Problems solved by technology

Thus, for example in FIG. 20B , if the inclination of the wheel 200 is measured statically when the wheel 200 is tilted by an angle (θ+α) with respect to the direction of travel of the vehicle, then an error in the angle α will be generated.

Embodiment Construction

[0040] Various embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0041] figure 1 A wheel alignment measuring device according to a first embodiment of the present invention installed on a vehicle production line is shown.

[0042] The vehicle 10 has a body 11 , a subframe 12 attached to the bottom of this body 11 and extending in the width direction of the vehicle, and a pair of suspension assemblies 13 , 14 attached to the body 11 and the subframe 12 . The vehicle 10 is suspended from a hanger 17 which is movably attached to a transfer hanger rail 16 of the production line. Reference numerals 17 a , 17 a denote hanger ends, and 17 b , 17 b denote support plates attached to the hanger ends 17 a , 17 a so as to support the bottom of the vehicle body 11 .

[0043]The suspension assembly 13 includes a plurality of suspension arms 21, 22, 23 and 24, which extend outward from the subframe 12 and are movable up and ...

Abstract

A method and apparatus for measuring the wheel alignment of a vehicle on a production line. In the measuring method, a wheel hub (55) having a plurality of hub bolts (56) for mounting a wheel to is rotated while displacements of the hub bolts are measured with displacement measuring sensors (73, 74). The wheel alignment is measured by calculating an angle of inclination (theta) of the wheel hub on the basis of the measured displacements of the hub bolts.

Description

technical field [0001] The invention relates to a method and a device for measuring the wheel alignment of vehicles on a production line. Background technique [0002] Wheel alignment in a vehicle, expressed for example as toe-in and camber, is an important factor affecting the straight-line stability, cornering behavior and steering behavior of the vehicle. The toe-in aspect of wheel alignment will now be explained with reference to Figures 20A to 20C herein. [0003] Toe-in refers to the inclination, or degree of inclination, of the front portion of the wheel 200 as shown in FIG. 20B from the state shown in FIG. 20A , with the wheel 200 pointing in the forward direction of the vehicle. This toe is generally obtained by statically measuring the inclination angle θ of the wheel 200 (this inclination angle is called a toe angle). An apparatus using this measuring method is disclosed, for example, in Japanese Patent Laid-Open No. HEI-3-26767, entitled "Vehicle WheelInclinati...
