Background technique
Usually, large vehicle for example bus, truck or trailer is equipped with various Pneumatic actuator, comprises utilizing the pneumatic brake that compressed-air actuated pressure brakes and the pneumatic opening/closing of switch door automatically.Supply air compressor that the pressurized air of this Pneumatic actuator can move by the power by motor and offer gas holder and be stored in the gas holder, thereby pressurized air can be provided afterwards.For this reason, pressurized air should be stored in the gas holder and keep suitable pressure always.
Fig. 1 illustrates the example of the conventional air compressor of action by this way.This air compressor comprises: be installed in the bent axle 2 in the crankcase 1 that is attached on the motor; Driving gear 3, this gear 3 are connected to the front end of bent axle by axle and are meshed to receive power from motor with the timing gear (not shown) of motor; Piston (not shown), this piston pass through the bent axle to-and-fro motion in the cylinder that extends above crankcase, pressurized air is offered gas holder 5; And emptier 6, this emptier moves in response to the signal pressure of transmitting by regulator 7, thereby when the internal pressure of gas holder surpasses predetermined value, prevent from pressurized air is offered gas holder, and when the pressure of gas holder descends, allow to provide once more pressurized air.
This air compressor moves by this way, promptly transmits power that motors produce by driving gear 3 so that bent axle 2 rotations, with piston in the cylinder 4 of bent axle interlocking pressurized air is offered gas holder 5.When the internal pressure that makes this gas holder continuously to gas holder 5 supply pressurized air surpasses predetermined value, transmit signal pressure by regulator 7 to emptier 6, air compressor idle running thereby this emptier can move.Thereby, stop to provide pressurized air to gas holder 5.After this, if pressure descends, then emptier carries out negative actuation, thereby can provide pressurized air to gas holder again.
But, in conventional air compressor, even because the action of emptier 6 and not when gas holder 5 provides pressurized air, the still idle running continuously of this air compressor is so waste causes the huge waste of fuel by the power that motor produces continuously.Therefore, shortcoming is that this deviates from mutually with the mileage oil consumption that improves vehicle.
In addition, along with bent axle 2 rotation and the continuous to-and-fro motion of piston, the inside temperature of cylinder can be owing to frictional heat raises, and the consumption that offers the machine oil of crankcase simultaneously increases.Because the hot air of discharging comprises and the proportional a large amount of pollutants of the increase of oil consumption, therefore can cause atmospheric pollution and environmental pollution.In addition, the wear rate of increase can produce noise, and can shorten the life-span of air compressor greatly.

Embodiment
Describe air compressor according to a preferred embodiment of the invention below with reference to accompanying drawings in detail.
Fig. 3 is the perspective exploded view according to the air compressor of the embodiment of the invention, and Fig. 4 A and 4B are respectively the sectional views of bent axle that air compressor the is shown state that moves forward and move backward.
Crankcase 10 according to the air compressor of the embodiment of the invention is attached to motor 100.Bent axle 20 can be installed in the crank chamber 11 with rotating freely, and this crank chamber level runs through the bottom of crankcase and forms.
The front end of bent axle 20 passes lining 12 and exposes, this lining by snap ring be connected to crank chamber 11 front end in case anti-avulsion fall.Then, the front end that exposes with bent axle is placed in the motor 100.
In addition, the front end of bent axle 20 has the tapered stage casing of its excircle, and central siphon 21 is connected to this stage casing, and the inner circumference of this central siphon is tapered and matches with the stage casing with this crankshaft front end portion, and the excircle of this central siphon forms spline (keyway, teeth groove) 21a.This central siphon is fixing by nut 22, and this nut is fastened on the front end of bent axle.
Therefore, under the state that central siphon 21 is installed around the stage casing of the front end of bent axle 20, central siphon 21 is plugged between the front end and nut 22 of lining 12, thereby this central siphon can be connected to this bent axle to rotate integratedly with it.
Install around the excircle of lining 12 front ends with the driving gear 30 that power is passed to bent axle 20 from motor with the timing gear engagement of motor 100, these lining 12 front ends pass the front end of crank chamber 11 and expose.
Between the inner circumference of the excircle of central siphon 21 front ends and driving gear 30, clutch 40 is installed, giving bent axle 20 or cut off this power from the transmission of power that motor is delivered to driving gear.
The internal diameter of the axis hole of each driver plate 44 is all greater than the external diameter of central siphon 21, and the excircle of driver plate 44 forms spline 44a is arranged, to engage with spline 32 that inner circumference at driving gear 30 forms.The external diameter of each friction ring flat-plate 45 is all less than the external diameter of driver plate, and the inner circumference of the axis hole of friction ring flat-plate is formed with spline 45a, to engage with spline 21a that excircle at central siphon forms.
Therefore, the axis hole of driver plate 44 and central siphon 21 are spaced apart, and engage with the spline 32 that forms on driving gear 30 at the spline 44a that forms on the excircle of driver plate 44.The inner circumference of excircle and the driving gear of friction ring flat-plate 45 is spaced apart, and the spline 45a that forms at the inner circumference of axis hole engages with spline 21a in the excircle formation of central siphon.
