Abstract
The utility model discloses a brake control device of an automobile, which comprises a brake pedal, a main brake, an eddy current retarder and a position sensor for detecting displacement of the brake pedal. The position sensor is electrically connected with the eddy current retarder and detects the displacement of the brake pedal within a range of idle stroke. By the aid of the brake control device of the automobile, operating intensity of a driver is reduced while working times of the main brake are decreased, the service lives of quick-wear parts of a brake system are prolonged and accordingly, safety of the automobile in running is improved.
Description
Technical field
The utility model relates to vehicle brake technology, especially relates to a kind of vehicle brake technology that adopts current vortex retarder.
Background technology
Existing a lot of vehicles are installed current vortex retarder, carry out auxiliary braking through current vortex retarder.The mechanical electric apparatus unit of current vortex retarder is controlled by control unit; This control unit receives the operating switch information of vehicle driver with the hand input; Perhaps receive the footbrake pedal information of chaufeur; Air pressure by master cylinder produces is opened pressure switch, according to the break-make of this switch control stator coil.No matter be to spoil brake pedal manipulation with manual manipulation or with pin, all exist some drawbacks, such as with hand, chaufeur just can not the two hand-tight bearing circle of holding, and increase labour intensity etc.By the baroswitch foot control, can not realize that again retarder works alone in main brake in advance, can not reduce the friction of main brake sheet.
Summary of the invention
The technical matters that the utility model will solve is to overcome above defective, proposes a kind of vehicle brake control setup, reduces driver's operation, reduces the work number of times of main brake.
The technical scheme of the utility model is; A kind of vehicle brake control setup; Comprise brake pedal, main brake device, current vortex retarder; Also comprise the position induction device that detects the brake pedal displacement, said position induction device is electrically connected with current vortex retarder, and said position induction device detects the displacement of brake pedal in the idle travel scope.
Said position induction device comprises the micro-switch that is electrically connected with the controller of current vortex retarder.
The beneficial effect that the utility model and prior art contrast are had is: when chaufeur gently touches on the brake pedal with pin; Be installed in the interior displacement of idle travel scope that the interior position induction device of brake pedal idle travel scope can detect pedal; Send signal and give the retarder controller; Let retarder mention in foundation brakes work, car retardation.If chaufeur is no longer firmly adopted pedal, main brake is not worked, only retarder work.Not only meet existing driving habit, reduce the manipulation strength of chaufeur, and reduced the work number of times of main brake, prolonged the life-span of brake system consumable accessory, thereby improve the safety of vehicle '.
Description of drawings
Fig. 1 is the constructional drawing of the specific embodiment.
The specific embodiment
A kind of vehicle brake device as shown in Figure 1 comprises brake pedal 1, main brake device 2, position induction device, current vortex retarder 5, and position induction device comprises position converyer 3, micro-switch 4.Position converyer 3 is connected with brake pedal 1, and the displacement of brake pedal 4 is passed to micro-switch 4, and micro-switch 4 changes position signal into electric signal again and is transferred to current vortex retarder 5.Position induction device can receive the idle travel displacement of brake pedal 1, and said idle travel is meant that at brake pedal in the trip, the main brake device is failed to receive brake signal and worked.
Above-mentioned vehicle braked method is, after chaufeur was gently stepped on brake pedal 1, micro-switch was sent out 4 and gone out the controller that signal is given current vortex retarder 5, and the controller of current vortex slow 5 is connected first group of excitation coil, first group of excitation coil energising work, car retardation; If chaufeur no longer continues firmly push down on the pedal 1, main brake 2 is not worked, only first group of excitation coil work of current vortex retarder; If chaufeur keeps this position to surpass setting-up time like 0.25 second or 0.5 second, then the controller of current vortex slow 5 is connected second group of excitation coil again simultaneously, and second group of excitation coil energising work adds hard braking.The controller of current vortex slow 5 can pass through software or a plurality of gears of hardware setting, like four gears, keeps the time of idle travel normal danger to connect 1～4 group of excitation coil successively according to chaufeur, increases the weight of braking action power.Can control braking strength well like this.
When continuing to step on brake pedal 1, after surpassing the brake pedal idle travel, 2 brakings of vehicle main brake.Like this brake process is divided into two parts, the brake little to intensity just can meet the demands through retarder, prolonged the life-span of main brake, improved the safety of vehicle.
Above content is the further explain that combines concrete embodiment that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.
Claims (2)
