Description

A kind of automobile flat tire automatic safety

The utility model relates to a kind of automobile automatic safety, and particularly during high vehicle speeds, blowing out suddenly can the automatic guidance direction and the device of autostable braking.

Along with the development of auto-industry and traffic route, traffic accident is also risen thereupon.When running at high speed, motor tire blow-out phenomenon takes place often particularly.Especially prominent quick-fried very easily the causing of front-wheel overturned and the grave accident of personal casualty.When the speed of a motor vehicle surpassed 80 kilometers/hour, because the speed of a motor vehicle is too fast, when the front-wheel blow-out, the driver had little time reaction and in time takes measures.Direction is difficult to control.In the case, must overturn or rush at the accident on the dypass limit of blowing out.

The purpose of the utility model will provide a kind of when the speed of a motor vehicle surpasses 80 kilometers/hour exactly, automobile blow out suddenly automatic guidance direction immediately and the co-insurance device that brakes of autostable immediately.

The purpose of this utility model is achieved in that the automobile flat tire automatic safety of being made up of the multi-functional brake cylinder of two trailing wheels, and it is also by shell; The buffer-braking spring; Drag link; Make hydraulic oil produce the annular piston of pressure during in order to sealing grease chamber, decline; The following pull back spring that annular piston is set back; The compression relief cock of direction automatic locking apparatus; Directional locking; Stoplight stop lamp, siren horn, engine off comprehensive switch; The pull bar conduit; Hydraulic oil; The suction coil; Sucker; The recoil spring of impulsive force, protection parts and reduction strike note when slowing down sucker decline; Pull bar; With the movable digonal link that connects of pull bar; With the movable feeler lever that connects of digonal link; With the triangle interlock sheet that the feeler lever activity connects, there is projection shelves bar on the right; The lower end is formed with the movable digonal link that connects of drag link with triangle interlock sheet left end movable connection of angle, upper end.Triangle interlock sheet and feeler lever are associated with anchor shaft, and can be that rotate in the center of circle with the anchor shaft.

The utility model utilizes hydraulic principle owing to adopted the detection driving device, automatic guidance direction and autostable brake in time.Can restore to the original state automatically behind the tyre rebuilding, in order to repeated use.

5. times pull back springs of 1. shells, 2. buffer-braking spring 3. drag links, 4. annular pistons, 6. compression relief cocks, 7. directional lockings, 8. stoplight stop lamps among the figure, siren horn, multi-functional brake cylinder 10. oil storage cups of 9. liang of trailing wheels of engine off comprehensive switch 11. one-way cocks 12. pull bar conduits 13. hydraulic oil 14. shells 15. suction coils 16. recoil springs 17. pull bars 18. conduits 19. suckers 20. digonal links 21. feeler levers 22. triangles interlock sheet 23. digonal links 24. tires 25, it is that 32. reaction plates, 33. intermediate rods, 34. bearings, 35. pull back springs are covered in 31. swings of 30. brake shoe brake cheek that 29. brakings of the 26. grades of bars in ground, 27. anchor shafts, 28. high pressure fuel pipes divide

Among Fig. 1: suction coil 15 is subjected to the control of average speed indicator control circuit, when the speed of a motor vehicle is lower than 80 kilometers/hour, suction coil 15 does not have electric current to flow through, sucker 19 is not produced pulling function, sucker 19 is under the effect of slow medi-spring 16, be in lower end position, feeler lever 21 is horizontal, following pull back spring 5 makes annular piston 4 be in the normal position with

brake recoil spring

2,13 pairs of compression relief cocks 6 of hydraulic oil, directional locking 7, stoplight stop lamp, siren horn, engine off comprehensive switch 8, the multi-functional brake cylinder 9 of two trailing wheels does not produce pressure, owing to be provided with one-way cock 11 between oil storage cup 10 and the oil pocket, in oil storage cup 10, can in time in oil pocket, replenish fluid.Shell 1 top has pore, when descent of piston, in case top produces negative pressure.

Among Fig. 2: when the speed of a motor vehicle is higher than 80 kilometers/hour, under the effect of average speed indicator control circuit, suction coil 15 is connected with electrofiltration, sucker 19 is picked up, pull bar 17 with on move, digonal link 20 is also upwards stretching thereupon, feeler lever 21 is in state perpendicular to the ground, its lower end and road surface keep certain distance, are in detected state.

Among Fig. 3: when the speed of a motor vehicle is higher than 80 kilometers/hour, two front-wheels are which blow-out no matter, and the whereabouts that follows hard on car body forces feeler lever 21 rapid kiss the earths with the strength of advancing, and is that center of circle anticlockwise direction turns an angle to the back upper place with anchor shaft 27.Shelves bar 26 on the feeler lever 21 diabolos interlock sheet 22 produces an application force, triangle interlock sheet 22 is that the garden heart rotates counterclockwise with anchor shaft 27, it is drop-down that digonal link 23 drives drag link 3, recoil spring 2 presses down and acts on annular piston 4-downforce simultaneously, hydraulic oil 13 is produced pressure, utilize hydraulic principle, directional locking 7 is fixed on direction on the former travel direction immediately, in case direction out of control and partially running, comprehensive switch 8 is in time opened stoplight stop lamp simultaneously, the siren horn and the firing circuit that kills engine, the multi-functional brake cylinder 9 of two trailing wheels in time brakes, because the effect of buffer-braking spring 2, and the undue emergency braking when having avoided running at high speed, to guarantee the safety of occupant or goods and materials.Respond at navigating mate, and take the related emergency measure.After the speed of a motor vehicle was reduced to certain speed of a motor vehicle, direction control compression relief cock 6 was opened pressure release automatically, was disengaged with reaching directional locking 7 functions.This device can be installed on the automobile front axle, and the distance between feeler lever 21 and the road surface does not change with the auto body up-down vibration like this, and it is retractable that control stalk 21 can be made length, can regulate the length of feeler lever 21 by the tire size.

Fig. 4 is a kind of structural representation of directional locking 7.Directional locking is equipped with 30 two of tooth shape brake shoe brake cheek by reaction plate 32 on the reaction plate 32, brake cylinder 29, and pull back spring 35, bearing 34, what match with reaction plate 32 also can be along with the swing lid 31 that tierod 33 is slidingly connected is formed.Hydraulic oil is pressed oil by the brake cylinders in the directional locking 7 of high pressure fuel pipe 28 29 during back tire patching, checks the swing lid 31 of the sway with tierod 33, thereby reaches controlling party to the purpose of not running partially.
