The present application relate to a follow-up mechanism and a brake caliper unit for gauge-changeable bogie, the follow-up mechanism includes a follow-up connector, unlocking members that are located on two sides of the follow-up connector and movably connected to the follow-up connector, a transverse displacement recognition device movably connected to the unlocking members, a toothed locking and positioning device mounted on the follow-up connector, and at least two mutually parallel fixation members; the follow-up connector is in sliding fit with the fixation members, and sliders are fixedly connected at ends of the unlocking members; the toothed locking and positioning device is movably connected to the transverse displacement recognition device and fixation members, respectively; the brake caliper unit comprises a mounting bracket, the follow-up mechanism, and a brake actuator mounted on the mounting bracket, the follow-up mechanism is installed in cooperation with the brake actuator, and the fixation members are fixedly mounted on the mounting bracket. The present application can automatically recognize the orbit change of a train, the follow-up mechanism moves with a wheel by means of its stored elastic force and the unlocking members, and can self-locked at the target gauge position, thus realizing the change in position.
