Description
Technical field
The present invention relates to a kind of break being arranged on car, car is braked and slowed down.
Background technique
On car, traditional friction brake is divided into disk type braker and drum brake two classes, utilizes the friction between brake slipper and brake disc or brake drum reduce the speed of a motor vehicle and finally stop.At present conventional friction brake, again take disk type braker as main, promotes the piston movement in braking clamp body by hydraulic oil, and piston presses to brake disc brake slipper, and both produce frictional force and realize braking.
Under the operating mode of high vehicle speeds, the wearing and tearing of braking the brake shoe to friction brake are not only very serious, and can produce a lot of harmful dusts.Meanwhile, between brake slipper and brake disc, friction also can produce a large amount of noises.Automobile is in the time of emergency braking, and the action time of break and braking force are very large on the impact of braking ability, and the hydraulic circuit of disk type braker exists the shortcomings such as response is sluggish, control accuracy is low, causes Braking efficiency to reduce.In the lasting braking processs such as lower long slope, or under frequent brake condition, brake temperature sharply rises, and produces " thermal failure ", and Braking efficiency reduces disappearance even completely.Therefore there is potential safety hazard in friction catch.
Chinese Patent Application No. is 201110083620.2, name is called a kind of electromagnetism and rub compound disk type braker and braking method, has adopted magnetic core, coil winding, permanent magnet etc., and its complex structure causes that speed of response is slow, braking ability is easily lost while controlling.
Summary of the invention
In view of the problem that prior art exists, the invention provides friction and the electromagnetism integrated arrestor of a kind of simple in structure, fast response time, double plate chip architecture that control accuracy is high, improve the response capability of automobile in the time happening suddenly emergency braking and the precision of control.
The technical solution used in the present invention is: have the first brake disc and the second brake disc, brake calipers is arranged on the first braking disc, on the second brake disc, electro-magnetic braking device is set, electro-magnetic braking device comprises several groups of field coils, every group of field coil is made up of individual coil winding and 2 iron cores, and coil winding is wound on iron core; 2 coil winding and 2 iron cores are symmetrically distributed in the both sides of the second brake disc, are provided with aluminium brackets in the middle of 2 coil winding.
The invention has the beneficial effects as follows:
1. existing brake system of car adopts monolithic brake disc friction catch, inevitably has the shortcoming of thermal failure, and frequent or long-time use can cause braking ability decline or even completely lose braking ability, has brake safe hidden danger.Two disc brake discs of the integrated friction of the present invention and electromagnetism can, by the accurate braking moment of distributing electromagnetic brake and frictin braek of controlling, have been realized the shunting of braking heat, can avoid braking thermal failure, have improved the brake safe performance of vehicle.
2. the present invention utilizes contactless electromagnetic braking to share part braking moment, electromagnetic braking is contactless braking, wearing and tearing can be effectively alleviated and noise and dust can't be produced, effectively extend friction brake working life, improved the heat resistanceheat resistant decline performance of break, improved Economy and the feature of environmental protection that vehicle uses.
3. car, at a high speed and under non-emergent operating mode, first driver enables electromagnetic brake and reduce the speed of a motor vehicle of car, then enables friction brake, can reduce like this access times of friction brake, prevents that the Braking efficiency of friction brake from reducing.
4. under the operating mode of emergency braking, electromagnetic braking and friction catch are worked simultaneously, electromagnetic braking can be born sizable a part of brake load, so both can reduce the wearing and tearing to friction plate, has reduced replacement cycle and the maintenance cost of friction plate.Also reduce the temperature of friction brake, also improved the braking ability of passenger car in the time of high speed simultaneously.
5. the present invention's various active/passive braking function in braking system that is easy to upgrade, as ABS TCS ESP ACC EBD etc., be easier to automobile brake towards intelligent and integrated future development.

Embodiment
As shown in Figure 1, the present invention has two brake discs, be respectively the first brake disc 1 and the second brake disc 6, these two brake disc dishes replaced to the one chip brake disc of traditional disk type friction brake, retain original friction catch assembly (comprising brake slipper, brake calipers etc.).Brake calipers 9 is arranged on the first braking disc 1, fixedly mounts with car body.Under the control of hydraulic braking pipeline, brake slipper presses the first braking disc 1, the first braking disc 1 and produces friction brake force.
On the second brake disc 6, electro-magnetic braking device is set, electro-magnetic braking device comprises several groups of field coils, every group of field coil is made up of 4 and 2 iron cores 8 of 2 coil winding, and coil winding 4 is wound on iron core 8, and 4 and 2 iron cores 8 of 2 coil winding are symmetrically distributed in the both sides of the second brake disc 6.2 coil winding 4 are fixedly mounted on coil brace 2 by bolt 5, nut 3, and coil brace 2 is fixed on car body.In the time that coil winding 4 passes into electric current, producing exciting field acts on the second brake disc 6, according to electromagnetic principle, in the time that the second brake disc 6 rotates, meeting cutting magnetic induction line also produces electromagnetic torque, hinder the second brake disc 6 and rotate, friction brake force and electromagnetic system power can jointly be braked simultaneously on biplate brake disc.
The present invention has four groups of field coils, and totally 8 coil winding 4 are distributed in the both sides of the second brake disc 6, and four groups of field coils distribute along the circumferencial direction equal angles of the second brake disc 6, and angle is 60 °.In order to prevent that 2 coil winding on same coil brace 2 from forming field circuit, is equipped with aluminium brackets 7 in the middle of 2 coil winding 4.
In the time of automobile normal running, the brake calipers 9 of friction braking system, in separated state, is not worked; Coil winding 4 no electric circuits, no current, does not now have magnetic induction line to pass through on the second brake disc 6, and electromagnetic braking is not also worked.
In the time that automobile need to be braked, driver steps on brake petal, and electro-magnetic braking device receives brake petal place input signal, the electric current of then demand working coil winding 4.The electromagnetic field producing after coil winding 4 energising is distributed in the both sides of the second brake disc 6, and the second brake disc 6 rotates cutting magnetic induction line, generation current, and in magnetic field, be subject to the effect of electromagnetic force.The second brake disc 6 cutting magnetic induction lines form eddy current simultaneously, with the magnetic field superposition that coil winding 4 produces, magnetic intensity are more strengthened, thereby can produce a larger braking moment to the second brake disc 6, reach the effect to car deceleration and braking.Meanwhile, friction braking system promotes piston by hydraulic circuit and brake calipers 9 is pressed to the first brake disc 1 brakes; Now, friction catch only provides part braking force, and most of braking force is born by electromagnetic braking.In the time that the speed of a motor vehicle is low, adopt friction catch to carry out abrupt deceleration vehicle; In the time that the speed of a motor vehicle is too high, electromagnetic braking and friction catch acting in conjunction, can make automobile stop very soon; When automobile travels with the normal speed of a motor vehicle, during without emergency braking, can allow electromagnetic braking first act on the speed of a motor vehicle is reduced, then utilize brake drag effect to carry out abrupt deceleration vehicle.
