It is contracted by minute-pressure, telescopic rod spring is compressed, and ensure that there are larger pressure between brake block and brake disc.Rubbing in power mechanism
It wipes wheel to contact with brake disc extruding, friction pulley drives arc guide block slightly to move in arc-shaped guide rail through third shaft, the second plate
Spring is slightly compressed；Brake disc drives friction wheel from rotation, and setting the direction of rotation of friction pulley at this time is counterclockwise, friction pulley drive
The rotation of third shaft, third shaft drive the rotation of the 4th gear, and the 4th gear is rotated through third gear band dynamic bevel gear, bevel gear
Second gear rotation is driven through the second shaft, the combination of cone tooth and first rotating shaft, second gear is to rotate clockwise at this time；Second tooth
Wheel drives first gear to start to rotate counterclockwise, and still set first gear at this time rotates to be rotating forward.It is rotated forward in first gear
When, first gear drives the first flexible interior bar to rotate forward through lead key, and then the first flexible housing rotates forward, and scroll spring is compressed；?
During first flexible interior bar rotates forward, match since screwed ring covers upper internal screw thread with the external screw thread phase screw thread in the first flexible interior bar
It closes, the first flexible interior bar is axially mobile to the direction of brake block, and two lead keys are gradually from the keyway of first gear
It is detached from.During the first flexible interior bar is axially mobile to the direction of brake block, the promotion of the first flexible interior bar
So that the distance between third fixed plate and the 4th fixed plate reduce, and then the second telescopic rod and the continuation of telescopic rod spring are pressed
Contracting, the 4th fixed plate are gradually increased to the pressure of brake block, and the pressure between brake block and brake disc is gradually increased, so that
Friction effect between brake block and brake disc is gradually increased.After two lead keys are detached from from the keyway of first gear, first
Gear no longer will drive the first flexible interior bar to rotate forward through lead key, and then entire first telescopic rod no longer rotates forward, and first is flexible at this time
The promotion of interior bar is so that the distance between third fixed plate and the 4th fixed plate reach minimum, the second telescopic rod and telescopic rod spring
It is compressed to the limit, the 4th fixed plate reaches maximum to the pressure of brake block, and the pressure between brake block and brake disc reaches most
Greatly, so that the friction effect between brake block and brake disc reaches maximum.
During first gear drives second gear to rotate forward, second gear is moved with carry-over bar to the direction of arc panel
Dynamic, until second gear persistently stirs the end of rack gear, rack gear moves flexible direction of the housing to arc panel of square type through L-type strip
Mobile, the first leaf spring is compressed, and arc panel increases the pressure of one-way clutch ring at this time, and arc panel generates limit to one-way clutch ring
Position effect, in this way under the action of one-way clutch ring, the first flexible housing will not generate reversion, and then compressed scroll spring
It will not discharge；That is, in first gear no longer after lead key drives the first flexible interior bar to rotate forward, the first flexible interior bar and the
One flexible housing no longer rotates and the first telescopic rod is maintained the statusquo, the interior spiral shell of the external screw thread in the first flexible interior bar and screw thread ring set
Be spun on and be threadedly engaged down self-locking, ensure that the distance between third fixed plate and the 4th fixed plate maintain minimum, brake block with
Maintain maximum friction effect between brake disc.
After driver no longer brakes, the hydraulic system on automobile makes hydraulic column is mobile to reset, and hydraulic column drives first
Fixed plate is mobile to the direction far from brake disc, and then the second fixed plate, power mechanism and pressure exerting arrangement are to far from brake disc
Direction is mobile.Friction pulley in power mechanism is detached to be engaged with brake disc, and the brake block in pressure exerting arrangement is detached from and brake
The frictional fit of hull.After brake block is detached from the frictional fit with brake disc, under the reset response of telescopic rod spring, second
Telescopic rod is restored to nature.It being detached from friction pulley with after being engaged of brake disc, second gear no longer obtains power,
Under the reset response of first leaf spring, square type stretches housing to the mobile reset in the direction far from arc panel, until the first leaf spring restores
To nature, arc panel is zero to the pressure of one-way clutch ring at this time, and arc panel will not generate limit to one-way clutch ring and make
With then compressed scroll spring discharges, the first flexible housing drives the reversion of one-way clutch ring, the first flexible interior bar reversion.
