How A Slipper Clutch Works? | How Slipper Clutch Can Make You Faster And Safer On A Bike | Hindi

When you are riding at high speeds and suddenly you encounter a sharp corner – the obvious reaction would be to slow down by applying the brakes and shifting in lower gear. But what if you have lesser time and you want to shift 2-3 gears at a time? And when you do this, you do it at the cost of damaging the gear box and putting your safety at risk which arises due to engine braking force. As a mechanism to reduce these issues, Slipper Clutch (also known as back torque limiter clutch) was introduced. Slipper Clutch helps by allowing the clutch to partially slip until the engine speed matches your own speed.

In normal clutches, the engine braking force is transmitted to rear wheel via chain drive (or shaft drive) which causes rear wheel to shake, jump or lose traction. This is the main concept behind slipper clutch – to control rear wheel under hard braking and downshifting that causes the rear wheel to lose traction. It is particularly helpful especially on higher displacement bikes where the engine braking force is massive and may cause the motorcycle to go out of control, resulting in a high-speed collision/accident!

What Is Engine Braking?

When you open the throttle on a motorcycle, the engine produces an accelerating effect by sending positive torque to the rear wheel through the clutch and transmission. On the other hand, when you are off the petrol, the engine sends negative torque to the rear wheel, creating a braking effect. This braking effect is called Engine Braking. That's because in this case, you are not applying brakes, instead, it is the engine that produces a retarding effect on the rear wheel. Engine Braking is useful as it reduces the speed of the vehicle without actually using brakes but it can be harmful if you are an amateur rider or accidentally downshift too aggressively.

When you engage the conventional clutch, its primary function is to transmit the torque via the transmission. Slipper clutch works exactly the same way. The only difference is, it disengages when met with a certain level of back torque thereby, transmitting this back torque away from the engine. Then it engages again and the cycle continues until it achieves neutrality between the forces of the rear wheel and the engine. It absorbs all the back torque when it disengages. This peculiar feature of this type of clutch avoids losing traction of the rear wheels.
