    1527024 Tachogenerators KELSEYHAYES CO 8 March 1976 [16 July 1975] 09224/76 Heading GIN In a tachogenerator for a wheeled vehicle and of the type including a stator and rotor the rotor is provided with splines for providing a sliding drive connection from the associated wheel to the rotor. Tachogenerator housing 22 mounted in a cavity 12 formed at the outer end of a non-rotatable axle of a vehicle carries a toothed stator 26, a permanent magnet 31 and a coil 41. Toothed rotor 27 juxtaposed to stator 26 with an air-gap therebetween is pressed on to an enlarged diameter portion 28 of a drive sleeve or shaft 29 which is formed with female splines 48 mating with splines 48 of an input drive-shaft 49. The arrangement is such as to allow axial and some pivotal movement between the input drive 49 and drive sleeve 29 without exerting angular or axial forces on the rotor 27. Drive-shaft 49 is driven by the wheel to which it is connected via the hub-cap, Fig. 1 (not shown), and a resilient disc 52 having a circumferential groove 52 received within a diaphragm 53 fixed across the open end of the hub-cap. Disc 51 permits angular and radial movement to occur between the wheel, hub-cap and shaft 49. The whole arrangement is such that radial, angular and axial misalignments between the wheel and axle shaft 13 may occur without corresponding forces being exerted on the speed sensor.

    The invention relates to speed sensors mounted on wheels of vehicles equipped with anti-lock braking systems.
    The closest known technical solutions is a speed sensor for a non-driving wheel of a vehicle with an anti-lock brake system, comprising a stator, a rotor mounted to rotate relative to the stator, an electromagnetic means for receiving an electrical signal, and a shaft connecting the rotor with the wheel hub of the vehicle [1].
    In the known sensor, measurement distortions are possible due to deviations of the position of the wheel hub relative to the semiaxis from normal.
    The purpose of the invention is to improve the accuracy of measurements by reducing the influence of radial, angular and axial deviations of the position of the wheel hub relative to the axis from normal.
    This is achieved by the fact that the sensor is equipped with a sleeve installed in the housing and connected by a spline connection to the end of the shaft, the connection of the latter with the wheel hub is flexible and the rotor is mounted on the said sleeve. In addition, the flexible connection 'is made in the form of an elastic washer fixed in the wheel hub.
    FIG. 1 shows a wheel equipped with a CKopocTH f cut sensor, · in FIG. 2 - speed sensor.
    The speed sensor is located in the cavity 1 at the outer end of the axle shaft 2. The wheel hub 3 is mounted on the axle shaft 2 using bearings 4.
    A nut 6 is installed on the thread 5, pressing the gaskets 7 and 8 for axial adjustment of the bearings 4.
    The cap 9 is attached to the hub 3 with bolts and closes the end of the axle shaft 2.
    The sensor housing 10 forms an internal cavity 11 bounded by a cover 12 fixed in the flanged portion 13 of the housing 10. The toothed stator 14 is pressed into the housing 10 and abuts against the cover 12.
    A gear rotor 15 is located adjacent to the stator 14 and limits the air gap between them. The rotor 15 is pressed into part 16 of the larger diameter of the sleeve 17.
    A permanent magnet 18 is installed at the end wall of the housing 10. The mounting ring 19 wraps around and supports the magnet 18 and the adapter sleeve 20 installed by part 21 on part 22 of sleeve 17. The winding 23 wraps around part of sleeve 20 and has outputs 24 and 25 passing through axial drilling 26 in the semi-axis 2 to the anti-lock brake control system. The winding 23 is fixed from axial displacement by a centering washer 27.
    The sleeve 17 is connected by a spline connection 28 with a shaft 29, connected by means of an elastic washer 30 with a cap 9.
    When the hub 3 rotates, any deviation of its position relative to the axis 2 is compensated by a washer 30 (angular and radial deviations) and a connection 28 (axial and small angular deviations), thereby preventing disturbances in the operation of the electrical part of the sensor.

    A permanent magnet 18 is mounted on the end wall of the housing 10. The mounted ring 19 encloses and supports the magnet 18 and the adapter bushing 20 installed by part 21 on the part 22 of the bush 17. The winding 23 encloses a portion of the bush 20 and has outlets 24 25 extending through axial drilling 26 in axle 2 to anti-block braking control system. The winding 23 is secured against axial displacement by the centrifugal washer 27. The sleeve 17 is connected by a splined connection 28 to the shaft 29 connected by an elastic washer 30 to the cap 9. When the hub 3 rotates, any deviation from its position relative to the semi-axis 2 is compensated by the washer 30 (angular and radial deviations) and connection 28 (axial and small angular deviations), thereby preventing disruptions in the electrical part of the sensor. Claim 1. Speed sensor for a non-driving wheel of a vehicle with antiblocking a braking system comprising a stator housed in a semi-axle-mounted vehicle body, a rotor mounted with respect to the stator, electromagnetic means for receiving an electrical signal, and a shaft connecting the rotor with the wheel hub of the vehicle, increase the accuracy of measurements by reducing the effect of the radial, angular and axial deviations of the wheel hub position relative to the semi-axis from the normal one; it is equipped with a sleeve installed housing and associated ishitsevgm compound with said shaft end, wherein the bond from the last wheel hub is flexible, and the rotor is fixed on said sleeve.
