What are the parts of a car? What are the components of a car?

1 Engine The engine is the power unit of a car. Its role is to generate power from the combustion of fuel, and then drive the wheels through the transmission train of the chassis to drive the car. There are two main types of engines: gasoline engine and diesel engine.

The gasoline engine consists of a crank connecting rod mechanism, a valve mechanism and a fuel supply system, a cooling system, a lubrication system, an ignition system, and a starting system. The ignition method of diesel engine is compression-ignition, so there is no ignition system.

2 chassis The role of the chassis is to support and install the automobile engine and its various components and assemblies, form the overall shape of the car, and accept the power of the engine, so that the car can move and ensure normal driving. The chassis is composed of four parts: the drive train, the driving system, the steering system and the brake system.

3 Body The body is mounted on the frame of the chassis and is used for the driver, passengers to ride or load cargo. The body of cars and buses is generally an integral structure, and the body of trucks is generally composed of two parts: the cab and the cargo box.

4 Electrical equipment Electrical equipment consists of two parts: power supply and electrical equipment. Power sources include batteries and generators. Electrical equipment includes the starting system of the engine, the ignition system of the gasoline engine and other electrical devices.

The automobile chassis is composed of four parts: the transmission system, the driving system, the steering system and the brake system. The role of the chassis is to support and install the automobile engine and its various components and assemblies, form the overall shape of the car, and accept the power of the engine, so that the car can move and ensure normal driving. Auto chassis parts are divided into:

1. Transmission system: clutch, transmission, final reducer, half shaft, universal joint, transmission shaft.

<> "What are the parts of the car?

There are thousands of parts on a car, but when someone asks "what is a car made of", many people don't know where to start. Generally speaking, people divide the car into four main parts.

1.Bodywork. Let's start with the bodywork.

The body is the part of the vehicle that is used to carry people or goods. Including the body body (frame), body exterior parts, body interior parts, and wide body electrical accessories. The body of cars and buses is generally an integral structure.

The body of the truck is generally composed of two parts: the cab and the cargo box. The body is divided into "load-bearing body", "semi-load-bearing body" and "non-load-bearing body" according to other load-bearing chassis structures. For example:

The engine, gearbox and other chassis parts of the car are directly connected to the body body, and the body needs to carry their weight, so it is a load-bearing body; (Do you know what the "one box", "two hatchbacks, and three cars" of the load-bearing body mean?) ）

The truck chassis has a separate girder to carry the chassis assembly, and the body is only responsible for bearing the load of personnel and goods, so it is a non-load-bearing body.

It can be seen that the load-bearing capacity of the load-bearing body is relatively inferior to that of the non-load-bearing body due to the load of the chassis. However, due to the compact structure and the more integral vehicle, it has low noise and low weight, and is generally used in cars and other models. Due to the more powerful load-bearing performance of the non-load-bearing body, in addition to trucks, there are many hard-core off-road vehicles that will adopt a non-pure wild load-bearing body structure.

2.Motor.

After removing the body, we can find a clever way to call the heart of the car - the engine at a glance. Although the evaluation content of the first teachers classifies the engine into the chassis part of the explanation, due to the complex structure and principle of the engine, it is often listed as a separate part. In addition, the engine mentioned here actually includes all its accessories, such as fuel tank, exhaust after-treatment system, etc., they can correspond to the "five major mechanisms" and "two major systems" of the engine.

3.Chassis. In addition to the body and engine, the rest of the frame (as mentioned earlier, there is no separate frame for the load-bearing body), gearbox, rear axle, wheels, etc., all belong to the chassis part.

According to different functions, the chassis can be divided into four major systems: driving system, steering system, transmission system and brake system. We'll go into this part separately later.

4.Electrical equipment.

Electrical equipment is mainly composed of power supply system, electrical equipment and power distribution device. It can be seen that in fact, the electrical equipment is embedded in the other three parts, but it is like a dense net, connecting the various mechanisms of the car together, and at the same time, like a commander, coordinating the work of each part. Therefore, it is very important to list this part separately for the overall design of the vehicle.

It consists of four parts: engine, chassis, body, and electrical equipment.

