u003cpu003e The engine must rely on external force to drive the crankshaft to rotate before it can enter the normal working state, and automobile engines are no exception. Normally, the whole process from the start of the crankshaft of the car engine to idle speed is called the engine start, which is usually realized by the ability of the car start battery. The circuit that completes this process is the start circuit. Modern cars all use electricity as the starting method, which is generally called the electric starter for short. The basic circuit composition of automobile starting The starting circuit of the automobile is composed of the starter as the core. When reading the starting circuit, it can be carried out around the starter. The components related to the starter are the battery, the total fuse, the ammeter, the starter, Start relay, ignition switch, etc. The basic circuit of car start is shown in the figure below. u003c/pu003eu003cpu003eu003c/pu003e Car start basic circuitu003cpu003eu003c/pu003eu003cpu003eThe graphic symbols and components of the starter are mostly installed on the seat hole at the front end of the flywheel housing of the car engine. In addition to a few models on the right side, most models are installed on the left side by using the flange hole of the starter rear cover. 1. Graphical symbols of the starter circuit The function of the starter is to start the car engine and then immediately stop working. The circuit symbol of the starter with electromagnetic switch is shown in the figure below. u003c/pu003eu003cpu003eu003c/pu003e Typical structure of automobile starter 2. The composition of the starter The starter is generally composed of a DC motor, a transmission mechanism and a control device. (1) DC motor The DC motor is a series-excited motor whose function is to generate a torque when the system is started. (2) Transmission mechanism The transmission mechanism of the starter was called meshing mechanism or meshing device. Its function is to enable the pinion to smoothly engage in the flywheel gear ring, and to disengage the flywheel gear ring smoothly after starting the engine. (3) Control device The function of the control device of the automobile starter is to control the on and off of the electric motor circuit, and at the same time manipulate the clutch and flywheel. u003c/pu003e
