The specific embodiment
(embodiment 1)
See Fig. 1, the brake pedal apparatus of the automobile line control brake system of present embodiment comprises brake pedal 1, pedal arm 2, support 3, pedal displacement sensor 4, Connector Clip 5 and pedal pressing force sensing and sense simulator 6.
Support 3 is fixed on the chassis of automobile in use.Support 3 is provided with pilot hole, and the guiding hole size cooperates with the crest clearance of push rod 61.The upper end of pedal arm 2 is rotatably connected on the support 3 by bearing pin, and brake pedal 1 welding is fixedly connected on the lower end of pedal arm 2.
See Fig. 2, pedal pressing force sensing and sense simulator 6 comprise housing 60 and the push-rod piston 62, piezoelectric element 63, insulating sleeve 64, pull back spring 65, primary piston 66, inboard spring 67-1, outside spring 67-2 and the base 68 that are arranged in the housing 60, also comprise push rod 61 and initial tension of spring adjusting knob 69.
Push-rod piston 62 is the steel integral piece, comprise and be positioned at anterior large cylinder and be connected on the large cylinder and the small cylinder large cylinder coaxial line from the rear, the large cylinder sidepiece periphery of push-rod piston 62 matches with the sidewall of housing 60, push-rod piston 62 is by its large cylinder and housing 60 front and back sliding block joints, the small cylinder sidepiece periphery of push-rod piston 62 matches with the madial wall of insulating sleeve 64, and the rear portion of the small cylinder of push-rod piston 62 is stretched in the insulating sleeve 64 backward.
Pull back spring 65 is the steel stage clip, and internal diameter is greater than the external diameter of insulating sleeve 64, and pull back spring 65 is enclosed within outside the insulating sleeve 64, between the front end face of the large cylinder of the aft end face of the large cylinder of push-rod piston 62 and primary piston 66, and is in compressive state.
Insulating sleeve 64 plays insulation and directional tagging, its axial dimension is slightly larger than the minor increment between state of equilibrium lower push-rod piston 62 and the primary piston 66, less than the distance between the front end face of the large cylinder of the aft end face of the large cylinder of push-rod piston 62 and the primary piston under the state of equilibrium 66, thereby make it have good directional tagging, and push-rod piston 62 can normally compress piezoelectric element 63-3 to push-rod piston 62.
By removable being fixed on the housing 60 that be threaded, and base 68 is positioned at housing 60 to base 68 by its three cylindrical body.Inboard spring 67-1 is opposite with outside spring 67-2 rotation direction, and both all are arranged between primary piston 66 and the base 68.Inboard spring 67-1 is enclosed within on the 4th cylinder of primary piston 66 and on first cylinder of base 68, and between the second step face of the second step face of primary piston 66 and base 68, its drift greater than the minor increment between primary piston under the state of equilibrium 66 and the base 68 (be the rearmost end of primary piston 66 and base 68 foremost between distance), less than the distance between the second step face of the second step face of the primary piston under the state of equilibrium 66 and base 68, thereby inboard spring 67-1 only can just can be compressed when primary piston 66 is significantly advanced backward, also is that inboard spring 67-1 only works when hard intensity braking or emergency braking.The elasticity modulus of outside spring 67-2 is greater than the elasticity modulus of pull back spring 65.Outside spring 67-2 is enclosed within on the three cylindrical body of primary piston 66 and on second cylinder of base 68, between the first step face of the first step face of primary piston 66 and base 68, and is in compressive state, all works in whole braking procedure.Because primary piston 66 is subjected to the elastic force effect of pull back spring 65 and outside spring 67-2 simultaneously, both elastic force is cancelled out each other when static, and this moment, primary piston 66 residing states were called state of equilibrium.
Initial tension of spring adjusting knob 69 is fixed on the aft end face of the three cylindrical body of base 68, base 68 can be screwed in or screw out housing 60 by rotating spring predetermincd tension adjusting knob 69.Thereby regulate the resistance of brake pedal with this preload of regulating outside spring 67-2, satisfying the requirement of different automobile types or chaufeur individuality, thereby provide truly and accurately brake feeling at glancing impact.
Pedal displacement sensor 4 adopts two variable rheostats, to improve its signal accuracy and fault-tolerant ability, assurance is to pedal static state or quasistatic is measured accurately and reliability is high, wherein variable rheostat is fixed on by its shell on the position at pilot hole place of support 3, and the slide rail of two variable rheostats is installed in its shell, a upside that is fixed on push rod 61 in two slide plates, another is fixed on the downside of push rod 61, the slide plate of each variable rheostat contacts with the slide rail of each variable rheostat, move along with moving of push rod 61, thereby outwards export the pedal displacement stroke signal.
When automobile brake, chaufeur is stepped on brake pedal 1, and pedal arm 2 left-hand revolutions drive push rod 61 towards the direction motion of trampling, and pedal displacement sensor 4 is owing to moving of push rod 61 exported the pedal displacement stroke signal; The rear end that push rod 61 promotes the push-rod piston 62 of pedal pressing force sensing and sense simulator 6 overcomes the resistance of pull back spring 65 and moves to rear side in insulating sleeve 64, thereby extruding piezoelectric element 63-3 makes its output pedal pressing force signal.After the central processing unit used of matching with this brake pedal apparatus receives pedal pressing force and pedal displacement stroke signal, handle, make chaufeur braking intention and discern, and send the instruction control automobile brake through information fusion.In the information fusion process, pedal is in the pedal pressing force signal that sends based on pedal pressing force sensing and sense simulator 6 when dynamic, the displacement signal that sends based on pedal displacement sensor 4 when pedal is in static state or quasistatic; If have one to break down in two sensors, central processing unit will continue the Control of Automobile braking according to another sensor signal so, and in time the warning reminding chaufeur is repaired as early as possible simultaneously.
In addition, if chaufeur gently steps on brake pedal 1, the inboard spring 67-1 in pedal pressing force sensing and the sense simulator 6 is not because inoperative by compression, and the amount of compression of outside spring 67-2 changes with the variation of pedal displacement stroke; When pedal displacement stroke variation range was big, the variation of pedal brake pressure was steady, and this moment, car retardation was mild, and braking is stablized comfortable; When chaufeur is stepped on brake pedal 1 with high strength or brish acceleration, outside spring 67-2 is sharply compressed, simultaneously inboard spring 67-1 participates in work, the resistance of pedal pressing force sensing and sense simulator 6 sharply increases, this moment, the variation of pedal displacement stroke was less, pedal brake pressure changes sharply, and the car brakeing response shows brake efficiency preferably rapidly.
