Description
本發明是有關於一種煞車裝置，特別是指一種氣壓煞車繼動閥。The invention relates to a brake device, in particular to a pneumatic brake relay valve.
參閱圖1，現有的車輛煞車系統，包括一空壓機11、一由該空壓機11補充高壓氣體的儲氣瓶12、一連接該儲氣瓶12的引導管路13、一連接該引導管路13的繼動閥14、複數連接該繼動閥14的致動件15（圖中僅顯示一個）、一連接該儲氣瓶12的第一煞車管路16、一連接該第一煞車管路16的煞車踏板17，及一連接該煞車踏板17及該繼動閥14的第二煞車管路18。Referring to FIG. 1 , a conventional vehicle brake system includes an air compressor 11 , a gas cylinder 12 supplemented with high pressure gas by the air compressor 11 , a guiding pipeline 13 connected to the gas cylinder 12 , and a connecting guide tube. The relay valve 14 of the road 13, the actuator 15 connected to the relay valve 14 (only one is shown), a first brake line 16 connecting the gas cylinder 12, and a first brake tube The brake pedal 17 of the road 16 and a second brake line 18 connecting the brake pedal 17 and the relay valve 14.
在還沒有進行煞車時，該儲氣瓶12將高壓氣體分別經過該引導管路13及該第一煞車管路16而送達該繼動閥14及該煞車踏板17，由於此時該繼動閥14及該煞車踏板17不會導通，因此高壓氣體無法通過，故該等致動件15不會產生煞車效果。When the brake has not been carried out, the gas cylinder 12 supplies the high pressure gas to the relay valve 14 and the brake pedal 17 through the guide line 13 and the first brake line 16, respectively, because the relay valve at this time 14 and the brake pedal 17 are not turned on, so that the high pressure gas cannot pass, so the actuating members 15 do not produce a braking effect.
而當使用者踩踏該煞車踏板17而使該第一煞車管路16及該第二煞車管路18導通時，使高壓氣體通過該第二煞車管路18並到達該繼動閥14，進而驅使該繼動閥14導通，而使來自該引導管路13的高壓氣體通過並到達該等致動件15，因此產生煞車效果。When the user steps on the brake pedal 17 to turn on the first brake line 16 and the second brake line 18, high pressure gas is passed through the second brake line 18 and reaches the relay valve 14, thereby driving The relay valve 14 is turned on, and the high-pressure gas from the pilot line 13 is passed through and reaches the actuators 15, thereby generating a braking effect.
然而，車體較長的車輛中，例如巴士，為了對後輪也能產生煞車效果，作為觸發使該繼動閥14導通的該第二煞車管路18的長度必須設計非常長，卻導致了氣體壓力的反應時間受到延遲，且透過氣壓的觸發也會有煞車線性度較差的問題，因此會影響煞車效果，而透過氣壓來觸發控制該繼動閥14的一開口(圖未示)的大小以使該引導管路13及該致動件15之間導通時，會需要較多參數同時參與控制，由於參數多而導致不線性，以至於難以精確控制該繼動閥14的該開口的大小，不僅控制上較複雜，且控制精確度也較差，因此有需要對該繼動閥進行改良。However, in a vehicle with a long body, such as a bus, in order to generate a braking effect on the rear wheel, the length of the second brake pipe 18 that is used to trigger the relay valve 14 to be turned on must be designed to be very long, which results in a long The reaction time of the gas pressure is delayed, and the triggering of the gas pressure also has the problem that the linearity of the brake is poor, so that the braking effect is affected, and the size of an opening (not shown) that controls the relay valve 14 is triggered by the air pressure. When the guiding line 13 and the actuating member 15 are turned on, more parameters are required to participate in the control at the same time, which is not linear due to a large number of parameters, so that it is difficult to precisely control the size of the opening of the relay valve 14. Not only is the control more complicated, but the control accuracy is also poor, so there is a need to improve the relay valve.
現有一種繼動閥，如美國專利號碼US7577509所示，是以控制一電磁閥的氣體導通比例來控制一儲氣瓶與一防鎖死煞車系統之間的導通狀態，然而，同樣是以氣體壓力驅動的方式來觸發控制該繼動閥的一開口(圖未示)的大小，因此需要較多參數控制，由於參數多而導致不線性，以至於難以精確控制該繼動閥的該開口的大小，控制上較複雜，且同樣具有煞車線性度差以及精確度差的缺點。A conventional relay valve, as shown in U.S. Patent No. 7,757,509, controls the conduction state between a gas cylinder and an anti-lock brake system by controlling the gas conduction ratio of a solenoid valve, however, it is also a gas pressure. The driving mode triggers the size of an opening (not shown) that controls the relay valve, so more parameter control is required, and the parameter is not linear due to a large number of parameters, so that it is difficult to precisely control the size of the opening of the relay valve. It is more complicated to control, and it also has the disadvantage of poor linearity and poor accuracy.

