In the specific use process, the case where motor works normally:
In the case where driver's brake pedal 2, when driver's brake pedal 2, brake pedal 2 passes through bolt
Connecting rod 3 is driven to move, connecting rod 3 drives connector 5 to move by bolt, and connector 5 is connect by screw thread with first piston, connects
The movement that connecting rod transmits is transmitted to first piston 8 by connector afterwards, and first piston 8 does water by the cooperation with 7 circular hole of bottom plate
Flat line movement.First piston 8 is by the annular opening contacts of the limiting device of bar portion and bottom plate 7, when realizing brake pedal
Limit purpose.First piston 8 moves the area compression so that the first working chamber.In the compression process of the first working chamber volume
In, first piston 8 squeezes the liquid in the first working chamber to the second working chamber by compressing hole.Change the area of compressing hole just
Damping when braking can be changed, the size of compressing hole is mainly by the opposite position of 17 inner hole of circulation hole control valve 12 and cylinder body
Set decision.Angular signal is changed into electric signal by brake pedal rotary angle transmitter 1, and motor position sensor 15 acquires motor 16
Angular signal, two signals are transmitted in ECU (electronic control unit) simultaneously, and ECU (electronic control unit) is by calculating, output
It controls signal and arrives motor 16, motor 16 drives the rotation of pinion gear 21 by key A22, and pinion gear 21 with gear wheel 19 by engaging
It transmits motion on gear wheel 19, gear wheel 19 is transmitted motion on circulation hole control valve 12 by key B20, gear wheel
21 last drive circulation hole control valves 12 rotate, it is possible thereby to change the size of compressing hole.When brake pedal 2 is at small turn
In the case where angle and low velocity, the angular position of the control circulation hole control valve 12 of motor 16, so that compressing hole is in biggish
Circulation area, therefore the damping force acted on brake pedal 2 is smaller；When brake pedal 2 is in big corner and high speed
In the case of, the angular position of the control circulation hole control valve 12 of motor 16, so that compressing hole is in lesser circulation area, because
This, the damping force acted on brake pedal 2 is bigger.After liquid enters the second working chamber, the movement of second piston 13 will push,
So that second piston spring 14 compresses, the internal pressure of the second working chamber increases.The pressure increase of second working chamber also can
So that the pressure in the first working chamber improves, increase the hydraulic counter force acted on brake pedal 2；
Driver loosen the brake 2 in the case where:
Brake pedal return spring 6 pushes connector 5 to move, and one side connector 5 is moved by bolt pusher connecting rod 3,
Connecting rod 3 moves brake pedal 2 counterclockwise by bolt, so that brake pedal 2 returns to original position；Another party
Face, connector 5 are connect by screw thread with first piston 8, and the drawback movement of connector 5 makes first piston 8 also carry out backhaul fortune
Dynamic, to when retracting, the area of the first working chamber increases first piston 8, and liquid is flow back into from the second working chamber by check valve 10
In first working chamber.During liquid flowing, due to the effect of second piston spring 14, so that the pressure in the second working chamber
Power is bigger than the first working chamber, and the liquid in the second working chamber will push the pretightning force of one-way valve spring 14, to open check valve
10, so that liquid is flowed to the first working chamber from the second working chamber, 10 hole of check valve is done greatly as far as possible, so that the process of liquid reflux
As far as possible quickly, to guarantee the reliability braked next time.Meanwhile angular signal is changed by brake pedal rotary angle transmitter 1
Electric signal, motor position sensor 15 acquire the angular signal of motor 16, and two signals are transmitted to ECU simultaneously, and (electronic control is single
Member) in, ECU (electronic control unit) outputs a control signal to motor 16, motor 16 drives small tooth by key A22 by calculating
21 rotation of wheel, for pinion gear 21 by transmitting motion on gear wheel 19 with engaging for gear wheel 19, gear wheel 19 passes through key B20
It transmits motion on circulation hole control valve 12, gear wheel 21 finally drives circulation hole control valve 12 to rotate, so that circulation
Porosity controlling valve 12 is restored to corresponding position；
The case where motor failure:
In the case where driver's brake pedal 2, when driver's brake pedal 2, brake pedal 2 passes through bolt
Connecting rod 3 is driven to move, connecting rod 3 drives connector 5 to move by bolt, and connector 5 is connect by screw thread with first piston, connects
The movement that connecting rod transmits is transmitted to first piston 8 by connector afterwards, and first piston 8 does water by the cooperation with 7 circular hole of bottom plate
Flat line movement.First piston 8 is by the annular opening contacts of the limiting device of bar portion and bottom plate 7, when realizing brake pedal 2
Limit purpose.First piston 8 moves the area compression so that the first working chamber.In the compression process of the first working chamber volume
In, first piston 8 squeezes the liquid in the first working chamber to the second working chamber by compressing hole.When motor 16 fails, motor
Return spring 25 will drive the state that circulation 12 opposing cylinder 17 of hole control valve turns to maximum opening, it is ensured that compressing hole can
Smooth circulating liquid.After liquid is squeezed into the second working chamber by compressed first working chamber, the movement of second piston 13 will push, from
And second piston spring 14 is compressed, the internal pressure of the second working chamber increases, and the pressure of the second working chamber can make after increasing
The pressure obtained in the first working chamber improves, and increases the hydraulic counter force acted on brake pedal 2, thus when ensure that motor failure
The safety of braking.
Although hereinbefore having been made with reference to some embodiments, present invention is described, of the invention not departing from
In the case where range, various improvement can be carried out to it and can be with equivalent without replacement component therein.Especially, as long as not
There are structural conflict, the various features in presently disclosed each embodiment can be combined with each other by any way
It uses, the description for not carrying out exhaustion to the case where these combinations in the present specification is only to be in omit length and economize on resources
The considerations of.Therefore, the invention is not limited to specific embodiments disclosed herein, and including falling within the scope of the appended claims
