The invention relates to a drum-type drive-by-wire parking actuator with an alarm function device, which comprises an upper shell, a screw rod assembly, a magnet, a reed switch, a reed switch wire harness, a lower shell, a motor worm assembly, a worm gear bearing assembly, a disc spring seat, a disc spring assembly, a thrust bearing, an inhaul cable assembly and a dust cover, the drum type drive-by-wire parking actuator with the alarm function device is particularly suitable for new energy intelligent vehicles. The drum-type drive-by-wire parking actuator with the alarm function device is installed on a drum-type brake and used in cooperation with a vehicle sound-light alarm device to achieve the alarm function. When the drum brake normally works, the reed switch is in an open circuit state, the stroke of the lead screw assembly is increased after a friction plate of the drum brake is abraded, when the friction plate is abraded to the limit, the lead screw assembly drives the magnet to move to the position near the reed switch, the reed switch is conducted, and the sound-light alarm device works. After the drum brake is replaced with a new friction plate, the lead screw assembly resets, and the alarm is released. The drum type drive-by-wire parking actuator with the alarm function device has the advantages of being easy and convenient to install and operate, safe and reliable.
本发明涉及一种带报警功能装置的鼓式线控驻车执行器,包含上壳体、丝杆组件、磁铁、干簧管、干簧管线束、下壳体、电机蜗杆组件、蜗轮轴承组件、碟簧座、碟簧组件、推力轴承、拉索组件、防尘罩,尤其是适用于新能源智能车辆使用的带报警功能装置的鼓式线控驻车执行器。本发明的带报警功能装置的鼓式线控驻车执行器,安装在鼓式制动器上,与车辆声光报警装置配合使用实现报警功能。正常工作时,干簧管为断路,当鼓式制动器的摩擦片磨损后,丝杆组件的行程增大,当摩擦片磨损到极限,丝杆组件带着磁铁运行到干簧管附近,干簧管导通,声光报警装置工作。鼓式制动器更换新摩擦片后,丝杆组件复位,报警解除。本发明的一种带报警功能装置的鼓式线控驻车执行器,具有安装操作简便,安全可靠的优点。
