A Double Inertia Channel Engine Hydraulic Mount Structure

Abstract

The invention discloses an engine hydraulic suspension structure with dual inertial channels. The structure includes a shell, wherein the upper end of the shell is provided with a rubber main spring,a framework and a first connection bolt, the lower end of the shell is provided with a base and a second connection bolt, the shell is internally provided with an inertial channel body, and the inertial channel body is internally provided with a first inertial channel and a second inertial channel; an inlet end of the first inertial channel is arranged on the right side of the upper surface of theinertial channel body, an outlet end of the first inertial channel is arranged on the left side of the lower surface of the inertial channel body, an inlet end of the second inertial channel is located on the left of the outlet end of the first inertial channel, and the outlet end of the second inertial channel is located on the right side of the lower surface of the inertial channel body. The structure further includes a sliding support, wherein a connection port in the top of a cover plate on the left side of the sliding support covers the inlet end of the second inertial channel, a stop block is arranged on the right side of the sliding support and blocks the outlet end of the second inertial channel, the inner wall of the shell is fixedly provided with a supporting ring, and the innerwall of the right side of the supporting ring is provided with a driving mechanism for driving the sliding support to slide left and right. The structure has a good vibration reduction effect when big vibration occurs.

Description

technical field [0001] The invention relates to the field of hydraulic mounts, in particular to an engine hydraulic mount structure with double inertia channels. Background technique [0002] Automotive hydraulic mounts generally include a casing, the upper end of the casing is fixed by a rubber main spring, a connecting bolt is installed on the skeleton, another connecting bolt is installed on the base of the lower end of the casing, one of the bolts is used to connect the engine, and an inertial channel body is fixed inside the casing. The interior of the shell is divided into upper and lower parts by the inertial channel body. The inner shell is located under the inertial channel body and a bottom film is fixed. There is a decoupling plate in the middle of the inertial channel body. There is also an inertial channel in the inertial channel body. The inlet of the inertial channel The end is set on the upper surface of the inertial channel body, and the outlet end is set on...
