Abstract
The utility model discloses a two-layer crankcase oil tray for a diesel engine, which is characterized in that: a seal empty cavity is arranged between two layer steel plates and is provided with a radiation point which is a boss connected tightly with the two layer steel plates. The diameter of the boss is two to four mm; total area of the boss is 20 to 40 % of the surface area for the inner cavity of the crankcase oil tray; distance between the two layer steel plates is 2.5 to 5 mm. The utility model is used for holding oil for the bottom part of the diesel engine body. The utility model has the advantages of good rigidity, small vibration, ability of acoustic insulation, effectively lowering noise radiation for the diesel engine and lowering oil temperature due to even distributed radiation points with certain density between two layer steel plates, easy manufacturing and low cost.
Description
Technical field
The utility model relates to a kind of diesel engine oil pan, especially double-deck oil sump.
Background technique
Along with the speed up and the straight sprayization of diesel engine, its noise obviously raises.The oil sump that is contained in organism bottom is a large-area noise radiation part, it is carried out structural improvement can effectively reduce diesel engine noise.Diesel engine oil pan most of employing steel plate punching press at present or the individual layer oil sump that is welded into, the compound oil drain pan of filled high polymer material between the employing double-layer plate that also has.The individual layer oil sump, rigidity is poor, and easily vibration is big to extraradial noise; Though the compound oil drain pan can reduce noise, the manufacturing process complexity, cost is higher, and radiating effect is bad, causes machine oil obviously to heat up and loses efficacy.
The model utility content
The technical problems to be solved in the utility model is: a kind of double-deck diesel engine oil pan is provided, and it can reduce diesel engine work noise, can reduce the temperature of machine oil again, and low cost of manufacture.
The technical solution of the utility model is: the shape of double-deck diesel engine oil pan and diesel-engine body bottom space position adapt, between the double-layer plate of oil sump sealed cavity is arranged, be provided with the heat radiation point in the sealed cavity, this heat radiation point is the boss that closely links to each other with two-layered steel plates.
Further technological scheme is: described boss is the punching type circular protrusions part that is positioned on the inner layer steel plate and closely contacts with outer layer plate; The diameter d of described circular protrusions part is 2～4mm; The gross area of described circular protrusions part is 20～40% of an oil sump surface of internal cavity; The spacing b of double-layer plate is 2.5～5mm.
Adopt above technological scheme, the utility model is a double layer construction, airtight hollow out between the double-layer plate, and good rigidity is vibrated for a short time, and soundproof effect is good, can obviously reduce the noise radiation of diesel engine.The heat radiation point of certain density that distributes between double-layer plate guarantees the cooling of machine oil in the oil sump, avoids machine oil Yin Wendu too high and lost efficacy; The heat radiation point also plays the effect that strengthens the oil sump strength and stiffness.Can pass through the concrete parameter value that heat radiation point in the such scheme is determined in test according to diesel engine applying working condition and Environmental Conditions.Empirical tests, the utility model noise reduction spoke degree is that oil temperature remains on below 95 ℃ about 1.5dB (A).The utility model is welded after adopting the steel plate impact briquetting, and preparation process is simple, and cost is lower.
Description of drawings
Fig. 1 is automobile-used double-deck diesel engine oil pan structural representation;
Fig. 2 is the partial enlarged drawing of heat radiation point in A place among Fig. 1.
Embodiment
As figure, be welded into one after inner layer steel plate 1, outer layer plate 2 impact briquettings, closed cavity 3 is arranged between the two-layered steel plates.Heat radiation point 4 is the boss that are stamped to form on inner layer steel plate and closely contact with outer layer plate, and its diameter d is 3mm, and its gross area is about 30% of an oil sump surface of internal cavity.The spacing b of double-layer plate is 4mm.
Claims (5)
1, a kind of double-deck diesel engine oil pan, shape and diesel-engine body bottom space position adapt, and are double-layer steel plate structure, it is characterized in that sealed cavity is arranged between the double-layer plate, be provided with the heat radiation point in the sealed cavity, this heat radiation point is the boss that closely links to each other with two-layered steel plates.
2,, it is characterized in that described boss is the punching type circular protrusions part that is positioned on the inner layer steel plate and closely contacts with outer layer plate by the described double-deck diesel engine oil pan of claim 1.
