Abstract

The utility model discloses an engine sump tank, comprising a tank body; sound insulation boards are respectively arranged on the two side surfaces of the inner cavity of the tank body, and the edges of the sound insulation boards are limited and closely attached to the side surface of the inner cavity of the tank body by a plurality of checking strips. The sound insulation boards respectively arranged on the two side surfaces of the inner cavity of the tank body can directly and effectively reduce the noise produced by engine radiation, and the construction to the existing sump tank is convenient and the manufacturing cost is low.

Description

A kind of engine sump tank

Technical field

The present invention relates to the technical field of engines of a kind of fuel oil, combustion gas, a kind of specifically engine sump tank.

Background technique

Along with the speed up of motor, its noise obviously raises now.The oil sump that is contained in organism bottom is a large-area noise radiation part, can effectively reduce engine noise to its structural improvement.Flat now mainly becomes double-deck improvement to the manufactured materials and the oil sump individual layer of oil sump, and its manufacture cost of this improvement all will improve greatly, also is difficult for the improvement of existing oil sump.

The patent No. is that the Chinese utility model patent of ZL03277850.3 discloses a kind of double-deck diesel engine oil pan, and sealed cavity is arranged between double-layer plate, is provided with the heat radiation point in the sealed cavity, and this heat radiation point is the boss that closely links to each other with two-layered steel plates.The boss diameter is 2～4mm, and the boss gross area is 20～40% of an oil sump surface of internal cavity, and the spacing of two-layered steel plates is 2.5～5mm.Its manufacture cost of the double-deck oil sump of this kind is apparently higher than the cost of individual layer oil sump, and flat effect and not obvious.

Summary of the invention

The utility model provides a kind of simple in structure, cheap for manufacturing cost and flat outstanding effect engine sump tank.

A kind of engine sump tank, comprise housing, housing inner chamber bi-side are respectively equipped with insulation board, the edge of insulation board is defined by several card articles and is close to housing inner chamber side, because the main area of housing concentrates on the inner chamber bi-side, the noise that engine body produces is radiated the external world in housing inner chamber bi-side, and noise is absorbed by large size and reduces noise behind the increase insulation board.

Described card article is fixedly connected on the side of housing inner chamber, and card article is connected with the side of housing inner chamber along its vertical part, and the gap is left in the side of another part and housing inner chamber, and this gap is inserted at the insulation board edge.The card article structure does not produce original oil sump and destroys and install simply, is connected firmly with insulation board.

Described insulation board is cut out two base angles trapezoidal, the convenient insertion in the card article.

Described insulation board is positioned housing inner chamber side by three card articles, and three card articles lay respectively at the both sides and the bottom of insulation board, and the position of insulation board is fixed, and can not be subjected to displacement under the normal conditions.

Described insulation board is made up of two blocks of alclad sheet therebetween one asbestos slates, the compactness of alclad sheet can intercept sound, the sound that sees through alclad sheet also will effectively be absorbed at the asbestos slate place, so can see through last one deck alclad sheet arrival outside sound will be a very little part, alleviate noise level greatly.

Described insulation board is a waveform, and soundproof effect is better like this.

The insulation board of the utility model engine sump tank inner chamber bi-side is provided with directly to effectively reduce and absorbs the noise that engine radiation comes out, and is convenient to existing oil sump transformation, low cost of manufacture.

Fig. 2 analyses and observe intention along the B-B line among Fig. 1;

Fig. 3 is an A position enlarged view among Fig. 1.

Embodiment

As shown in Figure 1, 2, 3, the utility model engine sump tank, comprise housing 1, housing 1 inner chamber bi-side are respectively equipped with insulation board 3, the edge of insulation board 3 is defined by several card articles 2 and is close to housing 1 inner chamber side, because housing 1 main area concentrates on the inner chamber bi-side, the noise that engine body produces is radiated the external world in housing 1 inner chamber bi-side, increases insulation board 3 back noises and is reduced noise by the large size absorption.

Card article 2 is fixedly connected on the side of housing 1 inner chamber, and card article 2 is connected with the side of housing 1 inner chamber along its vertical part, and the gap is left in the side of another part and housing 1 inner chamber, and this gap is inserted at insulation board 3 edges.Insulation board 3 is for cutting out the trapezoidal of two base angles, the convenient insertion in the card article.Insulation board 3 is positioned housing 1 inner chamber side by three card articles 2, and three card articles 2 lay respectively at the both sides and the bottom of insulation board 3, and the position of insulation board 3 is fixed, and can not be subjected to displacement under the normal conditions.Insulation board 3 also can be with being threaded, being welded to connect in the means of fixation of 1 liang of inner side surface of housing.Using card article to be connected and fixed insulation board 3 is the simple mode of a kind of most convenient comparatively speaking.

Insulation board 3 is made up of two alclad sheets, 4 therebetween, one asbestos slate 5, the compactness of alclad sheet 4 can intercept sound, the sound that sees through alclad sheet 4 also will effectively be absorbed at asbestos slate 5 places, so can see through last one deck alclad sheet 4 arrival outside sound will be a very little part, alleviate noise level greatly.Insulation board is a waveform, and sound wave extends along corrugated plate body and farthest lowered the noise volume.Certainly the composition of insulation board 3 also can be with the good material of some other sound-absorbing soundproof effect.
