Abstract

The invention provides an automobile emergency safety hood with an alternate name of automobile emergency safety brake, which is manufactured based on a reduction gear used in the situation that maintenance angular cleats of an automobile and an aircraft carrier-based plane descend. The automobile emergency safety hood is used in the automobile emergency by releasing positioners which are similar to the maintenance angular cleats. The positioners reach the front of rear wheels under the action of gravity and a pulling cable (also known as a positioning cable), so that the two rear wheels of the automobile are compactly pressed on the positioners, thereby greatly increasing the friction between the automobile and the ground and greatly reducing the braking distance of the automobile in emergency, as if a pair of horse stopped stones is imbedded at the front of the real wheels of the automobile, under the action of self-brake of the automobile and the emergency safety hood, emergency safety brake performance of the automobile is greatly improved, and in particular under the condition that the self-brake of the automobile is out of control, a good braking effect is performed. The automobile emergency safety hood of the invention comprises a controller, the positioner, the pulling cable and other components.

Description

The automobile emergency condom

Technical field: the invention belongs to a kind of automobile emergency safety arrestment technology.

Background technology: existing braking automobile braking technology, vehicle maintenance and repair cleat and automobile mechanical, electronic, steam-operating braking technology.

Summary of the invention: there is braking situation out of control once in a while in existing automobile brake technology, when automobile speed is too high, poor stop, still cause car accedent, and the present invention is as a kind of auxiliary device of automobile brake, at automobile in case of emergency, can finish automobile brake in short distance with original brake system of automobile, perhaps at the bus stop under the car brake system situation out of control, making automobile finish braking stops automobile, can significantly reduce the incidence of traffic accident, principle of the present invention is in case of emergency, adopt a kind of particular form, increase automobile and ground-surface frictional area and friction coefficient, increased automobile and ground-surface friction force greatly, between automobile and ground, had one to block thing again simultaneously, make automobile be stopped the origin of core of the present invention that Here it is and automobile emergency condom in short distance.

Technical scheme: use controller, steady arm and trailing cable or the like constitute the automobile emergency condom or make the automobile emergency safety brake solve the problem of automobile emergency glancing impact, the automobile emergency condom is under people's control, by machinery, electronic, or hydraulically operated mode release-push, constitute controller, steady arm is fallen earthward, the same height of steady arm is about wheel diameter, bottom side length is less than the rear wheel diameter width greater than the formula radius of wheel, for the two-fold cleat of wheel width forms through improving, steady arm is under the effect of gravity and traction, bearing before rear wheel falls to two trailing wheel fwd ground, the rear wheel that is advanced presses, and the profile of steady arm makes urgent being attached on preceding bottom of automobile back wheel and the ground of steady arm, make steady arm make progress stressed be slightly larger than automobile or equal automobile press to the gravity of steady arm (being preferably less than the gravity that automobile is pressed to steady arm) and make automobile under the effect of steady arm, do not cause automobile back wheel to be upwarded pressure and turn over before producing, the friction force of steady arm can reach maximum suburb fruit like this, has reduced the incidence of accident greatly.Though but behind such emergency braking wheel shaft is had certain damage, but compare the safety of automobile, just be nothing, can overhaul again wheel shaft and reach safety rate, the effect of trailing cable is exactly in the automobile emergency braking procedure, in the process that steady arm falls, with automobile position is guided steady arm on the road surface before the automobile back wheel into, steady arm one end hangs on the automobile of rear wheel top, and an end is hung on respectively on the center of gravity line on steady arm both sides.

Description of drawings: Fig. 1 is a schematic diagram, and the garden is the wheel scheme drawing.

Fig. 2 is the steady arm plan view, and A is the tractor clip, and B is two steady arm clips, and h is the steady arm height, and R is the trailing wheel radius.

Fig. 3 is the automobile emergency condom scheme drawing of mechanical control method.

The specific embodiment: automobile emergency condom embodiment as follows:

1, controller: controller is by mechanical control method, the mode of electronic mode or steam-operating control by people's the hand or the Spring lock catch switch of pin opening controller release fixer, falls steady arm, and during fixed locator, only need draw back rim lock the steady arm snap close has been buckled just.

2, steady arm: it is that rectangular bucking ladder constitutes by a bottom, see that the trapezoidal bottom side length in accompanying drawing 2 sides is that the rear wheel radius is to length between the wheel diameter, height is about 3/4ths height of radius of wheel, acute angle between the domatic and ground of trapezoidal faces at 40 degree between 70 degree, the bucking ladder width is two wheel width, arc face by radius is replaced with the wheel by one for two to three centimetres domatic at the adverse grade identity distance of steady arm bottom and top, the front of steady arm is one domatic, the center of gravity line top of side trapezoidal faces has a make-up to be the traction claim-reduction, there are two adjacent buckling to be steady arm fixing snap close, steady arm available iron and wooden work at the steady arm top.

3, trailing cable: be connected to an iron chains by iron wire loop, the iron chains center fixation is on the front upper part automobile of rear wheel, and in addition two ends are fixed on the steady arm two ends, and length is anchored to traction vapour and has a small surplus under the rear wheel and can.

During use, start the controller of automobile emergency safety brake with hand or pin, controller switches discharges, under two effects of steady arm of the preceding fixed position of automobile back wheel, fall earthward at gravity, when ground, trailing cable is tightened with automobile position, steady arm is placed on the ground before the automobile back wheel, rolled by automobile back wheel, thereby produce bigger friction force, like having put a pair of horse that blocks in the automobile front, make automobile obtain a kind of safety control, device although it is so can produce certain infringement to vehicle wheel shaft, but this infringement is recoverable afterwards, compare safety, safety is only primary, and preferred mechanical formula automobile emergency safety brake is seen accompanying drawing 3.

Claims

The automobile emergency condom cry again the automobile emergency safety brake be with a steady arm that is similar to the vehicle maintenance and repair cleat in case of emergency the start-up control device open the steady arm snap close and discharge steady arm, steady arm enters automobile back wheel under the traction of gravity and traction before, pressed the bigger friction force of generation by automobile back wheel and act on automobile back wheel, automobile is stopped faster, and it and automobile brake system use when emergency situation simultaneously.It blocks horse to automobile brake system and highway limit similar feature, and the feature of automobile emergency condom is:

(1), as the usefulness of emergency situation braking.
