studied. In the traditional theory of the corresponding relationship between machinery and electronics, no matter whether the mass element corresponds to the inductance or the capacitance, it is not completely correct; because in the electronic network, the inductance, resistance, and capacitance all have two free and independent endpoints, and the mass The component is not a two-terminal component, and one end of it must be mechanically grounded; this makes the mechanical network unable to strictly correspond to the electronic network, making a large number of theories and methods of...
