Body Components

Coupler

The coupler buffer is a key component of railway vehicles or heavy transport equipment. Its function is to connect
vehicles, transmit traction/braking force, and buffer the impact force during operation.Transmit the traction force of the tractor to the subsequent carriages, and at the same time transmit the braking force in the opposite direction to achieve coordinated acceleration or deceleration.Springs, hydraulics or rubber elements are used to absorb the impact energy during vehicle starting, braking and collision, thus reducing structural damage. For molten iron tanks, buffering can reduce the risk of molten iron sloshing and prevent high-temperature liquid from overflowing.

Train Bogie

The bogie is the wheel axle assembly at the bottom of the vehicle. Bogie supports the weight of the vehicle body through multiple wheel sets and suspension systems to ensure the stability of the vehicle on straight and curved roads. At the same time, it allows the wheel sets to rotate independently, so that the vehicle can pass through curves flexibly and reduce the risk of derailment. The suspension system such as springs and dampers absorbs the vibration caused by uneven tracks to improve passenger comfort.
