What are the functions of each component of the transmission system?

The functions of each component of the transmission system are as follows:

1) Clutch.

Smooth gear changes are guaranteed and power transmission is interrupted if necessary.

2) Transmission.

Variable speed, torque change, direction change and interrupt power transmission.

3) Universal transmission device: realize the power transmission between two shafts with angles and frequent changes in relative positions.

4) Final reducer: transmits power to the differential.

And to reduce the speed and increase the torque, change the direction of transmission.

5) Differential: Transmits power to the half shaft and allows the left and right half shafts to rotate at different speeds.

6) Half shaft: transmits the power of the differential to the driving wheels.

For front-wheel drive cars, the torque emitted by the engine passes through the clutch and then the gearbox.

Universal joints, transmission shafts.

The final reducer, differential, and half shaft are transmitted to the rear wheels, so the rear wheels are also called drive wheels.

The torque obtained by the driving wheel gives a backward force to the ground, and thus the ground produces a forward reaction force to the driving wheel.

This reaction force is the driving force of the car. The front wheels of the car generally have no direct connection with the drive train, so they are called driven wheels.

The composition and arrangement of the drive train varies depending on the type of engine, the location of the installation, and the purpose of the car. For example, off-road vehicles mostly use four-wheel drive, so an assembly such as a transfer case is added to its drive train. For front-wheel drive vehicles, there are no transmission shafts and other devices in its drive train.

The transmission system is generally composed of a clutch, a transmission, a universal transmission, a final reducer, a differential and a half shaft.

Its basic function is to transmit the power emitted by the engine to the driving wheels of the car, generating driving force so that the car can drive at a certain speed.

For front-mounted and rear-wheel drive cars, the torque emitted by the engine is transmitted to the rear wheels through the clutch, gearbox, universal joint, transmission shaft, final reducer, differential, and half shaft, so the rear wheels are also called drive wheels. The driving wheel gets torque and gives the ground a backward force, and thus causes the ground to produce a forward reaction force on the driving wheel, which is the driving force of the car. The front wheels of the car generally have no direct power connection with the drive train, so they are called driven wheels.

The transmission system is composed of the transmission part, the control part and the corresponding auxiliary part, and the transmission part is composed of various transmission elements or components, shafts and shafts, braking, clutching, reversing and energy storage elements, and only reaches the drive wheel after a series of power transmission equipment, so as to realize the transmission of power and movement.

The control part is operated by a control device with functions such as starting, clutching, braking, speed regulation, and reversing by manual or electric means to change the working state and parameters of the power engine or transmission system, so that the actuator can maintain or change its motion and force. The auxiliary part is a device designed to ensure the normal operation of the transmission system, improve the working conditions and prolong the service life. Such as:

Cooling, lubrication, counting, lighting, silencing, shockproofing and dust removal devices.

The transmission system is composed of a transmission part, a control part and a corresponding auxiliary part.

The mechanical transmission system is generally composed of a clutch, a transmission, a universal transmission device (universal joint and transmission shaft), a drive axle (final reducer, differential and half shaft), etc.

The transmission system is mainly composed of power unit, transmission components, transmission accessories, execution components, etc.! Among them, the transmission element is mainly composed of rack and pinion, worm gear and worm, screw rod, oil cylinder, etc.; The power unit is mainly composed of motors, hydraulic motors, etc.; The main accessories are mainly composed of bearings, nut seats, etc.

Drivetrain system (also known as drivetrain system) is the power system that enables the car to generate driving force, including the final transmission, axle box, bearings, gears and bogies, and so on. A good drivetrain not only allows for deviations when evaluating the gearing of the final drive gearset, but also takes into account deviations in the axle or bogie frame.

It is composed of clutch, transmission, universal transmission, final reducer, differential and half shaft, etc. Its function is to transmit the power emitted by the engine to the driving wheels of the car, generating driving force so that the car can drive at a certain speed.

The drivetrain transmits the power generated by the engine to the wheels.

The drivetrain includes a gearbox.

Half shafts, transmission shafts.

Differentials, final drives, etc. The transmission system transmits power to the wheels and plays a role in reducing speed and increasing torque.

Because the engine speed is very high, the crankshaft.

The revs are high, but there is not enough torque to drag the car if the revs are too high. Therefore, the transmission system will use different gear ratios to reduce the speed and increase the torque, so that the car can start and climb normally. And the transmission system can adapt to the power needs of the car under any working conditions through different gear combinations.

The transmission system is composed of a clutch, a transmission, a universal transmission, a final reducer, a differential and a half shaft, etc.

The basic function is to transmit the power emitted by the engine to the driving wheels of the car, generating driving force so that the car can drive at a certain speed. It can be divided into two main categories:

1. Friction transmission that transmits power and movement by friction between parts, including belt transmission, rope transmission and friction wheel transmission;

2. Meshing transmission that relies on the meshing of the driving parts and the follower or the meshing of middleware to transmit power or motion, including gear transmission, chain transmission, spiral transmission and harmonic transmission.

Mechanical transmission can be divided into friction transmission, chain transmission, gear transmission, belt transmission, turbine vortex transmission, ratchet transmission, crankshaft connecting rod transmission, pneumatic transmission, hydraulic transmission, universal joint transmission, steel wire cable transmission, coupling transmission, spline transmission.

The transmission system is mainly composed of a gearbox. Transmission shaft. Cross Street. Half shaft. Final reducer. Differential. bearings and so on.

