Abstract
The utility model provides a cylinder block having an internally installed oil duct comprising an internally installed oil duct, a cylinder sleeve and a screwed hole used to connect the cylinder bolt; the cylinder block further includes a side oil duct connecting the main oil duct and the screwed hole. The beneficial effect of the utility model is that the integration of the side oil duct into the cylinder block simplifies the placement of components located on the outer part of the cylinder block, and further more, eliminates the introduction of an externally installed oil pipe between the main oil duct and the cylinder cover. Finally, the cylinder block has a more compact structure.
Description
[technical field]
The utility model relates to cylinder oil duct placement technique field, particularly a kind of cylinder block with built-in oil duct.
[background technique]
The lubrication system function is exactly the friction surface that the clean oil delivery continuously enough quantity when engine operation, that temperature is suitable arrives whole driving components, and between rubbing surface, form oil film, realize liquid friction, thereby reduce surface friction drag, reduce power loss, alleviate component wear, to reach the purpose that improves engine operation reliability and durability.The moving element of existing its cylinder block of petrol engine and cylinder head all needs the lubricated of lubricant oil, particularly the needed lubricant oil of engine cylinder cover also need be by external line transportation independently, and such structure does not cause structure compact and be unfavorable for the layout of motor complete machine.
[model utility content]
In order to solve existing technical problem, the utility model provides a kind of cylinder block with built-in oil duct, and it is by the built-in bypass oil duct of cylinder block, under the prerequisite that does not increase external oil pipe, realize the lubricated of cylinder cap, make the motor complete machine structure simplify, arrange compacter.
The utility model solves existing technical problem, and a kind of cylinder block with built-in oil duct is provided, the tapped hole that the main oil gallery of establishing in it comprises, cylinder sleeve and being used for links to each other with cylinder bolt; This cylinder block also comprises the bypass oil duct, and described bypass oil duct is communicated with described main oil gallery and described tapped hole.
The utility model further improves:
Described bypass oil duct comprises the first bypass oil duct and the second bypass oil duct.
Described cylinder sleeve is at least two, the described first bypass oil duct that communicates with described main oil gallery in the connection part setting of two adjacent described cylinder sleeves.
The described second bypass oil duct is communicated with described first bypass oil duct and described tapped hole.
Compared to prior art, the beneficial effects of the utility model are:
1) because the bypass oil duct is integrated in the cylinder block, simplified the layout of cylinder block peripheral element;
2) save external oil duct pipe between main oil gallery and the cylinder cap;
3) cylinder structure is compacter.
[description of drawings]
Fig. 1 is the outside schematic representation that the engine cylinder-body that the utility model proposes is connected with cylinder cap;
Fig. 2 is the A-A schematic cross-section of Fig. 1;
Fig. 3 is the enlarged diagram in B zone among Fig. 2;
Fig. 4 is the C-C schematic cross-section of Fig. 2.
[embodiment]
Below in conjunction with description of drawings and embodiment the utility model is further specified.
As shown in Figures 1 to 4, the tapped hole 3 that a kind of cylinder block 100 with built-in oil duct, the main oil gallery of establishing in it comprises 1, cylinder sleeve 2 and being used for link to each other with cylinder bolt 21; This cylinder block 100 also comprises bypass oil duct (the bypass oil duct comprises the first bypass oil duct 41 and the second bypass oil duct 42), and described bypass oil duct is communicated with described main oil gallery 1 and described tapped hole 3.
Cylinder cap 200 is fixed on the cylinder block 100 through cylinder bolt 21, and cylinder bolt 21 is threaded togather with tapped hole 3, and between the two matching gap is arranged.Streams have lubricant oil in the main oil gallery 1 in the cylinder block 100, and this lubricant oil enters in the tapped hole 3 via the bypass oil duct, rise to the cylinder cap position along the matching gap of tapped hole 3 and cylinder bolt 21, thereby have realized the lubricated of cylinder cap.
Described bypass oil duct comprises the first bypass oil duct 41 and the second bypass oil duct 42, is limited to the manufacturing process in hole, and the bypass oil duct that connects main oil gallery 1 and tapped hole 3 is designed to the orthogonal first bypass oil duct 41 and the second bypass oil duct 42.Particularly, described cylinder sleeve 2 is at least two, and at the described first bypass oil duct 41 that the connection part setting of two adjacent described cylinder sleeves 2 communicates with described main oil gallery 1, connection part is the transition region between the cylinder sleeve.The described second bypass oil duct 42 is communicated with described first bypass oil duct 41 and described tapped hole 3.
The utility model has been simplified the layout of cylinder block peripheral element because the bypass oil duct is integrated in the cylinder block; Secondly, save the external oil duct pipe between main oil gallery and the cylinder cap; At last, cylinder structure is compacter.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
