Abstract:
Ein Grundkörper (3) weist eine gelagerte Welle (4,4') auf, an der ein Antriebsteil (6,6') befestigt ist. Das Antriebsteil (6,6') und das getriebene Teil (7,7') welches auf der Welle (5,5') befestigt ist, können in runder oder nicht runder Form gefertigt sein. Um das Antriebsteil (6,6') mindestens einmal geschlungen liegt ein Antriebselement (8) vor das in Zugrichtung (Α') das getriebene Teil (7,7) mindestens einmal umschlingt und in Zugrichtung (A) zurückgeführt wird zum Antriebsteil (6,6') und dabei formschlüssig die Kraft vom Antriebsteil (6,6') auf das getriebene Teil (7,7') überträgt. Gespannt wird das Antriebselement (8) durch ein Spannelement (11), welches sich vorteilhafterweise auf der Zugseite (Α') befindet. Das Antriebselement (8) wird auf dem Antriebsteil (6,6') oder dem getriebenen Teil (7,7') verschoben, um die Kraftübertragungs-Verhältnisse zu verändern, was in Form von Wechselelementen (10,12) geschehen kann. Das Antriebsteil (6,6') oder/und das getriebene Teil (7,7') kann auch aus mehreren Einzelteilen (9,9') mit Rillen ( 6 ', 7 ' ) oder ohne Rillen bestehen.
Abstract:
Motor potencializador de fuerza constituido por un contenedor (6) de aceite, un sistema conductor de aceite, que entra en funcionamiento por medio de un émbolo (5) que es empujado por medio de un engrane impulsor (3) y retraído por medio de un resorte (4). El engrane impulsor es accionado por medio de un polipasto (1), el cual transmite su fuerza preferentemente con una cadena (38) o banda. Dicho émbolo (5) succiona aceite del contenedor para conducirlo mediante mangueras (8) y lo hace pasar a través de una pluralidad de válvulas check (7), para que accionen por lo menos un pistón hidráulico, el cual mueve una transmisión (18) por medio de un eje (17). Dicha transmisión cuenta con un cono principal (25) y un cono secundario (30), los cuales se accionan por medio de un engrane de reversa y un engrane de directa.

Abstract:
A toothed CVT using a Cone with One Torque Transmitting Member that is coupled by a Transmission Belt to another Cone with One Torque Transmitting Member for which teeth re-engagement between the Torque Transmitting Members and their Transmission Belt is improved. Said CVT uses a slack-side Tensioning Pulley in order to maintain the tension in the slack-side of the Transmission Belt almost constant so as to ensure smooth re-engagement of the Driven Cone; and a Transmission Diameter Compensating Mechanism, which increases the Transmission Diameter of the Driving Cone when the torque being pulled by the Driving Cone is increased, in order to compensate for an increase in "Transmission Belt Teeth Compression" and an increase in "stretching of the tense-side of the Transmission Belt", due to an increase in tension in the tense-side of the Transmission Belt when an increased torque is transmitted; to ensure smooth re-engagement of the Driving Cone.

Abstract:
The present invention provides a continuously variable belt pulley transfer system that addresses prior deficiencies with CVT -type systems, particularly when used with accessory drive systems. The continuously variable belt drive system includes a driving pulley assembly and a driven pulley assembly, with a continuous belt transferring rotary motion between them. A direct electronic actuation mechanism is used for controlling ratio changes on the pulley transfer assembly. An integrated stepper motion is used as the prime mover for the mechanism. A differential planetary roller screw mechanism converts the rotary motion from the stepper motor to axial motion for actuating the sheave poison of the V-shaped belt.

A direct electronic actuation mechanism is utilized to control the ratio changes on the pulley transfer assembly. An integrated stepper motor is utilized along with a planetary roller screw mechanism which converts rotary motion to axial motion for changing the sheave position and thus the drive ratio. The stepper motor includes a permanent magnetic rotor member.

Rotational position adjuster systems that can be used to increase the performance of CVTs utilizing cones with torque transmitting members by eliminating or reducing transition flexing, and/or by maintaining the CVTs in a moveable configuration during transmission ratio changes.
Abstract:
An improvement relating to an infinitely varable ratio transmission having a pair of oppositely oriented conical torque input and output members is disclosed wherein the conical mambers include multi-angled conical surfaces. Further the conical members include longitudinal floating sprocket bars which combined with the multi angled conical surfaces compensate for the effect of an inextensible drive belt as the drive belt is axially moved along the longitudinal length of the torque input and output members.
