The resiliency wheel are a type of split wheels that are currently used in tram vehicles traveling on urban surfaces.
Resilient wheels, achieved by installing viscoelastic rubber inserts between the wheel rim and spokes, are softer compared to traditional rail wheels, thus reducing the forces between the wheel and rail. They are suitable for light rail vehicles with axle loads of up to 10 tons.
Compared to rigid wheels, resilient wheels can decrease external noise by 3.5 to 4 dB(A), internal noise by 3 dB(A), and noise during curve negotiation by approximately 10 to 20 dB(A). Widely adopted in Europe, Japan, and the United States, despite high manufacturing and maintenance costs, they play a crucial role in improving urban transportation noise pollution.
The structure of tram resilient wheels typically includes four main components: the wheel hub, rim, pressure ring, and vibration damping rubber blocks. The rubber blocks are compressed between the rim and hub to isolate and attenuate wheel vibrations. Constituent materials of resilient wheels consist mainly of metal components, with rubber blocks providing the primary damping mechanism.
Resilient wheels represent a significant technological innovation in urban rail transportation. By effectively reducing noise pollution, damping vibrations, and optimizing energy efficiency, they create a quieter, smoother, and more environmentally friendly operating environment for trains.
The durable design of resilient wheels extends their service life and reduces maintenance frequency and costs, thereby minimizing their impact on urban environments.
