Description
Technical field
The utility model relates to a kind of limit lid of water-cooled internal combustion engine crankcase, is specifically related to a kind of limit lid that is provided with the water-cooled internal combustion engine crankcase of oil leab.
Background technique
At present, the water-cooled internal combustion engine for the limit that water pump is arranged in crankcase covers covers on the limit usually and will arrange oil leab and water channel simultaneously, and water channel is respectively to become autonomous system and mutual noninterference with oil duct, and cooling liquid does not directly produce cooling action to lubricant oil.And the setting of oil duct is generally the oil inlet hole on limit lid and end face that crankcase body combines, an end that is arranged on the limit lid oil input channel in the lid shell body wall of limit is communicated with oil inlet hole, the other end is communicated with the chamber wall that is arranged on the filter thin oil installation cavity that the limit covers, centre exit from the filter thin oil installation cavity connects some the function oil ducts that are arranged in the lid shell body wall of limit again, leads to the position that needs lubricated gas engine part respectively; The oil inlet hole that lubricant oil is covered on the end face that combines by crankcase body and limit by oil pump enters, chamber wall from the filter thin oil installation cavity flows out again, after filter thin oil filters, enter each bar function oil duct from the centre exit shunting of filter thin oil installation cavity, arrive the position that needs lubricated gas engine part, or directly is communicated with function oil duct in being arranged on limit lid shell body wall from limit lid oil input channel, lead to the position of the gas engine part that need lubricate respectively; Its deficiency is: for some high-revolving reinforced internal-combustion engine, as motorcycle engine, cooling to lubricant oil is but very important, and as this generic request compact structure of motorcycle engine and the function oil duct internal-combustion engine of relative complex again, existing oil leab is arranged the requirement that can not satisfy function.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and can effectively reduce the limit lid of the water-cooled internal combustion engine crankcase of internal combustion engine lubrication oil temperature.
The purpose of this utility model is achieved in that a kind of limit lid of water-cooled internal combustion engine crankcase, comprise the oil inlet hole that is arranged on limit lid and the end face that crankcase combines, be arranged in the lid shell body wall of limit, the limit lid oil input channel that one end is communicated with oil inlet hole, be arranged on the filter thin oil installation cavity that the limit covers, be arranged in the lid shell body wall of limit, one end is communicated with the centre exit of filter thin oil installation cavity, some the function oil ducts that the other end is communicated with the position that needs lubricated gas engine part, and be arranged on the lid outside, limit the water pump installation cavity and with the water pump cover of the supporting setting of water pump installation cavity, it is characterized in that: setting is connected between the chamber wall of described limit lid oil input channel and described filter thin oil installation cavity cooling oil duct and transition oil duct.
Described cooling oil duct is cooperated by circular groove on the planar annular that is arranged on described water pump installation cavity with described water pump cover engages and described water pump cover and forms, and a side of described circular groove is covered oil input channel with described limit and is communicated with; Described transition oil duct is arranged in the lid shell body wall of limit, and its two ends are communicated with the described circular groove opposite side of described cooling oil duct and the chamber wall of described filter thin oil installation cavity respectively.
Be arranged on the circular groove that described circular groove on above-mentioned water pump installation cavity and the planar annular that described water pump cover engages can be sealing, also can be untight circular groove, can require according to cooling to determine lubricant oil.
The described function oil duct of 2 connections can be set at the described centre exit place of said engine oil secondary filter installation cavity, and wherein the outlet end of a function oil duct is positioned at position, clutch place, and the outlet end of another function oil duct is positioned at position, crank-connecting rod place.
The limit lid of the water-cooled internal combustion engine crankcase that the utility model provides, lubricant oil arrives the cooling oil duct that water pump cover and limit cover the junction plane place of water pump installation cavity from the oil inlet hole and the Bian Gai oil input channel of oil pump oil road by limit lid and the junction plane of crankcase body, and lubricant oil enters other function oil ducts after through the local cooling of the cooling liquid of circulation water pump and participates in lubricated the circulation.Water pump cover and limit cover the cooling oil duct of the junction plane of water pump installation cavity and by water pump cover the back sealing are installed.
Therefore, the limit of the water-cooled internal combustion engine crankcase that the utility model provides lid, simple and reasonable, good manufacturability has effectively reduced lubricating oil temperature, has solved the Layout Problem that complicated oil duct is covered on water-cooled internal combustion engine crankcase limit simultaneously.