In clutch 40, if movable ring flat-plate 43 is promoted backward by the repulsive force of ring flat-plate spring 42, then central siphon 21 is pushed rearward and moves apart from t, and this distance also is the distance that movable ring flat-plate is pushed.Therefore, bent axle 20 moves backward with central siphon.Correspondingly, driver plate 44 and friction ring flat-plate 45 also are pushed rearward moving.
At this moment, because the rear portion of driver plate 44 and friction ring flat-plate 45 is connected in the rear end step supporting of driving gear 30 inner circumferences on the lining 12, so the closely contact and connecting integratedly mutually between the rear end of this driving gear step and the movable ring flat-plate 43 that promoted backward by the repulsive force of ring flat-plate spring 42 of driver plate and friction ring flat-plate.
In this state, when the power of motor 100 passes to driving gear 30 by timing gear, thereby and make driving gear when rotation, rotating force passes to central siphon 21 from driving gear by driver plate 44 and the friction ring flat-plate 45 that one connects, thereby makes bent axle 20 rotations.
That is, the rotating force of driving gear 30 passes to driver plate 44 by the spline 44a that engages with spline 32.Then, the friction ring flat-plate 45 that is integrally connected to driver plate rotates with driver plate.After this rotating force is passed to central siphon 21 by the spline 21a that the spline 45a with the friction ring flat-plate engages.
Be used to make the compressed air cylinder 50 that has moved forward to be installed in the rear end of crank chamber 11 by the mobile backward bent axle 20 of the repulsive force of ring flat-plate spring 42.
Compressed air cylinder 50 comprises: lid 51, and this lid connects so that be sealed in the rear end of the opening of crank chamber, and is formed with inlet 511, introduces compressed-air actuated signal pressure by this inlet from regulator 61; And piston 52, this piston be installed in the internal cavities of this compressed air cylinder and with one with move forward and backward apart from the t proportional band-this is the distance that movable ring flat-plate 43 is promoted backward by the repulsive force of ring flat-plate spring 42 apart from t.The rear end of bent axle 20 is connected to the central part in the front of piston 52.
The rear end of piston 52 supporting crankshafts 20, thus this bent axle can rotate reposefully; Simultaneously, introduce compressed air cylinder 50 from regulator 60 by inlet 511 if the pressure of gas holder 60 compressed airs surpasses predetermined value and is used as signal pressure, then this piston forward moves so that bent axle moves forward.
In this state, because the central siphon of installing around the front end of the bent axle 20 that moved forward 21 promotion activity ring flat-plate 43 and make it mobile forward in the scope of distance t, so ring flat-plate spring 42 is compressed, simultaneously, the repulsive force driver plate 44 that closely contacts mutually and the ring flat-plate 45 urgent states of touching that connect airtight that rub because of this ring flat-plate spring unclamp, and keep sliding mode then.Thereby this bent axle was cut off by clutch 40 and being connected of driving gear 30.
When cutting off connection in this way, even driving gear 30 rotations, this rotating force can not pass to central siphon 21 yet, thereby bent axle 20 can not rotate.Therefore, driving gear only dallies.
In each pump chamber 13 that extends perpendicular to the crank chamber 11 of crankcase 10, pump piston 14 is installed all.When crankshaft rotating, pump piston is by connecting rod 15 to-and-fro motion, and an end of this connecting rod is connected to the horizontal component 20a of bent axle 20 and pressurized air is offered gas holder 60.
The other end of connecting rod 15 inserts and connects groove 141, this groove be formed on pump piston 14 central authorities in case opening towards crank chamber 11.Connect the front and back width f (see Fig. 7 A and 7B) of the Inner Dimension r of groove greater than this connecting rod.The middle part that axis hole 142 levels are crossed this pump piston.
Therefore, when wrist pin 16 runs through the shaft through-hole of the other end that is arranged on connecting rod 15 and be fixedly mounted in the axis hole 142, be connected to by wrist pin under the state of piston at connecting rod, this connecting rod horizontal slip is to move forward and backward in the scope of the front and back of this connecting rod width f and the difference in size of the internal diameter r that connects groove.
Construct this structural reason and be, because pump piston 14 only is mounted to to-and-fro motion in pump chamber 13, and bent axle 20 is mounted to and moves forward and backward, thus connecting rod 15 should move forward and backward with bent axle so that make pump piston to-and-fro motion in pump chamber.
The open top of pump chamber 13 is covered by top cover 17, and this top cover has exhaust port 171, can give gas holder 60 with the compressed air delivery that pump piston 14 produces by this exhaust port.
