Problems solved by technology

Therefore, in this continuously variable transmission, the pressing force toward the input disc side does not act on the output disc, and the clamping force of the friction rollers decreases, and there is a possibility that the transmission torque capacity between the input disc and the output disc cannot be ensured.

Embodiment

[0022] based on Figure 1 to Figure 7 Embodiments of the continuously variable transmission according to the present invention will be described.

[0023] The continuously variable transmission of this embodiment is configured as a so-called traction planetary gear mechanism composed of a plurality of rotating elements, and includes an input member, an output member, and a rotating member sandwiched between the input member and the output member. The frictional force generated by pressing the member against the rotating member transmits torque between the input member and the output member, and continuously changes the transmission ratio between the input member and the output member. In such a continuously variable transmission, the input member and the output member are pressed against the rotating member to generate frictional force between them, and torque transmission between the input member and the output member is enabled by the frictional force. If described based on...

Abstract

A continuously variable transmission having a continuously variable transmission mechanism for transmitting torque between an input side and an output side by means of frictional forces generated by pushing the input disc and the output disc against the planetary balls and continuously varying a transmission gear ratio between the input side and the output side includes a second group of helical gears capable of generating a first axial force for pushing the input disc toward the output disc, a first group of helical gears capable of generating a second axial force for pushing the output disc toward the input disc, and a thrust bearing and a central shaft for transmitting, when an opposite force in such a direction as to move the input disc away from the output disc and opposite force to the first force is generated on a side of the input disc, the opposite force to the output disc.

Description

technical field [0001] The present invention relates to a continuously variable transmission having a continuously variable transmission mechanism that includes an input member, an output member, and a rotating member sandwiched between the input member and the output member, and is formed by pressing the input member and the output member against the rotating member. The generated frictional force transmits torque between the input member and the output member, and continuously changes the transmission ratio between the input member and the output member. Background technique [0002] Conventionally, such a continuously variable transmission has been known to include an input disc as an input member, an output disc as an output member, and a friction roller as a rotating member, and the transmission ratio is changed by changing the tilt angle of the friction roller. The so-called toroidal continuously variable transmission. For example, Patent Document 1 below discloses a ...
