In this case, the sensor (gyroscope) will be installed at or below the center of the wheel, and the signal from the sensor (gyroscope) does not need to be corrected for errors related to roll.

[0003] like Figure 1 As shown in the figure, when viewed from the side of the car, the kingpin axis (or wheel steering axis) tilts backward or forward from the vertical direction at an angle called kingpin caster or caster. In the longitudinal vertical plane, the angle between the kingpin axis and the vertical line is called the kingpin caster angle.

[0004] According to the use specifications of the sensor (gyroscope) of the testing instrument, the sensor (gyroscope) should be installed in a horizontal position on the tested vehicle; then its output data is valid data; otherwise, it will cause errors in the output data;

[0005] The traditional sensor (gyroscope) will be installed on the shaft: the tension band is used to directly tie it to the shaft. This installation method makes it impossible to adjust the installation angle of the sensor (gyroscope). As a result, there will be a collection error in the output value of the sensor (gyroscope), affecting the final evaluation result. Furthermore, there may be a problem of the sensor (gyroscope) falling off due to loose bundling. This will cause certain safety risks in the test process. Utility Model Content

It is more convenient to arrange the extensions on the left and right sides above the installation and fixing box to connect with the bottom plate.

[0010] Further preferably, a baffle plate for preventing the sensor from falling is installed at the installation entrance of the installation fixing box by bolts, and the bottom of the installation fixing box is arranged with connecting bolts in a rectangular shape. By arranging the baffle plate at the installation entrance of the installation fixing box, the sensor is prevented from falling due to vibration of the tested vehicle, thereby affecting the experimental data of the tested vehicle.

[0011] More preferably, the number of the angle adjustment bolts and hinges is at least two. Providing at least two angle adjustment bolts and hinges prevents the position of the sensor from being non-horizontal due to errors in the parts, thereby affecting the actual measurement data of the measured vehicle.

[0012] The beneficial effects of the utility model are as follows: the sensor is arranged in an installation and fixing box, the installation and fixing box is connected to the bottom of the base plate by a connecting device, the base plate and the installation and fixing box are fixed below the front axle shaft of the automobile by a fixing piece arranged above the base plate, and the installation angle of the sensor is adjusted by an angle adjustment bolt and a hinge arranged between the base plate and the installation and fixing box to make it in a horizontal position, thereby reducing the error of the sensor's collected data and reducing the impact on the final evaluation result.
