The invention discloses a diaphragm type electric control pressure executing mechanism for an electronic parking system, which comprises an air inlet, a release electromagnetic valve, a parking electromagnetic valve, an air inlet electromagnetic valve, an exhaust electromagnetic valve, a plunger pump and an air outlet cavity, one end of the electromagnetic valve is communicated with the release electromagnetic valve, the other end of the electromagnetic valve is communicated with the release electromagnetic valve, the parking electromagnetic valve and the plunger pump, the release electromagnetic valve is provided with a release control pipe communicated with the plunger pump, and the parking electromagnetic valve is provided with a parking control pipe communicated with the plunger pump. The diaphragm type electric control pressure executing mechanism for the electronic parking system is simple in structure, simple in assembly process, high in cost performance, more beneficial to automatic production, high in sensitivity due to the adoption of the diaphragm type structure, fine in pressure adjustment and not prone to locking during braking when emergency braking is achieved, the parking anti-locking function is achieved more easily, braking comfort is good, and the service life of the braking system is prolonged. And the safety is high.

    本发明公开了一种电子驻车系统用膜片式电控压力执行机构,包括进气口、释放电磁阀、驻车电磁阀、进气电磁阀、排气电磁阀、柱塞泵与出气腔,所述进气口一端与外置气源连通,另一端分别与所述释放电磁阀及所述驻车电磁阀及所述柱塞泵连通,所述释放电磁阀上设置有与所述柱塞泵连通的释放控制管,所述驻车电磁阀上设置有与所述柱塞泵连通的驻车控制管,该电子驻车系统用膜片式电控压力执行机构结构简单,装配工艺简单,性价比高,更有利于自动化生产,且采用膜片式结构,灵敏性高,当实现应急制动时,压力调节细腻,制动时不容易发生抱死,更容易实现驻车防抱死功能,制动舒适性好,安全性高。
