Embodiment's explanation

The side view of analysing and observe with part in Fig. 1 shows the throttling arrangement that is used for car combustion engine, and it is to be used for by accelerator pedal 10 (Fig. 5) Control of Automobile travelling speed and adjusting idling of IC engine rotating speed.Throttling arrangement has a throttling housing 11 and a governor body that is connected with flange in the side 12, and electronic idle running regulator 13 (Fig. 5) is contained in the governor body.In throttling housing 11, a duct segments 14 is arranged, this duct segments is received on the suction pipe of internal-combustion engine.The clean transverse section of duct segments 14 is by closure 15 controls, and the closure rotation is fixedly mounted on the throttle plate pin 16.Throttle plate pin 16 radially passes duct segments 14, and rotatably is positioned in two swivel bearings 17,18, and these two Bearing Installation are in two bearing supports (bearing adapter) 19,20 that constitute in throttling housing 11.Two axle heads 161 of throttle plate pin 16,162 endways side stretch out two bearing supports 19,20, at an axle head 161 actuator 21 is arranged, this actuator passes through a male part such as a rope drive device (Fig. 5) or a coupling bar are connected with accelerator pedal 10.Among the embodiment of actuator 21 shown in Figure 1, it has made rope sheave 23, and this rope sheave rotatably is seated on the axle head 161 of throttle plate pin, and overlaps 24 overlap joints with the servo-actuated that a rotation is fixed on the throttle plate pin 16.In the parts of rope sheave 23 and servo-actuated cover 24 overlap joints, an inside groove 25 towards throttle plate pin 16 (Fig. 1,5) is arranged, this inside groove along the circumferential direction extends in a rotation angle range, and in end side by each radially convex shoulder 251,252 (Fig. 5) restriction.The length of inside groove 25 in circumferencial direction is equivalent to rotation angle range, and like this, 23 generations rotatablely move to rope sheave, just can be by electronic idle running regulator 13 swivel air valve shafts 16.Constituted a radially-protruding block 241 on servo-actuated cover 24, it stretches in the inside groove 25, when operation rope sheave 23, has guaranteed the servo-actuated of throttle plate pin 16.Under the effect of Returnning spring 26, radially drawing servo-actuated cover 24 in convex shoulder 251 directions.Radially convex shoulder 252 is safety catch, such as it works when Returnning spring is malfunctioning, and inside groove 25 allows idle running regulator 13 operation throttle plate pins 16, and noting be used in this moment must operation rope sheave 23.Under Returnning spring 27 effect, rope sheave 23 is close to the block 28 on the throttling housing 11, the adjustment torque ratio Returnning spring 26 of Returnning spring 27 much bigger.When the motor 33 wrong controls that are arranged in idle running regulator 13, two blocks 64,65 (Fig. 5) that are arranged in governor body 12 are used for doing safety catch (Fig. 4,5).When normal operation, block 64,65 and radially convex shoulder 252 is inoperative.

In the embodiment in figure 1, two Returnning springs 26 and 27 have been made the torsion spring 29 and 30 of per two parallel actions, and they cross the axle head of throttle plate pin 16 mutually with one heart.Here, Returnning spring 26 and intort spring 29 as servo-actuated cover 24 with less reset torque, it is 24 hinged that one end and servo-actuated are overlapped, the other end and rope sheave 23 are hinged, and as the Returnning spring 27 of rope sheave 23 with have the outer torsion spring 30 of big reset torque, one end is on rope sheave 23, and the other end is on throttling housing 11.When inoperation accelerator pedal 10, actuator 21 is close to the block 28 of throttling housing 11, like this, has only electronic idle running regulator 13 to decide idling of IC engine to regulate the clean transverse section of the duct segments 14 of usefulness.If by operation accelerator pedal 10, by rope drive device rotation rope sheave 23, then the radially convex shoulder 251 of inside groove 25 makes block 241 servo-actuateds, and overlap 24 swivel air valve shafts 16 by rotating the servo-actuated that fixedly is seated on the throttle plate pin 16, by this, closure 15 discharges the clean transverse section of duct segments 14 more and more biglyyer.Like this, the radially convex shoulder 251 in rope sheave 23 on the inside groove 25 has constituted first rotary block 31, when operation accelerator pedal 10, in order to swing closure 15, can make throttle plate pin 16 along with rotating by this block.

