Automobile steering system is used to maintain or change the direction of the car, in the car steering driving
, to ensure that the steering wheel has a coordinated angular relationship between. It consists of steering control mechanism, steering gear and steering
transmission mechanism.
Steering system as an important part of the car, its performance will have a direct impact on the car
steering characteristics, stability, and driving safety. At present, there are seven major categories of automobile steering technology:
manual steering technology (MS), hydraulic power steering technology (HPS), electronically controlled hydraulic power steering technology
(ECHPS), electric power steering technology (EPS), four-wheel steering technology (4WS), active front wheel steering
technology (AFS) and steering-by-wire technology (SBW). The steering system market is dominated by HPS, ECHPS, and EPS applications
. Electric power steering has the advantages of fuel saving, environmentally friendly, variable force steering, easy to realize product modularity, etc. It is a new technology that closely follows the theme of today's automobile development, and it is the research hot spot of
steering technology in China at present.
