Power Steering-https://youtu.be/Fkgp64e-nNQ?si=A0ejZmL9Qyc31Ux_

What is the purpose of the rotary valve in a hydraulic power steering system?

• To regulate the pressure distribution between the left and right halves of the hydraulic cylinder

• To measure the torque being exerted on the steering wheel

• To transmit motion through a belt to a recirculating ball gear

• To add or subtract angles to the direction of rotation

Where is the torque sensor located in an electric power steering system?

• On the pinion driving the rack

• On the steering column

• On the rack itself

• On the electric motor

Which technology was introduced by BMW 5-series in 2003?

• Hydraulic power steering

• Electric power steering

• Active steering

• Electronic stability program

How does the electric motor behave in low speed mode in active steering?

• It supplements the rotation of the driver

• It counteracts the driver's instructions

• It adds or removes angles to the direction of rotation

• It transmits motion through a belt to a recirculating ball gear

What is the advantage of the drive based on an engine of trains of elliptical waves?

• Compact size

• Precise and stable steering

• Regulation of pressure distribution

• Measurement of torque on the steering wheel

How does the elliptical ring gear engage with the cylindrical pinion in the drive based on elliptical waves?

• By rotating in the same direction

• By rotating in opposite directions

• By adding or removing a little twist to the inner cylinder

• By transmitting motion through a belt to a recirculating ball gear

What is the difference between the length of the perimeter of the ellipse and the circle in the drive based on elliptical waves?

• It regulates the pressure distribution

• It measures the torque on the steering wheel

• It adds or removes angles to the direction of rotation

• It adds or removes a little twist to the inner cylinder
