Hi Helge,

how about:

\version "2.14.2"

top = \change Staff = "1"
bottom = \change Staff = "2"

musicB = \relative c {
<<
    \new Voice { \voiceOne e''4 e }
    \new Voice { \override Beam #'auto-knee-gap = #1 \bottom c,,8 g'
\top e' c' }
>>
}

\score {
  \new PianoStaff <<

    \new Staff = "1" { \musicB }
    \new Staff = "2" { \clef bass s4 c }

  >>
}
