An electromagnetic variable suspension and its adjustment method

Abstract

The invention relates to an electromagnetic variable suspension and a regulating method thereof. The electromagnetic variable suspension comprises a sleeve and a cylinder pot, wherein the sleeve is fixedly arranged on an axle, the cylinder rod is fixedly arranged on a vehicle frame, a spring for supporting the vehicle frame is connected between the axle and the vehicle frame, the lower end of the cylinder rod extends into the sleeve, in addition, the lower end of the cylinder rod and the sleeve are glidingly matched, a first iron core coil circuit used for downwards attracting or upwards repelling the cylinder rod is arranged in the sleeve, the lower end of a first iron core of the first iron core coil circuit is fixedly arranged on the axle, the upper end of the first iron core of the first iron core coil circuit is opposite to the lower end of the cylinder rod, and the inner wall of the upper end of the sleeve is provided with a position limiting electromagnetic valve used for locking the cylinder rod. The electromagnetic variable suspension and the regulating method have the advantages that the electromagnetic control with lower cost is adopted, the response speed is high, the control is sensitive and accurate, the height of the suspension can be automatically changed according to the signal collection of the sensor, the requirements of high ground leaving gap in mountain road running and low ground leaving gap in high speed running on flat roads can be met, and the electromagnetic variable suspension and the regulating method conform to the contemporary automobile development trends.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an electromagnetic variable suspension and an adjusting method thereof. Background technique [0002] Under different road conditions, there are different requirements for the ground clearance of the car: in high-speed road conditions, the aerodynamics of the car needs to be considered. At this time, if the ground clearance of the body can be reduced, the car will be more stable, and the achieved The speed of the vehicle is greater; when on a potholed road, the passability of the car needs to be considered, and the ground clearance of the car must be increased at this time. [0003] For passive suspension and semi-active suspension, it is impossible to automatically adjust the height of the vehicle body, which cannot meet the requirements for the height of the vehicle body under different working conditions, and also has different degrees of adverse effects on the comfort of ...
