A differential enables speed compensation between two driven wheels of an axle. Regardless of the type of drive, differentials are always required when one motor is used per driving axle. A differential consists of a differential case, two side bevel gears, at least two pinion bevel gears, a pinion shaft and the adjusting and thrust washers. Usually, a spur gear is used as the final drive gear for electric axles. With its extensive experience in the development of all components of a differential, Musashi is very well equipped for the changes in drive technology as a supplier of the complete system with a high level of vertical integration.
Forged differential cases are used when particularly high demands are placed on the material that cannot be met by cast iron. Until now, these were mainly used in trucks. Due to the constantly increasing power density required of differentials, Musashi Europe sees a trend towards the use of steel differential cases in passenger cars as well. Musashi has been working on new developments in this area for some time to continue to be well equipped for the transformation to electromobility in the future.
