Draw bar controlled industrial truck, has elastic rolling members provided in roller bearing for producing braking torque that acts against rotating movement of roller bearing, where rolling members are made of plastic material

摘要

The truck has a drawbar bracket (2) movably supported at a drive carrier (6) over a roller bearing (3) i.e. ball bearing. A sensor i.e. potentiometer, detects alignment of the drawbar bracket relative to the drive carrier, and elastic rolling members are provided in the roller bearing for producing braking torque that acts against a rotating movement of the roller bearing. The rolling members are made of elastic deformable plastic material i.e. polyurethane, where shore hardness of the plastic material is 95. The drawbar bracket is firmly connected with an outer ring of the roller bearing.
