本発明は、車両の傾斜度測定装置に関し、より
詳細には、自動車の個々の車輪のトー測定に好適
な車輪の傾斜度測定装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicle inclination measurement device, and more particularly to a wheel inclination measurement device suitable for measuring the toe of each individual wheel of an automobile.

と称す。 Toe, camber, caster, and kingpin angles are set for automobile wheels, especially front wheels, to improve steering stability. It is necessary to appropriately set these various factors to stabilize the driving performance of the vehicle itself. Among these, the correct setting of toe is particularly important as it is directly related to matching the direction of the steering wheel with the direction of travel of the vehicle. Here, the toe of the automobile refers to the inclination θ of the wheels 2 with respect to the traveling direction D of the vehicle 1 when the automobile is viewed from above in FIG. When it slopes inward, it is called toe-in, and when it slopes outward, it is called toe-out.

せることが難しくその為の整合装置やズレを補正
する補正装置の設備費が高くなる。 In order to align the orientation of the steering wheel with respect to the direction of travel of the vehicle, it is necessary to measure the inclination, or toe, of each wheel relative to the direction of the vehicle and correct it individually so that the left and right sides are equal. Additionally, in recent years, there has been an increase in the number of automobiles with independent suspension on all four wheels, particularly in order to reduce unsprung weight and improve ride comfort.
It is necessary to measure and manage not only the front wheels but also the individual toe values of the rear wheels. In this case, it is difficult to align the front-rear direction of the vehicle with the measurement reference line of the wheel inclination measurement device, and the equipment costs for the alignment device and correction device for correcting the deviation are high.
本発明は以上の点に鑑みてなされたものであつ

They are rotatably connected via f and 10f.
By providing the connecting rod 14 in this manner, the longitudinal axis of the connecting rod 4 can always be automatically aligned with the vehicle center line in the longitudinal direction of the vehicle to be measured. Then, each vertical rod 8 and the connecting rod 14
are always kept parallel by the above-mentioned connecting mechanism, so even when the connecting rods 14 are inclined with respect to the front-rear direction, as shown in FIGS. 5 and 6, the direction of each vertical rod 8 remains the same. It is always parallel to the vehicle center direction of the vehicle where toe measurement is to be performed. still,
In this specification, the vehicle centerline of the automobile to be measured is defined as a straight line formed by connecting the tread center between the front wheels and the tread center between the rear wheels.

7 and 17 are placed close to each other to securely sandwich each wheel 2 from both sides. At this time, the turntable 15 rotates around the shaft 7 according to the degree of inclination of each wheel 2 with respect to the vehicle center direction, that is, the toe. in this case,
In Fig. 4, the wheel 2 is located at its widthwise center line C 1
is normally placed on the measuring table 19 with some deviation from the center plane C2 in the width direction of the turntable 15, but due to the free sliding effect of the conveyor plate 4 along the rail 3, the detection As the clamping operation of the tool 17 is carried out, the width direction center line C 2 of the turntable 15 can be easily aligned with the width direction center line C 1 of the wheel 2 automatically without requiring much force. . Therefore, if the direction pointed by the pointer 20 attached to each turntable 15 matches the direction in which the widthwise center line C1 of the wheel 2 is located, and the value indicated by the pointer 20 is read from each corresponding scale plate 9, This represents the toe value of each wheel 2. That is, since the zero point of each scale plate 9 always indicates the direction of the vehicle center line as described above, there is no need for correction according to the degree of inclination of the vehicle to be measured with respect to the measuring device I, and the pointer 20
directly indicates the true toe value of each wheel. In this way, if the operator corrects the toe of each wheel so that the toe values of the front, rear left, and right wheels are equal to the predetermined value while watching each pointer 20, the direction of movement of the automobile and the steering wheel can be adjusted. Orientation is aligned.
