ABSTRACT:
a linear actuator capable of transmitting tractive forces as well as thrust forces and operating then as a rigid single-piece rod. The linear actuator has two identical actuating belts (1, 1′) with notches on each of their sides (10, 10′; 11, 11′) and provided on one first side (10, 10′) with uniformly spaced blocks (2, 2′) which mesh with drive members (3) such that the two actuating belts (1, 1′) are independent upstream of the drive members (3), whereas downstream of the drive members, they are integrally assembled so as to define a section extending along a straight line wherein the linear actuator operates like a single-piece rigid rod.
