Abstract
A vehicle includes a continuously-variable transmission (CVT) that is supplied with power from an input. The CVT also includes a pair of pulleys, at least one of which having a variator that is configured to translate linearly along an axis of the input. A mechanical lock is configured to selectively lock the input with the variator such that the input and the variator rotate in unison. This allows the hydraulic pressure supplied to the CVT to reduce while the variator and the input remain locked.
Claims13
A continuously-variable transmission (CVT), comprising:
- an input extending along an axis;
- a variator disposed about the axis and configured to translate along the axis with respect to the input;
- and
- a mechanical lock configured to selectively lock the input to the variator, wherein the mechanical lock includes a rocker arm configured to pivot into a cavity to lock the input to the variator.

A vehicle comprising:
- a continuously-variable transmission (CVT) having an input and a variator configured to translate along a portion of the input;
- a mechanical lock configured to selectively lock the input to the variator;
- and
- at least one controller programmed to engage the mechanical lock and reduce line pressure in the CVT while the input is mechanically locked to the variator.
