The steering with the electroamplifier is shown on fig. 5.74.,
Principle of action of the electroamplifier of a steering
The additional effort to a steering wheel is created by the electric motor of the amplifier of the steering which action does not depend on car power setting. Management of the electric motor is carried out depending on traffic conditions thanks to what higher is provided, than at hydraulic booster use, adaptability of degree of strengthening, energy consumption decreases. The electroamplifier allows to reduce environmental contamination as in it the liquid is not used, and absence of pipelines and hydrosystem hoses in a motor compartment allows to reduce weight of the car.
The gauge of a twisting moment of the steering wheel, the electroamplifier entering into system, magnetic field change will transform to a signal of a current depending on a difference of an angle of rotation between entrance and target shaft at twisting торсиона.
The steering electroamplifier
(ЭУРУ) it is located in salon and consequently it is protected from pollution, influence of heats (from the engine in a motor compartment) and negative influence of environment.
