AI Technical Summary

Benefits of technology

In this patented technology, there was introduced an improved magnetic liquid viscosity controller (MFC) system called Magneto-Reno Dual Fluid(MRF). It solved problems such as difficulty achieving consistently high levels of pressure or resistance during different driving situations due to changes made by road surfaces over time. By utilizing MRF's unique characteristics, MFC systems were able to provide more precise and adaptable solutions than previous methods like hydraulic shock absorbers.

Problems solved by technology

The technical problem addressed by this patented technology relates to improving the responsiveness or ability of an active vibrating system (AVS) with multiple tires connected together without losing contact between them during use. This requires a special type of buffer called a dual tubular structure made up of two independent cylinders filled with liquid crystal material. By changing both pressure levels and recoverability settings at specific points along their length, the design allows for more flexible adaptation over varying operating environments while maintaining optimal energy efficiency.

Abstract

The invention discloses a separated double-cylinder magnetorheological damper. The damper comprises a first piston cylinder and a second piston cylinder which are arranged in mutual angular communication, the first piston cylinder comprises a piston inner cylinder and a piston outer cylinder which are coaxially arranged, and a magnetorheological fluid circulation channel is formed among the pistoninner cylinder, the piston outer cylinder and the second piston cylinder; a piston rod assembly capable of reciprocating in the axial direction of the piston inner cylinder is arranged in the pistoninner cylinder, a first magnetorheological fluid adjusting mechanism is fixedly arranged at the bottom of the piston inner cylinder, and a second magnetorheological fluid adjusting mechanism is arranged in the second piston cylinder; and the first magnetorheological fluid adjusting mechanism and the second magnetorheological fluid adjusting mechanism are provided with magnetorheological fluid channels capable of supplying magnetorheological fluid to form different flow circulation loops. According to the technical scheme, the damper solves the problems that a passive vibration damping device is difficult to adaptively adjust the limit of the damping force according to working conditions and the control algorithm of the magnetorheological damper is complex, so that independent adjustment ofthe compression force and the restoring force of the magnetorheological damper is realized.
