Electric Power Steering System for Bus
Our rack-assist type electric power steering system (R-EPS) for large commercial vehicles like buses is designed with integration, lightweight construction, and energy efficiency in mind, making installation much more efficient. It’s about 15 kg lighter and more compact than traditional EHPS systems. Plus, it only activates during steering, saving 4 kWh of energy per day. Over five years, this adds up to about $3000 in savings on electricity and battery costs.

Working Principle of the Bus Electric Power Steering System
After the motor outputs torque, it is reduced and amplified through the worm gear system. The worm gear drives the ball screw, which moves the piston rod in a linear motion. The piston rod, connected to the outer tie rod via a ball joint, pushes or pulls the steering arm, turning the wheels.
Unlike traditional hydraulic power steering systems, this EPS for hybrid or battery electric buses provides a smoother ride. This innovative system controls the operation and torque output of the electric power steering motor according to the driving speed of the vehicle and the steering torque and steering angle of the driver’s steering wheel after processing and calculation by the steering electronic control unit (ECU). It’s a device that optimizes the effect of power steering.
