What does the active part of the clutch consist of?

The clutch is composed of four parts: the active part, the driven part, the pressing part and the control mechanism. Each section is structured in detail as follows:

1. Active part: flywheel, pressure plate, clutch cover, etc.

2. The driven part: driven disk, driven shaft, etc.

3. Compression part: only one part of the compression spring.

4. Control mechanism: respectively release lever, release lever support column, swing pin, release sleeve, release bearing, clutch pedal, etc.

Flywheel. Clutch cover.

pressure plate and other parts.

Flywheel. Clutch cover.

pressure plates and other components.

First, the composition of the clutch.

The clutch is composed of a transmission steel belt, a pressure plate, a flywheel, a crankshaft, a driven disc, a front support ring, a rear support ring, a release hook, a release bearing, a gearbox input shaft, a clutch cover, a diaphragm spring, etc.

The clutch is located in the flywheel housing between the engine and the gearbox, and the clutch assembly is fixed to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the gearbox. While the car is moving, the driver can press or release the clutch pedal as needed to temporarily separate and gradually engage the engine from the gearbox to cut off or transmit the power input from the engine to the transmission.

The clutch is a common component in mechanical transmissions, allowing the transmission system to be disengaged or engaged at any time. The basic requirements are: smooth jointing, rapid and thorough separation; Easy to adjust and repair; Small overall dimensions; Small mass; Good wear resistance and sufficient heat dissipation capacity; The operation is convenient and labor-saving, and the commonly used ones are divided into two categories: tooth inlay type and friction type.

Second, the role of the clutch.

1. Ensure a smooth start of the car.

The car is in a stationary state before starting, if the engine and the gearbox are rigidly connected, once the gear is hooked, the car will suddenly rush forward due to the sudden connection of power, which will not only cause damage to the parts, but also the driving force is not enough to overcome the huge inertia generated by the forward rush of the car, so that the engine speed drops sharply and stalls.

2. Easy to shift.

When the car is driving, it often switches to different gearboxes to adapt to changing driving conditions. If there is no clutch to temporarily separate the engine from the gearbox, the meshing force transmission gears in the gearbox will be difficult to separate because the load is not removed, and the pressure between the meshing tooth surfaces is very high.

3. Prevent the transmission system from overloading.

When the car brakes urgently, the wheels suddenly and sharply reduce speed, and the drive train connected to the engine still maintains the original speed due to the inertia of rotation, which often produces a moment of inertia in the transmission system that is much greater than the engine torque, making the parts of the drive train easy to damage.

Because the clutch relies on friction to transmit torque, when the load in the drive train exceeds the torque that can be transmitted by friction, the main and driven parts of the clutch will automatically slip, thus preventing the drive train from overloading.

4. Reduce torsional vibration impact.

The working principle of an automobile engine determines the unevenness of its output torque. In the power stroke, the combustion chamber gas** produces a great impact torque, while in other strokes, it is the inertial back-dragging engine.

The clutch is mainly composed of an active part, a driven part, a pressing device and a control mechanism. The active part is composed of a flywheel, a pressure plate, a clutch cover, etc., the driven part is composed of a driven disc and a driven shaft, the hold-down device is mainly composed of a plurality of compression springs, and the control mechanism is mainly composed of a pedal, a pedal pull rod, a separating fork, a separating sleeve and a separating bearing and a separating lever.

The working condition of the clutch is as follows: when the clutch pedal is stepped on, the force pushes the inner end of the separation fork to move forward through the pedal lever, forces the inner end of the release lever to move forward, and the outer end pulls the pressure plate to compress the compression spring and moves back, so that the driven disc loses pressure and disengages from the flywheel, and cuts off the power transmission between the engine and the drive train, as shown in Figure 3-14a. When the clutch pedal is lifted, the pedal, the release fork and the release bearing return to the original position under the action of their respective return springs, at this time, the compression spring is extended, the pressure plate is pushed forward, and the driven disc is pressed on the flywheel again, so that the power of the engine is transmitted to the driven disc through the flywheel and the pressure plate, and then transmitted to the first shaft of the transmission by the driven disk, as shown in Figure 3-14b.

The clutch is located between the flywheel and the transmission, and its main function is to engage or disengage the engine from the transmission device in order to carry out the car starting, shifting, stopping and other operations, and can prevent the drive train from overloading.

The clutch of a manual transmission in a car is installed between the engine and the transmission. The clutch is composed of five parts, namely the clutch pressure plate, the clutch plate, the release bearing, the release fork, the clutch pin pull cable or the clutch cylinder. It allows the engine and gearbox to be fully connected and separated from each other.

Its components are divided into five parts:

Active components: flywheel, clutch and pressure plate.

This part is connected to the penitent motive crankshaft. The clutch cover is bolted to the flywheel. When using a pressure plate clutch, torque is transmitted by three or four drive discs.

Driven part: driven disc, output shaft (also variable speed input shaft).

The part consists of a double plate and multiple driven discs, which transmit power from the active parts to the input shaft of the transmission through friction.

Compression mechanism: compression spring (diaphragm clutch is diaphragm spring.) The circumferential clutch is a coil spring).

This part is mainly composed of coil springs and diaphragm springs. He spun with the active part of the hungry swim. Leaning against the clutch cover, he pressed the pressure plate onto the flywheel, thus pressing the follower disc between the flywheel and the pressure plate.

Control mechanism: clutch pedal, release lever, release fork, release bearing, release sleeve, etc.

The structure of the automobile clutch is complex, because they do not understand the professional knowledge, many car owners do not know the structure of the clutch, so what does the active part of the clutch include?

The active part of the clutch is the flywheel, the distraction and the pressure plate, these three parts are connected with the crankshaft of the engine, the clutch cover is bolted to the flywheel, and the pressure plate and clutch rely on three to four transmission plates to transmit torque. The driven part of the clutch is the moving disc and output shaft, and the driven part transmits the power transmitted from the active part to the input shaft of the transmission. The active part and the driven part can be separated, and can be simply engaged, and will rotate relative to each other during the transmission process.

After understanding the structure of the active part and the driven part of the clutch, we can better understand the working principle of the clutch. In the future, when using the clutch, avoid using the clutch by mistake, and do not use the clutch violently, which will not only hurt the clutch, but also hurt the transmission of the car, causing unnecessary economic losses.
