Description
Technical Field
The utility model belongs to the technical field of motorcycle engine cylinder body, specifically be an engine cylinder body with lubricating structure.
Background
In the current motorcycle engine, the lubricating modes of an engine cylinder hole, a piston and a piston pin are two types of forced spray and splash lubrication generally. The forced spraying is generally used for a high-end motorcycle engine with a crankshaft in a bearing bush structure, and the price is relatively high. Most motorcycle engines are mainly lubricated by splashing, and the oil thrown out by the big end of the crankshaft connecting rod of the engine lubricates a cylinder hole, a piston and a piston pin. However, under certain working conditions, cylinder pulling caused by insufficient lubrication of a cylinder hole and a piston is easy to occur, and the phenomenon that the piston pin is locked due to insufficient lubrication of the piston pin, the temperature of engine oil is high and the like is caused.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an engine cylinder body with lubricating structure to the problem of drawing the jar appears easily in the engine among the solution prior art.
In order to achieve the purpose, the utility model discloses a basic scheme provides an engine cylinder body with lubricating structure, including the cylinder body, be provided with the lubricating oil duct on the cylinder body, be provided with the cylinder hole on the cylinder body, be provided with the nozzle opening on the cylinder body, nozzle opening and lubricating oil duct intercommunication, the one end of nozzle opening is just to piston bottom dead center position department piston pin place region in the cylinder hole.
The principle and the beneficial effect of the basic scheme are as follows: the piston bottom dead center refers to the limit position of the piston close to the crankshaft in the cylinder hole. Lubricating oil in the lubricating oil duct directly sprays piston lower dead center position department in the cylinder hole through the nozzle opening, and when the piston moved in the cylinder hole, nozzle opening spun lubricating oil can spray on piston pin and piston to lubricate and cool piston pin, piston, cylinder hole, thereby compensatied cylinder hole, piston and piston pin and adopted the connecting rod major part lubricated not enough that splashes, avoided appearing drawing jar and piston pin locking's problem.
Further, one end of the oil injection hole, which is far away from the cylinder hole, penetrates through the cylinder body. By adopting the arrangement, the oil injection hole can be conveniently and directly operated from the outside of the cylinder body when being processed, thereby reducing the processing difficulty of the oil injection hole and being beneficial to reducing the cost.
Furthermore, one end of the oil injection hole, which is far away from the cylinder hole, is statically connected with a plug structure. By adopting the arrangement, the lubricating oil in the oil injection hole can be sprayed out from one end only, and the cooling effect is ensured.
Further, the plug structure comprises a bolt, and the bolt is in threaded sealing connection with the oil injection hole. By adopting the arrangement, the plug structure is convenient to disassemble and assemble.
Drawings
FIG. 1 is a schematic view of an embodiment of an engine block with a lubricating structure according to the present invention;
fig. 2 is a sectional view taken along line a-a of fig. 1.
Detailed Description
The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: the cylinder body 1, the cylinder hole 2, the lubricating oil channel 3, the oil spray hole 4, the bolt 5, the copper pad 6, the piston pin 7 and the piston 8.
The embodiment is basically as shown in the attached figures 1 and 2: an engine cylinder body with a lubricating structure comprises a cylinder body 1, a cylinder hole 2 for a piston 8 to move is formed in the cylinder body 1, and a lubricating oil channel 3 for lubricating oil to flow is formed in the cylinder body 1. An oil injection hole 4 communicated with the lubricating oil channel 3 is formed in the cylinder body 1, and one end of the oil injection hole 4 is opposite to the area of a piston pin 7 at the position of the lower dead point of a piston 8 in the cylinder hole 2. The oil spout 4 is straight hole, and the one end that jar hole 2 was kept away from to oil spout 4 runs through cylinder body 1. One end that jar hole 2 was kept away from to nozzle opening 4 is provided with the end cap structure, and in this embodiment, the end cap structure includes bolt 5, and the cover is equipped with sealed copper pad 6 on the bolt 5, and bolt 5 and nozzle opening 4 threaded connection to make sealed copper pad 6 seal the gap between bolt 5 and the nozzle opening 4.
The specific implementation process is as follows: when the engine runs, lubricating oil in the lubricating oil channel 3 is sprayed into the cylinder hole 2 through the oil spraying hole 4, and when the piston 8 runs to the position of the lower dead point, the lubricating oil is sprayed onto the piston 8 and the piston pin 7, so that the cylinder hole, the piston 8 and the piston pin 7 are lubricated and cooled, the defect of splash lubrication is overcome, the cylinder scuffing phenomenon and the piston pin 7 locking phenomenon are avoided, and the performance of the engine is improved.
The above description is only an example of the present invention, and the common general knowledge of the known specific structures and characteristics of the embodiments is not described herein. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
