Windscreen wipers for an automobile has toothed belt drive coupled to a pair of reciprocating linear actuators

摘要

The front windscreen wipers (12,22) are coupled to pivot points having toothed belt (5) transmission cogs (15,24). The belt connects with a pair of linear actuators (8,9) that each move a specific distance to cause the wipers to move through a controlled arc. A hinged link (26) maintains belt tension. The actuators can be pneumatic and are coupled to a controller.
