Leitra velomobile redesign

Last crawled date: 1 year, 10 months ago

This is the long promised upload of my final B. Eng. project in the Danish Technical University, apologies for the delay.
************************************************************************
The project centers around a space frame tricycle, much like the original Leitra, with additional features developed to answer perceived shortcomings in the existing vehicle.
************************************************************************
The vehicle features a bent aluminum tube chassis, with four carbon leaf springs, and a platform for mounting electrical assistance hardware (battery, mid-drive motor or controller).
The frame has two seat positions- these were developed around the existing Leitra seat, which was 3D scanned and is included for visualization purposes. The crank mast has three mounting positions and adjusts with the arc slots.
The suspension includes a damper with a wishbone on top and a carbon leaf spring for the bottom. This is in order to include a damping mechanism in the suspension system. I have not been able to find a similar suspension in use in any vehicle currently in production.
******************************************************************************
As can be seen, this project has a way to go, and that is my intention with uploading it here: I wish to receive constructive criticism and spark interest in this field.
I will be presenting my project at the velomobile seminar on the 30th of October in Austria:
