What is Electric Power Steering Rack and How it Works?

The steering rack is the most essential part of any vehicle that operates using a rack and pinion steering system. It is the component that takes the circular motion of the steering wheel and converts its movement into a linear motion. In the case of a power steering assembly, the rack is controlled using a hydraulic mechanism that is driven by the engine which makes it a lot easier to turn the steering wheel and the vehicle itself. Of course, being a hydraulic system also means that all the components needed to create a highly pressurized and sealed chamber need to be present.

4. Steering Performance Testing

Steering performance testing is a great way of checking if the steering assembly of a particular car is working as expected. There are plenty of tests that are conducted to measure the performance of each component and they can include the following:

1. Steering Input Assembly
   1. Steering input operation frequency
   2. Maximum steering input angle
   3. Maximum steering input torque
   4. Maximum steering input velocity
2. Rod Input Assembly
   1. Tie rod input lateral frequency
   2. Tie rod input lateral force
   3. Tie rod input lateral velocity
   4. Tie rod input lateral stroke
   5. Tie rod Input Vertical Frequency
   6. Tie rod Input Vertical Force
   7. Tie rod Input Vertical Velocity
   8. Tie rod Input Vertical Stroke
