The principle of not interrupting the torque during gear changes was evolved originally by optimization efforts inside the powertrain of drones to minimize overall power consumption. Because this invention was also covering larger applications regarding the automotive context, a test bench for an automatic car related switch gear was built up over the last couple of years. Above mentioned principle involves a special formed cogwheel A, which is on the current version able to provide a transmission ratio of n down to n-1 teeth, and another cogwheel B which is literally able to be moved along special formed splines onto the surface of cogwheel A. Shrinking or increasing the amount of teeth within just one cogwheel brings mechanical challenges which can only be solved through enhanced polydimensional path-functions to meet given mechanical constraints and of course a resulting area of uncertainty which must not, under any circumstances, be used by cogwheel B.
Hence, the test bench for cogwheel optimization purposes regarding to the novel Horn-Müller-von der Wense switchgear (HMW) includes beside the switch gear a whole bunch of safety enhancements as well as actuators, computation devices and measurement equipment. Since almost no literature and experiences were available to design such unusual cogwheels, we could only make use of CAD based FEM methods in the first place. To move from here, we decided to establish certain optimization loops where involved cogwheels will be improved over several standardized runs following our own experiences.
For the optimization process we are currently looking for upcoming mechanical engineers, who are highly motivated and not afraid of complex tasks to be solved.
