Abstract
Steering boxes currently available on the market in order to convert the rotation of the steering wheel into the angular rotation of the wheels are not suitable to be partially built into the rim of the wheels of an electric car. In addition, existing boxes do not allow the independent rotation of the wheels or wide turning radii. These limitations are overcome using a system comprising: a body into which at least one motor is built using corresponding supports, which motor(s) actuate(s) the steering rotation axle of each steered wheel in the upper part of the body, and, in the lower part, a transmission gearbox and a stationary circular crown gear with which driving pinions mesh, said pinions rotating about the crown gear, thereby rotating the entire body and the rotation axle of the wheel built into the body together with suitable means.
