1. A detection device for a simultaneous detection of normal and tangential components of a force acting in a detection portion at a brake caliper or at a suspension of a vehicle wheel, wherein the detection device comprises:
a plate-shaped casing mainly extending along a reference plane (P), said plate-shaped casing being formed by a first and a second portions constrained and/or welded to each other, wherein the first portion has, towards outside of the plate-shaped casing, a first plane face, parallel to the reference plane (P), adapted to be placed in close contact with said detection portion, and the second portion has, towards outside of the plate-shaped casing, a second plane face parallel to the reference plane (P), adapted to be placed in close contact with fastening and clamping means;
a force sensor assembly, housed in said plate-shaped casing, and mechanically constrained and/or welded to said first portion and second portion of the plate-shaped casing, wherein the force sensor assembly is configured to detect:
a normal force component, in a direction normal to the reference plane (P), transmitted thereto by contact and pressure by the plate-shaped casing, representative of a normal force acting on the plate-shaped casing, and
at least one tangential force component, in at least one respective tangential direction defined by the reference plane (P), transmitted thereto by contact and pressure by the plate-shaped casing, representative of a tangential force acting on the plate-shaped casing, and wherein
the force sensor assembly is configured to generate, by piezo-resistive effect, one or more electrical signals representative of the normal force component and of the at least one tangential force component detected; and
an electrical interface integrated in the plate-shaped casing and connected to the force sensor assembly to conduct and make said one or more generated electrical signals available.
