Electrohydraulic Power Steering Lecture 5 Day 2-Class 2
Introduction • Electrohydraulic steering can refer to • A hydraulic power steering system driven with an electric motor • A power steering system that uses wires to sense the steering wheel input and actuate the steering valve
Electric Motor • An electric motor can be used to power the steering pump instead of the engine • Lowers fuel consumption • Allows for more flexibility of design
Sizing electric motors • Electric motors are sized by horsepower • We need to determine the horsepower required to drive our pump • Horsepower should be around 0.25 HP • A 1 horsepower motor would be much too large for our space considerations
Considerations for E-H System Design • Simulation of end stops • Operational environment • Safety • Steering functions • Force feedback
