    [0001] The present invention relates to a device for measuring the axial and radial distance between the outer surface and the outer surface of a wheel and an electrode of the outer surface of the outer surface of a wheel. of a wheel and a wing of a motor vehicle. It also relates to a method of implementing the device. This type of measuring device exists and has already been patented.
    [0002] For example, reference can be made to patent application FR2967251, which relates to a device for measuring the axial and radial distance between the outer surface of a wheel and a wing of a motor vehicle, and whose particularity is that it comprises positioning elements for placing said device on the wheel, a variable position slider support, an axial slider and a radial slider. However, such a device has the disadvantage of being mounted on the wheel completely manually, requiring long and complex adjustments by means of specific tools, which may cause some inaccuracies in the measurements. A measuring device according to the invention can be mounted on a vehicle wheel in a simple, fast and precise manner, in particular by avoiding the disadvantages noted in the state of the art. The invention relates to a device for measuring the axial and radial distance between the outer surface of a wheel and a wing of a motor vehicle, said device comprising a measuring support and means for mounting said device on the wheel, said support having a variable position and being provided with a radial slider adapted to measure said radial distance and an axial slider adapted to measure said axial distance. The main characteristic of a measuring device according to the invention is that the mounting means comprise a control member, a deployment mechanism and at least three positioning arms adapted to be placed against the wheel, the actuation of the control member triggering said mechanism for deploying said arms in a position adapted to the dimensions of the wheel, to be able to fix said device on said wheel. In this way, a measuring device according to the invention has a semi-automatic appearance, since the deployment of the positioning arms on the wheel is achieved by means of a simple actuation of a control member, requiring neither intervention manually on said arms or an adjustment thereof. Said device is thus fixed systematically on the wheel, in a precise and rigorous manner, coaxially with the axis of the wheel, to allow usable measurements of the axial and radial distance between the outer surface of the wheel and the wing of the corresponding vehicle.
    [0003] This device also makes it possible to measure the diameter and the width of the wheel. In order to ensure a solid and homogeneous mounting of the measuring device on the wheel, it is assumed that the three arms are homogeneously distributed around this wheel, two successive arms preferentially forming an angle of 120 ° between them. Advantageously, the deployment mechanism is fixed to a platform and comprises a rotary cam in contact with at least one rotating link associated with each arm, the actuation of the control member causing a rotation of the cam, then a rotation of each rod to deploy each arm by contact. The platform serves as a base able to bear against the wheel and supporting the main fixing elements of the measuring device according to the invention. Since the device comprises at least three arms, it also comprises at least three rotating rods. In other words, each arm is associated with a connecting rod. The cam is rotated by means of the control member, said cam causing the rotation of each connecting rod by contact. Preferably, each arm is slidably mounted in a slideway secured to the platform, the rotation of each rod caused by the rotation of the cam, causing a sliding of each arm in said slide. The deployment of the arms can be either continuous or discrete in successive increments.
    [0004] Preferably, the cam comprises at least one lobe which is in contact with an arm, said lobe remaining in contact with the arm during the entire deployment phase of said arm. In this way, the cam comprises as many lobes as there are deployment arms, each lobe being dedicated to the specific deployment of an arm. Advantageously, the control member is a rotary handle, which is connected to the cam by means of a relay axis, a rotation of said handle causing a simultaneous rotation of said cam. In this way, the deployment mechanism of the arms is mechanical, insofar as it implements a series of solid parts interacting with each other by mechanical contact. With such a rotary handle, the displacement amplitude in translation of each positioning arm is proportional to the angular amplitude of rotation of said handle. Advantageously, each arm is rectilinear and ends with a radial support member and adapted to grip the wheel, each of said arms comprising a locking means adapted to exert pressure on each of said support elements to hold against said wheel . Preferably, this locking means comprises at least one lateral spring collar. Advantageously, this locking device is triggered manually by an operator, when each positioning arm has deployed beyond the diameter of the wheel, to bring each radial support member against said wheel. Preferably, each arm comprises at least one axial support element.
    [0005] Preferably, the measurement support is an arm pivotally mounted on the platform, said arm being telescopic. The fact that the arm is telescopic widens the spectrum of use of a measuring device according to the invention, in particular to make measurements on small vehicles.
