Description

この様な本例のトロイダル型無段変速機を実施する場合に好ましくは、請求項２に記載した発明の様に、１対の外側ディスクと、内側ディスクと、複数の支持部材と、複数のパワーローラとを備えた構造を採用する。
このうちの両外側ディスクは、互いに対向する軸方向側面をトロイド曲面とし、互いに同心に、且つ、互いに同期した回転を自在に組み合わせる。
又、前記内側ディスクは、前記両外側ディスクの軸方向側面に対向する軸方向両側面をトロイド曲面とし、軸方向に関してこれら両外側ディスク同士の間の中間部に、これら両外側ディスクに対する相対回転を自在に支持する。
又、前記各支持部材は、前記両外側ディスクの軸方向側面とこの内側ディスクの軸方向両側面との間にそれぞれ設けた１対のキャビティに、それぞれ複数個ずつ配置する。
又、前記各パワーローラは、前記両外側ディスクの軸方向側面とこの内側ディスクの軸方向両側面との間にそれぞれ設けた１対のキャビティに、それぞれ複数個ずつ配置する。
更に、前記各支持部材の端部に一体、若しくは一体的にそれぞれ結合したロッドにそれぞれプーリを固定すると共に、これら各プーリのうちの何れかのプーリとプリセスカムとを、一体若しくは一体的に組み合わせて構成する。 When implementing such a toroidal type continuously variable transmission of this example, preferably, like the invention described in claim 2, a pair of an outer disk, an inner disk, a plurality of support members, and a plurality of A structure with a power roller is adopted.
Both of these outer disks have a toroidal curved surface in the axial direction opposite to each other, and can freely combine rotations that are concentric with each other and synchronized with each other .
Further, the inner disk has a toroidal curved surface on both sides in the axial direction facing the axial side surfaces of the outer disks, and relative rotation with respect to the outer disks is performed at an intermediate portion between the outer disks in the axial direction. Support freely.
Each of the support members is disposed in a pair of cavities provided between the axial side surfaces of the outer disks and both axial sides of the inner disks.
A plurality of each of the power rollers is disposed in a pair of cavities provided between the axial side surfaces of the outer disks and both axial sides of the inner disks.
Further, the pulleys are fixed to the rods integrally or integrally connected to the end portions of the respective support members, and any one of these pulleys and the precess cam are integrally or integrally combined. Configure.

Claims

A pair of outer disks that are concentrically and freely combined in rotation with each other , and axially opposite side faces that face the axial side surfaces of these two outer disks are formed as toroidal curved surfaces that face each other in the axial direction. A toroidal curved surface is provided with an inner disk supported in an intermediate portion between the two outer disks in the axial direction so as to be freely rotatable relative to the two outer disks, and the axial side surfaces of the two outer disks and the inner disks. A plurality of support members and power rollers are respectively disposed in a pair of cavities provided between both side surfaces of the support member in the axial direction. The pulleys are fixed to the coupled rods, and any one of these pulleys and the precess cam are integrally connected. Ku is combined integrally, toroidal-type continuously variable transmission according to claim 1.
