US 2026/0132831 A1 · ELECTRO-MECHANICAL BRAKING APPARATUS WITH IN-SHAFT LOCKING MECHANISM, SYSTEM, AND VEHICLE

Abstract

This application provides an electro-mechanical braking apparatus, an electro-mechanical braking system, and a vehicle. The electro-mechanical braking apparatus includes a brake motor, a gearbox, a brake, and the locking mechanism. The brake motor drives the brake to brake the vehicle via the gearbox. The locking mechanism is located on a side of the gearbox in an axial direction of a gear shaft of the gearbox. The locking mechanism includes a clutch, an axial moving part, and a locking motor. The clutch is accommodated in an inner hole of the gear shaft. The axial moving part is configured to control the clutch to lock or release the gear shaft. The locking motor is configured to drive the axial moving part to move away from or toward the clutch. The electro-mechanical braking apparatus is small in volume and reliable in parking.
