Problems solved by technology

[0007] Certain mechanical issues have consistently affected clutchless multi-ratio transmissions, limiting their widespread use; in particular, their ability to operate effectively and efficiently at high speeds or under heavy loads in practical applications
Additionally, ratcheting, slippage and tensioning issues can limit the commercial viability of such systems by reducing reliability, increasing wear, etc.

Embodiment Construction

[0028] The present invention relates to a portion of a power transmission that changes the transmission ratio under load and to a plurality of pulleys divided into segments that move in channels or on rails along an axis of rotation into and out of a toothed belt or chain path. In this drive system, when segments of a plurality of toothed, concentric and coaxial pulleys move axially into or out of a toothed belt or chain from either side of the belt or chain along a channel or track The movement of the pulley segments is coordinated by a synchronization and timing system, and the coordinated movement of the pulley segments allows the belt or chain to change engagement between multiple concentric pulleys without interrupting their rotation or movement through the belt or chain transmission of power. This is achieved by enabling the teeth of the belt to be continuously engaged by at least one toothed pulley, and in transition, as the belt changes engagement between the pulleys,...

Abstract

The invention provides a pulley transmission, which comprises a pulley component mounted on a shaft. The pulley component comprises a core pulley, a first disc conveying belt, a second disc conveying belt and a pulley section group, the first disc conveying belt and the second disc conveying belt are located on opposite sides of the core pulley and are separated by the core pulley, the pulley section group comprises a first pulley section subgroup supported by the first disc conveying belt and a second pulley section subgroup supported by the second disc conveying belt, pulley sections of the first pulley section subgroup can slide towards the second disc conveying belt from non-joint states to joint states, pulley sections of the second pulley section subgroup can slide towards the first disc conveying belt from non-joint states to joint states, and the pulley sections of the first pulley section subgroup and the pulley sections of the second pulley section subgroup are arranged in a mutual staggered manner and form a combination pulley larger than the core pulley when in the joint states.

Description

[0001] This application is a divisional application of the Chinese patent application submitted on May 19, 2005 with the application number 200580051146.8 and the title of the invention "Synchronous Segment Interchangeable Pulley Transmission System". [0002] Cross References to Related Applications [0003] This application claims the benefit of US Provisional Patent Application No. 60 / 572075, filed May 19, 2004, entitled SYNCHRONIZED SEGMENTALLY INTERCHANGING PULLEY TRANSMISSION SYSTEM. technical field [0004] The present invention relates to transmission systems, and more particularly to multi-ratio transmissions. Background technique [0005] Over the past century, many attempts have been made to develop multi-ratio transmissions capable of shifting under load. Potential applications for such drivetrains are numerous, including motor vehicles, human-powered vehicles, marine vessels, and even turbines for power generation.
