Abstract

A brush wear adjustment system for use in a powered street sweeper to provide for consistent sweeping performance where wear of rotary brush bristles is constantly sensed and the rotational speed of the rotary brush is automatically increased to maintain a desired bristle tip speed to maintain desirable sweeping attributes. Rotary brush support arm angular displacement is monitored in order for an electro-hydraulic controller to influence rotational speed of the rotary brush and to provide a readout relative to bristle length.
