Rail Vehicle

Rail vehicles are driven on railroad tracks, with multiple carriages forming a train, covering public transportation systems such as high-speed rail, railroad, metro, and light rail transit. The vehicle is composed of five major elements, namely: body, steering rack, braking device, connecting buffer device, and internal equipment of the vehicle.
Due to rubber products having multi-functional purposes such as drainage, vibration control, and sealing, rail vehicles use a large number of rubber parts to achieve a balance between noise and vibration control.
For example:

• The fabric pattern rubber hose is used for the transmission of braking power
• The rubber bearing axle reduces the torque of the steering rack
• The rubber strip is used for the door or window frame to isolate the noise inside and outside the carriage
• The O-ring is used for the oil leakage prevention
• The rubber foam strip is used for the vibration-damping seal of the air conditioning system
• The wire braided rubber pipe is used for the water transmission and the sewage discharge, etc.

Most of the railway vehicles will return to the factory for maintenance and repair after a certain mileage for safety and prolonging the service life of the transportation system, and rubber parts are also listed as the main inspection items during the overhaul to meet the requirements of the public transportation system safety standards.
