Problems solved by technology

Therefore, the inertial force that will cause greater deformation of the piezoelectric element cannot be completely converted into electrical energy without setting the limit stop
[0017] The applicant also noticed that the resonant oscillating mass body described in the patent document US 5941692 must be installed on one side of the wheel, and the axis of the oscillating motion is parallel to the rotation axis of the wheel itself, so that the centripetal force and gravity can cause mass body oscillations, while this constraint is limiting in terms of flexibility in using
[0018] Finally, the applicant also noticed that since all the embodiments in the documents WO 2005 / 067073 and US 5941692 have limit stops, thereby setting constraints, these embodiments have a high efficiency in converting mechanical energy into electrical energy. Little success has been achieved, where the mechanical energy is generated by forces exerted on the tire

Embodiment Construction

[0069] figure 1 A first preferred embodiment of a wheel 1 according to the invention is represented, comprising a tire 2 mounted on a rim 3 .

[0070] The wheel 1 can be mounted on any type of vehicle, eg passenger cars, goods transport vehicles such as trucks / trailers / trucks etc., motor vehicles and the like.

[0071] More specifically, the tire 2 is preferably designed for use in a vehicle provided with on-board electronic means adapted to communicate with other means housed in or located on the wheel 1. Cooperating with, and interacting with, the other means described below will be described.

[0072] The tire 2 comprises a carcass structure 4 . The carcass structure 4 has at least one carcass ply (not shown in detail in the figures), which is designed to be substantially toroidal in shape and which utilizes its opposite circumferential edges and a pair of annular anchoring structures. In conjunction, each anchoring structure is arranged in an area 5 commonly referred to...

Abstract

A wheel for vehicles comprises a rim (3), a tyre (2) mounted on the rim (3), at least one device (17) for energy generation operatively associated with the tyre (2). The device (17) for energy generation comprises a first element (18) that is fixed relative to the rim (3) or to the tyre (2), and a second element (19) mounted on the first element (18) and free to rotate relative to said first element (18) around a predetermined rotation axis (Z). The second element (19) has a mass centre (CG) eccentric to the predetermined rotation axis (Z). The device (17) for energy generation further comprises an electric generator (25) having a stator (26) mounted on the first element (18) and a rotor (27) mounted on the second element (19).

Description

technical field [0001] The invention relates to a wheel for a vehicle. In particular, the invention relates to a wheel provided with means for generating the electrical energy required to power devices mounted in the tire or on the rim of said wheel. Background technique [0002] These devices, for example known as detection units, can monitor the working conditions of the tires (such as pressure and temperature) and are suitable for recording the change history of some parameters representative of the working conditions over time, or these devices can be equipped with There are actuators, such as pumps, which are adapted to keep the pressure in the tire substantially constant. [0003] The parameters that usually need to be considered can be identification code, temperature, pressure, distance traveled by the tire, load, and some parameters (such as force, acceleration, deformation) obtained by mathematical operations, which can be used in tires. within itself. [0004] ...