The air compressor according to the embodiment of the invention of structure is operated by motor 100 as mentioned above.When motor 100 moves under following state, power passes to bent axle by driving gear, clutch and the central siphon with the timing gear engagement, thereby make this crankshaft rotating, driver plate 44 and friction ring flat-plate 45 that the repulsive force that described state is a bent axle 20 by ring flat-plate spring 42 moves backward and is plugged between the rear end step of movable ring flat-plate 43 and driving gear 30 closely make contact to an integral body mutually, and promptly clutch 40 is connected to driving gear the state of central siphon 21.
In this state, pump piston 14 to-and-fro motion in pump chamber 13 by connecting rod 15.The pressurized air that produces in this process flows to gas holder 60 then by exhaust port 171 discharges and is stored in wherein.
If continuously pressurized air is provided and makes the compressed-air actuated pressure that flows to this gas holder surpass predetermined value to gas holder 60, signal pressure-be that pressurized air-quilt pass through to enter the mouth 511 from regulator 61 introducing compressed air cylinders 50 then.Because making, the signal pressure of introducing promotes the repulsive force of the power of piston 52, so bent axle 20 moves forward greater than ring flat-plate spring 42.
At this moment, because the bent axle 20 promotion activity ring flat-plates 43 that move forward, so ring flat-plate spring 42 is compressed.Therefore, the tight contact condition that has closely made contact to the driver plate 44 of an integral body and the ring flat-plate 45 that rubs by the repulsive force of ring flat-plate spring is released, thereby described plate can be separated from one another.As a result, driving gear 30 was cut off by clutch 40 and being connected of central siphon 21.
When this connection by clutch 40 was cut off, driving gear 30 was because of the rotating force rotation continuously from motor 100, but this rotating force is not delivered to central siphon 21.Therefore, driving gear idle running, and bent axle 20 does not rotate.
Therefore, because air compressor do not move, thus stop to provide pressurized air to gas holder 60, thus can prevent the unnecessary rising of pressure and avoid the loss of the power of motor 100.
After this, gas holder 60 interior pressurized air have been used and the internal pressure of this gas holder drops under the predetermined value if be stored in, and then the signal pressure of introducing compressed air cylinders 50 by regulator 61 is cut off, thereby reduces the pressure in the compressed air cylinder.Therefore, the repulsive force of ring flat-plate spring 42 is applied on movable ring flat-plate 43 and the bent axle 20, to promote and to move described movable ring flat-plate and bent axle backward.
Then, driver plate 44 closely contacts mutually with friction ring flat-plate 45, and driving gear 30 is connected to central siphon 21 by clutch 40, thereby can be with the transmission of power of motor 100 to bent axle 20, and air compressor moves once more thus.Pressurized air is offered gas holder 60 continuously, reaches predetermined value up to compressed-air actuated pressure.
In this process, as long as the distance that bent axle 20 and connecting rod 15 move forward and backward is enough to the tight contact condition of driver plate 44 and friction ring flat-plate 45 in the loosen the clutch 40, this distance can be very little.Therefore, even connecting rod is positioned at the position of the central axis that departs from pump piston 14, because throw of eccentric is less, so pump piston still can carry out normal to-and-fro motion in pump chamber 13 always.
Simultaneously, move forward and backward and make pump piston 14 to-and-fro motion although illustrated by the example relevant with connecting rod 15 that embodiments of the invention-this connecting rod 15 is mounted to bent axle 20, the present invention is not limited thereto.Can connecting rod be configured to move forward and backward, and only bent axle be configured to move forward and backward.
For this reason, with the length of the horizontal component 20a of the joining bent axle 20 in the end of the connecting rod 15 front and back width f greater than this connecting rod, thereby this horizontal component slidably.On the contrary, the upper end of connecting rod be connected to pump piston 14 in case only the rotation and do not move forward and backward.
Although also have many modification except present embodiment, clearly, the modification that any rotating force that wherein will be mounted to the bent axle 20 that moves forward and backward passes to reciprocating pump piston 14 all falls within the scope of the invention.
In addition, single pump chamber 13 can be set to be applicable to the less compressed-air actuated vehicle of use and to reduce cost.Clearly, this situation also falls within the scope of the invention.
But, under the situation of using a lot of compressed-air actuated large vehicles, need provide a plurality of pump chambers 13 so that pressurized air is provided fast.
In the air compressor that as above moves according to an embodiment of the invention, if being reduced to, the internal pressure of gas holder is lower than predetermined value, then air compressor moves so that pressurized air is offered gas holder by the power that receives motor.If the internal pressure of gas holder surpasses predetermined value, then only make driving gear idle running with the transmission of cut-out, thereby stop the action of air compressor from the power of motor.Therefore, the advantage of this air compressor is to prevent the power loss of motor, thereby and reduce the consumption of fuel and fuel oil greatly, thereby improve the mileage oil consumption of vehicle greatly.
In addition, because only action when needed of air compressor, so can reduce the wear rate of this air compressor, and prevent to shorten the life-span of air compressor.Reduce the frictional heat in the air compressor, thereby reduced the temperature of discharged air.Because air compressor discharged air not when being failure to actuate is so (the present invention) has the advantage that can reduce atmospheric pollution and environmental pollution.
