Abstract
An operating system of an automobile brake master cylinder is composed of a signal input device, an electronic controller and an execution mechanism. The signal input device is composed of an automobile speed sensor, a distance measuring sensor, a pedal triggering sensor and a displacement sensor and is responsible for receiving information relevant to automobiles. The electronic controller receives sensor information and judges whether automatic operating control needs to be provided for the brake master cylinder or not. The execution mechanism can use a motor as a power source of a brake system and transmits the drive force of the motor to a push rod of the brake master cylinder through an electromagnetic clutch and a reducing mechanism to replace a driver to achieve brake operation, and the automatic brake of the automobiles is achieved. Due to the facts that only the automatic operating system of the brake master cylinder is aimed and the fact that an existing brake control system aims at four wheel cylinders does not exist, the system is simple in structure, convenient to mount, low in cost, and capable of being widely applied to hydraulic brake automobiles.
Description
Technical field:
The utility model is a kind of automobile brake technology, particularly automobile brake maneuvering system technology.
Background technology:
The master brake cylinder of brake system of car is handled generally and is handled by braking footrest, both finishes by foot's brake activation stretcher of chaufeur.When chaufeur spirit is in tired state or when absent minded, perhaps vehicle travels the big or automobile of density when travelling in the mountain area on the road, and chaufeur need be stepped on brake pedal frequently, and one is careless slightly, vehicle collision or phenomenon to lose control of one's vehicle just may occur.In the prior art, the control position of motor vehicle braking system generally be by electric machine control on the brake wheel cylinder of brake system.Adopt existing technology, owing to be to control at four wheels of automobile, need many cover function uniies, control setup cost height.
Summary of the invention:
The problem that the utility model solves is, overcome disadvantages of background technology, propose a kind of automobile brake maneuvering system, this system can replace chaufeur to the manipulation of braking footrest, automatically finish the manipulation of master brake cylinder push rod by motor, thereby realize the automatic control of the brake system of automobile.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of maneuvering system of automobile braking master cylinder, by motor, magnetic clutch, speed reduction gearing, pinion and rack, electronic controller, braking footrest, push rod, master brake cylinder, car speed sensor, distance measuring sensor, pedal stroke sensor, displacement pickup is formed, the power that it is characterized in that the automobile braking master cylinder maneuvering system can pass to magnetic clutch by output shaft by motor, pass to speed reduction gearing again, then pass to the gear of pinion and rack by the output shaft of speed reduction gearing, pinion and rack passes to power the push rod of master brake cylinder again by tooth bar.The beneficial effects of the utility model are: when chaufeur spirit is in tired state or when absent minded, perhaps vehicle travels the big or automobile of density when travelling in the mountain area on the road, can avoid that chaufeur is not stepped on brake pedal, foot action is slow or foot's maloperation and the vehicle collision that causes or phenomenon to lose control of one's vehicle.Because just at the automatic handling system of master brake cylinder, rather than existing braking control system at 4 wheel cylinders, so simple in structure, easy for installation, cost is low, can be widely used in the automobile of hydraulic braking.
Description of drawings:
Figure is that system of the present utility model constitutes scheme drawing.
The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is done to describe in further detail.
A kind of maneuvering system of automobile braking master cylinder is made up of signal input apparatus, electronic controller, actuating unit.Signal input apparatus comprises that car speed sensor 9, distance measuring sensor 10, pedal trigger sensor 11, displacement pickup 12, actuating unit is made up of push rod 2, the master brake cylinder 3 of motor 7, magnetic clutch 6, speed reduction gearing 5, pinion and rack 4, braking footrest 1, master brake cylinder, electronic controller is made up of controller 8, as shown in the figure.
For this automobile braking master cylinder maneuvering system, displacement pickup is installed on the push rod 2 of master brake cylinder, detects the displacement of push rod; Car speed sensor 9 shares the car speed sensor that former car is equipped with, and detects the speed of a motor vehicle of automobile; Distance measuring sensor 10 is installed in the automobile front beam, detects the distance of front vehicles or obstacle.
For the manipulation of automobile braking master cylinder, can adopt the maneuverability pattern of traditional braking footrest, also can replace braking footrest to finish the manipulation of master brake cylinder by motor.In the automobile braking master cylinder maneuvering system, power can pass to magnetic clutch 6 by output shaft by motor 7, pass to speed reduction gearing 5 again, then pass to the gear of pinion and rack 4 by the output shaft of speed reduction gearing 5, pinion and rack 4 passes to the push rod 2 of master brake cylinder with power by tooth bar again, perhaps directly force transmission is given the push rod 2 of master brake cylinder 3 via braking footrest 1.
Manipulation for automobile braking master cylinder, only receive the signal of car speed sensor 9, distance measuring sensor 10 and judge that automobile has collision risk or danger out of control at electronic controller 8, but do not have the energizing signal that pedal triggers sensor 11 and displacement pickup 12, just provide the curtage signal to motor 7, magnetic clutch 6; If electronic controller 8 receives the signal of car speed sensor 9, distance measuring sensor 10 and judges that automobile has collision risk or danger out of control, but receive the energizing signal that pedal triggers sensor 11 or displacement pickup 12, at this moment do not provide the curtage signal to motor 7, magnetic clutch 6, automobile braking master cylinder 3 adopts conventional braking footrest to handle; If electronic controller 8 does not receive the signal of car speed sensor 9 or distance measuring sensor 10, at this moment do not provide the curtage signal to motor 7, magnetic clutch 6, automobile braking master cylinder 3 adopts conventional braking footrest to handle; If electronic controller 8 does not provide curtage to magnetic clutch 6, the manipulation of master brake cylinder is at this moment finished by braking footrest 1, and namely the braking force of traditional approach is handled.
This automobile braking master cylinder maneuvering system, in order to guarantee that pedal triggers sensor 11 and breaks down the time, the master cylinder maneuvering system still can normal operation, uses displacement pickup 12 and triggers the substitution signal of sensor 11 as pedal, participates in the work control of motor 7 and magnetic clutch 6.
This automobile braking master cylinder maneuvering system, the power of motor 7 outputs is to be delivered to speed reduction gearing 5 via magnetic clutch 6, magnetic clutch can be the alignment coil structures, also can be the moving winding structure.
