Description
Technical field:
The utility model relates to a kind of electromagnetic Clutch step by-step variable gear that is used for automobile air conditioning system control, belongs to the car air-conditioner technical field.
Background technique:
At present, automobile air conditioner compressor only uses a magnetic clutch, magnetic clutch is contained on the compressor, and its effect is: motor is by the belt drives magnetic clutch, when starting air-conditioning refrigeration system, switch on to magnetic clutch, magnetic clutch drives the compressor rotation work, after the magnetic clutch outage, and magnetic clutch idle running, compressor stops operating, and air conditioner stops refrigeration work.
Motor is to carry out transmission with fixing velocity ratio by clutch to the driving of compressor, the refrigeration performance of automotive air conditioning device and the rotation speed relation of air condition compressor are close, the speed per hour of automobile 60km/h of generally being based on its refrigeration performance designs, the speed range broad of motor car engine, automobile is when idling or lower-speed state, engine speed is low, the rotating speed of air condition compressor is also low, can cause the refrigerating capacity deficiency of air-conditioning system, and during galloping, the rotating speed of motor and compressor is also high, air conditioner refrigerating ability surplus, and the energy consumption of compressor is also high.For the urban bus that is driven the not merely vertical vehicle air conditioner of magnetic clutch by motor car engine is installed, the existing overwhelming majority is this situation, because the city bus automobile often is in low speed driving or idling mode, thereby the refrigerating capacity wretched insufficiency, cause the air conditioner refrigerating effect of urban bus generally relatively poor.
The common method that solves this class problem is to adopt free-standing car air-conditioner unit, promptly drive air condition compressor specially with a motor in addition separately, making compression, function is constant works on one or two moderate rotating speed, its refrigeration is not subjected to the influence of automobile master motor, but owing to increased a motor, will cause a series of challenges in the vehicle structure design, manufacture cost improves, and has also increased noise and engine exhaust emission simultaneously.
Summary of the invention:
The purpose of this utility model is exactly a kind of refrigeration deficiency can solve auto idle speed or low speed time of invention, and reduces the electromagnetic Clutch step by-step variable gear of air conditioning energy consumption when running at high speed.
For realizing above purpose, the technical solution of the utility model provides a kind of electromagnetic Clutch step by-step variable gear, its characteristics are, magnetic clutch in the middle of setting up one, driving wheel belt and follower belt, the driving wheel of middle magnetic clutch is connected with motor car engine by belt on one side, another side is connected with the driving wheel of electromagnetic clutch for compressor by the driving wheel belt, the follower of middle magnetic clutch is connected with the follower of electromagnetic clutch for compressor by the follower belt, automatic controller is connected with electromagnetic clutch for compressor with middle magnetic clutch respectively, electromagnetic clutch for compressor by key joint on compressor.
The utility model is by the difference adhesive of two magnetic clutchs, cooperate different belt wheel proportionings, with different velocity ratios with the power transmission of motor car engine to air condition compressor, and control according to engine speed, when the engine idle or the slow-speed of revolution, adopt high transmission ratio to improve the rotating speed of compressor, and then the heat pump performance when improving idling or low speed; When the high rotating speed of motor, adopt underneath drive recently to reduce the rotating speed of compressor, reduce air conditioning energy consumption.
The utility model has the advantages that the air conditioner refrigerating deficiency when having solved auto idle speed or low speed, and can reduce air conditioning energy consumption when running at high speed.
Description of drawings:
Fig. 1 is an electromagnetic Clutch step by-step variable gear structural drawing;
Fig. 2 is an electromagnetic Clutch step by-step variable gear drawing in side sectional elevation.
Embodiment:
As Fig. 1, shown in Figure 2, the electromagnetic Clutch step by-step variable gear is by middle magnetic clutch 1, electromagnetic clutch for compressor 2, driving wheel belt 3, follower belt 4, automatic controller 5 is formed, the driving wheel 6 of middle magnetic clutch 1 is connected with 1 of automobile engine 0 by belt 11 on one side, another side is connected with the driving wheel 8 of electromagnetic clutch for compressor 2 by driving wheel belt 3, the follower 7 of middle magnetic clutch 1 is connected with the follower 9 of electromagnetic clutch for compressor 2 by follower belt 4, automatic controller 5 is connected with electromagnetic clutch for compressor 2 with middle magnetic clutch 1 respectively, electromagnetic clutch for compressor 2 by key joint on compressor 12.
The driving wheel 6 of middle magnetic clutch 1, the diameter of follower 7 calculate according to required velocity ratio.The velocity ratio formula is:
Idling and low speed ratio: i=d
Send out/ d
6* d
8/ d
6
High-speed transmission ratio: i=d
Send out/ d
6* d
7/ d
9
The driving wheel 8 of electromagnetic clutch for compressor 2, the diameter of follower 9 calculate according to required velocity ratio.
When auto idle speed or low speed driving, the 2 energising adhesive work of automatic controller 5 control electromagnetic clutch for compressor, middle magnetic clutch 1 outage, then power passes to the driving wheel 6 of middle magnetic clutch 1 from the drive belt 11 of motor with bigger velocity ratio, pass to the driving wheel 8 of electromagnetic clutch for compressor 2 again by active belt 3, electromagnetic clutch for compressor 2 work backs drive follower 9, thereby drive compressor, and improve compressor rotary speed to improve refrigeration.
When galloping, magnetic clutch 1 energising adhesive work in the middle of automatic controller 5 controls, electromagnetic clutch for compressor 2 outages, the driving wheel 6 of magnetic clutch 1 in the middle of then power passes to from engine-driving belt 11 with less velocity ratio, middle magnetic clutch 1 work back drives follower 7, drive the follower 9 of electromagnetic clutch for compressor 2 by driven belt 4, thereby drive compressor, and reduce the energy consumption of the rotating speed of compressor with the control compressor.
