Description

又、図19に示したトロイダル型無段変速機用入力側ディスクユニット44は、互いに別体の部品である、入力軸15と、カム板10と、入力側ディスク2Aと、ローラ12、12と、保持器11と、予圧ばね49とを、トロイダル型無段変速機への組み付け以前に、このトロイダル型無段変速機の組立完了後の位置関係に予め組み立てている。この様なトロイダル型無段変速機用入力側ディスクユニット44を構成する為、入力軸15の一端部(図19の左端部)に固設した鍔部46の内側面にカム板10を玉軸受47により、上記入力軸15に対する回転自在に支持している。又、この入力軸15の中間部一端寄り部分の周囲に上記入力側ディスク2Aを、ボールスプライン48を介して支持している。従ってこの入力側ディスク2Aは、上記入力軸15に、この入力軸15に対する軸方向に亙る変位とこの入力軸15と同期した回転を自在に支持している。又、上記カム板10の内側面に形成した駆動側カム面13と、上記入力側ディスク2Aの外側面に形成した被駆動側カム面14との間に複数個のローラ12、12を挟持して、ローディングカム式の押圧装置9を構成している。又、上記各ローラ12、12は、全体を円輪状に形成した保持器11により、転動自在に保持している。又、上記入力軸15の一端部外周面に形成した段部と上記入力側ディスク2Aの外側面との間には、予圧ばね49を設けている。この予圧ばね49は、押圧装置9が押圧力を発生させる以前に、上記入力側ディスク2Aをパワーローラ8、8(図11〜16参照)に押圧する為のものである。 Further, the input side disc unit 44 for the toroidal continuously variable transmission shown in FIG. 19 includes an input shaft 15, a cam plate 10, an input side disc 2A, and rollers 12 and 12, which are separate parts from each other. , The cage 11 and the preload spring 49 are pre-assembled in a positional relationship after the assembly of the toroidal continuously variable transmission is completed before assembling to the toroidal continuously variable transmission. In order to form the input side disc unit 44 for such a toroidal continuously variable transmission, a cam plate 10 is ball-beared on the inner surface of the flange portion 46 fixed to one end of the input shaft 15 (the left end in FIG. 19). 47 rotatably supports the input shaft 15. Further, the input side disc 2A is supported around the portion near one end of the intermediate portion of the input shaft 15 via a ball spline 48. Therefore, the input side disk 2A freely supports the displacement along the axial direction with respect to the input shaft 15 and the rotation synchronized with the input shaft 15 on the input shaft 15. Further, a plurality of rollers 12 and 12 are sandwiched between the drive-side cam surface 13 formed on the inner surface of the cam plate 10 and the driven-side cam surface 14 formed on the outer surface of the input-side disk 2A. Therefore, a loading cam type pressing device 9 is configured. Further, each of the rollers 12 and 12 is rotatably held by a cage 11 formed in an annular shape as a whole. A preload spring 49 is provided between the step portion formed on the outer peripheral surface of one end of the input shaft 15 and the outer surface of the input side disc 2A. The preload spring 49 is for pressing the input side disk 2A against the power rollers 8 and 8 (see FIGS. 11 to 16) before the pressing device 9 generates the pressing force.
