Abstract

The invention discloses an automobile suspension bushing and an automobile. The automobile suspension bushing comprises an inner sleeve, a rubber main body, an outer sleeve and a mounting bracket, wherein two hydraulic cavities filled with magnetorheological fluid are formed in the rubber main body; an upper flow channel and a lower flow channel are arranged on the rubber main body at an interval,and the upper flow channel and the lower flow channel are respectively communicated with the two hydraulic cavities; the magnetorheological fluid can flow between the two hydraulic cavities; and an electromagnetic coil capable of providing a variable magnetic field for the magnetorheological fluid is arranged on the outer sleeve. According to the automobile suspension bushing and the automobile,the damping performance of the automobile suspension bushing can be actively controlled and adjusted in real time, so that under different automobile conditions, the damping characteristic more suitable for the automobile conditions can be obtained through control of the trip computer and the current adjusting unit, and therefore better whole automobile controllability and comfort performance areprovided, and driving quality is improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic bushings, in particular to an automobile suspension bushing and an automobile. Background technique [0002] Automobile suspension bushing parts are usually assembled on chassis components such as control arms, connecting rods, steering knuckles, and subframes of automobile suspensions. As the connection unit of the structural parts of the automobile chassis, the automobile suspension bushing can realize the relative movement function between the structural parts, and realize the vibration isolation and absorption functions, etc. [0003] At present, the electronic control and intelligence of automobiles have become the new competition focus of OEMs, and customers have higher requirements for automobile driving experience and sense of technology. Automobile suspension bushes affect vehicle handling stability and ride comfort. [0004] The automobile suspension bushing in the prior art can only...
