Abstract
The invention provides an automobile braking distance shortening device which can make the contact area between an automobile tire in an emergency braking state and the ground be increased through automatic deflation so as to achieve the purpose of shortening the braking distance. According to the automobile braking distance shortening device, on an automobile with an ABS, an ABS electronic control unit is used for making a triggered time-delay relay operate and finally making an electropneumatic valve installed inside a hub operate; on an automobile without the ABS, an electric contact pressure gauge installed on an automobile braking tube is used for making the triggered time-delay relay operate and finally making the electropneumatic valve operate. The triggered time-delay relay turns off a circuit at a set time, then, the electropneumatic valve stops operating, and tire pressure right drops to set minimum pressure at this time.
Description
Technical field
The present invention is a kind of shortening braking automobile distance means, can realize automobile and shorten braking distance in emergency braking situation.
Background technology
In prior art, automobile ABS anti-lock braking system is now very common.ABS anti-lock braking system can make the wheel can locking in the situation that resolutely touching on the brake pedal, reaches the maximum frictional force of tire.On ABS anti-lock braking system basis, can also shorten the also not invention of device of braking distance.
Summary of the invention
The object of the invention is to make automobile to shorten braking distance in emergency braking situation, thereby improve the safety performance of automobile.
According to technical scheme provided by the invention, mechanism comprises: trigger type time-delay relay, electromagnetic gas valve, electromagnetic switch, wire loop.ABS electronic control package is connected with trigger type time-delay relay by the first wire, trigger type time-delay relay is connected with electromagnetic switch by the second wire, trigger type time-delay relay is connected with automobile power source by privates, wire loop is connected with electromagnetic gas valve by privates, wire loop is fixed on wheel hub, corresponding with electromagnetic switch.If there is no the vehicle of ABS anti-lock braking system, on brake line, add electro connecting pressure gauge, electro connecting pressure gauge replaces the above-mentioned position of ABS electronic control package, by the 5th wire, is connected with automobile power source.
Automobile ABS anti-lock braking system is very little work in general brake situation, only has and runs into emergency situation when chaufeur, resolutely touches on the brake, and when tire is wanted locking, just works.Braking automobile distance determined by tire and ground maximum static friction force, the same environmental conditions Automobile Maximum static friction force of making decision: the area of contact on the friction coefficient between automotive dead weight, ground and tire, tire and ground.It is impossible that friction coefficient under same environmental conditions between automotive dead weight, ground and tire is want to change in moment, only has the area of contact that increases ground and tire could shorten braking distance.The area of contact of wanting to increase ground and tire only has by reducing tire pressure increases area of contact.Most of automotive tire pressure is generally 2.5kg/cm2, the minimum 1kg/cm2 left and right of generally can arriving of tire pressure, and when tire pressure arrives 1kg/cm2 left and right, the area of contact on tire and ground can increase much, and concrete every kind of tire of pressure minimum is slightly different.
The present invention is simple in structure, science, feasible; Can shorten the braking distance of automobile in emergency braking situation.

Not with the vehicle of ABS anti-lock braking system, electro connecting pressure gauge 9 is installed on brake line to be connected with automobile power source 12 by the 5th wire 10, by the first wire 5, be connected with one of them terminals of control circuit of trigger type time-delay relay 1, another terminals ground connection of trigger type time-delay relay 1 control circuit, trigger type time-delay relay 1 is having output circuit conducting under the state of trigger current, one of them terminals of the output circuit of trigger type time-delay relay 1 are connected with automobile power source 12 by privates 7, another terminals are connected with electromagnetic switch 3 by the second wire 6.Electromagnetic switch 3 is arranged on brake callipers 13, negative earth, and electromagnetic switch 3 has the telescopic head of electromagnetic control, is graphite, connects the second wire 6.Wire loop 4 tape insulation foundation rings and privates 8, wire loop 4 is fixed on the outside inner side by brake callipers 13 of wheel hub 14, and electromagnetic switch 3 is corresponding, with wheel hub 14 insulation, wire loop 4 with privates 8 through wheel hub 14, enter wheel hub 14 inner chambers, insulate and carry out sealing with wheel hub 14.Wheel hub 14 has hole, and electromagnetic gas valve 2 is arranged on wheel hub 14 inner chambers, and air extractor duct, in perforate, is carried out sealing, and electromagnetic gas valve 2 negative poles are just connected on wheel hub 14, equal ground connection, and the anodal privates 13 that pass through are connected with wire loop 4.
Principle of work of the present invention and working process:
In Fig. 1 example illustrated, when at automobile emergency brake in the situation that, ABS electronic control package 11 is started working, electric current is transferred to the control circuit of trigger type time-delay relay 1 by the first wire 5, trigger type time-delay relay 1 is connected output circuit at once, electric current is just transferred to electromagnetic switch 3 by privates 7, just work of electromagnetic switch 3, graphite head is charged and stretch out, graphite head touches wire loop 4, electric current is sent to electromagnetic gas valve 2 by privates 8, electromagnetic gas valve 2 is worked immediately, open air valve, the gas of wheel tyre cavity is discharged fast, tire pressure declines at once, it is large that the area of contact on tire and ground becomes, friction force increases, thereby shortening braking distance.The venting opening diameter of electric control valve 7 is in 20 millimeter, and venting speed is very fast, through test, in 0.5 to 1 second, can make tire pressure drop to 1kg/cm2 from 2.5kg/cm2.Trigger type time-delay relay 1 has clock mechanism, can set the time of outgoing current, time is set in 0.5 to 1 second, no matter how long the trigger current of ABS electronic control package 11 continues, trigger type time-delay relay 1 always set time separated, when trigger type time-delay relay 1 circuit disconnects, electromagnetic gas valve 2 is closed immediately, stop venting, at this moment tire pressure just in time can drop to 1kg/cm 2 left and right.If encounter again emergency situation brake at once, because trigger type time-delay relay 1 wants to work on, must click reset key, so at this moment even ABS electronic control package 11 has trigger current, trigger type time-delay relay 1 can not worked yet, and wait chaufeur to click reset key and just can work on.
In Fig. 2 example illustrated, when at automobile emergency brake in the situation that, natural reaction due to chaufeur, brake pedal can be stepped on suddenly, pressure when at this moment the pressure in brake line can brake is than usual large, can reach the pressure connection value that electro connecting pressure gauge 9 is set, electro connecting pressure gauge 9 can be connected circuit, electric current is transferred to the control circuit of trigger type time-delay relay 1 by the first wire 5, trigger type time-delay relay 1 is connected output circuit at once, electric current is just transferred to electromagnetic switch 3 by the second wire 6, just work of electromagnetic switch 3, graphite head is charged and stretch out, graphite head touches wire loop 4, electric current is sent to electromagnetic gas valve 2 by privates 8, electromagnetic gas valve 2 is worked immediately, open air valve venting, it is separated when trigger type time-delay relay 1 circuit is being set, electromagnetic gas valve 2 is closed immediately, stop venting, at this moment tire pressure just in time can drop to 1kg/cm 2 left and right.If encounter again emergency situation brake at once, because trigger type time-delay relay 1 wants to work on, must click reset key, so even at this moment electro connecting pressure gauge 9 has trigger current, trigger type time-delay relay 1 can not worked yet, and wait chaufeur to click reset key and just can work on.
