Abstract
The invention provides an oil pan for motors, which comprises a large end face of the oil pan, an internal cavity of the oil pan, a back end face and a bottom of the oil pan, and is characterized in that the internal cavity of the oil pan is provided with internal cavity reinforcement that can reinforce and reduce noises; the bottom of the oil pan is provided with bottom reinforcement; the back end face of the oil pan is provided with back end reinforcement; the back end face of the oil pan is designed into a semi-circle shape, which is similar to the end face shape of the gear-box, and two bolt holes that connect the oil pan and the gear-box are added on the back end face of the oil pan, so the oil pan can be connected with the gear-box directly. The oil pan is set higher than the high-pressure oil channel to favor the arrangement of the whole machine. As the twisted reinforcement that can reinforce and reduce noises are arranged in the internal cavity and the bottom of the oil pan, the noise of oil pan is reduced. As two bolt holes that connect the oil pan and the gear-box are added on the back end face of the oil pan, the oil pan can be connected with the gear-box directly, thereby reducing the guard plates for the motor and the gear-box, reducing the procedure for assembly and reducing the cost. As the high-pressure oil channel is arranged in the internal cavity of the oil pan, the oil channel can convey the high-pressure oil from the oil pump to the motor frame, which is favorable to the arrangement of the whole machine.
Description
Technical field
The present invention relates to a kind of engine components, more specifically to a kind of structural design of automobile engine oil pan.
Background technique
Engine sump tank is a shaping steel food tray, and protection motor bottom also is the oil depot of motor simultaneously.In the past, oil sump mainly divided two kinds:
First kind is the punching oil drain pan, adopts sheet metal that oil sump is gone out.This oil pan structure is simple, and easy deformation in the vehicle driving process causes the poorly sealed generation oil impregnate of oil sump and cylinder body.The punching oil drain pan belongs to sheet member simultaneously, and under the high frequency vibration, noise is very big, and machine oil is vaporization easily also.When motor and gearbox assembling, need increase the assembling backplate.
Second kind for adopting the oil sump of aluminum-magnesium alloy material casting, this oil sump has only the bottom to arrange the processing muscle, reduce a little less than the noise ability, inner chamber does not have the oil duct layout simultaneously, therefore on engine cylinder-body, need to arrange two oil ducts, increased the difficulty of cylinder casting and processing, needed perhaps to arrange that independent pipeline is transported to cylinder body with the oil of oil pump outlet.Simultaneously, be unfavorable for the layout of complete machine, also cause machine oil gasification and loss easily.
Summary of the invention
The technical problem to be solved in the present invention is, in order to remedy the deficiency of available engine oil sump, and a kind of high strength is provided, highly reduces noise, is beneficial to the layout of complete machine, engine sump tank rational in infrastructure.
The present invention solves the problems of the technologies described above to adopt following technological scheme:
A kind of engine sump tank comprises oil sump large end face, oil sump inner chamber, ear end face and oil sump bottom, it is characterized in that: the inner chamber muscle that reinforcement, reduction noise are set at the oil sump inner chamber.
For make reinforcement, to reduce noise better, in the oil sump bottom bottom muscle is set.
For further strengthening, reducing noise, the rear end gluten is set at the oil sump ear end face.The oil sump ear end face is designed to semicircle, close with the shape of transmission housing end face, and on the oil sump ear end face, increase by two bolts hole that connect oil sump and gearbox, oil sump directly can be connected with transmission housing.
For the benefit of the layout of complete machine is provided with the oil sump high-pressure oil duct at oil sump.
Good effect of the present invention is, oil sump is the oil sump of casting, and the oil sump large end face is the plane, directly seals with liquid sealant.This mode seals simply, is not easy to produce engine oil leakage.In the process of motor operation, oil sump be engine noise main source it.Oil sump inside is a cavity volume, is the place that produces the noise maximum, arranges the muscle of tendency meander-shaped in the oil sump inner chamber, can form the radiation row, and sound wave can weaken gradually, can reduce the oil sump noise.Arrange staggered anyhow muscle in the bottom of oil sump simultaneously, with the comfort level that improves car load direct influence is arranged all to improving the motor operation conditions to a great extent.The oil sump ear end face is designed to semicircle, close with the shape of transmission housing end face, and on the oil sump ear end face, increase by two bolts hole that connect oil sump and gearbox, oil sump directly can be connected with transmission housing, reduce the backplate of motor and gearbox, reduce the operation of assembling, reduce cost.The quality of arranging the muscle minimizing oil sump of some on the oil sump ear end face reduces oil sump and the bigger noise of clutch junction plane place generation simultaneously.In the oil sump inner chamber, arrange high-pressure oil duct.This oil duct can make the high pressure oil that pumps from oil pump be transported to engine frame, and does not need other to add metal tubes, has reduced the vaporization of machine oil, and oil consumption is reduced.Need on engine cylinder-body, not increase the oil duct that the oil that oil pump is pumped is transported to cylinder body yet, and make the difficulty increase of arranging two oil ducts on the cylinder body and making cylinder casting and processing, improve the cost of motor.
Further specify the present invention below in conjunction with embodiment and accompanying drawing.
Description of drawings
Fig. 1 is existing punching press type oil pan structure schematic representation.
Fig. 2 is the oil pan structure schematic representation of existing employing aluminum-magnesium alloy casting.

Fig. 4 is the constructing stereo figure of oil sump of the present invention.Oil sump external structure is shown.
Among the figure: 1, large end face, 2, inner chamber, 3, the inner chamber muscle, 4, the bottom muscle, 5, ear end face, 6, the rear end gluten, 7, bolt hole, 8, high-pressure oil duct 9, oil pump oil outlet 10, framework filler opening 11, tapered plug.
Embodiment
Fig. 1 is existing punching press type oil pan structure schematic representation, and Fig. 2 is the oil pan structure schematic representation of existing employing aluminum-magnesium alloy casting.Oil sump among Fig. 1 is for directly to come out with the sheet metal punching press.From the diagram can find out that this kind is simple in structure, without any oil duct and stiffening rib.Easy deformation in the vehicle driving process and make the poorly sealed oil impregnate that occurs between cylinder body and the oil sump.This oil sump belongs to sheet member simultaneously, in vibration processes, produces very big noise.Oil sump among Fig. 2 is directly cast for adopting aluminum alloy or magnesium alloy.The oil sump inner chamber does not have muscle and oil duct, and is poor to the oil sump noise reduction effect.The oil sump ear end face is simple in structure, does not arrange the bolt hole that muscle and assembling gearbox are used.
