Description

介入式流體煞車系統Intervention fluid brake system

本創作相關於一種流體煞車系統，特別是相關於一種介入式流體煞車系統。The present invention relates to a fluid brake system, in particular to an interventional fluid brake system.

隨著經濟發展迅速，運輸作業的需求量大幅增加，貨車等大型運輸車輛因運輸機動性佳、維護成本低，故被廣泛使用於各種運輸作業。這類大型運輸車輛對於駕駛人員的依賴非常高，但由於現階段專業駕駛人員需求量大，加上人力短缺，對於駕駛人員的要求僅需合格駕照即可，導致每位駕駛的安全駕駛知識都不相同，常常有煞車距離不足、車速過快，造成交通事故頻傳。With the rapid economic development, the demand for transportation operations has increased significantly. Large transportation vehicles such as trucks are widely used in various transportation operations due to their good transportation mobility and low maintenance costs. Such large-scale transport vehicles are very dependent on drivers. However, due to the high demand for professional drivers at this stage and the shortage of manpower, the requirements for drivers are only a qualified driver's license, resulting in every driver's safe driving knowledge. Not the same, there are often insufficient braking distance and excessive speed, resulting in frequent traffic accidents.

為了提升安全性，有些車輛會安裝有自動煞車系統來進行輔助駕駛人員進行緊急煞車。然而，對於原先沒有安裝這類自動煞車系統的車輛而言，要加裝自動煞車系統往往必須要將原車輛的煞車系統全部更換，工程浩大且所費不貲。另一方面，習知的自動煞車系統中，流體煞車依靠的是電磁閥的開閉來進行自動煞車與人工煞車的流路切換，致使其緊急狀況反應時間受到電磁閥的運作速度的限制。In order to improve safety, some vehicles will be equipped with automatic braking systems to assist drivers in emergency braking. However, for a vehicle without such an automatic braking system originally installed, it is often necessary to replace all the braking systems of the original vehicle to install an automatic braking system, which is a huge and expensive process. On the other hand, in the conventional automatic braking system, the fluid braking relies on the opening and closing of the solenoid valve to switch the flow path between the automatic braking and the manual braking, so that the emergency response time is limited by the operating speed of the solenoid valve.

因此，本創作的目的即在提供一種介入式流體煞車系統，可簡單且低成本地設置於車輛，且緊急狀況反應時間更快，以提升行車安全。Therefore, the purpose of the present invention is to provide an interventional fluid braking system, which can be installed in a vehicle simply and at low cost, and has a faster emergency response time, so as to improve driving safety.

如第1圖所示，依據本創作的一實施例的一介入式流體煞車系統100係附加設置於一車輛V，該車輛具有相互流體連接的一煞車控制器V1、一煞車流體源V2、及一煞車分泵V3，該車輛V藉由該煞車控制器V1控制該煞車分泵V3而進行一人工煞車及／或一主動煞車，該介入式流體煞車系統100包含：一主動切換三通閥1、一電控壓力控制器2及一介入煞車控制裝置3。As shown in FIG. 1, an interventional fluid braking system 100 according to an embodiment of the present invention is additionally disposed on a vehicle V, and the vehicle has a brake controller V1, a brake fluid source V2, and a fluid connection with each other.

此外，為了更好理解本創作的技術，以下配合第3圖至第6圖，對本創作的介入式流體煞車系統100附加設置於習知車輛V的情況進行說明。In addition, in order to better understand the technology of the present invention, a case where the interventional fluid brake system 100 of the present invention is additionally installed on a conventional vehicle V will be described below with reference to FIGS. 3 to 6 .

第3圖為顯示習知車輛V的流體煞車系統，其中該煞車控制器V1為一煞車踏板，位於圖中上側的煞車流體源V2（例，前煞車儲氣筒）經由該煞車踏板而流體連接於位於圖中左側的二個煞車分泵V3（即，左前輪煞車分泵、右前輪煞車分泵）。另一方面，該煞車踏板流體連接於位於圖中下側的煞車流體源V2（例，後煞車儲氣筒），並且經由一中繼閥V4而流體連接於位於圖中右側的二個煞車分泵V3（例，左後輪煞車分泵、右後輪煞車分泵），該中繼閥V4亦與該後煞車儲氣筒流體連接。FIG. 3 shows a fluid brake system of a conventional vehicle V, wherein the brake controller V1 is a brake pedal, and a brake fluid source V2 (eg, a front brake air reservoir) located on the upper side of the figure is fluidly connected to the brake pedal via the brake pedal.

