MECHANISM OF SUB-ASSISTANCE OF STEERING CONTROL OF WHEELED VEHICLES FOR THE TRANSMISSION, WITH CONSTANT VARIABLE PROPORTION OF MOTION TRANSMISSION BY THE USE OF PLANETS AND GEARS.

摘要

The invention refers to a mechanism of sub-assistance of the steering control of the wheeled vehicles aiming at the constant variable proportion of motion transmission by the use of planets and gears. The mechanism is interpolated between the shaft of the steering wheel (2) and the shaft of the gear rack (3) and its aim is to help the driver during the driving of the vehicle. The change of ratio is achieved by the deviation of the middle rotation shaft (29) of the gears from the middle verticaland the linking of different toothings of the planet gear (13) with the inlet (11) and outlet (14) discs. In order to have this deviation, an electric motor (16) or a hydraulic cylinder of double effect (34) intervenes, that transfers its motion to a control arm lever (23) that provides for its conversion to linear motion.
