Description
Technical field
This utility model is related to engine components field, and in particular to a kind of leakproof wet type engine cylinder of install convenient
Set.
Background technology
The structure of cylinder has been known, and its form substantially has three kinds：Depletion of QI cylinder sleeve type cylinder, wet type cylinder and dry type gas
Cylinder.
The body of depletion of QI cylinder sleeve type cylinder does not inlay the body of any cylinder jacket, and cylinder is directly processed on body,
Advantage can be shortening bore spacing, reduce cabinet size and quality.But it is relatively costly.
The cylinder jacket outer peripheral face of wet type cylinder and coolant directly contact, isolate coolant and cylinder work by cylinder sleeve completely
Making room, radial positioning being realized using upper and lower locating ring band, axially position is propped up by cylinder jacket upper flange is corresponding with the top of body
Bearing surface coordinates to be realized.The advantage of wet liner is the water jacket being not closed in cylinder block, is easily cast, and wet liner leads to
Chang Bihou can accomplish 5-8mm, conducting heat, cooling effect also preferably, Temperature Distribution is than on the basis of more uniform, it may have enough
Intensity, and repair convenient, it is not necessary to which electromotor is pulled down with regard to replaceable cylinder jacket from automobile.Have the disadvantage that integral rigidity is poor,
Easily leak.
The cylinder jacket of dry cylinder is not contacted with coolant, and wall thickness is 2-3mm, outer surface and cylinder jacket seat bearing bore inner surface
Must polish, with ensure necessary bit-type precision and be easy to dismounting.In order to obtain enough real contact areas and between cylinder body,
Ensure that the radiating of cylinder sleeve and the inner surface of positioning, the outer surface of cylinder sleeve and the cylinder block bearing bore coordinated with which have certain processing
Precision, the two typically adopts interference fit.The advantage of dry liner is that body rigidity is big, and bore spacing is little, light weight, plus
Work process is simple.Have the disadvantage that heat transfer is poor, temperature distributing disproportionation is even, is susceptible to local deformation.
The application of wet type cylinder is wide, but Jing often occurs installing inconvenience, installs not enough essence during actual installation
Really, impact installation effectiveness and situation about normally using, and in actual use, it may appear that coolant is by cylinder sleeve seat and cylinder
Situation about leaking at set gap, practicality have much room for improvement.
In consideration of it, inventor is furtherd investigate to the problems referred to above, there is then this case to produce.