    [0006] Advantageously, the platform comprises a locating element for pre-positioning said platform correctly against the wheel. Preferably, this marker element is a spirit level, said platform to be in front of the wheel so that the spirit level is perfectly horizontal. The subject of the invention is a method for implementing a measuring device according to the invention. The main characteristic of a method according to the invention is that it comprises the following steps: - approaching the device on the wheel by means of the locating element, - actuating the control member to deploy the positioning arms, - trigger the locking means to fix the device on the wheel, - put one end of the slider support in contact with the wing, - put the radial slider in contact with the outer surface of the wheel, contact the axial slider with the wing, - determine the axial and / or radial distance using the axial and / or radial slider. The following is a detailed description of a preferred embodiment of a measuring device according to the invention, with reference to FIGS. 1 to 5. FIG. 1 is a perspective view of a measuring device According to the invention mounted on a vehicle wheel, FIG. 2 is a front view of a measuring device according to the invention mounted on a wheel, and of a vehicle wing. FIG. 3 is a partial view of FIG. FIG. 4A is a rear view of the measuring device according to the invention in a retracted position, FIG. 4B is a rear view of the device of FIG. FIG. 4 is a front view of a measuring device according to the invention showing a support of sliders in three different positions.
    [0007] In order to better understand the orientation of the different parts, the detailed description is made with respect to a frame linked to the vehicle, and in which the X axis is a longitudinal axis of the vehicle, the Y axis is a transverse axis of the vehicle and the Z axis is a vertical axis. Referring to Figures 1, 2 and 3, a measuring device 1 according to the invention is adapted to be fixed on a wheel 2 of a vehicle, which is mounted on said vehicle. This device 1 makes it possible to evaluate the mounting quality of said wheel 2 on the vehicle by measuring, on the one hand, the radial distance along a vertical axis Z and separating the tread 4 from the wheel 2 and an edge 5 curved a wing 6 surrounding said wheel 2, and secondly, the axial distance in a transverse direction Y of the vehicle, and separating an outer sidewall region 7 of the wheel 2 and said curved edge 5. Referring to FIGS. 1, 2, 4A and 4B, the measuring device 1 comprises a platform 8, three positioning arms 9, a mechanism for deploying said arms 9 and a support 10 for sliders 11, 12.
    [0008] The platform 8 is a thin flat part comprising a circular body 13 extended by three protuberances 14 extending in the same plane as that of said body 13, two successive protuberances 14 forming an angle of 120 ° between them. These protuberances 14 are rectilinear and are configured to serve as slide rails to the three positioning arms 9.
    [0009] As shown in FIG. 5, the slider support 11, 12 comprises a telescopic arm 15 which is rotatably mounted on the platform 8 about an axis of rotation, which is perpendicular to the plane of said platform 8 and passes by the center of the circular body 13 of this platform 8. This telescopic arm 15 is made in two parts 40,41, one 41 of said parts being able to slide in the other part 40 and to be fixed in the desired position at by means of a clamping screw 42. As shown in FIG. 1, the telescopic arm 15 comprises a radial slider 11 adapted to bear on the tread 4 of the wheel 2, and an axial slider 12 capable of coming into resting against the curved edge 5 of the wing 6. The radial slider 11 is associated with a bracket 110 and a clamping screw 112 allowing it to slide along the telescopic arm 15. Furthermore, the axial slider 12 is mounted on slides so that it can be moved along the axis Y, and comprises a stop 120 intended to be placed in abutment against the outer face of the wing 6. These two sliders 11 and 12 respectively make it possible to measure the indicated radial distance Z 'in FIG. the axial distance indicated Y 'in FIG. 3. The platform 8 supports a spirit level 16, which is a locating element making it possible to pre-position said platform correctly on the wheel 2, before fixing the measuring device 1 on said wheel 2. Referring to FIGS. 4A and 4B, a deployment mechanism of the positioning arms 9 comprises a control handle 17, a cam 18, and three connecting rods 19. The cam 18 is a flat piece having three elongate lobes 20, making an angle of 120 ° between them. This cam 18 is rotatably mounted on the platform 8, about an axis of rotation perpendicular to the plane of said platform 8, and passing through the center of the circular body 13 of this platform 8. Each lobe 20 is comparable to a straight strip ending with a rounded end. Each connecting rod 19 is embodied by an elongated bar, rotatably mounted on the platform 8 about an axis of rotation which is parallel to the axis of rotation of the cam 18. Each link 19 has its own axis of rotation 190, which is distinct from that of other rods 19 and that of the rotating cam 18. Referring to Figures 1, 2, 4A, 4B and 5, each positioning arm 9 is an elongate member having a longitudinal and central slot 21. This slot 21 is made inside the arm 9 and therefore has a closed contour. Each arm 21 is placed in a radial protuberance 14 of the platform 8 serving as a slide, and is slidable in each of these protuberances 14 under the effect of the thrust of a rod 19. Each arm 9 thus has a first end which is inserted in the slideway 14, and a second end which is free. At this second end, each arm 9 has a radial support rod 22 whose longitudinal axis is perpendicular to the longitudinal axis of said arm 9. Inside the slot 21 of each arm 9 is inserted a axial bearing pad 23, which is embodied by a cylindrical disc. Each shoe 23 is mounted in the slot 21 by means of a cantilever axis passing through said slot 21, one end of the shaft ending in said shoe 23 and the other end by a clamping nut 24 manually actuated. The position of the shoe 23 is adjustable in translation along each arm 9 to allow the application of the pads 23 on the sidewall of the tire. Indeed, depending on the characteristics of the tire, the sidewall area of the tire may be more or less close to the periphery, as is the case for example on low-profile tires. Referring to Figures 1, 2 and 5, each arm 9 is connected to the center of the platform 8 by means of a prestressed spring 25.
