Fully and Semi-Automatic Wheel Alignment in the Assembly Line and at the End-Of-Line

FULLY AND SEMI-AUTOMATIC WHEEL ALIGNMENT IN THE ASSEMBLY LINE AND AT THE END-OF-LINE

WHEEL ALIGNMENT STAND IN THE ASSEMBLY LINE - PASSENGER CAR

To reduce the necessary test and adjustment capacities at the end of line the wheel alignment stand in the assembly line offers an adequate alternative to conventional transit test stands. With this system the wheel geometry of the vehicle is mea- sured and adjusted fully-automated directly after the ins- tallation of the axles in the chassis. »» Wheel alignment stand in the assembly line During the adjustment the vehicle is suspended from its hanger. According to the vehicle type the adjustment of toe and camber values at the front axle as well as at the rear axle is carried out by the setting tools developed by Dürr. Robots deliver the setting tools exactly to the respective setting points. The test stand control and visualization is effected by the x-line software developed by DÜRR.

SEMI-AUTOMATIC TOOLS TO ADJUST THE REAR AXLE - PASSENGER CAR

The semi-automatic setting tools to adjust and lock the »» Toe setting tool front axle toe can be integrated in the wheel geometry test stand x-wheel. In this application the tools to adjust the toe of the rear axle are automatically prepositioned according to the chassis geometry (type/track width/wheel base). The final delivery to the corresponding bolting points and the toe setting of the rear axle are executed manually by the operator.

Afterwards, the bolting is executed torque and angle controlled. The actual values achieved are documented and saved. The test stand control and visualization is effected by the x-line software developed by DÜRR. »» Toe setting tool rear axle

Afterwards, the tool units are manually and precisely positioned and the power-assisted adaptation of the spindles to the bolts on the pedestal is performed. »» The toe setting is realized through y-movement of Spindle the trailing arm pedestal by means of an eccentric. »» After the setting, the three bolts are tightened (torque controlled) to the final torque.

* The photographs and figures of the assembly and testing systems in this flyer are not showing the complete installations. The requirements of the machinery directive (2006 / 42 / EG) will only be met by other supplementary scope of supply or - on delivery of uncompleted machines - those requirements must be fulfilled by the manufacturer of the (complete) machine.
