Abstract
A lay-shaft assembly for use in a vehicle transmission includes a clutching mechanism with a synchronization assembly arranged for synchronizing rotation of a driven gearwheel with a first gearwheel or a second gearwheel. The first and second gearwheels extend adjacently with respect to each other along the central axis, and the synchronizing assembly is positioned between adjacent respective outer circumferential surfaces of the adjacent first and second gearwheels and the sleeve. A ring-shaped biasing means support and a complementary biasing means insert for placing onto the ring shaped biasing means support.

A lay-shaft assembly for use in a vehicle transmission, comprising:
- a lay-shaft arranged rotatably around a central axis;
- a first gearwheel arranged rotatably around the lay-shaft and the central axis;
- a second gearwheel arranged around the lay-shaft around the central axis;
- and
- a clutching assembly arranged rotatably around the lay-shaft and the central axis and comprising:
- a driven gearwheel, and
- a clutching mechanism comprising a movable sleeve for selectively coupling rotation of the driven gearwheel to either of the first gearwheel and the second gearwheel,
- wherein the clutching mechanism further comprises a synchronization assembly arranged for synchronizing rotation of the driven gearwheel with the first gearwheel or the second gearwheel,
- wherein the first and second gearwheels extend adjacently with respect to each other seen along the central axis, and
- wherein the synchronizing assembly is positioned between adjacent respective outer circumferential surfaces of the adjacent first and second gearwheels and the sleeve.
A ring-shaped biasing means support for use in a clutching mechanism comprising a movable cylindrically shaped clutching sleeve, the ring-shaped support comprising:
- one or more first supporting structures positioned at an outer side of the ring-shaped biasing means support and configured to contact with respective one or more complementary supporting structures at an inner side of the sleeve, such that the ring-shaped support is supported by the sleeve and rotates with the sleeve around a central axis when the ring-shaped biasing means support is placed along the inner side of the sleeve;
- and
- one or more second supporting structures each at least partially positioned along an outer side of the ring-shaped support and configured to support biasing means configured for biasing the sleeve to a central position with respect to the ring-shaped biasing means support,
- wherein the movable cylindrically shaped clutching sleeve is movable to selectively couple rotation of a driven gearwheel to either of a first gearwheel and a second gearwheel with the first gearwheel and the second gearwheel being adjacent to each other along the central axis.
