Description
Technical field
The present invention relates to technical field of motorcycles, in particular to a kind of motorcycle cooling system and engine cool side
Method.
Background technology
With the popularization of family car, gradually instead of conventional motorcycle as the status of walking-replacing tool, and on the other hand,
Increasing people shows the demand of more individual character to motorcycle, and therefore, the high-end motorcycle of increasing huge discharge is gradually
Come out.
It is known that the bigger motorcycle of discharge capacity, power is also bigger, and the bigger acting of power is more, more explanations of doing work
It is also more that electromotor heat energy is converted into mechanical energy, and meanwhile, the heat that electromotor produces is also more, needs to cool down electromotor
Temperature is particularly important with ensureing stable output.However, conventional engines are all using natural air cooled, pressure wind
The types of cooling such as cold, oil cooling, water-cooled.Comparatively speaking, in traditional type of cooling, water-cooled is that effect is best, as shown in figure 1, existing
Some cooling systems include being driven the water pump 1 of rotation by engine crankshaft, and this water pump is mechanical water pump, the outlet of mechanical water pump
It is sequentially connected engine cylinder-body water channel, cylinder cap water channel and temperature-conserving valve 4, an outlet of described temperature-conserving valve 4 is by pipeline even
It is connected to the water inlet of described mechanical water pump, form cooling water small-size circulating；Another outlet is connected to radiator group by pipeline
Part 2, the outlet of heat sink assembly 2 is connected to the water inlet of described mechanical water pump, becomes cooling water systemic circulation.During work, once
Engine start, with regard to driving mechanical pump operation, coolant cools down to electromotor through partial circulating, when engine cylinder-body
When temperature rises to the first setting value, such as 75 degree, temperature-conserving valve is opened, and coolant passes through temperature-conserving valve inflow radiator assembly, leads to
Cross natural wind and improve radiating efficiency.When center housing temperature further rises to the second setting value, such as 91 degree, on heat sink assembly
Fan start working, until center housing temperature be less than the 3rd arranges value, when such as 87 degree, fan quits work.So circulate past
Again it is ensured that electromotor works in most suitable temperature range, to improve efficiency of combustion.
But, in above-mentioned cooling system, there are two circulations of size so that the complicated integral structure of cooling system, inconvenient
Arrangement in cooling line.Meanwhile, after engine start, coolant is carried out to the cylinder body of electromotor and cylinder cap through partial circulating
Cooling, and mechanical water pump identical with the rotating speed of engine crankshaft so that the flow velocity in partial circulating higher so that the temperature rise of electromotor
Less, extend the time that electromotor works from cold to heat engine, be unfavorable for fully burning, increase the pollutant of discharge, reduce
Engine power.
