Abstract

The invention discloses an emergent braking device of a four-wheel electric vehicle. The emergent braking device is an automatic device which can be immediately braked when the front end of the vehicle encounters an obstacle. The method is that the front end of the carriage is provided with a plurality of sensitive triggers which drive a switch, when the front end of the carriage encounters the obstacle, the switch immediately cuts off the power supply of a driving motor. The driving motor is provided with a device of disconnecting-automatic internal contracting brake, when the power supply is cut off, the motor is immediately stopped so that the vehicle can be quickly stopped.

Description

Self-propelled vehicle electric braking device

Technical field

Patent self-propelled vehicle electric braking device of the present invention, relates to a kind of driving safety device of self-propelled vehicle.

Background technology

Still at the self-propelled vehicle of a large amount of internal combustion engine types that use, because the principle of its design is limit, in the time that front runs into dangerous situation, cannot allow self-propelled vehicle slow down as early as possible, stop at present, the miserable traffic accident that therefore for this reason led to over more than hundred year, just countless.Analyzing the reason that these accidents occurred in the past, after all, is the design engineers because of " modern age " self-propelled vehicle, does not grasp well the limitation of classical mechanics field of application! Because vehicle, in the time running at high speed, because kinetic energy stored on wheel is too large, is depended merely on mechanical braking, be not enough to allow at short notice the rotating speed of wheel subtract.

Before more than hundred year, the forerunner of automobile industry, invention and produce the vehicle of the four wheels taking combustion engine as power, it can replace the vehicle of horse traction, on road surface, quickly runs, and this has been a very marvelous invention; Because the speed of a motor vehicle is at that time not high, so by traditional mechanical braking mode, a kind of simple, economic and failure-free scheme of can yet be regarded as.

But due to the needs of society development in modern age, impel that self-propelled vehicle is manufacturing to be developed rapidly, the speed of a motor vehicle originally, can not satisfy social needs far away, just road speed is brought up to several times in the past, and " quantitative change " caused " qualitative change ".But the design engineers of self-propelled vehicle industry, the requirement of but not keeping pace with the times, still stick to that a set of established practice of ancestor, " safety " driving, great like this problem for how, they did not carry out in depth studying and taking corresponding behave, cause meaningless traffic accident again and again to occur, even buried many ghosts of the wronged! This has to say modern self-propelled vehicle industries, how the debts of blood that the mankind are owed!

Summary of the invention

Nowadays, man invented has gone out electrical motor, and finds that its function is easy to " transposition ", and (" turning " use around) just become electrical generator.Utilize this special performance, it is upper that people can be used in it " braking " easily,, in the wheel of self-propelled vehicle, a motor is installed.(in fact, the mankind have used already on trackless and tramway train, and only the design master's homegate " ignorant and ill-informed " of internal combustion engine motor vehicle, is slow at " reference "! )

Now aim at this preceence of discussing " electric braking " and its range of use.

Motor, in the time using as electrical generator, is characterized in, rotating speed is faster, and the energy of its output is also just larger, that is to say, " merit " that it is exported is also just larger.Therefore, when vehicle is in while running at high speed, because of its " kinetic energy " " being full of " very large, imagination, if now the load of the motor on wheel is strengthened, (for example, by its mouth short circuit), just can consume soon the kinetic energy that travels of self-propelled vehicle, makes it subtract soon lower speed.

The present invention, negates not thoroughly effect of mechanical braking, because, after the moving velocity of car has dropped to a certain degree, to brake by motor, its effect will lower greatly, thereby when low speed, still will rely on traditional mechanical system to brake.

Claims

1. patent self-propelled vehicle electric braking device of the present invention, is characterized in that in the time that vehicle runs into dangerous situation and needs emergency brake, relies on the motor C in wheel nave B to do electric braking.

2. according to claim 1, in the wheel hub of wheel, motor C is housed.
