A linear actuator

A linear actuator (1) comprising an electric motor (20), a transmission (40), a spindle (80), a spindle nut (81), a housing (10), an outer tube (3) and an inner tube (2);

• the outer tube (3) being connected to the housing (10);
• the spindle (80) being interconnected to the transmission (40);
• the spindle nut (81) being arranged on the spindle (80);
• the inner tube (2) being connected to the spindle nut (81);
• the spindle nut (81) and the inner tube (2) being guided inside the outer tube (3), wherein
• the transmission (40) including a transmission housing (41), a transmission input end and a transmission output end positioned opposite the transmission input end;
• the electric motor (20) having an output shaft (21) being coaxially connected to the transmission input end of the transmission;
• a coupling (30) including a first coupling part (32) being connected to the output end of the transmission, a second coupling part (34) being connected to the end of the spindle and a coupling member (36) disposed between the first and second coupling parts (32,34) and slidably engaged with the first and second coupling parts (32,34).
