Furthermore, the braking system has good universality and is suitable for all automobile types in princ iple, in particular for automobiles using new energy, thus being capable of realizing pure electric automobiles in the true sense.
Description
Technical field
The present invention relates to a kind of brake system of car, be specifically related to a kind of based on motor-driven brake system of car.
Background technology
At present, both at home and abroad most automobile-used brake system also is based on the fluid control mechanical pressure and reaches the braking purpose.In known technology, have with the akin technologic material of the technology of the present invention effect: " linear braking type " brake system (CN101039826), disclosed under linear working state as it, produce the braking displacement by the foot pressure simulator, and obtain exporting brake torque by the processing of respective electronic control unit.We can realize that speed-slackening signal is by the embedded controller collection and make respective handling by this technology.But be defectives such as traditional hydraulic braking or above-mentioned technology all exist complex structure, inconvenience is installed, costs an arm and a leg, fault can not be monitored in real time, more can not find and anyly how to break away from the hint that the traditional braking mode reaches braking effect at controlled signal about mechanical device.The present invention is just for considering automobile brake real-time, safety and industrialization economy, and the research of a kind of brake system of car of doing, the design of the mechanical driving part of giving prominence to the key points.
Summary of the invention
Purpose of the present invention promptly replaces traditional hydraulic braking control setup, and the moment of torsion that the motor that drives based on embedded control system produces can be converted into automobile braking force by actv. by this brake system, thereby reaches the purpose of deceleration and Parking.The present invention goes back emphasis and considers that motor rotation blockage, motor damage, and safety precautionss such as mechanical self-latching have improved the safety factor of brake system.
Based on this, the invention provides a kind of brake system of car, comprise mechanical transmission mechanism and brake push rod group mechanism, mechanical transmission mechanism comprises at least one drive motor, at least one screw mandrel and push rod gear, at least one drive motor is captiveed joint with at least one screw mandrel respectively, each screw mandrel and the interlock of push rod gear; Brake push rod group mechanism comprises brake push rod, down brake push rod, isolator between the brake push rod and set of rollers up and down; The push rod gear is captiveed joint with last brake push rod.
Drive motor and screw mandrel respectively are two, and mechanical transmission mechanism also comprises two gears, and they are separately fixed on two screw mandrels and interlock mutually.
The opposite face of the upper and lower brake push rod of brake push rod group mechanism is all to be curved surface.Isolator and described set of rollers are accepted from the described upward power of brake push rod, and can be that curved surface slides along the opposite face of upper and lower brake push rod.
The present invention is based on the motor-driven of embedded control system, can conveniently gather various valuable signals, and software is realized control, and is portable strong.The emphasis of invention is the design of mechanics transmission device, its simple structure, broken away from traditional fluid control, principle is understandable, especially increased the mechanical self-latching function, (software set) meeting automation self-locking when promptly the propulsive effort of two motor generations makes the brake push rod group be pushed forward to certain position through mechanical transmission mechanism, and in time carry out motor and reverse, eliminate or alleviate pressure on the push rod group, this is to gather the motor signal and by software set, work as mechanical release through embedded system, if speed-slackening signal still exists, then the motor main story and so forth, has been avoided seized phenomenon; And in two motors, there is a motor to break down and to work, another motor is adjusted rotating speed so, through mechanical transmission mechanism the brake push rod group is pushed ahead, reach the braking purpose, in this simultaneously, control system can be from the motor speed acquired signal, and obtains motor running condition, the prompting car owner, thus safety strengthened.Because its simple structure uses accessory few, thereby also embodied the economy of system.Because this system simple in structure, in installation and maintenance, embodied the convenience of operation in addition.This brake system possesses good commonality, is fit to all vehicles, particularly new-energy automobile in principle, can realize pure power vehicle truly.
Description of drawings
Fig. 1 is a brake system structure scheme drawing of the present invention;
Fig. 2 is the curved surface scheme drawing of the upper and lower brake push rod opposite face of brake system of the present invention.
The specific embodiment
The present invention goes back emphasis and considers that motor rotation blockage, motor damage, and safety precautionss such as mechanical self-latching have improved the safety factor of brake system.This brake system comprises following mechanism:
Embedded control system is made up of hardware and corresponding software.
Gear 5 and gear 6 are separately fixed at again on screw mandrel 3 and the screw mandrel 4 and interlock mutually, wherein screw mandrel 3 and screw mandrel 4 again before and after common interlock push rod gear 7.When motor 1 and 2 rotated, screw mandrel 3 and the 4 common push rod gears 7 that drive rotated, because the relative position of screw mandrel 3 and 4 is constant, so can make the rotation (during the motor counter-rotating push rod gear 7 to opposite spin) of push rod gear 7.Drive motor 1 and 2, screw mandrel 3 and 4, gear 5 and 6 and push rod gear 7 formed the mechanical transmission mechanism of brake system jointly.
Last brake push rod 8 and following brake push rod 9 and the isolator between the two 10 and set of rollers 11 (three) have been formed the brake push rod group mechanism of brake system, and push rod gear 7 is captiveed joint with last brake push rod 8.The opposite face of wherein going up brake push rod 8 and following brake push rod 9 is through curved design, shown in the mark in the accompanying drawing 2 13, isolator and set of rollers accept from the thrust of brake push rod 8 can be that curved surface slides along the opposite face of upper and lower brake push rod, thereby reduce the two gap, structure such as accompanying drawing 2 finally reach the purpose to braking brake block 12 pressure boosts.
