The invention discloses a wagon electric brake cylinder and a foundation brake device, and relates to the technical field of wagon brake. The electric brake cylinder comprises a driving motor, a telescopic assembly and a transmission assembly, wherein the telescopic assembly comprises a telescopic sleeve and a telescopic rod piece which are in threaded transmission, and the transmission assembly is connected between the telescopic rod piece and a driving motor. Compared with an existing wagon adopting compressed air as driving energy, the problem that due to fatigue and abrasion of componentsafter long-time use, the stroke of a brake piston is changed is solved, the problem of gas leakage does not exist any more, output of the electric brake cylinder is more stable, the system is simplerand more reliable, energy consumption cleaning is achieved, the technical problems that when wheels of an existing wagon are braked through compressed air, the compressed air leaks easily, the relieving performance is poor, and the braking force is weakened easily are solved.
本发明公开了一种铁路货车电制动缸及基础制动装置,涉及铁路货车制动技术领域。该电制动缸包括驱动电机、伸缩组件以及传动组件,伸缩组件包括通过螺纹传动的伸缩套筒与伸缩杆件,传动组件连接于伸缩杆件与驱动电机之间。本发明相对于现有的铁路货车采用压缩空气作为驱动能量的方式,避免了由于长时间运用后部件疲劳及磨耗而导致制动活塞行程变化的问题,也不再存在气体泄漏的问题,电制动缸的输出更稳定,系统更简单可靠,且实现了耗能清洁化,解决了现有铁路货车通过压缩空气制动车轮时压缩空气易泄漏、缓解性能差、容易出现制动力减弱的技术问题。
