Description
Technical field
This utility model relates to automobile brake technical field, particularly relates to a kind of planetary gear type electric control parking brake.
Background technology
At present, China's automobile pollution sustainable growth, automobile plays very important role the most in daily life.
In motor vehicles parking braking system, especially in electronic brake system, rear clamp Integral electronic parking brake function is many, easy for installation, and therefore growth momentum is swift and violent.The power resources of the electric parking brake of this type of form are motors, and power, through reducing gear, is passed to brake caliper assembly, and then completes the parking braking to vehicle by described motor.
Existing parking braking system, on the one hand, the motor of employing not only volume is relatively big, and needs often to safeguard；On the other hand, reducing gear volume is the biggest, and kinetic equation loss is high, and transmission efficiency is low, does not meets present electric control parking brakes miniaturization and efficient requirement.
Utility model content
In order to solve the problems referred to above, the purpose of this utility model is the planetary gear type electric control parking brake providing a kind of compact conformation, transmission efficiency high.
For achieving the above object, this utility model is by the following technical solutions:
A kind of planetary gear type electric control parking brake, including body electronics stabilisation systems, electric control parking brake system control unit, brshless DC motor, planetary reducer, piston screw mechanism, more than two panels brake strip and the brake disc being located between brake strip, body electronics stabilisation systems is connected by CAN with electric control parking brake system control unit, electric control parking brake system control unit controls brshless DC motor start and stop, brshless DC motor drives planetary reducer, planetary reducer drives piston screw mechanism, piston screw mechanism urges brake strip is combined with brake disc.
Wherein, described brshless DC motor is permanent-magnet brushless DC electric machine.
Wherein, described piston screw mechanism includes the Thrust nut that screw rod engages and the piston being set in outside Thrust nut with screw rod.
This utility model has the advantages that
1) brshless DC motor uses permanent-magnet brushless DC electric machine, and volume is little, non-maintaining, controls accurately；
2) using planetary reducer, compact conformation, transmission efficiency is high.

1-body electronics stabilisation systems, 2-electric control parking brake system control unit, 3-brshless DC motor, 4-planetary reducer, 5-piston screw mechanism, 51-screw rod, 52-Thrust nut, 53-piston, 6-brake strip, 7-brake disc.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further details:
As shown in Figure 1, a kind of planetary gear type electric control parking brake, including body electronics stabilisation systems (ESP system) 1, electric control parking brake system control unit (ECPB control unit) 2, brshless DC motor 3, planetary reducer 4, piston screw mechanism 5, brake strip 6 and brake disc 7；
ESP system 1 is connected by CAN with ECPB control unit 2；
ECPB control unit 2 controls brshless DC motor 3 start and stop；Brshless DC motor 3 uses permanent-magnet brushless DC electric machine, and permanent-magnet brushless DC electric machine volume is little, non-maintaining, controls accurately；
Brshless DC motor 3 drives planetary reducer 4, uses planetary reducer 4, compact conformation, and transmission efficiency is high；
Planetary reducer 4 drives piston screw mechanism 5, as shown in Figure 2, piston screw mechanism 5 includes the Thrust nut 52 that screw rod 51 engages and the piston 53 being set in outside Thrust nut with screw rod, planetary reduction gear drives screw rod to rotate, thus promote Thrust nut the most forward or be moved rearwards by, thus promote piston the most forward or be moved rearwards by；
Piston 53 promotes brake strip 6, brake strip 6 can arrange more than two panels, and brake disc 7 is located between brake strip 6.
ESP system receives electronic brake information, and parking braking information is sent to ECPB control unit, ECPB control unit starts brshless DC motor, brshless DC motor output power, imparting power to piston screw mechanism by planetary reducer after being slowed down, brake strip is ejected by piston screw mechanism, and brake strip combines with brake disc and produces friction, form braking effect, thus effectively promote parking braking safety.
The foregoing is only detailed description of the invention of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure transformation utilizing this utility model description and accompanying drawing content to be made; or directly or indirectly it is used in other relevant technical fields, the most in like manner it is included in scope of patent protection of the present utility model.
