Embodiment
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it will be appreciated that described herein excellent
Select embodiment to be only used for describing and explaining the present invention, be not used to limit the utility model.
Embodiment：As shown in Figs. 1-3, a kind of end executive device of Vehicular intelligent composite braking of the utility model, including
End braking device 2, end braking device 2 are fixedly installed on the vehicle high-speed axis 11 of 1 one end of vehicle tyre connection, end system
Dynamic device 2 includes is equipped with pneumatic cylinder 3, air spring 4, pressurized seal plate 5, braking in exterior housing 10, housing 10
Friction plate 6, braking metal dish 7, permanent-magnet 8 and coil 9, are braked on some projection small columns of 7 side of metal dish around wired
Circle 9, the outside of coil 9 are equipped with permanent-magnet 8, and 11 one end of vehicle high-speed axis is braked metal dish 7 and passed through through braking metal dish 7
Vehicle high-speed axis 11 is connected with brake strip 6, and close installation has pressurized seal plate 5 at 6 side end face of brake strip, and air pressure is close
5 side of sealing plate is connected by air spring 4 with pneumatic cylinder 3, and 11 one end of vehicle high-speed axis is extended to outside housing 10 through pneumatic cylinder 3
Portion.Pneumatic cylinder 3 is equipped with four air inlets, and pneumatic cylinder 3 is connected by air inlet with exterior air pump, and vehicle tyre 1 is equipped with four
It is a, and end braking device 2 is mounted at each 1 inner side of vehicle tyre, stayed between brake strip 6 and braking metal dish 7
Have the gap, 4 section of air spring is different two concentric circles of radius size, and gas is pressed into through air flue after entering in cylinder and inflates
It is allowed to stretch to realize external acting toward both sides between the inside and outside side form of spring 4.Protected between the internal membrane and axle of air spring 4
Hold the damage that a certain distance is brought to avoid friction.The side of air spring 4 is opposite with the side of pneumatic cylinder 3 to be connected to realize
The transmission of gas, opposite side carries out sealing by pressurized seal plate 5 prevents gas leakage.After gas is filled with, gas connects air spring 4
The side for having pressurized seal plate 5 jacks up, and air spring 4 recovers elastic deformation so as to which pressurized seal plate 5 be retracted automatically after deflation,
The generally cylindrical shape of pneumatic cylinder 3, and be attached between pneumatic cylinder 3 and vehicle high-speed axis 11 using deep groove ball bearing.
Specifically, in use, the priority of electromagnetic braking is braked more than conventional gas under normal circumstances.When vehicle is just
Often during traveling when needing to be braked, driver, which sends signal, makes the device enter working status, at this time external device (ED) and
The contactor closure that coil 9 forms forms path, the cutting magnetic induction line in the magnetic field that permanent-magnet 8 produces, one side coil 9
In can produce that sensing electric current outflow is collected through foreign current and reforming unit etc. carries out recycling, one side coil 9 can be by
To the inhibition of Ampere force, so that vehicle is subject to resistance and produces the effect of braking.If vehicle need not carry out at this time
Brake, then only need to control its circuit so that the closed circuit being made of coil 9 etc. disconnects, coil 9 cannot be formed and closed
Closing circuit would not be acted on be subject to Ampere force, so that the effect of braking will disappear.
Two stage braking is air-pressure brake in this brake apparatus, if after the air-pressure brake pattern of device starts, by vehicle-mounted computer
Send pump-up device fast aeration into pneumatic cylinder 3 outside signal command, four holes of pneumatic cylinder 3 outside that is independently connected is inflated
Device.Gas is pressed into through pneumatic cylinder 3 between the two membranes of air spring 4, and the right side of air spring 4 is forced laterally stretch
Exhibition, pushes directly on pressurized seal plate 5 and moves to the right, since pressurized seal plate 5 and brake strip 6 are rigidly connected, system
Movable friction plate 6 is promoted indirectly slowly presses to braking metal dish 7.When gas is enough, brake strip 6 and braking metal dish 7
It is in contact and carries out friction catch to make vehicle braking deceleration.If the signal that driver sends is than stronger, controllable air inlet situation
To increase the transverse pressure of brake strip 6, friction brake torque bigger can so be made by being obtained according to physical friction formula, braking
Effect is more preferable.
If driver sends brake signal in normal brake application, electromagnetic braking is carried out first according to priority, when vehicle speed
When degree is declined to a certain extent, the effect of electromagnetic braking and energy regenerating has died down, and device control at this time carries out two level gas
Friction catch is pressed, after friction catch is carried out for a period of time, electromagnetic braking failure, vehicle system is individually carried out by air pressure friction catch
Move until vehicle stops completely.That is, it is contemplated that the complexity of road conditions, the device can carry out an automobile's instant velocity and sentence
Disconnected, when vehicle is being braked and speed declines to a certain extent, air pressure friction catch starts startup and comes into force, when vehicle is instantaneous
Speed exceedes setting value when speed is very big in other words, has level-one electromagnetic braking to carry out single work deceleration, this is under normal circumstances
Braking.
If driver needs to carry out emergency braking, the signal of emergency braking is sent by driver, then the device cancels system
Dynamic priority, electromagnetic braking and friction catch are carried out at the same time work, and at the same time the braking effect of friction catch can be according to driving
Signal strength that the person of sailing sends is adjusted, to ensure the intensity of braking.When vehicle speed declines to a certain extent, by outer
Portion's electric power system inputs certain electric current to carry out electromagnetism auxiliary braking to coil 9, can be in setting range according to driver
The power of signal carrys out the size of control input electric current, and the bigger Ampere force of electric current is bigger and then the brake drag of acquisition is bigger, auxiliary
Braking effect is more obvious, last untill driver cancels brake command.
The device carries out automatic grading probes brake measure, and electromagnetic braking is braked to be highest, given when vehicle level-one is braked
People brings more comfortable feel, while greatly shortens the braking response time, improves the security of traveling.Air pressure two stage braking can be with
The output of big braking torque is realized come the stopping so that vehicle further slows down, simultaneously because low speed air-pressure brake can also save brief biography
The ABS system of system is to reduce the complexity of whole braking system.The stationary performance of the existing electromagnetic braking of the device, quick performance,
Security performance and Green performance, and the advantages of conventional gas braking can produce big braking moment is absorbed, while the present apparatus has
Dynamic response performance is good, compact-sized, and arrangement is convenient, can share brake load reduction with other systems integrated control and rub
The advantages that wiping secondary abrasion.Device is additionally provided with power-off failure defencive function, can since device employs the scheme of composite braking
It is with good economic efficiency and social to ensure the security of the lives and property of driver to greatly improve the safety coefficient of device
Benefit, is suitably promoted the use of.
Finally it should be noted that：The above descriptions are merely preferred embodiments of the present invention, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify the technical solution described in foregoing embodiments, or to which part technical characteristic
Carry out equivalent substitution.Where within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
