Description

更に、上記第一、第二各揺動フレーム53、54を、これら各揺動フレーム53、54の両端部と上記各支持環52、52との間に設けた油圧シリンダ82a、82bにより、揺動変位自在としている。これら各油圧シリンダ82a、82bは、それぞれ上記各支持環52、52の一部で上記各揺動フレーム53、54の両端部に整合する位置に設けている。一方、上記第一、第二各揺動フレーム53、54の両端部で、上記各油圧シリンダ82a、82bに整合する部分にはロッド83a、83bを、上記各支持軸81、81と平行に、上記第一、第二各揺動フレーム53、54の両端部を貫通する状態で支持固定している。そして、上記各油圧シリンダ82a、82bに嵌装したピストン84a、84bと、上記各ロッド83a、83bを係合させている。 Further, the first and second swing frames 53 and 54 are shaken by the hydraulic cylinders 82a and 82b provided between both ends of the swing frames 53 and 54 and the support rings 52 and 52. It can be moved and displaced freely. Each of these hydraulic cylinders 82a and 82b is provided at a position that is a part of each of the support rings 52 and 52 and is aligned with both ends of each of the swing frames 53 and 54, respectively. On the other hand, at both ends of the first and second swing frames 53 and 54, rods 83a and 83b are placed in portions matching the hydraulic cylinders 82a and 82b in parallel with the support shafts 81 and 81. It is supported and fixed so as to penetrate both ends of the first and second swing frames 53 and 54. Then, the pistons 84a and 84b fitted in the hydraulic cylinders 82a and 82b are engaged with the rods 83a and 83b.

尚、これら各ピストン84a、84bの直線運動と上記第一、第二各揺動フレーム53、54の両端部の円弧運動との相違に拘らず、上記各ピストン84a、84bによりこれら第一、第二各揺動フレーム53、54を揺動変位自在とする為、上記各ロッド83a、83bはこれら第一、第二各揺動フレーム53、54の両端部に、上記各ピストン84a、84bの移動方向に対し直角方向に亙る若干の変位自在に支持している。図示の例では、上記各ロッド83a、83bの両端部を、それぞれ支持環52、52に形成した、これら各支持環52、52の直径方向に長い長孔85、85に遊合させているが、これら各長孔85、85の幅を上記各ロッド83a、83bの外径よりも大きくして、上記直角方向に亙る変位を自在としている。 Regardless of the difference between the linear motion of the pistons 84a and 84b and the arc motion of both ends of the first and second swing frames 53 and 54, the first and second pistons 84a and 84b cause the first and second swing frames. (Ii) In order to make the swinging frames 53 and 54 swingable and displaceable, the rods 83a and 83b move the pistons 84a and 84b to both ends of the first and second swinging frames 53 and 54. It supports a slight displacement in the direction perpendicular to the direction. In the illustrated example, both ends of the rods 83a and 83b are loosened to the elongated holes 85 and 85 formed in the support rings 52 and 52, respectively, which are long in the diameter direction of the support rings 52 and 52. The widths of the elongated holes 85 and 85 are made larger than the outer diameters of the rods 83a and 83b so that the rods can be freely displaced in the perpendicular direction.

又、上記各油圧シリンダ82a、82bへの圧油の給排を制御する為の制御弁24aは、前記各支持環52、52に支持している。上記各油圧シリンダ82a、82bへの圧油の給排により上記各揺動フレーム53、54が揺動変位すると、これら各揺動フレーム53、54に支持したトラニオン77、78の外側面に設けたカム面86が、上記制御弁24aに付属のプランジャ87を介してこの制御弁24aのスプール27aを変位させ、上記制御弁24aの切り換えを行なう。このスプール27aと共にこの制御弁24aを構成するスリーブ26aは、変速時には所望の変速比を実現できる様に、制御モータ28aにより、所定位置に変位させておく。この様な制御弁24a及び制御モータ28aは、前記第一入力側ディスク34及び第一出力側ディスク35を含んで構成する第一キャビティ88側に1個、前記第二入力側ディスク37及び第二出力側ディスク38を含んで構成する第二キャビティ89側に1個、トロイダル型無段変速機33全体で2個設けている。そして、第一キャビティ88側の制御モータ28aによりこの第一キャビティ88側の制御弁24aを、第二キャビティ89側の制御モータ28aによりこの第二キャビティ89側の制御弁24aを、マイクロコンピュータを内蔵した図示しない制御器からの指令信号に基づき、互いに同期して(直進状態の場合)、或は互いに独立して(旋回状態の場合)制御する。 Further, the control valve 24a for controlling the supply and discharge of pressure oil to the hydraulic cylinders 82a and 82b is supported by the support rings 52 and 52. When the swinging frames 53 and 54 are swing-displaced due to the supply and discharge of pressure oil to the hydraulic cylinders 82a and 82b, they are provided on the outer surfaces of the trunnions 77 and 78 supported by the swinging frames 53 and 54. The cam surface 86 displaces the spool 27a of the control valve 24a via the plunger 87 attached to the control valve 24a, and switches the control valve 24a. The sleeve 26a forming the control valve 24a together with the spool 27a is displaced to a predetermined position by the control motor 28a so that a desired gear ratio can be achieved at the time of shifting. One such control valve 24a and one control motor 28a are provided on the first cavity 88 side including the first input side disk 34 and the first output side disk 35, and the second input side disk 37 and the second are provided. One is provided on the second cavity 89 side including the output side disk 38, and two are provided on the entire toroidal type continuously variable transmission 33. Then, the control valve 24a of the first cavity 88 side by the first cavity 88 side of the control motor 28a, the second cavity 89 side of the control valve 24a by a second cavity 89 side of the control motor 28a, a microcomputer Based on the command signal from the controller (not shown), the control is performed in synchronization with each other (in the case of straight running state) or independently of each other (in the case of turning state).
