How many parts of the car are made? What are the main components of a car?

A car usually consists of four parts: engine, chassis, body, and electrical (electronic) equipment.

1.The engine is the power plant of the car, and its function is to make the fuel supplied into it burn and generate power.

Generally, automobiles use reciprocating piston internal combustion engines. It is composed of a body and crank connecting rod mechanism, a valve mechanism, a fuel supply system, a cooling system, a lubrication system, an ignition system (gasoline engine) and a starting system.

2.Chassis: It consists of a drive train, a driving system, a steering system and a brake system.

1) Drive train: It is to receive the power of the engine and transmit it to the driving wheels. It includes: clutch, transmission, universal transmission and drive axle, etc.

2) Driving system: It is to install the general name and components of the car in the appropriate position, and play a supporting role in the whole car to ensure the normal driving of the car. It includes: frames, axles, suspensions, wheels, etc.

3) Steering system: It is to make the car drive in the direction given by the driver. It includes: steering gear, steering transmission mechanism, and some cars also have power steering.

4) brake system: is for the car to slow down or stop, and ensure that the driver still reliably stays in place after leaving the car, it includes: brake and brake transmission mechanism.

3.Body: It is a device that forms the riding space of the driver and passengers, and is also a tool for storing luggage and other items.

4.Electrical equipment: It is an important part of the automobile, which is composed of power supply, engine ignition system (gasoline engine) and starting system, lighting and signal equipment, air conditioning instrumentation and alarm system, and auxiliary electrical appliances.

A car consists of four basic parts: engine, chassis, body, and electrical equipment.

An engine is a machine that can convert other forms of energy into mechanical energy, such as internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc.

The chassis 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.

The body refers to the part of the vehicle that is used to carry people and goods, and also refers to the vehicle as a whole. The body of some vehicles is both the driver's workplace and the place to accommodate passengers and goods. The body includes windows, doors, cockpit, passenger compartment, engine compartment and luggage compartment, among others.

Electrical equipment is a general term for generators, transformers, power lines, circuit breakers and other equipment in the power system.

The chassis of the car:

Transmission train: It is mainly composed of clutch, transmission, universal joint, transmission shaft and drive axle.

Clutch: Its function is to make the power of the engine and the transmission device smoothly engaged or temporarily separated, so as to facilitate the driver to start, stop, shift and other operations of the car.

Transmission: It is composed of transmission shell, transmission cover, first shaft, second shaft, intermediate shaft, reverse shaft, gear, bearing, control mechanism and other parts, which are used for automobile transmission and variable output torque.

Driving system: It is composed of the frame, axle, suspension and wheels. Its basic function is to support the quality of the whole car and ensure the driving of the car.

Leaf Springs & Shock Absorbers: The role of leaf springs is to maintain an elastic connection between the frame and body and the wheels or axles. The function of the shock absorber is to cushion the vibration when the car is subjected to vibration impact. The shock absorber is used in parallel with the leaf springs.

Steering system: It is composed of steering wheel, steering gear, steering knuckle, knuckle arm, tie rod, straight tie rod, etc., and its function is steering.

Front wheel alignment: In order to keep the car stable and straight, the steering is light, and the wear and tear of the tires and steering parts of the car in the driving process is reduced, the installation between the front wheel, the steering kingpin and the front axle has a certain relative position, which is called "front wheel alignment". It includes kingpin tilt, production and sales tilt, and front wheel toe.

The toe-in value is the difference between the distance between the front edges of the two front wheels and the distance between the rear edges.

Hand brake: Hand brake is a device that makes the car not slippery when parked, and in special cases, with the foot brake.

2. The chassis of the car: the chassis is to support and install the engine of the car and its various parts 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. Automobile body: The body is installed on the frame of the chassis for drivers and passengers to ride or load goods. 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 is composed 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.

A car is mainly composed of four parts: the engine, the chassis, the electrical equipment and the body.

The main components of the car are mainly the engine and gearbox of the car, but the box also has the tires of the car and the sensors of the car. There is also the transmission system of the car, which is composed of these parts in the main car.

The main components of the car should be the engine, as well as the tire cab, which are the main components.

Four major components: engine, chassis, body, electrical equipment.

The engine is the power plant of the car.

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.

It can be simply divided into: chassis, engine, gearbox, and other accessories.

The chassis is actually called the body structure. Because the vast majority of the current family cars are full-load structures, and there is no separate "girder frame", the entire body structure is a force system.

The engine is the heart of the car, providing the power source for the car to run forward. It is the basic power guarantee for the driving of the car. Without the engine, the car won't move.

The gearbox is used to match the engine and wheels. The existence of the gearbox solves the needs of various different working conditions of the car for starting, acceleration and high-speed driving.

Other accessories include wheels, steering machines, and other devices and equipment. They are all an indispensable part of the car.

A car generally consists of four basic parts: engine, chassis, body, and electrical equipment. The engine is the device that provides power for the operation of the 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.
