Patent ID: 8308603

Claim:
A linear actuator comprising: an electric motor ( 2 ), a gear housing ( 18 ), a transmission comprising a planetary gear ( 4 ) with a sun wheel ( 17 ), a planetary wheel holder ( 13 ) with planetary wheels ( 14 ) in mesh with the sun wheel ( 17 ) and a tooth rim ( 15 ) in the gear housing ( 18 ), where the planetary wheels ( 14 ) are in mesh with the toothed rim ( 15 ); a spindle ( 5 ) in connection with the transmission, a spindle nut ( 6 ) on the spindle, a bearing ( 20 ) for embedding a shaft end of the spindle ( 5 ), wherein the shaft end of the spindle ( 5 ) is lead freely through the transmission and connected to the bearing ( 20 ), and where the connection between the shaft end of the spindle ( 5 ) and the transmission allows a mutual axial movement so that axial forces are only lead through the spindle bypassing the transmission and directly to the bearing ( 20 ).
