They are not the same concept. Rack and pinion is a specific mechanical structure responsible for converting the rotation of the steering wheel into the steering of the wheels; while power steering is an auxiliary system designed to reduce the amount of effort required by the driver during steering.

Although the basic design of the two is similar, the steering ratio of the power system is usually designed to be lower due to the addition of the power system, while the manual system tends to have a higher steering ratio.

The following are some common names for hydraulic steering gears: 1. Power Steering System 2. Assisted Steering 3. Hydraulic Power Steering System 4. Rack and Pinion Steering 5. Hydraulic Assist System

A damaged steering rack may cause inaccurate steering of the vehicle. This phenomenon is usually manifested as the actual steering angle of the vehicle does not match the expected one after the driver turns the steering wheel, or the steering response is slow.

Selected innovative model: Citroën 2CV The Citroën 2CV was the first car in the world to use a rack and pinion steering system extensively. The car debuted at the Paris Motor Show in 1948 and became a major highlight of the automobile market at the time.

For light vehicles and small cars, rack and pinion steering systems usually provide sufficient handling performance and driving comfort. For heavy vehicles or large SUVs, power steering systems are particularly important. The weight and size of heavy vehicles make steering operations more difficult.

Steering rack is core of the steering system.Just like a heart for human. It promise you a better driving experience.
