In order to be fixed in an axial position in housing 206 inside by bearing components 230, employ a wavy spring component 280 and bearing cage component 282.Bearing cage component 282 is threadedly attached on housing 206, as shown in by reference to numbers 284.
Stop dog component 270 is used to carry out the axial motion of this friction plate component 234 of backstop when solenoid component 250 obtains electric, as being described following.Returnning spring 290 to be positioned between nut member 260 and friction plate component 234 and to work when solenoid component 250 activated and makes friction plate component 234 return the de-engagement positio of its machinery.
Solenoid 252 is powered by a circuit board (not shown).Electrical lead wire and wire can be inserted mode system in housing 206, electrical signal is transported to solenoid component 252.This circuit board is connected with the electronic control unit (ECU) of this vehicle further by the vehicle communication network as CAN network.Water pump component controller circuit board can also be positioned in housing 206, may have donut shape.
The actuating of water pump is that the cooling required for motor is selected.Related data is fed to ECU by multiple sensor, and then ECU sends a request signal to pump controller and activates this pump.Then this pump controller engages this friction clutch, allows impeller to be driven by belt pulley like this.
When water pump does not need to activate, solenoid component 250 makes friction clutch pack remain on de-engagement positio.This is shown in Figure 9.When solenoid component 252 is produced a flux return 300 during electric actuation, this flux return works to overcome the power of these coiled spring member 302 thus this armature plate 232 is pulled to solenoid component.When armature plate 232 is pulled to solenoid, Returnning spring 290 makes friction plate 234 fixing be resisted against on stop dog component 270.In this case, the friction material on friction plate 234 does not contact with lid component 208 or armature plate 232.
The quantity of helical spring 302 and their bias force determine according to power required in assembly.Shown in the drawings of six helical springs 302, but the number more or more less than this can be there is according to required power.
Enable in pattern in the releasing of this operation, the outside of these friction materials of friction plate exists air gap, and input end (pulley member) and output terminal (shaft component) disconnect.Which eliminate any interaction, such as, bearing resistance between input end and output terminal.
In order to produce suitable flux return 300, pulley member 10 ' has the multiple openings producing air gap.This illustrates particularly in fig. 7, also shown in Figure 9.The opening of perforate 22 ' and the 32 ' formation of the alignment in corresponding cup-shaped member 20 ' and 30 ' defines in fact an annular opening circle.By these air gaps, this pulley member is in fact an outer annular circle and an inner annular circle separated for electromagnetism object.The size of opening or the line of rabbet joint, shape and quantity are not conclusive, as long as they meet the object producing an open circuit in magnetic flux.
This flux return 300 has been shown in Fig. 9.This flux return extends past solenoid shell 206, the driving belt anastomosis part 223 of pulley member 10 ', the outer annular circle part of pulley member, and then jump to armature plate component 232, and next get back to the inner annular circle part of pulley member 10 ', turn back to solenoid shell at this.This armature member tightly draws and leans against in this pulley member by this loop.In this case, water pump vane 204 does not activated.
Fig. 8 depicts the situation that solenoid component 250 does not activated.Situation that Here it is " Fail safe ".Water pump is made to be driven by dynamo belt and activated like this.In this case, helical spring 302 to exert a force to armature member 232 away from the direction of solenoid component away from pulley member.This makes armature member 232 contact this friction member 236, this friction member and then force friction member 238 to contact the internal surface 209 of lid component 208.Because armature member, pulley member and lid component are all fixed together, this shaft component 214 is made to rotate with identical speed with impeller component 204 like this.
Arrow 320 in Fig. 8 shows a moment of torsion transfer path that shaft component is mechanically rotated.In the clutch that this engages, friction plate component 234 is sandwiched between lid component 208 and armature member 232 and moment of torsion is conveyed through the both sides of friction plate.Also there is one from pulley member 10 ', through fastening piece 210, armature plate component 232, friction plate component 234, nut member 290 and arrive the moment of torsion transfer path of axle 214.
Figure 10 schematically depict the purposes of friction clutch of the present invention for an operation cooling fan.This cooling fan attachment mechanism total by reference numeral 400 represents.
Friction clutch mechanism 410 is substantially identical with the friction clutch mechanism for making water pump vane optionally rotate described above.In this embodiment, friction clutch mechanism is used for cooling fan is rotated.These same parts are by representing with the same reference numbers set forth in the other drawings.The main distinction is, shaft component 214 ' can make a cooling fan assembly 420 rotate when activateding.Fan component 420 comprises cooling fan 430 and a central hub member 450 of an a large amount of vane member 440 of band.Hub member 450 is attached on shaft component 214 ' fastenedly, and fan 430 is attached on hub member 450 fastenedly, thus to make when shaft component rotates fan and blade by rotation and rotate with identical speed.Any conventional equipment or mechanism can be used to be attached together by these parts thus to make them rotate together.
In addition, pulley member 10 is " with identical with the pulley member 10 ' described by Fig. 9 about Fig. 6, Fig. 7, Fig. 7 A, Fig. 8 above.
Current water pump and cooling fan arrangement are designed to be that spring engages, and thus under control failure conditions (as losing electric power), this fitting device is dynamic.Doing so provides the function of " fail safe ", this function means that this device is given tacit consent to when dead electricity and enters its " work " state.If the electrical system of coolant pump lost efficacy, solenoid was understood dead electricity thus was made helical spring force friction clutch pack to become joint.Therefore pump will run with mechanical mode and impeller is driven by clutch pack by pulley member, thus prevent overheated.
