Abstract:
Assembly (10) including a wheel (12) and a tire (14), wherein the assembly comprises passive deflation means (20) for the tire (14). These means may be a porous zone of the tire or of the wheel, and may also comprise a deflation valve which is inactive below a predetermined pressure threshold.
Abstract:
Wheel for an automobile, in which assembly between the sheet metal disc and the wheel rim is effected under the outer seat of the rim by cylindrical fitting.The profile of the rim may be obtained by a flow spinning process.
Abstract:
A vehicle wheel comprises a rim and a disk, the disk presenting a generally flat center zone of attachment of the disk to the vehicle, a zone of connection of the disk and the rim and an intermediate zone. The intermediate zone of the disk includes a given angular sector, or two diametrically opposite angular sectors, stiffened against axial bending relative to any other angular sector of the same central angle.
Abstract:
A magnetic encoder ring formed of a toothed annular metal disk with a concentric thermoplastic ring cast around the toothed annular metal disk.
Abstract:
A multipolar magnetic ring is fomred by joining together two rings having the same geometry and magnetic characteristics. The coaxial rings have circumferentially spaced apart teeth which form identical magnetic poles. The magnetic poles of each ring are embedded into the spaces separating the magnetic poles of the other ring. The magnetic poles of each ring have the opposite polarity to the polarity of the adjacent poles of the other ring.
Abstract:
Wheel disc, including a radially outer circular mounting part, a radially inner fixing and centering part with a bearing region comprising a specified number of fixing apertures and ending radially inwardly with a centering aperture, and spokes connecting the inner and outer parts. Each spoke is disposed substantially circumferentially between two adjacent fixing apertures and the radially inner free edges of the radially outer circular part defining perforations with the free lateral edges of the spokes. In order to mechanically reinforce each spoke, the central region of each spoke is deformed in order to house a swelling receding axially outwardly relative to the lateral regions of the spokes, including a yoke opening into the centering aperture.
Abstract:
A device for detection of the speed of rotation of a rolling bearing which has an encoder element mounted on the rotating part of the bearing and a sensor unit consisting of a sensor holder attached to a support mounted in contact with a nonrotating part of the bearing. The sensor unit is mounted on an elastic member for positioning with respect to the encoder element and may be adjusted with respect to a removable immobilization component of the sensor unit in contact with the support.
Abstract:
An antifriction bearing assembly comprises a stationary outer race and a rotatable inner race with two annular rows of rolling elements between the races. A sensor assembly is mounted in the outer race so as to position a sensor between the races and the two rows of rolling elements, and an encoder is mounted on the inner race between the rows of rolling elements. Several sensor assembly and encoder configurations are included.
Abstract:
A bearing assembly comprises an outer race with an outwardly projecting flange and an inner race with a similar outwardly projecting flange. A sensor assembly is mounted on the flange of the stationary race, and an encoder is mounted on the flange of the rotating race. Several sensor assembly and encoder configurations are included.
Abstract:
The pressure of a vehicle tire fitted on a vehicle wheel is measured and regulated, utilizing a source of compressed air, a check valve leading to an interior of the tire, and an air feed circuit connecting the air source to the check valve. Compressed air is fed from the air source into the circuit and against the check valve to tend to open the check valve. A pressure drop is imposed at a point in the circuit, wherein a resulting pressure drop in the circuit downstream of such point and upstream of the check valve is less than 10% of the pressure drop at the point. A measurement is made of the pressure in the circuit at a location downstream of the point, or in the tire itself. The evolution of the pressure measured in step D is analyzed as a function of time, to determine whether the check valve has been opened.
