摘要： A variety of shifter mechanisms are provided for controlling the axial distance between half-pulleys of a split pulley variable transmission, thus controlling the transmission ratio of the variable transmission. Some of these embodiments include a differential such that a variable transmission can be driven and shifted differentially by two inputs. A torque or rotation difference between the inputs results in a change in the transmission ratio and in-common torque or rotation is transmitted through the transmission to an output. The same motors used to drive the output of the transmission are thus also able to effect shifts in the transmission ratio. Accordingly, motor mass that is not being used to effect high-speed shifts may be used to drive the transmission output, and vice versa. The provided shifter embodiments are well-suited to application to nested-pulley variable transmissions, including nested-pulley infinitely variable transmissions.

摘要： The present concept is a continuously variable speed transmission and steering differential. It includes a laterally extending central drive axle driven by an external power source, two pairs of drive sheaves mounted to drive axles, and a means for transmitting rotational energy from the drive sheaves to the drive axles. There are two extended shift arms spaced apart for controlling the positioning of movable drive sheaves. Narrowing or increasing the gap between shift arms, does the same for the gap between the drive sheaves, increasing or decreasing the gear ration respectively which provides speed control. Shifting the shift arms left or right varies the gear ratio between the left and right pair of sheaves, providing differential speed between the left and right driven axles, which provides steering control.

摘要： A continuously variable transmission having an endless V belt running across a driving pulley and a driven pulley, a transmission ratio changing mechanism for changing the running diameters of the belt around the pulleys radially in opposite directions to each other, and a tension-adjusting unit for pressing the belt to obtain belt tension. The tension-adjusting unit includes a tension roller coming into pressure contact with the slack side of the belt from outside, a swing arm having an end rotatably supported on a transmission case, a link member having an end rotatably supporting a shaft of the tension roller and another end rotatably coupled with another end of the swing arm, and an urging member for swingingly urging the swing arm so that the tension roller presses the belt. A linkage structure having two degrees of freedom is used for supporting the tension roller, so that the tension roller can automatically move to a position where it does not interfere with either pulley at any transmission ratio.

摘要： A variable speed transmission in which the output speed is infinitely adjustable within a given speed range and is accurately controlled. The variable speed transmission includes two pulley assemblies that are rotatably connected by an endless chain, control levers and a control screw for varying the effective pitch radius of at least one of the pulley assemblies and the associated chain. The output from one of the pulley assemblies serves as the elliptical ball bearing assembly input that serves to deform a nonrigid external gear of a flexible gear assembly. The output from the other pulley assembly through gears controls a round rigid internal gear that intermittently meshes with the nonrigid external gear. This arrangement provides extremely accurate speed control of the output from the flexible gear assembly that comes form the nonrigid external gear. The pulley assemblies, the endless chain, control levers, and the flexible gear assembly are located within the same compact hollow unitary housing.

摘要： A continuously variable transmission belt guide is mounted next to a driven clutch assembly and in close proximity with the CVT belt at the CVT's lowest drive ratio. The CVT belt connects between a pair of moveable sheaves of the drive and driven clutch assemblies to provide a variable CVT drive ratio between a lowest drive ratio and a highest drive ratio. When contacting the CVT belt, the CVT belt guide prevents a ripple or wave from appearing in the un-tensioned side of the belt, prevents the CVT belt from losing contact with the driven clutch, and prevents undesirable vehicle performance at the lowest drive ratio.
