Abstract
The utility model discloses a kind of Pneumatic friction type fan clutch, friction ring is arranged between driven disc and drive plate, extension type seal air cavity mechanism comprises cylinder, piston and ventilating shaft, cylinder is arranged on the outer end of driven disc, elastic body is arranged on the axial periphery of ventilating shaft, and contact Permanent Magnetic Gear transmission mechanism comprises fixed plate, aluminium dish, permanent magnet and magnetic guiding loop, and fixed plate and aluminium dish are arranged on drive plate, magnetic guiding loop is arranged on driven disc, and permanent magnet is arranged on aluminium dish.The utility model, when connecting suitable pressurized gas, produces pressure and forces between drive plate and driven disc and depart between cylinder and piston, drive plate drives driven disc to slowly run by contact Permanent Magnetic Gear transmission mechanism; When stopping air feed; the elastic force producing by Compress Spring between drive plate and driven disc makes both and friction ring produce frictional force, thereby drives driven disc to rotate by the speed consistent with drive plate, failure rate is low; for ease of maintenaince, and there is feature reliable, to engine failure protection.
Description
Technical field
the utility model relates to a kind of clutch, is specifically related to a kind of Pneumatic friction type fan clutch for engine cooling.
Background technique
automobile needs the time of fan work to be about 1/3 in the process of moving, and cooling fan is 5% ~ 8% of consumption of engine rated power, can reduce oil consumption 4% ~ 5% after using fan clutch, so increasing commercial car provided with fan clutch all on market.Traditional fan clutch adopts silicone oil as working medium, utilizes the viscous force of silicone oil to realize transmission, controls the engagement of fan clutch with separated, but transmission weak effect, and motor easily damages.
Summary of the invention
the utility model object is: a kind of Pneumatic friction type fan clutch is provided, adopts modular organization, and simple in structure, low cost of manufacture, transmission is effective.
the technical solution of the utility model is: a kind of Pneumatic friction type fan clutch, comprises driven disc, friction ring, drive plate, extension type seal air cavity mechanism, elastic body and contact Permanent Magnetic Gear transmission mechanism; Described friction ring is arranged between described driven disc and described drive plate, described extension type seal air cavity mechanism comprises cylinder, is arranged on piston and ventilating shaft in described cylinder chamber, described cylinder is arranged on the outer end of described driven disc, described elastic body is arranged on the axial periphery of described ventilating shaft, described contact Permanent Magnetic Gear transmission mechanism comprises fixed plate, aluminium dish, permanent magnet and magnetic guiding loop, described fixed plate and described aluminium dish are arranged on described drive plate, described magnetic guiding loop is arranged on described driven disc, and described permanent magnet is arranged on described aluminium dish.
further, described elastic body comprises spring support and Compress Spring, between described driven disc and described piston, deep groove ball bearing is installed, and between described drive plate and described ventilating shaft, deep groove ball bearing is also installed.
further, described friction ring is taper, thereby more flexible engagement is provided.
further, described drive plate is connected with described driven disc by pressing plate with needle bearing.
the utility model has the advantages that:
the utility model, when connecting suitable pressurized gas, produces pressure and forces between drive plate and driven disc and depart between cylinder and piston, drive plate drives driven disc to slowly run by contact Permanent Magnetic Gear transmission mechanism; When stopping air feed, the elastic force producing by Compress Spring between drive plate and driven disc makes both and friction ring produce frictional force, thereby drives driven disc to rotate by the speed consistent with drive plate; failure rate is low; reliable performance, for ease of maintenaince, and has feature reliable, to engine failure protection.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the utility model is further described:
fig. 1 is structural representation of the present utility model;
wherein: 1, driven disc, 2, friction ring, 3, pressing plate, 4, drive plate, 5, fixed plate, 6, aluminium dish, 7, Compress Spring, 8, spring support, 9, ventilating shaft, 10, permanent magnet, 11, magnetic guiding loop, 12, cylinder, 13, piston.
Embodiment
embodiment: shown in Figure 1, a kind of Pneumatic friction type fan clutch, comprises driven disc 1, friction ring 2, drive plate 4, extension type seal air cavity mechanism, elastic body and contact Permanent Magnetic Gear transmission mechanism, described friction ring 2 is arranged between described driven disc 1 and described drive plate 4, described extension type seal air cavity mechanism comprises cylinder 12, be arranged on piston 13 and ventilating shaft 9 in described cylinder 12 chambeies, described cylinder 12 is arranged on the outer end of described driven disc 1, described elastic body is arranged on the axial periphery of described ventilating shaft 9, described contact Permanent Magnetic Gear transmission mechanism comprises fixed plate 5, aluminium dish 6, permanent magnet 10 and magnetic guiding loop 11, described fixed plate 5 and described aluminium dish 6 are arranged on described drive plate 4, described magnetic guiding loop 11 is arranged on described driven disc 1, described permanent magnet 10 is arranged on described aluminium dish 6.
further, described elastic body comprises spring support 8 and Compress Spring 7, between described driven disc 1 and described piston 13, deep groove ball bearing is installed, and between described drive plate 4 and described ventilating shaft 9, deep groove ball bearing is also installed.
further, described friction ring 7 is taper.
further, described drive plate 4 use needle bearings are connected with described driven disc 1 by pressing plate 3.
working principle of the present utility model is:
pressurized air enters the air chamber between described cylinder 12 and described piston 13 by described ventilating shaft 9 inner vent holes, produce thrust, promote the movement of turning right of the described Compress Spring 7 of described driven disc 1 compressing, described driven disc 1, described friction ring 2 and described drive plate 4 are departed from, and described drive plate 4 now can drive described driven disc 1 to slowly run by described contact Permanent Magnetic Gear transmission mechanism;
while stopping air feed, pressurized air in the middle of air chamber can be discharged in the middle of atmosphere simultaneously, the elastic force that described Compress Spring 7 produces can make described driven disc 1 get back to original position, described like this driven disc 1, described friction ring 2 and described drive plate 4 can be by elastic compressions, obtain friction torque, thereby make described drive plate 4 and 1 combination of described driven disc, described driven disc 1 can be to rotate with the same speed of described drive plate 4.
certainly above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All modifications of doing according to the Spirit Essence of the utility model main technical schemes, within all should being encompassed in protection domain of the present utility model.
