Rack & Pinion Power Steering


Rack & Pinion steering is steadily becoming the typical kind of steering on cars, small trucks, and SUVs. It is actually a pretty simple mechanism. A rack and pinion gearset is encircled in a metal tube, with each end of the rack poking out from the tube. A rod, called a tie rod, hooks up to each end of the rack.

Power Steering Service for Automobiles


Power Steering Service should be done between 15K to 45K depending on the vehicle, to enjoy a comfortable ride in your vehicle, you need balance, stability and smoothness – your car’s steering and suspension are what make this happen. Steering and suspension are in charge of keeping your wheels firmly in contact with the road and prevent your car from veering to one side of the road.

Power Steering System Pump and Rotary Valve


As the vanes turn, they draw hydraulic fluid from the return line at low pressure and push it into the outlet at high pressure. The amount of flow from the pump often varies based on the engine’s speed. The pump is designed to send a regular flow when the engine is idling. But when engine is running at higher speeds, the pump moves much more fluid than necessary.

Future of Power Steering in Automobiles


You can expect to see innovations that will drastically improve fuel efficiency. One of the coolest ideas being considered iin the future of power steering is a “steer-by-wire” or “drive-by-wire” system. These would take out the mechanical link between the steering wheel and the steering, using a purely electronic control system instead. Basically, the steering wheel would operate like the one you buy for your video games or computer. They all contain sensors which tell the vehicle what the driver is doing with the wheel, and most contain some motors in them to give the driver feedback on what the car is doing. The output of these sensors would control the motorized steering system. This would free up more space in the engine area and reduce vibrations by eliminating the steering shaft.

Recirculating Power Steering


The recirculating-ball steering gear has a worm gear. It helps to think of the gear in two parts. The first part is a metal block with a threaded hole in it. This block has gear teeth cut into the exterior, and these engage a gear that moves the pitman arm (see diagram above). The steering wheel connects to a threaded rod, much like a bolt, that fits into the hole in the block. When the steering wheel turns, it rotates the bolt. Instead of twisting further into the block the way a normal bolt would, this bolt is held fixed so that when it turns, it moves the metal block, which then goes on to move the gear that orients the wheels.
