Description
(1) technical field:
The utility model relates to automobile-used auxiliary mechanism, is specially a kind of vehicle CNG gas cylinder auxiliary positioning support.
(2) background technology:
When vehicle CNG (compression natural gas) gas cylinder normally works, pressure of the inside of a bottle can reach 20MPa, the imflammable gas of so high pressure to gas cylinder itself and be connected the safety of the position such as joint, valve, pepeline fittings of gas cylinder fixing require quite high.At present in other manufacturer, what have pays little attention to vehicle CNG gas cylinder auxiliary positioning, does not arrange on the forward and backward both sides of gas cylinder the complementary locating formations preventing gas cylinder to be shifted; Although what have is provided with anti-displacement member, its complex structure cost is high, Assembly &Disassembly difficulty, anti-displacement weak effect.
If do not arrange at the forward and backward two ends of gas cylinder the complementary locating formations preventing the forward and backward displacement of gas cylinder, will there is huge potential safety hazard in vehicle:
1, each gas cylinder comprises deadweight and can reach 105Kg after aerating, the friction force that gas cylinder provides by installation gas cylinder main support and band thereof completely prevents displacement, when the friction force that the aging distortion of thin rubber cushion between gas cylinder and band or the reason such as wet and slippery that seeps water cause is not enough, rock along with vehicle travels, will be there is forward and backward displacement in gas cylinder, consequence is hardly imaginable.
2, automobile is at turning driving or when jolting road traveling, and gas cylinder forward and backwardly can rock displacement, and iff relying on the band being contained in both sides in the middle of gas cylinder to provide resistance, band is easy to plastic deformation occurs, and situation is danger close also.
Some producers are provided with hoop complementary locating formations, be specially with iron hoop respectively gas cylinder two ends banding and to tension in the middle of gas cylinder, the shortcoming of this structure is:
1, anti-displacement DeGrain, gas cylinder likely has swing displacement, once displacement, connecting multiple pipe joints of gas cylinder will be out of shape, in bottle 20MPa high pressure under be easy to cause the safety misadventures such as gas leakage.
2, the hoop of this component and Tiebar structure complicated, the component that the left and right of each gas cylinder (CNG vehicle generally fills the gas cylinder of more than 6) fills a set of heaviness also adds many deadweights to vehicle, and add traveling gas consumption, cost of manufacture is also very high.
3, because gas cylinder is arranged compact, and hoop must be fixed on the main support of installation gas cylinder by pull bar, and the operational space of clamp nut is very little, so all very difficult when Assembly &Disassembly is safeguarded, production efficiency is low.
Therefore, the auxiliary location structure that a kind of structure is simple, safety factor is high, production efficiency is high and cost reduces is developed imperative.
(3) utility model content:
For the deficiencies in the prior art, technical problem to be solved in the utility model proposes a kind of vehicle CNG gas cylinder auxiliary positioning support that effectively can prevent the forward and backward vibration of CNG gas cylinder.
The vehicle CNG gas cylinder auxiliary positioning support that can solve the problems of the technologies described above, its technical scheme comprises limited support part, before difference corresponds to CNG gas cylinder, rear two ends, two limited support parts are arranged respectively on CNG gas cylinder base for supporting, described limited support part comprises locating plate and rubber pad, before the rear portion of described locating plate offers, a backward left side, right bar hole, (locating plate) also to be installed with CNG gas cylinder base for supporting (offering bolt perforating) by bolt and nut component and is connected, described rubber pad is adhered to the front portion of locating plate, the front end face of rubber pad is lozenges, this lozenges is the cambered surface that can contact with CNG gas cylinder end anastomosis.
In said structure, by the spacing respectively forward and backward two ends of CNG gas cylinder of former and later two limited support parts of adjustable installation, thus limit the forward and backward vibration of CNG gas cylinder on CNG gas cylinder base for supporting.
For preventing rubber pad extrusion, corresponding to the left and right side of rubber pad, left and right rib is set on locating plate.
A kind of set-up mode of described left and right rib is locating plate arranged on left and right sides flange upwards.
Enough forward and backward adjustable ranges are had, the length >=40mm of described bar hole for meeting limited support part.
The beneficial effects of the utility model:
1, the utility model vehicle CNG gas cylinder auxiliary positioning support is used for the fixing of vehicle CNG gas cylinder, can prevent the forward and backward displacement of CNG gas cylinder, and structure is simple, compact size, Assembly &Disassembly are more convenient.
2, the utility model can the friction force that causes of the aging distortion of thin rubber cushion between CNG gas cylinder and band or the reason such as wet and slippery that seeps water not enough time back and front supporting power is provided, prevent that gas cylinder is forward and backward rocks displacement; Can travel at automobile turning or when jolting road traveling, provide back and front supporting to try hard to avoid and exempting from band generation plastic deformation, prevent that CNG gas cylinder is forward and backward rocks displacement; At automobile by providing bearing force upwards during nest road surface, the main mounting bracket of CNG gas cylinder can be prevented to be subject to excessive pressure generation plastic deformation, to prevent CNG gas cylinder to be shifted downwards.
3, the utility model in the end operation adopt adjustable mode to install, can prevent the forward and backward displacement of CNG gas cylinder, can avoid again crossing location and installation adverse effect to CNG gas cylinder, locating effect is obviously, safe reliability is very high.
4, confined planes of the present utility model be can with the cambered surface of CNG gas cylinder two ends close contacting fit, so add spacing contact surface, make locating effect more obvious.
5, the utility model commonality is very high, can directly on vehicle for the CNG gas cylinder of fixing multiple state, inside and outside not co-content specification.
