A transmission for means of transport comprising: - a driving shaft suitable for being positioned on the axis ("X") of a driving force; - an intermediate shaft comprising at least one first transmission unit, the first transmission unit being driven to rotate by a gearwheel fixed on the driving shaft; - a rigid supporting element structured for forming at least one fixed support for at least the intermediate shaft, wherein the intermediate shaft can rotate relative to the fixed support; - a measuring element comprising a first portion with controlled deformation because having predetermined mechanical yielding characteristics when it is stressed by the force transmitted from the driving shaft to the intermediate shaft; said first portion forming at least one mobile support for the intermediate shaft, wherein the intermediate shaft can rotate relative to the mobile support; and a second supporting portion interposed between the first portion and the rigid supporting element; the first portion with controlled deformation and the supporting second portion being connected to each other by a shared portion; said measuring element having at least one slot extending around an axis of extension ("R") of the measuring element coaxial with the axis ("Y") of the intermediate shaft; the measuring element comprising a strain gauge able to convert a movement between the first portion with controlled deformation and the second supporting portion into a value of the mechanical force; the electrical strain gauge being applied on the shared portion; - a projection, extending from one portion (71, 72) towards the other portion (72, 71) of the measuring element, defining a stop to avoid excessive inclination of the driving shaft relative to the intermediate shaft in such a way that the controlled deformability of the measuring element is such as to allow an approach of at least one portion of one of lateral surfaces (74a, 74b) of the slot to the projection when the mechanical force applied between the driving shaft and the intermediate shaft is such as to contrast at least partly a predetermined stiffness of the measuring element. - a driving shaft suitable for being positioned on the axis ("X") of a driving force; - an intermediate shaft comprising at least one first transmission unit, the first transmission unit being driven to rotate by a gearwheel fixed on the driving shaft; - a rigid supporting element structured for forming at least one fixed support for at least the intermediate shaft, wherein the intermediate shaft can rotate relative to the fixed support; - a measuring element comprising a first portion with controlled deformation because having predetermined mechanical yielding characteristics when it is stressed by the force transmitted from the driving shaft to the intermediate shaft; said first portion forming at least one mobile support for the intermediate shaft, wherein the intermediate shaft can rotate relative to the mobile support; and a second supporting portion interposed between the first portion and the rigid supporting element; the first portion with controlled deformation and the supporting second portion being connected to each other by a shared portion; said measuring element having at least one slot extending around an axis of extension ("R") of the measuring element coaxial with the axis ("Y") of the intermediate shaft; the measuring element comprising a strain gauge able to convert a movement between the first portion with controlled deformation and the second supporting portion into a value of the mechanical force; the electrical strain gauge being applied on the shared portion; - a projection, extending from one portion (71, 72) towards the other portion (72, 71) of the measuring element, defining a stop to avoid excessive inclination of the driving shaft relative to the intermediate shaft in such a way that the controlled deformability of the measuring element is such as to allow an approach of at least one portion of one of lateral surfaces (74a, 74b) of the slot to the projection when the mechanical force applied between the driving shaft and the intermediate shaft is such as to contrast at least partly a predetermined stiffness of the measuring element.
