Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality New protection domain is not restricted by specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " comprising " or its change It changes such as "comprising" or " including " etc. and will be understood to comprise stated element or component, and do not exclude other members Part or other components.
As shown in Figure 1 to Figure 2, according to specific embodiment of the present invention to achieve the above object, the utility model A kind of cylinder block low pressure oil recess structure is provided, is cast on the end face that cylinder block is combined with gear chamber, the end of cylinder block Face has high pressure sump 4, and high pressure sump 4 is communicated with the main oil gallery 1 of cylinder block.General engine mainly includes cylinder block, cylinder Lid and oil sump, cylinder block low pressure oil recess structure include left side low-pressure tank 3, right side low-pressure tank 2 and gear chamber cover board 5. Left side low-pressure tank 3 is arranged at the left side of high pressure sump 4;Right side low-pressure tank 2 is arranged at the right side of high pressure sump 4;Gear chamber Cover board 5 is between cylinder block and gear chamber;After so gear chamber cover board 5 is bonded with the end face of cylinder block, height can be both sealed Pressure oil groove 4 and left side low-pressure tank 3 and right side low-pressure tank 2, so as to form high-voltage oil cavity and left side low pressure oil pocket and Right side low pressure oil pocket, and wherein left side low pressure oil pocket and right side low pressure oil pocket are connected with oil sump.Lubricating oil is from cylinder block Main oil gallery 1 is arrived into high-voltage oil cavity, then is entered at the cylinder cap upper oil hole on high-voltage oil cavity top in the oil duct of cylinder cap for cylinder The cooling of cover and lubrication.
In some embodiments, left side low-pressure tank 3 includes oil return portion 31 on left side and is located at the upper of left side low-pressure tank 3 Portion;And oil return portion 32 is located at the lower part of left side low-pressure tank 3 under left side.And gear chamber cover board 5 include upper oil-recovery tank 51 and Lower oil-recovery tank 52, upper oil-recovery tank 51 are located at the top of gear chamber cover board 5 and cylinder block binding face, upper oil-recovery tank 51 and left side last time The position in oily portion 31 is corresponding.Lower oil-recovery tank 52 is located at the lower part of gear chamber cover board 5 and cylinder block binding face, lower oil-recovery tank 52 with The position in oil return portion 32 is corresponding under left side.Referring to Fig. 2, the lower part of 5 times oil-recovery tanks of gear chamber cover board 52 is not closing, this That is lower oil-recovery tank 52 is communicated with oil sump, so, can pass through from high-voltage oil cavity left upper portion oil spill Upper oil-recovery tank 51 smoothly enters left side low pressure oil pocket, can be suitable by lower oil-recovery tank 52 from high-voltage oil cavity left lower oil spill Profit enters left side low pressure oil pocket, and finally the lower part of oil-recovery tank 52 is returned to inside oil sump under process.
In some embodiments, right side low-pressure tank 2 is located at including oil return portion 21 under right side under right side low-pressure tank 2 Portion, and oil return portion 21 with oil sump is also what is communicated under right side, then oil spill can enter right side on the right side of from high-voltage oil cavity Low pressure oil pocket is then flow back into using oil return portion 21 under right side in oil sump.
Since the utility model arranges low pressure oil pocket at left and right sides of high-voltage oil cavity, when high-voltage oil cavity has oil from both sides It when leaking, will enter in the low pressure oil pocket of left and right, then along low pressure oil cavity wall under gravity toward low level stream It is dynamic, oil sump finally is back to from the oil-recovery tank on gear chamber cover board, so as to ensure that oil will not be leaked to engine surface.
In conclusion the cylinder block low pressure oil recess structure of the utility model is compared with prior art, due to high pressure sump and Low pressure oil pocket casts on body and forms, and substantially reduces and starts machining cost, and in low pressure oil pocket low level, arrangement Oil-recovery tank, oil sump can be smoothly back to by ensureing the oil of leakage, without being leaked to engine surface.
The description of the foregoing specific exemplary embodiment to the utility model is in order to illustrate and illustration purpose.These Description is not wishing to for the utility model to be defined to disclosed precise forms, and it will be apparent that according to the above instruction, can carry out Many change and variations.The purpose of selecting and describing the exemplary embodiment is that explain the certain principles of the utility model And its practical application, so that those skilled in the art can realize and utilize a variety of examples of the utility model Property embodiment and various chooses and changes.The scope of the utility model is intended to by claims and its waits similar shapes Formula is limited.
