Flywheel CouplingFlywheel couplings are components of engines that store energy and angular momentum, and ensure steady shaft rotation when there is uneven torque. They are mainly used within the construction and automotive industries. These couplings are used in all sorts of vehicles, in their transmission and engine. Off-highway construction equipment such as skid steel loaders, aerial lifts, excavators, harvesters, bucket loaders, wheeled loaders and baggage handlers all use flywheel couplings. All cars use flywheel couplings in their manual transmission. They are very heavy, take up little space and are able to work in temperatures up to 250 degrees F. This method of storing energy is used when a high demand for power is used because using flywheel couplings won’t negatively effect the equipment. These 1 or 2 piece engine components are composed of a flange, hub and metal (usually steel or aluminum) housing. They are attached to a rotating shaft and smooth the delivery of the torque from the motor or engine. These couplings need very little change in speed to operate correctly and are designed to carry enough energy to power a car between the firing of each cylinder. In manual transmission, a friction plate is placed between a flywheel coupling and pressure plate. This allows the engine shaft to turn the transmission. The weight and size of flywheels directly correlate with the size and weight of the vehicle. The larger, heavier truck flywheel couplings are heavier so they may store more energy and offer faster acceleration.
