CONTINUOUSLY VARIABLE TRANSMISSION APPARATUS

摘要

Provided is a continuously variable transmission mechanism of a traction drive type having: a shaft (60) which functions as the center of rotation; relatively rotatable first and second rotating members (10, 20) that are disposed to face each other on the shaft (60) and share a first rotation center axis (R1); plural planetary balls (50) that have a second rotation center axis (R2), are radially disposed around the first rotation center axis (R1) as the center, and are held between the first and second rotating members (10, 20); and an iris plate (80) that changes the gear ratio between an engine-side input shaft (11) and a drive wheel side output shaft (21) by tilting each of the planetary balls (50) with respect to the first rotation center axis (R1). When an engine is started, the gear ratio is controlled to an acceleration side rather than maximum deceleration.

主权项

1. A continuously variable transmission apparatus comprising:
a continuously variable transmission mechanism of a traction drive type that includes: a transmission apparatus shaft that serves as a center of rotation, a first rotating element and a second rotating element that are disposed to face each other on the transmission apparatus shaft, share a first rotation center axis, and are capable of relative rotation, plural rolling members that have a second rotation center axis, are radially disposed around the first rotation center axis as the center, and are held by the first rotating element and second rotating element, and a transmission device that changes a gear ratio between an input shaft on an engine side and an output shaft on a drive wheel side by tilting the each rolling member with respect to the first rotation center axis; and a controller configured to control the gear ratio to an acceleration side and start the engine at a gear ratio in an acceleration side from maximum deceleration in a period from ignition-on to the engine start.
