Commercial vehicles operate in harsh environments: heavy payloads, frequent stops, and uneven roads. A recirculating ball type steering system addresses these pain points:
High Torque, Low Effort: The recirculating ball-and-nut mechanism generates up to 2000Nm of torque, making heavy trucks feel responsive.
Smart Assistance: An electric motor adjusts power based on speed and load, reducing driver fatigue during long hauls or tight maneuvers.
Seamless Integration: Designed to fit existing vehicle architectures, it supports features like ADAS and OTA updates without major redesigns.
For vehicle manufacturers, this means a solution that balances performance, cost, and time-to-market-critical for staying competitive in fast-evolving markets.
Core Components: Built for Reliability
Every part of our recirculating ball type steering system is engineered for commercial toughness:
Angle Sensor:
Tracks steering wheel position with ±0.5° accuracy, ensuring the motor delivers precise assistance.
ECU (Electronic Control Unit):
Runs adaptive algorithms to adjust power based on speed, temperature, and load. It supports CAN/CANFD communication, linking seamlessly to your vehicle's network.
Electric Motor:
TRION X-EPS 915 uses a brush motor (cost-effective for light loads), while the X-EPS 2000 uses a brushless motor (more efficient for heavy-duty cycles).
Ball Screw Assembly:
TRION recirculating ball screw minimizes friction, ensuring smooth operation over hundreds of thousands of cycles.
Product Introduction: How It Works
At its core, TRION recirculating ball type steering system uses a ball-and-nut assembly to convert rotational motion into linear force, amplified by an electric motor. Here's what sets our two models apart:
X-EPS 915 (Brush Motor)
Torque: 915Nm (ideal for light-duty trucks/vans).
Motor: Brush electric motor (400W, 60A) for cost-effective reliability.
Use Case: Perfect for 3.5T–8T vehicles like delivery vans or light cargo trucks.
X-EPS 2000 (Brushless Motor)
Torque: 1600–2000Nm (built for heavy loads).
Motor: Brushless electric motor (650W–880W, 80A–110A) for efficiency and durability.
Use Case: Suited for 8T–12T trucks, including specialty vehicles like refrigerated carriers.

FAQ: Answers for Vehicle Manufacturers
Q1: How long does it take to integrate the system into our platform?
Most integrations take 8–12 weeks for standard setups. Custom modifications add 4–6 weeks, but our modular design minimizes chassis changes.
Q2: Can we customize the system for our specific vehicle?
Yes. We adjust torque ranges, motor specs, and even communication protocols. For example, we've modified the X-EPS 915's calibration for a client's low-speed delivery trucks in 10 weeks.
Q3: What support do you offer during production?
Our team provides on-site assistance for assembly line integration, calibration, and first-run optimization. We also share CAD models and simulation data to streamline your design process.
Q4: Do you have case studies of this system in similar commercial vehicle projects?
We've successfully deployed TRION recirculating ball type steering system in light trucks, delivery vans, and specialty vehicles. For example, one project reduced driver steering effort by 30% in fully loaded conditions while improving highway stability. While we can't share specific client names, we can provide anonymized performance data, test reports, or even arrange a benchmark comparison with your current steering solution.
