Magnetorheological intelligent vibration damper for minisize automobile

Abstract

The present invention discloses one kind of intelligent magnetically rheologic damper for mini car. There are air membrane and pedestal forming combined energy storing air bag inside the hole on one end of the work cylinder, non-return valve installed in the screw hole on the pedestal, magnetically rheologic material filled inside the work cylinder divided into two work cavities with the piston, annular damping passage comprising the outer wall of the piston and the inner wall of the work cylinder and connecting the two cavities in the work cylinder, top cap to seal the other end of the work cylinder, piston with exciting winding, three guide blocks of non-magnetic material on the outer surface of the piston. The present invention has less magnetic leakage, raised magnetic utilization rate, simple installation, long service life, good damping characteristic and simple and compact structure. The damper may be matched with controller for automatic regulation of damping characteristic.

AI Technical Summary

Benefits of technology

This technology reduces magnelecence (MFL), improves efficiency when used for power transmission, reducing heat generation during operation, making sure there's minimal interference between different parts inside the system without causing damage from external influences like vibrations or impacts. It also enhances durability over time thanks to various technical features including design guidelines, material selection, assembly processes, and sealing techniques.

Problems solved by technology

This patented technical solution describes various ways to control the behavior of electrically driven hydraulic suspenstance(ESH). These methods involve controlling the amount or degree at which certain parameters like pressure, velocity, and acceleration changes during operation, resulting in varying degrees of dampening on the EMS' s pistons due to their movement caused by gravity forces acting upon them. By changing this parameter based on environmental variables like loadings, speed ratios, and temperatures, the dumbbell shape of the ESM becomes shaped accordingly. To achieve optimal dampenning effects, there should have some flexibility in setting up the dumbness characteristic curve. Additionally, the patented proposals suggest adding extra components called soft iron powder into the susceptible material to enhance the deterioration process over time without compromising safe driving capabilities. Overall, the proposed solutions aim to provide efficient and comfortable ride experience while maintaining desired levels of responsiveness and sensitivity.
