Description

The gas brake equipment

Technical field

The utility model relates to a kind of automobile braking device, the throttle brake equipment during especially a kind of braking automobile mis-accelerator pressing.

Background technology

Along with China's rapid economic development, living standards of the people improve constantly, purchasing power constantly strengthens, and automobile " is come into " common people family more and more.In recent years, China's automobile volume of holding linearly rose, and had now broken through several ten million.Along with the development of auto trade, the safety problem of vehicle drive also shows especially out day by day, and especially the driver maloperation takes place in driving procedure is caused traffic accident to happen occasionally, and has caused showing great attention to of society.

Automobile accelerator pedal and brake pedal all are to be replaced respectively by a pin to realize control at present, this causes new hand for driving a car and old driver off one's guard in that be in an emergency on the run must glancing impact easily, and mistake is used Das Gaspedal and got into an accident as brake pedal.

In the prior art, the patent of mis-accelerator pressing when also having some to prevent brake driver, such as publication number CN101318502, a kind of mis-accelerator pressing emergency braking mechanism of being announced, a kind of mis-accelerator pressing emergency braking mechanism of being announced of publication number CN201240369 for another example, it all can play the effect of emergency braking behind certain mis-accelerator pressing, but these existing technology, all have the product structure complexity, cause cost too high, defective that can't big standard utilization in practice.

The utility model content

Technical problem to be solved in the utility model is, gas brake equipment when a kind of braking automobile mis-accelerator pressing simple in structure, with low cost is provided in order to overcome above-mentioned the deficiencies in the prior art can prevent driver's mis-accelerator pressing when automobile needs emergency braking and gets into an accident.

For achieving the above object, the technical scheme that the utility model adopted is:

A kind of gas brake equipment, its characteristics are, comprise the drawstring that an end links to each other with Das Gaspedal or pedal rod, be arranged at the actuating unit of stepping on rightabout vehicle body under the Das Gaspedal, described actuating unit comprises a rotating shaft, the sheathed ratchet that is fixed with in rotating shaft two ends, the lower end that is connected two oval races is shelved in described rotating shaft rotationally by two end ratchets, the upper end of race is provided with the inner chamber with described ratchet external form coupling, the other end of described drawstring is intertwined and connected in rotating shaft, also be provided with retracing spring in the described rotating shaft, the application force torque direction of retracing spring countershaft is opposite with drawstring just, is used for resetting of drawstring.

The contriver considers that when the normal step on the accelerator of automobile, the application of force is comparatively slow, and when anything crops up so when needing emergency brake, be violent pedal, based on the two difference and the design-calculated the technical solution of the utility model.The utility model is installed on the gas, when automobile normal running, lentamente under the situation of step on the accelerator, Das Gaspedal is stepped on downwards, the pulling drawstring stretches, and slow rotation can be unrestricted in the race lower end for the rotating shaft in the actuating unit, and this moment, throttle can normally use.When chance emergency episode brake miss-stamping is throttle, this moment, throttle was stressed suddenly, because drawstring is to be wrapped in the rotating shaft, when the violent tension tensile force of belt of rotating shaft, the rotating shaft meeting is upwards beated along oval race, and the upper end that makes the ratchet at rotating shaft two ends rise to race cooperates and stings with its inner chamber and fastens, this has just limited the rotation of rotating shaft, this moment, throttle was just stepped on to be gone down under the effect of drawstring, got final product immediate response when motionless and came and change and touch on the brake so step on when driver's mis-accelerator pressing, thereby avoided the generation of accident.After throttle unclamped, drawstring was no longer stressed, and rotating shaft can drop to the race below by nature, and action of reset spring makes the rotating shaft contrarotation simultaneously, drawstring is twined reset.Action principle of the present utility model and car belt action principle are similar, and broaching tool only needs one to be subjected to promptly to draw with sudden force motionless, and its device reaction agility, has rapidly so just further shortened the operation driver reaction time, has improved travel safety.

As mentioned above, than prior art, the beneficial effect that the technical program has is: 1, the technical program only is made up of conventional members such as simple drawstring, rotating shaft, ratchets, it is simple in structure, with low cost, take up room little and install convenient, help product popularization, popularize.2, the technical program also have be quick on the draw, quick, safe and reliable advantage.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

During concrete enforcement as shown in Figure 1, a kind of gas brake equipment, wherein, comprise the drawstring 1 that an end links to each other with Das Gaspedal, be arranged at the actuating unit 2 of stepping on rightabout vehicle body under the Das Gaspedal, during concrete enforcement, described actuating unit 2 is as Fig. 2, shown in Figure 3, comprise a rotating shaft 3, the sheathed ratchet 4 that is fixed with in rotating shaft 3 two ends, described rotating shaft 3 is shelved the lower end that is connected two oval races 5 rotationally by two end ratchets 4, the upper end of race 5 is provided with the inner chamber 6 with described ratchet external form coupling, and the other end of described drawstring 1 is intertwined and connected in rotating shaft 3, also is provided with retracing spring 7 in the described rotating shaft 3, the application force torque direction of retracing spring 7 countershafts 3 is opposite with drawstring 1 just, is used for resetting of drawstring 1.Described drawstring 1 can adopt flat drawstring as shown in the figure during concrete enforcement, can increase the stressed reaction agility of its rotating shaft 3.

When automobile normal running, under the situation of step on the accelerator, Das Gaspedal is stepped on downwards lentamente, and pulling drawstring 1 stretches, and the rotating shaft 3 in the actuating unit 2 can be unrestricted in the slow rotation in race 5 lower ends, and this moment, throttle can normally use.When chance emergency episode brake miss-stamping is throttle, this moment, throttle was stressed suddenly, because drawstring 1 is to be wrapped in the rotating shaft 3, when rotating shaft 3 is subjected to drawstring 1 pulling force suddenly, rotating shaft 3 can upwards be beated along oval race 5, the upper end that makes the ratchet 4 at rotating shaft 3 two ends rise to race 5 cooperates and stings with its inner chamber 6 and fastens, this has just limited the rotation of rotating shaft 3, this moment, throttle was just stepped on to be gone down under the effect of drawstring 1, so step on when motionless when driver's mis-accelerator pressing and can immediate response to come and change and touch on the brake, thereby avoided the generation of accident.

Claims

1, a kind of gas brake equipment, it is characterized in that, comprise the drawstring that an end links to each other with Das Gaspedal or pedal rod, be arranged at and step on rightabout actuating unit under the Das Gaspedal, described actuating unit comprises a rotating shaft, the sheathed ratchet that is fixed with in rotating shaft two ends, the lower end that is connected two oval races is shelved in described rotating shaft rotationally by two end ratchets, the upper end of race is provided with the inner chamber with described ratchet external form coupling, the other end of described drawstring is intertwined and connected in rotating shaft, also is provided with retracing spring in the described rotating shaft.
