The invention has the beneficial effects as follows, the braking effect that when facing a danger, drive simulating person's foot produces when stepping on brake pedal, it is particularly suitable for use with motor bus or the truck of Pneumatic braking system, cost is controlled, easy for installation, beneficially automatic bumper for car is that automobile factory supports the use as the standard configuration of automobile.
Accompanying drawing explanation
Fig. 1 is the pneumatic actuator annexation schematic diagram with former car brakes of the present invention.
Fig. 2 is the schematic diagram of the pneumatic actuator of the present invention.
Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
The pneumatic actuator of the present invention is divided into trailing wheel actuator and front-wheel actuator two parts, sees Fig. 1 with the annexation of former car Pneumatic braking system.
The pneumatic actuator concrete pipeline annexation of the present invention sees Fig. 2.In figure, fine line 13 represents wirning harness.First main brake valve baroswitch 9 and the second main brake valve baroswitch 9-1 is connected by the holding wire in wirning harness 13, gathers the signal of operator brake, exports the signal of telecommunication from wirning harness plug 14；With the coils from parallel connection of coils of the first beam electromagnetic valve 6 after the coils connected in series of the first beam electromagnetic valve baroswitch 7 and the second beam electromagnetic valve 11, obtained from wirning harness plug 14 by wirning harness 13 and drive power supply.Braking trachea between trailing wheel gas outlet and former car Brake lamp signal baroswitch 2 air inlet of former car main brake valve 10 is blocked, the gas outlet of the first two-way valve 8 it is sequentially ingressed into from the inlet port of former car Brake lamp signal baroswitch 2, one air inlet of the first two-way valve 8 and the first main brake valve baroswitch 9, be connected in series on former car braking trachea；Another air inlet of first two-way valve 8 is sequentially ingressed into first beam electromagnetic valve baroswitch the 7, first beam electromagnetic valve 6 and is connected with a port of threeway 5, forms trailing wheel actuator.Trachea between front-wheel gas outlet and the air inlet of former car quick release valve 15 of former car main brake valve 10 is blocked, it is sequentially ingressed into the second main brake valve baroswitch 9-1, an air inlet of the second two-way valve 12 and the gas outlet of the second two-way valve 12 from the front-wheel outlet port of former car main brake valve 10, is connected in series on the air inlet of former car quick release valve 15；Another import of second two-way valve 12 accesses the second beam electromagnetic valve 11, is connected with another port of threeway 5, forms front-wheel actuator.The air inlet pipe of front and rear wheel pneumatic actuator is converged at threeway 5, assists inflator 3 to connect by trachea 4 and former car。First main brake valve baroswitch 9 and the second main brake valve baroswitch 9-1 backups each other, to improve reliability.Can be with any one therein, it is also possible to both with (as shown in Figure 2).
In such scheme, the first beam electromagnetic valve 6 and the second beam electromagnetic valve 11 use electric Proportion valve, make Braking mode dynamics continuously adjustabe, to reach the purpose of hommization Braking mode.
In such scheme, when the controller of automatic bumper for car sends Braking mode signal, the first beam electromagnetic valve 6 is opened, and trailing wheel pneumatic actuator starts Braking mode prior to front-wheel pneumatic actuator, the reserved brake coordination time, to ensure the insensitivity of automobile.
The pneumatic actuator operation principle of the present invention is described as follows, trailing wheel pneumatic actuator Braking mode process: the air inlet of the gas outlet → former car Brake lamp baroswitch 2 → former car relay valve 1 of air inlet → the first two-way valve 8 of gas outlet → the second beam electromagnetic valve baroswitch 7 → the first two-way valve 8 of the air inlet → the first beam electromagnetic valve 6 of the compressed air → the first beam electromagnetic valve 6 of former car auxiliary inflator 3, trigger former back wheels of vehicle brakes, it is achieved Braking mode.Front-wheel pneumatic actuator Braking mode process: during trailing wheel pneumatic actuator Braking mode, the first electromagnetic valve baroswitch 7 turns on after sensing certain air pressure, opens the second beam electromagnetic valve 11.The gas outlet of the air inlet → former car quick release valve 15 of the gas outlet → former car quick release valve 15 of gas outlet → the second two-way valve 12 air inlet → the second two-way valve 12 of the air inlet → the second beam electromagnetic valve 11 of the compressed air → the second beam electromagnetic valve 11 of former car auxiliary air tank 3 → trigger former Herba Plantaginis wheel brake system, it is achieved Braking mode.
If driver's brake pedal, promote former car main brake valve 10, first main brake valve baroswitch 9 or the second main brake valve baroswitch 9-1 turns on after sensing air pressure, a signal will be exported to the controller of automatic bumper for car, automatic bumper for car can release Braking mode immediately, to ensure the operating right authority higher than automatic bumper for car Braking mode of driver.
