Pakistan use oil damper for railway bogie

Pakistan use oil damper for railway bogie:

Our company is main supply railway rolling stock and equipment. The TYG oil damper can be widely used in rail transit vehicles,such as locomotives,passenger cars,turcks,light rails, and subway,etc. it can operate normally in enviroment with wind,sand,rain,snow,ice,weak acid fog,intensive ultraviolet,sandstorm and drect sunlight(operating temperature:-45℃~80℃)

Technical characteristics:

Oil damper is a colsed hydraulic system,When there is relative movement caused by vibration between the vehicle bogie and axle box(or between vehicle body and bogie,or between two vehicle bodies),the damper piston repeatedly pulls and presses in the inner cylinder,producing high pressure oil inside the inner cylinder for pressing.

The damper adopts airbag two drum structure and mainly includes the following components:rubber joint assemble,cover assmble,piston rod,outer cylinder nurt,oil seal ring,corrugated oil seal,guide cover,inner cylinder,bottom valve assmbly,outer cylinder,o-ring,piston assmbly,piston ring, and airbag assmble.

the dampers has the charactersics of overload unloading, automatic protection.

the dampers has reliable performance, convenient maintenance, competitive price performance.

series of damper:

Type:

1. primary vertical damper(axle box damper)

it is used to control vertical movement between axle box and bogie. I.E nodding vibration.

2. Secondary vertical damper

it is used to control vertical movement between carbody and bogie. I.E nodding vibration and bouncing vibration

3. Secondary lateral damper

it is used to control lateral movement between carbody and bogie. I.E lateral  vibration and yawing vibration.

4. Yaw damper

it is used to control hunting movement between carbody and bogie. I.E hunting motion

5. Coupling damper

it is used to control lateral movement between motor hanging beam and bogie. I.E lateral vibration.
