Abstract
The invention provides an oil bottom case structure with an enhanced oil return function. The oil bottom case structure comprises an oil bottom case body, wherein an oil collecting pool is arranged at each of the front and back ends of the oil bottom case body, a bottom plate of the oil bottom case body arranged between the two oil collecting pools is of an inclined structure with the higher middle and the lower two ends, and the two oil collecting pools are not symmetrical along the transverse center line of the oil bottom case body, and are respectively positioned at the two sides of the center line. The oil bottom case structure has the advantages and positive effects that the positions and the number of the oil collecting pools are regulated, in addition, the inclined structure of the oil bottom case (or a lower crank case) is added, the backflow gathering capability of engine oil can be obviously improved, meanwhile, the continuous oil return when the engine generates front back left and right inclination can be ensured, the oil collecting pools are respectively arranged in the center symmetry positions of the two sides of the front end and the back end of the oil bottom case, in addition, the inclined structure with the higher middle and the lower two ends is designed at the inner side of the bottom plane of the oil bottom case, and when the engine inclines in the front back left and right direction, the backflow gathering effect of the engine oil is not influenced.
Description
Technical field
The invention belongs to diesel engine oil pan technical field of structures, especially relate to a kind of oil pan structure strengthening oil return function.
Background technique
In prior art, the oil sump (or lower crankcase) of high-power diesel engine, usually there is the function collecting machine oil, its structural design is the stamping part of a thin-shell construction or the foundry goods of thin aluminium case structure, the machine oil flowing through each lubricating structure collects in oil sump (or lower crankcase) because of Action of Gravity Field, through return line and oil pump, reenter lubrication system.The diesel engine oil pan (or lower crankcase) of part model, is also designed with oil sump, is generally positioned at the middle bottom of casing, is furnished with fuel outlet valve and return line in it, and collecting of machine oil is strengthened to some extent with reflux capability.
But, said structure design, when there is the inclination of wide-angle all around in motor in vehicle travel process, machine oil cannot normal reflow in oil sump, the normal work of oil pump and the lubricating efficiency of lubrication system can be affected.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of oil pan structure strengthening oil return function.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
Strengthen an oil pan structure for oil return function, comprise oil sump body, the rear and front end of described oil sump body is respectively provided with an oil sump, and the base plate of the oil sump body between described two oil sumps is the low leaning structures in middle high two ends.
Further, the cross central line of described two oil sumps not along oil sump body is symmetrical, lays respectively at the both sides of center line.
The advantage that the present invention has and good effect are:
The position of oil sump and quantity are adjusted, and add the leaning structure of oil sump (or lower crankcase) base plate, such structural design, what both can significantly improve machine oil collects reflux capability, can guarantee the uninterrupted oil return when motor appearance is tilted all around simultaneously;
Oil sump is arranged in the centrosymmetric position, both sides, front end and back end of oil sump, and devises leaning structure high in the middle and low on both ends inside the bottom plane of oil sump, when motor all around tilts, what do not affect machine oil collects backflow;
Motor, when normal horizontal position works, because of the leaning structure inside base plate, also accelerates the speed that machine oil is back to oil sump, effectively improves oil sump oil-collecting and oil return ability.
Accompanying drawing explanation
Fig. 1 is plan view of the present invention;
Fig. 2 is longitudinal section of the present invention.
In figure:
1-oil sump body, 2-oil sump, 3-base plate.
Embodiment
It should be noted that, when not conflicting, the embodiment in the present invention and the feature in embodiment can combine mutually.
Below in conjunction with accompanying drawing, specific embodiments of the invention are elaborated.
A kind of oil pan structure strengthening oil return function, as shown in Figure 1, 2, comprise oil sump body 1, the rear and front end of described oil sump body 1 is respectively provided with an oil sump 2, and the base plate 3 of the oil sump body 1 between described two oil sumps 2 is the low leaning structures in middle high two ends; When tilting forward and back appears in motor, collect machine oil by former and later two oil sumps 2 respectively; The inclined design high in the middle and low on both ends of described base plate 3 is conducive to machine oil quick backflow in the oil sump 2 at two ends.
The cross central line of described two oil sumps 2 not along oil sump body 1 is symmetrical, and lay respectively at the both sides of center line, when tilting appears in motor, the design of disalignment makes different oil sumps 2 play a role.
Motor, when normal horizontal position works, because of the leaning structure inside base plate 3, also accelerates the speed that machine oil is back to oil sump 2, effectively improves oil sump 2 oil-collecting and oil return ability.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
Claims (2)
1. strengthen the oil pan structure of oil return function for one kind, comprise oil sump body (1), it is characterized in that: the rear and front end of described oil sump body (1) is respectively provided with an oil sump (2), the base plate (3) of the oil sump body (1) between described two oil sumps (2) is the low leaning structure in middle high two ends.
2. the oil pan structure of strengthening oil return function according to claim 1, is characterized in that: the cross central line of described two oil sumps (2) not along oil sump body (1) is symmetrical, lays respectively at the both sides of center line.
