Abstract
A water-cooled cylinder comprises a body, a jacket, a cylinder cooling liner, and an annular launder formed by the body and the cooling liner; wherein, an annular seal base integrated with the cooling liner is installed in the inner wall of the body for sealing the annular launder, an access gallery and an outlet gallery are arranged on the body to connect with the annular launder. In the above way, the utility model has long-life service, improves the connecting strength of the jacket and the body, prevents from the dropping of the cooling liner and the jacket, and avoids the scuffing of cylinder bore and the air duct splitting resulting from the locking of the bore and the body.
Description
Technical field
The utility model relates to the parts on a kind of motorcycle engine, the cylinder block on particularly a kind of motorcycle engine.
Background technique
In the prior art, motorcycle water-cooled engine cylinder body has generally comprised cylinder shell, cylinder sleeve and cylinder heat radiation cover, surround an annular water tank between cylinder heat radiation cover and the cylinder shell inwall, by water pump with cooling water, from the annular water chamber pump in cylinder head, the motor of this structure exists following deficiency: this water cavity is deep, and the area of contact between cylinder heat radiation cover and the cylinder head inwall is less, and the join strength between them is low, cylinder sleeve is come off, in case and water dryouied, and causes piston " scuffing of cylinder bore " easily, the scorification piston, even cylinder sleeve breaks, valve link is fracture easily also, dashes and wears piston, makes the crankshaft-and-connecting-rod distortion.
Summary of the invention
The purpose of this utility model just provides a kind of water-cooled engine cylinder body of long service life, it can obviously strengthen the join strength between cylinder heat radiation cover and the cylinder casing, prevent that cylinder heat radiation cover and cylinder sleeve from coming off, avoid piston and cylinder body locking and cause piston " scuffing of cylinder bore " and valve fracture.
The purpose of this utility model is to realize by such technological scheme, it includes cylinder shell, cylinder sleeve and cylinder heat radiation cover, surround an annular water tank between cylinder heat radiation cover and the cylinder shell, it is characterized in that: the cylinder shell inwall be provided with can seal annular water tank and with the solid all-in-one-piece seal ring platform of cylinder heat radiation cover, on cylinder shell, offer the intake tunnel and the exhalant canal that communicate with annular water tank.
The utility model is in use, described annular water tank is configured to a water cooling circulation means by intake tunnel and exhalant canal with the cooling channel on water pump, the cylinder head and the Che Houping of water tank or fills with water, cylinder heat radiation cover is integral by the seal ring platform admittedly with the cylinder shell inwall, enlarged markedly the area of contact of cylinder heat radiation cover like this with cylinder block, obviously strengthened the join strength between cylinder heat radiation cover and the cylinder casing, prevent that cylinder heat radiation cover and cylinder sleeve from coming off, avoid piston and cylinder body locking and cause piston " scuffing of cylinder bore " and valve fracture.
Owing to adopted technique scheme, the utlity model has the advantage of long service life, it can obviously strengthen the join strength between cylinder heat radiation cover and the cylinder block, prevents that cylinder heat radiation cover from coming off with cylinder sleeve, avoids piston and cylinder body locking and causes piston " scuffing of cylinder bore " and valve fracture.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure: 1. cylinder shell; 2. cylinder sleeve; 3. the cylinder heat radiation is overlapped; 4. annular water tank; 5. seal ring platform; 6. intake tunnel; 7. exhalant canal.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Shown in Fig. 1 or 2, this practicality newly includes cylinder shell 1, cylinder sleeve 2 and cylinder heat radiation cover 3, surround an annular water tank 4 between cylinder heat radiation cover 3 and the cylinder shell 1, it is characterized in that: cylinder shell 1 inwall be provided with can seal annular water tank 4 and with cylinder heat radiation cover 3 solid all-in-one-piece seal ring platforms 5, on cylinder shell 1, offer the intake tunnel 6 and the exhalant canal 7 that communicate with annular water tank 4.
The utility model is in use, described annular water tank 4 is followed water pump by intake tunnel 6 and exhalant canal 7, the Che Houping of cooling channel on the cylinder head and water tank or fills with water is configured to a water cooling circulation means, cylinder heat radiation cover 3 is integral by seal ring platform 5 admittedly with cylinder shell 1 inwall, enlarged markedly the area of contact of cylinder heat radiation cover 3 like this with cylinder casing 1, obviously strengthened the join strength between cylinder heat radiation cover 3 and the cylinder casing 1, prevent that cylinder heat radiation cover 3 and cylinder sleeve 2 from coming off, avoid piston and cylinder body locking and cause piston " scuffing of cylinder bore " and valve fracture.
