摘要： A continuously-variable transmission (CVT) assembly is employed for transmitting a torque from an external power-source. The CVT includes a variable-diameter input pulley and a variable-diameter output pulley, each having a respective range of adjustment. The CVT also includes a continuous torque-transmitting element extending between the variable-diameter input pulley and the variable-diameter output pulley, and thereby operatively connecting the input pulley to the output pulley. The CVT additionally includes a first elastic element having a first zero stiffness over the range of adjustment of the variable-diameter input pulley and configured to apply a first constant spring clamping force via the input pulley to the continuous torque-transmitting element. Furthermore, the CVT includes a second elastic element having a second zero stiffness over the range of adjustment of the variable-diameter input pulley and configured to apply a second constant spring clamping force via the output pulley to the continuous torque-transmitting element.

摘要： A continuously variable speed transmission and steering differential having a central drive axle, two pairs of sheaves and two shift arms. The drive axel is driven by an external power source. The two pairs of sheaves, left and right, are mounted to the drive axel. Each pair of sheaves includes a fixed drive sheave and a movable drive sheave. Each movable drive sheave is positioned by a shift arm. Shifting the shift arms left or right varies the gear ratio between the left and right pair of sheaves thereby providing steering control. Narrowing the distance between the shaft arms increases the gear ratio and consequently puts the transmission into a higher gear, thereby providing speed control.

摘要： Two input-shaft-side fixed sheaves of respective first and second pulley-type continuously variable transmission mechanisms are integrally connected and secured to each other while their back sides abut against each other. One of output-shaft-side movable sheaves and the other of output-shaft-side fixed sheaves are provided between one of the output-shaft-side fixed sheaves and the other of the output-shaft-side movable sheaves while their back sides abut against each other, so as to be rotatable relative to each other and so as to be movable together on a sun-gear input shaft. The one of the output-shaft-side movable sheaves is formed consecutively with an input shaft of a planetary carrier of a planetary gear mechanism. The other of the output-shaft-side fixed pulleys is formed consecutively with an input shaft of a sun gear of the planetary gear mechanism.

摘要： A continuously variable transmission has dual driving connections extending between a first shaft and a second shaft. The driving connections generally include a drive pulley, a driven pulley and a belt. The pulleys each comprise a fixed portion and an axially moveable portion. Movement between the two portions changes an effective diameter of the pulley. The moveable portions of the drive pulley are positioned next to one another on the first shaft and the moveable portions are interposed between the fixed portions of the drive pulleys. The fixed portions of the driven pulleys, on the other hand, are interposed between the moveable portions. The driven pulleys are free to rotate relative to the second shaft. A differential is positioned between the fixed portions of the driven pulleys, connects the two fixed portions and transfers the torque from the driven pulleys to the second shaft.

摘要： Various configurations of a continuously variable transmission include a drive pulley, a driven pulley and a belt extending therebetween. The drive pulley is generally comprised of a moveable sheave half and a fixed sheave half. The moveable sheave half is freely rotatable relative to the drive shaft and the fixed sheave half. Torque is transferred between the moveable sheave half and the stationary sheave half through the use of a roller bearing and channel race arrangement; however, the roller bearings are freely translatable within the channel races. The continuously variable transmission also features a differential positioned between the two output pulleys and an articulating member positioned between the two input pulleys. These two members operate together to eliminate bucking of the belts caused by differences in driven speeds of the two driven pulleys in a parallel configuration of the variable speed transmission. Additionally, a method of assembling the transmission is also described.

摘要： In a vehicle or the like, a source of power is connected to a drive shaft. Two pairs of pulley halves are splined to this shaft and can be moved apart and together and are rotated by the shaft. Driven shafts also carry pairs of pulley halves which are splined thereto and can be moved therealong and belts extend between corresponding pulley halves on the drive shaft and corresponding pulley halves on the driven shafts. A pair of spur gears are journalled for partial rotation and mesh with one another, there being one pair for each two sets of pulley halves and a third drive gear engages between the innermost gears of said spur gears so that movement of this drive gear causes equal and simultaneous rotation of the spur gears. Levers are secured to the spur gears and are operatively connected to the pulley halves so that when the drive gear is rotated, one of the sets of pulley halves are moved apart on one of the shafts whereas the other set are moved together by equal amount and vice versa. This permits belts extending between the sets of pulley halves to increase or decrease the speed of the driven shafts. The drive gear is connected to a steering mechanism and with the driven shaft being connected to the drive wheels on each side of the vehicle, easy and accurate steering is accomplished by speeding up one set of drive wheels and decreasing the speed of the other and vice versa. A winch assembly is connected to the drive shaft by a similar arrangement thus enabling the speed of the winch to be controlled accurately which is of particular importance when the winch is being used to disengage the vehicle from mud, snow or the like under which circumstances the winch speed can synchronize exactly with the speed of the drive wheels so that both the winch and the drive wheels can assist in extracting the vehicle from the mired position.
摘要翻译：在车辆等中，动力源连接到驱动轴。两对滑轮半体花键连接到该轴上，并可以分开移动并一起转动。驱动轴还带有一对滑轮半部，其带有花键并可沿其移动，并且带在驱动轴上的相应滑轮半部和从动轴上的对应的滑轮半部之间延伸。一对正齿轮被轴颈部分旋转并彼此啮合，每组两个滑轮半部有一对，第三个传动齿轮啮合在所述正齿轮的最内齿轮之间，使得该驱动齿轮的运动相等并同步旋转正齿轮。杠杆被固定到正齿轮并且可操作地连接到滑轮半部，使得当驱动齿轮旋转时，一组滑轮半部中的一个在一个轴上移动分开，而另一组在一起移动相等量，反之亦然。这允许在两组滑轮半部之间延伸的带增加或减小从动轴的速度。驱动齿轮连接到转向机构，并且从动轴连接到车辆两侧的驱动轮，通过加速一组驱动轮并降低其他驱动轮的速度来实现简单和精确的转向反之亦然。绞车组件通过类似的装置连接到驱动轴，从而能够精确地控制绞车的速度，这在绞车被用于使车辆脱离泥土，雪等等时特别重要，在这种情况下绞车速度可以与驱动轮的速度精确地同步，以便绞盘和驱动轮可以帮助从膛位提取车辆。