Throttle plate pin 16 leaves the axle head of actuator 21, stretches into 12 li of governor bodies, there with electronic idle running regulator 13 couplings.Idle running regulator 13 has motor 33 (Fig. 4,5), and motor comes transmission regulator shaft 35 (Fig. 1,2) by the worm gearing 34 of a white row braking.Here, the worm screw 36 of worm gearing 34 (Fig. 4,5) rotation is fixed on the driven shaft of motor 33, and the worm gear 37 (Fig. 2) that meshes with worm screw 36 (Fig. 4,5) is seated on the regulator shaft 35 with rotatablely moving.Regulator shaft 35 swivel bearings are 12 li of governor bodies, and configuration like this, and promptly when governor body 12 was connected with throttling housing 11 flanges, regulator shaft and throttle plate pin 16 were in alignment.Be installed in the clutch 38 between regulator shaft 35 and the throttle plate pin 16, rotation is fixedly connected between regulator shaft 35 and throttle plate pin 16, and clutch 38 comprises that a rotation fixedly is seated in clutch device 381 on the regulator shaft and one and rotates the clutch device 382 that fixedly is seated on throttle plate pin 16 second axle heads 162.Here, clutch is to constitute like this, and when governor body 12 was connected with throttling housing 11 flanges, two clutch devices 381 and 382 were meshing with each other, and clutch 38 engages when mounted automatically.When motor 33 startings of idle running regulator (13), the worm gear 37 on regulator shaft 35 rotates, and makes clutch 38 servo-actuateds by second rotary block 32 (Fig. 2,5), thus also servo-actuated of throttle plate pin 16.Therefore, throttle plate pin 16 is against the reposition force rotation of Returnning spring 26, and at this moment, for the adjusting of dallying, closure 15 is suitably opened duct segments 14.As already mentioned, be a safety catch at the radially convex shoulder 252 of 25 li of rope sheave 23 inside grooves, restriction throttle plate pin 16 rotatablely moves when motor 33 wrong controls.When normal operation, according to the maximal regulated stroke of software mode restriction motor 33.

In order to make clutch 38 servo-actuateds rotation by worm gear 37, at worm gear 37 in the front of clutch 38, an axial notch 39 or an axial gap are arranged, groove or breach in worm gear 37 fronts, rotation angle range at least 90 ° of circumferencial directions extends the maximum angle of swing of throttle plate pin 16 when this angular range is equivalent to operate accelerator pedal 10.Axial notch 39 passes through radially convex shoulder 391 (Fig. 2, a 5) restriction at circumferencial direction one end.When not operating accelerator pedal 10, a flange 40 (Fig. 2,6) that stretches out clutch device 381 is close to radially convex shoulder 391 under the effect of Returnning spring 26.Like this, radially convex shoulder 391 has constituted second rotary block 32 so that throttle plate pin 16 is rotated by electronic idle running regulator 13 servo-actuateds.

Fig. 6 shows the acting in conjunction of first clutch spare 381 with the second clutch spare 382 of clutch 38.For the purpose of more clearly, in Fig. 6, do not provide the part that idle running regulator 13 surrounds clutch 38 again.Fig. 6 b shows clutch 38 from this side of visual direction identical with Fig. 2, and the visual direction that Fig. 6 a indicates the Via mark from Fig. 6 b shows the perspective view of clutch 38.

