Metallic bellows seal geometry: BYDRecent Research Landscape

Pressure fluctuations in hydraulic systems cause mechanical fatigue and fluid loss, which are mitigated through hermetically sealed flexible bellows integration. This engineering approach ensures zero-leakage energy storage while accommodating high-frequency volumetric changes.

What technical problems is BYD addressing in Metallic bellows seal geometry?

Excessive mechanical vibration transmission

(40)evidences

Mechanical shock and vibration transfer from the road surface to the vehicle chassis. Reducing these forces prevents structural fatigue and improves passenger ride quality.

Pressure fluctuation induced fatigue

(9)evidences

Cyclic pressure variations in hydraulic systems cause mechanical stress and material fatigue in containment vessels. Addressing this prevents structural failure and extends the operational lifespan of vehicle fluid systems.
