The invention has the technical scheme that power output by the motor drives a braking piston to move after boosted by two stages of a gear engaging mechanism and a boosting lever, so that a braking block tightly presses a braking disc to brake automobiles.
Description
Technical field
The present invention relates to a kind of based on motor-driven automobile disk-type braking method and device.
Background technology
At present, the brake system that adopts of domestic and international most of automobile also is based on the fluid control mechanical pressure and reaches the braking purpose.Since the conventional hydraulic drg exist complex structure, parts many, take up space, arrange shortcomings such as inconvenience and system extension be relatively poor.At present a lot of vehicle electronics supplies commercial city is at the research and development mechanical type brake system electric, and English is also referred to as BBW (brake-by-wire).The electronic mechanical braking technology is meant utilizes the propulsion source of motor as system, adopts the mechanism of pure machinery to realize movement conversion and reinforcement, finally realizes compressing of slipper and brake disc, and then produces required braking force.
With the maximally related prior art of the present invention be the disc type electric energy drg of Siemens Company and the disc type electric energy drg of continent TEVES company, but the motor of aforementioned drg needs customization, shortcoming such as have complex structure, cost an arm and a leg.
Summary of the invention
It is a kind of based on motor-driven automobile 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 power output gain.
The present invention is based on same inventive concept, have two independent technique schemes:
1, a kind of based on motor-driven automobile disk-type braking method, it is characterized in that: the power of motor output drives the brake piston motion, thereby makes slipper compress brake disc behind gear engagement mechanism and boosting lever two-stage reinforcement, realizes the braking of automobile.
Be provided with nut, screw mechanism between gear engagement mechanism and the boosting lever, nut, screw mechanism are straight-line motion with gear rotation to movement conversion, produce the axial thrust that acts on boosting lever.
Boosting lever drives the brake piston motion by drive socket.
Pressure sensor is equipped with in the brake piston inboard, is used to realize the accuracy control of braking.
Be provided with rubber ring between brake piston and the brake cylinder casing, be used for the return of brake piston.
2, a kind of device of realizing aforementioned based on motor-driven automobile disk-type braking method, comprise brake piston, slipper, brake disc, brake piston can promote 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 end of boosting lever, and boosting lever can drive the brake piston motion.
Be provided with drive socket between boosting lever and the brake piston, boosting lever drives the brake piston motion by drive socket.
Pressure sensor is equipped with in the brake piston inboard.
Be provided with the return rubber ring between brake piston and the brake cylinder casing.
The beneficial effect that the present invention has:
Motor power output of the present invention realizes the two-stage reinforcement by gear engagement mechanism and boosting lever, makes to adopt conventional 12V dc brushless motor just can realize the deceleration and stopping performance of disc type electronic brake, and has bigger horsepower output, 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 plate disc brake to motor performance.And disc type electronic brake of the present invention possesses good commonality, 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.
The specific embodiment
As shown in the figure, drg comprises brake piston 14, slipper 6, brake disc 15, and brake piston 14 can promote slipper 6 and compress brake disc 15, and this is a prior art.
On the power take-off shaft 4 of 12V dc brushless motor 3 driving gear 1 is housed, driven gear 2 is 1: 40 with driving gear engagement, driving gear 1 with the transmitting ratio of driven gear 2; Driven gear 2 joins by spline 5 and screw rod 7, be provided with the nut 8 that matches with screw rod, nut 8 connects the end of boosting lever 9, is provided with drive socket 10 between boosting lever 9 and the brake piston 14, and boosting lever 9 drives brake piston 14 motions by drive socket 10.Pressure sensor 12 is equipped with in the brake piston inboard, is used for measuring the output lock torque, realizes the accuracy control of braking.Be provided with return rubber ring 13 between brake piston 14 and the brake cylinder casing 11, be used for the return of brake piston.
Glancing impact, 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 realizes with gear rotation being straight-line motion to movement conversion, produces the axial thrust that acts on boosting lever 9.Boosting lever 9 further increases power, acts on brake piston 14 by drive socket 10, will brake thrust at last and be applied on the slipper 6, thereby realize vehicle braked.During brake off, the motor counter-rotation, mechanism's reversing sense motion, under the effect of return rubber ring 13, slipper 6 unclamps with brake disc 15.
Because the present invention has the two-stage force-increasing mechanism, one-level is the gear mesh structure, and one-level is a boosting lever, thus have very large reinforcement effect, thus reduce requirement to DC machine drive torque, driving power.
