A new energy vehicle active suspension vibration isolation rubber body structure

Abstract

The present invention relates to the technical field of active suspension, and discloses a vibration isolation rubber body structure of an active suspension of a new energy vehicle, comprising a tubular frame, a disc-shaped frame is arranged in the middle of the tubular frame, a rubber main spring is arranged outside the assembly of the tubular frame and the disc-shaped frame, a hydraulic cavity is arranged in the middle of the rubber main spring, a plurality of spacers are arranged inside the hydraulic cavity, and the hydraulic cavity is divided into a plurality of annular piston cavities by the spacers, and a vibration diaphragm assembly is arranged in each annular piston cavity. The hydraulic oil can be sucked through the oil filling pipe and the oil filling pipe to reduce the hydraulic pressure inside the hydraulic cavity, so that the strength of the middle part of the rubber main spring is lower than the strength of its surroundings, so that the deformation of the rubber main spring is mainly concentrated in the middle part, and the vibration of the tubular frame and the disc-shaped frame assembly is suppressed by the hydraulic pressure and the resistance of the hydraulic oil flow, so as to avoid the overall hardening of the rubber main spring under high-frequency vibration, and ensure the damping effect of the rubber main spring under high-frequency vibration.
