Be padded with push rod gap, hinder push rod to advance, only produced compared with low thrust pretension hydraulic system by spring, this process it is main by
Motor carries out regenerative braking, and electromagnetic booster produces brake feel on brake pedal；After gap is padded, electromagnetism is helped
Power device increases push rod thrust, and assistant ejector pin promotes master cylinder valve element hydrodynamic force for brake wheel.
The present invention is achieved by the following technical solutions：
A kind of coil magnet steel combines electromagnetism booster brake, includes master cylinder on rear side of electromagnetic booster and its preceding
The brake pedal in portion, it is characterised in that：The brake pedal promotes connected push rod to advance, the other end position of the push rod
It is used to promote magnet steel in the magnet steel of electromagnetic booster, produces magnetic field to pass through magnet steel after the coil electricity in the electromagnetic booster
Axial thrust on control push rod, the axial thrust of the push rod after electromagnetic booster increase and decrease by promoting magnet steel, the magnet steel
Push rod, the push rod is promoted to promote master cylinder valve core movement, master cylinder to produce the hydraulic coupling rotated for brake wheel.
Described coil can produce the opposite magnetic field of both direction, and the magnetic field is for hindering or promoting magnet steel to move.
Gap or very close to each other can be provided between described magnet steel and push rod, be used between push rod and magnet steel when having gap
Spring is connected, and the magnet steel promotes push rod after gap is filled up.
Described electromagnetism booster brake has one or more pairs of coils and magnet steel combination to constitute.
Described pedal promotes pushrod movement, and push rod promotes magnet steel motion, magnet steel not yet move to fill up with push rod it
Between gap during, coil produce one with the rightabout magnetic field in magnet steel magnetic field, hinder magnet steel motion.
Described magnet steel motion is filled up during gap, push the spring, and spring promotes push rod, push rod to promote master cylinder valve element,
Master cylinder produces a less hydraulic coupling for pretension hydraulic braking system.
After described magnet steel moves to the gap filled up between push rod, coil produces one with magnet steel magnetic field equidirectional
Magnetic field, promote magnet steel motion, promote push rod, push rod promote master cylinder valve element hydrodynamic force.
It is an advantage of the invention that：
1) combined with coil magnet steel, space is small, it is easy to arrange.
2) coil produces magnetic responsiveness quick, without being constantly in holding state consumed energy.
3) there may be gap between magnet steel and push rod, this segment distance before gap is padded can be used for motor and return
Feedback braking.
4) there may be a spring between magnet steel and push rod, during magnet steel fills up gap, spring is applied to push rod
A hydraulic pressure pwc clamp force is produced in master cylinder compared with low thrust, once gap is filled up, hydraulic braking system can immediately put into braking
Work.
5) electromagnetic booster uses power supply, and electric energy is transmitted using electric wire, and relative vacuum booster is vacuumized using pipeline, side
Just arrange and reliability is higher.
6) active brake can be carried out, the active brake function in being driven for intelligence auxiliary.
