The images you provided illustrate the inner workings of two types of steering systems commonly used in automobiles:
1. Rack and Pinion Steering
* How it works:
* When the steering wheel is turned, it rotates the pinion gear.
* The pinion gear meshes with the rack, causing it to move left or right.
* The rack is connected to the tie rods, which in turn move the steering knuckles and ultimately the wheels.
* Key Components:
* Pinion Gear: Rotates in response to steering wheel input.
* Rack: Linearly moves in response to pinion gear rotation.
* Tie Rods: Connect the rack to the steering knuckles.
* Steering Knuckle: Converts linear motion of the tie rod into wheel rotation.
2. Conventional Steering (Parallelogram Steering)
* How it works:
* The steering wheel turns the steering shaft.
* The steering shaft rotates the worm gear.
* The worm gear meshes with the sector gear, causing it to rotate.
* The rotation of the sector gear moves the pitman arm.
* The pitman arm is connected to the steering linkage, which ultimately turns the wheels.
* Key Components:
* Steering Shaft: Connects the steering wheel to the gearbox.
* Worm Gear: Rotates in response to steering wheel input.
* Sector Gear: Rotates in response to the worm gear.
* Pitman Arm: Connects the sector gear to the steering linkage.
* Steering Linkage: A series of components (idler arm, center link, tie rods) that transmit motion from the pitman arm to the wheels.
In summary:
* Both systems convert the rotary motion of the steering wheel into linear motion to steer the vehicle's wheels.
* Rack and pinion systems are generally considered more efficient and precise due to their simpler design.
* Conventional steering systems were more common in older vehicles.
