Full distance, prevent braking vane from influenceing the normally travel of automobile, running into the original brake system failure of automobile and needing urgent stop
During the special circumstances of car, driver can control spacer pin to move by control device, so as to release spacer pin to connecting rod
The restriction of position, so as to discharge braking vane, now braking vane can be met to tire working face under gravity, once there is friction,
Self-locking will be triggered, frictional force is bigger, and pressure is bigger, and pressure is bigger, and frictional force is bigger, forms positive feedback, and final braking vane will be
Enough frictional force is produced in very short time to tire, so as to emergency brake, plays the effect for making up former car brake failure.
Preferably, the rotating shaft is provided with torsionspring with connecting rod hinged place, then when spacer pin discharges braking vane, stops
Sweep will meet working face to tire in the presence of the dual pulling force of the moment of torsion of self gravitation and torsionspring, to increase brake
For plate to the pressure of tire, the situation on tire working surface can not be pressed onto by preventing the braking vane caused by vehicle deceleration.
Preferably, the control device includes being arranged on handle in driver's cabin, the handle by drag-line with it is described spacing
Pin connection.
Preferably, the spacer pin is slidably connected with car body, and the spacer pin can be stretched in the presence of the handle and drag-line
Go out or retract, to realize fixation or release to connecting rod.
Preferably, diaphragm is provided with the working face that the braking vane is used to contact with wheel, to prevent braking vane
Working face is got rid of by wheel to be splashed silt and causes dynamic friction factor to reduce, using this design, even if there is silt, and the tire in brake
Caused huge frictional force can also quickly scrape off diaphragm so as to expose working face between braking vane.
Preferably, the diaphragm is plastic foil.

Embodiment
The embodiment of technical solutions of the utility model is described in detail below in conjunction with accompanying drawing.Following examples are only
For clearly illustrating the technical solution of the utility model, therefore example is only used as, and this practicality can not be limited with this
New protection domain.
As Figure 1-4, a kind of emergency brake arrangement that the embodiment of the utility model one provides, including rotating shaft 1, connecting rod
2nd, spacer pin 3 and braking vane 4, one end of the rotating shaft 1 are fixedly connected in car body (not shown), the other end and the company
One end of extension bar 2 is hinged, and the other end of connecting rod 2 is fixedly connected with the braking vane 4；The spacer pin 3 slides with car body 7 to be connected
Connect, the spacer pin 3 is connected by drag-line 5 with the handle 6 being arranged in driver's cabin.Generally, in the effect of spacer pin 3
Under so that braking vane 4 keeps certain safe distance with tire 8, prevents braking vane 4 from influenceing the normally travel of automobile, is running into
The original brake system failure of automobile and when needing the special circumstances of emergency brake, driver can be with rotational handle 6, by spacer pin
3 pull out, and at this moment braking vane 4 and connecting rod 2 can meet the working face to tire 8 under gravity, once there is friction, will trigger certainly
Lock, frictional force is bigger, and pressure is bigger, and pressure is bigger, and frictional force is bigger, forms positive feedback, final braking vane 4 will be in very short time
It is interior that enough frictional force is produced to tire 8, so as to emergency brake, play the effect for making up former car brake failure.
Further, above-mentioned rotating shaft 1 and the hinged place of connecting rod 2 are provided with torsionspring (not shown), then work as limit
Position pin 3 discharge braking vane 4 when, braking vane 4 will be met in the presence of the dual pulling force of the moment of torsion of self gravitation and torsionspring to
The working face of tire 8, to increase pressure of the braking vane 4 to tire 8, prevent caused by vehicle deceleration that braking vane 4 can not
It is pressed onto the situation of the working surface of tire 8.
Further, on the working face for being used to contact with tire 8 in above-mentioned braking vane 4 plastic foil is provided with (in figure not show
Go out), cause dynamic friction factor to reduce to prevent from the working face of braking vane 4 from being got rid of by tire 8 splashing silt, using this design, i.e.,
Make have silt, brake when tire 8 and braking vane 4 between caused huge frictional force can also quickly scrape off plastic foil from
And expose the working face of braking vane 4, the emergency brake effect of braking vane 4 is not influenceed.
As shown in figure 5, it is the force analysis figure under the working condition of braking vane 4, due to rubbing between braking vane 4 and tire 8
Power is wiped much larger than the gravity of itself of braking vane 4, therefore, in force analysis, the gravity of braking vane 4 is have ignored, is calculated with simplifying；
In Fig. 5, frictional force of the f between braking vane 4 and tire 8, T be connecting rod 2 to pulling force caused by braking vane 4, F is connecting rod 2
Component of the pulling force T along the length direction of braking vane 4, N be tire 8 to holding power caused by braking vane 4, α is connecting rod 2 and brake
Angle between plate 4, r is height of the rotating shaft 1 apart from the center of circle of tire 8, if the radius of tire 8 is R, between braking vane 4 and tire 8
The coefficient of kinetic friction be μ, then when braking vane 4 works, as long as meeting f>F, you can tightly embrace tire 8 and produce brake weight, by
Force analysis is understood：
F=Tcos α,
F=μ N=μ Tsin α；
When i.e. braking vane 4 produces the brake weight for holding tire 8 tightly, need to meet：
μ>Ctg α=r/R；
Now, be not required to impressed pressure can locking tire 8 realize brake, this state is properly termed as self-locking state；From
The braking vane 4 of different surfaces material, you can change coefficient of kinetic friction μ, then calculate rotating shaft 1 by above formula justifies apart from tire 8
The height r of the heart.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：
It can still modify to the technical scheme described in previous embodiment, either to which part or all technical characteristic
Carry out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from the utility model embodiment
The scope of technical scheme, it all should cover among claim of the present utility model and the scope of specification.
