Description

変速時には、上記各揺動フレーム74、75毎に2対ずつ(各揺動フレーム毎に4個ずつ、トロイダル型無段変速機ユニット全体として合計24個)設けた油圧シリンダ78a、78bのうちの、上記各揺動フレーム74、75の長さ方向一端側に設けた一方の油圧シリンダ78a(78b)を伸長させると共に他方の油圧シリンダ78b(78a)を収縮させて、上記各揺動フレーム74、75を所定方向に所定量だけ揺動変位させる。即ち、上記各揺動フレーム74、75は、それぞれ間隔をあけて互いに平行に配置した1対ずつの支持環60、60同士の間に掛け渡した上記各支持軸77、77に、揺動変位自在に支持している。上記各油圧シリンダ78a、78bは、それぞれ上記各支持環60、60の一部で上記各揺動フレーム74、75の両端部に整合する位置に設けている。そして、上記各油圧シリンダ78a、78bに嵌装したピストン81a、81bと、上記各揺動フレーム74、75の両端部に固定したロッド82a、82bを係合させている。
Of the hydraulic cylinders 78a and 78b provided at the time of shifting, two pairs for each of the swing frames 74 and 75 (four for each swing frame, a total of 24 for the toroidal continuously variable transmission unit as a whole). The one hydraulic cylinder 78a (78b) provided on one end side of each of the swing frames 74 and 75 in the length direction is extended and the other hydraulic cylinder 78b (78a) is contracted to cause the swing frames 74, The 75 is oscillated and displaced in a predetermined direction by a predetermined amount. That is, the swing frames 74 and 75 are swing-displaced on the support shafts 77 and 77 spanned between the pair of support rings 60 and 60 arranged in parallel with each other at intervals. It supports freely. The hydraulic cylinders 78a and 78b are provided at positions that are part of the support rings 60 and 60 and are aligned with both ends of the swing frames 74 and 75, respectively. Then, the pistons 81a and 81b fitted to the hydraulic cylinders 78a and 78b are engaged with the rods 82a and 82b fixed to both ends of the swing frames 74 and 75.
