In vehicles, the transmission from the steering wheel to the steering the wheels are often carried out by a rack and pinion drive. KISSsoft has the option of using the ZE2019 module in the 7 release Helical gear with rack calculation integrated.
In common, industrial rack and pinion drives, the Angle between pinion axis and rack 90°. However, due to the installation conditions of the machine elements in the vehicle, the axle angle usually has to be between Gear or pinion and rack can be adjusted. This results in one Helical gear pairing, the rack has an infinitely large number of teeth.
The theory of the calculation of a helical gear pair with geometry and strength to Niemann was for Racks expanded. This allows the strength, service life, sliding speeds and efficiency of such a drive to be determined. In a 3D illustration The pairing can be rolled with a thin-walled model and the contact pattern checked.

Just in Automobilearea will be for Steering systems often used such mechanisms. By entering the coefficient of friction and calculating the sliding speeds as well as the forces, the efficiency of the drive can be calculated and optimized.
