Abstract
The utility model relates to a novel air suspension. The novel air suspension is composed of an elastic main spring (4), a core (2), an upper chamber (a) and a lower chamber (b); the elastic main spring (4) is molded by vulcanizing the core (2) and a body bracket (5); the upper chamber (a) is an air cavity which is composed of the elastic main spring (4) and A limiting plate (6); the lower chamber (b) is an air cavity which is composed of the limiting plate (6) and a muffler plate (7); the limiting plate (6) and the muffler plate (7) are riveted and fixed through the body bracket (5); the body bracket (5) is connected with a car body; and the core (2) is connected with an engine through bolts (1). The novel air suspension disclosed by the utility model can obtain certain damping at a low frequency; and according to the novel air suspension disclosed by the utility model, airflow noise of the suspension under large-amplitude excitation is reduced efficiency, the use range of the air suspension is expanded and NVH (Noise Vibration and Harshness) performances of the whole car are improved.
Description
Technical field
The utility model relates to power assembly suspension system vibration damping field, particularly relates to a kind of novel air 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 goes 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 the transmission and the displacement of control power assembly of power assembly vibration to vehicle body that is:.
People have also carried out long-term exploration, have invented that pure glue suspends, hydraulic mount.These can both play and reduce the power assembly vibration to the transmission of vehicle body and the effect of control power assembly displacement.Because rubber mounting is applied to automobile industry with cost advantage always, but that rubber mounting can not satisfy simultaneously is low, the damping capacity requirement under the high frequency; And hydraulic mount can obtain bigger damping but thereby decoupling zero effectively reduces the frequency of dynamically hardening that suspends with the decay road excitation, under high frequency under low frequency, obtained and must use at automotive field.But rubber mounting and hydraulic mount can not find a new equinoctial point between performance and cost.Air suspending can satisfy cost can satisfy performance again, will be widely used in automobile industry.
Air suspending is through pressurized air, lets it pass through the throttle orifice in the limiting board, reaches the effect that improves damping from face.Conventional air suspending, air can produce whistle during through throttle orifice, and this will directly influence the NVH performance of car load, so there is certain narrow limitation in the use of air suspending.
Summary of the invention
The utility model technical problem to be solved provides a kind of novel air and suspends, and is used to solve the narrow limitation that air suspending uses, and makes that air suspending can obtain extensively using reliably.
The utility model solves the technological scheme that its technical problem adopted: provide a kind of novel air to suspend, comprise elasticity master spring 4, fuse 2, a of upper chamber and lower chambers b.Described elasticity master's spring 4 is that fuse 2 passes through sulfidization molding with this body support frame 5; The described a of upper chamber is the air cavity of elasticity master spring 4 and limiting board 6 compositions; Described lower chambers b is the air cavity of limiting board 6 and muffler plate 7 compositions; Described limiting board 6 connects fixing with muffler plate 7 through 5 riveted joints of this body support frame; Described body support frame 5 is connected with vehicle body; Described fuse 2 is connected with motor through bolt 1.
Novel air according to claim 1 suspends, and it is characterized in that, described a of upper chamber and lower chambers b are full of air.
Novel air according to claim 1 suspends, and it is characterized in that, described fuse 2 is to be processed by aluminium material.
Novel air according to claim 1 suspends, and it is characterized in that, described body support frame 5, position-limiting cover 3 and limiting board 6 are to be processed by metallic material.
Novel air according to claim 1 suspends, and it is characterized in that, described elasticity master's spring 4 is to be processed by rubber material.
Novel air according to claim 1 suspends, and it is characterized in that, described muffler plate 7 is to be processed by nylon material.
Beneficial effect
Owing to adopted above-mentioned technological scheme, the utility model compared with prior art has following advantage and good effect: the utility model has increased muffler plate below limiting board; The hemisphere face boss is arranged on the muffler plate, is to be used for the air that disperses to come out from throttle orifice, make that air goes out from throttle orifice after; Rush at the hemisphere face boss of muffler plate, then to around leave, reached cancellation whistle effect; So; Air suspending just can obtain using more widely, and through various tests, the utility model air suspending can satisfy the requirement of the NVH of car load.

Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiments only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
The mode of execution of the utility model relates to a kind of novel air and suspends, and is as shown in Figure 2, comprises elasticity master spring 4, fuse 2, a of upper chamber and lower chambers b.Described elasticity master's spring 4 is that fuse 2 passes through sulfidization molding with this body support frame 5; The described a of upper chamber is the air cavity of elasticity master spring 4 and limiting board 6 compositions; Described lower chambers b is the air cavity of limiting board 6 and muffler plate 7 compositions; Described limiting board 6 connects fixing with muffler plate 7 through 5 riveted joints of this body support frame.Wherein, a of upper chamber and lower chambers a are full of air, and fuse 2 is to be processed by aluminium material, and this body support frame 5, position-limiting cover 3 and limiting board 6 are to be processed by metallic material, and muffler plate is to be processed by nylon material.In use, this body support frame 5 is connected with vehicle body; Fuse 2 is connected with motor through bolt 1.
Be not difficult to find that the utility model has damping characteristic preferably under large amplitude, under little amplitude, have more excellent decoupling zero characteristic, can satisfy suspension system car load NVH characteristic requirements.Because air suspending has increased muffler plate, eliminated the whistle of air suspending under the large amplitude excitation, thereby enlarged the using scope of air.
