Vehicle Starter Common Faults and Maintenance Suggestions
As we all know, the start of the engine requires the support of external forces, and the car starter is playing this role. The starter can convert the battery's electrical energy into mechanical energy and drive the engine's flywheel to rotate to start the engine. In general, the starter uses three components to achieve the entire starting process. The DC motor introduces the current from the battery and causes the starter drive gear to produce mechanical motion; the drive mechanism meshes the drive gear into the flywheel ring gear and can be automatically disengaged after the engine starts; the starter circuit is turned on and off by a solenoid switch. To control. Among them, the motor is the main component inside the starter, and its working principle is the energy conversion process based on the Ampere's law that we come into contact with in the junior middle school physics, that is, the energized conductor is subjected to the force in the magnetic field. The motor includes necessary components such as armature, commutator, magnetic pole, brush, bearing and housing.
a:
1. After the start switch is turned on, the starter rotates at high speed and the engine crankshaft does not respond. This phenomenon indicates that the fault occurred on the starter's transmission mechanism, which may be caused by wear of the transmission gear or the one-way clutch.
2. The starter does not work properly and the drive gear does not turn. There are many causes for this phenomenon, such as problems with the power cord, contact switch ablation of the starter switch, and excessive engine resistance.
3. The starter power output is insufficient to drive the crankshaft. Short circuit of the excitation coil and loss of battery power may cause the starter to have insufficient power.
4. The starter operation sounds harsh. This may be caused by the jamming of the one-way clutch or improper installation of the starter.
5. There is a "click" sound when the starter switch is turned on, but it does not work. Keeping the coil disconnected or a serious battery loss can cause this phenomenon.
Maintenance advice:
The starter is a valuable part of the car and will not be easily damaged. However, in order to extend the service life of the starter, appropriate methods of use are also required. In the process of starting the engine, the starter must introduce 300 to 400 Ah of electricity from the battery. Therefore, in order to prevent the battery from over-current or damage, the start-up time should not exceed 5 s. In winter, it is easy to start difficult. The start time should not be too long for each start, and appropriate intervals should be left for each start.
