Title: Wheel mounting for front wheel drive car - with asymmetric chamber mounting to offset different lengths of drive shafts
Inventor: SCHNEEWEISS MANFRED
IPC: B60G3/24
Filed: 1975-11-13
Abstract: The front wheel drive transmission has different lengths of drive shaft (4, 5) from the off centre mounted differential (2). This can lead to asymmetric steering, with the car pulling to the side of the shorter drive shaft, as suspension movements cause a greater angular deflection on that drive shaft. To counteract this the camber angles of the two wheels are set at different spacings from the centre of the wheels. The wheel driven by the shorter drive shaft has its camber angle offset more, so that the perpendicular distance between the camber angle and the centre of the wheel is greater than that of the other wheel. This leverage counteracts the tilting effects of the drive shafts.
