Description
Technical field
The present invention relates to a kind of engine components, specifically, relate in particular to the motorcycle crankcase cover structure on the motor.
Background technique
At present, traditional crankcase cover is the monolithic construction of the uncovered back-end closure of front end, and clutch operating device and push rod are installed in the closed end of crankcase cover, and both interconnect, the action of clutch operating device passes to clutch by push rod like this, so that solenoidoperated cluthes separate or engage.There is serious use defective in above structure: when needs repair or replace engine clutch, whole engine crankshaft case lid all must be disassembled, not only complex operation, waste time and energy, and frequent easy disassembling destroys the sealing of crankcase and the dynamic balancing of bent axle, whenever tear open on the one hand once and just must change the crankcase cover sealing gasket, cost is high; On the other hand, can make the stationarity of crankshaft operation descend the vibration that has strengthened engine operation.
In traditional crankcase structure, spin-on oil filter is installed on the bent axle, and with the bent axle high speed rotating, the centrifugal force that produces by rotation removes the impurity in the machine oil.Because spin-on oil filter is positioned at crankcase, when needing to be serviced or change, must dismantle crankcase cover and bent axle, not only operating difficulties, efficient are lower, and frequent easy disassembling destroys the sealing of crankcase and the dynamic balancing of bent axle, the stationarity of crankshaft operation is descended, and working life of bent axle has been shortened in the vibration that had both strengthened engine operation again.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of motorcycle crankcase cover structure, with convenient clutch and oil filter is safeguarded or is changed.
Technological scheme of the present invention is as follows: a kind of motorcycle crankcase cover structure, comprise crankcase cover, clutch separation lid, filter core and the cover of oil filter of being with inner chamber, wherein the front end of crankcase cover is uncovered, rear end at crankcase cover offers window, this window is by the sealing of clutch separation lid, cover in clutch separation and to be disposed radially the operating handle hole, the upper end in described operating handle hole connects to the end face of clutch separation lid, the lower end in operating handle hole extends to the middle part of clutch separation lid, and communicates with the inner chamber of crankcase cover by push-rod hole; Starting shaft first via hole and containing groove are set on the next door of described crankcase cover window, wherein starting shaft first via hole communicates with starting shaft second via hole butt joint that clutch separation covers, the cell wall of described containing groove is offered oil inlet hole and oil outlet respectively, and oil outlet connects the front-end face to crankcase cover; In described containing groove, filter core is installed, and the notch of containing groove is sealed by cover of oil filter, and cover of oil filter is provided with oil duct, and the import of this oil duct communicates with the inner chamber of crankcase cover by oil inlet hole, the outlet of oil duct is positioned at the bottom surface of cover of oil filter, and communicates with the inside of filter core.
The present invention is on the basis of conventional construction, window is offered in rear end at crankcase cover, and be equipped with a clutch separation lid that adapts with this window shape size, the clutch separation lid is fixed on the crankcase cover, on the one hand window is sealed, can install for clutch operating device and push rod on the other hand, be specially: clutch operating device is located in the operating handle hole that clutch separation covers, clutch push rod is located in the push-rod hole that clutch separation covers, and clutch push rod is connected with clutch operating device, the action of clutch operating device can pass to clutch in the crankcase by clutch push rod like this, makes clutch or separation.When needs to the clutch place under repair, when changing, can be under the prerequisite of not removing crankcase cover, directly the clutch separation lid is pulled down from crankcase cover, window from crankcase cover takes out clutch in crankcase, not only simple to operate, workload is little, efficient is higher, and can not destroy the sealing of crankcase and the dynamic balancing of bent axle.
