The automobile power assembly supporting suspends
Technical field
The utility model belongs to the air suspending field, particularly relates to a kind of automobile power assembly supporting and suspends.
Background technique
The power assembly suspension system vibration is the part of vehicle complete vehicle vibration, it all has bigger influence to body vibrations and car room noise level, the quality of design on Mounting System will directly have influence on the vibration noise level of car load, be the key factor that influences riding comfort.The main vibration source of automobile power assembly suspension system is reciprocal unbalance inertia force and the torque fluctuations that himself produces in the working procedure, automobile travels on various road surfaces in addition, because the vibrational excitation that road roughness causes also can exert an influence with power assembly suspension system.Therefore the main effect of automobile power assembly suspension system can be divided into two aspects, reduces vibration and the displacement of control power assembly that power assembly passes to vehicle body that is:.
There is following shortcoming in hydraulic mount at present: 1. owing to be full of the ethylene glycol mixture body in the liquid chamber up and down, generally work under bad working environments and suspend, be easy to generate leak of liquid, the hydraulic characteristic that causes suspending lost efficacy; 2. though its dynamic performance of hydraulic mount satisfies the requirement of car load NVH characteristic to a certain extent, because its comparatively expensive cost makes it be difficult to promote in general car field; 3. the leak of liquid in the hydraulic mount is easy to generate pollution to environment; 4. hydraulic mount needs dry type or wet type can, can increase product cost undoubtedly.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of automobile power assembly supporting and suspends, to solve NVH performance requirements such as vibration insulation and noise reduction, vibration reduction and cushioning.
The technological scheme that its technical problem that solves the utility model adopts is: provide a kind of automobile power assembly supporting to suspend, by top sulfuration part, bottom sulfuration part, the rubber diaphragm, the decoupling zero film, decoupling zero membrane bone frame, fuse, skeleton, bottom, outer cover and mounting bracket are formed, and described top sulfuration part is positioned at automobile power assembly and supports the top that suspends, and described bottom sulfuration part is positioned at automobile power assembly and supports the bottom that suspends, described decoupling zero film is positioned at rubber diaphragm below, described decoupling zero membrane bone chord position is in decoupling zero film below, and described outer cover shade is in sulfuration part outside, top, and described bottom shade is riveted in sulfuration part outside, bottom and with outer cover.
Described top sulfuration part is made up of fuse, rubber spring and mounting bracket, described fuse is positioned at automobile power assembly supporting center of suspension position, described rubber spring is surrounded on fuse and contacts with fuse, and described mounting bracket is positioned at the rubber spring outside and is surrounded on rubber spring.
Described bottom sulfuration part is made up of outer skeleton, rubber diaphragm and skeleton, described skeleton is positioned at suspend bottom and be surrounded on bolt of automobile power assembly supporting, described rubber diaphragm is positioned at the skeleton outside and is surrounded on skeleton, and described dermoskeleton chord position is in the rubber diaphragm outside and be surrounded on the rubber diaphragm.
Described upper chamber is by the rubber diaphragm, the decoupling zero film, and decoupling zero membrane bone frame, fuse and top sulfuration part are formed.
Described fuse and skeleton, bolt and decoupling zero membrane bone frame seal by O type circle one and O type circle two respectively.
Described lower chambers is made up of bottom and mounting bracket, and described mounting bracket is connected and fixed with bottom in bottom is inboard.
Described inertia channel is between upper chamber and lower chambers.
Beneficial effect
Advantage of the present utility model is as follows:
(1) has dynamic performance with similar low frequency large-amplitude vibration of hydraulic mount and high frequency small amplitude motion, can satisfy the NVH performance requirement such as vibration insulation and noise reduction, vibration reduction and cushioning of automobile power assembly suspension system;
(2) the inertia channel structure of inertia channel in the rubber diaphragm and hydraulic mount is simpler, and adjustability is better;
(3) bolt and fuse adopt the assembling mode of riveting, improve the manufacturing efficiency of reliability of products and part;
(4) replace liquid (ethylene glycol) that cost is reduced greatly with air and manufacturing process more simple.
