Train Dampers

  • The train dampers from Yonggui Electric quickly attenuates the vibration transmitted from the road to the body of the vehicle, and improves improve the ride comfort.

  • Make the seat is not easy to fatigue goods are not easy to damage.

  • Reduce the impact on related parts, reduce wear, improve the use of economy.

  • Improve wheel grounding to inhibit high-speed wheel bounce and improve driving safety.

  • The vehicle in the rapid acceleration, rapid deceleration, sharp corners, improve the stability of operation.

Application of Yonggui Electric's Train Dampers

  • Natural environment (wind, sand, rain, snow, light, temperature, etc.). 

  • Working conditions (uneven, ramps, bends, joints, switches, acid and alkalicleaning agent, flying stone impact. 

  • Vibration from external excitation or itself . Ø Impact caused by acceleration and deceleration. 

  • The running speed. 

  • The stationarity index. 

  • Load or axle load. 

  • Maintenance-free cycle or mileage.

Working Principle of Yonggui Electric's Train Dampers

Most of the suspension systems of modern vehicles use oil dampers. The working principle of this part in rail connectivity solution, including those designed by Yonggui Electric, is when there is relative motion between the bogie and the axle box (or the body of vehicle and the bogie) due to vibration. The piston in the damper moves up and down, The oil in the working cylinder flows from one chamber to the other through the orifice, At this time, the friction between the valve systemand the oil and the internal friction between the oil molecules produce damping force on the vibration, The vibration of the vehicle is suppressed, Vibration energy is converted into heat energy, Radiate into the atmospher.