It is mutually threadedly engaged since screwed ring covers upper internal screw thread with the external screw thread in the first flexible interior bar, then anti-in the first flexible interior bar
During turning, the first flexible interior bar drives lead key axially mobile to the direction of the first flexible housing, and first is flexible interior
Lead key on bar can be re-introduced into the corresponding keyway of first gear, until lead key is restored to home position.When there is lead key
When cannot be introduced into without the alignment corresponding keyway of first gear completely, due to making the flexible housing of square type mobile in the first leaf spring
It resets, square type stretches housing through the mobile reset of L-type strip carry-over bar, and then rack drives second gear inverts, second gear band
Dynamic first gear reversion；That is, lead key it is mobile reset be inserted into first gear corresponding keyway when, second gear is anti-
Turn；When lead key cannot be introduced into without the alignment corresponding keyway of first gear completely, in second gear reversion process, it may appear that
The case where lead key is aligned completely with the corresponding keyway of first gear, lead key just can move reset to be inserted into first gear corresponding at this time
Keyway in.Finally, the first telescopic rod no longer rotates, and lead key is restored to home position after the release of scroll spring.
For Quick brake mechanism of the invention, in driver's normal braking, in brake block and brake disc friction brake
When, the distance between third fixed plate and the 4th fixed plate are gradually reduced and until extreme positions, and the 4th fixed plate is to brake block
Pressure be gradually increased and until maximum, braking effect of such brake block during brake can be gradually increased, Zhi Daoda
To maximum braking effect.That is, it is compared to traditional brake during driver's normal braking, the present invention
Quick brake mechanism brake disc can be braked faster, stop automobile quickly.
Movement when driver needs to bring to a halt because of fortuitous event, when can be than normal braking when driver brings to a halt
Larger, brake block and brake when brake block and the pressure ratio normal braking of brake disc phase CONTACT WITH FRICTION when bringing to a halt in this way
The pressure of disk phase CONTACT WITH FRICTION is big；The pressure of brake disc extrusion friction wheel also than normal braking when it is big, friction pulley through third turn
Axis drives the larger movement in arc-shaped guide rail of arc guide block, and the second leaf spring is by larger compression.When for normal braking, friction pulley warp
After third shaft drives arc guide block slightly to move in arc-shaped guide rail, the diameter that friction pulley is in contact with brake disc is D1；It is right
When bringing to a halt, friction pulley drives arc guide block in arc-shaped guide rail after larger movement through third shaft, friction pulley and brake disc
The diameter being in contact is D2；D2 is greater than D1, then brake disc drives the speed of friction wheel from rotation to be greater than normal braking when bringing to a halt
When brake disc drive friction wheel from rotation speed；That is, more quicker, the second gear that power mechanism acts when bringing to a halt
Drive the speed of first gear rotation more quicker, the first flexible interior bar reaches distance between third fixed plate and the 4th fixed plate
Time when to minimum can be more shorter, and the time that brake block reaches maximum braking effect can be more shorter, and final brake block can be more
Fast brakes brake disc, stops automobile quickly.Be compared to it is traditional bring to a halt, the present invention in it is quick
Braking mechanism can shorten the braking time brought to a halt in conventional brake mechanism, can quickly stop after automobile encounters emergency case
Only, it reduces driver's automobile after encountering emergency case and suddenly touching on the brake and touches a possibility that unexpected, more protect driving
The safety of person.
When driver carries out the brake of different dynamics because of different situations, the same energy of Quick brake mechanism of the invention
Faster some brakes；Due to being touching on the brake for driver's difference dynamics, then brake disc to the extruding force of friction pulley not yet
Together, and then friction pulley and the diameter of brake disc phase friction point are also different, and such design avoids friction pulley and continues and brake
Disk avoids brake disc and is rubbed at same diameter when institute for a long time the case where the friction point of same diameter mutually rubs
Caused by damage, extend brake disc use the time, reduce the frequency of maintenance and the replacement of brake disc.
Relative to traditional brake technique, the friction pulley of Quick brake mechanism of the invention in brake, in power mechanism
With brake disc phase frictional fit, power mechanism is enabled to provide power to pressure exerting arrangement, and then shortens third fixed plate and the 4th
The distance between fixed plate increases the 4th fixed plate to the pressure of brake block, achievees the purpose that increase braking effect.It is bringing to a halt
When, Quick brake mechanism can shorten the braking time brought to a halt in conventional brake mechanism, the energy after automobile encounters emergency case
Quickly stop, reducing driver's automobile after encountering emergency case and suddenly touching on the brake and touch a possibility that unexpected, more protect
The safety of driver is protected.In addition, friction pulley and the diameter of brake disc phase friction point are also different when different dynamics touch on the brake,
And then damage caused when brake disc is rubbed at same diameter for a long time is avoided, extend brake disc and use the time, subtracts
The small frequency of maintenance and the replacement of brake disc.The configuration of the present invention is simple has preferable using effect.
