Abstract

The invention discloses an automobile braking device for mountain roads. In the device, the traditional friction braking is changed into compressed air damping braking, so the troubles of cooling with water and requiring frequent change of brake leather are eliminated, and the compressed air counteracts on the air compressor to provide certain power for an automobile. In the invention, waste is changed into valuable materials.

Description

A kind of brake device for car that is applicable to the hill path

Technical field

The brake component that the present invention relates to use on the automobile specifically is exactly a kind of brake device for car that is applicable to the hill path.

Background technology

Automobile brake, it is more and more advanced to be accompanied by developing of automobile industry.But, although evolve to hydraulic pressure from rope, evolve to again electronic, still do not break away from two kinds of disc type and drum-types existing in the mode of friction force as braking force.

Our country has a lot of automobiles to travel in high mountain Chong Ling throughout the year, and the gradient of highway not only greatly but also very long.So throughout the year the automobile at mountain driving all will have a water tank, the clear water that is used to cool off is filled in the inside, everyly will use the water cooling brake hubs down-hill the time always, otherwise will have an accident because of brake hubs.Even also to repair the pond that is specifically designed to cooling on the way, automobile will often cool off brake hubs in the pond.Not only influenced the speed of driving, and the brake leather to often be changed also.

So, traditional brake mode can be changed, the period of service of brake leather can be prolonged, guarantee traffic safety again? is does even the kinetic energy that produces can also be descending the time change into kinetic energy and used?

The present invention is exactly a kind of trial of attempting to break through the traditional braking mode.

Summary of the invention

We know, wheel can automatic rolling under the effect of deadweight during automobile downhill, the present invention utilizes this kinetic energy of automobile to drive (certainly preferably many) air compressor (this Air compressor both can be in the form of piston also can be rhodes blower and so on), air compressor produces pressurized air during descending under the drive of wheel, the shock damping action that this pressurized air produces can slow down the speed of wheel rotation, simultaneously pressurized air is saved in the air tank.Inference if the dumping force that pressurized air produces is enough big, will stop wheel revolutions as can be known certainly.When going up a slope by the time, again the pressurized air in the air tank is directed in the Air compressor, has promoted wheel revolutions so can assist again.

Embodiment

If autotruck can be considered several small-sized air compressors of installing more, each all is associated with wheel respectively; If miniature car just can consider that few installation is several, and can directly be associated with power take-off shaft.

From scheme drawing 1 as can be seen, when automobile goes up a slope, bi-directional electromagnetic valve coil 6-2 and 11-1 action, the piston in the electromagnetic valve 6 is in 7 position, and the piston in the bidirectional electromagnetic valve 11 then is in 9 position.At this moment, the pressurized air in the air tank just can enter Air compressor, thereby promotes blade or piston motion in the Air compressor, and the air of finishing merit directly is discharged in the atmosphere, and the result of this motion is exactly the propelling vehicle wheel turns.Even if can not produce much power, can eliminate the kinetic energy that the Air compressor running will consume at least.That is to say that automobile has been installed after the present invention, can't increase extra consumption of power.Certainly, also such situation might occur: automobile will produce negative pressure also at half way up the mountain and the pressurized air in the air tank has almost been used up if continue to allow air tank be connected with Air compressor again, and that just will consume a large amount of power.So, we have installed pressure detector 14 on air tank, when the air pressure in micro computer detects air tank drops to certain degree, just send instruction, order bi-directional electromagnetic valve coil 6-1 action, drive piston and run to 5 position, thereby the porting of Air compressor is all directly communicated with atmosphere, reduce consumption of power to greatest extent.

When automobile when horizontal road is travelled, chaufeur utilizes the coast of automobile sometimes, and this time, chaufeur was just regained throttle, did not depress brake pedal.In this time, micro computer detects the throttle withdrawal will send designated command bi-directional electromagnetic valve coil 6-1 action, and (even if run to 5 position, also it doesn't matter to send out once command again for the state of drive piston motion to 5.There is no need in the control program of micro computer, to be detected); Order bi-directional electromagnetic valve coil 11-1 action to drive piston simultaneously and run to 9 state.From scheme drawing as can be seen, at this moment the admission port of Air compressor and air extractor duct all communicate with atmosphere, so just minimum degree are reduced in the consumption of power of Air compressor.

When automobile began descending, chaufeur not only will be regained throttle, also will suitably depress brake pedal.After micro computer detects brake pedal and depresses, will order bidirectional electromagnetic valve 11-2 action to drive piston and run to 10 position, at this moment, Air compressor promptly begins pressurized air.Certainly, if automobile has been used up the pressurized air in the air tank when going up a slope, the air resistance that Air compressor work produces during descending is very little at the beginning, for the needs that guarantee to brake, can pressure valve be set in the position of signal Figure 13.

Need to prove that accompanying drawing 1 given scheme drawing of the present invention only is a kind of pri structure, is not the pressurized air damping brake on the absolute sense, says to be a kind of mode of auxiliary braking effectively exactly.Because if will adopt the pressurized air damping brake utterly, will carry out step-less adjustment to the delivery pressure of Air compressor, and this point can realize fully under current engineering factor, Here it is in accompanying drawing 3 given embodiment.As can be seen from the figure, the maximum of both (Fig. 1 and Fig. 3) difference just is: the air inlet/outlet of Air compressor has increased a stepping motor or servomotor again respectively among Fig. 3 except bidirectional electromagnetic valve is installed.This motor is under the control of micro computer, can synchronous working with Das Gaspedal, brake pedal, that is to say, when chaufeur depresses brake pedal, the just direct and atmosphere connection admission port of the bidirectional electromagnetic valve of Air compressor inlet, outlet is closed the interface channel of exhausr port and atmosphere simultaneously.Simultaneously, motor 2-13 cut-out air tank is connected with the air compressor air intake mouth, motor 2-10 then according to brake pedal stroke synchro control position of piston---the stroke of pedal is big more, the degree that the Air compressor air extractor duct stops up is just big more, the dumping force that pressurized air produces is also just big more.In like manner, during upward slope when chaufeur depresses Das Gaspedal, the bidirectional electromagnetic valve 2-4 control plunger of admission port cuts off the passage of admission port and atmosphere, and the bidirectional electromagnetic valve 2-7 of air extractor duct opens being connected of Air compressor and atmosphere, and motor 2-10 cut-out Air compressor is connected with air tank.Simultaneously, motor 2-13 is according to the stroke of the stroke of throttle decision piston,---the throttle stroke is big more, and the interface channel of Air compressor and air tank is big more, and this just feasible air supply that enters Air compressor is directly proportional with the size of throttle.Certainly this is more satisfactory controlling schemes.

Be stressed that at last, this specification sheets for embodiment be the special case of one or two kind of fairly simple reality, do not have, can not exhaustive various embodiments yet.Any technical method of deriving on this basis all belongs to protection domain of the present invention.