And a stopper portion 613 extending radially outward and facing the stopper 241, the follower 62 having a pushing portion 621 adjacent to the lower portion of the cam portion 612 to be pushed by the cam portion 612, and a The urging portion 621 extends downwardly into the tube wall 22 and is configured to push against the rod portion 622 of the wearing portion 431 of the moving group 43. The second elastic member 63 is located at the pushed portion 621 and the top connecting wall. The pushing force of the pushing portion 621 is made to be urged away from the top connecting wall 23 by 23.
參閱圖3、4、10，使用時，是以一壓力源91連接於該第一閥口331，並將該等第二閥口332分別連接於二制動室92，再將該壓力源91透過一踏板93及一常開電磁閥94連接該第四閥口212，以及將該壓力源91透過一常閉電磁閥95連接該第五閥口211，當該移動組43位於該非導氣位置時，該等第二閥口332與該第一閥口331不連通，因此該壓力源91無法驅使該等制動室92運作。Referring to Figures 3, 4, and 10, in use, a pressure source 91 is coupled to the first valve port 331, and the second valve ports 332 are respectively coupled to the second brake chamber 92, and the pressure source 91 is transmitted through A pedal 93 and a normally open solenoid valve 94 are coupled to the fourth valve port 212, and the pressure source 91 is coupled to the fifth valve port 211 through a normally closed solenoid valve 95 when the moving group 43 is in the non-conducting position. The second valve ports 332 are not in communication with the first valve port 331, so the pressure source 91 cannot drive the brake chambers 92 to operate.
參閱圖7、9、10，當該踏板93受踩踏而進行煞車時，以一控制單元（圖未示）驅使該馬達部51轉動一預定角度以帶動該蝸桿部52轉動，進而連動該連動件61轉動，並使該止擋部613遠離該擋塊241，該凸輪部612朝下偏轉時即會推抵下方的該從動件62朝下移動，進而推抵該移動組43移動至該導氣位置（見圖9），在正常運作狀況下，此時該洩壓流道45受到封閉，該等第二閥口332與該第一閥口331連通，因此該壓力源91就能驅使該等制動室92運作而連動煞車機構（圖未示）作動，而產生後續的煞車行為。Referring to FIGS. 7, 9, and 10, when the pedal 93 is stepped on to brake, the control unit (not shown) drives the motor portion 51 to rotate by a predetermined angle to drive the worm portion 52 to rotate, thereby interlocking the linkage member. 61 is rotated, and the stopping portion 613 is away from the stopper 241. When the cam portion 612 is deflected downward, the follower 62 that is pushed downward is moved downward, and then the moving group 43 is pushed to the guide. The gas position (see FIG. 9), under normal operating conditions, at which time the pressure relief passage 45 is closed, and the second valve port 332 is in communication with the first valve port 331 so that the pressure source 91 can drive the When the brake chamber 92 is operated and the brake mechanism (not shown) is actuated, subsequent braking behavior is generated.
參閱圖4、7、10，而當不需要煞車時，該踏板93不再受踩踏而使煞車解離，該控制單元驅使該馬達部51反轉該預定角度以連動使該凸輪部612朝上偏轉時，該止擋部613會朝該擋塊241鄰近，該從動件62就會受到該第二彈性件63的推抵而朝上移動，此時該移動組43不再受到外力就能夠回到該非導氣位置，而該洩壓流道45不再受到封閉，剩下的氣體會經由該洩壓流道45而由該第三閥口333流出該氣壓煞車繼動閥外部。Referring to Figures 4, 7, and 10, when the brake is not required, the pedal 93 is no longer stepped on to disengage the brake, and the control unit drives the motor portion 51 to reverse the predetermined angle to interlock the cam portion 612 upward. When the stopper 613 is adjacent to the stopper 241, the follower 62 is pushed upward by the pushing of the second elastic member 63, and the moving group 43 can be returned without being subjected to an external force. To the non-conducting position, the pressure relief passage 45 is no longer closed, and the remaining gas flows out of the pneumatic brake relay valve through the third valve port 333 via the pressure relief passage 45.
