DAF unit flag often carried local unit name on the top left, 'Loberich 1' would fit that.
If the cogwheel is in gold rather than black then it would most likely be a flag for 'exemplary National socialist Factories' given out for self-explanatory reasons.
The cogwheel was mostly/mainly used by the DAF but is also seen in a variety of other Nazi organisations symbolism as an accepted part of their 'graphical dictionary'.
Volkswagen:

I'd also make some issue with describing the NSKK as a purely HJ/DJ organisation, since 1930 the NSAK/NSKK provided a valuable group of keen driver/mechanics aged from 18-45 to the Germans, they used many Non-German personnel from occupied countries. One specific branch, the 'Motor HJ' ensured the training of kids, the majority were adult motoring enthusiasts.
Cheers,
Adam.
