Windscreen wiper arm driving arrangement for car, has driving shaft to rotate angular cogwheel portion that is geared on input pinion rotatably connected to driveshaft, and output shafts axially retracted towards interior in case of impact

摘要

The arrangement (10) has reference pinions (22a, 22b) respectively arranged on end sections of a driveshaft that is rotated around a main axis (B). Output pinions (30a, 30b) are geared on the respective reference pinions. Output shafts (32a, 32b) are mounted in output bearings (34a) in a swiveling manner along output axes (C, D) perpendicular to the main axis. An input driving shaft (16) extends along a driving axis (A) perpendicular to the driveshaft and rotates an angular portion (18) of a cogwheel. The portion is geared on an input pinion (28) rotatably connected to the driveshaft. The output shafts are axially retracted towards interior of a vehicle by respective metal split rings, when the output shafts are subjected to impact.
