Description
Technical field
The utility model relates to a kind of cng automobile natural gas filtering apparatus, particularly a kind of mounting bracket of natural gas filter.
Background technology
CNG(Compressed Natural Gas) automobile refers to using compression natural gas and substitutes regular price gasoline or the diesel oil automobile as motor vehicle fuel.The natural fuels formed primarily of methane is adopted to be similar in car in the gas cylinder of fuel tank, as motor vehicle fuel at the stored under pressure of about 25Mpa in CNG automobile (being also called gas combustion automobile).Main processes by 0.3 ~ 0.8Mpa low pressure natural gas, boosts to 25Mpa through natural gas compressor at CNG automobile station, is controlled by sequence control dish, by high, medium and low voltage ordered storage to gas storage cylinder group, then is annotated to automobile steel cylinder by CNG filling machine.And automobile steel bottle height calm the anger again through pressure purger decompression after through fuel gas mixture to driving engine air feed.
Natural fuels burning-point, up to more than 650 degree, is not easily lighted; Density is low is 0.48, is difficult to be formed meet fiery burning concentration; Antiknock property is good up to 130 anti-detonating qualitys, and explosive limits is only 5-15%, thus safer compared with gasoline.Automobile-used air bottle is all through burning, exploding, fall, use after the test passes such as gunslinging.China and foreign countries' Natural Gas Motor Vehicle over 60 years, never occurred because of gas explosion, burning and cause the example of car accident.Due to above-mentioned advantage, current CNG automobile and development and application are more and more subject to people and pay attention to, and at present, have the area of gas distributing system condition both at home and abroad all to develop CNG automobile.
In CNG automobile, natural fuels is before entering driving engine, all needs to filter through natural gas filter, to remove the foreign material that may contain in natural fuels, guarantees engine health work.At present, existing natural gas filter generally all adopts the filter of tubular to filter, and such as, a kind of filter of gas combustion automobile disclosed in China's number of patent application 200520020188.2, namely have employed this kind of typical structure.This cylindrical filter when mounted, generally adopt the mounting structure of locking hood type to carry out installation to fix, such as, namely a kind of Novel gas filter mounting bracket disclosed in China's number of patent application 201220260334.9 have employed this structure, it comprises integrative-structure and orthogonal adapter plate and adapter plate, adapter plate is fixed on motor body, and adapter plate is provided with gas filter clip and warm wind water pipe passage, and adapter plate and adapter plate are equipped with stamping forming reinforced rib.This structure is comparatively simply, fixing comparatively reliable, but still it is comparatively inconvenient to there is installation, installs less stable, easily loosens the problems such as rear generation abnormal sound.
In order to solve the problem, applicant considers to carry out damping, buffering at the outer sheathed elastic buffering pad of cartridge type filter, and then adopt a mounting bracket with fixed part and installation portion to install, wherein fixed part is arranged bolt hole for being fixedly connected with vehicle frame, installation portion have one for the installation cavity of elastic buffering pad and inner filtration cylinder thereof is installed and one enter the card interface of installation cavity for elastic buffering pad and inner filtration wound packages thereof, for the installation of cartridge type filter and elastic buffering pad.Good elastic buffer effect can be had like this and install more for convenience.
But how the wherein concrete structure of mounting bracket, should design, can have structure simple, cartridge type filter and elastic buffering pad installation snap in convenient and swift, the features such as installation fixed effect is reliable and stable, and self Joint strenght is reliable and stable, become the problem needing to consider to solve.
Utility model content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is: how to provide a kind of structure simple, cartridge type filter and elastic buffering pad installation snap in convenient and swift, install fixed effect reliable and stable, the natural gas filter mounting bracket that self Joint strenght is reliable and stable.
In order to solve the problems of the technologies described above, the utility model have employed following technical scheme:
A kind of natural gas filter mounting bracket, described mounting bracket has a fixed part and an installation portion, it is characterized in that, described fixed part is provided with bolt hole and for being connected with vehicle frame, the fixed part of described mounting bracket be U-shaped like structure and spiro keyhole position in U-shaped structural base position, the flap that the both sides of described fixed part U-shaped structure extend formation two transversal surfaces curved to outer camber line obtains described installation portion, the inner chamber that two flaps surround and elastic buffering pad outer circumference surface coupling are configured for the installation cavity installing cushion rubber and inner filtration cylinder thereof, the card interface entering installation cavity for elastic buffering pad and inner filtration wound packages thereof is formed between the seamed edge of described two flaps away from fixed part.
Like this, mounting support structure is simple, takes up room little, and makes to install the fast easier for installation of cushion rubber and inner filtration cylinder thereof.
As optimization, the surface of internal cavity that described flap surrounds has been disposed radially ledge structure.Like this, then by corresponding vertically for elastic buffering pad, one section of reducer is set to form step vertically at its outside face, both making during assembling, can fits better tight, prevent from moving axially, improve and install reliably.
Further, described flap two ends along its length have the catch edge that inwardly protruding is formed, and catch edge is used for the edges at two ends position that elastic buffering pad and inner filtration cylinder thereof are lived in clamping.
Like this, can prevent from further moving axially equally, improve installation reliability.
Further, described flap forms flange away from the seamed edge neck-out of fixed part.Like this, more can be beneficial to the installation of installing cushion rubber and inner filtration cylinder thereof to snap in.
Further, the bottom integrated of described fixed part U-shaped structure is tabular, and described spiro keyhole position is in intermediate position, and bolt hole two edge is upwards heaved perpendicular to the direction of U-shaped structure both sides and is formed with twice reinforced rib.
Like this, adopt minimum consumptive material at utmost to improve structural strength around bolt hole, improve and connection reliability is installed.
Further, the bottom of described fixed part U-shaped structure is also provided with along an end margin of cartridge type filter axis the locating piece being bent downwardly and extending to form.When can make like this to install, conveniently first position by locating piece.
In sum, it is simple that the utility model has structure, and cartridge type filter and elastic buffering pad installation snap in convenient and swift, install fixed effect reliable and stable, the advantages such as self Joint strenght is reliable and stable.
