Abstract
The utility model discloses an internal combustion engine air cylinder which comprises a piston, a connecting rod, a cylinder block, an oil pan, a gear chamber and a flywheel housing. The utility model is characterized in that the cylinder body, the oil pan, the gear chamber and the flywheel housing constitute a whole structure. The utility model has the advantages of low cost, stable structure and long life-span.
Description
Technical field
The utility model relates to the improvement of Structure of Internal-Combustion Engine.
Background technique
In the existing internal-combustion engine technology, the cylinder block in the cylinder, oil sump, gear chamber, flywheel casing are individual components or combiner.The form of parts combination has cylinder block and gear chamber combination; The combination of cylinder block and flywheel casing is arranged; The combination of cylinder block and oil sump is arranged.In order to guarantee the normal operation of cylinder, each parts or assembly must guarantee intensity and rigidity separately, and mutual orientation type and assembly structure must be arranged.The locating face of each parts or assembly must precision machining, can guarantee the assembly precision of cylinder, with fit it is combined then, finishes the allomeric function of internal-combustion engine.Therefore the processing cost of cylinder is higher, and Location accuracy is poor, and bulk strength is low, poor rigidity.In addition, the material that is used to assemble supporting surface is repetition and waste also, causes the volume of cylinder, weight bigger.
Summary of the invention
The utility model is to overcome the deficiencies in the prior art, and the cylinder of internal-combustion engine of the firm and long service life of a kind of with low cost, structure is provided.
The utility model is achieved in that a kind of cylinder of internal-combustion engine, comprises piston, connecting rod, cylinder block, oil sump, gear chamber and flywheel casing, it is characterized in that: described cylinder block, oil sump, gear chamber and flywheel casing are an overall structure.
The utility model improves traditional cylinder of internal-combustion engine, with by cylinder block, oil sump, gear chamber, being combined as a whole of flywheel casing entire combination, replaces existing each individual components or combiner.By changing the Placement of cylinder block, oil sump, gear chamber and flywheel casing, improve its bulk strength and rigidity, need not to carry out the processing of assembling and positioning face, improve Location accuracy, and saved processing cost.In addition, all-in-one-piece structure can be saved material and the mounting structure between each parts mating face, reduces the volume and the weight of cylinder of internal-combustion engine.
Description of drawings
Fig. 1 is the structural representation of the utility model cylinder of internal-combustion engine.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
According to shown in Figure 1, cylinder of internal-combustion engine of the present utility model comprises piston, connecting rod, cylinder block 1, gear chamber 2, oil sump 3 and flywheel casing 4.For bulk strength and the rigidity that improves cylinder of internal-combustion engine, cylinder block 1, oil sump 3, gear chamber 2 and flywheel casing 4 are monolithic construction.Monolithic construction can be cylinder block 1, oil sump 3, gear chamber 2 and flywheel casing 4 time processing moulding when the casting cylinder of internal-combustion engine.The cylinder of internal-combustion engine of this structure has saved assembling and positioning structure and the machining face between cylinder block 1, oil sump 3, gear chamber 2 and the flywheel casing 4, make cylinder of internal-combustion engine, oil sump, gear chamber and flywheel casing need not assemble mechanism and assembling supporting surface, so reduced the volume and the weight of cylinder of internal-combustion engine.Because the assembling and positioning structure and the machining face of cylinder of internal-combustion engine all are removed, and need not to process independently locating face and mating face, therefore reduced processing cost.Cylinder block 1, oil sump 3, gear chamber 2 and flywheel casing 4 are formed in one, and the relative position error between the parts is irrelevant with assembling, has improved the Location accuracy between the parts effectively.Therefore, need not any assembling between each parts of integrated type cylinder of internal-combustion engine and connect, its compact structure, cost is low, bulk strength height, good rigidly, long service life.
