The clutch is located in the flywheel housing between the engine and the gearbox, and the clutch assembly is fixed on the rear plane of the flywheel by screws, and the output shaft of the clutch is the input shaft of the gearbox. In the course of the car, the driver can step on or release the clutch pedal as needed, so that the engine and the gearbox are temporarily separated and gradually joined to cut or transfer the engine to the transmission input power. The clutch is similar to a switch, joining or breaking off the power transfer, so that any form of car has a clutch device, just the form is different.Gasoline Scooters
     To ensure a smooth start of the car, this is the primary function of the clutch. Before the car starts, it is natural to start the engine first. When the car started, the car was gradually accelerated from a completely stationary state. If the driveline (it links the whole car) with the engine just.Gasoline Scooters
     Sexual contact, the transmission is put on the gear, the car will suddenly go forward, but can not start. This is because the car from the static to the front of the rush, with a great deal of inertia, the engine caused by the Earth resistance moment. Under the action of inertia resistance moment, the engine in the instantaneous time speed drops to the lowest stable speed (general 300-500rpm) below, the engine is flameout but cannot work, certainly the automobile also cannot start.Gasoline Scooters
     In the course of automobile driving, in order to adapt to the changing driving conditions, the transmission system often needs to change the different gear position work. The realization gear transmission's shift, generally is moves the gear or other hangs the gear mechanism, causes the original use gear pair to launch the transmission, then causes another gear pair to enter the work. In the shift before the clutch pedal, interrupt power transmission, easy to make the original gear of the meshing pair off, at the same time make the new gear meshing part of the speed of the meshing is gradually synchronized, so into the meshing impact can be greatly reduced to achieve smooth shift.Gasoline Scooters
     Prevents the transmission system overload when the automobile carries on the emergency braking, if does not have the clutch, then the engine will cause and the transmission system rigid connection to reduce the speed sharply, therefore, all the moving parts will produce a great inertia torque (the numerical value may greatly exceed the maximum torque emitted by the engine when it works), and the drive system causes more load than its carrying capacity, which causes the mechanical damage. With a clutch, it is possible to eliminate this danger by relying on the relative movement that may arise between the active part of the clutch and the moving part.      Therefore, we need the clutch to limit the maximum torque of the transmission system and ensure safety.Gasoline Scooters
Although the boys will generally be interested in cars, but all are for the appearance of the car, performance, brand, history, and the specific composition of the car, the principle can basically be said to be ignorant. In the junior high school physics textbook, once briefly introduced 2-stroke engine and 4-stroke engine, but for us, about the engine knows is the displacement bigger horsepower, and the engine is burning oil. Because of this curious psychology, in the choice of optional comprehensive experiment, the choice of gasoline scooter disassembly, although only 2 of wheels, but also a set of complete engine system, for us, is also a huge challenge.Gasoline Scooters
