Description
Technical field
The utility model relates to automobile engine accessory, is specifically related to a kind of cooling fan of engine clutch.
Background technique
Engine-cooling system ensure that motor maintains in suitable temperature range under all operating modes, the constituent of motor car engine is pump circulation constituent, it comprises water jacket and other additional devices etc. in water pump, radiator, cooling fan, thermostat, compensation bucket, engine body and cylinder head, in order to reduce fan power consumption, reduce noise and wearing and tearing, prevent motor excessively cold, reduce and pollute, fuel saving, the operation of temperature to cooling fan according to circulating water controls.
Chinese patent literature CN1097040A discloses a kind of electric fan clutch driven by memory spring January 4 nineteen ninety-five, it is by initiative taper dish, from mantle dish, shape memory alloy spring and rolling bearing are formed, shape memory alloy spring is located at transmission shaft external part on the right side of initiative taper dish central authorities, reset helical spring is established on the left of shape memory alloy spring, the other end of shape memory alloy spring is spacing by the spring seat be contained on transmission shaft end surface, Returnning spring is placed on spring seat, and spring seat is fixed on axle head by screw and packing ring.Utilize the temperature-sensitive characteristic induction generator radiator temperature of shape memory alloy spring and self adaption drives friction disk to combine, achieve automatic clutch and the intelligent speed-regulating of fan clutch.But due to initiative taper dish with transmits moment of rotation from mantle dish by cone dish rubbing surface, in order to two taper-face contact are reliable, require to manufacture machining accuracy higher, simultaneously initiative taper dish and from mantle dish without encapsulation, easily pile up dust and cause controlling inefficacy.
Model utility content
For prior art Problems existing, technical problem to be solved in the utility model is just to provide a kind of cooling fan of engine clutch, and its manufacturing is easy, and can not accumulate dust.
Technical problem to be solved in the utility model is realized by such technological scheme, it comprises front case and rear case, front case is connected conjunction by attachment screw with rear case and closes integral, close in the inner chamber closed at front case and rear case and driving disc and driven disc are housed, driving disc is fixedly connected with transmission shaft by set screw, transmission shaft by bearing assemble on rear case; Driven disc is fixedly connected with driven shaft, driven shaft is arranged on the axle sleeve of front case, guide pillar through front case and with front case Spielpassung, shape memory alloy spring is sleeved on guide pillar segmentum laterale, Returnning spring is sleeved on guide pillar medial segment, pretension swivel nut is threaded on front case along guide pillar direction, shape memory alloy spring one end contacts with pretension swivel nut inner bottom surface, the other end contacts with ring plate outer side surface in the middle part of guide pillar, Returnning spring one end contacts with ring plate inner side surface in the middle part of guide pillar, the other end contacts with front case outer side surface, and pretension swivel nut leaves vent.
Driving disc and driven disc are contained in front case to the utility model and rear case closes in the inner chamber closed, and can keep driving disc and driven disc totally, not be stained with collection dust, and reliable, simultaneously by rubbing surface transferring power between driving disc and driven disc, manufacturing is easy.
So the utility model has following advantage: manufacturing is easy, and can not accumulate dust, reliable.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is structural representation of the present utility model;
In figure: 1. shape memory alloy spring; 2. Returnning spring; 3. pretension swivel nut; 4. set screw; 5. driven disc; 6. guide pillar; 7. vent; 8. front case; 9. attachment screw; 10. driving disc; 11. rear cases; 12. bearings; 13. transmission shafts; 14. driven shafts; 15. lubricating grease storing cavitys; 16. axle sleeves.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, the utility model comprises front case 8 and rear case 11, front case 8 is connected conjunction by attachment screw 9 with rear case 11 and closes integral, close in the inner chamber closed at front case 8 and rear case 11 and driving disc 10 and driven disc 5 are housed, driving disc 10 is fixedly connected with transmission shaft 13 by set screw 4, and transmission shaft 13 is assemblied on rear case 11 by bearing 12, driven disc 5 is fixedly connected with driven shaft 14, driven shaft 14 is arranged on the axle sleeve 16 of front case 8, guide pillar 6 through front case 8 and with front case 8 Spielpassung, shape memory alloy spring 1 is sleeved on guide pillar 6 segmentum laterale, Returnning spring 2 is sleeved on guide pillar 6 medial segment, pretension swivel nut 3 is threaded on front case 8 along guide pillar 6 direction, shape memory alloy spring 1 one end contacts with pretension swivel nut 3 inner bottom surface, the other end contacts with ring plate outer side surface in the middle part of guide pillar 6, Returnning spring 2 one end contacts with ring plate inner side surface in the middle part of guide pillar 6, the other end contacts with front case 8 outer side surface, pretension swivel nut 3 leaves vent 7.
Be provided with lubricating grease storing cavity 15 in the middle part of axle sleeve 16, the lubricating grease in lubricating grease storing cavity 15 provides lubrication for moving axially of driven shaft 14.
Transmission shaft 13 is connected with engine crankshaft.
Working principle of the present utility model is: when by vent 7, shape memory alloy spring 1 senses that the temperature of radiator moves axially higher than producing during a certain temperature, and promote guide pillar 6 and internally put in, guide pillar 6 promotes driven disc 5 and contacts with driving disc 10 and produce friction torque and drive driven shaft 14 to rotate; The axial driving force of the higher shape memory alloy spring of temperature 1 is larger, and driven shaft 14 rotates faster until and transmission shaft run-in synchronism.When the temperature of radiator reduces, shape memory alloy spring 1 shrinks and driven disc 5 is separated with driving disc 10 and not transmitting torque under the effect of return spring 2.