The main role of the various parts of the car is:

1) Engine: The power device of the car, its function is that the fuel is burned in the cylinder, generating a large amount of heat energy, pushing the piston downward, making the crankshaft connecting rod mechanism run, and the flywheel at the rear end of the crankshaft transmits the power to the chassis transmission system to drive the car to drive.

2) Chassis: It is used to support the body and transmit the power from the engine to the driving wheels as needed to ensure that the car can run normally.

3) Body: The place where the driver works, but also the place where passengers are transported or goods are loaded. Generally, a sedan includes the front, body and tailgate; Trucks include the front of the car, the cab and the carriage (flathead cars only have the front and compartment), while passenger cars generally have only one body.

4) Electrical equipment: It is composed of power supply, engine starting system, ignition system (gasoline engine), lights, signals and instruments of the car. All electricity on the car is provided by generators and batteries.

1. The engine is the power unit of the automobile, and its function is to convert the heat energy generated by fuel combustion into mechanical energy output. Most automobile engines use reciprocating piston internal combustion engines, and the fuels used are mainly gasoline and diesel. The gasoline engine is generally composed of the body group, crank connecting rod mechanism, valve mechanism, fuel supply system, lubrication system, cooling system, ignition system, starting system, electronic control system and other parts.

Fueled by diesel. Engine, compression-ignition, non-ignition system.

2. The chassis is the main body of automobile assembly and driving, and its role is to support and install other assemblies and components such as the engine and body, form the overall shape of the car, and accept the power output of the engine, so that the car can move and ensure the normal driving of the car. The chassis is composed of four parts: transmission system, driving system, steering system and braking system.

The function of the transmission system is to transmit the power of the engine to the driving wheels through various transmission devices. The transmission system consists of a clutch, a transmission, a transmission shaft, and a drive axle.

The function of the driving system is to connect the various assemblies and components of the car into a whole, and play a supporting role in the whole car to ensure the normal driving of the car. The driving system consists of the frame, the front axle, the housing of the drive axle, the wheels, the suspension, etc.

The function of the steering system is to ensure that the car can drive in the direction selected by the driver, and is composed of a steering gear with a steering wheel and a steering transmission device.

The function of the braking system is to control the car, slow down or stop the car, and ensure that the car can be reliably parked after the driver leaves. The braking device of each automobile includes a number of independent braking systems, and each braking system is composed of an energy supply device, a control device, a transmission device and a brake.

3. The body is the place where the driver works, and it is also the place where passengers and goods are loaded. The body provides convenient operating conditions for the driver and a comfortable and safe environment for passengers or to keep the cargo intact. The body of cars and buses is generally an integral structure, and the body of a truck is generally composed of two parts: the cab and the cargo compartment.

4. The electrical equipment is composed of a power pack, an engine starting system and an ignition system, automotive lighting and signaling devices, etc. In addition, modern automobiles are increasingly equipped with various electronic devices, such as microprocessors, computer systems and various artificial intelligence devices (anti-lock braking systems, airbags, cruise control, positioning systems, etc.), which significantly improve the safety performance of automobiles.

A car is a non-track, unwired vehicle that is mainly driven by its own power and has 4 or more wheels. A car generally consists of four basic parts: engine, chassis, body, and electrical equipment.

Fuel vehicles are composed of four parts: engine, chassis, body, and electrical equipment.

Three major parts, body, chassis, powertrain.

Body system, powertrain, undercarriage, electrical system.

Brake system.

The car is made up of individual sheet metal parts.

The ignition method of diesel engine is compression-ignition, so there is no ignition system. Chassis The role of the chassis is to support and install the automobile engine and its various components and assemblies, form the overall shape of the car, and accept the power of the engine to make the car move.

The main parts of the car are composed of:

Motor. The engine is the power unit of the car, which is composed of 2 major mechanisms and 5 major systems: crank connecting rod mechanism, valve mechanism, cooling system, fuel supply system, lubrication system, ignition system, and starting system, but the diesel engine has one less ignition system than the gasoline engine.

1. Cooling system: generally composed of water tank, water pump, radiator, fan, thermostat, water temperature gauge and water discharge switch. There are two types of cooling for automobile engines, namely air cooling and water cooling. Generally, automobile engines are mostly cooled by water.
