What is the basic structure of the car? What is the basic structure of a car?

The basic structure of a car includes the engine, chassis, body, and electrical equipment, which are explained below:

1. Engine.

The engine is an important part of the car, it provides the power for the car to drive. At present, the main engines on the market are powered by gasoline or diesel, and the engine is composed of a crank connecting rod mechanism, a valve mechanism, a cooling system, a fuel supply system, and a lubrication starting system.

2. a chassis. The chassis is used to support and install body parts such as automobile engines to ensure that the car can run normally. The chassis is mainly composed of transmission system, driving system, steering system and braking system.

3. Body. The body is mounted on the chassis of the car and constitutes the shape of the car. It is mainly composed of fenders, cabin assemblies, engine cover assemblies, top cover assemblies, luggage compartment partition assemblies, trunk lid assemblies, rear quarter panels, side wall assemblies, floor assemblies, rear door assemblies and front door assemblies.

In addition, in terms of structure, the body is also divided into a load-bearing body and a non-load-bearing body, and the main difference is whether there is a rigid frame, that is, the "chassis girder".

4. Electrical equipment.

Electrical equipment is mainly composed of power supply and electrical equipment.

The basic structure of the car is as follows: Engine: The engine is divided into two major mechanisms and five major systems, including crank connecting rod mechanism, valve mechanism, oil supply system, cooling system, lubrication system, ignition system and starting system.

Chassis: The function of the chassis is to support and install the automobile engine and its component assembly, form the overall shape of the car, and accept the power of the engine to make the car move and ensure normal driving. The chassis consists of four parts:

Drivetrain, drive, steering, and braking systems. Body: The body is mounted on the frame of the chassis for the driver and passengers to ride or load cargo.

Electrical equipment: Electrical equipment consists of a power supply and electrical equipment. including power supply, storage batteries and generators; Electrical equipment includes engine starting systems, gasoline engine ignition systems, and other electrical equipment.

The car is generally composed of four basic parts: the body, the powertrain (engine, transmission), the chassis and the electronic and electrical equipment. The car body includes windows, doors, cockpit, passenger compartment, engine compartment and luggage compartment, among others.

The shape of the body is divided into van type, fish type, boat type, streamline type and wedge type, and the structural form is divided into single box, hatchback and sedan type. Body parts are further divided into covering parts and structural parts. Covering parts refer to body shells, doors, glass, seat decorations, etc.; Structural parts are the basic parts, the chassis of the body, the girders, the vertical and horizontal bars, etc.

The powertrain refers to the combination of four parts of the transmission system, the driving system, the steering system and the brake system on the car, which supports and installs the automobile engine and its various components and assemblies to form the overall shape of the car, bear the engine power, and ensure normal driving.

Electrical and electronic equipment:

1. The power supply system includes a battery, a generator and a regulator. The generator supplies power to the electrical equipment of the whole vehicle and charges the battery at the same time. The role of the regulator is to keep the output voltage of the generator constant.

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.

2. Lubrication system: The engine lubrication system is composed of oil pump, filter, oil filter, oil channel, pressure limiting valve, oil gauge, pressure plug and dipstick.

3 Fuel Supply System:

7. Valve mechanism: cylinder head, valve chamber cover camshaft, valve intake manifold, exhaust manifold, air filter, muffler, three-way catalytic supercharger, etc.

Chassis. The chassis consists of a drivetrain, a driving train, a steering system, and a brake system.

The role of the chassis is to support and install the assembly of the automobile engine and its various parts, 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 consists of five parts: transmission system, driving system, steering system, suspension system and brake system. Remember!

An engine is a complex machine that consists of many mechanisms and systems. Whether it is a gasoline engine, or a diesel engine; Whether it's a four-stroke engine or a two-stroke engine; Whether it's a single-cylinder engine, or a multi-cylinder engine. In order to complete the energy conversion, realize the work cycle, and ensure the continuous normal operation for a long time, the following mechanisms and systems must be in place.

1) Crank linkage mechanism.

The crank linkage mechanism is the main moving part of the engine to realize the working cycle and complete the energy conversion. It is composed of a body group, a piston connecting rod group and a crankshaft flywheel group, etc. In the power stroke, the piston is subjected to gas pressure in a linear motion in the cylinder, which is converted into the rotary motion of the crankshaft through the connecting rod, and outputs power from the crankshaft.

During the intake, compression and exhaust strokes, the flywheel releases energy and converts the rotational motion of the crankshaft into the linear motion of the piston.

2) Gas distribution mechanism.

The function of the valve mechanism is to open and close the intake and exhaust valves at regular intervals according to the working sequence and working process of the engine, so that the combustible mixture or air enters the cylinder, and the exhaust gas is discharged from the cylinder to realize the ventilation process. Most of the valve trains adopt overhead valve valve mechanisms, which are generally composed of valve groups, valve transmission groups and valve actuation groups.

