Abstract
The invention discloses a constant-temperature low-noise oil sump of an engine. The main body of the oil sump is designed as the double-layer sandwich structure. The internal layer is made from the common steel plate while the external layer is made from the composite damping steel plate. The bottom of the main body of the oil sump is provided with an inlet pipe of cooling liquid and an electromagnetic valve. The upper end of the main body of the oil sump is provided with an outlet of cooling liquid while the lower end thereof is provided with a temperature sensor. Transmission lines are connected between the temperature sensor and the electromagnetic valve which are connected with a controller. The bottom of the main body of the oil sump is provided with a lubricant discharging outlet. The external side of the main body of the oil sump is pasted with damping rubber. The oil sump is characterized in that: the shell of the oil sump is modeled by the stamping of double-layer vibration-decreasing steel plates; the temperature of the oil sump shell is maintained within a certain range by the circulation of the cooling liquid in the sandwich structure; the damping performance decline of the damping steel plates, caused by the temperature rise of the lubricant of the engine, is eliminated so as to possibly increase noises; therefore the noise-reducing design is considered for the oil sump structure so as to achieve the purposes of decreasing vibration and reducing noise of the oil sump.
Description
Technical field
The invention belongs to the Structure of Internal-Combustion Engine part, be specifically related to a kind of fuel tank drain pan with the effect of constant-temperature low-noise sound.
Background technique
The Engine Surface parts comprise cylinder cap, cylinder body-crankcase and several main case class part (cylinder head cover, gear chamber cover, oil sump) etc.Wherein the case class part of motor is the source that produces Surface Radiation Noise.As shown in Figure 1, account for 35% of total noise of centrifuge without the noise of Acoustic Optimization oil sump radiation when rotating speed is 3200r/min, if add cylinder head cover and gear chamber cover etc., the noise of these cap surface radiation will be above 1/2nd of total noise of centrifuge.In the motor thin-wall part, oil sump is the most typical structure, has maximum radiating surface, so the design of oil sump is all attached great importance to both at home and abroad.Thin walled structures in the motor is optimized design, and particularly being optimized design at oil sump is a key content that reduces the Radiated Noise of Engine Surfaces noise.
At present the main method that is optimized design at oil sump is to adopt the damping steel plate to make oil sump.But adopt damping steel plate to have two each and every one drawbacks: the one, the oil sump heat dispersion that damping steel plate is made is poor, causes the lubricating oil temperature height, influences the greasy property of motor moving element; The 2nd, the oil sump that damping steel plate is made damping capacity decline at high temperature causes noise reduction poor, even the situation that noise goes up not down occurs.For this reason, provide a kind of new structure oil sump of can vibration isolation, having the cutting oil effect simultaneously again to solve the noise problem of motor.
Summary of the invention
The purpose of this invention is to provide a kind of can cooled engine lubricant oil, and utilize suitable temperature to bring into play the oil sump of damping function simultaneously, to reach constant temperature noise reduction purpose.
Know-why of the present invention and scheme are as shown in Figure 2.Damping steel plate is to cause the rising of steel plate self temperature along with the rising of oil temperature as one of characteristic of engine sump tank, thereby causes vibration noise also can strengthen.The oil sump of the present invention's design is made of double-deck oil sump for this reason, be that the oil sump body design is a sandwich structure, in interlayer, circulate the heat of taking away lubricant oil by cooling liquid, it is constant in a certain scope to keep the oil sump temperature, and what the noise that the damping capacity decline that elimination causes damping steel plate because of engine lubricating oil heats up produces increased may.Consider the noise-reducing design of oil pan structure on this basis again, finally to reach damping steel plate oil sump vibration and noise reducing purpose.Cooling liquid feed liquor pipeline is provided with solenoid valve, be provided with the controller of temperature transducer and corresponding may command solenoid valve aperture in oil sump main body lower end, so by detecting the temperature of oil sump internal lubrication oil, regulate the flow of cooling liquid by solenoid valve, make its lubricating oil temperature stable within the limits prescribed.The double-deck damping plate enclosure of oil sump applies damping glue, can further increase noise reduction.

Fig. 2 is a structure principle chart of the present invention.
Embodiment
Below in conjunction with embodiment structural principle of the present invention is described further.Constant-temperature low-noise oil sump tank of engine has oil sump main body, solenoid valve, temperature transducer, controller and transmission cable etc.Oil sump main body 1 is designed to double-deck sandwich structure, and internal layer is a general steel plate, and skin is a composite damping steel plate, and cooling liquid circulates in interlayer, and the outside of oil sump main body 1 applies damping glue.The oil sump bottom part body is provided with cooling liquid liquid inlet pipe 2 and solenoid valve 3; Oil sump main body upper end is provided with cooling liquid liquid outlet 4; Oil sump main body lower end is provided with temperature transducer 5; Temperature transducer 5 and solenoid valve 3 are connected to transmission cable 6 link to each other with controller 7 (as Fig. 2).Cooling liquid comes from through fan-cooled engine cycles water, sends into oil sump main body interlayer by liquid inlet pipe 2 and solenoid valve 3, and cooling liquid absorbs the heat of lubricant oil in interlayer, and the cooling liquid that temperature raises enters engine cooling and circulating system, constitutes circulation.Lubricating oil temperature is by temperature transducer 5 tests in the oil sump, and feed back to controller 7 by transmission cable 6, after the oil temperature signal via controller is judged, output is carried out signal and is given solenoid valve 3, by the aperture size of temperature signal control electromagnetic valve, thereby lubricating oil temperature is in stable scope in the control oil sump.The oil sump bottom is provided with lubricant oil fuel outlet 8, and lubricant oil discharges by fuel outlet 8 in the oil sump.
Characteristics of the present invention are that the oil sump shell adopts double-deck sandwich, and wherein internal layer is general steel plate, and are outer for multiple Close the damping steel plate punch forming, so that the damping capacity of damping steel plate can be brought into play optimum efficiency under temperature constant state, thereby reach Purpose to noise reduction.
