Window wiper system for motor vehicle, has mechanism formed of cam, sliding elements, shell forming element, mobile and elastic elements, varying inclination of drive shaft axis based on angular position of main drive shaft about its axis

摘要

#CMT# #/CMT# The system has a main drive shaft, whose rotation axis (A1) is fixed with respect to a bearing body (3). The drive shaft is rotationally driven in the body, by a drive device, for driving a wiper blade-holding arm. A drive shaft (4) extends above the body in direction of the shaft (1) and receives the arm on its upper end (40). A mechanism constituted of cam, sliding elements (6, 7), shell forming element (8), mobile element (9) and spring type elastic element (10), varies the inclination of an axis (A2) of the shaft (4) based on the angular position of the shaft (1) about the axis (A1). #CMT#USE : #/CMT# System for wiping a window of motor vehicle. #CMT#ADVANTAGE : #/CMT# The design of the wiper system permits to efficiently wipe the window of the motor vehicle without using a large number of components, thus simplifying arrangement between the components and reducing cost of the system, and hence obtaining a compact structure of the system. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial perspective view of a wiper system in an end position.
