Description
Technical field
The present invention relates to a kind of brake system, relate in particular to a kind of automobile brake that is mainly used in to obtain the electronics voussoir brake system of safe Parking.
Background technology
Car brake is meant the parts that produce the power (braking force) that hinders vehicle movement or movement tendency, wherein also comprises the shock absorber in the auxiliary braking system, and car brake generally uses hydraulic efficiency pressure system to control at present; Promptly brake reliability through utilizing hydraulic pressure that liner is pressed dish, perhaps adopt pneumatic system to brake, electric mechanical braking device (EMB) has quite simple structure and good braking; Therefore EMB has obtained using widely; EMB realizes braking through motor power being directly changed into straight-line motion power, but the structure more complicated of electric mechanical braking device, middle connection procedure link is more; Fault rate is bigger; And retro-speed and braking effect are relatively poor relatively, and the car load response time is longer, influences traveling security.
Summary of the invention
Deficiency to the prior art existence; Technical matters to be solved by this invention is; A kind of simplification brake system structure is provided, improves retro-speed and braking effect, and reduce fault rate, effectively reduce Parking response time and improve the electronics voussoir brake system of travel safety.
For solving the problems of the technologies described above; The technical scheme that the present invention taked is: a kind of electronics voussoir brake system; Comprise central controller and be located at the electronics voussoir drg on each wheel respectively; It is characterized in that: also comprise the motor driver that is electrically connected with central controller, the electronics voussoir drg of said each wheel all is electrically connected with motor driver, on central controller, connects electronic brake pedal and Parking emergency braking controller.
Above-mentioned electronics voussoir brake system is equipped with on said each wheel and the corresponding electronics tachogen in order to the collection vehicle wheel rotational speed of the gear ring of wheel, and said each electronics tachogen all is electrically connected with central controller.
The advantage of electronics voussoir brake system of the present invention is: this system integration the existing straight air brake system abs braking system that unifies, the two is united two into one, can greatly simplify existing brake system structure; And electronization, automation completely, and reasonable in design, adopt wire harness to connect; Easy-to-connect; Adopt central controller as processing enter, intelligent degree is high, and the motor driver that is electrically connected with central controller is set; Individual electronics voussoir drg is controlled accurately and timely; Adopt the detection of electronics wheel speed sensors to wheel, improved the accuracy of Parking control greatly, that the present invention efficiently solves that traditional mechanical formula emergency brake system exists is high to the chaufeur technical requirements, brake-force transmission gap, the low adhesion value road surface of mechanical system and the uphill starting operation easier is big and multiple practical problems such as result of use difference.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is explained further details;
As shown in Figure 1; A kind of electronics voussoir brake system; Comprise central controller 1 and be located at the electronics voussoir drg 3 on front left wheel 21, right front wheel 22, left back wheel 23 and the right rear wheel 24 respectively; Also comprise the motor driver 4 that is electrically connected with central controller 1; Electronics voussoir drg 3 on front left wheel 21, right front wheel 22, left back wheel 23 and the right rear wheel 24 all is electrically connected through wire harness 9 with motor driver 4, on central controller 1, connects electronic brake pedal 5 and Parking emergency braking controller 6.Be equipped with the gear ring of each wheel 7 correspondingly in order to gather the electronics tachogens 8 of vehicle wheel rotational speed on front left wheel 21, right front wheel 22, left back wheel 23 and the right rear wheel 24, each electronics tachogen 8 all is electrically connected through wire harness 9 with central controller 1.
Electronic brake pedal 5, Parking emergency braking controller 6 are positioned at operator's compartment, and electronic brake pedal 5 is positioned at the bottom of the chaufeur right crus of diaphragm, and Parking emergency braking controller 6 is positioned at the place that the chaufeur right hand conveniently touches.The braking instruction that the electronic brake pedal 5 of chaufeur control sends is transferred to ECU by wire harness 9, and promptly central controller 1, handles after motor driver 4 sends instruction for the drive motor of EWDB (electronics voussoir drg 3) through ECU, implements service brake.The electronics tachogen 8 that is installed on the wheel is gathered the wheel information that gear ring 7 is passed on, and feeds back to ECU, implements the closed loop control to EWDB.Break down when needing to implement emergency braking when Parking or service brake, pilot control Parking emergency braking controller 6 sends braking instruction to ECU, handles after motor driver 4 sends instruction for the drive motor of EWDB through ECU, implements braking during standstill.
Drive motor on the electronics voussoir drg (EWDB) is according to the instruction output corresponding torque of motor driver 4; And be converted into retrothrust through transmission device; Again by wherein brake clearance automatic regulator cotter mechanism thrust is converted into the thrust to shoes of vertical direction, vehicle is implemented braking.When having excessive gaps between friction lining and the brake wheel, automatic gap adjustment device can be eliminated excessive gaps automatically, makes the gap keep steady state value.This drg is applicable to vehicles such as all kinds of medium and heavy bogies.
Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited to above-mentioned giving an example; Those skilled in the art; In essential scope of the present invention, the variation of making, remodeling, interpolation or replacement all should belong to protection scope of the present invention.
