What Components Make Up the Power Steering System?

Car steering system's function is to allow the driver to control the vehicle's direction and maintain stable straight-line driving. The vehicle's steering system generally consists of a steering gear and a steering linkage mechanism. Here is more information about the steering system: 1. The steering gear is composed of main components such as the steering wheel, steering shaft, steering worm, and sector gear; the steering linkage mechanism includes components like the steering pitman arm, steering drag link, steering knuckle arm, left and right steering tie rod arms, and steering tie rod. 2. The steering gear is divided into two parts: the steering column and the steering meshing mechanism. The main function of the steering column is force transmission and safety protection; the steering meshing mechanism's role is to increase torque and transmit steering force to the steering linkage mechanism. 3. The function of the steering linkage mechanism is to transmit the force from the steering meshing mechanism to the front wheels to achieve steering.
I've repaired quite a few cars and encountered many cases of heavy steering. The power steering system generally consists of a steering wheel and steering column, which directly affect the driver's feel. The key lies in the power assist mechanism. In hydraulic systems, this includes a pump, reservoir, and pipelines that use oil pressure to drive the gearbox; electric systems use motors and ECUs for control, eliminating the need for fluid. Other critical components like the rack-and-pinion gearbox determine wheel turning angles. Common issues often stem from oil leaks causing pump failure or electrical shorts disabling the motor. I recommend checking power steering fluid levels every three months - don't wait until steering suddenly becomes heavy during driving, especially dangerous during turns or high-speed maneuvers. Using high-quality fluids and regular maintenance can prevent costly major repairs.
After driving for several years, my old off-roader once experienced power steering failure. The system is actually quite simple: the steering wheel is connected to a steering column, with a power assist mechanism at the base—either a hydraulic pump with a fluid reservoir or an electric motor with a computer module. They amplify the force through a gearbox, making steering much easier. I had a failure on a mountain road, and it felt like aging pipes or fluid leakage. Normally, you can tell if it's working by checking the steering wheel's resistance. If you're driving a new car, the electric version is more reliable and fuel-efficient, but repairing a faulty motor can be more expensive. Safety first—if the steering feels off, stop and check immediately to avoid accidents. Regular maintenance can extend its lifespan; don't skimp on small costs and risk bigger problems.
I'm passionate about car modifications, and the power steering system is incredibly fun! It consists of the steering wheel input shaft, steering column, and then the core power-assist components: in the hydraulic era, there were pumps and oil tanks; nowadays, electric vehicles are popular with electric motors plus sensors, and the ECU intelligently adjusts resistance. The gear system is also essential for controlling wheel steering. When working on cars, I've found that the electric version is quieter and more flexible, and can even integrate with driving assistance. But don't overlook the details—wiring and connectors often cause issues. Adding an extra cooling kit can improve durability. Driving and feeling the changes brings a lot of joy.
