Embodiment Construction

[0041] The patent of the present invention will be further described below in conjunction with the accompanying drawings and specific implementation examples, but the protection scope of the present invention is not limited thereto.

[0042] like figure 2 , image 3 and Figure 4 As shown, in the self-powered hybrid electromagnetic suspension provided by this embodiment, the upper lug 1 is hinged to the upper end of the piston rod 3, and the upper end of the piston rod 3 is provided with a semi-deep blind hole in the radial direction, and a long hole in the axial direction. The deep blind hole has a through hole along the radial direction at the lower end, and the three holes are connected to form a pipeline 2 . The piston rod 3 passes through the upper end cover 4 of the inner sleeve of the linear motor and is welded with it. The cylinder barrel 18 of the working cylinder is installed in the cylinder barrel 17 of the oil storage cylinder through the anti-pressure cover 6 a...

Abstract

The invention relates to a hybrid electromagnetic suspension system capable of realizing self-power supply and a control method thereof. Comprises an integrated structure of a linear motor and an equivalent hydraulic damper cylinder block, a suspension spring, a connecting pipeline, a hydraulic rectifier bridge, an accumulator, a hydraulic motor and a rotating electric machine, wherein the upper cavity and the lower cavity of the working cylinder are communicated with each other through the hydraulic rectifier bridge and the oil circuit, and the lower cavity is communicated with the oil storage cylinder. The ECU recognizes the pavement grade according to the received sensor signal, and switches to the corresponding mode to control the suspension, so as to obtain the optimal suspension performance under each pavement grade. The control method includes passive mode, semi-active mode and active mode. Under the condition of good road condition, the linear motor and the equivalent hydraulicdamper of the device of the invention recover vibration energy together; When the road surface is poor, the suspension vibration is attenuated by the linear motor together with the equivalent hydraulic damper, and the vibration energy is recovered by the equivalent hydraulic damper, so the self-energy supply can be realized.

Description

technical field [0001] The invention relates to a self-powered hybrid electromagnetic suspension and a control method thereof, which belong to the technical field of automobile suspension. Background technique [0002] In recent years, with the increasingly serious problems of environmental pollution and energy shortage, it is imperative to save energy and reduce emissions in the automotive industry. According to reliable statistics, vehicle vibration energy loss accounts for 17.2% of vehicle energy loss. For this reason, domestic and foreign experts and scholars have focused their research on vehicle vibration energy recovery. The traditional passive suspension dissipates this part of energy in the form of heat through the frictional movement of the hydraulic damper, thereby attenuating vibration and improving the ride comfort of the vehicle. Although semi-active suspensions and active suspensions have improved vibration reduction performance compared with passive suspensi...
