Description
Technical field
The present invention relates to a kind of based on motor-driven electric liquid disk-type braking method and device.
Background technique
At present, the braking system that adopts of domestic and international most of automobile also is based on the hydraulic control mechanical pressure and reaches the braking purpose.Since the conventional hydraulic break exist complex structure, component many, take up space, arrange shortcomings such as inconvenience and SYS Ex system expanding be relatively poor.A lot of automotive electronics supply commercial city, the whole world is at the research and development line control brake system, and line control brake system generally is divided into two types, and a kind of is electro-hydraulic brake system, and another kind is an electromechanical braking system.Electro-hydraulic brake system is meant and utilizes the power source of motor as system, adopts mechanical mechanism to be applied to and realizes movement conversion and reinforcement on the hydraulic oil, finally realizes compressing of brake slipper and brake disc, and then produces required braking force.
In the prior art, the motor of electro-hydraulic brake system all needs customization, has that complex structure, output power are little, the output gain of torque is little and can not satisfy the shortcoming of actual vehicle braking needs.
Summary of the invention
It is a kind of based on motor-driven electric liquid disk-type braking method and device, simple in structure that goal of the invention of the present invention is to provide, and can realize bigger motor ouput force gain.
The present invention is based on same inventive concept, have two independent technique schemes:
1, a kind of based on motor-driven electric liquid disk-type braking method, it is characterized in that: the power of motor output drives the brake piston motion, thereby makes brake slipper compress brake disc behind gear engagement mechanism and fluid drive mechanism two-stage reinforcement, realizes the braking of automobile.
Be provided with nut, screw mechanism between gear engagement mechanism and the fluid drive mechanism, nut, screw mechanism are straight line motion with gear rotation to movement conversion, produce the end thrust that acts on the fluid drive mechanism piston.
Pressure transducer is equipped with at place, the location of screw rod, is used to realize the accurate control of braking.
Be provided with rubber ring between brake piston and the brake cylinder casing, be used for resetting of brake piston.
2, a kind of device of realizing aforementioned based on motor-driven electric liquid disk-type braking method, comprise brake piston, brake slipper, brake disc, brake piston can promote brake slipper and compress brake disc, it is characterized in that: on the motor power output shaft driving gear is housed, driven gear and driving gear engagement; Driven gear and screw rod join, and are provided with the nut that matches with screw rod, and nut connects the piston of fluid drive mechanism, and the motion of fluid drive mechanism piston can drive the brake piston motion.
Pressure transducer is equipped with at the place, location of screw rod.
Be provided with the rubber ring that resets between brake piston and the brake cylinder casing.
The beneficial effect that the present invention has:
Motor ouput force of the present invention realizes the two-stage reinforcement by gear engagement mechanism and fluid drive mechanism, makes to adopt conventional 12V dc brushless motor just can realize the braking ability of electro-hydraulic brake device, and has bigger output power, output torque.
The power gain effect that the present invention is simple and compact for structure, cost is lower, easy realization is bigger greatly reduces the dependence of break to motor performance.And electro-hydraulic brake device of the present invention possesses good versatility, is fit to all medium and small vehicle automobiles, can realize brake-by-wire truly.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
As shown in the figure, braking device comprises brake piston 13, brake slipper 6, brake disc 14, and brake piston can promote brake slipper and compress brake disc, and this is a prior art.
On the pto 4 of 12V dc brushless motor 3 driving gear 1 is housed, driven gear 2 and driving gear 1 engagement, driving gear 1 is 1: 20 with the velocity ratio of driven gear 2; Driven gear 2 joins by spline 5 and screw rod 8, is provided with the nut 9 that matches with screw rod, and nut connects the piston 10 of fluid drive mechanism, and the motion of fluid drive mechanism piston can drive brake piston 13 motions.Pressure transducer 7 is equipped with at the place, location of screw rod, is used for measuring the output braking moment, realizes the accurate control of braking.Be provided with the rubber ring 12 that resets between brake piston 13 and the brake cylinder casing 15, be used for resetting of brake piston.
During braking, dc brushless motor 3 drives driving gear 1 and rotates, and the rotating drive driven gear 2 of driving gear 1 rotates, and realizes the motor deceleration and increases output torque.The moment that increases is applied on the screw rod 7, and then drive nut 8 axially moves along screw rod 7, thereby realize with gear rotation being straight line motion to movement conversion, generation acts on the end thrust of fluid drive mechanism piston 10, makes piston 10 motions, exerts all one's strength by the effect of hydraulic oil 11 and further amplifies, braking impacting force after the amplification is applied on the brake piston 13, brake piston 13 will be braked impacting force and be applied on the brake slipper 6, and last brake slipper 6 compresses brake disc 14, realizes vehicle braked.During brake off, the motor counter-rotation, mechanism moves in the other direction, and under the effect of the rubber ring 12 that resets, brake slipper 6 unclamps with brake disc 14.
Because the present invention has the two-stage boosting mechanism, one-level is the gear engagement structure, and one-level is a fluid drive mechanism, thus have very large reinforcement effect, thus reduce requirement to direct current generator driving moment, driving power.
