Abstract
The utility model relates to a motorcycle liquid cooling engine. A liquid cooling cavity is directly arranged on the outer wall of a cylinder body, and an inlet liquid filling joint and an outlet liquid filling joint are arranged on an outer shell of the liquid cooling cavity. Two joints are respectively communicated with cold and hot liquid outlets and cold and hot liquid inlets of a radiator installed on a motorcycle frame by pipelines to form a closed cycle liquid cooling system on the outer wall of the cylinder body. The motorcycle liquid cooling engine has simple and easy operation, good cooling effect, stable performance, and long service life. Relative each technical index is improved.
Description
The utility model relates to motorcycle engine cooling technology field.
At present, the two-wheeled of numerous middle or small discharge capacities (50-250cc) and motor tricycle all adopt nature air swept type petrol engine, this engine cooling speed slowly, especially when the long-time big load of motorcycle in the summer of sweltering heat travels or climbs for a long time that particularly climb very steep slopes travels, will occur reducing even the motionless phenomenon of walking because of the bad engine overheat of cooling effect, oil consumption increase, power.
The purpose of this utility model is the deficiency that overcomes above-mentioned motorcycle engine, and a kind of good cooling results, stable performance, simple and easy to do, widely applicable motorcycle liquid-cooled engine are provided.
The purpose of this utility model realizes by following proposal.
Producing the position at the thermal source of motorcycle engine is engine cylinder＜firing chamber〉former radiating fin place directly is provided with roomy liquid cooling chamber on the outer wall, cylinder block outer wall is the inwall in liquid cooling chamber, between two attachment faces the liquid cooling chamber enclosure that section is shape is set up and down in cylinder block, the ring cylinder block forms one and contains the liquid air chamber, no matter vertical still horizontal engine, two joints up and down all are set on the shell cavity vertical line, upper connection is the hydrothermal solution liquid outlet, lower contact is cold liquid liquid entering hole, two joints are communicated with radiator liquid in-out joint on being installed in vehicle frame with pipeline, form the closed-circuit liquid-cooling system of cylinder block outer wall, be full of the good and good non freezing solution body that flows of conduction in liquid cooling chamber and the radiator, the circulation one of cooling liquid be can be under discrepancy in elevation effect and action of thermal difference automatic cycle, the 2nd, can on motorcycle, set up a water pump and be communicated with pressurizing circulation with the liquid pipe, being provided with of cooling sap cavity can be with the whole die casting of cylinder block, can weld, can be that two and half shells are formed by combining as screw and rivet with link, radiating fin on can the retained gas outer wall of cylinder block in cooling chamber, also can not keep radiating fin, the utility model is fit to the transformation of the motorcycle air cooling engine cylinder block of all models and discharge capacity, and can exchange with the same model air cooled cylinder.
The utility model is owing to be to be provided with the liquid cooling chamber on cylinder block (firing chamber) outer wall at the thermal source generation position of motor directly, cooling liquid is cooled off the cylinder block outer wall comprehensive engagement, and by conduction cooling crankcase and cylinder head, simple and easy to do, widely applicable, good cooling results makes the stable performance of motorcycle engine, prolong working life, and relevant every technical order is improved.
Below in conjunction with accompanying drawing the utility model is further specified:
Accompanying drawing is a motorcycle liquid-cooled engine block structure schematic representation.
As shown in the figure: realize, on cooling chamber body case 9, be provided with joint 2 and 3 and communicate by shape shell 9 with cooling chamber 8 in the formation that liquid cooling chamber 8, liquid cooling chamber are set between attachment face 5 and the following attachment face 1 on the outer wall 7 of cylinder block firing chamber 4, joint 2 and 3 respectively with the cold liquid liquid outlet of radiator and the hydrothermal solution liquid entering hole pipeline connection that are installed on the frame of motorcycle, form the closed-circuit liquid-cooling system of cylinder block outer wall, cylinder block is to fit together the formation engine assembly by mounting hole 6 usefulness screw rods and crankcase and cylinder head.
