High-Efficiency ONE-BOX Brake Motor Shaft for Cars

The ONE-BOX Brake Motor Shaft is a next-generation actuation component designed specifically for new energy vehicle brake-by-wire systems. By seamlessly integrating a brushless motor with a ball screw assembly, it transforms electronic control signals into instant mechanical thrust to activate the hydraulic piston and create braking pressure. This advanced design removes the dependency on vacuum boosters, effectively solving the vacuum source challenge inherent in electric and hybrid vehicles.

Product RoleApplication Scenarios

The ONE-BOX Brake Motor Shaft serves as a critical link in the braking chain of BEVs and HEVs. It rapidly and precisely converts electronic braking commands into mechanical force to build hydraulic pressure. Acting as the "core engine" of the intelligent braking system, it directly affects brake response speed, regenerative energy capture, and autonomous driving fail-safe redundancy. This component is fundamental to maintaining driver control and vehicle stability under diverse driving conditions — from emergency braking on highways to low-adhesion surfaces in rain or snow.
