Precision ONE-BOX Actuator Shaft for Brake-by-Wire

The ONE-BOX Actuator Shaft is a high-performance electromechanical core component for new energy vehicle brake-by-wire systems. It integrates a brushless motor with a precision ball screw, converting electronic control signals into powerful mechanical thrust in milliseconds to directly drive the hydraulic piston and generate braking pressure. This innovation eliminates the need for a vacuum booster — a critical solution for EVs and hybrids that lack a stable vacuum source.
