STRUCTURE FOR FITTING ROTARY DISPLACEMENT SENSOR

摘要

A structure for fitting a rotary displacement sensor for detecting the rota ry displacement of rotary shafts, such as kingpins provided in vehicles, aiming at preventing the degradation of the durability and damage due to the force exerted on the input shaft of the rotary displacement sensor in the radial direction and achieving a high level of measurement precision by eliminating the play with the rotary shaft. 'The rotary displacement sensor is fixed to a member supporting the rotary shaft rotatably, in such a way that the central axis of the input shaft is substantially aligned with t he central axis of the rotary shaft. The input shaft and the rotary shaft are linked by rotatio n transmitting means. The rotation transmitting means permits by elastic deformation misalignment of the central axis of the input shaft with the central axis of the rotary shaf t and regulates the relative rotation of the input shaft to the rotary shaft. Even if any misalignment occurs between the central axis of the input shaft and the central axis of the rota ry shaft, the force exerted from the rotary shaft on the input shaft in the radial directi on is absorbed and relaxed, and the rotation of the rotary shaft is transmitted as it is to the input shaft.
