Abstract
The utility model discloses a fan clutch of a heavy automobile. A driving disc is fixedly connected on an end face of the inner side of an intermediate ring sleeve of a three-ring bearing, a plurality of permanent magnets are distributed and connected on an inner end face of the driving disc and correspond to soft magnets connected on an end face of an inner cavity of a fan fixing disc, and elastic pieces are arranged on an outer end face of the driving disc and elastically connected with an inner actuation disc. Since connection and transmission between the driving disc and the fan fixing disc is realized by the three-ring bearing, a second bearing used in a driving disc in the prior art is omitted, so that compact structure, small size and low production cost of the fan clutch are realized. The three-ring bearing is arranged at the outer end of the fan fixing disc and is good in radiating condition during working, so that the bearing is guaranteed to work in normal temperature conditions, the service life of the fan clutch of the heavy automobile is effectively prolonged, and utilization cost of users is obviously reduced.
Description
(1) technical field: the utility model relates to fan clutch device; Be specifically related to a kind of heavy-duty car fan clutch.
(2) background technique: when the medium and heavy automobile electromagnetic fan clutch of prior art is worked, mainly be rotatedly connected by clutch shaft bearing and the transmission shaft of fan fixed disk by inside and outside two rings, and on described transmission shaft, establish second bearing in addition and be rotatably connected with drive plate, by the soft magnet on the described drive plate end face, the magnetic field suction that some block permanent magnets that the resonator end surface distribution is connected with in the relative fan fixed disk produce, the drive fan fixed tray drives fan blade and rotates, and realizes the radiating and cooling to motor car engine work water temperature.It exists not enough: the one, and described fan fixed disk is connected with transmission shaft by first, second bearing successively with drive plate, complex structure, volume increases, and has obviously increased production cost of products; The 2nd, second bearing that is rotatedly connected with described drive plate is positioned at the inside of automobile electromagnetic fan clutch, the ventilation and heat condition is relatively poor, electromagnetic core produces the heat of high temperature that eddy current magnetism forms during work, lubricant grease dilution in described second bearing is overflowed, cause " dry grinding " of rolling element and the inner and outer rings track of described bearing, the too early wearing and tearing that aggravated second bearing damage.When described bearing wear breaking-up needs repairing replacing, garage's daily life of a family is because removing and installing inconvenience, the automobile electromagnetic fan clutch of integral body done scrap processing and renew separately, reduced the operating life of automobile electromagnetic fan clutch thus, obviously increased user's user cost.
(3) summary of the invention: at the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of heavy-duty car fan clutch, is intended to realize reducing production costs, and improves operating life and minimizing user's user cost.
For achieving the above object, the technological scheme of a kind of heavy-duty car fan clutch of the utility model is to realize like this, mainly by fan fixed disk by interior, in, outer three collar bearings and transmission shaft one end be rotatedly connected, and the transmission shaft the other end and the belt pulley rotation composition that joins; It is that middle ring sleeve inner side end at described three collar bearings is fixed with drive plate, and the some block permanent magnets that distribute and be connected with on the drive plate interior edge face are corresponding with the soft magnet that resonator end surface in the fan fixed disk is connected with; Be connected with spring sheet in the exterior edge face of described drive plate and interior adhesive dish elasticity is joined.
When implementing technique scheme, it is corresponding that the end face of described some block permanent magnets and the interior resonator end surface of fan fixed disk are the gap, is fixed with soft magnet in the resonator end surface in described fan fixed disk.
The utility model is taked said structure, drive plate and fan fixed disk is shared three collar bearings be connected transmission, has reduced the second used bearing of drive plate in the prior art, has realized that product with compact structure, volume are little, have reduced cost of production; Three collar bearings are positioned at the outer end of fan fixed disk, and the ventilation and heat condition is good in the work, have guaranteed the normal working temperature of bearing, have prolonged the operating life of automobile fan clutch effectively, have obviously reduced user's user cost.
(4) description of drawings: Fig. 1 is a kind of embodiment's of the utility model sectional view;
Fig. 2 is the another kind of embodiment's of the utility model sectional view.
(5) embodiment: Fig. 1, shown in Figure 2.This heavy-duty car fan clutch, mainly by fan fixed disk by interior, in, outer three collar bearings and transmission shaft 2 one ends are rotatedly connected, and the transmission shaft the other end and the belt pulley rotation composition that joins; It is that middle ring sleeve 1 inner side end at described three collar bearings is fixed with drive plate 9, and the some block permanent magnets 5 that distribute and be connected with on the drive plate interior edge face are corresponding with the soft magnet 3 that resonator end surface in the fan fixed disk is connected with; On the exterior edge face of described drive plate 9 by being connected with spring sheet and interior adhesive dish 7 elasticity are joined.Usually to be the gap corresponding for the end face of described some block permanent magnets 5 and the interior resonator end surface of fan fixed disk, is fixed with soft magnet 3 (Fig. 1, shown in Figure 2) in described fan fixed disk in the resonator end surface.
During work, the utility model belt pulley link to each other with the motor car engine belt pulley (Fig. 1, shown in Figure 2).When the engine operation water temperature reaches set temperature value, electromagnetic core 8 gets in the temp controller control, the eddy current magnetism that forms is by adhesive dish 7 in drive plate 6 adhesives, under the spring sheet that interior adhesive dish end face elasticity connects drives, drive drive plate 9 together with middle ring sleeve 1 relative transmission shaft 2 rotation works of three collar bearings, the uniform some block permanent magnets 5 that are connected with on this moment drive plate 9 interior edge faces, the magnetic field suction that soft magnet 3 in the relative fan fixed disk in the resonator end surface produces, the fan blade 4 that is connected with on the drive fan fixed tray is done differential relative to the rotating speed of transmission shaft 2 and is rotated, and motor car engine work water temperature is carried out radiating and cooling (Fig. 1, shown in Figure 2).
The utility model is connected transmission by drive plate 9 and fan fixed disk are shared three collar bearings, has reduced the second used bearing of drive plate in the prior art, has realized that product with compact structure, volume are little, have reduced cost of production; Three collar bearings are positioned at the outer end of fan fixed disk, and the ventilation and heat condition is better in the work, guarantee that bearing works under normal temperature conditions, have prolonged the operating life of automobile fan clutch effectively, have obviously reduced user's user cost.
The above only is preferred implementation of the present utility model.Be noted that for those of ordinary skill in the art; with essentially identical means; realize essentially identical function; reach essentially identical effect; need not through creative work other technical characteristics with regard to obviously associating; can also replace modification and/or the improvement of making some kinds of basic identical modes, these variations should be considered as equivalent feature, all belong within the protection domain of the utility model patent.
