Youdaoplaceholder0 Automobile steering systems mainly include two types: mechanical hydraulic power assist and electric power assist, each with its own advantages and disadvantages.
Mechanical Hydraulic Power Steering System (HPS)
Mechanical hydraulic power steering system (HPS) is a traditional steering system, mainly composed of hydraulic pumps, oil pipes, pressure and flow control valve bodies and other components. Its working principle is that the engine drives the hydraulic pump, and the power of the hydraulic oil is used to help the driver turn the steering wheel.
Youdaoplaceholder0 Advantages :
Youdaoplaceholder0 Clear road feel feedback : As it is mechanically connected, the steering wheel can precisely convey road information and is suitable for drivers who seek a sense of control and enjoy the pleasure of driving.
Youdaoplaceholder0 Mature technology : Easy to maintain and highly reliable.
Youdaoplaceholder0 Disadvantages :
Youdaoplaceholder0 Higher energy consumption : The engine needs to constantly consume power to keep the hydraulic system working, resulting in lower fuel efficiency.
Youdaoplaceholder0 High maintenance cost : The hydraulic oil and seals need to be replaced regularly, and the hydraulic lines and oil pump are prone to aging and leaking oil.
Youdaoplaceholder0 Complex structure : takes up more space and is more complicated to maintain.
Electric Power Steering System (EPS
Electric power steering system (EPS) is a new type of steering system, mainly composed of steering sensors, electronic control units, electric motors and other components. Its working principle is to provide auxiliary force through an electric motor and automatically adjust the magnitude of the assistance according to the vehicle speed and steering Angle.
Youdaoplaceholder0 Advantages :
Youdaoplaceholder0 Low energy consumption : Consumes electricity only when turning, overall low energy consumption, more environmentally friendly.
Youdaoplaceholder0 Simple structure : No complex hydraulic lines or oil pump, low maintenance cost, and no problem of hydraulic oil leakage.
Youdaoplaceholder0 Strong adaptability : Can automatically adjust the assist size according to the vehicle speed, light and agile at low speed, stable and reliable at high speed.
Youdaoplaceholder0 Disadvantages :
Youdaoplaceholder0 Road sensing feedback is not as clear as hydraulic assist : Many electronic components may lose some road sensing.
Youdaoplaceholder0 LESS reliable : More electronic components, less stable system than mechanical components, prone to failure.
Youdaoplaceholder0 HIGH repair cost : Although the cost of daily use is low, the repair cost may be high once it breaks down.
