Description
Technical field
The present invention relates to a kind of break that is installed on the car, car is braked and slowed down.
Background technique
Traditional friction brake is divided into two types of disk type braker and drum brakes on the car, utilizes friction between brake slipper and brake disc or the brake drum to reduce the speed of a motor vehicle and finally stops.Friction brake commonly used at present is main with disk type braker again, promotes the piston motion in the braking clamp body through hydraulic oil, and piston is pressed to brake disc to brake slipper, and both produce frictional force and realize braking.
Under the operating mode of high vehicle speeds, brake not only the wearing and tearing of the brake shoe of friction brake terribly, and can produce a lot of harmful dusts.Simultaneously, friction also can produce a large amount of noises between brake slipper and the brake disc.Automobile is when emergency braking, and the action time of break and braking force are very big to the influence of braking ability, and there are shortcomings such as response is sluggish, control accuracy is low in the hydraulic circuit of disk type braker, causes Braking efficiency to reduce.In lasting braking processs such as lower long slope, or under frequent braking situation, brake temperature sharply rises, and produces " thermal failure ", and Braking efficiency reduces even complete obiteration.Therefore, there is potential safety hazard in friction catch.
One Chinese patent application number 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 prone to forfeiture during control.
Summary of the invention
In view of the problem that existing technology exists, the invention provides a kind of friction and electromagnetism integrated arrestor of simple in structure, speed of response is fast, control accuracy is high double plate chip architecture, improve response capability and the precision of control of automobile when happening suddenly emergency braking.
The technological scheme that the present invention adopts is: have first brake disc and second brake disc; Brake calipers is arranged on the first braking disc; On second brake disc electro-magnetic braking device is set; Electro-magnetic braking device comprises several groups of field coils, and every group of field coil is made up of individual coil winding and 2 iron cores, and coil winding is wound on the iron core; 2 coil winding and 2 iron cores are symmetrically distributed in the both sides of 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 to descend or even completely lose braking ability, has brake safe hidden danger.Two disc brake discs of integrated friction of the present invention and electromagnetism can have been realized the shunting of braking heat through the braking moment of accurate control distribution electromagnetic brake and frictin braek, can avoid braking thermal failure, have improved the vehicle braked Safety performance.
2. the present invention utilizes contactless electromagnetic braking to share the part braking moment; Electromagnetic braking is contactless braking; Wearing and tearing can be effectively alleviated and noise and dust can't be produced; Effectively prolong friction brake working life, improved the heat resistanceheat resistant decline performance of break, improved the Economy and the feature of environmental protection that vehicle uses.
3. car is at a high speed and under the non-emergent operating mode, the driver at first launches the speed of a motor vehicle that electromagnetic brake reduces car, launches friction brake again, and the access times of the break of can reducing friction like this prevent 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 the replacement cycle and the maintenance cost of friction plate.Also reduce the temperature of friction brake, also improved the braking ability of passenger car when high speed simultaneously.
5. the present invention's various masters/passive braking function in the braking system that is easy to upgrade, as TCS etc., be easier to automobile brake and develop towards intelligent and integrated direction.

Among the figure: 1-first brake disc; The 2-coil brace; The 3-nut; The 4-coil winding; The 5-bolt; 6-second brake disc; The 7-aluminium brackets; The 8-iron core; The 9-brake calipers.
Embodiment
As shown in Figure 1; The present invention has two brake discs; Be respectively first brake disc 1 and second brake disc 6, the one chip brake disc of the disc type friction brake that these two brake disc dish replacements are traditional keeps 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 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 2 coil winding 4 and 2 iron cores 8, and coil winding 4 is wound on the iron core 8, and 2 coil winding 4 and 2 iron cores 8 are symmetrically distributed in the both sides of second brake disc 6.2 coil winding 4 are fixedly mounted on coil brace 2 through bolt 5, nut 3, and coil brace 2 is fixed on the car body.When coil winding 4 feeds electric current; Producing exciting field acts on second brake disc 6; According to electromagnetic principle, when second brake disc 6 rotated, the meeting cutting magnetic induction line also produced electromagnetic torque; Hinder second brake disc 6 and rotate, make that friction brake force and electromagnetic system power can brakings jointly on the biplate brake disc simultaneously.
The present invention has four groups of field coils, and totally 8 coil winding 4 are distributed in the both sides of second brake disc 6, and four groups of field coils distribute along the circumferencial direction equal angles of second brake discs 6, and angle is 60 °.In order to prevent that 2 coil winding on the same coil brace 2 from forming field circuit, is equipped with aluminium brackets 7 in the middle of 2 coil winding 4.
When automobile normal running, the brake calipers 9 of friction braking system is in separated state, does not work; Coil winding 4 no electric circuits, no current, do not have magnetic induction line to pass through on second brake disc 6 this moment, and electromagnetic braking is not worked yet.
When automobile need be braked, the driver stepped on brake petal, and electro-magnetic braking device receives brake petal place input signal, the electric current of demand working coil winding then 4.The electromagnetic field that coil winding 4 energising backs produce is distributed in the both sides of second brake disc 6, and second brake disc 6 rotates cutting magnetic induction line, produces electric current, and in magnetic field, receives the effect of electromagnetic force.Second brake disc, 6 cutting magnetic induction lines form eddy current simultaneously, and the magnetic field superposition with coil winding 4 produces more strengthens magnetic intensity, thereby can produce a bigger braking moment to second brake disc 6, reach the effect to car deceleration and braking.Meanwhile, friction braking system promotes piston through hydraulic circuit and brake calipers 9 is pressed to first brake disc 1 brakes; At this moment, friction catch only provides part braking force, and most of braking force is born by electromagnetic braking.When the speed of a motor vehicle is low, adopt friction catch to come abrupt deceleration vehicle; When the speed of a motor vehicle was too high, electromagnetic braking and friction catch acting in conjunction can make automobile stop very soon; When automobile goes with the normal speed of a motor vehicle, when need not emergency braking, can let electromagnetic braking effect earlier that the speed of a motor vehicle is reduced, utilize brake drag effect to come abrupt deceleration vehicle then.
