Abstract
The utility model relates to a vehicle chassis technical field discloses a front strut NVH keeps apart rubber pad and front strut assembly, front strut NVH keep apart the rubber pad including keep apart the face and with keep apart facial features installation department even, the installation department is used for linking borehole jack interference fit in the cover outward with the shock absorber, keeps apart face and installation department and passes through injection moulding of rubber, installation department and shock absorber link outward in the cover after the borehole jack cooperation, form airtight space. The utility model discloses simple structure, simple to operate, can reduce the noise and the vibration of transmitting to the driver's cabin, interference fit can also keep apart the breathing sound that the front strut assembly was normally worked and is produced simultaneously to dustproof effect has.
Description
Technical field
This utility model relates to vehicle chassis technology field, is specifically related to a kind of front standing pillar NVH isolation rubber blanket and front standing pillar assembly.
Background technology
NVH: noise, vibration and the english abbreviation of sound vibration roughness (Noise, Vibration, Harshness).This is the global question weighing automobile making quality, and it gives being experienced as the most directly and most surface of user vehicle.The NVH problem of vehicle is one of problem of international automobile Ye Ge great car load manufacturing enterprise and parts enterprises concern.Having statistics to show, it is that the NVH problem with vehicle has relation that car load there are about the failure problems of 1/3, and there is the R & D Cost consumption of nearly 20% in each major company in the NVH problem solving vehicle.
Front standing pillar is the indispensable parts of automobile front suspension system, and front standing pillar assembly is the big vibrations that suppression automobile conveys to vehicle body in motion, to improve comfort by bus.In currently available technology, front standing pillar assembly use major part on automobile can meet use requirement, but also has weak point, and especially front standing pillar assembly easily produces abnormal sound, is transferred to vehicle body, has a strong impact on driving impression.Existing front standing pillar external connecting sleeve only installs dust cover, it is impossible to be effectively isolated the breathing within vibration and front standing pillar, and along with client is to driving the attention experienced, isolation vibration and sound become one of top-priority problem of front standing pillar exploitation.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of front standing pillar NVH and isolates rubber blanket, the noise and vibration being transferred in driver's cabin with front standing pillar assembly can be effectively reduced, and the Breathiness that the internal normal liquid flowing of isolation vibroshock produces, improve the driving impression of client.
This utility model embodiment is adopted the technical scheme that a kind of front standing pillar NVH isolates rubber blanket, including isolation face and the installation portion that is connected with described isolation face, described installation portion is used for and vibroshock external connecting sleeve inner hole sleeve interference fit, described isolation face and installation portion are by rubber single injection-molded, after described installation portion coordinates with described vibroshock external connecting sleeve inner hole sleeve, form confined space.
Preferably, described isolation face is disc-shaped.
The beneficial effects of the utility model are:
The front standing pillar NVH that this utility model provides isolates rubber blanket, by rubber straight forming, simple in construction, can directly press-fit, easy for installation；Its installed surface and vibroshock external connecting sleeve inner hole sleeve are interference fit, and formation confined space, with front standing pillar assembly be transferred to driver's cabin noise and vibration be first transferred to this rubber blanket, noise and slight vibration produce certain decay after rubber blanket, lay equal stress on and be newly transferred to front standing pillar assembly, thus decrease noise and the vibration being transferred to driver's cabin；Interference fit can also be isolated front standing pillar assembly and normally worked the breathing produced simultaneously, and has dustproof effect.
This utility model additionally provides a kind of front standing pillar assembly, including vibration damper complement and the vibroshock external connecting sleeve being arranged on described vibration damper complement one end, being provided with NVH isolating device on vibroshock external connecting sleeve inner hole sleeve, described NVH isolating device is that above-mentioned front standing pillar NVH isolates rubber blanket.Owing to above-mentioned front standing pillar NVH isolation rubber blanket has above-mentioned technique effect, the front standing pillar assembly with above-mentioned front standing pillar NVH isolation rubber blanket also should have identical technique effect.
Accompanying drawing explanation
The structural representation of the front standing pillar NVH isolation rubber blanket that Fig. 1 provides for this utility model embodiment；
The structural representation of the front standing pillar assembly that Fig. 2 provides for this utility model embodiment.
In upper figure, the corresponding relation of reference and component names is:
1 isolation face；2 installation portions；3 vibroshock external connecting sleeve inner hole sleeves；4 vibration damper complements.
Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
Refer to Fig. 1 and Fig. 2, the front standing pillar NVH that this utility model embodiment provides isolates rubber blanket, including isolation face 1 and the installation portion 2 that is connected with isolation face 1, installation portion 2 is used for and vibroshock external connecting sleeve inner hole sleeve 3 interference fit, isolation face 1 and installation portion 2 are by rubber single injection-molded, after installation portion 2 coordinates with vibroshock external connecting sleeve inner hole sleeve 3, form confined space.
The front standing pillar NVH that this utility model provides isolates rubber blanket, by rubber straight forming, simple in construction, can directly press-fit, easy for installation；Its installed surface and vibroshock external connecting sleeve inner hole sleeve 3 are interference fit, and formation confined space, with front standing pillar assembly be transferred to driver's cabin noise and vibration be first transferred to this rubber blanket, noise and slight vibration produce certain decay after rubber blanket, lay equal stress on and be newly transferred to front standing pillar assembly, thus decrease noise and the vibration being transferred to driver's cabin；Interference fit can also be isolated front standing pillar assembly and normally worked the breathing produced simultaneously, and has dustproof effect.
In this utility model one preferred embodiment, isolation face 1 is disc-shaped, it is possible to effectiveness in vibration suppression is better achieved.
Refer to Fig. 2, this utility model additionally provides a kind of front standing pillar assembly, including vibration damper complement 4 and the vibroshock external connecting sleeve being arranged on vibration damper complement 4 one end, vibroshock external connecting sleeve inner hole sleeve 3 being provided with NVH isolating device, NVH isolating device is that above-mentioned front standing pillar NVH isolates rubber blanket.Owing to above-mentioned front standing pillar NVH isolation rubber blanket has above-mentioned technique effect, the front standing pillar assembly with above-mentioned front standing pillar NVH isolation rubber blanket also should have identical technique effect, does not repeats them here.
Principle of the present utility model and embodiment are set forth by specific case used herein, and the explanation of above example is only intended to help to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; on the premise of without departing from this utility model principle, it is also possible to this utility model is carried out some improvement and modification, these improve and modification also falls in this utility model scope of the claims.
