POWER STEERING SYSTEM FOR AUTOMOBILES

摘要

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.

主权项

1. A power steering system for automobiles using motors to increase the torque supplied by the driver to the steering axle and steering wheel to vary the longitudinal inclination of the steered wheels (rim and tyre) , wherein this system comprises a body to which one or more motors are attached by their corresponding supports, which move the pivoting axle for steering each steered wheel, acting as such a shock absorber, one end of which pivots on the first suspension arm, while the opposite end fits to the body at its upper part and solidly to the lower part of the body on a transmission gearbox, a fixed circular crown gear to which the driving pinions mesh, fitted by appropriate means to the ends of the shafts of each motor, the crown gear being fixed to the lower cover of the transmission gearbox with the pinions rotating round the crown gear, making the entire body and turning axle of the wheel turn incorporating the necessary means in the body.
