Abstract
The invention provides an engine lubrication oil way structure. A sealing tendon is arranged between a power cavity and a transmission cavity of a left case and a right case, the sealing tendon is used as an oil separation belt to completely separate the power cavity and the transmission cavity of the engine after the pick-up fitting of the case closing surfaces of the left case and the right case, the left case and the right case respectively form a power cavity lubrication oil way and a transmission cavity lubrication oil way which are mutually independent, the power cavity lubrication oil way is communicated with an oil sump at the bottom of the power cavity, and the transmission cavity lubrication oil way is communicated with an oil sump at the bottom of the transmission cavity. On the basis of not changing the contour of the engine and the position of the suspension interface, the engine double-lubrication oil way structure realizes the separation of thermal engine lubrication oil and cold engine lubrication oil, is beneficial to the improvement on engine performance and prolonging of the service life of the engine.
Description
Technical field
The present invention relates to motor, especially the lubricant oil road structure of motor.
Background technique
The power cavity (hot machine part) of existing tappet rod type motorcycle four-stroke engine lumps together with the lubrication system of drive cavity (cold machine is the gearbox drive part), uses with a kind of lubricant oil.Structurally show as: power cavity communicates with drive cavity, lowest part forms shared lubricating oil bath in the chamber, whole motor adopts a cover lubrication system, such lubricant oil road structure is concerning the use of common two-wheeled motor vehicle under conventional environment, be enough to satisfy usage requirement, but concerning the comparatively abominable motor tricycle of applying working condition, its lubricant oil can not satisfy the lubricated normally and cooling needs of motor, if the temperature drift of drive cavity, too high and the phenomenon of emulsification of lubricant oil Yin Wendu appears easily, and, because drive cavity can produce impurity in operation process, these impurity enter power cavity with lubricant oil, make the lubricant oil of power cavity become unclean, increase bent axle by the probability of locking, influenced the reliability and the working life of motor.
Summary of the invention
The purpose of this invention is to provide a kind of engine double-lubrication oil way structure, this lubricant oil road structure separates operation alone with the power cavity and the lubrication system of drive cavity, helps to improve engine performance, improves the working life of motor.
For solving the problems of the technologies described above, engine double-lubrication oil way structure provided by the invention, be between the power cavity of left and right sides casing and drive cavity, to be provided with sealed muscle, left and right sides casing mould assembling in the face of the tipping join after, sealed muscle is separated the power cavity and the drive cavity of motor fully as the oil removal band, on the casing of the left and right sides, be formed with separate power cavity lubricating oil path and drive cavity lubricating oil path, the power cavity lubricating oil path is communicated with the oil sump of power cavity bottom, and the drive cavity lubricating oil path is communicated with the oil sump of drive cavity bottom.
The present invention has realized the separation of engine thermal machine and cold machine lubricant oil, and the drive part lubricating oil temperature is reduced, thereby minimizing even elimination are because the phenomenon of the too high emulsification of lubricant that causes of temperature; Because lubricating oil separation makes the also corresponding minimizing of lubricant oil that needs by the cooling system cooling, make the lubricating oil temperature of hot machine part also obtain reduction, thereby improve engine performance and life-span; After the lubricating oil separation, the impurity that drive part produces in operation process can not gone to hot machine and partly go, thereby the lubricant oil of hot machine part is more cleaned, significantly reduced the probability of faults such as bent axle locking, satisfied particularly tricycle user's demand of certain customers.
Further, two oil pumps are installed on right case, two coaxial assemblings of oil pump and by crank-driven, being communicated with the power cavity lubricating oil path of one of them oil pump, being communicated with the drive cavity lubricating oil path of another oil pump into and out of hydraulic fluid port into and out of hydraulic fluid port.Two oil pumps adopt coaxial assembling and by crank-driven, compact structure is convenient to the integrally-built layout of motor.
Adopt technological scheme of the present invention, do not changing the motor profile and hanging on the basis of interface position, realized separating of hot machine and cold machine lubricant oil, help to improve engine performance, improve the working life of motor.
