Two Wheeler Clutches

Plate Type Two Wheeler Clutches

Plate Type Clutches consists of set of friction plates & steel plates that are pressed under the spring load & transmits the power from engine to gearbox and subsequently to drive wheels.
This clutch is an arrangement of plates stacked in alternating fashion, one geared on the inside to the engine, and next geared on the outside to the transmission input shaft. Whether wet or dry, the plates are squeezed together by a spring, causing friction buildup between the plates until they rotate as a single unit, driving the transmission directly. Know more..

Centrifugal Two Wheeler Clutches

Centrifugal Clutch is based on the principle of centrifugal force. This clutch uses a combination of friction Discs (like brake shoe) and floater (outer) to transfer power from the engine to the drive wheels. In all centrifugal clutches, centrifugal force works against spring tension to determine whether the clutch is engaged or not. At low rpm, the spring tension is greater than the centrifugal force and the clutch spins freely. As the engine speed increases, the centrifugal force begins to overcome the spring tension and at one point of time friction discs get engaged with floater and transmit the power.

Four Wheeler Clutches

Manual Transmission Four Wheeleer Clutches

Manual Transmission
are characterized by gear ratios which are selectable by engaging pairs of gears inside the transmission. Manual Transmission is a type of transmission used in automotive applications. Manual Transmissions often feature a driver-operated clutch and a movable gear selector, although some do not. Most automobile manual transmissions allow the driver to select any gear at any time, but some, such as those commonly mounted on motorcycles and some types of race cars, only allow the driver to select the next- highest or lower gear ratio.

Soul of Clutch

Clutch Friction Disc-Two Wheelers

The clutch friction Disc, also called as friction lining, consists of a splined round metal plate covered with friction material (lining). The splines in the center of the clutch Disc mesh with the splines on the input shaft of the manual transmission. This makes the input shaft and Disc turn together. However, the Disc is free to slide back and forth on the shaft.

Cork Base & Paper Base Clutch Friction Disc

The cork base clutch friction Disc is made of heat–resistant non-asbestos cork, cotton fibers and copper wires moulded together. Grooves are cut into the friction material to aid cooling and release of the clutch Disc. In some cases, rivets are used to bond the friction material to both sides of the metal body of the Disc.

The paper base clutch friction Disc is made of heat–resistant cellulose, cotton fibers and copper wires moulded together. Cellulose is used to prolong life of the clutch and provide more torsional strength. Paper CFD has more life than cork base friction material as it possess :-

More heat resistant property
Low wear and tear characteristics
High endurance
Low warranties
