As shown in Figure 2, the 1st throttle plate pin 41 and the 2nd throttle plate pin 42 are arranged point-blank.The 1st throttle plate pin 41 rotates and supports 2 throttler valves 30 in left side of the 1st group freely, and they are opened and closed simultaneously.The 2nd throttle plate pin 42 rotates and supports 2 throttler valves 30 in right side of the 2nd group freely, and they are opened and closed simultaneously.
Because bearing 50 is disposed at every each throttler valve 30 of sandwich, throttle plate pin 41,42 can rotate smoothly, and can prevent distortion, guarantees respectively to organize the action synchronous (carrying out on-off action mutually with same position) of throttler valve 30.Bearing 50 can adopt ball bearing, roller bearing and surface of contact itself to have the various bearings such as cylindrical bearing of bearing function.And, in a plurality of bearings 50, have at least part to adopt not only radially but also at the bearing of axially also playing a supporting role.
As shown in Figures 2 and 3, the 1st driving mechanism 60 by DC motor 61, be fixed on gear 62 on the output shaft 61a, be fixed on the inner end of the 1st throttle plate pin 41 and constitute with the adjustment screw 64 of the stop position of gear 62 meshed gears 63 and regulation gear 63.

As shown in Figures 2 and 3, the 2nd driving mechanism 70 is by DC motor 71, be fixed on the gear 72 on the output shaft 71a, be fixed on the 2nd throttle plate pin 42 inner end and with gear 72 meshed gears 73, and the adjustment screw 74 of the stop position of regulation gear 73 constitutes.
The 2nd Returnning spring 82 be positioned at gear 73 near, it applies 2 throttler valves 30 that kind of rotatory force makes the 2nd group to the 2nd throttle plate pin 42 and resets to and close the side stop position.
When DC motor 71 when halted state begins to rotate, by gear 72 and gear 73, make the 2nd throttle plate pin 42 opposing the 2nd Returnning spring 82 applied forces and rotate the 2nd group 2 throttler valves, 30 complete opening gas-entered passageways 21.On the other hand, if cut off the power supply of DC motor 71, then under the rotatory force effect that the 2nd Returnning spring 82 applies, the 2nd throttle plate pin 42 rotates round about, and 2 throttler valves 30 of the 2nd group reset to the stop position of closing side.
As mentioned above, the 1st driving mechanism 60 and the 2nd driving mechanism 70 comprise train of gearings, because by providing the mode of driving force to be configured to opposed inside end each other, these parts are intensive in central authorities, make device 2 stricturizations, miniaturization with the 1st throttle plate pin 41 and the 2nd throttle plate pin 42.
As shown in Figure 2, the 1st angle detecting sensor 91 and the 2nd angle detecting sensor 92 are the non-contact angle sensors that are disposed at the outboard end separately of the 1st throttle plate pin 41 and the 2nd throttle plate pin 42 respectively, angular position of rotation to throttle plate pin 41,42, promptly, the angular position of rotation of the throttler valve 30 of the angular position of rotation of the 1st group throttler valve 30 and the 2nd group detects, and by angular detection circuit 5,6 to control device 12 output detection signals.
Work to above-mentioned more piece valve gear describes below.
Under common operating mode, DC motor 61,71 bases are rotated to a direction from the control signal of control device 12, and by gear 62,63 and gear 72,73 rotary driving force are delivered to the 1st throttle plate pin 41 and the 2nd throttle plate pin 42.So, the rotatory force that the 1st throttle plate pin 41 and the 2nd throttle plate pin 42 opposing Returnning springs 81,82 apply, beginning is rotated to a direction, and the throttler valve 30 of the 1st group and the 2nd group is from the direction rotation of stop position to gas-entered passageway 21 complete openings.
On the other hand, if DC motor 61,71 is according to rotating round about from the control signal of control device 12, then the 1st throttle plate pin 41 and the 2nd throttle plate pin 42 begin round about to rotate under the rotatory force effect that return spring 81,82 applies, the direction rotation that the throttler valve 30 of the 1st group and the 2nd group is closed to gas-entered passageway 21 from the position of whole unlatchings.If cut off the power supply of DC motor 61,71, the 1st throttle plate pin 41 and the 2nd throttle plate pin 42 quick rotation under the rotatory force effect that Returnning spring 81,82 applies then makes the throttler valve 30 of the 1st group and the 2nd group turn back to stop position.
Promptly, under common operating mode, according to the condition of running load etc., DC motor 61 and 71 simultaneously controlled, throttler valve 30 to the 1st group and the 2nd group carries out driven for opening and closing simultaneously, to keep the optimal aperture to the signal of accelerator angle sensor 13.
Under other situation beyond the common operating mode, when simultaneously the air quantity of all cylinders of motor being adjusted with the driving of same throttler valve, only change the aperture of throttler valve a little, the increase of the air quantity of supplying with to motor just produces very big influence, therefore, if the minute angle to throttler valve is not carried out high-precision adjustment, then be difficult to supply with the air of optimal dose.So driving that need not same throttler valve is adjusted the air quantity of all cylinders simultaneously.For example, make 2 throttler valves in left side 30 of the 1st group keep certain aperture if control a side motor 61, and control the opposing party's DC motor 71 opens and closes the 2nd group right side throttler valve 30, and air quantity is adjusted by the throttler valve of each group, then owing to make one group throttler valve keep certain aperture in advance, compare when simultaneously the air quantity of all cylinders of motor being adjusted with the driving of same throttler valve, the influence of the increase of the air quantity that can supply with to motor is suppressed to inferior limit, thereby supplies with the air of optimal dose.Its result, A/D converter, angle transducer also can not use high performance product, therefore can reduce cost.
