Abstract

The present invention relates to an accelerating and braking combined pedal for vehicles. The upper part of a braking pedal is hinged with a fixing bracket; a releasable movable connection is formed between the braking pedal and the fixing bracket via a magnetic attracting assembly on the upper end of the braking pedal. A reset piece of the braking pedal is arranged between the braking pedal and the fixing bracket. The braking pedal and an accelerating pedal are arranged in front and back, and the lower parts of the both pedals are hinged via a lower hinged shaft. A reset piece of the accelerating pedal is arranged between the braking pedal and the accelerating pedal. The shaft body of the lower hinged shaft, in the braking pedal, is successively provided with a rope pulley, a retainer ring, a drive assembly and a movable shaft assembly, wherein a stop block contacts the outer end of a movable shaft in the movable shaft assembly. The fixing support and the stop block are arranged on the upper and the lower parts of a carriage plate on the front side of a cab, so that the existing braking lever contacts the middle of the braking pedal, and the back end of the existing throttle pull rope contacts the circumference surface of the rope pulley, so the combined pedal can be used. As long as the accelerating pedal is persistently and rapidly stepped down, an oil supply state can be rapidly converted into a braking state so as to ensure driving safety.

The movable axis assembly is by bearing pin 18, movable axis 8 is formed, the right side of following jointed shaft 6 has axial counterbore 6a, have two front and back that communicate with counterbore 6a to groove hole 6b corresponding to section place, a counterbore 6a left side on the circumferential side wall of following jointed shaft 6, movable axis 8 can be inserted among the counterbore 6a with moving axially and its right-hand member stretches out in the jointed shaft 6 down certainly, bearing pin 18 stretches out in two slotted eye 6b with its rear and front end, the vertical affixed back of left side section of movable axis 8, the two ends of bearing pin 18 are between the circumferential bottom surface of the circumferential bottom surface of preceding vallecular cavity 17d and back vallecular cavity 17b, bearing pin 18 can move axially along two slotted eye 6b, and bearing pin 18 reclines mutually with the side, right side of rotation displacement body 17;

The block 9 that is fixed on truck board A bottom contacts with the right-hand member of movable axis 8, is 3.2 times of movable axis 8 external diameters with the length of the contacted plane of action 9a of movable axis 8 right-hand members on the block 9, and the height of plane of action 9a is 1.4 times of movable axis 8 external diameters.

Principle of work of the present invention is as follows:

When normal driving, the plane of action 9a of the right-hand member of movable axis 8 and block 9 keeps in touch, as long as 1 it is rotated towards the direction of truck board A around following jointed shaft 6 to put one's foot down, spring 5 just obtains stretching, all the time the trundle 1c that inserts on the acceleration pedal 1 among the vallecular cavity 17b of back just drives 17 rotations of rotation displacement body, reach among the rotation jack 14b because of following the rotation displacement body 17 synchronous bearing pins 19 that rotate, so will drive rope sheave 14 rotates, the throttle stay cord 13 that is connected on rope sheave 14 peripheries is tightened to open the acceleration pedal operating mechanism, realize fuel feeding, the vehicle motor high-speed motion quickens vehicle;

Need glancing impact in the driving, only need continue to put one's foot down 1, make the right-hand member of movable axis 8 no longer contact first with the plane of action 9a of block 9, the elastic force that stage clip 16 is released makes rotation displacement body 17, bearing pin 19, bearing pin 18, movable axis 8 moves right, make bearing pin 19 fall back on and rotate outside the jack 14b, the rope sheave 14 that loses constraint rotates round about, throttle stay cord 13 is loosened, self-return is to close the acceleration pedal operating mechanism, stop control lever, vehicle motor microinching immediately makes car retardation, at this moment, though acceleration pedal 1 is being stepped on its uncontrollable rope sheave 14 and lose the fuel feeding effect; Second making acceleration pedal 1 and brake pedal 2 recline (is that acceleration pedal 1 is urged to brake pedal 2, at this moment, spring 5 is stretched to end position), and be released from fixed support 3 by brake pedal 2 upper ends by means of the magnetic attracting assembly, the acceleration pedal 1 final brake pedal 2 that drives rotates around last jointed shaft 4, the upper end that makes brake pedal 2 gradually away from truck board A the lower end gradually near truck board A, make torsion spring 12 obtain distortion, and brake pedal 2 will be oppressed brake lever B, make brake lever B move towards headstock direction (promptly forward), allow the brake pedal operating mechanism move, make vehicle obtain braking, at this moment, brake pedal 2 plays brake action;

When wanting brake off, only need no longer step on acceleration pedal 1, stopping its compressing to brake pedal 2 gets final product, this process is summarized as follows: when acceleration pedal 1 is no longer stepped on, brake pedal 2 under the resilient force that torsion spring 12 is released around on jointed shaft 4 backward rotation, its upper end gradually near truck board A and lower end gradually away from truck board A, make brake pedal 2 upper ends by means of forming active connection that can discharge between magnetic attracting assembly and the fixed support 3 once more first, second make brake pedal 2 no longer oppress brake lever B, brake lever B will be towards direction (promptly backward) motion of operator's compartment, the brake pedal operating mechanism can't be moved, at this moment, brake pedal 2 does not just have brake action.In the process of brake off, for acceleration pedal 1, because of it is hinged on the bottom of brake pedal 2, acceleration pedal 1 will followed the backward rotation of brake pedal 2 gradually away from truck board A, in addition because the return action of spring 5, allow also backward rotation and resetting of acceleration pedal 1, make the right-hand member of movable axis 8 and the plane of action 9a of block 9 keep in touch once more, like this, rotation displacement body 17, bearing pin 19, bearing pin 18, movable axis 8 will be moved to the left, finally make bearing pin 19 reach once more and rotate among the jack 14b, because of the trundle 1c on the flat pedal 1a is inserted among the vallecular cavity 17b of back all the time, step acceleration pedal 1 and can pass through rotation displacement body 17, bearing pin 19 drives rope sheave 14 and rotates, and makes the throttle stay cord 13 that is connected on rope sheave 14 peripheries can control the acceleration pedal operating mechanism, to realize fuel feeding, can make the self-propelled vehicle can cruising again.

This shows that the present invention will speed up pedal 1, brake pedal 2 is combined, when normal driving, just acceleration pedal 1 plays the effect of control acceleration pedal operating mechanism, and brake pedal 2 can't play a role; When the needs glancing impact, can make its get out of hand effect as long as continue to step acceleration pedal 1, meanwhile, can allow brake pedal 2 bring into play brake actions separately; After the end of braking,, can make brake pedal 2 can't bring into play brake action again rapidly, and only allow acceleration pedal 1 bring into play the fuel feeding effect by means of torsion spring 12, magnetic attracting assembly, spring 5 as long as no longer stepping on acceleration pedal 1.So move in circles, can make the self-propelled vehicle cruising, can make self-propelled vehicle in time obtain braking again.

Above-described only is preferred implementation of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the principle of the invention, can also make some modification and improvement, these also should be considered as belonging to protection scope of the present invention.
