A drum is an outer part of the clutch that rotates in conjunction with the crankshaft of the engine. The drum encloses every component of the clutch, including the guides, sliding shoes, springs, friction lining, and others. The drum is connected to the driven shaft of the belt, chain, or transmission system.
#2 Clutch Basket
As the name suggests, the clutch basket is a stationary part of the clutch system that holds clutch plates until they are needed.
#3 Clutch Plates
From the engine to the transmission, the clutch plate acts as a friction disc to transmit the power from the engine to the transmission.
A clutch plate is held in place by a clutch spring that applies pressure and helps keep the clutch plates engaged with each other. Spring is typically used at slower speeds. Each shoe has a spring attached to it.
When the clutch is engaged, the shoe is a component that is attached to the weights, and it is in contact with the clutch basket when the clutch is engaged. Shoes are a potential source of friction.
The shoe is attached between the guides and functions primarily as a sliding object. The shoes used to slide in guideways. It has a friction lining at the very end.
#6 Friction Lining
A component of the sliding shoes is the friction lining. The friction lining operates on the same logic as a basic clutch’s friction plate. This friction lining can be attached to the outermost portion of shoes.
An inner friction lining transfers torque, making the drum’s inner surface more gripped. The sliding shoes and the drum are kept from coming into direct contact. By doing this, the sliding shoes experience less wear and tear.
The spider is mounted to either the driver (engine) shaft or the motor shaft. Since there is an equal distance between each spider, there is also an equal distance between each guide.
As an illustration, if three guides are present, the next guide is 90 degrees away from the first guide. The shoes are kept in between these guides to absorb the friction, and each guide has a spring to disengage the clutch.
The clutch is engaged by weights, which are parts that are fastened to the drum. The weights move outward as the engine speed rises due to centrifugal force and make contact with the clutch basket, engaging the clutch.
The clutch is connected to the engine crankshaft by a key, enabling it to rotate with the engine, and is another crucial component.
