Abstract
An electromagnetic clutch (10), a transmission apparatus (100), and a vehicle. The electromagnetic clutch (10) comprises a transmission shaft (1), a gear switching member (2), and an excitation mechanism; the gear switching member (2) is slidably arranged on the transmission shaft (1) in the axial direction of the transmission shaft (1) and rotates synchronously with the transmission shaft (1); the excitation mechanism comprises two excitation members (31) that are arranged at an interval in the axial direction of the transmission shaft (1); the gear switching member (2) comprises an electromagnetic induction portion (23) located between the two excitation members (31), and the excitation members (31) are used driving the electromagnetic induction portion (23) to move in the axial direction of the transmission shaft (1) so as to drive the gear switching member (2) to switch between different gears.
