Problems solved by technology

[0010] The technical problem to be solved by the present invention is to overcome the poor decoupling efficiency of the vibration isolation mount in the prior art because the decoupling membrane has no annular slot and can only be integrally formed or directly attached to the bottom wall of the flow channel skeleton The defect is to provide a decoupling membrane with an annular slot, a decoupling membrane skeleton containing the decoupling membrane, and a vibration isolation mount containing the decoupling membrane skeleton

Embodiment 1

[0036] The vibration isolation mount of this embodiment has many identical parts with the existing vibration isolation mount, and these identical parts will not be repeated here. Such as Figure 3-4 As shown, the difference between this embodiment and the existing vibration isolation mount is that the decoupling membrane 61 is cylindrical in shape, and the side of the cylinder includes an annular slot 612, and the decoupling membrane 61 has a smooth surface 611 . Such as image 3 As shown, an annular connecting piece 60 is welded on the inner wall of the runner frame 4 , and the inner edge of the connecting piece 60 is snapped into the annular locking groove 612 of the decoupling membrane 61 . Since the decoupling film 61 can be snapped onto the bottom wall of the flow channel framework 4 and form a preset gap on the bottom surface of the flow channel framework 4, the curvature of the deformation of the decoupling film 61 can be greater than that of the flow channel framewor...

Embodiment 2

[0038] The vibration isolation mount of this embodiment has many identical parts with the vibration isolation mount of Embodiment 1, and these identical parts will not be repeated here. Such as Figure 5 As shown, the main difference between the vibration isolation mount of this embodiment and Embodiment 1 is that four hemispherical bumps 6111 are arranged on the cylindrical surface 611 . A circular through hole 6112 is also disposed on the cylindrical surface 611 . In actual manufacturing, the shape of these bumps can also be columnar, tetrahedral or ellipsoidal, and the specific number is not limited to four.

[0039] By arranging these bumps, the decoupling membrane 61 can contact and break away from the bottom wall of the flow channel skeleton 4 through the hemispherical bumps 6111 during vibration, thus avoiding the smooth surface 611 of the decoupling membrane 61, and the vibration The whole body is attached to the bottom wall of the skeleton, and it is difficult to de...

Embodiment 3

[0041] The vibration isolation mount of this embodiment and the vibration isolation mount of Embodiment 2 have many identical parts, and these identical parts will not be repeated here. Such as Figure 6-8As shown, the main difference between the vibration isolation mount of this embodiment and Embodiment 2 is that: the vibration isolation mount of this embodiment also includes a decoupling membrane skeleton 6, and the decoupling membrane skeleton 6 includes an annular top surface 64 , an annular side 63 and an annular bottom 62, the annular side 63 is provided with a first runner port 632, as Figure 8 As shown, the outer surface of the annular side 63 is provided with a positioning groove 631 (from the inner surface of the annular side 63, it is convex, as Figure 7 As shown), the inner edge of the annular top surface 64 is provided with a decoupling film 61 as described above, the inner edge is formed with a columnar connection hole 641, and the decoupling film 61 is a mat...

Abstract

The invention discloses a decoupling film in a cylinder shape, the side of the cylinder shape comprises an annular clamping trough. The invention discloses a decoupling film skeleton and a vibration isolation suspension. The annular clamping trough can be arranged on the decoupling film, and the decoupling film can be buckled on the bottom wall of a runner skeleton and forms a predetermined gap on the runner skeleton so as to sufficiently play the decoupling efficiency. The invention also provides the decoupling film skeleton, the usage of the decoupling film skeleton is not only convenient for installing the decoupling film, but also can form the damping vibration to share the energy of the vibration, thereby improving the decoupling efficiency. Furthermore, the invention also provides the vibration isolation suspension, by using the decoupling film skeleton provided by the invention, the vibration isolation suspension can prolong the life of a lining of the rubber material, sufficiently plays the efficiency of the decoupling film, and well decouples the large intermediate-frequency vibration.

Description

technical field [0001] The invention relates to an automobile, in particular to a decoupling membrane used in the automobile, a decoupling membrane skeleton containing the decoupling membrane and a vibration isolation mount containing the decoupling membrane skeleton. Background technique [0002] A car is a vibrating body with multiple degrees of freedom. 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, especially when the powertrain is in the vertical direction. The decoupling rate of the modes on . [0003] Such as Figure 1-2 As shown, the vibration isolation suspension in the prior art includes a fixing part 81, a mounting bracket 8, a housing 7, a lining 3, a core 2, a limiting groove 22, a mounting hole 21, a first A damping liquid chamber 51, a second damping liquid chamber 52, a channel frame 4, a channel 41, several decoupli...
