Automotive
In recent years, with the development of hydraulic technology and its application in automobiles, the various performances of automobiles have been greatly improved, especially in modern automobiles, the high-tech of computer, electromechanical and hydraulic integration has been used, which has made the development of automobile industry reach a new level. Hydraulic technology has been widely used in today's technologically advanced automobiles, and even the fuel supply and mechanical lubrication systems of automobiles have also borrowed these technologies.
Application of Hydraulic Technology in Automobiles
1. Automatic transmission hydraulic control system
The hydraulic oil output by the oil pump is distributed to each component to control the engagement and separation of each clutch and brake, so as to achieve the purpose of automatic gear shifting.
2. Automotive Hydraulic Suspension System
The electronically controlled hydraulic suspension of automobiles can make drivers and passengers feel comfortable on soft springs, and can also ensure the flexibility and stability of the automobile. It also has the function of adjusting the damping force to improve the stability of the vehicle. Changes in vehicle attitude can also be suppressed during sharp turns, rapid acceleration and emergency braking.
3. Automotive hydraulic brake system
Due to frequent or long-term use of the brakes, the phenomenon of overheating and recession of the friction plates will occur, and in severe cases, the brakes will fail, threatening driving safety. In order to solve this problem, the braking systems of various vehicles have developed rapidly, and the hydraulic retarder is one of them. Today's hydraulic retarders are mainly used in heavy-duty trucks and large and medium-sized passenger cars.
4. Electro-hydraulic braking system
The EHB replaces the pressure regulator and ABS module in conventional brakes with an integrated brake module. This integrated braking module is composed of electric motor, pump, battery and other components. It can generate and store braking pressure, and can individually adjust the braking torque of the four wheels. At the same time, corresponding programs are designed in the electronic control system of EHB, and functions such as ABS and ASR can be fully realized by manipulating the electronic control components to control the magnitude of the braking force and the distribution of the braking force of each axis.
