Problems solved by technology

[0003] In the process of realizing the present invention, the inventor found that the prior art has at least the following problems: due to its specific structure, the sealing performance of the hydraulic mount is particularly important, and once the sealing performance cannot be guaranteed, the hydraulic mount will be reduced to ordinary pure rubber Block suspension, thus losing its excellent vibration isolation performance. At present, most of the cylindrical hydraulic mounts use riveting sealing liquid, relying on the rubber main spring and the lower diaphragm to interfere with the sealing liquid. Once the size of the rubber main spring and the lower diaphragm If there is a little out of tolerance, there will be a risk of liquid leakage, poor stability, and difficult process control

Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] see figure 1 , a fluid sealing structure of an automobile hydraulic mount, having:

[0021] The hydraulic main spring formed by the sealing connection of the skeleton 1 and the rubber main spring 2;

[0022] A rubber sheet 6, wherein the rubber sheet 6 is sealingly connected with the hydraulic main spring and forms a closed space for containing damping fluid between the two;

[0023] Such as figure 2 As shown, the rubber main spring 2 is provided with a step 21 near the end, and the end surface of the rubber sheet 6 is in contact with the step surface.

[0024] The end of the rubber main spring 2 is cylindrical, and a cavity is provided inside; the skeleton 1 is cylindrical, and the skeleton 1 is set on the end of the rubber...

Abstract

The invention discloses a vehicle hydraulic suspending seal liquid composition comprising the following elements: a hydraulic main spring formed by a frame (1) and a rubber main spring (2) connected in a seal manner; a rubber sheet (6) connected with the hydraulic main spring, and a sealed room containing a damping fluid is formed between the rubber sheet (6) and the hydraulic main spring; a step (21) arranged in a position, close to an end portion, of the rubber main spring (2). An end face of the rubber sheet (6) makes contact with a step face so as to prevent leakage liquid risk, thus greatly improving hydraulic suspending seal qualified rate; the vehicle hydraulic suspending seal liquid composition is high in stability, and the technology is easy to control.

Description

technical field [0001] The invention belongs to the technical field of liquid sealing for automobile hydraulic mounts, in particular to a liquid sealing structure for hydraulic mounts of automobiles. Background technique [0002] As people's requirements for the comfort and smoothness of cars are getting higher and higher, the suspension structure of pure rubber blocks can no longer meet the requirements, so a new type of suspension element-hydraulic suspension came into being; due to its excellent Since its inception, hydraulic mounts have been valued by major automobile companies in the world, have achieved rapid development, and have been rapidly popularized in automobiles. [0003] In the process of realizing the present invention, the inventor found that the prior art has at least the following problems: due to its specific structure, the sealing performance of the hydraulic mount is particularly important, and once the sealing performance cannot be guaranteed, the hydr...
