CH5a: Steering Technology (W9)

What is the function of the steering system in a vehicle?

• Adjusting the seat position

• Swinging the wheels to the left or right

• Changing the radio station

• Adjusting the side mirrors

What is the purpose of rack and pinion steering in modern cars?

• To convert circular motion into linear motion for steering

• To convert linear motion into linear circular for steering

• To control the fuel injection system

• To adjust the suspension system

What is the main advantage of RACK & PINION steering linkage?

• It improves vehicle stability and safety

• It provides better response at different speeds

• It allows the wheels to lock from far left to far right

• It reduces fuel consumption

What is the function of power steering in a vehicle?

• To adjust the vehicle's suspension height

• To increase the weight of the steering wheel

• To reduce steering effort needed to turn the steering wheel

• To control the vehicle's airbag system

What is the difference between Hydraulic Power Steering (HPS) and Electric Power Steering (EPS)?

• HPS is less prone to problems and faults compared to EPS

• HPS extracts power from the battery, while EPS uses hydraulic fluids

• EPS System is complicated compared with HPS

• HPS usually weighs more than EPS

What is the working principle of Electro-Hydraulic Power Steering (EHPS)?

• It uses an heat to reduce steering effort

• It provides power assist via hydraulic pressure

• It operates all the time

• Hydraulic pressure is provided by a pump driven by an engine

What is the purpose of Speed Sensitive Steering in a vehicle?

• To improve vehicle stability while maneuvering at low speed

• To give a more direct feel at different speeds

• To reduce fuel consumption at low speed

• To heavily assist steering at high speed

What is the main advantage of Four Wheel Steering in a vehicle?

• It increases vehicle stability while maneuvering at high speed

• It decreases turning radius at high speed

• It allows all four wheels to turn at the same time when the driver steers

• It improves fuel economy at low speed

What is the aim of Steer by Wire technology in automobiles?

• To improve fuel economy by using hydraulic pressure

• To completely do away with as many mechanical components as possible

• To increase the weight of the steering wheel

• To provide power assist via hydraulic pressure

What is the characteristic of the ZF Servotronic® 2 system?

• It offers true speed-dependent power steering

• It uses an electronic control unit (ECU) to reduce steering effort

• It decreases the turning radius at low speed

• It increases the mechanical or electrical assistance as the vehicle speed increases
