Abstract

The equipment for measuring the speed of rotation of a vehicle wheel (14) carried by a wheel axle (12) comprises a tachometer (30) having a stator (32) suitable for being secured to the wheel axle (12), a rotor (34) suitable for being rotated by the wheel (14), and a connector (110) secured to the stator (32) for electrical connection of the tachometer. The connector (110) includes a set of connection terminals (114A). The equipment further comprises an information transmission member (82) carried by the tachometer stator (32) and suitable for co-operating with a complementary information transmission member (74) constrained to rotate with the wheel (14). Said tachometer connector (110) includes additional connection terminals (114B) to which said information transmission member (82) is connected for transmitting said information.

Claims

1-6. -6. (cancelled).

7. Equipment for measuring the speed of rotation of a vehicle wheel (14) carried by a wheel axle (12), the equipment comprising a tachometer (30) having a stator (32) suitable for being secured to the wheel axle (12), a rotor (34) suitable for being rotated by the wheel (14), and a connector (110) secured to the stator (32) for electrical connection of the tachometer, which connector (110) includes a set of connection terminals (114A), the equipment further comprising an information transmission member (82) carried by the stator (32) of the tachometer and suitable for co-operating with a complementary information transmission member (74) constrained to rotate with the wheel (14), wherein said tachometer connector (110) includes additional connection terminals (114B) to which said information transmission member (82) is connected to transmit said information.

8. Measuring equipment according to claim 7, wherein the information transmission member (82) is secured to the tachometer (30) to form a unitary module, and wherein the equipment includes means (84, 105) for fixing the unitary module to the wheel axle (12).

9. Measuring equipment according to claim 8, wherein said means for fixing the unitary module to the wheel axle comprise a bell (84) adapted to be engaged in the wheel axle (12), and wherein the tachometer (30) and the information transmission member (82) are connected to said bell.

10. Equipment according to claim 7, wherein the tachometer stator includes at least one duct (124) for passing conductors (122) to provide the connection between the information transmission member (82) and the connection terminals (114B) of the connector (110).

11. Equipment according to claim 7, the equipment having fitted thereto a shielded tube (128) providing mechanical and electromechanical protection to conductors (122) providing the connection between the information transmission member (82) and the connection terminals (114B) of the connector, which tube extends generally along the stator (32).

12. A wheel assembly comprising a vehicle wheel (14), a wheel axle (12) carrying the wheel (14), and equipment for measuring the speed of rotation of the wheel according to claim 7.
