In a preferred embodiment, two first O-ring seals 9 are arranged in two annular seal grooves arranged at intervals on the inner wall of the cantilever cylinder of the driven disc 16.
In a preferred embodiment, the second O-ring 15 is disposed in an annular seal groove formed in the spline shaft 4.
As a preferred embodiment, the sealing element is a profiled sealing ring 13; one end of the spline shaft 4 close to the driven disc 16 is provided with an annular dovetail groove, and the special-shaped sealing ring 13 is embedded into the annular dovetail groove; the cross section of the special-shaped sealing ring 13 is isosceles trapezoid.
In a preferred embodiment, more than three fan connecting studs 11 uniformly distributed along the circumferential direction are fixedly arranged on the end surface of the driven disc 16 far away from the spline shaft 4.
As a preferred embodiment, the outer edge of the driving disk 1 is connected with the engine pulley through more than three screws 5 which are uniformly distributed along the circumferential direction. The rotating speed of the belt pulley of the engine is the rotating speed of the driving disc.
As a preferred embodiment, the material of the friction disc 7 is aluminium.
The working principle of the pneumatic fan clutch is as follows:
as shown in fig. 1, when the air inlet of the spline shaft 4 is not ventilated, the friction disc 7 presses the friction strip 6 against the friction driving ring of the driving disc under the action of the wave spring 10; the driving plate 1 is driven by external force (preferably, the external force drives the driving plate 1 through an engine belt pulley), and the driven plate 16 rigidly connected with the friction plate 7 is driven to rotate through the friction strip 6 and the friction plate 7, so that a fan fixed on the driven plate 16 (preferably, fixed through the fan connecting stud 11) rotates, and the engaging function of the pneumatic fan clutch is realized; the friction bar 6 of the pneumatic fan clutch is able to transmit a sufficient rotational torque.
As shown in fig. 2, when the air inlet hole of the spline shaft 4 is ventilated, the compressed air reaches the vent hole of the driven disc 16 through the air inlet hole a and the air hole channel b of the spline shaft and then reaches the air cavity c between the piston seat 12 and the driven disc 16 through the spline housing installation hole of the driven disc 16; at this time, the air chamber c generates an outward thrust force against the driven disk 16 by the air pressure. When the thrust of the air pressure to the driven disc 16 is larger than the pretightening force of the wave spring 10, the wave spring 10 is compressed, the friction disc moves towards the driven disc 16, and the friction strip 6 is separated from the driving disc 1; at this time, the driving disk 1 rotates, the driven disk 16 does not rotate along with the driving disk 1, the fan stops rotating, and the pneumatic fan clutch has the separation function, so that the load of power such as an engine is reduced, and fuel is saved.
When the friction bars are worn to the design limit, the friction disc 7 and the driven disc 16 are pushed towards the driving disc 1 under the action of the wave spring 10, at the moment, the bottom surfaces of the vent holes of the driven disc 16 are contacted with the sealing piece on the spline shaft 4, and the air cavity c between the piston seat 12 and the driven disc 16 is reduced compared with the situation that the friction bars are not worn; therefore, when the air inlet hole of the spline shaft 4 is ventilated, compressed air reaches the air vent of the driven disc 16 through the air inlet hole a and the air vent channel b of the spline shaft, at the moment, the special-shaped sealing ring 13 is contacted with the bottom surface of the air vent of the driven disc 16 to form a sealing structure, the compressed air cannot reach the air cavity c between the piston seat 12 and the driven disc 16, the thrust of the compressed air to the driven disc 16 is far smaller than the pre-tightening force of the wave spring 10, the friction disc 7 enables the friction strip 6 to press the friction driving ring of the driving disc under the acting force of the wave spring 10, and the fan on the driven disc 16 continues to rotate. Under the working condition that the friction strips are abraded to the design limit, unless compressed air with high pressure is introduced into the air inlet holes of the spline shaft 4, the action area of the compressed air on the driven disc 16 is greatly reduced, and the pneumatic fan clutch cannot be separated, so that a large amount of heat generated by friction between metal pieces (the friction disc 7 and the driven disc 16) due to abrasion of the friction strips is avoided, parts such as an engine are damaged, and meanwhile, the driving disc 1 and the driven disc 16 are prevented from slipping, so that the rotating speed of a fan is reduced, and the cooling efficiency of the fan on a water tank is reduced; when the friction strip is worn to the designed limit and then is worn continuously, the driving disc 1 and the driven disc 16 slip, the water temperature sensor detects that the water temperature exceeds a preset value and then transmits a signal to the central console, and the central console gives an alarm through the instrument desk to inform a driver that the friction strip needs to be replaced.
