Geng Xing-ping · Special Purpose Vehicle · 2009
Analysis current touchdown structure of sweeper brush and pointing out the fact that it is difficult to keep the touchdown pressure of the brush even and uniform when the sweeper cleans up the road, and thus the brush is worn out fast, and cleaning efficiency is low as well; To resolve this problem, one set of pressure testing device is designed between brush and hydraulic motor, which applies mechanical, electric and hydraulic technology to adjusts the touchdown pressure of sweeper brush automatically; Introducing the principle and structure of the touchdown pressure auto-control device of sweeper brush, the calculation method of touchdown pressure and the choice of key components and parts.