Discharge cooling is another type of convection cooling. Unlike regenerative cooling, the coolant used for exhaust cooling absorbs heat to the thrust chamber and is discharged out of the combustion chamber instead of entering the combustion chamber to participate in combustion. Direct drain coolant reduces the thrust chamber specific impulse, so the coolant flow for drain cooling needs to be minimized while only using drain cooling at the outlet section of the nozzle that is relatively less heated.

There is also radiative cooling, in which the heat flow is transferred from the combustion products to the thrust chamber, and then the heat is radiated by the thrust chamber wall to the surrounding space. Radiative cooling is characterized by simplicity and small structural mass. It is mainly used in the extension section of large nozzles and the thrust chamber of small thrust engines using high-temperature resistant materials.

When cooling in the thrust chamber of the tissue, a relatively low temperature liquid or gas protective layer is established on the surface of the thrust chamber wall to reduce the heat flow to the thrust chamber wall, reduce the wall temperature, and achieve cooling. Internal cooling is mainly divided into three methods: internal cooling (shield cooling), membrane cooling and diaphoretic cooling of head tissues. After the internal cooling measures are adopted in the thrust chamber, the mixing ratio near the wall of the combustion chamber is different from the optimal mixing ratio in the central area (in most cases, the near-wall layer rich in fuel is used) due to the need to reduce the temperature of the protective layer, resulting in the uneven distribution of the mixing ratio along the cross-section of the combustion chamber, so that the combustion efficiency is reduced to a certain extent.

Membrane cooling is similar to shield cooling in that it cools the thrust chamber wall by establishing a uniform and stable coolant film or air film protective layer near the inner wall surface, except that the coolant used to establish the protective layer is not injected by the injector, but is supplied through a special cooling belt. The cooling band is generally arranged in a cross-section of the combustion chamber or the convergence section of the nozzle. There can be several cooling bands along the length of the combustion chamber.

In order to improve the stability of the membrane, the coolant often flows through the gaps or small holes in the cooling belts, and when sweating is used, the thrust chamber wall or part of the inner wall is made of porous material with a pore diameter of tens of microns. Porous materials are usually sintered with metal powders or pressed with metal mesh. In this case, the number of pores per unit area is increased by making the micropores in the material as evenly distributed as possible.

The liquid coolant penetrates into the inner wall, creating a protective film that reduces the density of the heat transferred to the wall. When the flow rate of liquid coolant used for sweat cooling is above a certain threshold, a liquid film is formed near the wall of the thrust chamber. When the coolant flow rate is below the critical flow, the inner wall temperature will be higher than the coolant boiling point at the current pressure, and some or all of the coolant will evaporate, forming an air film.

In addition to the above thermal protection, there are other thermal protection methods such as: ablation cooling, thermal insulation cooling, hot melt cooling and composite protection of chamber walls. 3. Thermal protection scheme of high enthalpy gas generator Based on the above methods and the actual situation, the thermal protection method of high enthalpy gas generator is obtained.

The combustion chamber of a high-enthalpy gas generator differs from that of a liquid rocket engine, eliminating the front thrust chamber part, making its structure simpler and more effective. Then, the thermal protection involved is the thermal protection part of the combustion chamber wall. As the fuel enters the combustion chamber, it quickly decomposes and releases large quantities.

The transmission system has the following functions: 1. Ensure the normal driving of the car: as the function of deceleration, speed change, reversing, interruption of power, inter-wheel differential and inter-axle differential of the drive train, and cooperate with the power given by the engine, so as to ensure the normal driving of the car under various working conditions, and also have good power and fuel economy for the car.

2. Interrupt the power transmission: the power of the body should be disconnected at the start, and when changing gears and emergency braking, the impact on the owner must be reduced, and the power must be disconnected, which is the role of the drive system.

Composition of transmission system: 1. Transmission mechanism: manual transmission mechanism and automatic transmission mechanism; 2. Differential:

It is a tool to solve the problem of different rotational speeds on the left and right; 3. Lead imitation of the transmission shaft: the power transmitted through the transmission system is transmitted to the differential and then buried in the mechanism that generates the driving force; 4. Engine configuration: front-engine front-wheel drive, front-engine rear-wheel drive, mid-engine rear-wheel drive.

The function of the transmission system is to transmit the power emitted by the engine to the driving wheels of the car, generating driving force so that the car can drive at a certain speed. The drive train is divided into the following according to the arrangement

The front bend is aggressively rear-wheel-drive, rear-wheel drive, front-wheel drive, and all-wheel drive.

The traditional system is mainly composed of clutch, transmission, universal transmission, final reducer, differential and half shaft. It consists of a clutch, a transmission, a universal transmission, a main trouser speeder, a differential, and a half-shaft. Its function is to transmit the power of the engine to the wheels of the car to generate driving force, so that the car can drive at a certain speed.

The following is the relevant introduction: 1. Decelerate or increase the speed of power machinery to reduce or increase the speed of power machinery to meet the needs of system implementation. 2. Variable speed, when it is uneconomical, impossible or impossible to meet the requirements of speed transmission by using power machinery, the variable speed is graded or stepless through the transmission system to meet the various speed requirements of the execution system.

3. Change the law of motion or the form of movement, and transform the continuous rotation motion of uniform vertical width speed output by the power engine into a rotating or non-rotating motion that changes according to a certain law.
