A continuously variable transmission (CVT) is an automated transmission that can change through a continuous range of gear ratios, typically resulting in better fuel economy in gasoline applications. [1] This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps.

cone CVT varies the effective gear ratio using one or more conical rollers. The simplest type of cone CVT, the single-cone version, uses a wheel that moves along the slope of the cone, creating the variation between the narrow and wide diameters of the cone. The more sophiticated twin cone mesh system is also a type of cone CVT.

2008年4月9日 · In a CVT with oscillating cones, the torque is transmitted via friction from a variable number of cones ( according to the torque to be transmitted ) to a central, barrel-shaped hub. The side surface of the hub is convex according to a determined radius of curvature, which is smaller than the concavity radius of the cones.

The continuously variable transmission (CVT) is a widely used technology in mechanical and automotive systems, providing smooth and continuous variation of the transmission ratio. Within this concept, one of the less conventional but highly promising models is the Cone-Roller CVT, which utilizes cones and an intermediate roller to transmit torque.

A continuously variable transmission (CVT) is a transmission which can change sleeplessly through an infinite number of effective gear ratios between maximum and minimum values. This contrasts with other mechanical transmissions that only allow a …

2019年4月2日 · For instance, Patil et al. [1] employed topology optimization methods to completely redesign a cone continuously variable transmission (CVT) system, which makes a lighter transmission system...

2020年7月31日 · The continuously variable transmission (CVT) is a transmission which is driven by a non-geared drive mechanism and can continuously change the gear ratio. A lot of ingenious and well-structured drive mechanism forms (Fig. 4.1a) have emerged in the development process of the variable speed technology. The widely used metal belt CVT was developed ...

The simplest type of cone CVT, the single-cone version, uses a wheel that moves along the slope of the cone, creating the variation between the narrow and wide diameters of the cone. The more sophiticated twin cone mesh system is also a type of cone CVT.

A cone CVT varies the drive ratio by moving a wheel or belt up and down the axis of conical roller(s). The simplest type of cone CVT, the single-cone version, uses a wheel that moves along the slope of the cone, creating the variation between the narrow and wide diameters of the cone. Some designs of cone CVTs use two rollers.[19][20] The Evans
