Clutch in car

The clutch is designed to briefly decouple the engine and transmission during gear shifts and aid in smooth starting. If we consider directly the disc clutch mechanism itself, then its work is carried out due to the friction forces that appear between the contacting surfaces.

The clutch discs themselves are of two types: leading, that is, with a flywheel, and driven, that is, those with which the YuMZ clutch is connected. The design of the clutch itself varies depending on the number of clutch discs, which can be either one or two.

There are three main types of clutch: mechanical, hydraulic and electromagnetic.

Today, not many cars are equipped with an electromagnetic clutch or ETM clutch. In general, electromagnetic clutches have a very wide range of applications, but due to the complexity of their design, they have not received much use in cars. So, ETM couplings are quite often used in the mechanism of metal-cutting machines and other industrialmachines. Naturally, they have found the widest application in gearboxes. Advantages of electromagnetic clutches:

• protect against overloads (both engine and machine);
• keep the previous torque value;
• due to slip discs soften shocks and bumps.

This clutch has the following significant advantages:

• guaranteed quick start mechanisms with load;
• idling losses are significantly reduced, which normalizes the thermal balance of the operated device;
• protects the mechanism from impulsive loading.

Specifically, in cars, either mechanical or hydraulic clutches are most often used. Depending on the type of vehicle. For example, hydraulic couplings are mainly installed on tractors and other agricultural machinery.

This clutch has the following advantages:

• kinetic energy of fluid;
• low percentage of wear parts, smooth start;
• high efficiency and smooth damping of all shock loads.

Also these clutches can be dry or oil, single or double disc, closed or open.

If the clutch has certain malfunctions, then it becomes impossible to change gear smoothly, therefore, the normal start of the car is excluded. Clutches can also be distinguished by pressing force: with a central or with a peripheral spring,respectively, there is a semi-centrifugal or centrifugal clutch.

A conventional clutch usually consists of the following parts: flywheel, clutch release fork, central pressure spring and transmission input shaft, clutch cover bolt, driven plate, pressure plate, clutch housing, clutch release, casing clutch. But for different types of cars, and, in general, for different types of machines and machine tools, the clutch is made in different ways and can have a fundamentally different structure.
