Abstract
The invention relates to an electronic parking braking system with double-piston calipers. The electronic parking braking system comprises an EPB actuator and the double-piston calipers, and the EPB actuator is used for driving the double-piston calipers. The system further comprises an electronic control unit used for controlling the current direction and intensity of a motor in the EPB actuator. The electronic parking braking system which is of the structure and is provided with the double-piston calipers is adopted, as the calipers used are double-piston calipers and are different from single-piston calipers used in the current market, the double-piston calipers can provide larger brake force in the same hydraulic system, and therefore the double-piston calipers are used in medium and large vehicles and other vehicles high in requirement for brake performance more frequently. By means of the provided EPB actuator and the double-piston caliper parking mode, the application field and range of novel EPB are enlarged.
Description
Technical field
The present invention relates to electronic parking technical field, particularly relate to double-piston electronic parking system clamp technical field, specifically refer to a kind of electronic brake system with double-piston clamp.
Background technology
Along with development and the progress of science and technology, the requirement of vehicle safety is grown with each passing day by people, and important evaluation that the chassis Comprehensive Control Technology of the braking ability of excellence and integration is Hyundai Motor safety indicates.Along with the development of mechanical & electrical technology, electronic technology constantly penetrates into brake system of car, occurs in that automobile electronic parking braking system (EPB:ElectronicParkingBrake).Electronic brake system be adopt machine driving and automatically controlled mode and motor drive and implement parking braking, there is static parking braking, dynamic emergency brake, ramp start assisting, emergency brake, the features such as unblock, warning of meeting an urgent need.At present, electronic brake system is commonly used on high-grade car at home and abroad, and the trend that oriented middle low gear vehicle is universal.
Electronic brake system is broadly divided into two big classes according to the feature of actuator structure: one is stay-supported electronic brake system, it is driven telescopic lever to move back and forth by a motor-driven mechanism, thus straining or unclamping the brake cable being connected with this telescopic lever to realize the clamping of brake caliper on wheel or to unclamp, implement parking braking or releasing；Two is EPB actuator and clamp integrated type electrical parking braking system, and its principle is that motor drive actuator acts on the piston of brake caliper to implement parking braking.For the characteristic of two kinds of structures, cable traction formula electronic brake system has simple in construction, cost is low, be conducive to the feature such as universal of vehicle；Integrated type electrical parking braking system has compact conformation, volume is little, control the features such as accurate.
Current EPB actuator and clamp integrated type electrical parking braking system all adopt single-piston formula clamp to realize parking function, single-piston clamp cannot meet the vehicle of bigger demand braking force, especially some large-tonnage commercial car, therefore the range of application of single-piston clamp EPB is restricted.The clamp used in the present invention are dual Piston clamp, not only expand the scope of application of EPB actuator, additionally aid the universal of EPB and promote.
Summary of the invention
It is an object of the invention to the shortcoming overcoming above-mentioned prior art, it is provided that a kind of integrated form EPB actuator can match with dual Piston clamp and realize the electronic brake system with double-piston clamp of parking function.
To achieve these goals, the electronic brake system with double-piston clamp of the present invention has following composition:
This has the electronic brake system of double-piston clamp, and it is mainly characterized by, and described system includes EPB actuator and double-piston clamp, and described EPB actuator is in order to drive described double-piston clamp.
It is preferred that described EPB actuator includes motor, drive mechanism, output mechanism, described motor is connected with described output mechanism by described drive mechanism, and described output mechanism is connected with described double-piston clamp.
More preferably, a piston in the clamp that described double-piston clamp are corresponding is provided with screw drive mechanism, exports for parking power.
More preferably, described system also includes electronic control unit, and described electronic control unit is in order to control the sense of current and the size of motor in described EPB actuator.
Further, described system also includes parking switch, and the signal input part of described parking switch is connected with described electronic control unit.
Yet further, described electronic control unit is also in order to receive the output signal of described parking switch.
Further, described electronic control unit also carries out communication with engine signal, belt signal, brake signal and car door signal, GES.
It is preferred that the end of described double-piston clamp is connected to brake block, described brake block is at the action clamping of described double-piston clamp or releasing of brake dish.
Have employed the electronic brake system with double-piston clamp in this invention, the clamp used are double-piston clamp, it is different from the single-piston clamp used in the market, because double-piston clamp can provide bigger brake weight in identical hydraulic system, so double-piston clamp use more in medium-and-large-sized car and the vehicle that braking quality requirement is high；EPB actuator provided by the invention and dual Piston clamp parking mode significantly increase application and the range of application of new E PB.

Detailed description of the invention
In order to more clearly describe the technology contents of the present invention, conduct further description below in conjunction with specific embodiment.
The present invention is made up of parking switch, ECU (electronic control unit), EPB actuator and double-piston clamp, EPB actuator 1 is fixed on double-piston clamp 2, the piston movement in double-piston clamp 2 is driven by EPB actuator 1, brake block 3 is made to be subjected to displacement, clamping or releasing of brake dish 4, thus realizing parking and parking release function.
In the present invention ECU receive and judge from EPB switch, electromotor, seat belt, brake, car door signal, then control to lead to the sense of current and the size of motor in EPB actuator.
The present invention is led to the sense of current of motor in EPB actuator by control and is controlled the forward and reverse of motor.When motor rotates forward, EPB actuator drives the piston in double-piston clamp 2 to be displaced outwardly, and makes the gap between two brake blocks 3 in double-piston clamp 2 reduce, thus clamping brake disc 4, it is achieved parking function；When motor reversal, EPB actuator drives the piston in double-piston clamp 2 to move inward, and makes the gap between two brake blocks 3 in double-piston clamp 2 increase, thus releasing of brake dish 4, it is achieved parking release function.
Have employed the electronic brake system with double-piston clamp in this invention, the clamp used are double-piston clamp, it is different from the single-piston clamp used in the market, because double-piston clamp can provide bigger brake weight in identical hydraulic system, so double-piston clamp use more in medium-and-large-sized car and the vehicle that braking quality requirement is high；EPB actuator provided by the invention and dual Piston clamp parking mode significantly increase application and the range of application of new E PB.
In this description, the present invention is described with reference to its specific embodiment.But it is clear that still may be made that various amendment and conversion are without departing from the spirit and scope of the present invention.Therefore, specification and drawings is regarded in an illustrative, rather than a restrictive.
