Abstract
The utility model discloses a forced three-cooling engine which comprises an air cylinder body, an air cylinder head, a cooling fan and an engine oil cooler. A magnetor is arranged at one end of a crankshaft, the cooling fan is connected to a rotor of the magnetor, the air cylinder body, the air cylinder head, the cooling fan and the engine oil cooler are located in a flow guide cover, and a boiling water tank is further arranged in the flow guide cover and communicated with a cooling water sleeve arranged on the air cylinder body through a water inlet pipe and a water outlet pipe. The forced three-cooling engine is simple and compact in structure, stable in performance and capable of effectively improving the cooling effect.
Description
Technical field
The utility model relates to Motorcycle Engine Technology field, is specially a kind of pressure three cold engines.
Background technique
Traditional motorcycle engine radiating mode is divided into independent air-cooled, oil cooling and water-cooled, is wherein air-cooledly divided into again two kinds of natural air cooled and forced air coolings.But the radiation system of available engine still comes with some shortcomings, wherein most water-cooled engine need to configure the parts such as water pump at present, complex structure, and cost is higher; The motor of nature air swept type, when Vehicle Speed is slow, cooling effect is not good, and although forcedly air-cooled engine has good cooling effect, but the coaxality between cooling fan and magneto rotor is not high, reason is that existing Placement is to offer connecting groove one in the end of magneto rotor, end in the rotating shaft of cooling fan is established boss one, described boss is plugged on and in described connecting groove, realizes moment of torsion transmission, but after long-term use, in this joint, easily appearance is loosening, thereby has reduced the stability of cooling fan.
Summary of the invention
The purpose of this utility model is to provide a kind of pressure three cold engines, and it is simple and compact for structure, and stable performance can effectively improve cooling effect.
Pressure three cold engines described in the utility model, comprise cylinder block, cylinder head, cooling fan and machine oil cooler, one end at bent axle is provided with magnetogenerator, described cooling fan is connected on magneto rotor, described cylinder block, cylinder head, cooling fan and machine oil cooler are positioned at air guide sleeve, in air guide sleeve, be also provided with boiling water tank, described boiling water tank is communicated with the cooling jacket being opened in cylinder block by intake pipe and outlet pipe, cooling-air is sucked by cooling fan through the suction port of air guide sleeve, after machine oil cooler and boiling water tank, again through cylinder block and cylinder head and discharged by the air outlet of air guide sleeve.
Between the rotating shaft of described cooling fan and magneto rotor, by an inner spline sleeve, be connected.
Described intake pipe is communicated with a high position for boiling water tank, and outlet pipe is communicated with the low level of boiling water tank.
Described machine oil cooler and boiling water tank are fixed with one.
Motor described in the utility model, by the effective combination of forced air cooling, oil cooling and water-cooled, has improved cooling effect, the heat load problem while having solved motorcycle low speed, high capacity.Wherein water-cooled partly adopts boiling type water tank, utilizes the temperature difference to realize water circulation, compares existing water-cooling pattern, compact structure, and requirements of installation space is low.In addition, adopt inner spline sleeve to realize the connection of cooling fan and magneto rotor, guaranteed both with one heart.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the assembling exploded perspective view of described cooling fan and magnetogenerator.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Pressure three cold engines as shown in Figure 1, 2, comprise cylinder block 1, cylinder head 2, cooling fan 3 and machine oil cooler 4, in one end of bent axle, be provided with magnetogenerator 6, described cooling fan 3 is connected on magneto rotor 61, in the rotating shaft 31 of cooling fan and the end of magneto rotor 61, be all processed with external splines, described rotating shaft and magneto rotor insert respectively the two ends of inner spline sleeve 7, by this inner spline sleeve, are realized and are connected transmission moment of torsion.
Described cylinder block 1, cylinder head 2, cooling fan 3 and machine oil cooler 4 are positioned at air guide sleeve 8, in air guide sleeve 8, be also provided with boiling water tank 5, described boiling water tank 5 is communicated with the cooling jacket 11 being opened in cylinder block 1 by intake pipe and outlet pipe, described intake pipe is communicated with a high position for boiling water tank 5, and outlet pipe is communicated with the low level of boiling water tank 5.When engine operation, the water in cooling jacket 11 is heated, and through intake pipe, is delivered to boiling water tank 5, and the cooling water that in boiling water tank, the temperature of bottom is lower flows into cooling jacket 11 through outlet pipe and supplements, and forms cooling water flow circulation.
For making structure compacter, machine oil cooler 4 and boiling water tank 5 can be welded as a whole.Also can separate independent setting.
During work, cooling-air is sucked by cooling fan 3 through the suction port of air guide sleeve 8, flows through machine oil cooler 4 and boiling water tank 5, takes away the heat of machine oil cooler 4 and boiling water tank 5, and then flow through the fin surface on cylinder block 1 and cylinder head 2, finally by the air outlet of air guide sleeve, discharged.
