Parallelogram Steering and Rack & Pinion Steering Systems

Ball joint movement facilitation

• Enables movement with suspension and steering.

• Restricts movement to a single plane.

• Enhances stability during acceleration.

• Allows for rotational movement only.

Hub Assembly Function

• Holds the wheel bearing and wheel, enabling the vehicle to steer.

• Supports the engine and transmission components.

• Provides power to the vehicle's electrical systems.

• Enhances the vehicle's aerodynamics for better fuel efficiency.

Steering arm (track rod)

• The steering arm connects the steering wheel to the brakes.

• The steering arm threads into the steering rack at one end, and the track rod is fitted to the other.

• The steering arm is responsible for the vehicle's acceleration.

• The steering arm is used to control the vehicle's speed.

Components of a dismantled track rod end assembly.

• A dismantled track rod end assembly.

• A complete track rod end assembly.

• A track rod end assembly with additional parts.

• A track rod end assembly without any components.

Role of the Nut in Steering Box

• Engages a sector shaft that connects to the steering linkage.

• Provides lubrication to the steering mechanism.

• Acts as a safety lock for the steering wheel.

• Adjusts the tension in the steering column.

Steering Box (Recirculating Ball)

• A type of steering system used in modern electric vehicles.

• A conventional steering system used in older and many light/heavy vehicles.

• A steering system that uses hydraulic fluid for assistance.

• A steering system primarily found in sports cars.

trackrod End

• A component in both steering systems that connects the steering linkage to the wheel hub.

• A type of tire used in racing vehicles.

• A part of the engine that regulates fuel flow.

• A device used to measure tire pressure.

Issues associated with the steering column.

• Worn bearings causing noise/play

• Steering wheel color fading

• Column not secure

• Excessive play in joints

Lock nut role in tracking

• Locks the thread to adjust toe in/toe out.

• Prevents wheel slippage during turns.

• Enhances fuel efficiency by reducing drag.

• Improves braking performance by stabilizing the axle.