由於該移動組43是由該從動件62直接推抵而移動，而該從動件62是由該馬達部51透過該連動件61連動，該蝸桿部52及該蝸輪部611的配合能產生扭力大以及止逆的作用，而能直接透過傳動元件的連動來精確控制該第一彈性件44的壓縮距離，以調整內部氣體流量大小，並確保作動時間之精確，使煞車作動時間縮短，可提升該作用空間34及該導氣空間35之間的通氣氣流大小（即該氣壓煞車繼動閥輸出開口的大小）的精確度、線性度及增快該氣壓煞車繼動閥的作動時間，相較於現有的繼動閥只能以氣壓驅動而有控制煞車線性度及精確度低以及反應作動慢的缺點，本發明明顯能夠改善現有的繼動閥的缺點。另外，在該馬達部51不作動時，該蝸桿部52及該蝸輪部611相互嚙合而固定不動，因此可以避免來自該連動件61下方的外力推動而使該連動件61改變位置，因此具有止逆及節能的效果。Since the moving group 43 is directly moved by the follower 62, and the follower 62 is interlocked by the motor portion 51 through the linking member 61, the cooperation of the worm portion 52 and the worm wheel portion 611 can be generated. The torque is large and the function of the backrest can be directly controlled by the linkage of the transmission elements to precisely control the compression distance of the first elastic member 44, thereby adjusting the internal gas flow rate and ensuring the accuracy of the actuation time, so that the braking time is shortened. Increasing the accuracy and linearity of the ventilation airflow between the working space 34 and the air guiding space 35 (ie, the size of the output of the pneumatic brake relay valve) and increasing the actuation time of the pneumatic brake relay valve Compared with the existing relay valve, which can only be driven by air pressure and has the disadvantages of controlling the linearity and accuracy of the brake and the slow reaction, the present invention can obviously improve the disadvantages of the existing relay valve. Further, when the motor portion 51 is not actuated, the worm portion 52 and the worm wheel portion 611 are meshed with each other and fixed, so that the external force from the lower portion of the interlocking member 61 can be prevented from being pushed and the position of the interlocking member 61 can be changed. Reverse and energy saving effects.
參閱圖7、10、11，另外當該踏板93受踩踏而進行煞車時，該移動組43位於該非導氣位置（見圖4），只要驅使該壓力源91的氣壓通過該常開電磁閥94並進入該第四閥口212後，氣壓就會推抵該膜片54朝下移動，進而使該推抵部542朝下推抵使該移動組43移動至該導氣位置；當該踏板93不再受踩踏而煞車解離時，將該第四閥口212的氣壓洩除後，該膜片54即會受到下方的氣體的推抵而回到原始位置，該移動組43也會受到該第一彈性件44的彈力而朝上移動，使該移動組43移動至該非導氣位置，當該推抵部542脫離該移動組43後，剩下的氣體會經由洩壓流道45而由該第三閥口333流出。Referring to Figures 7, 10, and 11, when the pedal 93 is stepped on to brake, the moving group 43 is located in the non-conducting position (see Fig. 4), as long as the air pressure of the pressure source 91 is driven through the normally open solenoid valve 94. After entering the fourth valve port 212, the air pressure pushes against the diaphragm 54 to move downward, so that the pushing portion 542 is pushed downward to move the moving group 43 to the air guiding position; when the pedal 93 When the brake is disengaged and the brake is disengaged, the air pressure of the fourth valve port 212 is released, and the diaphragm 54 is pushed back by the lower gas to return to the original position, and the movement group 43 is also subjected to the first The elastic force of the elastic member 44 moves upward to move the moving group 43 to the non-air guiding position. When the pushing portion 542 is separated from the moving group 43, the remaining gas passes through the pressure releasing passage 45. The third valve port 333 flows out.
