The share of e-vehicles on German roads is growing steadily - with an upward trend. Among other things, electric vehicles offer the advantage that they realize braking via the electric motor. However, there are situations (safety braking, full batteries) in which a mechanical braking system cannot be dispensed with. Due to the nature of the drive unit, there are new requirements for the braking system. These are to be researched in the future on a drive system test bench at IPEK (see figure). Likewise, the interactions with the rest of the system are to be mapped more realistically than before. At present, the test rig is used as a decoupled flywheel mass test rig.

Task

Within the scope of the thesis, concepts for the further development of the TRP (dry friction test rig) are to be developed. This extension should offer the possibility to realistically represent the braking system of a complete e-axis. The aim of the extension is to be able to perform combined braking. This means that the deceleration for braking the flywheel masses is partly provided by the friction system and partly by the e-motor.The developed concepts are to be evaluated and the best selected. The constructive implementation of the selected concept will be the final part of the work.
