Patent ID: 8662234

Claim:
A drive and steering apparatus for an industrial truck with a drive wheel ( 10 ), which is rotatably suspended in a drive wheel suspension ( 12 ), which is swivel-mounted around a mainly vertical axis, a steering device, which has a handlebar and a bearing component ( 20 ), which is swivel-mounted coaxially or axially parallel to the drive wheel suspension ( 12 ), and a steering wheel control device, which has at least one sensor ( 28 ), which is arranged in a permanent position with respect to the drive wheel suspension ( 12 ) or the bearing component ( 20 ) and captures a differential angle between the drive wheel suspension ( 12 ) and the bearing component ( 20 ), and a steering drive, with which the drive wheel suspension ( 12 ) is pivotable as required by the measured differential angle, wherein an elongated sensor arm ( 32 ) is connected in a torque-proof manner with a sensor shaft ( 54 ) of the at least one sensor ( 28 ) and has a longitudinal axis and a free end facing away from the sensor shaft ( 54 ), and a counter piece, which is arranged in a permanent position with respect to the bearing component ( 20 ) or, respectively with respect to the drive wheel suspension ( 12 ), works together with the sensor arm ( 32 ) such that the sensor arm ( 32 ) with the sensor shaft ( 54 ) is rotated during a relative movement between the bearing component ( 20 ) and the drive wheel suspension ( 20 ).
