Patent attributes
An electromechanical power steering system may include an electric servomotor that has a motor shaft and drives a shaft that meshes with a helical gear. The shaft is disposed in a gearbox housing and rotatably mounted in a bearing assembly. A pretensioning installation, for adjusting engagement between the helical gear and the shaft, resiliently pretensions a movable bearing element of the bearing assembly relative to the gearbox housing. The gearbox housing has a housing portion having first and second contact faces, the normals of which do not intersect. The bearing assembly has a bearing support that forms the movable bearing element and has a lever arm having a free end that extends from a main body of the bearing support and on the gearbox housing lies against the second contact face. The main body has an eccentric cam that on the housing lies against the first contact face.
