The steering is one of the most significant technological advances that have occurred in automotive history. Its main virtue
es que el conductor no debe realizar una fuerza exagerada sobre el volante, lo que permite reaccionar frente a imprevistos y efectuar con facilidad maniobras a bajas velocidades.
El sistema de dirección hidráulica funciona a través de un bomba, que presuriza un fluido líquido y es enviado por tubos y mangueras a la caja de dirección.
En su interior, se ubican sellos que al recibir esta presión impulsan a las varillas de acoplamiento, que unen la caja de dirección con las ruedas. Todo esto se activa únicamente cuando el motor del automóvil está encendido.
Las direcciones hidráulicas comunes poseen mejor control a la hora de estacionarse ya que no demandan esfuerzo alguno, en cambio at high speeds requires greater control of the wheel.
So the challenge for firms was to create a location to be adapted to different driving conditions. One of the first responses to this conflict are the Evo steering systems, which means Electronic Variable Orifice address. This system reduces the pressure that passes through the valve and thus restricting the steering assistance.
After the introduction of this system, GM's Delphi subsidiary created Magnasteer system, built after the Cadillac line. The mechanism takes a strong magnetic field variable, which is located around the steering mechanism.
The magnetic field strength will increase or decrease depending on the requirements of the driver and create adequate resistance to movement direction.
This improves control at high speeds and during heavy traffic, and the magnetic field will decrease or disappear so that the assistance will address your operation smoothly.
Opel Astra model, for example, has a pump driven by an electric motor and forming a single unit with the steering box. The advantage of this system is that it does not need such long tubes or hoses. In addition, assistance is growing in power steering.
