To achieve these goals, the utility model adopts following technological scheme: the large oil sump motor of a kind of motor tricycle, containing crankcase, crankcase madial wall arranges lubricating oil return mouth near cylinder body side, crankcase bottom arranges lubricating pump filler opening near cylinder body place, be positioned at and below described lubricating oil return mouth, casing is set strengthens horizontal bar in crankcase, horizontal bar strengthened by casing is upper space and lower space by crankcase interior separation, and casing is strengthened horizontal bar and deviated from described lubricating oil return mouth side and arranged hydraulic fluid port.
Preferably: above-mentioned casing strengthen horizontal bar by near lubricating oil return mouth side, horizontally disposed first strengthen horizontal bar with deviate from lubricating oil return mouth side, downward-sloping second strengthen horizontal bar and form.
Preferably: above-mentioned crankcase bottom, and cross between hydraulic fluid port and described lubricating pump filler opening described, oil baffle is set.
Preferably: above-mentioned crankcase bottom and described lubricating pump filler opening are oppositely arranged oil screen assembly department, oil screen assembly department installs oil screen, and the distance of lubricating pump filler opening and described oil screen is 0.1 ~ 1.1cm.
Preferably: the axis of above-mentioned lubricating pump filler opening rolls oblique 4.5 ~ 5.5 degree relative to vertical line toward lubricating oil return mouth.
Preferably: the axis of above-mentioned lubricating pump filler opening rolls oblique 5 degree relative to vertical line toward lubricating oil return mouth.
Compared with prior art, the utility model has following beneficial effect:
(1) increase casing and strengthen horizontal bar, make casing top and lower box (oil sump) there is certain isolation, increase oil baffle simultaneously.In engine operation process, machine oil back-flow velocity slows down, and effectively takes away cylinder body and cylinder head heat, improves overall performance; Machine oil back-flow velocity slows down, and can not take away the impurity of bottom half deposition, reduce the wearing and tearing to engine component, improves engine reliability.
(2) filler opening of oil pump is reduced.Optimize casing lubricating pump filler opening, after pasta tilts, pumping ability can not decline, and improves complete machine cooling effect, promotes engine reliability further.

Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 1 to Fig. 5, the large oil sump motor of a kind of motor tricycle, there is crankcase 9, crankcase 9 is by a left side, right crankcase 2, 1 composition, crankcase madial wall arranges lubricating oil return mouth 3 near cylinder body side, in embodiment, lubricating oil return mouth 3 is arranged on left crankcase, bottom crankcase 9, lubricating pump filler opening is set near cylinder body 8 place, in embodiment, lubricating pump filler opening 6 is arranged on bottom right crankcase 1 near cylinder body 8 side, be positioned at and below lubricating oil return mouth 3, casing is set strengthens horizontal bar 4 in crankcase 9, horizontal bar 4 strengthened by casing is upper space and lower space by crankcase 9 interior separation, and casing is strengthened horizontal bar 4 and is deviated from lubricating oil return mouth 3 side and arranged hydraulic fluid port, the lubricant oil flowing into casing reinforcement horizontal bar flows into crankcase bottom from here.In embodiment, casing strengthen horizontal bar by near lubricating oil return mouth side, horizontally disposed first strengthen horizontal bar with deviate from lubricating oil return mouth side, downward-sloping second strengthen horizontal bar and form.Through above-mentioned improvement, in engine operation process, machine oil back-flow velocity slows down, and effectively takes away cylinder body and cylinder head heat, improves overall performance.
Crankcase bottom, and crossing between hydraulic fluid port and described lubricating pump filler opening, oil baffle 5 is set.Machine oil back-flow velocity slows down, and can not take away the impurity of bottom half deposition, reduce the wearing and tearing to engine component, improves engine reliability.
Crankcase bottom and described lubricating pump filler opening are oppositely arranged oil screen assembly department 6a, and oil screen assembly department 6a installs oil screen, and lubricating pump filler opening 6 is 0.1 ~ 1.1cm with the distance of oil screen.
The axis of lubricating pump filler opening 6 rolls oblique 4.5 ~ 5.5 degree relative to vertical line toward lubricating oil return mouth 3, and preferably, tilting value is 5 degree.
The defect that the application exists for prior art, change engine case body structure, under ensureing demoulding prerequisite, increases casing and strengthens horizontal bar, make casing top and lower box (oil sump) there is certain isolation.Machine oil back-flow velocity is slow, solves the problems such as heat load is high.Bottom oil sump, increase oil baffle plate, again reduce machine oil back-flow velocity, impel the impurity rapid precipitation in machine oil, avoid impurity again to enter the inner wearing and tearing causing component of complete machine.Reduce the filler opening of oil pump, reduce about 40mm on the original basis, on former motor basis, many 5 degree tilt, and pumping ability is still normal, promotes the reliability of motor.
When in engine operation process, cool the machine oil after cylinder head 7 and cylinder body 8 and flow to casing reinforcement horizontal bar 4 by the lubricating oil return mouth 3 on left crankcase, at this moment engine oil flow speed is slowed down rapidly, and the radiating fin that the heat in machine oil is passed on crankcase 9 is entered air.Oil baffle 5 slows down machine oil flow velocity again, impels the Impurity deposition in machine oil.And then cooled by the 6 pairs of cylinder heads 7 of the lubricating pump filler opening on right crankcase and cylinder body 8.Facts have proved that the program can solve the various problems without oil sump motor effectively.
The foregoing is only preferred implementation of the present utility model, protection domain of the present utility model is not limited in above-mentioned mode of execution, and every technological scheme belonging to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, the some improvement carried out under the prerequisite not departing from principle of the present utility model, these improvement also should be considered as protection domain of the present utility model.
