Abstract

The utility model relates to an automobile accelerator safety controller, which provides an automobile accelerator safety control apparatus which can control the automatic close of the engine accelerator when the driver steps on the accelerator (accelerator as brake) by mistake and guarantees no traffic accident caused by wrong stepping of the driver. A main balance wheel and a secondary balance wheel are arranged on a support in the same axle. A projection and a concave groove are matching and arranged in the inner end face of two balance wheels. A stress face of the circle has a sloping angle and an outer side of the circle has a spring. A front accelerator cable and a back accelerator cable are separately connected with the main balance wheel and the secondary balance wheel. When the torsion of between two balance wheels reaches a certain value, two balance wheels will rotate by a certain angle. When the driver steps on the accelerator by mistake, the automatic close of the engine accelerator is controlled by the front accelerator cable and the back accelerator cable, thereby guaranteeing no traffic accident due to wrong stepping by driver.

Description

The gas safety governor

Technical field

The utility model relates to a kind of gas safety governor.

Background technique

New hand drives, tending to mistake during this brake steps on the gas (throttle is worked as brake), this slows down and quickens on the contrary, and the traffic accident that causes because of this situation also often has what is heard, therefore a kind of device that can stop immediately when driver fault misstepping on accelerator engine oil of necessary research.

Summary of the invention

The purpose of this utility model is that a kind of gas safety governor will be provided.

The purpose of this utility model is to realize like this, main escapement and secondary escapement are installed on the axis, and its inner side end has the projection and the groove that can cooperatively interact, and groove and projection circumference stress surface have the oblique angle, there is spring in the escapement outside, and the front and back throttle line is connected with the major-minor escapement respectively.

The utility model major-minor escapement inner side end has the projection and the groove that can cooperatively interact, its circumference stress surface has the oblique angle, there is an escapement to move axially in two escapements, there is spring in its outside, the impacting force of spring can be regulated by nut, in fact it is similar to castellated safety clutch, and it is series between the throttle line of front and back.But the automatically controlled engine throttle closes the traffic accident that the assurance automobile does not cause because of driver fault misstepping on accelerator when driver fault misstepping on accelerator.

Embodiment

Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.

As can be seen from Figure 3, main escapement 2 is sleeved on the axis 8 with secondary escapement 7, major-minor escapement inner side end has the projection and the groove that can cooperatively interact respectively, its circumference stress surface has oblique angle (Fig. 2, shown in Figure 5), main escapement 2 can move axially, there is a spring 3 (also can add a pressure spring in addition in spring 3 in the enforcement, to increase the pressure to escapement) in its outside, and the impacting force of spring 3 can be regulated with nut 9.It is similar to castellated safety clutch, it is to make clutch be in jointing state with spring compression mechanism, because of its circumference stress surface is an oblique angle, the moment of torsion of clutch transmits is big more, the suffered axial force of two escapements is also big more, when moment of torsion increases to axial force and surpasses the impacting force of spring, chimeric projection and groove are pushed open and made clutch separation.Spring 3 both can promote main escapement 2 and compress secondary escapement 7, can drive main escapement 2 again and reverse several angle around axle.Major and minor escapement arc outer rim has the serving groove, and an end of preceding throttle line 1 is connected with main escapement 2, and end is connected with gas pedal in addition; Back throttle line 4 one ends are connected with secondary escapement 7, and end is connected with engine oil-valve operation arm or escapement in addition.

Among Fig. 1, secondary escapement is in after the main escapement 2, is drawn as sketch as shown in Figure 6A, and working principle resolves into Fig. 6 B and Fig. 6 C to it for convenience of explanation.

During open out, main escapement 2 does not go to extreme right position (shown in Fig. 6 B) under the effect of torsion spring 3, and this moment, gas pedal was in the extreme higher position of movable stroke; Secondary escapement 7 is under the effect of engine throttle return spring, also be pulled to extreme right position (shown in Fig. 6 C) by back throttle line 4, the projection of main escapement interior edge face is over against the groove of secondary escapement interior edge face at this moment, under the promotion of spring shown in Figure 23, embed groove (shown in Fig. 5 A), the clutch between the major-minor escapement.

When needing open out, depress gas pedal, as shown in Figure 7, by main escapement 2 left side pendulum of preceding throttle line 1 pulling, because the clutch between the major-minor escapement, main escapement 2 drives secondary escapement 7 and swings synchronously, preceding throttle line 1 drives back throttle line 4 and is synchronized with the movement the Push And Release of maneuvering engine throttle.

Drive a car, normally handle throttle, the foot throttle pedal is light and slow, works as mis-accelerator pressing, steps on the gas by the dynamics that touches on the brake, and it is heavy, anxious that pin is added in the dynamics of gas pedal, and this power passes to main escapement 2 by preceding throttle line 1.Secondary escapement 7 has constant weight, and because of effect of inertia, the main escapement 2 of swing rapidly suddenly drives secondary escapement 7 will bigger torsion, and when torsion increased to the escapement axial thrust load and surpasses the impacting force of spring 3, main escapement 2 is outer to move clutch separation (shown in Fig. 5 B).Though the driver slams gas pedal, main escapement 2 is pulled to Fig. 8 B position, and because of clutch separation, secondary escapement 7 is not subjected to main escapement 2 restrictions, and throttle can be closed under the effect of return spring automatically, cuts off the fuel feeding (except the idling oil) to motor.Unclamp gas pedal, main escapement 2 is back to extreme right position under the reversing of spring 3, and its interior edge face projection embeds the groove (clutch) of secondary escapement interior edge face again, is back to situation shown in Figure 6, prepares for refueling next time.

Claims

1. gas safety governor, it is characterized in that being coaxially installed with on the support main escapement and secondary escapement, two escapement inner side ends have the projection and the groove that can cooperatively interact, and its circumference stress surface has the oblique angle, there is spring in the outside, and the front and back throttle line is connected with secondary escapement with main escapement respectively.
