Because EPS systems can adjust power-assist characteristics according to vehicle speed-providing greater assistance at low speeds to reduce steering effort and reducing assistance at high speeds to enhance road feel-they are widely adopted in mid-to-high-end vehicle models. Furthermore, electric power-assist pumps exhibit a lower failure rate than hydraulic systems and do not require periodic hydraulic fluid changes, resulting in lower maintenance costs.
Steering power-assist pumps find application across a wide range of sectors, including passenger vehicles, commercial vehicles, and construction machinery. In passenger vehicles, power-assist pumps must meet requirements for lightweight design, low noise levels, and rapid response. Commercial vehicles, due to their heavy load-carrying capacities, impose more stringent demands on the durability and torque output of the power-assist pumps. Construction machinery-such as forklifts and excavators-must operate under complex working conditions; consequently, their power-assist pumps require robust dust-proofing, waterproofing, and shock-resistance capabilities. For instance, the steering power-assist pump utilized in a specific model of stacker truck features an optimized oil circuit design and sealing structure, enabling it to operate stably within a temperature range of -30°C to 80°C; simultaneously, by minimizing mechanical friction, it reduces energy consumption and extends the product's service life.
