Electronic vehicular transmission, controllable coupling assembly and coupling member for use in the assembly
View Patent ↗An electronic vehicular transmission, a controllable coupling assembly and a coupling member for use in the assembly are provided. The member is configured for rotation about a rotational axis and includes a first coupling face oriented to face axially along the axis and has a set of pockets angularly-spaced about the axis. Each of the pockets receives a first locking element and defines a first load-bearing surface adapted for abutting engagement with a load-bearing surface of its respective first locking element. A second coupling face is oriented to face radially with respect to the axis and has a set of locking formations. Each of the set of locking formations defines a second load-bearing surface adapted for abutting engagement with a load-bearing surface of a second locking element.
1. A coupling member for use in a controllable coupling assembly, the member being configured for rotation about a rotational axis, the member comprising:
a first coupling face oriented to face axially along the axis and having a set of pockets angularly-spaced about the axis, each of the pockets receiving a first locking element and defining a first load-bearing surface adapted for abutting engagement with a load-bearing surface of its respective first locking element; and
a second coupling face oriented to face radially with respect to the axis and having a set of locking formations, each of the set of locking formations defining a second load-bearing surface adapted for abutting engagement with a load-bearing surface of a second locking element.
2. The coupling member as claimed in claim 1 , wherein the member is a plate and wherein the set of pockets are forward pockets and the set of locking formations are spaced-apart reverse cams.
3. The coupling member as claimed in claim 2 , wherein the reverse cams are greater in number than the forward pockets.
4. The coupling member as claimed in claim 2 , wherein the spaced-apart reverse cams are spaced-apart locking teeth.
5. The coupling member as claimed in claim 2 , wherein the plate has a width and wherein each reverse cam extends the entire width of the plate.
6. The coupling member as claimed in claim 1 , wherein the member is a splined ring having an outer circumferential surface formed with the set of locking formations.
7. The coupling member as claimed in claim 1 , wherein the set of pockets are forward pockets for receiving forward locking elements and the set of locking formations are reverse locking formations.
8. A controllable coupling assembly having multiple operating modes, the assembly comprising:
first and second coupling members supported for rotation relative to one another about a common rotational axis, the first coupling member including:
a first coupling face oriented to face axially along the axis and having a set of pockets angularly-spaced about the axis, each of the pockets receiving a first locking element and defining a first load-bearing surface adapted for abutting engagement with a load-bearing surface of its respective first locking element; and
a second coupling face oriented to face radially with respect to the axis and having a set of locking formations, each of the set of locking formations defining a second load-bearing surface adapted for abutting engagement with a load-bearing surface of a second locking element.
9. The assembly as claimed in claim 8 , wherein the first coupling member is a plate and wherein the set of pockets are forward pockets and the set of locking formations are spaced-apart reverse cams.
10. The assembly as claimed in claim 9 , wherein the reverse cams are greater in number than the forward pockets.
11. The assembly as claimed in claim 9 , wherein the spaced-apart reverse cams are spaced-apart locking teeth.
12. The assembly as claimed in claim 9 , wherein the plate has a width and wherein each reverse cam extends the entire width of the plate.
13. The assembly as claimed in claim 8 , wherein the first coupling member is a splined ring having an outer circumferential surface formed with the set of locking formations.
14. The assembly as claimed in claim 8 , wherein the set of pockets are forward pockets for receiving forward locking elements and the set of locking formations are reverse locking formations.
