Abstract
The invention provides a natural gas engine air track mounting bracket with a vibration attenuation function, comprising a bracket and an air track, wherein both ends of the air track are connected with the bracket; the bracket is arranged on a natural gas engine; both ends of the air track are connected with the bracket through a vibration attenuation unit, and the vibration attenuation unit comprises a metal polish rod, a metal screw and a rubber vibration attenuation block; one ends of the metal polish rod and the metal screw are respectively connected to two ends of the rubber vibration attenuation block but both do not pass through the rubber block, and the other ends of the metal polish rod and the metal screw are respectively exposed; the vibration attenuation unit is fixed on the bracket through the exposed end of the metal polish rod; and the exposed end of the metal screw of the vibration attenuation unit is connected with the air track and locked through a nut. The bracket can isolate the vibration of the natural gas engine through adopting the vibration attenuation unit so as to avoid transmitting the vibration to the air track of a connected component; and by adopting the scheme, the connected component can achieve the design purposes of reducing the noise, prolonging the service life, and the like without taking measures of increasing many reinforcing ribs, and the like, thus the invention can reduce the production cost and improve the competitive force of a complete vehicle.
Description
Technical field
The present invention relates to a kind of support with vibration-damping function, this support is used for the installing and fixing of component that needs are isolated gasoline engine vibration.
Background technique
Internal-combustion engine the time can produce vibration in work, if this vibration is not isolated, but is directly delivered on the component, just needs component to have good mode, avoids itself and natural gas engine to produce resonating and causes the inefficacy of component.
At present for the motor that uses rock gas; What the installation of its gas rail was mainly adopted is to install and fix with the rigidly connected mode of support; In order to make gas rail and mounting bracket reach good mode; Just need add a lot of stiffening ribs or other enhancements above that, but stiffening rib etc. receive all the restriction of space and bolt position often to be difficult to accomplish desirable state, and too much stiffening rib etc. makes also colleague's product appearance of the cost increase of process aspect also become untidy; The product aesthetic property is had a greatly reduced quality, and the sale of product is had a negative impact.
The patent No. is that the patent document of ZL 200520142743.9 discloses a kind of suction tude shock-reducing rack module; This shock-reducing rack module adopts damper unit rack-mount through lining and bolt, and this this mode structure is complicated, and component are many; Cause assembling complicated; Be unfavorable for producing in batches, and cost is higher, is unfavorable for being generalized on other vibration damping structure using.
Summary of the invention
The objective of the invention is to the problem to the existing technology existence, a kind of natural gas engine air track mounting bracket with vibration-damping function is provided, this support has simple in structure, and assembling is easy, and manufacturing efficiency is high and with low cost, is fit to the advantage of production in enormous quantities.
For solving the problems of the technologies described above, the technological scheme that the present invention adopted is:
A kind of natural gas engine air track mounting bracket with vibration-damping function, it comprises support and air-rail, and the two ends of said gas rail are connected with support, and support is installed on the natural gas engine;
It is characterized in that: the two ends of said gas rail are connected with support through damper unit; Said damper unit is made up of metal polished rod, metal screw and rubber damping piece; One end of metal polished rod and metal screw is connected to the two ends of rubber damping piece; But all do not run through block rubber, the other end of metal polished rod and metal screw all exposes respectively; Said damper unit is fixed on the support through metal polished rod bared end, and the metal screw bared end of damper unit then is connected with the gas rail, and through nut locking.
Said rubber damping piece preferably adopts cylindrical body, and metal polished rod and metal screw are imbedded cylindrical two ends respectively.
The advantage of this support is: the damper unit on it can be isolated the vibration of natural gas engine; Avoid transferring vibrations on the connected component gas rail; Adopt this scheme connected component not reach purpose of design such as noise and life-span with regard to not increasing measures such as a lot of stiffening ribs; Therefore reduce cost of production, improved the car load competitive ability.

Embodiment
Specify structure of the present invention below in conjunction with accompanying drawing:
Referring to Fig. 1, this natural gas engine air track mounting bracket comprises support 1 gentle rail 4, and the two ends of said gas rail 4 are connected with support 1 through damper unit 2.
Referring to Fig. 2, said support 1 is a long strip, and there is mounting hole 41 at its two ends, is respectively applied for to be installed on the natural gas engine and installation damper unit 2.
Like Fig. 3 and shown in Figure 4; Damper unit is made up of metal polished rod 21, metal screw 22 and rubber damping piece 23; Rubber damping piece 23 is a cylindrical body; One end of metal polished rod 21 and metal screw 22 is imbedded the two ends of rubber damping piece 23 respectively, but does not all run through rubber damping piece 23, and the other end of metal polished rod 21 and metal screw 22 all exposes respectively; Metal polished rod 21 and metal screw 22 are embedded in an end of rubber damping piece will be at a distance of certain distance; To guarantee that rubber is lined with enough length and comes attenuation vibration, metal polished rod 21 can bear certain moment of torsion and pulling capacity with metal screw 22 and being connected of rubber damping piece 23, with guarantee damper unit in use metal polished rod 21 can not become flexible even come off with metal screw 22.
During installation, the metal polished rod 21 on the damper unit 2 passed the mounting hole 41 on the support 1 after, adopt welding or bolt connecting mode to be fixed on the support 1.Damper unit 2 connects the support that the back forms the band vibration damping structure with support 1, will be fixed on the natural gas engine with the support of vibration damping structure through mounting hole other on the support 1 41 again.At last metal screw on the damper unit 2 22 and gas rail 4 are linked together through nut 3, be about to the gas rail and be fixed on the support 1.
