What Is Steering System?
A steering system is a mechanical system that allows a driver to control the direction and movement of a vehicle. It consists of a steering wheel, steering column, steering gear, and other components that work together to allow the driver to steer the vehicle.
There are several types of steering systems, including rack and pinion, recirculating ball, and worm and sector. These systems use different mechanisms to translate the movement of the steering wheel into movement of the wheels, allowing the driver to steer the vehicle.
Steering systems are an essential part of any vehicle, as they allow the driver to safely navigate and control the direction and movement of the vehicle. They are also important for maintaining stability and handling, as they help to keep the wheels aligned with the direction of travel.
The steering system is a group of components that enable a vehicle to follow a desired path. It consists of linkages, joints, and other parts that work together to allow the driver to control the direction and movement of the vehicle. The primary function of the steering system is to provide the driving force to guide the vehicle, and it converts the rotation of the steering wheel into the movement of the wheels in a way that allows the driver to steer the vehicle effectively. The steering system allows the driver to apply the necessary force to steer a heavy vehicle, and it is designed to allow the wheels to move with the suspension without changing the steering angle. There are two common types of steering systems: rack and pinion and steering box. On larger vehicles, either system can be power-assisted to reduce the effort required to steer, especially at low speeds.
Types of A Steering System
There are few types of steering systems available.
- Rack and pinion
- Recirculating ball
- Worm and sector
- Hydraulic
- Electric
1. Rack and pinion
Rack and pinion steering is a common type of steering system found in many modern vehicles. It consists of a rack, which is a toothed bar that runs parallel to the front wheels, and a pinion gear, which is attached to the steering wheel and engages with the rack. As the steering wheel is turned, the pinion gear rotates and pushes or pulls the rack, which in turn causes the wheels to turn.
2. Recirculating ball
Recirculating ball steering is a type of mechanical steering system that uses a series of balls to transmit the turning force from the steering wheel to the wheels. It consists of a steering gear, which is connected to the steering wheel, and a series of balls that are housed in a ball nut. As the steering wheel is turned, the steering gear rotates the ball nut, which in turn causes the balls to move and transmit the turning force to the wheels.
3. Worm and sector
Worm and sector steering is a type of mechanical steering system that uses a worm gear and a sector gear to transmit the turning force from the steering wheel to the wheels. It consists of a steering gear, which is connected to the steering wheel, and a worm gear and sector gear, which are connected to the wheels. As the steering wheel is turned, the steering gear rotates the worm gear, which in turn causes the sector gear to rotate and transmit the turning force to the wheels.
4. Hydraulic
Hydraulic steering is a type of power-assisted steering system that uses hydraulic fluid to transmit the turning force from the steering wheel to the wheels. It consists of a steering gear, which is connected to the steering wheel, and a hydraulic pump, which is powered by the engine. As the steering wheel is turned, the steering gear activates the hydraulic pump, which pressurizes the hydraulic fluid and transmits the turning force to the wheels through a series of hoses and valves.
5. Electric
Electric steering is a type of power-assisted steering system that uses electric motors and sensors
