Wherein, 1-central control unit, 2-actuating motor, 3-sheath, 4-guiding trestle, the spacing wire drawing of 5-, 6-throttle fork, 7-accelerator drawing, 8-gas pedal assembly, 9-sensor of speed odometer for vehicle.
Embodiment
Below in conjunction with accompanying drawing the utility model is further explained explanation:
With reference to Fig. 1, the input end of central control unit 1 is connected with sensor of speed odometer for vehicle 9, output terminal is final controlling element with actuating motor 2() be connected, the actuating station of actuating motor 2 is connected (all can be flexibly connected or be fixedly connected with) through spacing wire drawing 5 with throttle fork 6, gas pedal assembly 8 also is connected with throttle fork 6 through accelerator drawing 7, described accelerator drawing 7 and spacing wire drawing 5 lay respectively at the both sides of throttle fork 6, and its active force is opposite.Described spacing wire drawing 5 is passed guiding trestle 4 and is connected with throttle fork 6, and described guiding trestle 4 is installed in (consistent with the vibrations of motor to guarantee) on the motor, is used for avoiding it that skew of convolution and movement direction occurs to spacing wire drawing 5 guiding and spacing.Can also be set with sheath 3 in the described spacing wire drawing 5 to protect spacing wire drawing 5, play and reduce spacing wire drawing 5 wearing and tearing and be the effect of its guiding.
During installation, spacing wire drawing 5 one ends are connected with the actuating station of actuating motor 2, the other end passes the mounting hole on the throttle fork 6, accelerator pedal is to maximum position simultaneously, then cut off unnecessary wire drawing and make spacing wire drawing 5 and throttle fork 6 fixing (growing up in the locked spacing wire drawing 5 of the limiting stopper in throttle fork 6 mounting hole apertures such as available maximum diameter, avoid it by deviating from the mounting hole, spacing wire drawing 5 directly is fixedly connected with) with throttle fork 6, need to guarantee that the moving direction of spacing wire drawing 5 is opposite with the moving direction of accelerator drawing 7, simultaneously spacing wire drawing 5 can not interfere gas pedal assembly 8 in the motion of setting below the highest speed, can not affect the movement travel of gas pedal maximum.
Working principle:
Vehicles failed starts, and when gas pedal assembly 8 did not press down, actuating motor 2 was not worked, and throttle fork 6 is positioned at initial position A, and spacing wire drawing 5 is relaxed state; When the driver steps on the throttle pedal assembly 8, accelerator drawing 5 drives throttle fork 6 to a side, the corresponding lifting of the speed of a motor vehicle, vehicle speed signal (digital signal) is reached central control unit 1 synchronously, central control unit 1 speed limit scope predefined with it (be 70-75 kilometer/hour as setting speed limit) compares judgement, when the speed of a motor vehicle does not reach the speed limit scope of setting, then do not export control signal to actuating motor 2, spacing backguy 5 still is in relaxed state, and is not spacing to throttle fork 6; When driver's pedal assembly 8 that continues to step on the throttle, the speed of a motor vehicle continues to promote, reach lower in limited time (70 kilometers/hour) of speed of a motor vehicle speed limit when the speed of a motor vehicle, throttle fork 6 is swung by the maximum position B place of accelerator drawing 7 with trend throttle fork, spacing wire drawing 5 retraction tension force increase and tension, central control unit 1 receives corresponding vehicle speed signal simultaneously, through conversion, relatively, the output control signal is to actuating motor 2 after judging, actuating motor 2 actuating station work, strain spacing wire drawing 5 in the other direction, the swing angle of release that spacing wire drawing 5 overcomes the active force restriction throttle fork 6 of accelerator drawing 7 continues to become large; The pedal assembly 8 if driver continues to step on the throttle, the speed of a motor vehicle further is promoted to peak (75 kilometers/hour), accelerator drawing 7 drives throttle fork 6 pendulum setting maximum position B extremely, then spacing wire drawing 5 further is tightened up, tension force continues to increase, vehicle speed signal is admitted to central control unit 1 simultaneously, central control unit 1 sends control signal to actuating motor 2, actuating motor 2 work, make the powerful travelling backwards of its actuating station, drive spacing wire drawing 5 to position A direction pulling throttle fork 6, the speed of a motor vehicle is down to below the peak of speed limit scope.
Central control unit 1 can be according to the reversal interlocking relay that changes simultaneously control actuating motor 2 according to actual vehicle speed, and the assurance speed limit steadily avoids the speed of a motor vehicle to surpass the speed limit scope simultaneously.When the speed of a motor vehicle is between speed limit scope lower limit and the upper limit (such as 70 kilometers/hour to 75 kilometers/hour), central control unit 1 will carry out adjustment according to the speed of a motor vehicle and acceleration situation, export corresponding control signal to step actuating motor 2, make it make its corresponding swing with the fuel injection quantity of control Injection Pump to the spacing wire drawing 5 corresponding pulling force of generation and conduction to throttle fork 6, avoid the speed of a motor vehicle to surmount the speed limit range limit.When driver's close the throttle assembly 8, the speed of a motor vehicle is down to the speed limit scope when following (as below 70 kilometers/hour), and central control unit 1 output control signal then stops after making the actuating station of actuating motor 2 move to the home position.Realize intelligent speed-limiting according to above-mentioned controlling method.
