As shown in Figure 3, the inlet openings 36 of the outflow opening 55 of radiator 50 and water pump 35 is connected to each other via flexible pipe 72.That is to say that an end of flexible pipe 72 is connected to the outflow opening 55 of radiator 50, the other end of flexible pipe 72 is connected to the inlet openings 36 of water pump 35.As shown in Figure 3, when observing in planimetric map, flexible pipe 72 extends from radiator 50 oblique left sides and forward, through cylinder head 24 belows, and crooked backward.As shown in Figure 2, when observing in side view, flexible pipe 72 extends forward from radiator 50, extends obliquely and forward, then obliquely and extend back.Flexible pipe 72 is formed for cooling water is sent to from radiator 50 path of water pump 35.In the present embodiment, flexible pipe 72 and water pump 35 are formed for inflow entrance 41 the second cooling water paths connected to one another with outflow opening 55 and the motor 11 of radiator 50.
As shown in Figure 1, the front surface of motor 11 and side surface are covered by body cover 48.The side surface of the side surface of containing box 18 and fuel tank 19 is also covered by body cover 48.
Now, will the structure of thermostat apparatus 80 be described.Fig. 5 is the cross-sectional view from the thermostat apparatus 80 of right-hand observation.Fig. 6 is the cross-sectional view from the thermostat apparatus 80 of forward observation.As shown in Figure 5, thermostat apparatus 80 comprises housing 82, be positioned at the thermostat 83 in the housing 82 and be positioned at cooling-water temperature sensor 84 in the housing 82 above thermostat 83, has flow path 81 in the housing 82, cooling water flow via flow path 81.
The cylindrical part 82a of housing 82 has the annular portion 95 of inwardly giving prominence to along radially.In annular portion 95, be formed centrally hole 96.The outer peripheral portion of the bottom surface of thermoelement 91 is placed on the annular portion 95.
When the temperature of the cooling water in the flow path 81 was hanged down, the stretching force of piston 93 was less than the Driving force of spring 94.As a result, thermoelement 91 is forced into annular portion 95.In this case, hole 96 is closed by thermoelement 91, mobile be stopped of cooling water in the flow path 81.On the contrary, when the temperature of the cooling water in the flow path 81 was high, along with the expansion of the element in the thermoelement 91, piston 93 stretched out against the Driving force of spring 94.As a result, as shown in Figure 7, thermoelement 91 is separated along upward direction and annular portion 95, and this opens hole 96.Therefore, cooling water flows in the flow path 81.Hereinafter, the state and the hole 96 pent states that are opened of hole 96 will be known as respectively " state that thermostat 83 is opened " and " thermostat 83 pent states ".In the above described manner, thermostat 83 is automatically regulated flowing of cooling water according to the variation of the temperature of cooling water.
As shown in Figure 5,96 sides form the bypass opening 97 of always opening in the hole.The internal diameter of bypass opening 97 is significantly less than the internal diameter in hole 96.Therefore, when thermostat 83 was opened, cooling water is basic only to flow towards exit opening 86 through via hole 96.Bypass opening 97 is not absolute necessary, and can omit when not required.
Cooling-water temperature sensor 84 is inserted into the circular hole 82d of cylindrical part 82a of housing 82 from the top.Cooling-water temperature sensor 84 only needs to be inserted among the circular hole 82d, to how cooling-water temperature sensor 84 being assembled into housing 82 is not specifically limited.For example, cooling-water temperature sensor 84 can be inserted among the circular hole 82d, and circular hole 82d makes in cylindrical part 82a.Replacedly, cooling-water temperature sensor 84 can be put in the mould, and resin can flow in the mould, so that form cylindrical part 82a, cooling-water temperature sensor 84 is integrally connected to cylindrical part 82a.In this case, in cylindrical part 82a, be not pre-formed circular hole 82d, but the part that cooling-water temperature sensor 84 is set becomes circular hole 82d.
Cooling-water temperature sensor 84 extends along cylindrical part 82a axial (downward direction among Fig. 5).The end portion 84a of cooling-water temperature sensor 84 navigates to the side of entrance opening 85.In the present embodiment, cooling-water temperature sensor 84 is positioned to thermoelement 91 coaxial.Cooling-water temperature sensor 84 is positioned at thermoelement 91 tops.Cooling-water temperature sensor 84 is positioned at spring 94 inside.Because this structure, the part of cylindrical part 82a is positioned at entrance opening 85 tops.Because cooling water flows towards exit opening 86 via hole 96 from entrance opening 85, so cooling water can be stuck in the zone that is arranged in entrance opening 85 tops among the cylindrical part 82a.But the end portion 84a of cooling-water temperature sensor 84 navigates to the side of entrance opening 85, that is, and and in the master stream of cooling water.Therefore, improve the testing precision of cooling-water temperature sensor 84.
