Embodiment Construction

[0025] The following detailed description is directed to certain specific embodiments of the present invention. However, the invention can be implemented in many different ways as defined and covered by the claims. In this specification, in the various drawings referred to, the same components are denoted by the same reference numerals. Furthermore, embodiments of the invention may include several novel features, no one of which is solely responsible for its required attributes or which are essential to practicing the invention described herein.

[0026] The present invention includes a continuously variable transmission that can be used in conjunction with any type of machine that requires a transmission. For example, transmissions can be used in (i) motorized vehicles such as automobiles, motorcycles, or boats, (ii) non-motorized vehicles such as bicycles, tricycles, scooters, exercise equipment, or (iii) industrial equipment such as drill presses, power equipment , or loo...

Abstract

A continuously variable transmission is disclosed for use in rotationally or linearly powered machines and vehicles. The single axle transmission provides a simple manual shifting method for the user. An additional embodiment is disclosed which shifts automatically dependent upon the rotational speed of the wheel. Further, the practical commercialization of traction roller transmissions requires improvements in the reliability, ease of shifting, function and simplicity of the transmission. The disclosed transmission may be used in vehicles such as automobiles, motorcycles, and bicycles. The transmission may, for example, be driven by a power transfer mechanism such as a sprocket, gear, pulley or lever, optionally driving a one way clutch attached at one end of the main shaft.

Description

technical field [0001] The field of the invention relates to transmissions. The present invention relates more particularly to continuously variable transmissions. Background technique [0002] In order to provide a continuously variable transmission, traction roller transmissions have been developed in which power is transmitted between torque input and output discs via traction rollers supported in a housing. In such a transmission, traction rollers are mounted on each support structure so that when the support structure rotates, the traction rollers engage torque discs on circles of different diameters depending on the desired transmission. It depends. [0003] However, these conventional solutions have had limited success, for example, in US Patent No. 5,236,403 to Schievelbusch, which discloses a drive hub for a vehicle having a variable adjustable transmission ratio. Schievelbusch teaches the use of two spacers, one on each side of the traction rollers, to skew the ...