3) Fuel supply system.

The function of the fuel supply system of the gasoline engine is to prepare a certain amount and concentration of mixed gas according to the requirements of the engine, supply it to the cylinder, and discharge the exhaust gas after combustion from the cylinder to the atmosphere; The function of the diesel engine fuel supply system is to supply diesel and air into the cylinder respectively, form a mixture in the combustion chamber and burn it, and finally discharge the exhaust gas after combustion.

4) Lubrication system.

The function of the lubrication system is to deliver a certain amount of clean lubricating oil to the surface of the parts in relative motion to achieve liquid friction, reduce frictional resistance, and reduce the wear of parts. and the surface of the part is cleaned and cooled. The lubrication system usually consists of a lubricating oil channel, an oil pump, an oil filter, and some valves.

5) Cooling system.

The function of the cooling system is to dissipate part of the heat absorbed by the heated parts in time to ensure that the engine works at the most suitable temperature state. The cooling system of a water-cooled engine usually consists of a cooling jacket, a water pump, a fan, a water tank, a thermostat, etc.

6) Ignition system.

In a gasoline engine, the flammable mixture in the cylinder is ignited by an electric spark, for which a spark plug is installed on the cylinder head of the gasoline engine, and the head of the spark plug protrudes into the combustion chamber. All equipment that can generate electric sparks between the spark plug electrodes on time is called an ignition system, which usually consists of a battery, a generator, a distributor, an ignition coil and a spark plug.

7) Starting system.

In order to make the engine transition from a stationary state to a working state, it is necessary to rotate the crankshaft of the engine with external force first, so that the piston can reciprocate, and the combustible mixture in the cylinder burns and expands to work, and pushes the piston to move downward to rotate the crankshaft. The engine can run on its own and the duty cycle can be automatic. Therefore, the whole process from the crankshaft starting to rotate under the action of external force to the engine starting to idle automatically is called the starting of the engine.

The device required to complete the starting process is called the starting system of the engine.

The role of the engine is to make the fuel supplied to it burn and generate power. Most automobiles use a reciprocating piston internal combustion engine, which is generally composed of a body, a crank connecting rod mechanism, a valve mechanism, a supply system, a cooling system, a lubrication system, an ignition system (used in gasoline engines), a starting system and other parts.

Power system, power system, brake system, oil circuit, heat dissipation, etc.

What are the parts of a carThe car is usually composed of four parts: engine, chassis, body, and electrical equipment. The role of the engine is to make the fuel supplied to it burn and generate power. Most automobiles use reciprocating piston internal combustion engine (due to the rapid development of modern science and technology, automobile engines in addition to internal combustion engines, there are fuel cell engines, battery motors, etc., we will introduce in the new technology in the future), it is generally composed of the body, crank connecting rod mechanism, gas distribution mechanism, supply system, cooling system, lubrication system, ignition system (used in gasoline engines), starting system and other parts.

The chassis receives the power of the engine, makes the car move, and ensures that the car runs normally according to the driver's control. The chassis is made up of the following parts: Drive train – which transmits the power of the engine to the driving wheels.

It includes components such as clutch, transmission, transmission shaft, and drive axle.

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. No matter what kind of car is good, the basic knot source comma is the same.

It's just that the materials used and the electronic devices are different.

The engine is the most important component, and the engine parameters such as displacement, torque and horsepower are largely determined by the engine.

The gasoline engine is composed of two mechanisms and five major systems, the mechanism is the crank connecting rod mechanism and the valve mechanism, and the system is the ignition system, the starting system, the supply system, the lubrication and cooling system. Diesel engines do not have an ignition system because of firewood.

The oil engine is compression-ignited and does not require a spark plug and ignition coil.

The chassis is equivalent to the skeleton of the body, which is mainly composed of the drive train, the driving system, and the steering system.

and braking system. The drive train is the conveyor belt of power transmission, which mainly transmits the power of the engine to the wheels, and the main components are transmission, transmission shaft, differential and final reducer.

The drivetrain is a very important system, which can play a role in the smoothness of the power combination, for example, some cars use dual-clutch transmission.

Speedloaf, then the frustration when changing gears will be better than that of the manual automatic transmission.

and continuously variable transmissions will be larger, but each has its own advantages.

This part of the body mainly includes parts like sheet metal and painting, depending on the vehicle makes.

The materials used, some cars use a little better materials, then its sheet metal materials.

Definitely enough. In terms of painting, the German car will be better than other cars, and the paint will be a little thicker.

Automotive electrical equipment mainly includes such as electrical systems and starting systems.

The circuit part includes like some air conditioning systems and some say Shu.

Suitable systems are all yes. Electrical equipment, basically every car will be equipped with basic, but the more expensive the car, the more complex and advanced the electrical equipment will be, this is where the car is most expensive.
