The specific embodiment

Consult accompanying drawing 1,7.In the illustrated

embodiment

1,2, the right is that interlinked mechanism, the left side are moment speed-raising stop motion mechnism, and the interlinked mechanism in the two is identical, and difference is that moment speed-raising stop motion mechnism adopts different version.

Be example with embodiment 1 below, accompanying drawings course of action of the present utility model and mechanism.

Consult accompanying drawing

1,2,3.In the interlinked mechanism, pull bar 21 outer ends link to each other with Das Gaspedal in the operator's compartment, inner end and transmission slide plate 18 are movably hinged, during the accelerator instead of brake pedal, pull bar 21 is outwards operation shown in Fig. 1 arrow, driving transmission slide plate 18 is that the axle center rotates counterclockwise with suspended axle 19, it is the axle center clickwise with bottom dial axis 22 that dial axis 20 on it drives throttle slide plate 17 by the dial axis chute on the throttle slide plate 17 4, swing to the right at the top of throttle slide plate 17, the open the throttle wide action is sent to the input end of moment speed-raising stop motion mechnism by drag-line 15.

Consult accompanying drawing

1,5,6,7.In the linear motion-type moment speed-raising stop motion mechnism among the embodiment 1, ratchet is pulled 14 tiltably-mounteds in housing, can be by chute 30 along the 32 straight line slippages of two guideposts.Ratchet 11 is supported on claw plate 14 tops by pawl axis 10 rotations, and ratchet, pawl tail correspondence on the corresponding claw plate of pawl point are fixed on the magnetic core 13 in the housing.Orifice plate 29 in the control setup is positioned at claw plate 14 bottoms, among the embodiment 1 with claw plate 14 shared plate bodys.Two orifice plate contact 25 correspondences are positioned on the running orbit of orifice plate 29.Controller 9 is fixed in the housing, and the recognizer control module in it can be bought in the market or be tailor-made, and power supply is the 24V direct supply, and recognizer control module and two orifice plate contacts 25, magnetic core 13 and power supply composition control the road.

Consult accompanying drawing

1,2,3,5,6,7.As everyone knows, the trample action when normally raising speed open the throttle wide is a milder action, and so, sharply trampling when mistake is stepped on just is the improper acceleration of trampling.Moment speed-raising stop motion mechnism is just according to normally trampling and improper speed difference characteristic of the trampling design-calculated of advancing.When throttle slide plate 17 is defeated by moment speed-raising stop motion mechnism by the drag-line 15 at top with the motion of open the throttle wide, claw plate 14 moves to the upper right side under the pulling of drag-line 15, when contacting by the hole that is intervally arranged on the orifice plate 29, two orifice plate contacts 25 send an electric signal to the recognizer control module, the recognizer control module begins self-clocking, if claw plate 14 is in the smooth running of normal open the throttle wide, T in second no electric signal import into, the recognizer control module stops timing, magnetic core 13 keeps "on" position, adhesive ratchet 11 afterbodys still, claw plate 14 keeps quiescences; When mistake trample improper open the throttle wide, the quick slippage of claw plate make T in second two orifice plate contacts contact once more and when the electric signal input is arranged, the recognizer control module is cut off control loop automatically, magnetic core 13 outages, ratchet 11 get out of hands fall, the pawl point snaps in the ratchet, prevent the quick slippage of claw plate in moment, interrupt throttle and strengthen motion; Mistake is afterwards trampled the continuity action and can't be swung to the right because of throttle slide block 17 tops are subjected to the restriction of arrested state claw plate 14, transmission slide plate 18 just drives the rotation of throttle slide plate 17 lower rightward and makes braking return board 6 by dial axis 22 by dial axis 20 is the axle center left-hand revolution with suspended axle 19, brake connects piece 7 and can not rotate by the restriction of spline pin 45 on the braking return board 6, can only be that the axle center rotates counterclockwise synchronously with suspended axle 19 with braking return board 6, brake shoe brake cheek in brake line pulling brake system during rotation on its left side, below connecting bore is implemented braking (bottom-right connecting bore is connected with brake pedal), mistake is trampled the continuity action be converted to the drag motion.After chaufeur recognized that mistake is stepped on and unclamped Das Gaspedal, throttle slide plate 17 and claw plate 14 resetted under the effect of

return spring

24,31 respectively.In the time of 1 second, the automatic conducting control loop of recognizer control module meeting makes magnetic core energising adhesive ratchet heavily again, decontrols claw plate, strengthens operation with the normal throttle of obstruction free by stop for magnetic core 13 outages, ratchet whereabouts ratchet.T numerical value second input is stored in the recognizer control module, on the orifice plate 29 spacing in straight-though arrangement hole should make T in second orifice plate contact 25 can not contact relatively once more, claw plate 14 can not be subjected to stop when guaranteeing normal open the throttle wide.

Consult accompanying drawing

1,5,6.Guidepost 32 quantity be two, Long Circle chute 30 couplings on the thin diameter parts in top and the claw plate 14, extend out the back by the two sliding block joint of packing ring 35, spring collar 36 realizations by chute 30.Pawl axis 10 is fixed on the housing; Two orifice plate contacts 25 are fixed on the contact pillar 26 in the housing by bakelite piece 27, are connected with insulation between the contact pillar to realize the orifice plate contact; On the orifice plate 29 biside plate faces respectively card be covered with insulation strip 37, contact with orifice plate to prevent orifice plate contact 25.Orifice plate contact 25 is the telescopic elastic contact, and its termination is a circular arc, under the elastic force effect, stretch out during hole on the corresponding orifice plate 29 contact, orifice plate operation touching circular arc bounces back during the termination automatically, do not influence the orifice plate slippage.

Consult accompanying drawing 8,9.Among the embodiment 2, moment speed-raising stop motion mechnism is the type of rotatablely moving, its action mechanism is: when the top of throttle slide plate 17 rotates by winding rope 42 driven in rotation velocity limiters 43, coaxial affixed big gear wheel 40 drives pinion in mesh 41 rotations with it, pulling engine throttle line 1, automatic stall when the rotating speed of rotation velocity limiter 43 surpasses setting value stops throttle to increase, the conversion drag of back is with embodiment 1, so repeat no more.Rotation velocity limiter 43 is returned virgin state after unclamping Das Gaspedal.The rotation velocity limiter can be bought in market or be customized.

Consult Fig. 1,2,3,7.The position-limited trough of setting up on the stay bearing plate 16 33 is used to limit the amplitude that throttle slide plate 17 bottoms turn left.Stay bearing plate 16 is fixed in the housing.When setting up stop screw 3, contact switch 38 on it with incorporate the control loop that magnetic core 13, recognizer control module, orifice plate contact 25 and power supply form after indicator lamp 39 is connected in series into, the indication loop that conducting was incorporated into when the contact switch of touching on the stop screw 3 38 was swung at throttle slide plate 17 tops to the right, indicator lamp 39 lights, the indication that Das Gaspedal puts in place when chaufeur sends.Can regulate the position of electric shock switch by screwing stop screw 3.
