What is variable ratio steering?

Variable-ratio steering is a system that uses different ratios on the rack in a rack and pinion steering system. At the center of the rack, the space between the teeth are smaller and the space becomes larger as the pinion moves down the rack.

How do I know if my VW has variable ratio steering?

#Look at your Service Parts Identification label. If this pump stays in the same place even with an accelerated engine RPM, that means your vehicle is aided with variable-assist power steering. Furthermore, try checking out the area that remains under the lid of the trunk.

What is a disadvantage of a fixed ratio steering system?

A disadvantage of a fixed-ratio system is that towards the lock positions, more effort is needed by the driver. This is because of the reduction in the angle of the steering arms that reduces the effective length, and which further reduces the leverage on the wheels.

Why is variable pitch rack and pinion used?

Some cars use variable ratio steering. This rack and pinion steering system uses a different number of teeth per cm (tooth pitch) in the centre than at the ends. The result is the steering is more sensitive when it is turned towards lock than when it is close to its central position, making the car more maneuverable.
