Attachment device between plate brush and rotating drive head of street sweeper - has bayonet connectors between plate body and drive head, using clamp of threaded shaft and corresponding nut within bayonet hole

摘要

A bayonet connection attaches the collar (4) of the plate body (3) to the drive head (1) by several bayonet connectors (6) spaced around the circumference of each. There is a clamp (7), made up of a nut (16) on a shaft (15), within each bayonet connection to axially press the plate body and drive head together. The collar of the plate body is formed as a spring disc to elastically shape the plate body around the clamp. The threaded shaft is welded onto the plate body and the nut is then non-rotatably fixed onto the shaft. ADVANTAGE - Provides for easier assembly.
