摘要： A continuously variable speed transmission mechanism comprises a tubular input shaft connected at an end to an input unit, an output shaft positioned coaxially with the input shaft, connected at an end to an output unit and extending at the other end into the hollow part of the input shaft, an input disk rotatably mounted on the output shaft and adapted to rotate by the driving force transmitted from the input shaft, an output disk fixed on the output shaft and adapted to rotate by the driving force transmitted from the input disk through power rollers, and a thrust bearing positioned between the other end of the output shaft and a corresponding part of the input shaft thereby enabling mutual rotation of the shafts. Wherein the reactive force applied to the input disk at the transmission of driving force is received by the thrust bearing through the input shaft, while the reactive force applied to the output disk is also received by the thrust bearing through the output shaft.

摘要： A continuous belt of a continuously variable transmission for transmitting a driving torque from an input pulley to an output pulley includes a plurality of blocks, links and pins. Each block includes first and second side engagement surfaces. When the continuous belt spans between the input and output pulleys, at least two different engagement points are defined between the blocks and the pulley. Each link includes first and second end portions, an intermediate portion, first and second connecting holes, an outer projection and an inner projection. The first and second connecting holes are defined within the first and second end portions. The outer projection projects from the first and end portion toward a lateral direction of the continuous belt. The inner projection projects from the first end portion in a direction opposite the direction of the outer projection. Each link has a pitch line of the link which passes through center points of the first and second connecting holes. A center line of each link passes equidistant between the outer and the inner projections. The pitch line is parallel to and spaced apart from the center line. The links are inserted into the blocks such that the outer projection of the links are positioned toward the inside of the continuous belt in one of at least two engagement points between the blocks and the pulley and the inner projection of the links are positioned toward the inside of the continuous belt in the other of at least two engagement points.

摘要： This invention relates to a continuously variable transmission which increases the range of potential transmission ratios and thereby decreases the fuel consumption rate, and which is compact in size and thereby increases space in a passenger compartment. The continuously variable transmission has low and high gear trains and a reverse gear train. Each of the low and high gear trains has a pair of meshed gears and a one-way clutch which controls the direction of transmitting the generated torque. The high gear train further has a clutch which engages at a medium or high vehicle speed and disengages at a low vehicle speed. A jaw clutch is slidably mounted on an output shaft and is located in either a first position or a second position. The jaw clutch forms the low gear train when the jaw clutch is in the first position, and the reverse gear train when the jaw clutch is located on the second position.

摘要： A continuously variable belt transmission device, including driving and driven pulley assemblies on parallel axes. Each pulley assembly includes an axially fixed and an axially movable pulley member with confronting conical face which define a V-shaped groove between them whose width is variable according to axial movement of the movable pulley member wherein the axial orders of the fixed and movable pulley members are opposite in the two pulley assemblies. An endless belt assembly is fitted in a power transmitting manner in the V-shaped grooves of the driving and driven pulley assemblies, and thus by alteration of the widths of the grooves the power transmission ratio can be varied. When the widths of the two V-shaped grooves of the two pulley assemblies are substantially equal, with the endless belt assembly being substantially taut between the pulley assemblies, the axial center of the V-shaped driving pulley groove of the driving pulley assembly is, relative to the axial center of the V-shaped driven pulley groove of the driven pulley assemblies, offset towards the axially movable driven pulley member along the axial direction. The maximum amount of skewing of the endless belt assembly is thereby reduced.
摘要翻译：一种连续可变皮带传动装置，包括平行轴上的驱动和从动滑轮组件。每个滑轮组件包括轴向固定和可轴向移动的滑轮构件，其具有相对的锥形面，其在它们之间限定V形槽，其宽度可根据可动皮带轮构件的轴向运动而变化，其中固定和可移动滑轮构件的轴向在两个滑轮组件中相对。在驱动和从动皮带轮组件的V形槽中以动力传递的方式安装环形皮带组件，因此通过改变凹槽的宽度可以改变动力传动比。当两个滑轮组件的两个V形槽的宽度基本上相等时，环形皮带组件在皮带轮组件之间大致拉紧时，驱动滑轮组件的V形驱动皮带轮凹槽的轴向中心是，相对于从动皮带轮组件的V形从动滑轮槽的轴向中心，沿着轴向朝向轴向移动的从动滑轮构件偏移。从而减小了环形带组件的最大倾斜量。