When cooling water was ejected into the circulating path of cooling water, circulating path can be by atmospheric pollution.In the upper area in cylindrical part 82a, do not expect to be detained the air that pollutes cooling water.In order to discharge the air in the cooling water, in the discharge portion 82e of housing 82, form exhaust port 87.Form entrance 87a at an end of exhaust port 87, entrance 87a is exposed to flow path 81 and under shed.Entrance 87a is positioned on the highest possible position in the flow path 81.However, the position of entrance 87a can suitably change, as long as can discharge air.At the other end of exhaust port 87, form the outlet 87b to the side opening.The internal diameter of exhaust port 87 is less than the internal diameter of cylindrical part 82a.Entrance 87a and outlet 87b internal diameter separately be less than the internal diameter of entrance opening 85, less than the internal diameter in hole 96, and less than the internal diameter of exit opening 86.
As shown in Figure 2, in the present embodiment, thermostat apparatus 80 is positioned to have the attitude that turns forward with respect to vertical direction.Therefore, entrance 87a is positioned at than thermostat apparatus 80 and is positioned at higher position in the situation on the vertical direction.Exhaust port 87 is from entrance 87a towards exporting 87b obliquely and extending back.This structure is provided, is discharged swimmingly via exhaust port 87 so that have the air of little proportion.
As shown in Figure 2, when observing in side view, the part of thermostat apparatus 80 (more specifically, the part of cooling-water temperature sensor 84) is positioned at cylinder head 24 tops.When observing in side view, this part of thermostat apparatus 80 is positioned at the highest part top of cylinder head 24.The part of thermostat apparatus 80 navigates to the right-hand of cylinder head 24.That is to say, when in side view, observing, this partial coverage cylinder head 24 of thermostat apparatus 80.
As shown in Figure 3, the water filling part 56 of exhaust port 87 and radiator 50 is connected to each other via flexible pipe 73.That is to say that an end of flexible pipe 73 is connected to the exhaust port 87 of thermostat apparatus 80, the other end of flexible pipe 73 is connected to the water filling part 56 of radiator 50.When observing in planimetric map, flexible pipe 73 is the oblique right side and extending back roughly.More specifically, when observing in planimetric map, flexible pipe 73 extends back from the exhaust port 87 of thermostat apparatus 80, and then the oblique right side and extending back is crooked to the right, and is connected to the water filling part 56 of radiator 50.As shown in Figure 2, when observing in side view, flexible pipe 73 roughly extends back.More specifically, when observing in side view, then flexible pipe 73 extends back from the exhaust port 87 of thermostat apparatus 80 obliquely and extend back.Flexible pipe 73 is positioned at flexible pipe 71 tops.The part of flexible pipe 73 is positioned at the part top of flexible pipe 71.This part of flexible pipe 73 and this part of flexible pipe 71 overlap each other along above-below direction.The intermediate portion of the intermediate portion of flexible pipe 73 and flexible pipe 71 is by being with 74 to be secured together (referring to Fig. 3).
Fig. 8 is the structural drawing of the circulating path of cooling water.As shown in Figure 8, the cooling water that ejects from water pump 35 is directed to the cooling water path 40 the motor 11.More specifically, the cooling water that ejects from water pump 35 flow into the water jacket 31 of cylinder head 24 from inflow entrance 41, then flow in the water jacket 32 of cylinder block 23.The cooling water that has flow in the water jacket 32 flow in the water jacket 31 of cylinder head 24 again.Cooling water flows in water jacket 31 and 32 with cooled engine 11.After cooled engine 11, cooling water flows out cooling water path 40 via outflow opening 42, and flow in the thermostat apparatus 80 via entrance opening 85.
In the situation that thermostat 83 is opened, the cooling water in the thermostat apparatus 80 is directed leaving thermostat apparatus 80 through exit opening 86, and flow into via flexible pipe 71 in the upper water box 52 of radiator 50.The upper water box 52 of thermostat apparatus 80 and radiator 50 communicates with each other via flexible pipe 71, and also via flexible pipe 73 and water filling part 56 and communicate with each other.But the internal diameter of exhaust port 87 is less than the internal diameter of exit opening 86, and the internal diameter of flexible pipe 73 is less than the internal diameter of flexible pipe 71.Therefore, the flow path resistance of exhaust port 87 and flexible pipe 73 is greater than the flow path resistance of exit opening 86 and flexible pipe 71.Correspondingly, in the situation that thermostat 83 is opened, substantially only carry out from thermostat apparatus 80 to radiator 50 cooling water supplies via flexible pipe 71.
The cooling water that is fed to upper water box 52 flows into the fuse 51 from upper water box 52, and flows downward in fuse 51.At this moment, the air of the cooling water in the fuse 51 and fuse 51 flows outside is carried out heat exchange, and therefore is cooled.That is, cooling water dispels the heat.The cooling water that has flow in the fuse 51 flows in the lower header 53.Cooling water is drawn into water pump 35 via flexible pipe 72 from lower header 53.The cooling water that is sucked ejects from water pump 35 again.Then, repeat aforesaid operations.