    [0010] Referring to Figures 1, 2 and 5, the control handle 17 is rotatably mounted on the platform 8 about an axis of rotation which is perpendicular to the plane of the platform 8 and which passes through the center of the circular body 13 of said platform 8. This rotary handle 17 is connected to the cam 18 via a relay axis, passing through the platform 8, and joining said handle 17 in the center of said cam 18. This relay shaft is shaped to transmit directly the rotational movement of the control handle 17 to the cam 18. In other words, the rotation of the control handle 17 simultaneously generates the rotation of the cam 18 with the same angular velocity. The control handle 17, the spirit level 16 and the telescopic arm 15 serving to support the sliders 11, 12 are fixed on one side of the platform 8, while the cam 18, the rods 19 and the positioning arms 9 are fixed on the other side of said platform 8. A method of implementing a measuring device 1 according to the invention, follows the following steps: a step of approaching the device 1 on the wheel with the level to bubble 16 which must be positioned horizontally, a step of manual rotation of the control handle 17 by an operator, a step of simultaneous deployment and automatic positioning arms 9, through the rotation of the cam 18 driving contact the rotation of each rod 19. The rods 19 are positioned on the platform 8, so that their rotation causes contact by the translation of each arm 9 in the associated slide 14. a step of stopping said deployment, when the radial support rod 22 of each arm 9 exceeds the diameter of the wheel 2, a step of adjusting the shoe 23 of each arm 9 at the sidewall region 7 of the wheel 2, by sliding the shoe 23 in the slot 21 and tightening by the nut 24, a step of applying the measuring device, via the pads 23 against the sidewall of the tire, immediately followed by an actuation of a means of locking involving a spring-loaded collar, to release each of said arms 9, so that it retracts under the effect of the prestressed spring 25 which attaches it to the center of the platform 8. Each rod 22 of radial support then comes into contact of the tread 4 of the wheel 2 and is held in this position by means of this spring 25, a step of contacting an end of the telescopic arm 15 with the wing 6, a step of setting contact of the radial slider 11 with the tread 4 of the a wheel 2, a step of contacting the axial slider 12 with the curved edge 5 of the wing 6, a step of determining the axial and / or radial distance with the aid of the axial slider 12 and / or radial 11 According to a simplified variant of a measuring device according to the invention, the springs 25 are eliminated and the associated step of retracting the arms 9 to bear the rods 22 on the tread, is obtained by a reverse movement of the control handle 17, which can be blocked by a rack system or the like. Referring to Figure 5, the wheel cover 2 commonly called wheel black is a regulatory measure. It designates the radial distance Z 'between the wheel 2 and the wing 6 for angles of 30 ° and 50 ° towards the front and towards the rear of the vehicle relative to a vertical axis Z of the wheel 2. The device 1 according to the invention allows the indexed inclination of the telescopic arm 15 supporting the sliders 11, 12, for the four positions necessary for the regulatory verification of the wheel cover 2. To carry out the measurements, it is pivoted said telescopic arm 15 to the desired angle and it is put the cursor 12 in contact, below, with the wing 6, by adjusting the telescopic arm 41 associated with the clamping knob 42. The slider 11 is then brought into contact with the strip of tire rolling. FIG. 5 illustrates three positions of the telescopic arm 15, at -30 ° with respect to the vertical position, at + 50 ° with respect to said vertical position and at the vertical position. Markings on the body 13 can facilitate the positioning of the arm 15. The reading of the wheel black value can be performed by a scale carried by the telescopic arm, or by means of a digital display.
    [0011] The check of the wheel cover 2 is carried out in the same way as the measurement of the radial distance for the wheel black 2. The end of the telescopic arm 15 is moved until it comes into contact with the edge 5 of the wheel. wing 6, then the radial slider 11 is moved until it comes into contact with the outer surface of the wheel 2. Finally, the axial slider 12 is moved in the slideways in the Y direction, until the stop 120 is contacted with the wing 6. A graduation, carried by the slider 12 then reads the value of the recovery, the plane formed by the position of the pads 23, forming the reference plane. To be approved, the measured recovery value must be positive. According to another embodiment, a digital display can be used.
