Abstract
A dynamometer link comprises a first transmission member adapted to slide axially relative to a second transmission member with spring means disposed between the first and second transmission members. Relative displacement of the two members is amplified by a lever pivotally mounted on one of the two members and on which the other member operates. The lever comprises at least a radial arm articulated to one of the members and comprising at a distance from the articulation a two-way axial coupling to the other member and an axial arm having a free end on respective sides of which are disposed two detector members. The link is able to determine the direction of the force transmitted by the link.

Dynamometer link for transmitting an axial tensile or compressive force, comprising:
- two transmission members adapted to slide axially relative to each other;
- spring means disposed between said transmission members so as to be elastically deformed by any relative displacement of one member relative to the other from a rest position, due to said forces;
- a lever comprising a radial arm coupled through hinge means to one of said two transmission members and maintained against the other of said two transmission members, and an axial arm having a free end, a relative displacement of said two transmission members driving said lever in rotation about a rotation axis and generating an amplified displacement of the free end of said lever;
- and
- two detector members disposed respectively close to two opposite sides of said free end in a plane perpendicular to said rotation axis, each detector member being assigned to detect a rotating motion of the free end of said axial arm in a respective direction corresponding to a direction of said force.
Dynamometer link for transmitting an axial tensile or compressive force, comprising:
- two transmission members adapted to slide axially relative to each other;
- a lever comprising a radial arm formed by a radial plate made from an elastically deformable material fastened to one of said two transmission members and coupled to the other of said two transmission members, said radial arm having a central part to which is rigidly fixed an axial arm having a free end, a relative displacement of said two transmission members driving said lever in rotation about a rotation axis and generating an amplified displacement of the free end of said lever;
- and
- two detector members disposed respectively close to two opposite sides of said free end in a plane perpendicular to said rotation axis, each detector member being assigned to detect a rotating motion of the free end of said axial arm in a respective direction corresponding to a direction of said force.

- two transmission members adapted to slide axially relative to each other;
- spring means disposed between said transmission members so as to be elastically deformed by any relative displacement of one member relative to the other from a rest position, due to said forces;
- a lever comprising a radial arm coupled through hinge means to one of said two transmission members and maintained against the other of said two transmission members, and an axial arm having two axial portions offset relative to each other in a plane perpendicular to a rotation axis of said lever, a relative displacement of said two transmission members driving said lever in rotation about a rotation axis and generating an amplified displacement of the two axial portions of said lever;
- and
- two detector members disposed respectively close to said two axial portions in a plane perpendicular to said rotation axis, each detector member being assigned to detect a rotating motion of one respective of said two axial portions in a respective direction corresponding to a direction of said force.
Dynamometer link for transmitting an axial tensile or compressive force, comprising:
- a male transmission member adapted to slide axially inside a female transmission member;
- spring means disposed between said male and female transmission members so as to be elastically deformed by any relative displacement of one member relative to the other from a rest position, due to said forces;
- a rigid L-shaped lever located inside the female member and comprising an axial arm having a free end and linked through a cranked portion to a radial arm having a free end coupled without play through hinge means to said female transmission member, said cranked portion being maintained with a slight radial play against the male transmission member, a relative displacement of said two transmission members driving said lever in rotation about a rotation axis and generating an amplified displacement of the free end of said axial arm;
- and
- two detector members disposed respectively close to two opposite sides of the free end of said axial arm in a plane perpendicular to said rotation axis, each detector member being assigned to detect a rotating motion of the free end of said axial arm in a respective direction corresponding to a direction of said force.
