Mechanical steering system

Akshay dhole13mmt1013

Basic parts of steering system:Steering wheel, column and shaft – driver

inputsSteering gear – changes direction – rotating

steering wheel into linear motion.Steering linkage – connects steering gear to

steering armsBall joints – allows movement of steering

components and suspension

Mechanical steering system:

Attaches to steering column and shaft

Have an interference fit on the shaft – very tight fit

May contain an airbag assembly, radio controls, cruise controls, etc

1. Steering wheel, column and shaft – driver inputs

Steering wheel

Contains and supports the steering shaft May have a tilt mechanism and telescoping mechanism

Steering column

Steering column couplers allow pivot points in the column

Like a universal jointLoose or worn couplers will result in a loose steering feel, vibration, noise, or sticky steering feel

The steering gear is a device for converting the rotary motion of the steering wheel into straight line motion of the linkage with a mechanical advantage.

Worm and wheel steering gear Worm and sector steering gear Cam and lever / peg steering gear Re-circulating ball steering gear Rack and pinion steering gear.

Steering Gears

Steering linkage is anything connected to the wheels and the steering gear

Tie rods Steering arms Steering knuckles Ball joints

Steering Linkages

Tie rods are attached to pivot points on each front wheel

The other end is attached to the steering gear or rack

1.Tie rods

•The steering arm is attached to the steering knuckle, which includes the spindle•Used to get proper steering angle during turns

2.Steering arm

Steering knuckle and spindle

Allow suspension movement up and down, as well as turning movement

Located in control arms – in lower, as well as upper control arm if so equipped

Wear items – need replacement periodically

Ball joints
