Abstract
The invention discloses a water inlet pipe joint mounting structure of a motorcycle water-cooled engine cylinder body, which comprises a cylinder body provided with a water jacket and a water inlet pipe joint, wherein a boss is arranged at the position of the water inlet pipe joint mounted on the cylinder body, a water inlet hole formed by casting is formed in the boss and communicated with the water jacket, and a threaded hole is formed in the end face of the boss; the water inlet pipe joint is provided with a flange plate, the flange plate is provided with a through hole corresponding to the threaded hole, the joint surface of the flange plate of the water inlet pipe joint corresponds to the end surface of the boss and is fixed on the boss of the cylinder body through screw connection, and a sealing element is arranged between the joint surface of the flange plate of the water inlet pipe joint and the end surface of the boss. The water leakage prevention device can effectively prevent the water leakage phenomenon between the water inlet pipe joint and the cylinder body and can also eliminate the problem that the inner wall of the water jacket of the cylinder body is damaged.
Description
Technical field
The present invention relates to cooling engine for motor cycle water, particularly a kind of motorcycle water-cooled engine cylinder body admitting pipe joint mounting structure.
Background technique
The assembling of existing motorcycle water-cooled engine cylinder body admitting pipe joint, normally on water-cooled engine cylinder body, process interference press mounting hole or tapped hole, then the metallic pipe coupling interference is press-fited or scyewed joint is fixed in the hole that processes on the cylinder block as water intake by machining.This fill hose joint adopt interference to press-fit or screw-thread fit on cylinder block, there is some difference because of high hot caused thermal expansion that the material of the material of cylinder block and fill hose joint produces when the engine operation, cause being easy to generate the slit between fill hose joint and the cylinder block, in use be easier to occur water leakage phenomenon; And, on cylinder block during processing interference press mounting hole or tapped hole, drill bit be easy to the to damage inwall of cylinder block water jacket, the difficulty of its processing is bigger, causes this hole to be difficult for processing; It is also bigger that the interference of fill hose joint simultaneously press-fits difficulty.
Summary of the invention
The objective of the invention is problem at the prior art existence, a kind of motorcycle water-cooled engine cylinder body admitting pipe joint mounting structure is provided, the water leakage phenomenon between fill hose joint and the cylinder block can either be effectively prevented, the problem that cylinder block water jacket inwall is damaged can be eliminated again.
The object of the present invention is achieved like this: comprise the cylinder block, the fill hose joint that are provided with water jacket, the place that described cylinder block is installed into water pipe adapter is provided with boss, and the water inlet that has casting on the boss is communicated with water jacket, and raised head face is provided with tapped hole; Described fill hose joint has a flange plate, flange plate is provided with the through hole of corresponding tapped hole, the mating face of the flange plate of fill hose joint is corresponding with raised head face, is fastened on the cylinder block boss by screw, between the flange plate mating face of fill hose joint and the raised head face Sealing is set.
Owing to adopted such scheme, the place that is installed into water pipe adapter at cylinder block is provided with boss, the water inlet that has casting on the boss is communicated with water jacket, make water inlet on the cylinder block when cast block and cylinder block and the moulding of water jacket integrally casting like this, eliminated and on cylinder block, adopted machining to creep into the problem that the water hole injures the water jacket inwall.Tapped hole is set on raised head face,, makes tapped hole that enough degree of depth be arranged, guarantee that screw can have enough length of thread engagement because of boss has increased cylinder body wall thickness herein.Described fill hose joint has a flange plate, and flange plate is provided with the through hole of corresponding tapped hole, and fill hose joint can be connected by flange with the cylinder block boss, has reduced the assembling difficulty of fill hose joint and cylinder block like this, also is convenient to maintenance.Between fill hose joint and cylinder block boss, Sealing is set, can guarantees the sealing effect of joint, water leakage phenomenon can not occur in the using process.And, because fill hose joint adopts flange to be connected with cylinder block, only need guarantee during its machining that the mating face is smooth just passable, its machining difficulty also reduces relatively.
The invention will be further described below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is an assembly structure figure of the present invention;
Fig. 2 is the schematic representation of fill hose joint of the present invention.
In the accompanying drawing, 1 is cylinder block, and 2 is the water inlet, and 3 is water jacket, and 4 is tapped hole, and 5 is flange plate, and 6 is through hole, and 7 is fill hose joint, and 8 is circular groove, and 9 is Sealing, and 10 is boss.
Embodiment
Referring to Fig. 1, Fig. 2, be a kind of embodiment of motorcycle water-cooled engine cylinder body admitting pipe joint mounting structure.Comprise the cylinder block 1, fill hose joint 7, the Sealing 9 that are provided with water jacket 3.Described cylinder block 1 is installed into the place and cylinder block integrally casting moulding one boss 10 of water pipe adapter 7, the water inlet 2 that has casting on the boss 10 is communicated with water jacket 3, the end face of boss 10 is provided with 2～4 tapped holes 4, these tapped holes 4 be distributed in water inlet 2 around, the end face of the boss 10 of present embodiment is set to be similar to the structure of rhombus, so adopt two tapped holes to be symmetrically distributed in the both sides of water inlet 2.Described fill hose joint 7 has a flange plate 5, and flange plate 5 is structure as a whole with fill hose joint 7.Flange plate 5 is provided with two through holes 6 of corresponding tapped hole 4, and the mating face of the flange plate 5 of fill hose joint 7 is set to be similar to the structure of rhombus, the mating face of flange plate 5 corresponding with boss 10 end faces.Sealing 9 is set between flange plate 5 mating faces of fill hose joint and boss 10 end faces realizes sealing, the Sealing 9 of present embodiment adopts the papery sealing gasket.Screw (not shown) passes through hole 6 and the papery sealing gasket on fill hose joint 7 flange plate, is threaded with cylinder block boss 10 end face upper screwed holes 4, fill hose joint 7 is fastenedly connected be fixed on the cylinder block boss 10.
The present invention not only is confined to the foregoing description, can also be provided with circular groove 8 on the mating face of the flange plate 5 of fill hose joint, rubber seal (not shown) is set in circular groove 8 realizes sealing.Perhaps on the end face of the boss 10 of cylinder block 1, circular groove is set, rubber seal figure is set in circular groove realizes sealing (not shown).
When the present invention assembles, Sealing is located between fill hose joint and the cylinder block boss, insert with the screw of M6 through hole, pass the via hole that Sealing is provided with, the tapped hole screw-thread fit that is provided with the cylinder block boss from the flange plate of fill hose joint, formation is fastenedly connected, be connected firmly, good airproof performance is difficult for taking place water leakage phenomenon, it is also extremely convenient to install, dismantle, and is convenient to safeguard.
