Description
Technical field
The present invention relates to vehicular spare parts device field, be specifically related to a kind of brake device for car.
Background technology
Along with progress and the expanding economy of science and technology, the living standard of people improves gradually, and the use amount for automobile is also increasing.Automobile has become the important vehicle of people's trip.People also more and more pay attention to for the safety of automobile.Wherein service brake is an important content of vehicle safety.Existing service brake mode generally adopts plate disc brake.Plate disc brake is that the mode utilizing brake disc both sides piston promotion brake facing and brake disc to rub is braked.But this drg only can make tire stop operating.When automobile driving speed is too fast, even if tire stops operating, but due to the effect of inertia, automobile still can advance a segment distance, is easy to cause traffic accident.
Summary of the invention
The object of the present invention is to provide a kind of brake device for car reducing automobile brake distance.
For achieving the above object, base case of the present invention is as follows: a kind of brake device for car, comprise pivot shaft, roller, spring, be arranged on sensor on tire and controller, described pivot shaft two ends are equipped with the attaching parts that can be arranged on automotive frame, and described pivot shaft is provided with telescopic push rod; Described roller is provided with magnetic part; Described spring one end is connected with pivot shaft, and the other end is connected with roller; Pivot shaft is provided with the electromagnet that the part that is magnetic coordinates, and described electromagnet is connected with the shifter in controllable current direction; Described shifter and sensor are all electrically connected with controller.
Principle of work of the present invention and beneficial effect are: this device is arranged on automotive frame by attaching parts, together travels with automobile.Pivot shaft is parallel to the ground.When running car, in a state of nature, it is contrary with magnetic part magnetic pole, and the two is attracting, and now roller leaves ground, and spring is in compressive state for electromagnet.After chaufeur steps on service brake, motor tire stops operating, then after sensor detects that tire stops operating, by signal transmission to controller, controller controls the direction of current that shifter switches electromagnet, and now electromagnet pole changes, electromagnet is identical with magnetic part magnetic pole, the two repels each other, then magnetic part is away from electromagnet, and magnetic part drives roller to move, spring elongation, roller and earth surface, increase the friction force on automobile and ground, automobile brake distance reduced.When automobile restarts, sensor detects tyre rotation, and by signal transmission to controller, controller controls shifter and again switches electromagnet current direction, and make electromagnet contrary with magnetic part magnetic pole, magnetic part moves to electromagnet, make roller leave ground, be convenient to running car.
Preferred version one: based on the preferred version of scheme, described magnetic part is permanent magnet, and permanent magnet magnetism not easily disappears, more stable.
Preferred version two: the preferably preferred version of, described shifter comprises the first transistor and transistor seconds; Described the first transistor is all connected with controller with transistor seconds, the direction of transistor controllable current, thus by controller control the first transistor and transistor seconds respectively opening and closing control direction of current in electromagnet thus control.
Preferred version three: based on the preferred version of scheme or any one of preferred version one-two, described roller is provided with some steel sands, and steel sand can make roller surface more coarse, and when making roller and earth surface, friction force increases, and reduces its stopping distance.
Accompanying drawing explanation
Fig. 1 is the structural representation of brake device for car embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: roller 1, pivot shaft 2, controller 3, shifter 4, sensor 5, push rod 6, spring 7, permanent magnet 8, electromagnet 9.
Embodiment is substantially as shown in Figure 1: a kind of brake device for car, comprise pivot shaft 2, roller 1, spring 7, be arranged on sensor 5 on tire and controller 3, pivot shaft 2 two ends are all fixedly connected with the attaching parts that can be arranged on automotive frame, pivot shaft 2 are fixedly connected with telescopic push rod 6; Roller 1 is provided with magnetic part; Spring 7 one end is connected with pivot shaft 2, and the other end is connected with roller 1; Pivot shaft 2 is provided with the electromagnet 9 that the part that is magnetic coordinates, electromagnet 9 is connected with shifter 4; Shifter 4 and sensor 5 are all electrically connected with controller 3.Magnetic part is permanent magnet 8, and permanent magnet 8 magnetic not easily disappears, more stable.Shifter 4 comprises the first transistor and transistor seconds; The first transistor and transistor seconds are all connected with controller 3, the folding of transistor controllable current, thus by controller 3 control the first transistor and transistor seconds respectively opening and closing control direction of current in electromagnet 9 thus control.Roller 1 is welded with some steel sands, and steel sand can make roller 1 surface more coarse, and when making roller 1 and earth surface, friction force increases, and reduces its stopping distance.
This device is arranged on automotive frame by attaching parts, together travels with automobile.Pivot shaft 2 is parallel to the ground.When running car, electromagnet 9 is contrary with permanent magnet 8 magnetic pole, and the two is attracting, and now roller 1 leaves ground, and spring 7 is in compressive state.After chaufeur steps on service brake, motor tire stops operating, then after sensor 5 detects that tire stops operating, by signal transmission to controller 3, controller 3 controls the direction of current that shifter 4 switches electromagnet 9, and now electromagnet 9 magnetic pole changes, electromagnet 9 is identical with permanent magnet 8 magnetic pole, the two repels each other, then permanent magnet 8 is away from electromagnet 9, and permanent magnet 8 drives roller 1 to move, spring 7 stretches, roller 1 and earth surface, increase the friction force on automobile and ground, automobile brake distance reduced.When automobile restarts, sensor 5 detects tyre rotation, and by signal transmission to controller 3, controller 3 controls shifter 4 and again switches electromagnet 9 direction of current, make electromagnet 9 contrary with permanent magnet pole, permanent magnet 8 moves to electromagnet 9, makes roller 1 leave ground, is convenient to running car.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in specification sheets etc. record the content that may be used for explaining claim.
