Embodiment Construction
[0048] refer to Figure 1 to Figure 7 , the detection device 1 is now described, which is used for simultaneous detection of the normal component and the tangential component of the force acting in the detection portion Z at the brake caliper 100 of the wheel or at the suspension 200 .
[0049] The device 1 comprises a plate-like housing 2 , a force sensor assembly 3 and an electrical interface 4 .
[0050] The plate-shaped housing 2 mainly extends along the reference plane P (in figure 2 In is indicated as the plane relative to which the top view of the device is shown; as detailed below, the resulting tangential forces lie on plane P).
[0051]Such a housing 2 is formed from two parts constrained and / or welded to each other. The first part 20 has a first planar surface parallel to the reference plane P towards the outside of the housing, which is suitable to be placed in contact with the aforementioned detection part Z (which for example belongs to a brake caliper, or whi...

A device is described for the simultaneous detection of the tangential and normal components of a force acting at a brake caliper or suspension of a vehicle wheel. The detection device 1 comprises a plate-shaped casing 2 which contains a force sensor assembly 3 configured to detect both a normal force component fn, and at least one tangential force component ft, and is configured to generate, by the piezo-resistive effect, one or more electrical signals SA, SB representative of the normal force component fn and of the at least one tangential force component ft detected. The device 1 further comprises an electrical interface 4 integrated into the casing 2 and connected to a biaxial force sensor 3 to conduct and make the one or more generated electrical signals SA, SB available. A device and a system are further described for determining a braking force and / or torque due to the action of a vehicle brake caliper, comprising, inter alia, the detection device, and a brake caliper system with a braking force estimation function, employing the devices. Corresponding methods are further described for simultaneously detecting the tangential and normal components of a force acting at a brake caliper of a vehicle wheel or of a force exchanged between an axle and a suspension of the wheel, and to determine a braking force and / or torque due to the action of a vehicle brake caliper.
