Abstract
The invention discloses a natural gas cylinder end support assembly. The natural gas cylinder end support assembly comprises a left thread sleeve which is connected to an outer thread at the left end of a gas cylinder in a threaded and screwed mode and a right thread sleeve which is connected to an outer thread at the right end of the gas cylinder in a threaded and screwed mode; the thread screwing direction of the left thread sleeve is opposite to that of the right thread sleeve; a left support and a flange are installed on the left thread sleeve in a sleeved mode, and the left thread sleeve, the left support and the flange are fixed together through fastening parts; a right support is installed on the right thread sleeve in a sleeved mode, and the right thread sleeve and the right support are fixed together through fastening parts; elastic buffer components are arranged between the left thread sleeve and the left support and/or the flange and the left support. By means of the natural gas cylinder end support assembly, the problems that stringing and twisting cannot be prevented simultaneously by means of pipe clamp type end support, and a beam clamp and a check ring need to be arranged are solved. Meanwhile, flexible allowance is added in the axial direction of the gas cylinder, clearance hinge does not exist on a force transmission structure, a fatigue load, caused by heat expansion and cold contraction, between the gas cylinder and a support is reduced, and the problem that the shear-bearing capacity of bolts is poor is solved.
Description
Technical field
The present invention relates to a kind of natural gas cylinder end supporting component, belong to natural gas used for automobile gas cylinder and installing area is installed.
Background technology
Natural fuels is a kind of widely used new cleaning fuel, in the market of manned vehicle, bus and commercial vehicle/comm..vehicle, share improves gradually in recent years, compared with using the vehicle of diesel oil, gasoline, with the obvious advantage in reduction pollutants, carbon emission and scrap pollution.
As a kind of energy storage component important in natural gas-powered car, the installing mechanism performance of compressed natural gas cylinder is essential to the safety of car load, reliability, economic index.
Compressed natural gas cylinder end supporting component is by horizontal for the vehicle compressed natural gas cylinder a kind of machine elements being arranged on vehicle chassis, for safety, the lightweight index reliably realizing gas cylinder installation component, develop this new type of compression natural gas cylinder end supporting component.
Summary of the invention
The present invention aims to provide a kind of natural gas cylinder end supporting component, this supporting component changes the method that existing anti-vibration and anti-twisting are realized by two parts, and integrate two kinds of functions, solve the support of pipe clamp type end to realize anti-string simultaneously, prevent turning round, the problem of anchor ear and back-up ring must be added.Meanwhile, gas cylinder axially adds flexible surplus, and force transferring structure gapless is hinged, reduces the fatigue load by generation of expanding with heat and contract with cold between gas cylinder and support, solves the problem of bolt resistance to shear difference.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of natural gas cylinder end supporting component, its constructional feature is, comprises threaded engagement and is connected to left swivel nut on gas cylinder left end outside thread and threaded engagement and is connected to right swivel nut on gas cylinder right-hand member outside thread; The thread rotary orientation of described left swivel nut and right swivel nut is contrary; Described left swivel nut is set with left socle and flange, and by fastener, left swivel nut, left socle and flange is fixed together; Described right swivel nut is set with right support, and by fastener, right swivel nut and right support is fixed together; Between described left swivel nut and left socle and/or be provided with elastic buffer component between flange and left socle.
According to embodiments of the invention, further optimization can also be done to the present invention, below for optimizing the rear technical scheme formed:
Preferably, described elastic buffer component is rubber pad, can absorb gas cylinder better and stretch, realize seamless connectivity.
Preferably, described fastener is articulation hole bolt with holes, fluted nut and spring cotter.
Above structure, the present invention screws fixed air bottle two ends by the contrary two pieces swivel nut of rotation direction and bottle mouth of gas cylinder outside thread, can realize axially, circumference location simultaneously, meets and supports requirement.Front end swivel nut and support are rigidly connected simultaneously, fill out between tail end swivel nut and support and put rubber pad, swivel nut and support use articulation hole bolt with holes to fix, effectively can absorb gas cylinder to stretch, realize the structure of seamless connectivity, thus thoroughly solve pipe clamp type end and support and cannot realize anti-string, the anti-problem turned round simultaneously, solve between gas cylinder and support by the shock problem produced that expands with heat and contract with cold simultaneously.
Compared with prior art, the invention has the beneficial effects as follows:
1, simplify the supporting construction preventing vibration, twisting, reduce supporting construction redundancy quality.
2, avoid gas cylinder pressurized excessive, improve the anti-ability of cutting of attaching parts, ensure that the safety that supporting construction reliability and gas cylinder use.
, reliably achieve the lightweight index of gas cylinder installation component 3, safely.
Below in conjunction with drawings and Examples, the present invention is further elaborated.

Detailed description of the invention
A kind of natural gas cylinder end supporting component, as in Figure 3-5, comprises threaded engagement and is connected to left swivel nut 11 on gas cylinder 1 left end outside thread and threaded engagement and is connected to right swivel nut 9 on gas cylinder 1 right-hand member outside thread; The thread rotary orientation of described left swivel nut 11 and right swivel nut 9 is contrary; Described left swivel nut 11 is set with left socle 2 and flange 5, and by fastener, left swivel nut 11, left socle 2 and flange 5 is fixed together; Described right swivel nut 9 is set with right support 3, and by fastener, right swivel nut 9 and right support 3 is fixed together; Between described left swivel nut 11 and left socle 2, between flange 5 and left socle 2, be provided with rubber pad 4.Described fastener is articulation hole bolt 10 with holes, fluted nut 7 and spring cotter 8.
During assembling, right swivel nut 9, left swivel nut 11 are screwed with gas cylinder 1 two ends outside thread respectively, articulation hole bolt 10 with holes is successively through after right swivel nut 9, right support 3, plain cushion 6, screw with fluted nut 7 and tighten, then spring cotter 8 is inserted articulation hole bolt 10 pin-and-hole with holes and bending, articulation hole bolt 12 with holes is successively through after left swivel nut 11, rubber pad 4, left socle 2, rubber pad 4, flange 5, screw with fluted nut 7 and tighten, then spring cotter 8 is inserted articulation hole bolt 12 pin-and-hole with holes and bending, the assembling of this gas cylinder end supporting component completes.
