Description of drawings
Come the technical solution of the utility model is described in further detail below with reference to drawings and Examples, but should be known in these accompanying drawings only for task of explanation designs, therefore not as the restriction of the utility model scope.
Fig. 1 is an embodiment's of the utility model integrated engine oil pump sectional perspective structural representation.
Fig. 2 is Fig. 1 embodiment's worm's eye view.
Fig. 3 is Fig. 1 embodiment's plan view.
Embodiment
At first, need to prove, below will specify concrete structure, characteristics and the advantage etc. of integrated engine oil pump of the present utility model by way of example, however all descriptions only be used for describing, and it should be interpreted as the utility model is formed any restriction.In addition, in mentioned each embodiment of this paper, described or implicit any single technical characteristics, perhaps be shown or lie in any single technical characteristics in each accompanying drawing, still can between these technical characteristicss (or its equivalent), proceed combination in any or delete, thereby obtain of the present utility model more other embodiments that may directly not mention in this article.
Under request in person in conjunction with reference to figure 1-Fig. 3, show an embodiment's of this integrated engine oil pump essential structure by these accompanying drawings.As shown in the figure, in this embodiment, it mainly comprises housing, oil pump 1, single trunnion shaft 2, single trunnion shaft driving wheel 3, single trunnion shaft follower 4 and oil suction dish 5.Wherein, oil pump 1 is installed in enclosure interior, it links to each other with engine crankshaft by adopting the kinds of drive such as chain transmission or band transmission, and at the running shaft 6 of this oil pump 1 single trunnion shaft driving wheel 3 has been installed, has been rotatablely moved synchronously in order to when running shaft 6 is rotated, drive single trunnion shaft driving wheel 3.
