Commercial vehicles face a relentless cycle of heavy loads, stop-and-go driving, and unpredictable road conditions. A power recirculating ball steering system addresses these pain points head-on:
Torque for Tough Jobs: Unlike passenger car systems, its recirculating ball mechanism generates high torque with minimal effort, making fully loaded trucks feel agile.
Smart Assistance: An integrated electric motor adjusts power based on speed, payload, and even driving mode, reducing driver fatigue.
Future-Ready Flexibility: Designed to integrate with modern vehicle architectures, it supports features like ADAS and over-the-air (OTA) updates-no hardware overhaul needed.
Core Components: Built for Reliability
At its heart, TRION power recirculating ball steering system uses a recirculating ball-and-nut assembly to convert rotational motion into linear force, then amplifies it with an electric motor. Every part of our power recirculating ball steering system is engineered for commercial toughness:
Angle Sensor:
Tracks steering wheel position within ±0.5° accuracy, ensuring the motor delivers the right assistance at the right moment.
ECU (Electronic Control Unit):
Runs adaptive algorithms to adjust power based on speed, temperature, and load. It also supports CAN/CAN FD communication, seamlessly linking to your vehicle's network.
Brushless Motor:
More efficient, quieter, and longer-lasting than brushed motors-perfect for vehicles logging high daily mileage.
Ball Screw Assembly:
TRION recirculating ball screw converts motor torque into smooth linear motion, minimizing friction and wear over thousands of cycles.
Product Classification: Tailored to Your Vehicle
Our power recirculating ball steering systems are organized around real-world use cases:
x-EPS 915 (electric recirculating ball steering)
Efficiency Series (900–1500Nm): Optimized for light trucks and vans (3.5T–8T) where fuel efficiency and cost-effectiveness matter. Balances power and energy savings.
X-EPS 2000 (electric recirculating ball steering)
Heavy-Duty Series (1500–2000Nm): Ideal for 8T–12T trucks or vehicles with constant heavy payloads. Extra torque ensures easy maneuvering even under maximum load.
