Rampa auto spare parts sells Lemforder and Moog brand steering heads. The company has more than 200 references managed in stock and many more on order. Steering heads are joints that are used in transverse tie rods and coupling bars to transmit force to the various components and compensate for movement. They are very important components for the safety of the vehicle and must be chosen among first quality ones.
All steering heads feature:
A full range of chain size and teeth numbers to ensure the optimum ratio.
CNC machined chain sprockets and matching chain,
Sealed stainless steel deep groove bearings to ensure low friction, smooth quiet running.
All aluminium parts are anodised in our in-house anodisation plant to ensure quality and prevent corrosive action.
Before we head into the explanation there are currently two major types of the steering system. The commonly used Rack and Pinion System and the conventional system know as the Recirculating Ball Steering System. We will explain both in brief and also how the power-assisted steering system works which is commonly called the power steering.
The most common steering system, the rack and pinion gets its name from the two gears it uses, the rack (the linear gear) and the pinion (circular gear). This system is used in most cars and is usually not employed in heavy-duty vehicles. Its working may appear complex but uses quite simple physics.The steering wheel has a shaft attached to it and on the other end of the shaft is the pinion. The pinion is positioned on top of the rack and moves when the steering wheel is moved. The end of the rack has something called a tie rod. The tie rods connect to the steering arm which in turn is connected to the wheel hub. Onwards to the working of rack and pinion.
The power steering adds some more parts to the rack and pinion system which makes it easier to use. Mainly the pump, pressure tubes, rotary control valve, fluid lines and a hydraulic piston. The job of the pump is to as you might have guessed, pump the fluid around when needed. The rotary control valve ensures that the movement of fluid is only performed when the driver is actually steering the car. The hydraulic piston moves around depending on which fluid line brings the high-pressure fluid. This piston movement on the rack makes it easier for the driver as it is applying most of the force necessary to steer the car. This concludes the brief discussion on how a hydraulic power steering system works.
