Title:
車両用変速機
Document Type and Number:
Japanese Patent JP4281764
Kind Code:
B2
Abstract:
A vehicle transmission has at least two driving shafts (10, 11) to which power is transmitted from a power source (1), a driven shaft (13) to which power is transmitted from the driving shafts (10, 11), drive transmission mechanisms (14, 15, 16, 17, 18) disposed between the driving shafts (10, 11) and the driven shaft (13), and a switching mechanism (19, 20, 21, 22) that selectively enables power transmission via the drive transmission mechanisms. The driving shafts (10, 11) are disposed concentrically and fitted rotatably relative to each other. The driving shafts (10, 11) are parallel to the driven shaft (13). A first drive unit (3) is disposed coaxially with the driving shafts (10, 11). A second drive unit (4) is disposed coaxially with the driven shaft (13). The first and second drive units (3, 4) are interconnected so as to send and receive powers changed in energy form to and from each other. The transmission thus constructed is excellent in power transmission efficiency, quietness, vehicle mountability, etc., and can realize continuously variable speed change.
