Here you can get types of multi-plate clutch. Multi plate clutch used in different types of vehicles.
Multi-Plate Clutch consists of a number of clutch plates instead of only one clutch plate like in the Single plate clutch. Friction surface also increased because of a number of clutch plates. Because of a number of friction surfaces, The capacity of the clutch to transmit torque is also increased.
Multi-Plate Clutches are four types. These clutches are used in automatic transmission.
1.Spring Type Multi-Plate Clutch
In the clutch, a cowl attaches with a flywheel of engine use internal which the multiple clutch plates, pressure plate, thrust bearing, etc. packed. The clutch plates location over every different and mount over a splined shaft.
2. Diaphragm Type Multi-Plate Clutch
It is the changed model of the spring type multi-plate clutch. In which the thrust springs locations circularly from the spring kind clutch replace with a special crown-form finger kind spring referred to as diaphragm spring.
3. Hydraulic Operated or Automatic Clutch
It is the modern type of clutch makes use of in motors geared up with automatic transmission, in this type of clutch a hydraulic tool having highly compress fluid operates with the accelerator pedal coupled with the multi-plate clutch.
4. Wet Multi-Plate Clutch And Dry Multi-Plate Clutch
Multi-Plate wet Clutch When the clutch is operated in an oil bath, it is called a wet clutch. In this clutch plate, Thin plates of steel fitted to engine shaft (means drive shaft) and phosphor Bronze plates are fitted to the clutch shaft (means driven shaft). Multi-plate clutch has grooved surfaces for allowing the oil to flow through them. These grooves decrease heat generated when engage and disengage operations.
Multi-Plate dry Clutch When the clutch is operated dry it is called dry clutch. This clutch has plates with friction material the same as in single plate clutch.
The plates are alternately fitted to the engine crankshaft and gearbox shaft. They are firmly pressed by strong coil springs and assembled in a drum type casing.
Each of the alternate clutch plate slides on the grooves on the flywheel and the other slides on splines on the pressure plate. Thus, each alternate clutch plate has inner and outer splines.
Where Multi-Plate Clutches are used?
The multi-plate clutches are used in racing cars, heavy commercial vehicles, and motorcycles.What are the disadvantages of Multi plate clutch?
Multi-plate clutches are too expensive and heavy.
