A wheel clutch device has two hubs 10, a shaft module 20, an engagement base 30, a clutch base 40, a clutch unit 50 and an abutment unit 60. The shaft module 20 is inserted through the hubs 10 and has a shaft body 21. The engagement base 30 is mounted on one of the hubs 10 and has at least one engagement base groove 31. The clutch base 40 is mounted in the engagement base 30 engaged with the shaft body and has at least one alignment slit 43 aligned with the at least one engagement base groove 31. The clutch unit is mounted around the clutch base and has at least one engagement lump or tooth 51 selectively engaged with the at least one engagement base groove 31 and the at least one alignment slit 43. The abutment unit is combined with the shaft body and abuts the clutch unit. The clutch is useful for electric vehicles such as mobility scooters and makes it easier for a user to push the vehicle when the motor is not working. |
