  • Electric power-steering gear, in particular for motor vehicles
    Patent number: 6273211
    Abstract: In an electric power-steering gear, in particular for motor vehicles, having a steering shaft (1) which is actuated by a steering wheel and which forms an input for a step-down gear in the form of a harmonic drive (2) and which makes available an output, in the form of a steering element (3), to a conventional steering gear, sensors which output a signal for the steering torque which is applied being arranged on the steering shaft (1) in a known fashion, and said sensors leading, via a corresponding amplifier circuit, to an electric motor (10) which is arranged coaxially with respect to the steering shaft (1) and the steering element (3), the stator of the electric motor (10) is arranged fixed in terms of rotation in the externally toothed flexible rotor (4) and the elliptical driver (6) of the harmonic gear (2) acting, as a result of the elastically deformable, externally toothed flexible rotor (4), with migrating engagement on the internally toothed annular stator (5), which is fixed in position, and the fl
