JPS6472029A - Camber angle detecting device - Google Patents

Abstract

PURPOSE:To measure the angle with high accuracy by moving the upper contacter installed in an arm, so as to bring into contact with one upper side face of a wheel, and detecting an angle displacement from a prescribed reference line of the arm at that time. CONSTITUTION:On the upper surface of a horizontal bracket 17c of an outside roll assembling body 17 of an inspection device, a pair of side walls 35 are provided vertically at the interval of a prescribed distance, and between them, a sensor shaft 36 is provided so as to be freely rotatable. In the center part of the shaft 36, a sensor arm 38 is fixed integrally in a state of extending in the roughly vertical upper direction, and in its tip part, a camber angle detecting roll 20c is held 38a. Between the side walls 35, moreover, a shaft 40 extends and an angle detector (rotary encoder) 42 is fixed through a bracket 41. On the other hand, to the shaft 36, a bracket 43 is fixed, and it is in an engaged state to the detector 42 by the respective gears 43a, 42a. In this state, when the roller 20c is brought into contact with the outside face of the upper part of a tire W, the shaft 36 is brought to rotational displacement, its displacement quantity is detected by the detector 42 and a camber angle can be measured.