第4圖為顯示本創作的實施例的介入式流體煞車系統100附加設置於習知車輛V時的情況。第3圖和第4圖的煞車系統之間的主要差異在於：該煞車踏板與該左前輪煞車分泵及該右前輪煞車分泵之間的直接流體連接改變成為經由根據本創作的實施例的該介入式流體煞車系統100的該主動切換三通閥1及該電控壓力控制器2等構件所構成的一煞車控制閥件組10而流體連接，且前煞車儲氣筒進一步流體連接於該煞車控制閥件組10。另一方面，該煞車踏板與該中繼閥V4之間的直接流體連接改變成為經由另一煞車控制閥件組10而流體連接，且後煞車儲氣筒進一步流體連接於該煞車控制閥件組10。從圖中可看出，習知車輛V的原有的流體煞車系統的該煞車控制器V1、該煞車流體源V2、該煞車分泵V3、該中繼閥V4皆仍然存在，且彼等之間的連接關係幾乎不變。也就是說，本創作的該介入式流體煞車系統100能夠在無須大幅更換原車輛V的煞車系統的情況下簡單且低成本地設置。FIG. 4 shows a situation when the interventional fluid brake system 100 according to the embodiment of the present invention is additionally installed on a conventional vehicle V.

On the other hand, the direct fluid connection between the brake pedal and the relay valve V4 is changed to be fluidly connected via another brake control valve assembly 10 , and the rear brake air reservoir is further fluidly connected to the brake control valve assembly 10 . . As can be seen from the figure, the brake controller V1, the brake fluid source V2, the brake sub-pump V3, and the relay valve V4 of the original fluid brake system of the conventional vehicle V still exist, and they all still exist. The connection relationship between them is almost unchanged. That is to say, the interventional fluid braking system 100 of the present invention can be installed simply and at low cost without greatly replacing the braking system of the original vehicle V.

第5圖為顯示根據本創作的實施例的介入式流體煞車系統100附加設置於習知車輛V而進行一人工煞車時的示意圖。從圖中可以看出，在附加設置有本創作的該介入式流體煞車系統100的情況下，習知車輛V進行人工煞車時，藉由該煞車控制器V1的操作，煞車流體進入該煞車控制閥件組10，經由該主動切換三通閥1而能夠直接到達該左前輪煞車分泵及該右前輪煞車分泵，或是進一步經由該中繼閥V4而能夠到達該左後輪煞車分泵及該右後輪煞車分泵。此情況和該車輛V原有的流體煞車系統進行人工煞車的情況幾乎無異。也就是說，本創作的該介入式流體煞車系統100並不影響該車輛V原有煞車之性能，且原有煞車之操作方式亦無改變。FIG. 5 is a schematic diagram showing when the interventional fluid braking system 100 according to an embodiment of the present invention is additionally installed on a conventional vehicle V to perform a manual braking. As can be seen from the figure, in the case where the interventional fluid braking system 100 of the present invention is additionally provided, when the conventional vehicle V performs manual braking, the braking fluid enters the braking control by the operation of the braking controller V1 The valve assembly 10 can directly reach the left front wheel brake cylinder and the right front wheel brake cylinder through the active switching three-way valve 1, or further through the relay valve V4 and can reach the left rear brake cylinder and the right rear wheel brake cylinder. This situation is almost the same as the situation in which the original fluid brake system of the vehicle V performs manual braking.

During the intervention braking, the electronically controlled pressure controller 2, under the control of the intervention braking control device 3, inputs the braking fluid from the braking fluid source V2 into the braking control valve assembly 10, and through the active switching three Through valve 1, it can also directly reach the left front wheel brake cylinder and the right front brake cylinder, or further through the relay valve V4 and can also reach the left rear brake cylinder and the right rear brake cylinder. , so as to perform the intervention braking with the same performance as the manual braking.

藉由上述結構，本創作的該介入式流體煞車系統100藉由該主動切換三通閥1並聯於原車輛V的煞車系統，故無須大幅更換原車輛V的煞車系統，而可簡單且低成本地設置，並且亦不影響原有煞車之性能，使駕駛人員無須重新學習煞車系統之操作方式。再者，本創作的該介入式流體煞車系統100藉由主動切換三通閥1而直接以煞車的流體壓力來進行流路切換，比起習知技術的電磁閥切換，緊急狀況反應時間能夠有效提高，進一步提升行車安全。With the above structure, the interventional fluid braking system 100 of the present invention is connected in parallel with the braking system of the original vehicle V through the active switching three-way valve 1, so it is not necessary to substantially replace the braking system of the original vehicle V, and it is simple and low-cost. It can be set in place without affecting the performance of the original brake, so that the driver does not need to re-learn the operation mode of the brake system. Furthermore, the interventional fluid brake system 100 of the present invention directly switches the flow path by the fluid pressure of the brake by actively switching the three-way valve 1 . Compared with the solenoid valve switching of the prior art, the emergency response time can be effectively improved. Improve and further improve driving safety.
