Thanks for your fast reply, but your answer doesn't help.  
I need to understand what I do.  
1.) I know the servo works fine because I tried it and a nother one as well  
2.) I know that I have more range because I bought some with a bigger range than 180°  
3.) You cant't use the analogWrite. Ok. Still need to know what I am doing. It's a pwm-signal, so why not?

So, I still need to expand the range. Maybe changing the source code of the library? Or is there a nother one?  
Or how can I maybe make the analogWrite secure?

Realy hoping for some way because there must be one!
