<p>The invention concerns a crank-type endless transmission (1, 2) without neutral gear indication, said cranks (1, 2) being rotatable about a first geometrical axis (D) constituting the pivot axis of at least a shaft (5) called crank web bearing shaft. Said transmission is characterised in that the crankarms are of constant length and the angular offset produced on either side of an equilibrium position aligning the crank webs (1, 2) is provided by a single dog (6) in a guide path (8) mounted integral in rotation with at least a portion of the shaft (5) called crank web bearing shaft, said dog (6) being secured to a rotary component (7, 7A) about a second geometrical axis parallel and non merging with the first geometrical axis (10).</p> |