As shown in fig. 6, clutch device 381 has been made disc.The first clutch spare 381 of clutch 38 is that rotation is fixed and is axially fixed on the regulator shaft 35.Clutch device 381 has an axial gap (through hole) 41 that with regulator shaft 35 radial spacing is arranged and dispose.See at circumferencial direction, on disc clutch device 381, formed flange 40 with breach 41 adjacency.On first clutch spare 381, fixed the jump ring 42 of a clamp-shaped.Jump ring 42 has the first clamp leg 421 and the second clamp leg 422.The first clamp leg, 421 gap crossings 41.According to fixed-site on second axle head 162 of throttle plate pin 16, the second clutch spare 382 (Fig. 1,2) in the die casting preferably, also have one with throttle plate pin 16 have the configuration of radial spacing ground, axially stretch out the clutch finger 43 (Fig. 1,2) of axle head.The radial spacing of clutch finger 43 and the axis of throttle plate pin 16 is equivalent to the radial spacing of breach 41 and the axis of regulator shaft 3 in first clutch spare 381, like this, when governor body 12 was connected with throttling housing 11 flanges, the clutch finger 43 of second clutch spare 382 passed breach 41.Here, clutch finger 43 clamps between the clamp leg 421 of jump ring 42 and flange 40.Clamp leg 422 is bearing in the side (Fig. 6) of flange 40 towards breach 41.The clutch finger 43 that clamp leg 421 will have an elastic prestress is pressed to the radial side towards breach of flange.For clutch finger 43 when the regulator 13 that will dally is installed to throttling housing 11 can stretch into flange 40 and the clamp leg 421 that clamps facing to flange 40 elasticity between breach in, on clutch finger 43, have a slope 431 (Fig. 6 a, 6b).Adopt jump ring 42, between the flange 40 of the clutch finger 43 of second clutch spare 382 and first clutch spare 381, formed connection very close to each other, that transmit power between throttle plate pin 16 and the regulator shaft 35.First clutch spare 381 is connected with axial restraint with regulator shaft 35 rotations are fixing.In the axial notch 39 in the flange 40 insertion worm gears 37 of this side, the radially convex shoulder 391 with second rotary block 32 concurs together there.The flange 40 that inserts the first clutch spare 381 of 39 li of worm gear 37 grooves has guaranteed: before idle running regulator 13 is installed on the throttling housing 11, do not allow clutch device 381 not rotate.

