The invention discloses a limiting device, a steer-by-wire system and a vehicle. The limiting device comprises a shell, a rotating shaft, a lead screw, a first limiting stopper, a second limiting stopper and a ball returning device. A limiting cavity is formed in the shell. The rotating shaft has a limiting shaft section. The lead screw is arranged on the periphery of the limiting shaft section, and a first ball groove is spirally formed in the lead screw. The first limiter and the second limiter are arranged on the limiting shaft section and located at the two ends of the lead screw respectively. The sliding part is arranged in the limiting cavity and slidably connected with the shell, the sliding part is arranged on the periphery of the lead screw in a sleeving mode, a second ball groove is formed in the inner periphery of the sliding part, and the second ball groove is matched with part of the first ball groove to form a ball channel. The ball returning device is provided with a ball returning channel, one end of the ball returning channel is communicated with one end of the ball channel, and the other end of the ball returning channel is communicated with the other end of the ball channel. The sliding part abuts against the first limiting stopper or the second limiting stopper through movement. In this way, excessive rotation of the rotating shaft can be limited.
