A gearwheel in a reduction drive in a windscreen wiper for a motor vehicle, comprises a split gearwheel for taking up play in the system and acting as a damper

摘要

The drive gear consists of two gear wheels, the first (20) connected to the drive shaft (6) and the second (22) connected to the first via a damping system (32), which allows some relative radial movement between the teeth of the adjacent gears (20,22). The teeth of these two gears engage with the teeth of the gearwheel (26) of the driven gear (4) so that in the drive mode, the play between the gear teeth is taken up.
