Abstract

The invention relates to a magnetorheological TOP MOUNT structure for an automotive suspension with adjustable rigidity. The magnetorheological TOP MOUNT structure comprises an upper connecting plate and a lower connecting plate, and is characterized in that a sleeve is arranged in a cavity between the upper connecting plate and the lower connecting plate, an upper guide base and a lower guide base are arranged at the upper end and the lower end of the sleeve respectively, the cavity enclosed by the sleeve, the upper guide base and the lower guide base is injected with magnetorheological liquid, a piston rod penetrates through the upper connecting plate, the lower connecting plate, the upper guide base and the lower guide base, and a valve body is fixedly arranged at the position, located in the sleeve, of the piston rod; the outer cylinder surface of the sleeve is provided with an electromagnetic coil, and the electromagnetic coil controls the viscosity and fluidity of the magnetorheological liquid in the sleeve according to the up and down motion of the piston rod. The magnetorheological TOP MOUNT structure realizes the adjustability of TOP MOUNT rigidity, is ingenious, convenient to use, good in damping effect and long in service life, and guarantees the stable operation of the piston rod.

Description

technical field [0001] The invention belongs to the technical field of automobile chassis, in particular to a magnetorheological TOMPOUNT structure for automobile suspension with adjustable rigidity. Background technique [0002] In the automobile suspension structure, the strut TOP MOUNT (that is, the installation connection structure at the upper end of the strut) is used to connect the shock absorber and the spring to the body. The role of TOP MOUNT is: [0003] 1. Bear the load; [0004] 2. Attenuate some high-frequency vibrations with frequencies above 30HZ that are not filtered out by the tire, shock absorber & spring system; [0005] 3. Control body roll. [0006] This requires the TOP MOUNT to have a small stiffness when the vehicle is moving with low amplitude and high frequency, and have a large stiffness when the vehicle is moving with high amplitude and low frequency. But the existing TOP MOUNT is a single-stage rubber block structure, such as figure 1 As sh...
