What is the classification of car starter starters?

Usually called the starter, the starting of the engine needs the support of external force, and the car starter is playing this role.

Among the three components of the starter, there is generally no essential difference in the motor part, and it can be divided into ordinary starter and permanent magnet starter according to the form of the DC motor used; The control device and the transmission mechanism are very different, so they are generally classified according to the difference of the control device and the transmission mechanism.

1) Classified by control device.

Directly operated starter: It is the main circuit switch of the starter directly controlled by the foot pedal or hand-pulled lever linkage mechanism to turn on or off the main circuit, also known as mechanical starter. Although this mode is simple in structure and reliable in operation, it is rarely adopted because the starter and the battery are required to be close to the cab, and are limited by the installation layout, and the operation is inconvenient;

Electromagnetic control starter: It is controlled by a button or ignition switch, and then the main switch of the starter is controlled by the relay to turn on or off the main circuit, also known as an electromagnetic control starter. This method can realize long-distance control, easy to work, and is widely used in modern cars.

2) Classification according to the meshing mode of the transmission mechanism:

Inertial meshing: obsolete;

Forced meshing type: reliable work, convenient operation, wide application;

Armature mobile type: complex structure, high-power diesel vehicle;

Gear moving: the electromagnetic switch pushes the meshing rod;

Deceleration: small mass and complex structure and process.

1. According to the type of power, automobile engines can be divided into diesel engines, gasoline engines, electric vehicle motors and hybrid vehicles.

2. According to the classification of the air intake system, it can be divided into four types: naturally aspirated, turbocharged, mechanically supercharged and double-pressed.

3. According to the piston movement mode, it can be divided into two types: reciprocating piston internal combustion engine and rotary piston engine.

Fourth, according to the cylinder arrangement type, it is divided into in-line engine, V-type engine, W-type engine and horizontally opposed engine.

5. According to the number of cylinders, it can be divided into single-cylinder engine and multi-cylinder engine. Modern cars mostly use three-cylinder, four-cylinder, six-cylinder, and eight-cylinder engines.

6. According to different cooling methods, it can be divided into water-cooled engine and air-cooled engine.

7. According to the number of strokes, it can be divided into four-stroke internal combustion engine and two-stroke internal combustion engine.

8. According to the classification of fuel **, carburetor engine, EFI engine and in-cylinder direct injection engine. Hope the above is helpful to you, thanks.

The types of starters are: 1) Conventional starters: the drive gear rotates at the same speed as the armature, and there is no deceleration mechanism.

2) External meshing reduction type starter: reduce the armature speed and increase the torque through the reduction gear. 3) Planetary gear type starter:

The planetary gear transmission mechanism reduces the armature speed and increases the driving torque.

4) Planetary deceleration-rectifier conductor (PS) type starter: This type of starter uses a permanent magnet to generate a magnetic field, and the drive gear is meshed or disengaged from the flywheel ring gear through the transmission rod. Car engines.

The whole mainly has a crank connecting rod mechanism, a valve mechanism, a fuel sail system, a cooling system, a lubrication system, an ignition system and a starting system.

The starting system is to make the crankshaft.

Rotation completes the engine starting process. The starter is the core component of the starting system. The starter is composed of three parts: DC series motor, transmission mechanism and control device.

The starters used on different types of cars are DC motors despite their different forms.

Some of them are basically similar, but the main difference is that the transmission mechanism and control device are different.

1) The function of the DC series motor is to convert the electrical energy input from the battery into mechanical energy.

Electromagnetic torque is generated.

2) The transmission mechanism is also known as the starter clutch and mesh. The function of the transmission mechanism is to make the pinion on the starter shaft mesh into the flywheel tooth ring when the engine starts, and transmit the torque of the starter to the engine crankshaft; After the engine starts, the starter pinion and the flywheel tooth ring can be automatically disengaged.

3) The control device is also known as the starter switch. The function of the control unit is to turn on and off the circuit between the motor and the battery, and at the same time to connect and disconnect the additional resistors of the ignition coil.

From the point of view of the components of the starter, there is generally no essential difference in the motor part, and it can be divided into ordinary starter and permanent magnet starter according to the form of the DC motor used; The control device and the transmission mechanism are very different, so they are generally classified according to the difference between the control device and the starter mechanism of the transmission car.

1. Classification according to control devices;

1) The direct operated starter is the main circuit switch of the starter directly controlled by the foot pedal or hand-pulled lever linkage mechanism to turn on or off the main circuit, also known as the mechanical starter. Although this mode is simple in structure and reliable in operation, it is rarely adopted because the starter and the battery are required to be close to the cab, and are limited by the installation layout, and the operation is inconvenient;

2) The electromagnetic control starter is controlled by a button or ignition switch, and then the main switch of the starter is controlled by the relay to turn on or cut off the main circuit, also known as the electromagnetic control starter. This way can realize long-distance control, easy to work, in the modern state of the collapse of the car.

widely adopted.

2. Classification according to the meshing mode of the transmission mechanism Inertial meshing starter When the starter rotates, its meshing pinion depends on the inertial force.

Automatic engagement of the flywheel tooth ring. After starting, the pinion automatically detaches from the flywheel ring by inertial force. This kind of meshing mechanism has a simple structure, but can not transmit a large torque, and the reliability is poor, and it has been rarely used.

