- 一対のディスクにおける回転中心軸線方向で対向する面がトロイダル面に形成されかつ該一対のディスクにより形成されたキャビティを2つ有するとともに、それらのディスクに挟み付けられてそれらのディスクの間でトルクを伝達する2つのローラがそれぞれトラニオンによって回転自在に保持され、それらのトラニオンに設けられているトラニオン軸同士がリンク機構によって連結されているトロイダル式無段変速機において、
前記リンク機構は、前記各キャビティに設けられたローラを保持するトラニオン同士を、該キャビティから抜け出す方向の移動を阻止しかつトラニオン軸の軸線方向に相対的に移動するように連結する第1リンク部と、一方のキャビティに配置された第1ローラを保持する第1トラニオンおよび前記トラニオン軸の軸線方向において前記第1ローラと同一方向に移動する前記他方のキャビティに配置された第2ローラを保持する第2トラニオンを、前記トラニオン軸の軸線方向で同一方向に移動させるように連結する第2リンク部とを備え、
前記第2リンク部は、前記第1トラニオンと前記第2トラニオンとの前記トラニオン軸の軸線方向における相対位置のずれを許容するずれ吸収機構を有している
ことを特徴とするトロイダル式無段変速機。 - 前記ずれ吸収機構は、前記第2リンク部の少なくとも一部に設けられた弾性変形部によって構成されていることを特徴とする請求項1に記載のトロイダル式無段変速機。
- 前記ずれ吸収機構は、前記第1トラニオンと前記第2トラニオンとの少なくとも一方のトラニオンと前記第2リンク部との間に設けられた隙間によって構成されていることを特徴とする請求項1に記載のトロイダル式無段変速機。
- 前記第1リンク部は、該第1リンク部によって連結されたトラニオン同士が前記トラニオン軸の軸線方向で反対側に移動することができるように、前記トラニオン同士の間で揺動可能にかつ前記トラニオン軸の軸線方向への移動を規制されて保持されていることを特徴とする請求項1ないし3のいずれかに記載のトロイダル式無段変速機。
- 前記第2リンク部は、前記第1トラニオンと前記第2トラニオンとを、それぞれ回転可能に保持するように構成されていることを特徴とする請求項1ないし4のいずれかに記載のトロイダル式無段変速機。
