Dear [FIRSTNAME],
Transmissions for electric cars are much simpler in design than for conventional combustion engines, but place far higher demands on the manufacturing precision of the gears used. Thanks to completely new procedures for quality assurance directly in the final machining process, which is gear grinding, these specifications can also be met in series production. |

Intelligent generating grinding
All-electric vehicle drives usually make do with two-stage, non-shiftable transmissions. You would have thought that this would greatly simplify production. After all, this type of transmission design has just four gears, distributed between the drive shaft, the second stage with fixed gear and intermediate shaft, and the axle drive gear. But
in reality, it’s not that simple: first of all, engine speeds are much higher for the e-drive than for combustion engines, at up to 16,000 rpm. This means electric motors
deliver an almost constant torque over a wide speed range. Unlike combustion engines, it is applied to the transmission right from zero speed.

Laser applications for electromobility
The importance of laser welding in car manufacturing has been increasing significantly for years, and not just in car body production. Many components under the hood or, more accurately, in the drive train – benefit from the precise and fast process. Laser welding is likewise increasingly used in the manufacture of electric motors, for example with copper or aluminum compounds, especially in the electric drive and in the battery. More...
