在汽车电气控制系统中,继电器的作用至关重要,通过控制一路线路的通断来控制另外一路的通断,从而实现了电路的实时控制,它的应用非常广泛,主要包括汽车总电源、起动、预热、空调、灯光、喇叭、电动门窗、防抱死制动等控制电路中。本文阐述了继电器在汽车起重机底盘电气系统中的应用,包括器件选型、典型电路设计和电路设计技巧等。
In the automotive electrical control system, the role of the relay is crucial. By controlling the continuity of one line to control the continuity of the other, the real-time control of the circuit is realized. Its application is very broad, including the main power supply of the vehicle, starting , Preheating, air conditioning, lighting, speakers, electric windows and doors, anti-lock brake control circuit. This article describes the relay in the automotive crane chassis electrical system applications, including device selection, the typical circuit design and circuit design skills.
