Abstract
The invention relates to a method for relative driving of bodies on the basis of electromagnetic or piezo-electrical conversion of electricity into energy and/or movement. Use is made of intermediate bodies for the conversion into mechanical energy. The invention also relates to a linear drive assembly for a shaft or other elongate body, with engaging means for co-displacing engagement of the shaft and the like, as well as displacing means forming a moving whole with the engaging means for displacing the engaging means in driving direction between a non-engaging or slipping position and an engaging or shaft-co-displacing position. Means are further provided for displacing the displacing means in driving direction. In addition, the invention relates to a device comprising two drives assemblies according to the invention, wherein the drive assemblies are disposed for moving the shaft in opposite directions.
