What does a mechanical steering system consist of?
2 Answers
Mechanical steering systems consist of a rack-and-pinion steering mechanism and a hydraulic system. The working principle is: the hydraulic pump provides oil pressure to push the piston, thereby generating auxiliary force to drive the steering linkage and assist in wheel steering. The components of a steering system include: the steering control mechanism, the steering gear, and the steering linkage mechanism. The steering control mechanism is composed of the steering wheel, steering shaft, and steering column. The steering system is a device used to change or maintain the direction of a vehicle's movement or reverse. Its design requirements are: 1. The wheels should rotate around the instantaneous steering center during turns; 2. The steering wheels should have the ability to automatically return to the center; 3. Avoid steering wheel vibration and steering wheel wobble during driving; 4. The steering should be sensitive, with a small turning diameter; 5. Easy to operate; 6. There should be a clearance adjustment mechanism in the steering gear and steering linkage mechanism; 7. The rotation direction of the steering wheel should be consistent with the change in driving direction.
Back when I drove older cars, I often used mechanical steering systems, which mainly consisted of the steering wheel, steering column, steering gear, and steering linkage. The steering wheel is the part you hold, and when you turn it, the motion is transmitted through the steering column, a long rod. At the bottom of the column is the steering gear, commonly of the rack-and-pinion or recirculating-ball type, which amplifies or redirects your turning force. Then comes the steering linkage, including tie rods, drag links, and ball joints, all connected to drive the wheels to turn. This system is simple and reliable but requires regular lubrication of the joints to prevent rust and seizing. If the steering feels stiff, just check for wear in the ball joints. Don’t underestimate these small components—they keep your car’s steering nimble and safe. Classic car enthusiasts know all about these maintenance details.