Governor body 12 is sealing with a potentiometer lid 45 with a housing lid 44 and its back side on the front of throttling housing 11.In housing lid 44, constituted a sliding bearing 46 and in potentiometer lid 45, formed one therewith at the sliding bearing 47 of same straight line.Regulator shaft 35 can be installed in two sliding bearings 46,47 rotatably.Potentiometer lid 45 glues in the governor body 12.Housing lid 44 is connected with governor body 12 by nose fixed block.Housing lid 44 has a positioning hole 48 at it on the front of throttling housing, this positioning hole is consistent with location adapter 49 (shown in Figure 2) on the throttling housing 11.When governor body 12 connected with throttling housing 11 flanges, location adapter 49 shapes were reasonably inserted in the positioning hole 48 and governor body 12 and are fixed on the throttling housing 11, and by this, the axis of throttle plate pin 16 and regulator shaft 35 aligns reliably.Embodiment also can change like this, in order to center, on governor body 12 around convex shoulder insert on the throttling housing 11 around opening in.For governor body 12 is fixed on the throttling housing 11, not only constituting fixed hole consistent with each other 50 or 51 on the throttling housing 11 but also on governor body 12, they interfix by the screw connection.Three the pre-determined constant holes 51 (Fig. 3) altogether that on governor body 12, exemplarily illustrate, constituted a fixedly casement (Lochmuster), it is unified fixing, and according to its breach 41, first clutch spare 381 unified being fixed on the predetermined rotary angle position.Fixedly casement on governor body 12 is unified, is installed on which kind of throttling housing of which kind of internal-combustion engine with idle running regulator 13 to have no relations.The fixedly casement that forms by the fixed hole on the throttling housing 11 50, aspect the configuration of each fixed hole 50, interfix, yet, fixedly casement throttling housing 11 rotations relatively always of designed this, like this, when being put into governor body 12 on the throttling housing 11, governor body 12 relative throttling housings 11 occupy certain, a desirable rotational position.Here, by on throttling housing 11, suitably disposing the casement of fixed hole 50, governor body 12 can occupy each rotary angle position to throttling housing 11, like this, throttling arrangement can be all best with automobile in existing limited installing space be complementary.Second clutch spare 382 on throttle plate pin 16, in the illustrated embodiment, this clutch device 382 has constituted the rotatable clutch 43 that is inserted on the throttle plate pin 16 and inserts in the breach 41, must be according to the casement of fixed hole 50 rotation of relative throttling housing 11 rotate equally, and in the end effectively be pressed onto on the throttle plate pin 16 in the rotational position, like this, pass through fixed hole 50 at governor body 12 and throttling housing 11, when two casements of 51 engaged, clutch finger 43 can correctly be coupled to the breach in the clutch device 381 and can pass this breach.Sensing closure 15 adjustment stroke in order to regulate by motor 33 idle running and when regulating travelling speeds by accelerator pedal 10 have been installed a potentiometer 52 or 53 (Fig. 2 and 5) respectively.Potentiometer 53 is by the position of regulator shaft 35 sensing closures 15, and potentiometer 52 sensing worm gears 37 are with the position of second block 32.Whether adjusting is dallied, and can determine by contrasting two potentiometers 52 and 53.When regulating idle running by idle running regulator 13, can be by two potentiometers 52 and 53 angular orientations of grasping closure 15.As shown in Figure 2, these two potentiometers, 52,53 integrated being installed in the governor body 12.Here, two potentiometers 52 and 53 resistive conductor rail are installed on the common substrate 54 as the printed conductor of circular arc, when 13 assemblings of idle running regulator, substrate 54 is put on the supporting surface (bearing) predetermined in the governor body 12, puts potentiometer lid 45 then.In one procedure, substrate 54 is bonded together with governor cap 12 with printed conductor and potentiometer lid 45.The potentiometer tap and regulator shaft 35 concentric arrangement (Fig. 2) as jockey 521,531 formations of potentiometer 52,53.Each jockey 521 or 531 touches spring 55 and 56 or 57 and 58 with two and is pressed onto together on on-chip two concentric circular arc printed conductors.The jockey 521 of the potentiometer 52 of reconciling of being used to dally rotatably is seated on the regulator shaft 35 and regularly such as by welding, connect with worm gear 37, and the jockey rotation that is used for the potentiometer 53 of sensing throttle position is seated in regulator shaft 35 regularly.Potentiometer 52 and 53 and multipole contact plugs 59 (Fig. 1 and 3) the same with motor 33, by contact plug power, the control and the measured value inquiry of motor 33.

By means of at the schematic representation shown in Fig. 5, the most clearly introduced the working principle of illustrated throttling arrangement.The parts that illustrate in the diagram are equivalent to the parts of explanation among Fig. 1-4 and indicate identical reference symbol.When not operating accelerator pedal 10 and cut off idle running regulator 13, actuator 21 or rope sheave 23 (Fig. 1) are close to the block 28 of throttling housing 11 under the effect of Returnning spring 27 (torsion spring 30), simultaneously, Returnning spring 26 (torsion spring 29) is tractive servo-actuated cover 24 in the direction opposite with first rotary block 31, by this, flange 40 or clutch finger 43 also are close to the rotary block 32 on the radially convex shoulder 391 of worm gearing 34 of automatic brake simultaneously.Because worm gearing 34 automatic brakes, need not operating electrical machines 33, worm gear 37 just is fixed on the certain position, and by rotary block 32 and clutch 38, this is equivalent to certain idle running aperture position of closure 15.If wish that now certain change is done in adjusting to idling of IC engine, then the motor 33 of corresponding operating idle running regulator 13.This is by worm screw 36 rotation worm gears 37, and worm gear 37 makes throttle plate pin 16 rotate round certain angle of swing by second rotary block 32 and clutch 38, and by this fine adjustment valve 15.According to the operation of motor 33, say exactly, according to the sense of rotation of motor 33 driven shafts, by this open or closing direction in the adjusting of closure 15 is worked.Along with the rotation of worm gear 37, the jockey 521 of potentiometer 52 also rotates, and comes the idle running of sensing idle running regulator 13 to regulate by the voltage that reduces in the potentiometer tap, figure 5 illustrates this state.

