The invention relates to a disc brake, a brake-by-wire system and a vehicle. The brake comprises a brake caliper body, a first brake block, a brake disc, a transmission mechanism, a rotating motor anda linear motor, wherein the first brake block and the brake disc are arranged in the brake caliper body, the transmission mechanism is used for converting input rotating torque into linear torque tobe output, the rotating motor drives the first brake block to move towards the brake disc through the transmission mechanism, and the linear motor is used for pushing the first brake block to move sothat the first brake block can press the brake disc. By means of the technical scheme, one of the rotating motor and the linear motor can serve as a power source for traveling braking, and the other one can serve as a power source for emergency braking, so that even if any one of the rotating motor and the linear motor breaks down, the other one can normally provide a braking force to achieve braking, and thus reliability and safety performance of the brake system are effectively improved.
本公开涉及一种盘式制动器、线控制动系统以及车辆,该制动器包括:制动钳体、第一制动块、制动盘、传动机构、旋转电机、直线电机,第一制动块和制动盘设置在制动钳体内,传动机构用于将输入的旋转力矩转化为直线力矩输出,旋转电机通过传动机构驱动第一制动块朝向制动盘移动,直线电机用于推动第一制动块移动,以使第一制动块压紧制动盘。通过上述技术方案,旋转电机和直线电机中的一者可以作为行车制动的动力源,另一者可以作为紧急制动的动力源,这样即使旋转电机和直线电机中的任意一者发生故障,另一者也能正常提供制动力,实现制动,从而有效地提高了本公开提供的制动系统的可靠性和安全性能。
