Abstract

The invention discloses a device for preventing brake failure of an automobile. In the device, both left and right sides of the automobile, close to the back part of the automobile body, are symmetrically provided with a hydraulic telescopic support leg which is inclined backward and downward; the lower end parts of the support legs are provided with anti-skid wheels which are compound entity tires formed by steel wire wheels formed by radial bundled steel wires arranged on hubs, and rubber rings arranged between the bundled steel wires, wherein the top ends of the bundled steel wires are no lower than the surfaces of the rubber rings; and the device also comprises a controller which can control the hydraulic telescopic support legs to be extended downward so as to make the anti-skid wheels touch the ground when the automobile is braked on a wet and slippery road and control the hydraulic telescopic support legs to be retracted and not to participate in the braking action when the automobile runs on a normal road. The device of the invention can generate a friction torque coupling balancing a braking torque coupling causing side skidding and uncontrollability due to weather and road conditions when the automobile is braked, thereby avoiding the side skidding, turning-over and chain collision when the automobiles are braked on a wet and slippery road.

Description

Anti-braking device out of control of self-propelled vehicle and anti sliding wheel

Technical field

The present invention relates to the anti-braking of a kind of self-propelled vehicle device out of control; Be a kind of brake equipment specifically; Can not diminish because of the ground friction coefficient (being reduced to about 0.1) by about 0.6 out of control; This device can produce enough square idols, resists the square idol that brake produces, to guarantee the not out of control and personal safety of vehicle.

Background technology

Theoretical according to traditional mechanics, the power in the one-dimensional space, single power can not balance.Necessary another one power just might balance.Equilibrium conditions is: the equilibrium conditions of balance between two forces is: equal and opposite in direction, in the opposite direction acts on (rigid body) on the same straight line, or acts on (deformable body) on the collinear same point.

The moment of couple in the two-dimensional space: with equilibrium of forces, in one step of amplification, if two power of balance do not act on the same straight line, and at a distance of being d, it is plain just to have produced a new power this moment: moment of couple M=Fd; Though this moment of couple comprises two power, because of not acting on the same straight line, so it is plain to become a new two-dimentional power.The moment of couple and power can not replace mutually, are that the power of two-dimensional space is plain.Moment of couple can not balance, and it rotates object, balance that the another one moment of couple must be arranged; EQUILIBRIUM CONDITION is: numerical values recited equates; In the opposite direction, effect (rigid body) at grade, or act on (deformable body) on the conplane same point.

With the balance of the two-dimentional moment of couple, amplify one again and go on foot three dimensional space, if two moments of couple do not act on the same plane A, the another one moment of couple act on plane A on the B face of d.Cause two moments can not equate that not at grade it is plain therefore to have produced a new power again at three dimensional space---square idol (at three dimensional space).Traditional in the past rigid dynamics does not have clear and definite call, just in strength of material, is called moment of torsion.And think that initiatively moment is arranged, and must binding square, they are with regard to balance.The square idol of at present having a talk and traditional mechanics are in notional difference:

(1) square is the new power element that is formed by two moments of couple by chance.Single square be by chance can not balance (producing motion or geometry deformation), must have an other square by chance could with its balance.

(2) square is the power element in the three dimensional space by chance, necessary another square idol of balance.Equilibrium conditions is: numerical values recited equates (because the moment of couple and square idol all are algebraic quantities, having only positive and negative), and the numerical value equal symbol is opposite, acts in the same three dimensional space and gets final product balance.

(3) square is exactly that the power of three dimensional space outwardness is plain by chance, and its action effect changes object moving state---rotate its geometric shape warpage that rotates during statics around square idol effect axle.

Self-propelled vehicle is to utilize wheel and ground-surface friction force to produce " gradeability " so that the speed of a motor vehicle reduces when brake.This moment should be to forward roll, but the stabilizing couple square that the gravity of vehicle returns after two front-wheels are produced.Still have the danger of rollover this moment, but gravity also plays stabilization to the wheel of both sides, and remaining is exactly the rotation around vertical pivot, has just produced out of control at this moment.Because of wet and slippery surface friction coefficient especially little (have only about 0.1, can not produce the active square idol that enough square idol is come the balance brake), therefore can cause out of controlly at glancing impact, therefore tragedy produces.

Summary of the invention

To current mobility car brake problem out of control, the object of the present invention is to provide the anti-braking of a kind of brand new self-propelled vehicle device out of control.

The present invention adopts following technical solution: the anti-braking of a kind of self-propelled vehicle device out of control; Be to install one to oblique back lower place bevelled hydraulically extensible supporting leg near the left and right sides symmetry of body tail at self-propelled vehicle; Anti sliding wheel is installed in the supporting leg bottom; Said anti sliding wheel is to constitute compound tire by wire wheel and the rubber ring between the bundled steel wires that the steel radial bundle that is installed on the wheel hub forms, and the bundled steel wires top is not less than the rubber ring surface; Also comprise controller with on wet and slippery road surface during brake control hydraulically extensible supporting leg stretch out downwards anti sliding wheel landed, and when normal condition of road surface went, it was collapsed state that controller is controlled described hydraulically extensible supporting leg.

The present invention also provides a kind of anti sliding wheel, is to constitute compound tire by wire wheel and the rubber ring between the bundled steel wires that the steel radial bundle that is installed on the wheel hub forms, and the bundled steel wires top is not less than the rubber ring surface.

The anti-braking of this self-propelled vehicle of the present invention device out of control; When self-propelled vehicle brakes on the smaller wet and slippery road surface of friction coefficient, adopt the anti sliding wheel of holding to the telescopic outrigger portion of the back lower place to land, because anti sliding wheel adopts the steel radial bundle; The bundled steel wires top contacts with the road surface; Itself and ground-surface friction coefficient are much larger than conventional tyre and ground-surface friction coefficient, so its square idol and skid square even balance, reach the effect of the cross-up system of preventing.The invention provides motor-driven braking scheme of a kind of brand new, it is out of control effectively to avoid braking, and has avoided causing serious accidents such as shunting into one another, overturn, roll away from road after out of control.
