Section 7 (Electronics - Design And Function - 4 Of 4): Transmission: Design: Differential
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2013 Volvo C70, 2012 Volvo C70, 2011 Volvo C70, 2010 Volvo C70, and 2009 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.
The differential distributes power equally between the drive wheels, even if they are rotating at different speeds.
The differential consists of the differential housing, large and small side gears, shaft journals and thrust washers.
The differential has 6 gearwheels. The differential housing is completely sealed so that if a drive shaft is removed no dirt can penetrate and no oil can run out.
