Product Description

Chevrolet Captiva Power Steering Rack

1. How does steering rack work

Rack and pinion steering uses a gear-set to convert the circular motion of the steering wheel into the linear motion required to turn the wheels. It also provides a gear reduction, so turning the wheels is easier.

It works by enclosing the rack and pinion gear-set in a metal tube, with each end of the rack sticking out from the tube and connected to an axial rod. The pinion gear is attached to the steering shaft so that when the steering wheel is turned, the gear spins, moving the rack. The axial rod at each end of the rack connects to the tie rod end, which is attached to the spindle.

Most cars need three to four complete turns of the steering wheel to go from lock to lock (from far right to far left). The steering ratio shows you how far to turn the steering wheel for the wheels to turn a certain amount. A higher ratio means you need to turn the steering wheel more to turn the wheels a certain amount and lower ratios give the steering a quicker response.

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.

There are two main types of rack and pinion steering systems:

End take off – the tie rods are attached to the end of the steering rack via the inner axial rods.
Centre take off – bolts attach the tie rods to the centre of the steering rack.

2.How does steering rack work with power steering

When a rack and pinion system is connected to a power steering system, the design changes slightly. A cylinder with a piston in the middle is placed in the rack. There is fluid on both sides of the piston. When pressure is placed on the fluid on one side of the piston, it forces the piston to move, which turns the rack and assists with steering.
