1. a kind of device for measuring wheel alignment parameter in vehicular chassis system KC testing stands, for wheel alignment parameterIt is accurately measured, which is characterized in that the device includes:

  • Support frame device on the Vertical loading platform of KC testing stands is set, connect with the support frame device extreme ends six fromBy degree parallel institution platform and the turntable for being connect with wheel in six-degree-of-freedom parallel connection mechanism platform end is set, it is to be measuredThe wheel of amount is arranged on the rotation loading bench of KC testing stands and is fixedly connected with turntable, and makes plane of rotor disc and wheel tyreNeutral surface is parallel and coaxial, and one end of the turntable and six-degree-of-freedom parallel connection mechanism platform is fixed, and the six-degree-of-freedom parallel connection mechanism is flatThe other end of platform is fixedly connected with support frame device;

    Wherein, six branches are provided on the six-degree-of-freedom parallel connection mechanism platform, each branch is with the soft of multiple degree of freedomProperty branch, displacement sensor is housed, to measure the change in displacement of each branch and in this, as the position of wheel to be measured on each branchVariation is moved, to calculate the spatial attitude of wheel, in conjunction with the displacement sensor value of KC testing stand loading systemsObtain tire positional parameter;

    The six-degree-of-freedom parallel connection mechanism platform includes the platform of two parallel intervals arrangement, respectively moving platform (10) and fixed platform(11), turntable (9) is fixedly connected with moving platform (10), and fixed platform (11) is fixedly connected with support frame device extreme ends;

    It is describedThe moving platform (10) of six-degree-of-freedom parallel connection mechanism platform is fixed by magnet and turntable (9), and six branches setting is dynamic flatBetween platform (10) and fixed platform (11) and end is connect with the two by hook hinge respectively;

    Each branch in six movement branched chains is made of two section connecting rods, and two section connecting rods are mutually socketed in connecting pin, and canIt is mutually shifted in the axial direction, location hole is both provided on two section connecting rods of each branch, for being saved two by positioning pin (21)Connecting rod locks, and realizes in original design position and off working state to the support of moving platform;

    In original design position, with calmlyPosition pin locks two section connecting rods, and when testing stand measures, which is unclamped;

    Support frame as described above device includes supporting rack pedestal (16) and the vertical rack and horizontal stand for being mutually perpendicular to arrangement, branchSupport device is in totally " perpendicular type ", and vertical rack is fixed on support frame as described above pedestal (16), horizontal stand one end endPortion is fixed with one with vertical rack, and other end end is fixedly connected with fixed platform (11), and support frame as described above pedestal (16) passes throughGuide rail is connect with Vertical loading platform (2), and supporting rack pedestal (16) can realize that position in the longitudinal direction is adjusted by guide rail;

    The vertical rack includes the vertical support arm (15) being vertically arranged and coaxial package in it and can be mutually shifted perpendicularStraight inner support (14) so that vertical rack has the function of the length adjustment on vertical direction, vertical support arm (15) fixed settingOn supporting rack pedestal (16), it is provided in the corresponding side surface of vertical support arm (15) and vertical inner support (14) and is axially arrangedSliding slot (26), the Relative sliding between vertical support arm (15) and vertical inner support (14) are fixed on by bolt (13) afterwards in placeTo which the two is relatively fixed locking on sliding slot (26);

    The horizontal stand includes horizontally disposed horizontal support arm (12) and coaxial package in it and can be in the horizontal directionThe horizontal inner support (14) of relative movement so that horizontal stand has the function of the length adjustment on vertical direction, horizontal support arm(12) end is fixedly connected with fixed platform (11), and horizontal support arm (12) is provided with in the corresponding side surface of horizontal inner support (14)The sliding slot (27) being axially arranged, the Relative sliding between horizontal support arm (12) and horizontal inner support (14) pass through bolt afterwards in place(13) it is fixed on sliding slot (27) the two being relatively fixed locking;

    The horizontal inner support (14) is structure as a whole with vertical inner support (14), i.e. the rack body with right angle bending.
