Embodiment Construction

[0041] Hereinafter, embodiments of the present invention will be described in detail by way of examples. However, the components described in this embodiment are examples only, and the technical scope of the present invention is determined by the claims, and is not limited to the following individual embodiments.

[0042]

[0043] First, refer to figure 1 with figure 2 The configuration of the continuously variable transmission of this embodiment will be described. The continuously variable transmission 1 of the present embodiment is a transmission that can make the speed ratio i (i=rotation speed of the input shaft / rotation speed of the output shaft) infinite (∞) to make the rotation speed of the output shaft "0", that is, a so-called IVT. A type of (Infinity Variable Transmission).

[0044] The continuously variable transmission 1 of the present embodiment includes an input shaft 2 , an output shaft 23 , and six eccentricity adjustment mechanisms 4 .

[0045] The inp...

Abstract

The invention provides a continuously variable transmission. The continuously variable transmission comprises a plurality of distance detection parts (50) fixed on a transmission shell (30) and used for detecting the distance to detected parts, and an output shaft torque calculation control part (52) which calculates the torque of an output shaft (23) based on detection values of the distance detection parts (50). The output shaft torque calculation control part (52) comprises an average value calculation part (56) calculating the average value of the detection values of the distance detection parts (50), and an output shaft torque calculation part (57) calculating the torque of the output shaft according to the average value. The distance detection parts (50) at least include a first sensor and a second sensor. The gaps in the circumferential direction of the detected parts of which distances are detected by the first sensor and the second sensor is the interval of a plurality of rollers*1 / 2 and the interval of the rollers *M (M is an integer).

Description

technical field [0001] The present invention relates to continuously variable transmissions. Background technique [0002] For example, Japanese Patent Laid-Open No. 2012-251608 describes a control device for a four-joint linkage type continuously variable transmission that converts rotation of an input shaft connected to an engine into reciprocation of a connecting rod. Movement, and use the one-way clutch to convert the reciprocating motion of the connecting rod into the rotary motion of the output shaft. [0003] In the control device of Japanese Patent Application Laid-Open No. 2012-251608, it is disclosed that the cumulative number of rotations of the input unit and the cumulative number of rotations of the pinion shaft are counted, and the difference between them is used to estimate the rotation radius adjustment. The radius of rotation of the mechanism, based on which the torque transmitted to the input shaft or output shaft is estimated. [0004] In the case of the...
