Vibration isolation suspension

Abstract

The invention discloses a vibration isolation suspension. The vibration isolation suspension comprises an outer shell, a rubber lining and a chip, wherein the chip and the rubber sleeve are formed integrally; the outer shell, the rubber lining and the chip are enclosed into a first damping liquid chamber, a second damping liquid chamber and at least one flow channel; the flue channels are used for communicating the first damping liquid chamber and the second damping liquid chamber; and the first damping liquid chamber and the second damping liquid chamber are formed on two sides of the chip. According to the vibration isolation suspension, the first damping liquid chamber and the second damping liquid chamber are formed on two sides of the chip and are communicated through the flow channels, a damping liquid is exchanged between the first damping liquid chamber and the second damping liquid chamber through the flow channels when an automobile generates vibration in a twisting direction, the flow channels can only be used for guiding the damping liquid on one side of the chip to the other side only by passing through or surrounding the chip, and the fluid flows in a reciprocating way, so that vibration in the twisting direction is reduced.

Description

technical field [0001] The invention relates to an automobile, in particular to a vibration isolation mount for the automobile. Background technique [0002] As consumers have higher requirements for car ride comfort, R&D personnel have also increased requirements for the damping effect of the suspension system. This is because the car is a vibrating body with multiple degrees of freedom, and the suspension system of its powertrain is mainly used for vibration isolation, fixed limit and mitigation of the vibration transmitted to the body by the wheels and engine during operation. [0003] The existing hydraulic mount mainly needs to attenuate the vibration of the powertrain caused by the excitation of the road surface or the fluctuation of the output torque. figure 1 An analysis diagram of the existing vehicle vibration is given, where the X direction represents the bumping vibration along the gravity direction, the Y direction represents the vibration along the wheel axis ...
