What are the classifications of clutch operation?
1 Answers
According to the type of transmission device used to disengage the clutch, clutch operating mechanisms can be divided into three types: mechanical, hydraulic, and booster-assisted. The details are as follows: 1. Mechanical operating mechanism: Uses the driver's physical strength as the sole operating energy source. It comes in two types: linkage and cable transmission. The former is characterized by multiple pivot points, significant friction loss, susceptibility to deformation of the frame or body during operation, and the inability to use a suspended pedal. This mechanism is commonly used in trucks. 2. Hydraulic operating mechanism: Amplifies the force applied by the driver on the pedal through a hydraulic master cylinder to operate the clutch transmission device. Its features include low friction resistance, light weight, convenient arrangement, smooth engagement, and immunity to body shape influences. It is commonly found in mid-to-high-end sedans and light buses. 3. Pneumatic-assisted hydraulic operating mechanism: In medium and heavy-duty vehicles, to reduce pedal force without increasing the pedal stroke due to an excessively large transmission ratio of the transmission device, a pneumatic-assisted hydraulic operating mechanism is generally used. This utilizes an engine-driven air compressor as the primary operating energy source, with the driver's physical effort serving as auxiliary and backup operating energy.
