Abstract

An oil dish of an automobile engine is made by pressing steel plates and comprises a bottom (1) and a side wall (2), a reinforcement groove (3) is arranged at the inner side face of the bottom (1), the edge of the side wall (2) forms a flanging (4), connection holes (5) are arranged on the flanging (4), the applied steel plate has a three-layer composite structure, wherein the outer two layers are thin steel plates, the interlayer is the vibration reduction and sound insulation layer thermally fixed with the outer two layers, the sound insulation is 0.045-0.055mm thick. After adopted the above proposal, the utility model strengthens the vibration reduction and sound insulation capacity of the whole oil dish. With the installation of the engine of this oil dish and other conditions unchanged, the noise emitted by the whole vehicle can be reduced by 2-3 db.

Description

The oil pan of motor car engine

Technical field

The utility model relates to engine fittings, relates in particular to the engine motor oil dish

Background technique

Oil pan is called oil sump again, is fixedly mounted on the lower end of cluster engine, belongs to the constituent element of engine lubrication system.When motor was not worked, all machine oil all left in the oil pan; During engine operation, part machine oil is stored in the oil pan, and remaining machine oil circulates between each parts of motor to play the effect of lubricated these parts.Oil pan plays an important role in the overall construction intensity of motor and transmission system, not only require its intensity, good rigidity, and stronger antivibration and noise resisting ability will be arranged, and therefore whole oil pan is except that having flange, and some grooves that also will distribute are to form stiffening rib.Existing motor car engine is weight reduction, oil pan adopts general steel sheet to be stamped to form usually, though satisfying requirement aspect rigidity and the intensity substantially, its soundproof effect is poor, a little less than the noise resisting ability, become the key factor that cluster engine and car load noise are big even exceed standard.

The model utility content

Problem to be solved in the utility model provides that a kind of antivibration ability is strong, and antinoise is effective, helps the oil pan of the motor car engine that cluster engine and car load noise reduce.

For solving the problems of the technologies described above, the oil pan of motor car engine of the present utility model, be stamped to form by steel plate, have bottom and gusset, the bottom inside face is distributed with the reinforcing groove, and the edge of gusset forms flange, be distributed with attachment hole on the flange, used steel plate is a three-layer composite structure, and wherein two outside layers is a sheet metal, and intermediate course is and two outside layers thermosetting vibration damping puigging together.

Because the used steel plate of oil pan punching press adopts the lamination layer structure of " sandwich " formula, thermosetting has the vibration damping puigging between the promptly two-layer outside general steel sheet, this vibration damping puigging uses viscoelasticity resin material or other similar material to make, make whole Clad Steel Plate have common individual layer armor plate strength height concurrently, plasticity reaches the good two-fold advantage of resin damping capacity well, the employed resin of vibration damping puigging has viscous-elastic behaviour preferably, can absorb mechanical vibration, make it to be converted into heat energy and discharge by outer layer plate, reduce vibration thereby reach, reduce anti noise.

The beneficial effects of the utility model are: strengthened whole oil pan antivibration and noise resisting ability, the motor of this oil pan has been installed, under the constant situation of other condition, its car load acceleration noise can descend 2～3 decibels.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the plan view of Fig. 1.

Fig. 3 is the A-A sectional view of Fig. 1.

Fig. 4 is the B-B sectional view (amplification) of Fig. 3.

Embodiment

As shown in Figures 1 to 4, oil pan through the motor car engine improved, be stamped to form by steel plate, have bottom 1 and gusset 2, bottom 1 inner side surface is distributed with reinforces groove 3, the edge of gusset 2 forms flange 4, be distributed with attachment hole 5 on the flange 4, used steel plate is a three-layer composite structure, wherein two

outside layers

6 and 7 is a sheet metal, and intermediate course 8 is and two

outside layers

6 and 7 thermosettings vibration damping puigging together that this vibration damping puigging adopts the viscoelasticity resin material to make, the below of flange 4 is welded with backing plate 9, to increase the join strength of itself and motor.Number in the figure 10 is a purge cock, and 11 is dividing plate.Middle resin sandwich has viscous-elastic behaviour preferably, can absorb mechanical vibration, make it to convert to heat energy, and distribute by two

outside layers

6 and 7, so the utility model reaches the good dual premium properties of resin damping capacity well with armor plate strength height, plasticity.

Thickness the best of intermediate course 8 is 0.045～0.055 millimeter, and big thick intensity and the plasticity that influences whole Clad Steel Plate has approached very much and then do not reached sufficient absorption vibration, reduced anti noise.

Claims

1, a kind of oil pan of motor car engine, be stamped to form by steel plate, have bottom (1) and gusset (2), bottom (1) inner side surface is distributed with reinforces groove (3), the edge of gusset (2) forms flange (4), is distributed with attachment hole (5) on the flange (4), and it is characterized in that: used steel plate is a three-layer composite structure, wherein two outside layers (6,7) is a sheet metal, and intermediate course (8) is and two outside layers (6,7) thermosetting vibration damping puigging together.

2, the oil pan of motor car engine according to claim 1 is characterized in that: the thickness of described intermediate course (8) is 0.045～0.055 millimeter.
