Relative rotation state detecting device

Abstract

PROBLEM TO BE SOLVED: To provide a relatively rotated condition detecting device for preventing an increase in the number of components when setting a relative position relationship between two detection parts in the direction of a rotational axis to be a predetermined relationship.SOLUTION: The relatively rotated condition detecting devices 74, 83 have detection parts 75, 76, 84, 85 provided on members 4C, 61, 17, 24, respectively, to be relatively rotated with the rotational axis A1 as a base for detecting the condition of relative rotation between each of the members 4C, 61 and each of the members 17, 24. When the members 4C, 61 and the members 17, 24 are relatively moved in a preset range to the direction of the rotational axis, the size of at least one detection part in the direction of the rotational axis is set so that the relative position relationship between each of the detection parts 75, 84 and each of the detection parts 74, 85 in the direction of the rotational axis is set to be the predetermined relationship.

Description

technical field [0001] The present invention relates to a relative rotation state detecting device for detecting the relative rotation state of two parts. Background technique [0002] Generally, the torque of the driving force source of the vehicle is transmitted to the vehicle through a power transmission path. Various rotating parts are arranged on the power transmission path, and the rotating state of the rotating parts, such as the rotation angle and the number of revolutions, is detected. JP-A-10-89446 (paragraphs 0030 to 0035, FIG. 5 ) describes an example of a device capable of detecting the rotational state of a rotating member provided on a power transmission path. [0003] This publication describes a hydraulic pressure generator and a power output device. The power output device has an engine, a first electric motor, a second electric motor, and a planetary gear. The first electric motor, the second electric motor, the planetary gear, and the like are arranged i...

[0006] However, in the power output device described in the above publication, in the case where the ring gear shaft and the sun gear shaft are provided inside the case, according to the relative positions of the case, the ring gear shaft, and the sun gear shaft in the direction of the rotation axis, it is analyzed in the direction of the rotation axis. The overlapping amount of the stator and rotor of the machine may be less than the specified amount

In order to avoid this situation, positioning parts (for example, thin shims) are used to adjust the relative positions of the case, the ring gear shaft, and the sun gear shaft in the direction of the rotation axis, but setting the positioning parts will bring about a problem of increasing the number of parts