There are three types of starters: deceleration starters, permanent magnet starters, and permanent magnet deceleration starters.

Deceleration starter: The gear reducer of the starter has three different forms: external meshing, internal meshing and planetary gear. An external gear reducer starter, the reducer mechanism is driven in the middle between the armature shaft and the starter drive gear, and the electromagnetic switch core is coaxial with the drive gear, and the drive gear is directly driven to mesh, without the need for a fork.

The internal deceleration starter is suitable for high-power starters due to the small transmission center distance and large reduction ratio of the deceleration mechanism. The reducer mechanism of the planetary gear reduction starter is compact. The transmission ratio is large and the efficiency is high.

Permanent magnet starter: The starter with a permanent magnet as the magnetic pole is called a permanent magnet starter. The excitation winding and pole core in the traditional starter are eliminated, the structure of the starter is simplified, the volume and mass are greatly reduced, the reliability is improved, and the metal material is saved.

Permanent magnet deceleration starter: The starter with a high-speed and low-torque permanent magnet motor and gear reducer between the drive gear and the armature shaft is called the permanent trapped Ling magnetic deceleration starter. The volume and mass of permanent magnet deceleration starters can be further reduced, and they have been widely used.

According to the excitation method, it is classified as follows:

1) Excitation starter. The excitation starter is a series DC motor, which relies on the excitation winding.

The magnetic core establishes a magnetic field, and the structure is slightly complex, but the output torque and power are very large, so the application is extreme.

Extensive. 2) Permanent magnet starter. The permanent magnet starter uses a permanent magnet material as the magnetic pole and cancels the excitation type.

The excitation winding and pole core in the starter are simplified in structure, small in size, light in weight, and economical

metal materials. However, the power of the permanent magnet starter is generally small, and the range of use is affected to a certain extent.

to the limit. Lu Yu (2) according to the transmission mechanism classification is as follows;

1) Ordinary accompaniment rock starter. The starting torque generated by the armature of the motor is directly passed through the clutch and drive.

The starter in which the moving gear is transmitted to the flywheel ring gear is called an ordinary starter.

2) Deceleration starter. The basic structure of the deceleration starter is the same as that of the ordinary starter, except in.

Between the armature and the driving gear, a reduction gear (generally the reduction ratio is 3 4) is installed, and the torque is increased by deceleration.

After that, the number of mountains drives the drive gear. Deceleration starter is the development direction of automotive starter in the future.

Hello, the classification of starters are: 1. Traditional shed sliding type starter: the drive gear and armature rotate at the same speed, without a deceleration mechanism.

2. Meshing reduction type starter: reduce the armature speed and increase the torque through the reduction gear. 3) Planetary gear type starter:

The planetary gear transmission mechanism reduces the speed of the car armature and increases the carrying torque of the drive chain.

Starter is divided into ordinary starter (QD), deceleration starter (QDJ), and permanent magnet starter (QDY).

There are four main types of starters: reduction type, traditional type, planetary type, and planetary reduction-rectifier conductor electric type.

1) The deceleration type starter with a gear reducer between the armature shaft and the drive gear is called a deceleration starter. The gearing starter uses a compact, high-speed electric motor that reduces the rotational speed of the armature by reducing the speed of the reduction gear to increase the rotational torque. The moving core of the solenoid switch directly pushes the pinion on the same shaft as it and engages it with the ring gear.

2) The pinion of the conventional type starter is on the same shaft as the armature and rotates at the same speed. The dissipating lever attached to the magnetic switch pushes the pinion and engages it with the ring gear.

3) Planetary Starter has a planetary gear that is used to reduce the rotational speed of the armature. The digging pinion is meshed with the ring gear by means of a drive rod, just like the conventional type.

4) Planetary Deceleration-Rectifier Conductor Electric Type Planetary Reducer-Rectifier Conductor Motor Model The starter uses a permanent magnet in the magnetic field coil, and the operation of meshing and disengaging gears is the same as that of the planetary starter.

The types of starters are as follows:

1. According to the excitation mode of the starter:

1) Permanent magnet starter;

2) Exciter starter;

2. According to the structure of the starter:

1) Slow down and start to quietly regret the motive;

2) Ordinary quiet noise slag starter;

3. According to the meshing mode of the starter:

1) Mechanically forced engagement starter;

2) Electromagnetic meshing starter.

According to the overall structure of the starter, it can be divided into electromagnetic type, permanent magnet type and deceleration type starter. According to the different meshing methods of the conveyor, it can be divided into forced meshing type and armature moving type.

According to the different classifications of transmission and excitation methods, transmission is divided into ordinary and deceleration, and excitation is divided into, electromagnetic and permanent magnet.

The starter you said is probably for the vehicle, their structure is actually a DC motor, the working principle is to add direct current to the stator coil, connect in series to the commutator and commutator, and convert the electrical energy into magnetic energy to make the starter run. Classification: I have seen two types of 12V and 24V according to voltage, and two types of local speed and deceleration start according to mechanical.

It is divided into high-speed and low-speed. The gear at high speed is small and the sound is small.

The starting motor works the same way.
