The invention discloses a braking device with active braking and parking braking functions, which comprises a shell, a braking main cylinder is arranged on one side of the shell, the braking main cylinder is provided with a piston, a nut is arranged on the shell, and a screw rod is in threaded connection with the nut; a motor is arranged on the shell and drives the nut to rotate, so that the screwrod is driven to move linearly through threads of the nut; in the stroke of the screw, the first end of the screw can abut against the piston of the brake master cylinder to push the piston to move towards one side of the brake master cylinder, and therefore active braking is achieved. The braking device with the active braking function and the parking braking function can achieve the active braking function, is suitable for a driverless logistics vehicle brake-by-wire system, can control the braking force and achieve active braking according to requirements, and is compact in structure and low in cost. A screw transmission mode is adopted, active braking can be achieved, and when a motor is powered off, a screw transmission pair is self-locked, and parking braking is achieved.
本发明公开了一种具有主动制动和驻车制动功能的制动装置,其包括壳体,壳体的一侧设置有制动主缸,制动主缸具有活塞,壳体上设置一螺母,一螺杆与螺母螺纹连接;壳体上设置一电机,电机驱动螺母旋转,从而通过螺母的螺纹驱动螺杆直线移动;在螺杆的行程中,螺杆的第一端可抵靠在制动主缸的活塞上以推动活塞向制动主缸一侧移动,从而实现主动制动。本发明的具有主动制动和驻车制动功能的制动装置可实现主动制动功能,适用于无人驾驶物流车线控制动系统,可根据需求,控制制动力大小,实现主动制动、结构紧凑、成本低;采用螺杆传动方式,不仅可以实现主动制动,当电机断电时,螺杆传动副自锁,实现驻车制动。
