1、 ABS introduction
1.1 what is ABS
ABS is the abbreviation of anti lock braking system, which is an electronic system to control and monitor the vehicle speed during braking. It works through the conventional braking system, and can improve the active safety of the vehicle. When ABS fails, the conventional brake system still works. ABS system mainly consists of ECU, ABS solenoid valve, wheel speed sensor and harness.
2.2 what are the advantages of ABS installation
In case of emergency braking, the maneuverability of vehicle direction is maintained; the braking distance is shortened and optimized. On the low adhesion road surface, the braking distance is shortened by more than 10%; on the normal road surface, the optimal utilization ratio of road adhesion coefficient - that is, the optimal braking distance is maintained. Reduced traffic accidents. Reduce the driver's mental burden. Reduced tire wear and maintenance costs.
2、 ABS solenoid valve
2.1 function of ABS solenoid valve
ABS solenoid valve is a main executive part of ABS system. It receives the electrical signal from ECU to charge, exhaust and maintain the pressure of brake chamber.
2.2 ABS solenoid valve of our company
Our company began to produce ABS solenoid valve in 2002, which is one of the earliest manufacturers in China. After more than 10 years of continuous improvement and improvement, the performance of the products has reached or even exceeded the performance of similar products abroad. Our company's ABS solenoid valve has been supporting for Guangzhou Kemei brake, Ruili group, Wan'an group, Haldex of Sweden, boreck of Jiaozuo and other companies, with an annual output of more than 500000.
增壓時，常閉閥及常開閥均不通電，氣源直接從 1 口進入閥體，推開增壓膜片，從2口進入制動氣室。
保壓時，常閉閥通電吸合，使氣源到達增壓膜片上腔，壓緊增壓膜片，同時另一路氣源從常開閥到達排氣膜片下腔，壓緊排氣膜片，達到保壓的目的。
減壓時，常閉閥通電吸合，使氣源到達增壓膜片上腔，壓緊增壓膜片，同時常開閥也通電吸合， 將排氣膜片下腔的氣通過 3 口排掉，這樣制動氣室的氣就能通過 2口推開排氣膜片，將制動室的氣從 3口排出。
車架上靠近制動室的位置，排氣口朝下。傾斜不超過30度，電磁閥到制動室的管子不超過 1.5m，管徑大于 9mm，1口接進氣，2口接制動室。
