The temperature sensor (4) of water pipe (5) both sides is used for the temperature for measuring cooling water in cooling water pipe (5), afterwards by this information transmission
Electron control unit (1), electronic control unit (1) can judge the dynamic temperature for whether being more than setting of this temperature after being connected to information
Angle value;The temperature sensor (4) for being arranged in outer barrel of absorber wall (15) both sides is used for the temperature for measuring shock absorber body (8), so
Afterwards by this information transmission electron control unit (1);The frequency that electronic control unit (1) transmits according to vibration frequency sensor (11)
Rate signal controls the opening and closing of water pump;Electronic control unit (1) is according to vibration frequency sensor (11) and TEMP
The information that device (4) transmits controls the startup and closing of electric fan (6);The Electronic Control list after water pump (3) is stopped
First (1) controls electric fan (6) rotary head function according to the information for temperature sensor (4) transmission for being distributed in cooling water pipe both sides
Opening and closing.
Described electric fan (6) is when the vibration frequency that vibration frequency sensor (11) is measured is more than setting value, electronics
Control unit (1) control electric fan (6) is opened;Electric fan (6) is more than setting value in the temperature that temperature sensor (4) is measured
When, electronic control unit (1) control electric fan (6) is opened;After water pump (3) is stopped, electronic control unit (1)
The temperature measured according to temperature sensor (4) controls the opening and closing of electric fan (6), while electric fan (6) basis
It is distributed in the situation that the temperature averages that the temperature sensors (4) of cooling water pipe both sides is measured are more than setting value, Electronic Control list
The rotary head function of first (1) control electric fan (6) is opened.This design can be under shock absorber heating serious situation by water cooling
Reasonably combined radiating with air-cooled two kinds of radiating modes, radiating effect is obvious;It can also be generated heat not in shock absorber body (8)
It is that very serious situation gets off to be used alone wind-cooling heat dissipating, while (rotary head function is also opened) can be with when electric fan (6) is run
Cooling water and cooled plate (14) are cooled more quickly, is so more beneficial for water cooling, both, which combine to bring out the best in each other, dissipates whole system
Thermal effect is more efficient, and this designs the life-span that can also extend cooling system.
The vibration frequency that described vibration frequency sensor (11) is measured then illustrates vibration damping if greater than the frequency values of setting
The internal working environment of device body (8) is severe, and heat situation is serious, and is possible to produce the situation of overheat;Now Electronic Control
Unit (1) control water pump (3) and electric fan (6) are started working;The temperature for being distributed in outer barrel of absorber wall (15) and both sides passes
Sensor (4) measures the temperature of the shock absorber body (8) after radiating, afterwards by this feedback of the information electron control unit (1), such as
The temperature averages that fruit is distributed in two temperature sensors (4) of outer barrel of absorber wall (15) both sides are less than the water cooling temperature set
Value then switches off the pump (3).It is located at piston rod (7) as preferably described vibration frequency sensor (11) and shock absorber body is oriented to
The inside intersection of seat (10), it so more can accurately measure the vibration frequency of damper body (8);If it is distributed in outside shock absorber
The temperature averages of two temperature sensors (4) of barrel (15) both sides are less than the wind chill temperatures value of setting and are distributed in cooling water
The temperature value of two temperature sensor (4) average values again smaller than setting of (5) is managed, then closes electric fan (6).
Described cooling water pipe (5) and the threshold temperature of shock absorber body (8) setting are different, when temperature sensor (4)
Measured temperature is both less than air-cooled threshold values, and then electric fan (6) is closed;When temperature sensor (4) measured temperature be both greater than it is air-cooled
Threshold values, then electric fan unlatching and rotary head;It is less than cooling when temperature sensor (4) measured temperature is more than shock absorber body (8)
The temperature value of water pipe setting, then electric fan (6) unlatching but not rotary head;When temperature sensor (4), measured temperature is less than shock absorber
Body (8) and more than cooling water pipe setting temperature value, then electric fan (6) open and rotary head.
Described cooled plate (14) is distributed in the both sides of shock absorber body (8), and cold water plate (14) connects with cooling water pipe (5)
Connect;After water-cooling terminates, cooling water comes back to water tank (2) after the radiating of natural wind and electric fan (6);As