Also have, because the length of the state of cooling of motor and outlet pipe is different, the combustion regime of each cylinder of motor is also different.Therefore, as mentioned above, make 2 throttler valves in left side 30 of the 1st group keep certain aperture if control a side motor 61, and control the opposing party's DC motor 71 opens and closes the 2nd group right side throttler valve 30, then can supply with the air of the optimal dose that is fit to combustion regime to each different cylinder of combustion characteristic respectively.
In addition, reach maximum in the aperture of the throttler valve 30 of the 1st group and the 2nd group, when vehicle will suddenly quicken, because of the moment of torsion of motor becomes big suddenly, the driver can be subjected to the anxious influence that brings quickened, and can't guarantee safe driving.In this case, make the 1st group left side throttler valve 30 keep quickening preceding aperture if control a side motor 61, and control the opposing party's DC motor 71 opens and closes the 2nd group right side throttler valve 30 according to the acceleration situation, then because by the air quantity of group adjusting to the motor supply, can relax moment of torsion and become big rapidly, the driver can avoid the influence that anxious acceleration brings, thereby guarantees safe driving.
On the other hand, under idle state,, for example, only suitably drive DC motor 61,, that is, the aperture of the 1st group throttler valve 30 is finely tuned the 1st throttle plate pin 41 according to drive signal from control device 12.
Particularly, when carrying out the idle speed control (ISC) of motor, do not establishing IACV (Idle Air Control Valve) in addition, under the situation of wanting simultaneously the air quantity of all cylinders of motor to be adjusted with the driving of same throttler valve, for the variation of the idling speed that reaches expection, be necessary to carry out the adjustment of atomic little valve valve opening.Therefore, angle transducer, A/D converter also need to adopt high performance product.But, as mentioned above, make 2 throttler valves in left side 30 of the 1st group keep certain aperture if control a side DC motor 61, and control the opposing party's DC motor 71 opens and closes the 2nd group right side throttler valve 30, then owing to make one group throttler valve keep certain aperture in advance, compare when simultaneously the air quantity of all cylinders of motor being adjusted with the driving of same throttler valve, the adjustment that needn't carry out small valve valve opening can be supplied with the corresponding air quantity of variation with the idling speed of expecting, angle transducer, A/D converter also can not use high performance product, therefore can realize cost degradation.In this way, when carrying out idle speed control, also can suitably control the driven for opening and closing of throttler valve 30 by group.
In addition, when having carried out making the operation that throttler valve returns rapidly, according to the drive signal from control device 12, for example, one in the DC motor 61,71 by after the reverse driving, and another is again by reverse driving.That is, one group throttler valve 30 carries out after the closing motion, and the throttler valve 30 of another group then carries out closing motion.Time difference is set like this, and drives throttler valve 30, then can suppress the rapid change of the rotating speed of motor 1, prevent braking nose dive, skid, phenomenon such as overturning, thereby carry out safe driving by group.
On the contrary, make vehicle carry out urgency when quickening, according to the drive signal from control device 12, after in the DC motor 61,71 one was driven, another was driven again.That is, a side throttler valve 30 carries out after the breakdown action, and the throttler valve of another group then carries out breakdown action.Like this, except the aperture that makes a group keeps certain control, the time difference also is set, and drives throttler valve 30 by group, also can suppress the rapid change of the rotating speed of motor 1, the driver can avoid the anxious influence that brings quickened, thereby guarantees safe driving.
Fig. 4 to Fig. 6 represents other embodiment of relevant more piece valve gear of the present invention.Its control system is identical to those shown in Fig. 1.
This device 110 is 4 throttle valve devices that are applicable to V-type 4 Cylinder engines, as Fig. 4 to shown in Figure 6, it have 4 throttle bodies 120 of delimiting gas-entered passageway 121, respectively be disposed at 4 throttler valves the 130, the 1st throttle plate pin 141 and the 2nd throttle plate pin 142 on each gas-entered passageway 121, with identical bearing the 50, the 1st driving mechanism 160 noted earlier and the 2nd driving mechanism the 170, the 1st Returnning spring 181 and the 2nd Returnning spring the 182, the 1st angle detecting sensor 191 and the 2nd angle detecting sensor 192, spacer 200 and connecting plate 210 etc.
In addition, 2 throttle bodies 120 in left side and 2 throttle bodies 120 on right side interconnect by spacer 200 respectively, and its integral body links together securely by connecting plate 210 then.And spacer 200 has run-through channel 201 and assembling recess 202 as shown in Figure 6.
As Fig. 4 and shown in Figure 6, the 1st throttle plate pin 141 and the 2nd throttle plate pin 142 are arranged with certain spaced and parallel.The 1st throttle plate pin 141 rotates and supports 2 throttler valves 130 in left side of the 1st group freely, and they are opened and closed simultaneously.The 2nd throttle plate pin 142 rotates and supports 2 throttler valves 130 in right side of the 2nd group freely, and they are opened and closed simultaneously.
