Electro-mechanical braking system and vehicle

A vehicle, comprising a wheel and an electro-mechanical braking system, wherein an axial direction of a screw rod in the electro-mechanical braking system is approximately parallel to a brake disc rotation shaft of the wheel. The electro-mechanical braking system comprises:

• a clamp body, wherein the clamp body comprises a first sliding block and a second sliding block, a screw rod, and a gain bridge, the first sliding block is configured to be movably connected to one friction plate and the gain bridge, the gain bridge is configured to drive the one friction plate, the second sliding block is configured to be in transmission connection to the first sliding block and the other friction plate through the screw rod, and the screw rod is configured to be in threaded connection to the second sliding block;
• and
• a driving apparatus, wherein the driving apparatus is configured to drive the gain bridge and the first sliding block and is configured to drive, through a one-way torque limiting apparatus, the screw rod to rotate along an axis of the screw rod relative to the first and the second sliding blocks.
