This paper presents two wheel body concepts for multi-component gearwheels, consisting of a gear ring and the already mentioned wheel body. Two process chains for manufacturing two wheel bodies are introduced. Additionally, both wheel bodies are investigated numerically. The torque between shaft and gearwheel a multi-component gearwheel is able to transfer is chosen as command variable to be maximized. Finally, both wheel body concepts are compared to each other.

LEIKO is a high voltage connector made of aluminium for electric and hybrid electric vehicles. Substituting copper wires with aluminium wires leads to lighter and more cost efficient automotive car wiring harnesses. Due to the material properties of aluminium compared to copper a new concept for a high voltage connector made of aluminium for aluminium wires was developed. By allocating the topics concept determination, manufacturing technologies and electrical qualification in an interdisciplinary team a well-founded solution meeting the demands of hybrid cars was developed.
