Color illustration of the structure and principle of automobile

< p>Body structure The body of a car is composed of several plates. The body structure of a car can be divided into three types: steel body, aluminum body and carbon fiber body.

First of all, the air intake of the turbine chamber is connected to the engine exhaust manifold, and the exhaust port is connected to the exhaust pipe. Then the intake port of the supercharger is connected to the air filter pipe, and the exhaust port is connected to the intake manifold. Finally, the turbine and impeller are installed in the turbine chamber and the supercharger respectively, and the two are connected rigidly.

A car usually consists of four parts: engine, chassis, body and electrical equipment. The power generated by the engine is transmitted to the drive wheel through the clutch, transmission, universal drive shaft and differential to drive the car. The following are illustrations of four parts of the car, so that you can better understand the composition and structure of the car.

Car composition A car is a non-track frameless vehicle that is mainly driven by its own power and has 4 or more wheels. Cars are generally composed of four basic parts: engine, chassis, body and electrical equipment.Engine After the body is removed, we can find the heart of the car - the engine at a glance.

The overall structure of a car consists of four parts: engine, chassis, body and electrical equipment. Engine. It is a power device of a car. Its function is to convert the fuel entering it into heat energy after combustion, and convert it into kinetic energy, and drive the car through the transmission system of the chassis. Chassis.

- The body is installed on the chassis frame for drivers and passengers to ride and load goods. The body of a car and a passenger car is generally an integral structure, and the body of a truck is generally composed of two parts: the cab and a trunk. Electrical equipment - Electrical equipment consists of two major parts: power supply and electrical equipment. The power supply includes batteries and generators.

An animation is fully understood, intuitive automobile mechanical principle

1. First of all, the intake of the turbine chamber is connected to the engine exhaust manifold, and the exhaust port is connected to On the exhaust pipe. Then the intake port of the supercharger is connected to the air filter pipe, and the exhaust port is connected to the intake manifold. Finally, the turbine and impeller are installed in the turbine chamber and the supercharger respectively, and the two are rigidly connected.

2. The working principle of the four-stroke gasoline engine is to mix air and gasoline in a certain proportion into a good mixture. In the intake stroke, it is sucked into the cylinder. The mixture is compressed and ignited to produce heat energy. The high-temperature and high-pressure gas acts on the top of the piston, pushing the piston to make a reciprocating linear motion, through the connection The rod and crankshaft flywheel mechanism output mechanical energy to the outside world.

3. As shown in the figure below, the timing mark of the liberation CA6102 engine is "up stop point/1~6". When this mark is right with the line on the flywheel shell, it means that the piston of 1~6 cylinders is at the upper stop point position.

4. It is mainly composed of universal joint, transmission shaft and intermediate support. When installing, the universal joints at both ends of the drive shaft must be in the same plane. The universal joint is the universal joint, which is real.The machine part of the variable angle power transmission is used to change the position of the direction of the transmission axis. It is the "joint" part of the universal transmission device of the automobile drive system.

5. There are three versions of the principle of Muniu Liuma, which are introduced as follows: Muniu Liuma is an ordinary unicycle cart.

6. Four-connection rod, bicycle shock absorption system, using the principle of bar to solve the shock-absorbing spring force problem of ordinary direct-connected shock-absorbing system, so that the shock-absorbing spring is vertical and the friction of the fixed shaft is minimized. It is a simple shock-absorbing system solution technical solution.

What is the schematic diagram of car shift

1. There are manual transmission and automatic transmission. The manual transmission is to control the vehicle according to the gear position in the gearbox, that is, the big wheel has a small wheel, the car runs fast, the small wheel turns around, and the big wheel is still turning.The automatic transmission adds the electronic valve control principle.

2. It can be seen from the above figure that if the blue gear rotates once, it can drive the green gear to rotate twice. The same input power, the car is faster. The force point is at the left end of the red arrow, and the contrast 1 can be seen. The red double arrow arms need to be short at that time. Under a given torque, the speed is faster, but the driving force of the vehicle is reduced.

3. The car gear is mainly composed of clutch, gear and drive shaft. The car engine is connected to the transmission through the clutch. When the clutch pedal is lifted, the power of the engine can be transmitted to the transmission.

4. Manual transmission reverse principle Manual transmission: The working principle is to change the torque and speed of the drive wheel through the shift lever, switching the active gear on the middle shaft, and the combination of gears of different sizes and the power output shaft.The following figure is a simplified structure diagram of a manual transmission (2 gears).

5. But if there is no synchronizer (purple), the two gears (blue) can only rotate over the power output shaft (that is, it will not drive the output shaft to rotate). In the figure, the synchronizer is located in the middle state, which is equivalent to the transmission in neutral gear.

6. The working principle of manual transmission The working principle of manual transmission is to change the torque and speed of the drive wheel by moving the transmission lever, switching the active gear on the intermediate shaft, and combining it with the power output shaft by combining gears of different sizes. Let's take a look at the construction diagram of the simplified manual transmission (2 gears).
