Cylinder body and cylinder liner integrated into one piece constitute integral cylinder structure promptly, make the cylinder liner constitute the wet cylinder liner, circulation water cavity substantially closed is only at the cylinder body upper surface communicating delivery port of water cavity that is equipped with and circulates. The delivery port is one. The utility model discloses the cylinder bore deformation is little, can reduce the piston scuffing of cylinder bore condition. Heat transfer efficiency is high between cylinder liner and the cooling water, and it is many that the circulating water absorbs the heat, and the cooling effect is good, is favorable to reducing engine temperature.
Description
Technical field
This utility model relates to motorcycle engine, particularly relates to a kind of integrated water-cooling engine of motorcycle cylinder body assembly, belongs to Motorcycle Engine Technology field.
Background technology
Cylinder block is the main body of electromotor, and its working condition is the most severe.Drastically change and the strong friction of piston movement of pressure and temperature in its combustion process to be born.Therefore, cylinder block should have following performance: has enough strength and stiffness, deforms little, it is ensured that each moving parts position is correct, works well, and vibration noise is little；There is good cooling performance, it is possible to quickly take away heat.Water-cooled is the type of cooling that electromotor is common.Being machined with circulating water cavity around the cylinder block of water-cooled engine, circulating water cavity communicates with cylinder head, and cooling water constantly circulates in water cavity, takes away partial heat, complete machine is risen cooling effect.Fig. 1 is conventional motorcycle engine cylinder block assembly structure schematic diagram, and it is split-type structural, external cylinders 1 and internal cylinder sleeve 2 combine, and cylinder sleeve 2 is cast iron materials, and cylinder body 1 is aluminium alloy.Being provided with circulating water cavity 3 in cylinder body 1, circulating water cavity 3 is ring-type, and its upper surface is uncovered, and this cylinder sleeve 2 is dry cylinder liner.Existing cooling engine for motor cycle water cylinder body assembly has the disadvantage that 1, due to cylinder body different with cylinder jacket material, both thermal deformations are big, thus cause cylinder-bore distortion big, pull-cylinder phenomena easily occur.2, owing to for dry cylinder liner, heat transfer efficiency is poor between cylinder sleeve and cooling water, it is unfavorable for reduction engine temperature.
Utility model content
For deficiencies of the prior art, the purpose of this utility model is to provide a kind of good cooling results, can reduce the integrated water-cooling engine of motorcycle cylinder body assembly of pull-cylinder phenomena.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of integrated water-cooling engine of motorcycle cylinder body assembly, including cylinder body and cylinder sleeve, is provided with circulating water cavity in cylinder body, is provided with the water inlet tap communicated with circulating water cavity at side of cylinder block.Described cylinder body and cylinder sleeve are one-body molded, i.e. constitute combined cylinder-block-crankcase unit structure, make cylinder sleeve constitute wet cylinder liner；Described circulating water cavity integrally closed, is only provided with, at cylinder body upper surface, the outlet communicated with circulating water cavity.Outlet is one.
Further, being provided with some fabrication holes communicated with circulating water cavity at side of cylinder block, remove for core after cylinder body molding, described fabrication hole is closed by plug, makes circulating water cavity integrally closed.
Described plug screw thread is screwed on fabrication hole so that installation and removal are convenient.
Described cylinder body and steel jacket material are middle phosphorus cast iron, and plug is ferrous materials.
Compared to existing technology, this utility model has the advantages that
1) all-in-one-piece cylinder block assembly cylinder-bore distortion is little, it is possible to reduce piston scraping situation.
2) integral totally enclosed cylinder body belongs to typical case's wet cylinder liner, and for traditional dry cylinder liner cylinder block, between cylinder sleeve and cooling water, heat transfer efficiency is high, and it is many that recirculated water absorbs heat, and good cooling results advantageously reduces engine temperature.
3) totally-enclosed cylinder block cyclic water channel volume is big, and recirculated water stores many, absorbs heat many, the most beneficially engine radiating.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
See Fig. 2-Fig. 6, it can be seen that this utility model integrated water-cooling engine of motorcycle cylinder body assembly from figure, including cylinder body 1 and cylinder sleeve 2, in cylinder body 1, be provided with circulating water cavity 3, be provided with the water inlet tap 4 communicated with circulating water cavity 3 in cylinder body 1 side.Described cylinder body 1 and cylinder sleeve 2 are one-body molded, i.e. constitute combined cylinder-block-crankcase unit structure, make cylinder sleeve constitute wet cylinder liner.This utility model uses all-in-one-piece cylinder block assembly, and cylinder-bore 7 deforms little, it is possible to reduce piston scraping situation.The most integral totally enclosed cylinder body belongs to typical case's wet cylinder liner, and for traditional dry cylinder liner cylinder block, between cylinder sleeve and cooling water, heat transfer efficiency is high, and it is many that recirculated water absorbs heat, and good cooling results advantageously reduces engine temperature.Described circulating water cavity 3 integrally closed, is only provided with, at cylinder body 1 upper surface, the outlet 5 communicated with circulating water cavity 3.During actual installation, can arrange sealing gasket between cylinder block and cylinder head, the position corresponding with outlet at sealing gasket is provided with through hole, makes outlet communicate with cylinder head by this through hole.Diagram embodiment outlet is one.
In order to form totally enclosed circulating water cavity, further, being provided with some fabrication holes communicated with circulating water cavity in cylinder body 1 side, the core in circulating water cavity is removed after cylinder body molding by this fabrication hole, i.e. core in circulating water cavity is discharged by fabrication hole after smashing to pieces；By plug 6, fabrication hole is closed the most again, make circulating water cavity integral full-closed.Totally-enclosed cylinder block cyclic water channel volume is big, and recirculated water stores many, absorbs heat many, the most beneficially engine radiating.
Described plug 6 screw thread is screwed on fabrication hole so that installation and removal are convenient.
Described cylinder body 1 and cylinder sleeve 2 material are middle phosphorus cast iron, and plug 6 is ferrous materials.
Above-described embodiment of the present utility model is only for this utility model example is described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, change and the variation of other multi-forms can also be made on the basis of the above description.Here cannot all of embodiment be given exhaustive.Every belong to obvious change that the technical solution of the utility model amplified out or the variation row still in protection domain of the present utility model.
