This STIWA machine assembles and tests energy-saving steering gears for trucks. The electro-hydraulic systems are manufactured in 13 variants for left-hand and right-hand drive vehicles and are intended to enable autonomous driving in the future.
Pre-assembled components such as the servo motor and heavy individual parts are fed into the machine for processing. Fully and partially automated stations handle complex processes such as drilling, pinning, precise ball insertion of the spindle, and screwing processes with torques of up to 700 Nm. Vision inspection, determination of friction coefficients, and calibration processes ensure the functionality of each gear.
ERGONOMIC AND SAFE HANDLING OF HEAVY COMPONENTS
Due to the heavy weight of the product parts, which can weigh up to 90 kg, the manual workstations are equipped with special lifting and assembly aids. This enables safe and ergonomic working conditions for operators during complex manual joining and screwing processes.
INTEGRATION OF NEW, HIGH-PRECISION TECHNOLOGIES
Innovative core processes such as drilling and pinning of the spindle with the input shaft or the ball insertion of the spindle into the bearing are essential parts of this machine. The leak test and filling of the steering with filtered, degassed hydraulic oil are carried out in an automated process.
