Embodiment approach

[0021] In one embodiment, the water jacket part 300 is intermittently opened in the installation cylinder 100 along the circumferential direction of the installation cylinder 100 for 360°, the reinforcement 200 includes more than one reinforcing rib, and more than one Reinforcing ribs are arranged at intervals in the jacket water portion 300 , and corresponding two sides of the reinforcing ribs are respectively fixedly matched with the cylinder inner wall 110 and the cylinder outer wall 120 . Specifically, the opening length or opening angle of the jacket water portion 300 on the installation cylinder 100 is determined according to installation requirements. For example, opening the installation cylinder 100 in a discontinuous manner can avoid separation of the cylinder inner wall 110 and the cylinder outer wall 120 . Then, the space between two adjacent water jacket holes can be processed by means of external tooling to form the required rib structure. The above-mentioned em...

Abstract

The invention relates to a motorcycle and an engine water-cooling air cylinder mechanism. The engine water-cooling air cylinder mechanism comprises an installation cylinder body and a reinforcing piece; a water sleeving part is arranged in the axial direction of the installation cylinder body from one end of the installation cylinder body to the other end of the installation cylinder body; the installation cylinder body is divided into a cylinder body inner wall and a cylinder body outer wall through the water sleeving part; the reinforcing piece is arranged in the water sleeving part; the two corresponding sides of the reinforcing piece are fixedly matched with the cylinder body inner wall and the cylinder body outer wall correspondingly; and the reinforcing piece is provided with a water passing hole used for communicating with the water sleeving part. The installation cylinder body can effectively resist side thrust generated by a piston through protection of the reinforcing piece, and therefore the installation cylinder body is prevented from deforming.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to motorcycles and engine water-cooled cylinder mechanisms. Background technique [0002] The engine water-cooled cylinder includes a closed water jacket cylinder block and an open water jacket cylinder block. For example: when the open water jacket cylinder is produced, it will be produced by die casting. When the water jacket of the cylinder body is processed, there will be an annular gap between the inner wall of the cylinder body and the outside of the cylinder body. At this time, when the cylinder body and the piston are in transmission, the thrust generated by the piston will easily cause the deformation of the inner wall of the cylinder body, thus making the cylinder body It is prone to problems such as large amount of blow-by gas, large oil consumption, and abnormal noise. Contents of the invention [0003] Based on this, it is necessary to provide an engine water-cooled...
