2 . The clutch assembly according to claim 1 , wherein the first end is an output end of the clutch assembly, and the second end and the third end are input ends of the clutch assembly.

3 . The clutch assembly according to claim 1 , wherein the second end is an output end of the clutch assembly, and the first end and the third end are input ends of the clutch assembly.

4 . The clutch assembly according to claim 1 , wherein along a thickness direction of the first transmission member, the first clutch portion and the third clutch portion are respectively connected to two sides of the first transmission member; and

along the thickness direction of the first transmission member, a projection of the first clutch portion and a projection of the third clutch portion at least partially overlap.

5 . The clutch assembly according to claim 1 , wherein an outer periphery of the clutch body comprises teeth as the first transmission member.

6 . The clutch assembly according to claim 1 , wherein the first transmission member, the first clutch portion, and the third clutch portion are integrally formed.

7 . The clutch assembly according to claim 1 , wherein the first transmission member is connected to the countershaft, and the second clutch portion and the fourth clutch portion are rotatably disposed on the countershaft.

8 . The clutch assembly according to claim 7 , further comprising a housing, a first bearing, and a second bearing, wherein:
