CN2476702Y - Integral base for bottom of engine cover and water bank cover - Google Patents

Abstract

The utility model discloses a water tank cover(1), whose framework takes an isosceles trapezoid shape and whose lateral surface takes a right trapezoid shape. Wherein, the two lower ends of the water tank cover(1) are respectively connected with the opening internal edge of a pedestal(2) with a Phi-shaped plate body so as to form an integrity. The utility model has the advantages of simple and compact structure, easy and convenient masking and mounting operations, low cost and also effective noise reduction.

Description

The all-in-one-piece pedestal of the bottom of engine hood and radiator shell

The utility model relates to the bottom and the all-in-one-piece pedestal of radiator shell of the pedestal, the especially engine hood that reduce front engine passenger vehicle internal car noise.

Bus with front engine internal car noise source is mainly from motor and radiator fan, adopt engine hood and radiator shell at present separately, the centre overlaps, the shirt rim directly contacts with the floor, though the rubber strip sealing is arranged, but, exist the slit that differs in size just to become the main leakage region of noise because the restriction of way-train cost and technological level can not fit into one with floor and radiator shell closely.

The purpose of this utility model is to reduce and to leak with the noise isolation of motor and radiator fan outside car, is by slit and junction point at leakage, the leakage of noise in car, propagates the bottom and the all-in-one-piece pedestal of radiator shell of the engine hood that is suppressed.

The purpose of this utility model is achieved in that and is under the radiator shell of the rectangular trapezoidal faces in side of isosceles trapezoid two ends by its framework the opening inner edge of tabular pedestal joins with being  shape respectively, forms whole.

The utility model is that radiator shell is made an integral body together with the bottom of engine hood, last pressure floor, again bonnet fastening-clip is got on, seam crossing on horizontal and vertical both direction by in the past vertically change the angle that tilts into, like this owing to the applying of action of gravity engine hood and radiator shell is very tight, because the matrix of radiator shell extends to engine hood always, with the engine hood one integrated mass, both prevented the leakage in slit, reduced vibration again, such design cost is very low, and effect is very remarkable.

The utility model compared with prior art has simple and compact for structurely, and fabrication and installation are convenient, and cost is low, reduces characteristics such as noise effects is obvious.

Further specify the utility model below in conjunction with accompanying drawing.

Accompanying drawing is the utility model perspective view.

Among the figure: 1-radiator shell 2-pedestal.

As shown in drawings, be connected formation integral body with pedestal 2 below radiator shell 1 two ends.

Claims (1)

1. the all-in-one-piece pedestal of the bottom of an engine hood and radiator shell, the opening inner edge of tabular pedestal (2) joins with being  shape respectively at two ends down to it is characterized in that being the radiator shell (1) of the rectangular trapezoidal faces in side of isosceles trapezoid by framework, forms whole.
