How do servo presses contribute to the ultimate experience of hydraulic suspension?
The evolution of automotive suspension ultimately aims to make driving more exhilarating and riding more comfortable. While traditional suspensions provide damping, they often force a compromise between comfort and handling .

To overcome this limitation, engineers have continuously explored new paths. The emergence of hydraulic suspension acts like a "performance upgrade," enabling vehicles to perform adeptly across various scenarios. It delivers smoothness and stability on bumpy city roads, rugged mountain paths, and even during high-speed cornering .

01 The Secret to an Instant "Smooth Road"

The greatest advantage of hydraulic suspension lies in its millisecond-level response speed and extensive adjustment range. When encountering uneven road surfaces, it can instantly absorb impacts, providing an experience as smooth as driving on a level surface .

During aggressive driving, it can rapidly provide robust support, enabling excellent dynamic performance for the vehicle, even achieving extreme maneuvers like an "in-place jump." All this relies on a precise and powerful core power system .

02 The High-Pressure Pump: The True "Mastermind"

The "Heart" of Hydraulic Suspension

The "heart" of the hydraulic suspension is the high-pressure oil pump. Operating under extreme pressures exceeding 200 Bar, the pump must continuously deliver stable power to ensure the system's rapid response and precise control .

The Reliability of Oil Seals and Sealing Rings

The requirements for sealing are extremely stringent here. Even minute leakage can lead to performance degradation or complete functional failure. Therefore, the reliability of oil seals and sealing rings is critical for the stable operation of the entire system. To eliminate this risk entirely, advanced assembly processes become an indispensable safeguard .

The "Unsung Hero" Behind the Ultimate Experience

High-precision servo presses play an irreplaceable role. They offer micron-level press-fitting accuracy, enabling stringent control over the position and force applied to seals. More importantly, they feature unique force closed-loop control functionality .

By applying and maintaining constant pressure after press-fitting, the servo press effectively counteracts the rebound of seal components caused by plastic deformation, fundamentally avoiding the risk of seal failure. This process provides a solid foundation for the high-pressure oil pump to maintain a leak-free performance even under extreme operating conditions .

It is this meticulous manufacturing craftsmanship that allows hydraulic suspension to truly excel. The high-pressure oil pump remains rock-solid due to superior sealing, and the servo press is crucial for its precise press-fitting. The two work in synergy, enabling the vehicle to offer thrilling performance on curves and a smooth, level ride on bumpy roads. Ultimately, this provides drivers with a driving experience that combines excitement and comfort
