Description
Technical field
The present invention relates to the lubricating structure of motorcycle engine, particularly a kind of full-filtration type external filter element oil path of motorcycle engine.
Background technique
Need the machine oil filtrating equipment on the oil circulation oil circuit of motor, be transported to the part place that each need lubricate again after circuit machine oil is filtered, improve the mechanical motion performance, guarantee the motor proper functioning.Tradition tappet rod type Engine Series machine oil filters and has passed through the twice filter screen, and first road is for being located at strainer in the oil pan, and second road is the secondary filter of being located on the crankcase.The secondary filter of present tappet rod type Engine Series is arranged on the bent axle, mould assembling face at right crankcase cover is provided with an oil groove, being provided with a hole in this oil groove communicates with secondary filter, another oil groove that is provided with on the mould assembling face of oil groove and right crankcase is corresponding, form oil duct after the mould assembling, right crankcase is provided with oil duct access to engine cylinder head.During engine operation, machine oil in the oil pan is sent into the oil groove of the mould assembling face of right crankcase by oil pump after coarse filtration, after machine oil enters oil groove, enter right crankcase cover by oil groove again, wherein a part enters secondary filter and filters, directly carry after the filtration to bent axle, and some machine oil does not enter secondary filter just directly from the oil groove downstream transport, this just causes the machine oil of lubricating detail all not obtain smart for the second time filter, reduced the cleanliness of lubricant oil widely, when motor is installed in usually on the comparatively abominable motor tricycle of applying working condition, this lubricating requirement that just can not satisfy use motor under bad working environments fully through the lubricating oil of the smart filter of secondary, cause the performance of the motor of motor tricycle to reduce, shorten working life.
Summary of the invention
The objective of the invention is deficiency, a kind of full-filtration type external filter element oil path of motorcycle engine is provided at the prior art existence.It can make the machine oil that enters lubricating oil path all through after the smart once more filter of secondary filter, just is delivered to the downstream part of motor is lubricated, and improves the cleanliness of lubricating oil, guarantees the proper functioning of motor and the working life of prolongation motor.
The object of the present invention is achieved like this: right crankcase covers and is provided with the chamber that machine oil filter core is installed, and the oil inlet hole that is communicated with oil pump, the mould assembling face of right crankcase cover is provided with the oil groove as oil duct, two oil grooves are set respectively on the mould assembling face of described right crankcase cover, the entity part of partition two oil grooves between two oil grooves flushes with mould assembling face, two oil grooves are communicated with by the oil duct of being located in the right crankcase cover entity respectively with the chamber that machine oil filter core is installed, in two oil grooves, first oil groove is located at the upstream of machine oil filter core, the oil inlet hole that is communicated with oil pump is arranged in first oil groove, second oil groove is located at the downstream of machine oil filter core, and described two oil grooves are located at the position near the chamber that machine oil filter core is installed respectively.
The chamber of described installation machine oil filter core is provided with entering the hole and portalling of machine oil, enters the hole and communicates with first oil groove, and portalling communicates with second oil groove and crankshaft installed counterbore.
Described portalling is provided with internal thread, and machine oil filter core is connected in the chamber of the installation machine oil filter core that right crankcase covers with the screw-thread fit of portalling.
Described two oil grooves and install oil duct between the chamber of machine oil filter core be located at respectively with the integrated convex tendon of right crankcase cover in.
Owing to adopt technique scheme, two oil grooves are set on the mould assembling face of right crankcase cover, two oil grooves are communicated with by the oil duct of being located in the right crankcase cover entity respectively with the chamber that machine oil filter core is installed, first oil groove is located at the upstream of machine oil filter core, second oil groove is located at the downstream of machine oil filter core, make thus through the machine oil of coarse filtration all once more through just entering the lubricating oil path in downstream after the smart filter, the part of motor is lubricated, improve the cleanliness of circulation machine oil.The entity part of partition two oil grooves between described two oil grooves flushes with mould assembling face, can guarantee to form sealing after the mould assembling, prevents that the machine oil of first oil groove from directly scurrying in second oil groove, influences the cleaning of lubricating oil.
The chamber of described installation machine oil filter core is provided with entering the hole and portalling of machine oil, entering the hole communicates with first oil groove, portal and communicate with second oil groove and crankshaft installed counterbore, the machine oil that the upstream is carried enters the machine oil filter core filtration from advancing after the hole enters the chamber that machine oil filter core is installed again, machine oil after the filtration is transported to lubricated bent axle the bent axle counterbore in downstream from machine oil filter core through portalling, be transported to simultaneously in second oil groove, the oil duct on the right crankcase after the corresponding mould assembling with right crankcase cover is transported to the lubricated distribution device of cylinder head then.Described portalling is provided with internal thread, and machine oil filter core is connected in the chamber of the installation machine oil filter core that right crankcase covers with the screw-thread fit of portalling.Making portals can send machine oil, can be used for installing and fixing of machine oil filter core again, has simplified the structure of right crankcase cover.
The present invention is further illustrated below in conjunction with drawings and Examples.
Description of drawings
