The steering wheel is connected to a steering gear that turns the car’s axles. There are different types of steering, including rack and pinion, manual, and power steering. Failure of the steering gear can cause dangerous situations.
In a car, a steering wheel manages the directional movement of a vehicle. This wheel is connected to a special bar, which uses a steering gear to turn the axles of the car. When the handwheel is turned, the rod turns the gear, which then pulls or pushes the shaft in the required direction.
The steering gear design was first created using Ackermann’s steering geometry, which forces the wheels to turn based on a bar-and-gear design. This design is necessary to ensure that both wheels are rotated simultaneously by the same distance. The gear, which resides in the gearbox, moves the shaft rod horizontally according to the rotation of the flywheel.
There are many forms of steering available in automobiles today. These include rack and pinion steering, manual steering, and power steering. Each form of steering requires a steering gear to manage the car’s directional changes. This gear is usually encased within a gearbox that provides lubricant for the steering arm area.
Manual steering was the first form of steering in automobiles. This type of steering required a large steering wheel to assist the driver in manually moving the car’s steering gear and front wheels. Manual steering was a tedious task for many people because the wheels were difficult to turn on heavy cars.
Power steering was first introduced on the 1951 Chrysler automobile. This steering system uses a special power steering pump that assists the driver in turning the wheels through the steering gear. Power steering is based on a pulley transmission that is connected to the vehicle’s engine. This belt helps move the steering rod when the driver turns the steering wheel.
Rack and pinion steering is usually seen in sports cars. This type of design provides more direct steering over the wheels. A rack and pinion design uses a pinion gear that is attached to the steering shaft of the wheel. This pinion gear moves the rack horizontally, causing the wheels to turn left or right.
When a steering mechanism fails, it causes the vehicle’s wheels to spin freely without control from the steering wheel. This is a dangerous situation that usually occurs when the steering gear wears out. The most obvious sign of gear failure is reduced wheel movement with steering wheel turns. If this happens during driving conditions, the operator should reduce speed as quickly as possible.
