阻尼可控式半主动悬架系统技术解析damping controllable semi active suspension system Semi active suspension can be regarded as the variable characteristics of the spring and (or) suspension shock absorber composition, although it can not be withInput outside of optimal control and regulation, but it according to various conditions of storage in the computer next spring and shock absorberParameter optimization of instructions to adjust the stiffness of the spring and shock absorber damping state. Changing the spring stiffness in the semi active suspension systemThan a change of damping is difficult, so in the semi-active suspension system with variable damping suspension system is the most common. Semi active suspension structureSimple, the price is relatively cheap, so people pay more and more attention.Semi active suspension system control functions are as follows: 1. The anti car tail squat control; prevent shifting impact control;To prevent the head sinking control; the anti roll control; the car at high speed body down control.(1) Delphi two gear automatic real-time damping adjustment system (BBR\PD). Delphi (Delphi) the companys two gearReal time automatic damping adjustment system (Bi *late Real a [lime Damping, BSRTD) is a kind of semi - active, since the two gearThe damping adjustment system, human information transmission body and wheel movement, speed, angle, brake and other multiple sensor based, canTo make real-time response of pavement condition and driving condition, both factory ride comfort and handling performance.The system consists of 4 with piston valve two gear controllable damping shock absorber, 4 motion sensors and 1 controller, electric controlUnit constitute, and optional 1 steering angle sensor and the mode selection switch. System structure as shown in fig..Delphi two gear automatic real-time damping adjustment system of BSRTD (see PPT)(2) Tenneco continuous electronic control suspension system (CES}.
