The invention discloses a brake-by-wire booster. The brake-by-wire booster comprises a shell, a driving module and a braking module. The shell is provided with a first mounting space; the driving module is mounted in the first mounting space, the driving module comprises a driving assembly and a first transmission assembly, and the driving assembly comprises a rotor; the first transmission assembly is mounted in the mounting cavity, the first transmission assembly comprises a nut and a screw rod, the nut is coaxially arranged in the rotor, the nut is connected with the rotor, and the screw rod is matched with the nut so that the screw rod can move in the axial direction of the screw rod; the brake module is installed outside the shell and is in transmission connection with the lead screw. The rotor, the nut and the lead screw are coaxially arranged, so that the transmission efficiency can be effectively improved, the loss of driving force is reduced, the braking flexibility is improved, meanwhile, due to the coaxial design, the overall integration degree of the structure is high, and the space utilization rate is increased.

    本发明公开一种线控制动助力器,包括:壳体、驱动模块和制动模块;壳体具有第一安装空间;驱动模块安装在第一安装空间内,驱动模块包括驱动组件和第一传动组件,驱动组件包括转子;第一传动组件安装在安装空腔内,第一传动组件包括螺母和丝杆,螺母同轴内设在转子内,且螺母与转子相连接,丝杆与螺母适配,以使丝杆沿其轴向活动;制动模块安装在壳体外,且与丝杆传动连接。通过使转子、螺母和丝杆三者同轴设置,能够有效提高传动效率,减少驱动力的损耗,提高刹车灵活性,同时,同轴的设计使得结构整体集成度高,提高了空间利用率。
