How are car belt models divided, and how many belts are there in the car? What are the effects?

There are two types of automobile belts: A and B, A is narrow and B is wide. There are long and short, and the size is marked on the front of the outside of the belt in millimeters, and you can choose according to your own model.

Normal type: O, A, B, C, D, E, 3V, 5V, 8V;

Ordinary reinforced type: ax, bx, cx, dx, ex, 3vx, 5vx, 8vx;

Narrow V-band: SPZ, SPA, SPB, SPC;

Strong narrow V-band: XPA, XPB, XPC;

Each model of the V-belt specifies the cross-sectional size of the V-belt:

The cross-sectional dimensions of the A-type V-belt are: the top width is 13mm, the thickness is 8mm;

The cross-sectional dimensions of the B-shaped V-belt are: the top width is 17mm, and the thickness is;

The cross-sectional dimensions of the C-shaped triangle are: the top width is 22mm, and the thickness is;

The cross-sectional dimensions of the D-shaped V-belt are: the width of the top, the thickness is 19mm;

The cross-sectional size of the E-shaped V-belt is: the top width is 38mm, and the thickness is.

Corresponding size (width * height): o (10 * 6), a (.

It is usually three of a kind, and the functions are as follows:

1. Timing belt:

The function of the timing belt is to connect the upper and lower, and the upper connection is the timing wheel of the engine cylinder head, and the lower connection is the crankshaft timing wheel; The timing wheel is connected to the camshaft, which has a cam on it, and its contact point is a small rocker arm, which generates pressure through the power brought by the timing belt and plays the role of jacking.

2. Fan belt:

A belt driven by a crankshaft. Its main purpose is to drive the engine fan and water pump.

3. Generator belt:

The belt on the generator is driven by the engine through the belt pulley, some are driven by a belt, and some are generator belts with doors. The specific number of belts depends on the model, and the design manufacturer decides.

3 commonly used ones.

1. Timing belt:

Some cars do not, timing belt is an important part of the engine valve system, through the connection with the crankshaft and with a certain transmission ratio to ensure the accuracy of the intake and exhaust time.

2. Fan belt:

Driven by the crankshaft, the main purpose is to drive the engine fan and water pump.

3. Generator belt:

The belt on the generator is driven by the engine through the belt pulley, some are driven by a belt, and some have a special generator belt. The specific number of belts depends on the model, and the design manufacturer decides.

There are three types of belts commonly used in automobiles: fan belts, ribbed belts, and timing belts. Automotive belt installation position: In automotive applications, it is mainly installed in the crankshaft swing cam of automobile engine, water pump, generator, air conditioning compressor, power steering pump and other positions.

1. The fan belt is a belt driven by a crankshaft. Its main use is to drive engines, fans, and water pumps.

2. The ribbed belt, also known as the air conditioning belt, is used to drive generators, air conditioning compressors and power steering pumps. These belts are suspended from the crankshaft pulleys and are fastened by an air conditioning belt tensioner. When the belt is damaged, the power decreases and there is no power to steer; If you turn on the air conditioner, the air conditioner compressor does not start and cannot be cooled.

3. The timing belt is an important part of the engine valve system. Through the connection with the crankshaft and a certain transmission ratio, the accuracy of the intake and exhaust time is guaranteed.

The timing belt is used to start the piston stroke (up and down) and the valve opening and closing sequence (time) while the engine is running. With a timed connection, you should always run synchronously.

The engine drives various auxiliary equipment such as air conditioning compressors, power steering pumps, and alternators through belt drive. If the belt slips or breaks, the corresponding auxiliary mechanism will not work properly, which will affect the normal use of the car. Therefore, it is necessary to check the belt regularly.

There are more belts on the car, and the name is different. But basically there are two kinds, that is, air conditioning belts and fan belts.

The air conditioning belt is the one with air conditioning; The fan belt is to drive the fan, water pump, and generator, and because the fan rotates automatically on the trolley, it is not called a fan belt, but a generator belt.

Timing belt, the general gasoline car will use this kind of transmission. About 60,000 will have to be replaced.

Generators, water pumps, power steering pumps, air conditioning belts, etc., use one to three left and right corner belts. A good car may use a multi-slot, which lasts for a long time and is of good quality, but it is more expensive!

3 commonly used ones.

1. Timing belt Some cars don't have it.

2. The fan belt is driven by the crankshaft, and the main purpose is to drive the engine fan and water pump.

3. Generator belt The belt on the generator is driven by the engine through the belt pulley, some are driven by a belt, and some are driven by a special generator belt. The specific number of belts depends on the model, and the design manufacturer decides.

Engine beltsThe model number is a meaning indicating the specifications of the belt. The number of the belt model represents the size of the belt, and the belt model is printed on the front of the belt, generally speaking, the number in front of the belt is the section length, the middle refers to the model of the belt, and the number behind means the width.

The role of the timing belt

The timing belt is an important part of the engine valve system, the role of the timing belt is to play the role of connecting the upper and lower, the upper part of the dismantling and guessing Hu connection is the timing wheel of the cylinder head of the Zhaoxing engine, and the lower connection is the crankshaft.

Timing wheel. The timing wheel is connected to the camshaft.

This cam travel shaft has a cam, and its contact point is a small rocker arm, which generates pressure through the power brought by the timing belt and plays the role of jacking.

The function of jacking up the intake valve is to let the atomized gasoline enter the cylinder block, and when the exhaust valve is jacked up, the exhaust gas is discharged out of the cylinder block, when the camshaft is concave (note: not a raised place) at the same time when it touches the small rocker arm, then the intake valve and exhaust valve are closed, and the compression ratio.

Generation, distributor ignition, internal combustion starts and generates power.

Nowadays, there are two kinds of belts in cars

One is the generator belt and the other is the timing belt.

The generator belt is the most important belt on the car, connecting the generator, air conditioning compressor, booster pump, lazy rock Karen pulen, tensioner pulley and crankshaft pulley, etc., its power source is the crankshaft pulley, the power is provided by the rotation of the crankshaft, and then the rough tremor calls the belt hole stool to move other parts to run together.

The timing belt is connected to the camshaft and camshaft. The crankshaft is connected to the piston, and when the crankshaft rotates, the piston moves up and down, and the cam is connected to the throttle to control the opening and closing of the throttle.

There are five belts in the car, namely: engine timing belt, engine balance shaft belt, generator, water pump belt, air conditioning belt, and power pump belt.

The role of the five belts:

1. The function of the engine compartment belt is that when the engine is running, the crankshaft pulley drives the generator pulley to run to generate electricity to the generator.

2. The function of the balance shaft belt is to drive the balance shaft, which helps to balance the stable work of the Huai San shaft.

3. The function of the automobile water pump belt is to drive the water pump to run. Once the power pump belt is broken, it will have an impact on driving, the steering wheel will rotate very heavily, and there are potential safety hazards during driving, so it needs to be replaced with a new one in time.

4. The function of the air-conditioning belt is to drive the generator, air-conditioning compressor, and steering power pump, which are hung on the crankshaft belt pulley, and the air-conditioning belt tensioner is tightened.

5. The function of the booster pump belt is to drive the operation of the water pump. <>
