Abstract
The invention proposes an electric linear actuator with a take-off element () that is adjustably supported on a main housing () and is connected to and driven by an electric motor () via a spindle drive (). This connection is realized in the form of a purely plug-type coupling () that is formed by a gear transmission (). The gear transmission () comprises a first transmission gear () that forms part of the spindle drive () and a second transmission gear () that together with the electric motor () forms part of a motor module (). When the motor module () is attached or removed, the teeth of the gear transmission () are disengaged or disengaged automatically.
