What are the Types of Clutch?

Clutch is usually used on a motor vehicle. As a mechanical transmission part, it’s used to cut or transmit the power produced by the engine. Generally speaking, it’s a pedal to control the vehicle speed. The clutch can be divided into four types: electromagnetic clutch, magnetic powder clutch, friction clutch and hydraulic clutch. They will be introduced in detail next.

Electromagnetic clutch‍‍
Any clutch can complete the function of mechanical transmission, electromagnetic clutch controls the engagement and separation of the clutch through the power failure of the coil. For the common dry monolithic electromagnetic clutch, when the coil is powered on, magnetic force is generated to pull the “armature” piece, so that the clutch is engaged; When the coil is powered off, the magnetic force disappears and the “armature” returns back, the clutch is separated. This is a power failure working mode, beside this, the electromagnetic clutch can also work in power break combination, which will not be introduced here.

Magnetic powder clutch‍‍
Place magnetic powder between the driving part and driven part of the magnetic powder clutch, the magnetic powder combines as powering on and promotes the driving part and driven part to rotate together; As the power is off, the magnetic powder doesn’t combine, the driving part and driven part are separated. Magnetic powder clutch is suitable for mechanical transmission system with high frequency action. It can engage or separate the driving part and driven part when the driving part is running, so as to complete the transmission.

Friction clutch‍‍
Friction clutch mainly consists of four parts: driving part, driven part, compressing mechanism and control mechanism. Among, the control mechanism is used to separate the clutch, three other parts are used to ensure that the clutch can carry out power transmission in the engagement condition. When stepping on the clutch, remove the free clearance first in the free stroke and then generate the separation gap in the working stroke to separate the clutch; When loosening the clutch, eliminate the separation gap first and then generate the free clearance to engage the clutch. Friction clutch is the longest and most widely used clutch.

Hydraulic clutch
Hydraulic clutch mainly consists of three parts: input shaft, working fluid tank and output shaft. Among, input shaft mainly includes the speed increasing gear train; the working fluid tank consists of impeller, driven wheel and impeller housing; output shaft mainly includes the driven wheel. The biggest difference between hydraulic clutch and mechanical clutch is that it takes fluid as the transmission medium, therefore, the transmission characteristics are also different from that of mechanical clutch.
