Raw " thermal failure " has the shortcomings that potential safety hazard.Therefore, a kind of electromagnetism and the compound disk brake of friction are occurred in that on the market, this
The brake of double plate chip architecture has two kinds of arrestment mechanisms, but tray type structure quality is big, original drive system is affected after installation
Larger, adopt electric current relay grading control more, produced braking moment classification is discontinuous.
Utility model content
In order to overcome existing double disk brake quality big, larger on the impact of original drive system, braking moment is classified not
Continuous not enough, this utility model provides a kind of drum-type composite braking device.
This utility model solves the technical scheme adopted by its technical problem：A kind of drum-type composite braking device, bag
Caliper, brake disc and friction plate is included, caliper is sleeved on the edge of brake disc, and friction plate is arranged on the inwall of caliper,
Brake disc is annular in shape, and disk body is provided with electromagnetic braking face and frictional damping face, is provided with support in brake disc, and support is provided with electromagnetism
Coil.
According to another embodiment of the present utility model, further include that electromagnetic braking face and frictional damping face are located at respectively
On the internal ring wall and card of brake disc.
According to another embodiment of the present utility model, further include that support is cylindrical, positioned at the annular distance of brake disc
Central authorities, concentric with brake disc.
According to another embodiment of the present utility model, further include that support is fixed on the power transmission shaft of vehicle.
According to another embodiment of the present utility model, further include that solenoid is evenly distributed on the circumference of support
On.
According to another embodiment of the present utility model, solenoid is further included towards electromagnetic braking face, both it
Between leave electromagnetism gap.
The beneficial effects of the utility model are to design circlewise brake disc, divide on the internal ring wall of brake disc and card
Not She Zhi electromagnetic braking face and frictional damping face, meanwhile, in the annular distance central authorities of brake disc, cylindric support is set, support is fixed
On the power transmission shaft of vehicle, solenoid being uniformly distributed all over the body, forming drum-type composite braking device, total quality is light, about
The 1/3 of existing disk type electromagnetic brake；Overall dimensions are little, are easy to dismount, and coupling is convenient；Its braking moment for producing can reach
1400Nm, can undertake vehicle major part braking moment, it is thus possible to extend the service life of brake disc, reduce for vehicle system
The maintenance cost of dynamic system, can meet the needs of middle-size and small-size car completely；Also, stepless control method is adopted, with PWM electricity
Road replaces electric current relay to power each solenoid simultaneously, realizes the continuous control to electric current, so as to realize to brake system
The control of kinetic moment, the braking moment consecutive variations of generation, to better adapt to the requirement of vehicle brake technology, keep stable
Car speed, prevents brake overheating.
Description of the drawings
With reference to the accompanying drawings and examples this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is left view of the present utility model.
1. caliper in figure, 2. brake disc, 3. electromagnetic braking face, 4. support, 5. solenoid, 6. friction plate,

Specific embodiment
If Fig. 1 is structural representation of the present utility model, Fig. 2 is left view of the present utility model, and a kind of drum-type is combined
Brake unit, including caliper 1, brake disc 2 and friction plate 6, caliper 1 is sleeved on the edge of brake disc 2, and friction plate 6 is installed
On the inwall of caliper 1, brake disc 2 is annular in shape, and disk body is provided with electromagnetic braking face 3 and frictional damping face 7, in brake disc 2
Support 4 is provided with, support 4 is provided with solenoid 5.Electromagnetic braking face 3 and frictional damping face 7 are located at the internal ring of brake disc 1 respectively
On wall and card.Support 4 is cylindrical, positioned at the annular distance central authorities of brake disc 1, concentric with brake disc 1.Support 4 is fixed on vehicle
Power transmission shaft on.Solenoid 5 is evenly distributed on the circumference of support 4.Solenoid 5 towards electromagnetic braking face 2, between the two
Leave electromagnetism gap.
Brake disc 2 is designed circlewise, electromagnetic braking face 3 is respectively provided with the internal ring wall of brake disc 2 and card and is rubbed
Braking surface 7 is wiped, meanwhile, in the annular distance central authorities of brake disc 2, cylindric support 4 is set, support 4 is fixed on the power transmission shaft of vehicle
On, it is uniformly distributed solenoid 5 all over the body, forms drum-type composite braking device, total quality is light, about existing disk type electromagnetic system
The 1/3 of dynamic device；Overall dimensions are little, are easy to dismount, and coupling is convenient；Its braking moment for producing can reach 1400Nm, can undertake
Vehicle major part braking moment, it is thus possible to extend the service life of brake disc 2, reduce the maintenance cost for motor vehicle braking system
With the needs of middle-size and small-size car can be met completely；Also, stepless control method is adopted, replaces existing electricity with pwm circuit
Current relay is powered simultaneously to each solenoid 5, realizes the continuous control to electric current, so as to realize to brake torque
Control, the braking moment consecutive variations of generation, to better adapt to the requirement of vehicle brake technology, keep stable automobile speed
Degree, prevents brake overheating.
Solenoid 5 is tightened together with the power transmission shaft of vehicle by support 4 so that electromagnetic braking become one independent
Whenever sensitive brakes, can be provided braking moment by the wish of driver, be directly driven using electric current, do not had
Intermediate link, its control response time are very short, only 40 milliseconds, faster than the response time of Retarder 20 times.Work as speed
Using electromagnetic braking come abrupt deceleration vehicle when low；When speed is too high, frictional damping is first passed through, then electromagnetic braking again, can be made
Automobile quickly stops, and greatly improves braking effect.
