No longer silly and indistinct, what's the difference between these auto parts do you know?

Some parts of the car, the name is very similar, for some car white, always silly and indistinct. Today, Lao Hou has sorted out the names of parts that are confusing on the car. Let's take a look at the difference between them.

Chassis and body outsole

This is a concept that many people will mistake. Everyone often talks about driving the chassis and doing it.

Chassis armor

The chassis rusted, and so on. In fact, what they say is not the chassis of the car, but the outsole of the car body. It is a whole piece of structure assembled from the front floor assembly and the rear floor assembly, and it is complete with the above ABC column and side walls. The body is part of the body structure.

The chassis of an automobile refers to the general term of the clutches, transmissions, drive trains, suspensions, steering systems, and brake systems. It is a functional part of the car.

Wheel rims and wheels

Wheels and wheels are two different things. Many articles confuse them, but in fact they are two very different parts. As shown below.

The hub is mounted on the shaft tube or knuckle (the brake disc is mounted on the hub) by means of a conical ball bearing. The rim is used to mount the tire and it is connected to the hub by a tire screw.

Generator belt and timing belt

Many vehicles use timing belts, but many people do not know which one is the timing belt. The belt that is exposed on the front of the engine and wound around the generator is a timing belt. It is actually a generator belt that is used to drive the generator. Air conditioning compressors, steering pumps, etc. The real timing belt is invisible and is blocked by a cover.

Valves and Throttle

The valve is the valve that the outside air enters into the engine and the exhaust gas of the engine is exhausted. It is responsible for inputting air into the engine and discharging the exhaust gas. It is installed in the cylinder head of the engine. The throttle is a valve that controls the air to enter the engine and is installed in the air filter. Between the device and the intake manifold, controlled by the accelerator pedal, there are pull-wire type and electronic control type. Actually, fuel injection and oil reduction is to change the size of the throttle opening to control the size of the intake air, and the fuel system will then eject the corresponding The fuel is mixed with it to form combustible mixtures of different concentrations and amounts into the combustion chamber.

Differentials and differential locks

In the straight running process of the car, the rotation speeds of the two driving wheels are the same, but in the cornering, because the wheel travel distance is not equal, the rotation speed is certainly not the same. The function of the differential is to allow the driving wheels on the left and right sides to be different. The speed of operation. The differential lock is an accessory on the differential, but the effect is just the opposite of the differential. The purpose is not to allow the differential to work. It is not allowed to have the same speed on both sides of the drive wheel.

Axle and transmission shaft

Axle shafts are solid shafts that transmit the torque of the transaxle to the drive wheels, while the drive shafts transmit the torque of the transmission to the drive axle. There is no drive shaft on the front-wheel drive car, and both the drive shaft and the half-axis on the rear-wheel drive car.

Bumper and crash beam

Many people confuse the bumper with the anti-collision steel beam. In fact, they are two completely different components. The anti-collision steel beam is part of the body frame structure, especially the front anti-collision steel beam, which plays a crucial role in the body structure. However, the bumper is just a body exterior cover that does not have any effect on the safety of the vehicle body structure. At best, it can be buffered in a very slight collision.

Valve cover and cylinder head

Some vehicles have been used for a long time and the valve cover will leak. This is a small thing. However, some owners have no idea where they are. Everyone says that their own cylinder heads have leaked, and they startle some people who understand the car and think that the engine of this car is out of order. In fact, the valve cover and the cylinder head are two distinct components. The valve cover is attached to the cylinder head. The removal of the valve chamber cover is a very simple operation, and the disassembly and assembly of the cylinder head is very complicated, has a certain technical difficulty, requires the attachment and detachment of many attachments, and also takes a long time, and also has some damage to the engine.

Air filter and air filter

Air filter cartridges and air-conditioning filter cartridges are indistinguishable from their names. In fact, as long as you remember this point: air filter is to supply air to the engine, air filter is to supply gas to the people in the car. The air filter is generally installed in the engine compartment, and the air filter is generally installed in the co-driver's glove box.

Glass water, antifreeze

Glass water, as its name implies, is used to clean the front windshield; antifreeze is

Engine cooling system

The working medium has the effect of cooling the engine, preventing the cooling system from freezing and scaling.

It should be noted that these two liquids have different locations, so don't add them wrong. The wrong result is very serious.

Reviews

Some parts of the car, either with similar names or similar functions, are always confusing. Just like Fan Bingbing and Li Bingbing in the entertainment scene, for people like me who are blind, they have almost no difference. However, it does not matter if they do not recognize them. They do not know the parts on the car. The consequences can be serious. In the event that glass water is added to the engine one day, or the generator belt is replaced with a timing belt, you can wait for the output of Mao Yeye.
