The Institute for Automotive Engineering at RWTH Aachen University (ika), is currently developing, constructing, and implementing the research vehicle SpeedE as an open research and innovation platform for research and industry. On research focus of the SpeedE concept, amongst others, is the innovative front suspension. Not only is the front axle’s steer-by-wire system able to steer each wheel individually, but it is also able to achieve steering angles of up to 90°. These requirements lead to an unconventional setup of the axle replacing the tie rod and the rack and pinion steering gear of a double wishbone suspension by two steering actuators consisting of an electric motor and a strain wave reduction gear located at the outer kinematic hardpoint of the upper control arm and mounted to the wishbone through a cardan joint.