If operate accelerator pedal 10 now, then, that is to say rope sheave 23 rotations by rope sheave 23 operation actuators 21.As long as the rotary block 31 of rope sheave 23 is run on the follower 241 of servo-actuated cover 24, follower also works together, and by this, throttle plate pin 16 continues rotation in opening direction, and suitably regulates closure 15.By clutch 38, the rotation of throttle plate pin 16 is delivered on the regulator shaft 35.Along with the rotation of regulator shaft 35, jockey 531 rotations of potentiometer 53, sensing is come by the voltage that reduces in the potentiometer tap in the position of throttle plate pin 15.

If accelerator pedal 10 unclamps again, Returnning spring 27 goes back to actuator 21 (rope sheave 23), is close to block 28 on the throttling housing 11 again up to this actuator.Along with resetting of actuator 21, Returnning spring 26 pulls back servo-actuated cover 24, and closure 15 resets.As long as the flange 40 in the clutch device 381 is run into second rotary block 32 in the worm gear 37 again, stop the reverse of throttle plate pin 16 by the worm gearing 34 of automatic brake.From now on, actuator 21 (rope sheave 23) reverse to its till the block on the throttling housing 11.Throttle plate pin 16 and closure 15 occupy the rotational position of being regulated by idle running regulator 13 again.

Slightly have a look, throttling arrangement can be divided into the first parts group 61 (Fig. 5) and the second parts group 62, in Fig. 5, be drawn into a dotted line 60, and this dotted line has symbolically been represented the separatrix of imagination between two parts groups 61,62.The first parts group 61 mainly comprises: the clutch device 382 of throttling housing 11, duct segments 14, closure 15, throttle plate pin 16, actuator 21 (rope sheave 23), Returnning spring 26,27 and clutch 38.The second parts group 62 is equivalent to electronic idle running regulator 13, thereby mainly comprised motor 33, the worm gearing 34 of worm screw 36 and worm gear 37 be housed, on worm gear 37, constituted potentiometer 52, sensing closure 15 positions of radially convex shoulder 391, regulator shaft 35, sensing worm gear 37 positions and sensing rotary block 32 positions of second rotary block 32 potentiometer 53, contact the clutch device 381 of tap 59 (Fig. 1,3) and clutch 38.

The second parts group 62 (electronic idle running regulator 13) can be made separately, stores and supply, and does not rely on the first parts group.Need not revise the second parts group, 62, the first parts groups 61 can be complementary with the internal-combustion engine that will control under individual cases as required.Here, the second parts group 62 (electronic idle running regulator 13) does not need to revise, and therefore, the second parts group 62 can reasonably be made in enormous quantities.

Because by clutch 38, the position of closure 15 is passed to the potentiometer that is configured in the second parts group 62, on the first parts group 61, does not need to electrically contact very close to each otherly.The power supply of two potentiometers 52,53 and motor 33 is connected, and can collect in (Fig. 1) in the contact plug 59 with simple mode.Because mainly the clutch of being made up of clutch device 381 that is configured in the second parts group 62 and the clutch device 382 that is configured in the first parts group 61 38 is designs like this, the governor body 12 (Fig. 3) that belongs to the second parts group 62, each is according to operational situation, the modification measure that need not take to take a lot of trouble just can be connected on the throttling housing at each arbitrarily angled flange, the result is, not influenced by the place situation, do not need to change electronic idle running regulator 13 (the second parts group 62).According to the clutch 38 of two parts groups 61,62 of performance connection, allow the relative throttling housing of idle running regulator that angular orientation is arbitrarily arranged.Clutch 38 can seamlessly connect between the closure 15 in the potentiometer in the second parts group 62 and the first parts group 61.
