Description

Technical Field

[0002] The hydraulic mount assembly is an elastic element that connects the powertrain and chassis and plays a supporting role in the automotive powertrain. The existing hydraulic mount assembly is generally installed under the vehicle chassis. The hydraulic mount assembly generally achieves a shock-absorbing effect on the powertrain through the flow of internal hydraulic oil. When the vehicle is driving, the hydraulic mount assembly will frequently move up and down, and the internal parts of the hydraulic mount assembly will rub against each other and easily generate heat. Therefore, heat dissipation holes are generally provided under the hydraulic mount assembly.

[0003] The existing application number is: CN201510661716.0 The present invention relates to a hydraulic mount having an upper liquid chamber and a lower liquid chamber, the upper liquid chamber being defined above a nozzle plate installed therein, the lower liquid chamber being defined below the nozzle plate, and the hydraulic mount being configured so that the hydraulic liquid filled therein flows to the upper liquid chamber and the lower liquid chamber through a path defined in the nozzle plate, the hydraulic mount may include a disc-shaped diaphragm and a spring having an annular shape to which the edge of the diaphragm is fitted, and the spring is installed in a mounting recess formed in the nozzle plate, wherein the spring may include: a body portion to which the diaphragm is fastened; an upper annular portion, which is arranged above the body portion; and a lower annular portion, which is arranged below the body portion. The hydraulic mount according to the present invention converts the vertical vibration of the diaphragm into a rotational force to reduce or prevent the generation of a rattling noise.

[0004] Based on the above, the internal leather cup of the existing hydraulic suspension assembly is generally set at the lower end of the hydraulic suspension assembly.

Since the leather cup is mostly made of rubber material, external mud and dust will accelerate the aging of the leather cup and affect the service life of the entire hydraulic suspension assembly.
