Description
自動車用変速装置としてハーフトロイダル型のトロイダル型無段変速機を使用する事が、一部で実施され、周知である。図7〜8は、従来構造のトロイダル型無段変速機の基本構成を示している。このトロイダル型無段変速機は、入力回転軸1の両端寄り部分の周囲に1対の入力ディスク2、2を、それぞれがトロイド曲面である内側面同士を互いに対向させた状態で、前記入力回転軸1と同期した回転を可能に支持している。又、この入力回転軸1の中間部周囲に出力筒3を、この入力回転軸1に対する回転を可能に支持している。又、この出力筒3の外周面には、軸方向中央部に出力歯車4を固設すると共に、軸方向両端部に1対の出力ディスク5、5を、スプライン係合により、前記出力筒3と同期した回転を可能に支持している。又、この状態で、それぞれがトロイド曲面である、前記両出力ディスク5、5の内側面を、前記両入力ディスク2、2の内側面に対向させている。
The use of a half-toroidal toroidal continuously variable transmission as an automobile transmission is partly implemented and well known. 7 to 8 show a basic configuration of a toroidal continuously variable transmission having a conventional structure. In this toroidal continuously variable transmission, a pair of input disks 2 and 2 are disposed around both end portions of the input rotating shaft 1, and the input rotation is performed in a state in which inner surfaces each of which is a toroidal curved surface are opposed to each other. The rotation synchronized with the shaft 1 is supported. An output tube 3 is supported around the intermediate portion of the input rotary shaft 1 so as to be rotatable with respect to the input rotary shaft 1. Further, on the outer peripheral surface of the output cylinder 3, an output gear 4 is fixed at the center in the axial direction, and a pair of output disks 5 and 5 are connected to both ends in the axial direction by spline engagement. Supports the rotation synchronized with. In this state, the inner surfaces of the output disks 5 and 5, each of which is a toroidal curved surface, are opposed to the inner surfaces of the input disks 2 and 2.
[実施の形態の第1例]
請求項1〜2に対応する、本発明の実施の形態の第1例に就いて、図1〜2により説明する。尚、本例を含めて、本発明のトロイダル型無段変速機の特徴は、ストッパ機構22の作動に伴い、各ディスク2、5の内側面とパワーローラ6aの周面との転がり接触部(トラクション部)での有害な滑り(グロススリップ)の発生を防止して、耐久性を確保する為の構造にある。その他の部分の構造及び作用は、前述の図9〜14に示した構造を含め、従来から知られているトロイダル型無段変速機と同様であるから、同等部分に関する図示並びに説明は省略若しくは簡略にし、以下、本例の特徴部分を中心に説明する。
[First example of embodiment]
A first example of an embodiment of the present invention corresponding to claims 1 and 2 will be described with reference to FIGS. The toroidal-type continuously variable transmission of the present invention including this example is characterized by the rolling contact portion between the inner surface of each of the disks 2 and 5 and the peripheral surface of the power roller 6a (in accordance with the operation of the stopper mechanism 22). It has a structure for preventing the occurrence of harmful slip (gross slip ) in the traction section and ensuring durability. Since the structure and operation of the other parts are the same as those of conventionally known toroidal-type continuously variable transmissions, including the structures shown in FIGS. 9 to 14 described above, illustration and explanation of equivalent parts are omitted or simplified. In the following, the characteristic part of this example will be mainly described.
