The specific embodiment
A kind of energy-storing automobile emergency braking apparatus as shown in Figure 1, comprise two symmetrically arranged brake equipment bodies that are installed on the stepped shaft 10 and are positioned at two longeron 18 outsides of automobile, automobile back wheel 17 the place aheads, described stepped shaft 10 is installed on the longeron 18 by flange 23, described stepped shaft 10 laterally vertically is installed on the longeron 18 and has groove vertically, and each brake equipment body comprises along stepped shaft 10 axially and the volute spring 2 22 and the chain belt wheel 9 that set gradually in longeron 18 outsides; Described volute spring 2 22 the inners are fixed in the groove, the outer end of volute spring 2 22 is installed on the suspension hook 21 that is arranged at longeron 18, the inner end edge of described chain belt wheel 9 is provided with boss 6, described boss 6 is provided with ratchet slot 5, the top of described stepped shaft 10 is provided with ratchet support 24, one end of described ratchet support 24 is fixed on the longeron 18, and the other end of ratchet support 24 is provided with ratchet 4, and described ratchet 4 matches with ratchet slot 5; Described stepped shaft 10 is provided with the key shape block 13 that acts on mutually with boss 6, the outer distolateral volute spring 1 that is provided with of described chain belt wheel 9, the inner of described volute spring 1 is fixed in the groove on the stepped shaft 10, the outer end of volute spring 1 is fixed on the chain belt wheel 9, can be fixed on the chain belt wheel 9 by the outer end of locating dowel pin 12 volute spring 1, be arranged with chain belt 7 on the described chain belt wheel 9, described chain belt 7 can be the moulding chain belt, one end of described chain belt 7 is fixed on the chain belt wheel 9, the other end of chain belt 7 extends to the front lower place of automobile back wheel 17 along the supporting plate 16 that is obliquely installed, and keep suitable distance with the road surface, described supporting plate 16 is fixing by the carriage pole 19 that is installed on longeron 18; Described ratchet support 24 the place aheads are provided with hinge wheel rotating shaft 25 by the hinge wheel support 28 that is fixed on the longeron 18, described hinge wheel rotating shaft 25 can be rotated around hinge wheel support 28, described hinge wheel rotating shaft 25 is provided with initiatively hinge wheel 26, the end of described hinge wheel rotating shaft 25 is provided with driven hinge wheel 3, be wound with backguy 1 on the described active hinge wheel 26, described backguy one 2 one ends are fixed on the active hinge wheel 26, described backguy one 2 other ends link to each other with the operating handle 1 that is positioned at operator's compartment, on the described driven hinge wheel 3 backguy 2 27 is installed, one end of described backguy 2 27 is installed on the driven hinge wheel 3, and the other end of described backguy 2 27 links to each other with ratchet 4.
When automobile is in a state of emergency need stop immediately the time, start this brake equipment, i.e. pulling is positioned at the operating handle 1 (as Fig. 1 direction of arrow) of automobile cab, under the tension of backguy 1, driving hinge wheel rotating shaft 25 rotates around hinge wheel support 28, thereby drive the driven hinge wheel 3 of hinge wheel rotating shaft 25 ends, driven hinge wheel 3 is rotated backguy 2 27 is packed up, backguy 2 27 pulling ratchets 4 leave ratchet slot 5, thereby remove effect to chain belt wheel 9,9 of chain belt wheels are up time rapidly to rotation under the combined action of moment of torsion that volute spring 1 prestores and chain belt 7 external part gravity, thereby chain belt 7 is transmitted toward automobile back wheel 17 bottoms, after automobile back wheel 17 is pushed down chain belt 7, boss 6 promptly contacts with key shape block 13 on the stepped shaft 10, the effect of drawing of the stone roller of 17 pairs of chain belts 7 of automobile back wheel forces stepped shaft 10 up times to rotation, thereby cause volute spring 2 22 rollings, the kinetic energy of automobile is converted into the elastic potential energy of self, mechanical analysis shows: will force the positive pressure of automobile back wheel 17 road pavement to be strengthened gradually to the moment of couple for the up time of brake equipment body and enhancing gradually by 2 22 effects of rolling volute spring, because the design rolling amount of volute spring 2 22 is very little, therefore it is very short that kinetic energy is converted into the process required time of elastic potential energy, in this process, automobile back wheel 17 relative ground-surface slippages increase gradually, if automobile kinetic energy less than maximum flexibility potential energy then in this process the speed of a motor vehicle can reduce to zero; If automobile kinetic energy is very big, volute spring 2 22 rollings are to limit degree, the speed of a motor vehicle is still non-vanishing, can not extend owing to chain belt 7 this moment again, relative chain belt 7 slides and aggravates thereby the rotation that causes automobile back wheel 17 is obstructed, and chain belt 7 relative ground-surfaces slip aggravations, so under strong friction drag effect, the speed of a motor vehicle reduces to zero rapidly.
The reseting procedure of this brake equipment is: start reversing, the potential energy of volute spring 2 22 storages discharges in the process of reversing, under the effect of its reactive torque, drive chain belt wheel 9 and rotate counterclockwise by stepped shaft 10, key shape block 13, thereby rolling chain belt 7, chain belt 7 rolling effects will force automobile back wheel 17 reversings for the power of automobile back wheel 17, that is the energy that accumulates at glancing impact of volute spring 2 22 discharges and becomes the power of reversing.Detach the below of automobile back wheel 17 when chain belt 7, when promptly not pressed by automobile back wheel 17, can stop reversing, the potential energy that volute spring 2 22 will accumulate this moment is basic all to be discharged, and the free state under being in usually automatically, stepped shaft 10 promptly is in its corresponding position, rotate counterclockwise chain belt wheel 9 to common position with the spanner 8 that resets then, ratchet 4 snaps under the self gravitation effect in the ratchet slot 5 on the boss 6, this process makes volute spring 1 moment of torsion that prestored, so far, this brake equipment returns back to stand-by state.When resetting spanner 8 swivel-chain belt wheels 9, because the effect of volute spring 1, to produce the inverse time to the moment of torsion that rotates to stepped shaft 10, but because the rigidity of volute spring 2 22 is much larger than volute spring 1, so moment of torsion is not enough to overcome the opposing moment of torsion of 2 22 pairs of stepped shaft 10 of volute spring, therefore the rotation of stepped shaft 10 is micro-, within the scope of permission.The utility model can only be used for the braking that emergency brake is a purpose under emergency, do not replace existing brake system of car, and the utility model can be practical separately when the need emergency braking, also can use simultaneously with existing brake system.
The outer end of described volute spring 2 22 and suspension hook 21 junctions are provided with rubber block 20.Play the anti-top effect that compresses by 20 pairs of volute springs 2 22 of rubber block.
Described supporting plate 16 is provided with anti-top cover plate 15.Prevent that by being provided with top cover plate 15 prevents to be positioned at the chain belt porpoising about in the of 7 on the supporting plate 16.
The both sides of described supporting plate 16 are provided with guiding side plate 14.Can protect the chain belt on the supporting plate 16 7 by guiding side plate 14 is set, prevent chain belt porpoising about in the of 7.
Described energy-storing automobile emergency braking apparatus, the upper surface of described key shape block 13 is provided with rubber layer.When this automobile emergency braking device work, boss 6 and key shape block 13 flexible contacts.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of technical solutions of the utility model.
