摘要:
A hub-bearing assembly for the wheel of a motor vehicle includes a rotatable hub (18) having a radial flange (17) with bores (16) formed therethrough. Wheel fastening studs (10) each have a stem (12) inserted non-forcedly through a respective bore (16). The studs (10) are fixed to the flange (17) by an adhesive or cementing material.
摘要:
Sealing device (1) for rolling contact bearings provided with a shield (2) which may be installed onto an outer race (11) of the bearing (12), and presenting a lateral cylindrical wall (21) which is suitable for being arranged in a radially intermediate position between an encoder (16) and a reading sensor (17) of the bearing (12), and a passing window (29) which is obtained through the lateral cylindrical wall (21) in order to permit the sensor (17) to face the encoder (16); a cover (40) made of plastic material being arranged in such a way as to close the window (29), and being selectively mobile in order to effect variations in pressure between the inside and outside of the bearing (12) between two extreme operating positions in at least one of which the cover (40) is suitable for substantially sealing the window (29).
摘要:
Encoder for rolling contact bearings provided with a support portion which is interference-mounted onto a rotating race of the rolling contact bearing, and with a control portion which is integral with the support portion in order to emit a signal in relation to the angular speed of the rotating race; the support portion presenting a rigidity which is less than that of the control portion in order to absorb any eventual deformation which might be due to assembly or functioning.
摘要:
Sealing device (1) for a rolling bearing (2) which is provided with an inner race (5), which is axially blocked by a blocking element (4) which is suitable for being arranged in direct contact with a feedback element (6); the sealing device presents a support element (9) which is mounted on the inner race (5), an encoder wheel (8) which is installed on the inner race (5) and which is an integral part of the support element (9) itself, and a static sealing element (10), which is also an integral part of the support element (9) and which, in turn, presents two lips (21, 22) which are substantially parallel in relation to each other and which extend opposite the support element (9), a first lip (21) of the two lips (21, 22) extends towards the feedback element (6) and comes into contact with it, and a second lip (22) of the two lips (21, 22) extends towards a frontal surface of the inner race (5) and comes into contact with it.
摘要:
Bearing wheel hub unit (1) is provided with a mounting flange (3) which is integral with an inner race (21) of the bearing (2) in order to mount a wheel, and with a centering collar (4) which extends from a frontal surface (31) of the flange (3) to permit the centering of the wheel in relation to the unit (1). The centering collar (4) produced, preferably of alloy, in such a way as to be independent of the mounting flange (3), and is assembled with the flange (3) by fixing onto the frontal surface (31).
摘要:
A hub-bearing unit (10) has a rotatable outer race (30) fixable to a wheel and an inner stationary hub (20) forming a passage (27) for pressurized air coming from a source of pressurized air mounted onboard of a vehicle. Tightly fitted on the axially outer side of the unit (10) is a cylindrical cover (50) defining with the unit (10) an airtight chamber (51) communicating with the passage (27). The cover (50) has a through bore (55) for establishing air communication between the chamber (51) and a tube (A, B) for conveying pressurized air to the tire. The cover has an outer wall (52) with a cylindrical portion (52b) axially protruding beyond the hub-bearing unit (10) so as to provide a cylindrical surface for centering the wheel of the vehicle.
