Dynamic cylinder 50, pressure-reducing valve 60 form.Liquor storage device 10 and the artificial brake operating element such as annexation of brake pedal 11 with it is existing
Technology is identical, and wheel brake cylinder 50 is communicated by Stress control cylinder 20, pressure-reducing valve 60 with liquor storage device 10 respectively, liquor storage device 10
In working fluid is housed, the flow direction of working fluid enters car to be flowed out from liquor storage device 10, by Stress control dress cylinder 20
Take turns checking cylinder 50, then by wheel brake cylinder 50 via decompression regulating device be that pressure-reducing valve 60 flows back to liquor storage device 10.
Stress control cylinder 20 includes cylinder body 21 and a piston 22, and piston 22 is liquid-tight by the first bilateral sealing device 221
Ground is simultaneously slidably received within cylinder body 21.Cylinder body 21 is divided into the first chamber 211 and the second chamber 212 by piston 22, and first is two-way
Sealing device 221 maintains the first chamber 211 and the second chamber 212 is separate.First bilateral sealing device 221 can be O-ring
Or a pair of opposite leather cups, although can be mounted on cylinder body 21 in the groove made, can also be installed on piston 22
In the groove made.
Inlet 41 and liquid outlet 42 are provided with first chamber 211, inlet 43 and liquid outlet are provided with the second chamber 212
44.Inlet 41,43 communicates with liquor storage device 10, and liquid outlet 42,44 communicates with wheel brake cylinder 50.Inlet 41,43 with
In the stream of liquor storage device, and liquid outlet 42,44 in the stream of wheel brake cylinder 50 with being each provided with a check valve 31-
34 so that working fluid can only flow to wheel brake cylinder 50 from liquor storage device 10, and be unable to reverse flow.Piston 22 passes through screw thread
Transmission mechanism such as screw mandrel 23 are axially moved under the driving of motor 25, and motor can forward and reverse direction rotation.Set on screw mandrel 23 limited
The round platform 231 that throwing bar 23 is axially moved, round platform 231 push up the outside for being located at motor 25.Further, screw mandrel 23 can be motor
25 output shaft, further, the advance of piston 22 and retract that to depend on motor 25 be to rotate forward or rotating backward.
The course of work of the Vehicular brake device is explained below.When Vehicular brake device is in normal condition, in car
The control for taking turns working fluid pressure (being hereafter referred to as " brake pressure ") in checking cylinder 50 is by being controlled, entering to motor 25
And control pressure master cylinder 20 is realized.
With pushing for brake pedal 11, triggering motor 25 drives screw mandrel 23 to rotate.When motor 25 rotates forward, screw mandrel 23
Piston 22 is promoted to be moved to the first chamber 211, now the first chamber 211 is working chamber, and intracavitary is full of working fluid.With working fluid
Pressure rise, check valve 32 are opened, and working fluid is pumped into checking cylinder 50 from Stress control cylinder 20, and front wheel brake cylinder is with after
Taking turns checking cylinder is promoted with identical Fluid pressure；At the same time, the second chamber 212 is fluid-infusing chamber, with piston 22 to first
Chamber 211 is moved, and negative pressure is produced in the second chamber 212, and check valve 33 is opened, and working fluid is flowed into second from liquor storage device 10
In chamber 212.When piston 22 is advanced to the bottom of the first chamber 211, motor control assembly controlled motor 25 rotates backward, and now
One chamber 211 is fluid-infusing chamber, and the second chamber 212 is working chamber, and check valve 34 is opened, and working fluid flows out from the second chamber 212, simultaneously
Check valve 31 is opened, and working fluid is flowed into from liquor storage device 10 in first chamber 211.Working fluid is from Stress control cylinder 20
After outflow, as known in the art, working fluid is flowed into wheel brake cylinder 50, the braking pressure in wheel brake cylinder 50
Power increases so that brake component acts on front and back wheel, completes brake.Piston 22 runs to the second chamber from the bottom of the first chamber 211
The working fluid discharged during 212 bottom carries out 10-15 braking enough, and motor 25 need not rotate backward progress during this period
Reset, so as to save electric energy, the response speed of Stress control dress cylinder 20 when repeatedly continuous braking also greatly improved.
Between the downstream position of wheel brake cylinder 50 and liquor storage device 10, a pressure-reducing valve 60 is provided with, when release is made
During dynamic pedal 11, if wheel brake cylinder 50 is in on-position, working fluid just passes through pressure-reducing valve 60 from wheel brake cylinder 50
It is back in liquor storage device 10, so as to discharge brake component.
Embodiment 2：In embodiment 1, because working chamber is in high pressure conditions, there is opposition to piston 22, when
, can be by being continuously applied certain driving torque to motor 25 to prevent the retraction of piston 25 when system is in pressure holding pattern
Motion.But such arrangement will disadvantageously result in the increase of power consumption.
For disadvantages mentioned above, the present embodiment is arranged to：Thread transmission be the two-way lead angle of screw mandrel 23 it is small in
Equivalent friction angle, so as to form a bidirectional self-locking structure.When discharging brake pedal 11, motor 25 stops operating, due to spiral shell
Line lift angle is small self to be locked on screw mandrel 23 in equivalent friction angle, piston 22, maintains the Fluid pressure in working chamber, so as to
Save electric energy.
Embodiment 3：Because the drive connection between the output shaft and piston 22 of motor 25 is to be passed by the screw thread on screw mandrel 23
Dynamic, when screw mandrel 23 rotate, presence can cause the force of sliding friction of the generation circumferential movement of piston 22 between screw thread, and this circumference
Motion is unnecessary, and existing arrangement will cause the increase for causing power consumption, be will also result under 22 liquid-tight effect of piston
Drop.
For disadvantages mentioned above, the present embodiment is arranged to：One position-limit mechanism is set, for example opens up an endoporus on the piston 22
220, a gag lever post 24 is accommodated through endoporus 220, gag lever post 24 is axially parallel fixed on the two of cylinder body 21 with piston 22
Between the end cap of end.Gag lever post 24 in liquid-tight manner and is slidably fitted within endoporus 220 by the second sealing device 222, and second is close
Seal apparatus 222 can be O-ring or rubber cup.In addition, position-limit mechanism can also be the groove made on cylinder body 21 and work
Made on the groove and middle cylinder body 21 made in the projection or piston 22 with groove fluid-tight engagement made on plug 22
With the projection of groove fluid-tight engagement (diagram does not show).
When piston 22 moves in cylinder body 21, position-limit mechanism ensure that piston 22 is not sent out during promoting and retracting
Raw circumferential movement, further saves the consumption of electric energy.
Furthermore, it is necessary to illustrate, the specific embodiment described in this specification, the shape of its parts and components, it is named
Title etc. can be different.The equivalent or simple change that all construction, feature and principles according to described in inventional idea of the present invention are done, is wrapped
Include in the protection domain of patent of the present invention.Those skilled in the art can be to described specific implementation
Example is made various modifications or supplement or substituted using similar mode, structure without departing from the present invention or surmounts this
Scope as defined in the claims, protection scope of the present invention all should be belonged to.
