Braking device for a drive assembly of a vehicle, and a vehicle having the drive assembly

A braking device for a drive assembly of a vehicle, comprising:

• an input shaft,
• a brake, wherein the brake has a first braking partner and a second braking partner, wherein the first braking partner is arranged in a stationary manner in the braking device, and
• a brake coupling device, wherein the input shaft, the brake and the brake coupling device form sub-portions of a torque path through the braking device,
• wherein the brake coupling device is a synchronization device with a first coupling partner, a second coupling partner, and a shift collar, wherein, in a coupling state, the shift collar rotationally fixedly couples the first coupling partner to the second coupling partner in a form-fitting manner to close the torque path, and, in a release state, decouples the first coupling partner from the second coupling partner in order to open the torque path, and
• wherein a one of the first coupling partner and the second coupling partner is connected to the input shaft for rotation therewith.
