Motor vehicle's window wiping system, has control units that respectively control translation and rotational movements of rod in independent manner, where units are respectively constituted by cam profiles and control components

摘要

#CMT# #/CMT# The system has a control unit constituted by a cam profile (51), a control component (70) and a conversion mechanism (7) to control pantograph kinematics by providing translation movement to a primary rod (2) along longitudinal axis (R). Another control unit is constituted by another cam profile (50) and another control component (20) to control rotational movement of the rod to authorize variation of angle of incidence of a wiping brush. The profiles are in a form of through groove. The units respectively control the translation and rotational movements of the rod in an independent manner. #CMT#USE : #/CMT# System for wiping window of a motor vehicle, for a windscreen of complex surface e.g. panoramic windscreen. #CMT#ADVANTAGE : #/CMT# The cam profiles allow the wiping system to be compact and simple to use. The wiping system varies the angle of incidence of the brush in a simple manner. The control units respectively controls the translation movement and the rotational movement of the primary rod in the independent manner, thus providing optimized brush control according to the type of surfaces to be wiped, and hence improving the quality of the wiping. The system decouples the pantograph kinematics of the rotation movement of the principal rod to act independently on the angle of incidence of the brush or on the orientation of the brush, or on both the angle of incidence and the orientation of the brush, using an optimized number of parts. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial, exploded bottom view of a window wiping system.