參閱圖4、5、10，另外，當該踏板93受踩踏而進行煞車時，而該馬達部51故障而無法運作的情況下，且該止擋部613未抵於該擋塊241時，此時只要以該控制單元驅使該常閉電磁閥95導通而於該第五閥口211輸入氣流，並卸離該塞件25，氣流就會吹動該渦輪葉片53轉動，進而連動該蝸桿部52轉動，並連動該連動件61轉動使該止擋部613抵於該擋塊241，使該凸輪部612回到初始位置，此時就能透過該第四閥口212後而以氣壓推抵該膜片54，而使該膜片54做為備援使用。要說明的是，除了以氣流吹動該渦輪葉片53轉動的方式之外，也可以在卸離該塞件25後，以手工具（圖未示）穿入以撥動該渦輪葉片53，而達到相同的效果。Referring to FIGS. 4, 5, and 10, when the pedal 93 is stepped on to brake, and the motor portion 51 fails to operate, and the stop portion 613 does not abut the stopper 241, this When the control unit drives the normally closed solenoid valve 95 to conduct, and the air flow is input to the fifth valve port 211 and is disengaged from the plug member 25, the air flow blows the turbine blade 53 to rotate, thereby interlocking the worm portion 52. Rotating and interlocking the linking member 61 to rotate the stopping portion 613 against the stopper 241 to return the cam portion 612 to the initial position, and then the fourth valve port 212 can be transmitted through the fourth valve port 212 to push the air pressure The diaphragm 54 is used as a backup. It should be noted that, in addition to the manner in which the turbine blade 53 is rotated by the air flow, after the plug 25 is detached, a hand tool (not shown) is inserted to move the turbine blade 53. Achieve the same effect.
參閱圖7、10、11，本發明可用於控制車輛的前輪或後輪，取代原有的傳統快放閥或繼動閥。此外，在進一步的應用中，該氣壓煞車繼動閥也可以依需求運用在不同領域的該等制動室92（見圖10），所指的不同領域可以例如是不同種類的交通工具的煞車系統，當用在需要較快反應的部位時，可以透過該馬達部51進行驅動，而當用在不需快速反應的部位時，可以透過該膜片54來驅動。當以該馬達部51為主動源，並以該膜片54為備援時，本發明可運用於電控煞車系統（EBS），當以該膜片54為主動源，並以該馬達部51為備援時，本發明可運用於自動緊急煞車系統（AEB）。Referring to Figures 7, 10 and 11, the present invention can be used to control the front or rear wheels of a vehicle, replacing the conventional conventional quick release valve or relay valve. In addition, in further applications, the pneumatic brake relay valve can also be applied to the brake chambers 92 (see FIG. 10) in different fields according to requirements, and the different fields indicated may be, for example, brake systems of different types of vehicles. When used in a portion where a faster reaction is required, it can be driven through the motor portion 51, and when used in a portion where no rapid reaction is required, it can be driven through the diaphragm 54. When the motor portion 51 is used as an active source and the diaphragm 54 is used as a backup, the present invention can be applied to an electric brake system (EBS), and when the diaphragm 54 is used as an active source, the motor portion 51 is used. For redundancy, the present invention can be applied to an automatic emergency braking system (AEB).
值得一提的是，該氣壓煞車繼動閥除了是可以應用於車輛的煞車系統，也可以應用於具有彈簧的氣壓閥件的場合，而使氣壓閥件能夠達到自動化以及以氣壓及電力分別驅動氣壓閥件的效果。要說明的是，該馬達部51及該膜片54都可以作為主動源，也都可以作為備援使用。It is worth mentioning that the pneumatic brake relay valve can be applied to the brake system of the vehicle, and can also be applied to the pneumatic valve member with spring, so that the pneumatic valve member can be automated and driven by air pressure and electric power respectively. The effect of the pneumatic valve. It should be noted that both the motor portion 51 and the diaphragm 54 can be used as an active source, and can also be used as a backup.
綜上所述，藉由該馬達部51、該蝸桿部52、該連動件61、該從動件62、該壓板件42及該移動組43的設置，使該移動組43能夠直接被該馬達部51連動而於該導氣位置及該非導氣位置之間移動，可提升控制該作用空間34及該導氣空間35之間的通氣氣流大小的精確度、線性度及增快該氣壓煞車繼動閥的作動時間，因此能夠提高煞車線性度及精確度，以及快速反應作動，且該渦輪葉片53及該膜片54的設置，還能進一步於該馬達部51故障時能正常運作，故確實能達成本發明之目的。In summary, the movement group 43 can be directly used by the motor by the arrangement of the motor portion 51, the worm portion 52, the linkage member 61, the follower member 62, the pressure plate member 42, and the movement group 43. The portion 51 moves between the air guiding position and the non-air guiding position to improve the accuracy, linearity and increase of the airflow between the working space 34 and the air guiding space 35. The operating time of the movable valve can improve the linearity and accuracy of the brake, as well as the rapid reaction actuation, and the arrangement of the turbine blade 53 and the diaphragm 54 can further operate normally when the motor portion 51 fails, so The object of the invention can be achieved.
