Detailed description of the invention
Actively valve pocket 5 is located in the endoporus 101 of valve body 1 and is in initial position normally, drive spring 4 is located at actively between valve pocket and valve body, at this initial position, actively valve pocket 5 and rubber valve parts 6 axial contact seal, actively valve pocket 5 side is had step-like through hole by its inner step hole step 502 by air valve base 8 axial limiting, opposite side, traverses the 202 of active clip 2 of valve body and is close to the big platform sidewall 503 of the actively step-like through hole of valve pocket 5；Actively clip 2 is inserted in a cross-drilled hole of valve body, two skirt grooves 203 of this active clip 2 are blocked by the card base 301 of collar 3, this collar 3 is positioned at valve body 1 cylindrical groove, make the trend of actively two oriented contract of the skirt of clip 2, air valve base 8 realizes the axial location with valve body 1 by locking plate 9, and air valve base 8 and rubber valve parts 6 exist gap 10。
A kind of embodiment of the present utility model is also to include a sealing ring 7, is embedded in the circular groove of air valve base 8, outer lip and the actively big endoporus hole wall fitted seal of valve pocket 5。
A kind of embodiment of the present utility model is, the air valve base inverted cone surface 801 of described air valve base 8 contacts with lateral edges 201 in actively two skirts of clip。
A kind of embodiment of the present utility model is that the seal band opposite site of described active valve pocket 5 and rubber valve parts 6 has arc-shaped seal surface。
A kind of embodiment of the present utility model is that the sealing seamed edge opposite site of described air valve base 8 and rubber valve parts 6 has arc-shaped seal surface。
This utility model is further illustrated below in conjunction with accompanying drawing and conventional vacuum booster of the prior art。
In order to contrast, Fig. 1 illustrates the sectional structure of a kind of conventional vacuum booster, and as shown in Figure 1, vacuum booster includes negative pressure cavity 11 and atmosphere chamber 14, and centre is separated by boosting disk 13 and diaphragm 12；The right side control part of vacuum booster includes air valve port and vacuum valve port,。Vacuum valve port is used for controlling whether negative pressure cavity 11 connects with atmosphere chamber 14, air valve port is used for controlling whether air is allowed to enter atmosphere chamber 14, it is under inoperative situation at booster, vacuum valve port is opened, air valve port is closed, now negative pressure cavity 11 connects with atmosphere chamber 14 and is evacuated, air cannot be introduced into, when brake pedal is operated, vacuum valve port is closed, namely negative pressure cavity 11 and atmosphere chamber 14 are isolated, air valve port is opened, air enters atmosphere chamber 14, so, draught head is there is between negative pressure cavity 11 and atmosphere chamber 14, boosting disk 13 will promote to negative pressure cavity 11 direction, thus producing power-assisted。
Feature of the present utility model is that atmos-valve mouth structure is designed, it is provided that the mechanical type driving mechanism of a kind of pair of atmos-valve shape of the mouth as one speaks formula, makes vacuum booster be provided that bigger power-assisted in emergency situations。The control part for vacuum booster that Fig. 2 represents, first air valve port includes actively valve pocket 5 and rubber valve parts 6, second largest valve port while includes air valve base 8 and rubber valve parts 6, and vacuum valve port includes valve body 1 and rubber valve parts 6, and three shares rubber valve parts 6。
For vacuum valve port, it is closed to be coordinated by actively valve pocket 5 and rubber valve parts 6 and controls。
For air valve port, air valve base 8 and valve rod 30 are riveted together, air valve base shoulder 802 connects with actively valve pocket inner step hole step 502, initial position, actively valve pocket 5 coordinates closedown the first air valve port with rubber valve parts 6, air valve base 8 and rubber valve parts 6 cooperatively form second largest valve port while, are now open modes；Valve rod 30 can be promoted (in figure to the left for promotion state) with pedal force, and air valve base 8 is promoted therewith to the left, now actively valve pocket 5 also with air valve base 8 to left movement；So that the relative valve body 1 of rubber valve parts 6 is moved to the left, closing vacuum valve port, hereafter the relative valve body 1 of rubber valve parts 6 is motionless, but along with active valve pocket 5 continues to left movement, air valve port is opened, and air can pour in vacuum booster atmosphere chamber from right side, forms power-assisted。But, when air pour in formation pressure reduction after can band moving valve 1 and rubber valve parts 6 be moved to the left, namely move to active valve pocket 5, thus reducing air valve port opening, this voluntary straining maneuver causes that air valve port is not easily opened to required aperture at short notice, thus causing that braking time is longer, it is impossible to realize quickly, little input dynamic braking。
In the present embodiment, active valve pocket 5 coordinates, with actively clip 2, the trigger condition determining mechanical type driving mechanism, and this trigger condition depends primarily on pedal force and speed, and namely pedal force and speed obtain product, and this trigger condition can adjust。
When air valve base 8 promotes active valve pocket 5 to when being moved to inspire condition away from the direction controlling valve member, actively clip 2 is under the effect of collar 3 clamping force, actively 2 two skirts of clip are stuck in actively valve pocket step 501 position, actively clip 2 is made active valve pocket 5 to be defined to controlling the effect that valve member direction is spacing, namely trigger position (such as Fig. 3) is formed, at trigger position, air valve base 8 replaces actively valve pocket 5 and rubber valve parts 6 and forms second largest valve port while, so, air valve base 8 has and bigger moves axially space freely, its result is, air valve port is easier to open, large quantity of air pours in booster atmosphere chamber, reach bigger braking auxiliaring effect at short notice。
Such as Fig. 4, when releasing braking, along with the input power of valve rod 30 diminishes, air valve base 8 moves to right, air valve base inverted cone surface 801 contacts with lateral edges 201 in actively two skirts of clip, along with air valve base 8 continues to move to right, actively clip 2 is by spreading, when aperture reaches actively valve pocket big sidewall 503 width of step-like through hole, actively clip 2 position-limiting action is released from, actively valve pocket 5 moves right under the effect of drive spring 4 drag to the right, until vacuum booster is returned to initial position, wherein, locking plate 9 plays the power transmission and the positioning action that make parts in mechanical type driving mechanism finally be returned to initial position。
In sum, the mechanical type driving mechanism that this utility model embodiment proposes can make vacuum booster rapidly be desirable brake force on triggering, provides brake hard for vehicle, and the major part of this mechanism is plastic material, it is possible to reduces cost and total amount。
