Abstract
The utility model relates to an engine air-rail bracket with a strengthening structure. The whole bracket is in an L-shape, the bottom surface of the bracket is connected with an engine cylinder coverthrough the screw bolt, and the vertical surface of the bracket is connected with the air-rail through the screw bolt. Both ends of the bracket are respectively provided with a strengthening rib which plays a strengthening role, and the strengthening ribs and the bottom surface and the vertical surface of the bracket form a stable triangle, which make the whole bracket have strong earthquake resistance, and the strengthening effect is obvious.
Description
Technical field
The utility model belongs to technical field of engines, is specifically related to a kind of engine air track support with reinforced structure.
Background technique
For using CNG (compressed natural gas) to make the motor of fuel, the function of air valve is that fuel gas injection is burnt in air flue or firing chamber, and four air valves of many at present employings are evenly distributed on the gas rail, the gas rail is by on the facade that is bolted to " L " type gas rail support, gas rail support is fixed by bolts on the boss in the cylinder head cover outside at the two ends of its bottom surface, whole gas rail stiffness of support is very low, air valve and gas rail are suspended from the outside of the gentle rail support of cylinder head cover, and air valve is heavier, make gas rail support facade bear outwards bigger pulling force, like this, be easy to make the distortion that is stretched because of turning up of gas rail support, in the normal engine speed scope, very easily produce resonance and cause gas rail support fracture failure.
Summary of the invention
The purpose of this utility model is at existing mounting structure to provide a kind of engine air track support of optimizing improved band reinforced structure in the deficiency aspect the rigidity Design.
The technical solution of the utility model is as follows:
A kind of engine air track support with reinforced structure, gas rail support is a long strip, the cross section is L-shaped, its facade two ends respectively are provided with a bolt mounting holes, a nut is respectively welded in relevant position at bolt hole, the two ends, bottom surface respectively are provided with a bolt mounting holes, and a side corresponding with gas rail position is provided with the boss that gas rail support is used is installed on cylinder head cover, and gas rail support is fixed by bolts on the cylinder head cover by the bolt mounting holes of its bottom surface and the boss on the cylinder head cover.Be respectively arranged with the stiffening rib of reinforing function together at gas rail support two ends, stiffening rib and constitutes stable triangle with the bottom surface of support and facade between bolt mounting holes and nut.
Owing to respectively be provided with a stiffening rib at the two ends of support, constitute stable triangle with the facade and the bottom surface of rack body, improved the rigidity of whole gas rail support, solved gas rail support and turned up and the distortion that is stretched easily, easily produced resonance and cause the problem of fracture failure.
