Patent ID: 8235848

Claim:
A vehicle transmission having a continuously variable transmission ratio, comprising: a first shaft; a second shaft; a first cone-pulley pair arranged on the first shaft; a second cone-pulley pair arranged on the second shaft; an endless chain belt arranged between the first cone-pulley pair and the second cone-pulley pair; an input shaft; a first dog clutch; a second dog clutch; an output wheel mounted rotatably on the input shaft, the input shaft can be brought into rotational engagement with the first shaft or the second shaft, and the output wheel can be brought into rotational engagement with the other of the first shaft or the second shaft by the first dog clutch or the second dog clutch; a first multi-disk clutch disk and a second multi-disk clutch for transmitting rotational force between the input shaft, the first shaft, the second shaft; a first hydraulically actuated device, which can actuate the first multi-disk clutch and the first dog clutch; a second hydraulically actuated device, which can actuate the second multi-disk clutch and the second dog clutch; a component; and a spring device, wherein the first hydraulically actuated device and the second hydraulically actuated device each have a pressure space which acts upon the component for closing the first multi-disk clutch and the second multi-disk clutch so as to displace the component axially relative to the input shaft and counter to the spring device.
